+# NC chroot / default-drive resolution — moka caches (vs 2 queries/request)
+
+With app-password verification already cached (5 min) and user flags cached
+(30 s), the NextCloud basic-auth middleware still resolved the chroot from
+scratch on EVERY protected NC request: `find_default_for_user` (drives JOIN
+folders) + `get_folder(root_id)` (folders by PK) — 2 uncached round-trips + 2
+pool checkouts before the handler even ran, for values that change only on
+provisioning / drive deletion / a root-folder rename. The native `/webdav`
+surface repeated the drive lookup per request (Mode-B scope resolution, MOVE
+and COPY twice), WOPI once per call.
+
+Changes:
+
+1. `DrivePgRepository::find_default_for_user` memoised (moka, 30 s TTL —
+   same tier as `drive_role_cache`), invalidated on personal-drive creation,
+   drive deletion and policy updates. Only `Ok` is cached, so the
+   provisioning idempotency check still sees the live table.
+2. NC middleware markerless-chroot `FolderDto` cached by root-folder id
+   (30 s TTL). Only the markerless branch — the drive-marker branch keeps
+   its per-request `get_folder_with_perms` authz.
+
+Staleness: bounded at 30 s for a root-folder *rename* (doesn't pass through
+the repo); every other mutation invalidates explicitly.
+
+## Reproduce
+
+```bash
+cargo run --release --features bench --example bench_chroot_cache
+# tunables: BENCH_POOL=20 BENCH_SECONDS=4 BENCH_CONCURRENCIES=8,64

+# WebDAV dead-properties — batched per-page fetch (vs per-child N+1)
+
+The streaming PROPFIND walkers (native `webdav_handler.rs`, NextCloud
+`nextcloud/webdav_handler.rs`, plus both NC REPORT handlers) fetched dead
+properties **one child at a time, sequentially** — one DB round-trip per file
+and per subfolder of every Depth:1 listing. On top, every
+`DeadPropertyStore` query filtered with `folder_id IS NOT DISTINCT FROM $1 AND
+file_id IS NOT DISTINCT FROM $2`, which PostgreSQL cannot serve from a B-tree
+index (`IS NOT DISTINCT FROM` is not an indexable operator) — so each of those
+N round-trips also degraded to a **sequential scan** as the table grew.
+
+Changes:
+
+1. `DeadPropertyStore::get_all_for_files / get_all_for_folders` — ONE
+   `file_id = ANY($1)` round-trip per 500-child PROPFIND page (indexable via
+   the partial unique indexes from migration 20260830000001).
+2. All single-resource queries (`get`, `get_all`, `remove`) now filter on the
+   concrete column (`file_id = $1` / `folder_id = $1`) instead of the
+   NULL-tolerant pair — index scans instead of seq scans.
+3. All four handler loops replaced with one batched map lookup per page.
+
+## Reproduce

+# Companion fixes — same measured unit economics, no dedicated harness
+
+These changes share their cost model with benches that already exist, so
+instead of near-duplicate harnesses each entry cites the bench that measured
+its unit price. (The per-query unit prices below: sequential indexed point
+SELECT ≈ 0.25–0.55 ms and `= ANY($1)` batch ≈ 1–1.5 ms/500 ids from
+benches/DEAD-PROPS.md; manifest-row fetch p50 0.44–4.4 ms from
+benches/BLOB-MANIFEST.md; moka hit ≈ 1 µs from benches/CHROOT-CACHE.md.)
+
+## 1. Content-search ReBAC re-verification — batched (SEARCH-REBAC)
+
+`SearchService::lookup_content_hits` re-verified up to `CONTENT_HITS_LIMIT =
+200` Tantivy hits with sequential `authz.check(Read, File)` calls — each a
+point SELECT on owner-cache miss (distinct file ids ⇒ ~always). New
+`AuthorizationEngine::check_files_read_batch` (default = the old loop, so
+mocks/other impls stay correct; `PgAclEngine` override): ONE
+`id = ANY($1)` drive resolution + cached per-drive role + per-file cascade
+only for drive-floor misses. Decision-equivalent; per 200-hit search:
+**~200 sequential round-trips (≈ 50–110 ms of DB chatter) → 1–2 queries
+(≈ 1–3 ms)**. Also primes the owner cache for the hits' follow-up requests.
+
+## 2. Batch-ZIP downloads — no per-file authz/Recent (ZIP-BATCH-AUTHZ)
+
+`BatchOperations::add_folder_subtree_to_zip` had already authorized the
+subtree ROOT (`get_folder_with_perms`), yet every enumerated file still paid
+`get_file_stream_with_perms` = 1 authz point SELECT + a Recent-hook spawn
+issuing 2 writes (INSERT … ON CONFLICT + prune DELETE). A 2,000-file folder
+ZIP ⇒ ~6,000 extra statements. Subtree entries now use the plain
+`get_file_stream` — exactly what `ZipService::create_folder_zip` (the native
+folder-download path) has always done. Explicitly-selected top-level files
+keep per-file authz + Recent. Unit price: DEAD-PROPS.md sequential rows —
+**~1.5–4.5 s of DB chatter removed** from a 2,000-file archive, plus the ZIP
+no longer floods Recents with every archived file.
+
+## 3. CDC manifest RAM cache (MANIFEST-CACHE)
+
+Every stream / range / full read of a CDC blob paid one
+`chunk_manifests` row fetch first — p50 0.44 ms (4.4 ms under pool pressure,
+benches/BLOB-MANIFEST.md), on the hottest read paths there are (media
+serving, thumbnails, range seeks). Manifests are immutable by content
+address, so `DedupService` now memoises them (moka, weight-bounded 32 MiB,
+60 s TTL, positive-only so background rechunking is honoured immediately;
+invalidated post-commit on the two delete paths). Warm read: **0.44–4.4 ms →
+~1 µs** (CHROOT-CACHE.md's moka row) and one fewer pool checkout per read —
+range-seek storms (video scrubbing) hit this every request.
+
+## 4. Public share landing — 3 round-trips → 1 atomic UPDATE (SHARE-ACCESS)
+
+`GET /api/s/{token}` ran find_share_by_token (with a correlated
+`MIN(expires_at)` subquery), a full-row UPDATE writing back a Rust-side
+increment (racy: lost updates between concurrent visitors, and it rewrote
+`item_name`/`password_hash` wholesale — clobbering concurrent owner edits),
+then the handler's follow-up fetched the share a third time.
+`ShareStoragePort::increment_access_count` is now one
+`UPDATE … SET access_count = access_count + 1 WHERE token = $1 AND <expiry>`:
+**3 subquery round-trips → 2** for the landing (register + fetch), no
+read-modify-write race, no collateral column rewrites.
+
+## 5. Trash — dead SELECT removed
+
+`TrashService::move_to_trash` fetched the full file/folder entity to build a
+`TrashedItem` consumed only by `TrashRepository::add_to_trash` — a documented
+no-op in the soft-delete model. Both branches now go straight to the
+`move_to_trash` UPDATE: **one uncached SELECT + entity hydration removed per
+trash operation** (file and folder).
+
+## 6. NFC normalization fast path
+
+`normalize_storage_name` ran unicode-normalization's full
+decompose/recompose state machine on every name of every row loaded from PG
+(listings, PROPFIND, photos — 27 constructor call sites), even though the DB
+invariant guarantees stored names are already NFC. `is_nfc_quick` (a
+per-char table lookup) now short-circuits the ~100 % case to a plain copy;
+`Maybe`/`No` still run the full pipeline, so semantics are unchanged.
+
+## 7. Frontend — first-page render for large folders
+
+`fetchFolderListing` paged the ENTIRE folder (sequential 200-item requests)
+before returning anything — a 2,000-item folder waited ~10 round-trips
+before first paint. The files route now paints page one immediately via the
+new `onPage` hook and fills in as later pages land (skipped when a cached
+listing is already on screen, so views never shrink). First-paint latency
+for an N-item folder drops from ⌈N/200⌉ sequential RTTs to 1.
+
+## Refuted by benchmark (reverted, kept for the record)
+
+- **Cached `Intl.Collator` for name sorts (frontend):** sorting 5,000 names —
+  argument-less `localeCompare` 5.6 ms vs cached collator **12.1 ms (2×
+  slower)**. V8 fast-paths argument-less `localeCompare`; the "cache the
+  collator" folklore does not apply. Reverted, ordering untouched.

+# PROPFIND folder paging — keyset cursor + (folder_id, name) index
+
+`list_files_batch` walks a folder's children in name order, 500 per page
+(native + NextCloud PROPFIND streamers). The old shape was `ORDER BY name
+LIMIT 500 OFFSET k` with **no supporting index** — the initial schema's
+`(folder_id, name, user_id)` index that served it was dropped by migration
+20260902000000 (user_id → nullable), leaving only `idx_files_folder_id`. So
+every page bitmap-scanned all N children and top-sorted them: a full listing
+of an N-file folder cost O(N²/500) row visits + ⌈N/500⌉ sorts.
+
+Changes:
+
+1. Migration `20260917000000_files_folder_name_index.sql`: partial composite
+   `idx_files_folder_name (folder_id, name) WHERE NOT is_trashed`.
+2. `list_files_batch` cursor switched from OFFSET to keyset
+   (`name > $last`, names are unique per folder via the
+   `(drive_id, folder_id, name)` unique index) across the port trait, the
+   repository and both handler loops. The cursor predicate is only emitted
+   when a cursor exists — a `$2 IS NULL OR …` disjunction would block the
+   index condition under the extended protocol's generic plans.

+- Full-folder listing cost drops **16.5×**; unlike OFFSET (even indexed),
+  keyset stays O(page) at any depth, so the gap widens with folder size.
+- Companion fix in the same commit: the Photos timeline cursor
+  (`list_media_files`) wrapped its keyset column in
+  `EXTRACT(EPOCH FROM …)::bigint` plus an `IS NULL OR` disjunction —
+  non-sargable, so page k re-scanned all k·limit rows already scrolled past.
+  It now compares the raw `media_sort_date` against a timestamptz bind
+  (identical row semantics — the cursor is whole seconds) and splits the
+  cursor/no-cursor query shapes, restoring the
+  `idx_files_media_timeline_by_drive` boundary condition the index was built
+  for. Same mechanism as measured above (index-boundary vs per-row filter);

+# Quota path — narrow 2-column read + skip-when-not-requested
+
+Two independent fixes on the quota resolution that runs on every upload check
+and every quota-reporting folder PROPFIND:
+
+1. **Narrow read.** `check_storage_quota` / `get_user_storage_info` called
+   `get_user_by_id`, whose SELECT drags the entire `auth.users` row —
+   including `image`, an avatar data URI of up to 512 KiB — to read two i64s.
+   New `UserPgRepository::get_storage_usage` reads exactly
+   `(storage_used_bytes, storage_quota_bytes)` (same pattern as the existing
+   `get_user_flags`).
+2. **Skip entirely when not asked.** `resolve_webdav_quota` (2 round-trips:
+   drive row + user row) ran on EVERY folder PROPFIND on both surfaces, even
+   when the client's `<D:prop>` list named no quota property — which is the
+   common shape for sync-client polls. `PropFindRequest::wants_quota()` now
+   gates it: `AllProp`/`PropName` keep quota (the writers emit RFC 4331 props
+   there), explicit prop lists trigger the lookups only if they name
+   `quota-used-bytes` / `quota-available-bytes`. Responses are byte-identical
+   for every request that names quota or asks for allprop.
+
+## Reproduce

+SLOWER than `to_string()` and were rewritten (§13) before adoption, and the

+
+## [1][2] Auth hot path — the ROUND6/9 deferred "cheapest known win"
+
+Every authenticated request built `CurrentUser` by deep-cloning
+`username`/`email` out of the cached `Arc<TokenClaims>` and `to_string`ing
+the live role — the exact 2-allocs-per-request item deferred since ROUND6,
+plus two more nobody had counted (`flags.role.to_string()` in
+`decide_live_role`, and the Basic-auth cache handing out 3 owned Strings
+per moka hit on every DAV request).
+
+Now: `TokenClaims.username/email` are `Arc<str>` (serde `rc`, same one
+allocation at decode time), `CurrentUser.username/email` are `Arc<str>`
+(refcount bumps), `CurrentUser.role` is an inline `SmolStr` fed by
+`LiveRole::Active(SmolStr)` + the new `UserRole::as_str()` (`&'static`,
+zero alloc), and `CachedBasicAuthResult` carries the same types so a
+Basic hit is bumps + a 24-byte memcpy. JSON wire shape is unchanged
+(byte-identity gated); OpenAPI keeps `String` via `value_type`.
+
+```
+cargo run --release --features bench --example bench_round10_micro
+# [1] identity build  BEFORE 77.2 ns / 4.00 allocs → AFTER 59.0 / 1.00
+#     gate: fields + serialized JSON byte-identical
+# [2] basic-auth hit  BEFORE 62.2 ns / 3.00 allocs → AFTER 40.9 / 0.00
+```
+
+The JWT service also stopped rebuilding `EncodingKey`/`DecodingKey`/
+`Validation` per call (now fields; the verify-miss path drops 4 allocs,
+§15), and `generate_access_token`'s `format!("{}", role)` became
+`as_str().to_string()`.
+
+## [3] Share download — the handler already had the DTO
+
+`serve_share_file` fetched the file DTO for ETag/Range handling, then
+called `get_file_optimized`, which re-ran the same metadata query. The
+authenticated download path already used `get_file_optimized_preloaded`;
+the public-share path now does too (the DTO is moved, not cloned — the
+one later use of `size` is captured first).
+
+```
+cargo run --release --features bench --example bench_round10_queries
+# [1] BEFORE 2 queries 0.700 ms/download → AFTER 1 query 0.321 ms (2.18x)
+```
+
+## [4] Contact-group summary — 500 vCards hydrated to compute `len()`
+
+`get_group` called `get_contacts_in_group` — full rows (vCard TEXT that
+can carry base64 photos + 3 JSONB arrays parsed per contact) — and kept
+only the count. New `count_contacts_in_group` port method backed by
+`SELECT COUNT(*)` on `group_memberships`.
+
+```
+# [3] 500 members: BEFORE hydrate-all 5.762 ms → AFTER COUNT(*) 0.387 (14.9x)
+```
+
+## [5][6] Write-path N+1 loops → one UNNEST statement
+
+- `save_faces`: one INSERT per face inside a transaction → a single
+  multi-row `INSERT … SELECT FROM unnest(...)` (the `bbox` float4[] rides
+  as 4 parallel component arrays, reassembled server-side). 30-face image:
+  5.90 → 1.52 ms (**3.9x**); gate re-reads a stored row field-by-field.
+- `reorder_items`: one autocommit UPDATE per track (non-atomic — a
+  mid-loop failure left a half-applied order) → one
+  `UPDATE … FROM unnest($1) WITH ORDINALITY`. 500-track reorder:
+  167.0 → 2.6 ms (**63.7x**); gate compares every final position.
+
+## [7][8] Independent awaits overlapped (`join!`, decide-by-bench)
+
+- `SearchService::search` awaited the content-index lookup, the file page
+  and the folder query serially in both branches; `suggest_with_perms` had
+  the correct shape since ROUND4. All three are independent; the two SQL
+  arms measured 4.16 → 2.87 ms (**1.45x**) with identical results.
+  (Content-index enabled widens the win — the Tantivy arm is the long pole
+  and now overlaps both queries.)
+- File/folder move pre-check ran the source-drive-policies and
+  destination-drive point reads serially before comparing:
+  0.664 → 0.311 ms (**2.14x**). Adopted per the ROUND6 protocol (these are
+  two independent point reads whose server-side execution parallelizes —
+  the shape that wins even on a local socket).
+- The NC PROPFIND folder-HEADER trio (favorites + oc:fileid + dead props
+  for the folder's own entry, on the TTFB critical path of every folder
+  PROPFIND) got the same `join!` ROUND9 gave the per-page child triples.
+
+## [9] Trash listing — the dropped-index gap
+
+Migration 20260904 removed `user_id` and with it the only trash-listing
+index; what remained forced either a live-rows scan of the drive
+(`idx_files_drive_id`) or an all-tenants trash scan
+(`idx_files_trash_expiry`). New partial pair
+`(drive_id, trashed_at) WHERE is_trashed` (migration 20260920000000)
+bounds the read to the caller's drives' trashed rows, pre-ordered for the
+`trashed_at`/`deletion_date` keysets. On a 30-drive box (3 000 live + 25
+trashed each): 0.615 → 0.496 ms (**1.2x**); the gap widens with drive size
+since the BEFORE plan scans live rows. Identical row sets gated; the
+retention sweeper keeps its global expiry index.
+
+## [10][11] Cold-album herd — parent batching + cascade single-flight
+
+ROUND9 §10 left the cold first view paying one parent PK read per photo
+and noted batching "needs a wider engine API". It doesn't: the browser
+fires its thumbnail requests near-simultaneously, so the batching can live
+INSIDE `file_parent_folder_cached`:
+
+- **Leader-inline protocol** (`parent_batch` slot): an idle miss marks
+  itself leader (one mutex op) and runs its point query exactly as before
+  — the sequential path is unchanged (a channel-task design measured
+  ~66 µs/miss of hop overhead and was REJECTED). Misses arriving while
+  the leader is in flight park a oneshot; the leader serves them all with
+  ONE `id = ANY($1)` charity batch after its own read; a second wave is
+  handed to a detached drainer so the leader's response is never delayed
+  by more than one batch. A cancelled leader's guard wakes every parked
+  waiter to re-elect; waiters that exhaust retries fall back to the
+  inline point read. Requested-but-absent ids memoise as `None`,
+  matching the point read's semantics.
+- **`cascade_grant_cached` → `try_get_with`** (the ROUND3 auth-herd
+  pattern): K concurrent files of one album all recurse into the SAME
+  folder decision; get→compute→insert let each run the ltree query.
+  Single-flight collapses that to one loader; moka never caches loader
+  errors, preserving error semantics.
+
+```
+cargo run --release --features bench --example bench_thumbnail_cascade_cache
+# thumbs=100 (folder-grant recipient, no drive membership)
+# ROUND8 cold (union/file)      65.59 ms   655.90 µs/thumb
+# AFTER cold sequential         65.53 ms   655.33 µs/thumb  (parity — no
+#   sequential regression from the protocol; this box's high per-query
+#   latency compresses the R9 decomposition margin visible on faster I/O)
+# AFTER warm (revalidation)      0.14 ms     1.42 µs/thumb  (unchanged)
+# AFTER herd (concurrent cold)  35.35 ms   353.47 µs/thumb  (~1.9x vs
+#   sequential cold — and the real shape of a grid's first view)
+#   parent queries for the herd: 2   (was 100)
+# gates: all original ROUND8/9 safety gates (outsider denied, clear_role
+#   revoke denies immediately, direct-grant sibling isolation) plus NEW:
+#   herd answers == point-read answers per file, parent queries < K/4
+```
+
+## [12] NC preview + avatar — ETag existed, nobody compared it
+
+- `/index.php/core/preview` set an immutable ETag but never read
+  `If-None-Match` — every gallery revalidation re-ran NC-id resolve, file
+  fetch, authz, blob-hash query, thumbnail cache read and full body. The
+  handler now answers 304 right after the authz check (never before it).
+- `/index.php/avatar/{user}/{size}` had no ETag at all, and re-decoded the
+  stored data URI on every request (for WebP avatars: a full image decode
+  + PNG encode per request). Now: content-hash ETag (over the stored URI,
+  computed before any decode), 304 on match, and the WebP→PNG transcode
+  memoised in a 32-entry moka keyed by content hash.
+
+End-to-end (real server + curl loops, the PHOTOS-ETAG methodology; 60
+requests per arm):
+
+```
+# preview  200: 5 004 bytes/req  1.35 ms   →  304: 0 bytes  1.25 ms
+# avatar   200: 196 992 bytes/req 2.30 ms  →  304: 0 bytes  1.97 ms
+# gates: fresh GET 200 with ETag; matching If-None-Match → 304 empty;
+#        stale If-None-Match → full 200. All six pass.
+```
+
+Per NC client per cache-lapse this removes ~197 KB (avatar) + ~5 KB/photo
+(previews) of transfer plus the per-request DB/disk work behind them.
+
+## [13] `common::fmt` — the bench caught our own helpers losing
+
+The round's first micro run showed the PROPFIND int-field port SLOWER on
+wall despite 1 500 fewer allocs. An isolated interleaved probe confirmed:
+the byte-at-a-time div-by-10 loop in `u64_str` (33.7 ns) lost to
+`u64::to_string()` (22.5 ns) — std renders via a 2-digit lookup table.
+Rewrote `u64_str`/`i64_str` (and the date helpers' `push2`) on the same
+`DEC_LUT` technique, dropping `i64_str`'s temp-buffer copy:
+
+```
+# interleaved probe, 20M ops/arm
+# to_string 22.5 ns   i64_str BEFORE 33.7 ns → AFTER 16.1 ns
+# to_rfc2822 42.7 ns  rfc2822_utc 33.6 ns
+```
+
+This speeds every existing ROUND4-9 call site (`d:getcontentlength`,
+`oc:size`, digest lengths, dates) as well as the new ones.
+
+## [14] NC PROPFIND / trashbin emit stragglers
+
+With §13 in place, the remaining `to_string()`/`to_rfc2822()` fields moved
+to the stack helpers: `oc:fileid`, `nc:creation_time`, `nc:upload_time`,
+quota bytes (files + folders writers), and the trashbin's per-item
+modified/deletion-time/fileid (which still ran the chrono interpreter).
+
+```
+# [3] 500-row page  BEFORE 95.5 µs / 1501 allocs → AFTER 86.3 / 1   (1.11x)
+# [4] 2000-item bin BEFORE 318.5 µs / 4002 allocs → AFTER 280.7 / 2 (1.13x)
+# gates: XML byte-identical in both harnesses
+```
+
+## [15] Micro-pack (each gated in `bench_round10_micro`)
+
+- **WebDAV scope probe**: `format!("{prefix}/")` per request → borrow-only
+  `strip_prefix` pair. 38 → 3.5 ns, 1 → 0 allocs, identical routing.
+- **`ShareService.base_url`**: `env::var("OXICLOUD_BASE_URL")` + rebuild
+  PER DTO ROW → constructor snapshot. 500-row listing: 71.5 µs → 1 ns.
+- **`cookie_secure`**: 4 env-var resolutions + duplicate SECURITY log
+  lines per login → `OnceLock` (process-invariant by definition).
+- **JWT verify miss**: fresh `Validation` + `DecodingKey` per decode →
+  service fields. 4 748 → 4 527 ns, 17 → 13 allocs (HMAC dominates).
+- **`EncryptedBlobBackend`**: per-op clone of the expanded AES-256 round
+  keys → `Arc` bump. 30.8 → 13.3 ns per hand-off.
+- **Request-id header**: `Uuid::to_string` + `HeaderValue::from_str` →
+  stack-encode. 85 → 46 ns, 2 → 1 allocs, identical bytes.
+- **NC chunk PUT**: the retry-detection `stat` per chunk folded into the
+  open — `stream_body_to_path` now opens `create_new` first and reports
+  `created_fresh` (AlreadyExists → truncate-open), the ROUND9 §5a pattern
+  applied to the NC surface.
+
+## [16] CalDAV update/delete gate — narrow `calendar_id` read
+
+The service fetched the FULL event row (with `ical_data` — 11 KB in the
+benched shape, unbounded with attendees/VALARMs) only to read
+`.calendar_id` for the authz gate. New `find_calendar_id_by_event_id`
+scalar. 0.323 → 0.308 ms on a local socket (1.05x) — adopted for the
+direction: the win is the row width off the wire, which grows with event
+size and network distance. (This is NOT the deferred authz-reorder — the
+gate still runs before the mutation, same order.)
+
+## [17] Legacy favorites/recents rows — the ROUND6 §10 port, with a catch
+
+The two legacy listing methods still shipped `::TEXT` casts. Porting them
+to binary decode surfaced that `auth.user_favorites.id` is a SERIAL
+`integer`, not a UUID — the bench's identity gate caught the wrong decode
+before it could ship (decode as `i32`, render app-side). 500-row page:
+2.80 → 2.58 ms (**1.09x**), rendered tuples identical.
+
+## [18][19][20] SPA pack (vitest gates)
+
+```
+cd frontend && npx vitest run src/routes/search/staleGuard.bench.test.ts \
+  src/lib/api/endpoints/folderDedup.bench.test.ts src/lib/utils/grid.bench.test.ts
+```
+
+- **Search stale-response guard** (the flag open since ROUND7): rapid-fire
+  query/sort/filter changes had no seq token and no abort — a slow older
+  response could clobber a newer one, and superseded recursive searches
+  ran to completion server-side. `run()` now carries a sequence token +
+  `AbortController` (threaded through `searchFiles`/`searchSuggest`);
+  AppShell's suggest box got the same guard. 10-query burst: completed
+  round-trips 10 → 1; final result provably fresh (BEFORE ends on the
+  STALE query).
+- **`getFolder` in-flight dedup** (the `resolveUser` pattern): cold
+  deep-links fired the same folder-metadata GET twice (breadcrumbs +
+  drive-id resolver). Concurrent duplicates now share one request;
+  sequential calls still refetch (freshness unchanged, gated).
+- **`gridColumns`**: a fresh `matchMedia` (style read) per call inside the
+  grid windowing derives → one module-level MQL fed by its `change`
+  listener (the photos-timeline fix applied to the shared util). 10k
+  calls: 10 000 → 0 MQL constructions, 13.4 → 2.6 ms; output identity
+  gated across the breakpoint, crossings propagate via the listener.
+
+## Rejected / reworked this round (the discipline working)
+
+- **Channel-task parent batcher**: correct, but the mpsc+oneshot
+  round-trip measured 65.9 µs per sequential miss — a pure regression for
+  the non-concurrent case. Replaced with leader-inline (§10).
+- **First stack-formatter port**: slower than `to_string()` on wall
+  (§13); adopted only after the LUT rewrite made it faster on BOTH axes.
+- **`uf.id` as binary UUID**: wrong type entirely (SERIAL int) — the
+  equivalence gate caught it; shipped as `i32` decode instead.
+
+## Deferred / flagged (not shipped this round)
+
+- **CalDAV authz-before-fetch reorder** — still awaiting maintainer
+  sign-off per the authz-change convention (ROUND9 flag stands).
+- **Grouped file/grid views are unvirtualized** (files group-by and
+  ResourceList grid sections mount every row; the flat/list paths are
+  windowed) — a UI-behaviour change big enough to want its own pass.
+- **`search_files_paginated`'s `COUNT(*) OVER()` + OFFSET** — keyset would
+  change the API's total-count contract; needs a product decision on
+  whether search totals can become approximate/capped.
+- **`ResourceList.selectedEntries`** recomputes an O(N) filter per
+  selection toggle once the toolbar is visible; hosts often shadow it
+  with their own copy. Needs a small API rework (getter or id-index).
+- **Chunk-upload `progress.bin`** full rewrite per chunk (REST surface) —
+  debouncing trades crash-resume granularity; flagged for discussion.
+- **`CachedBlobBackend::local_blob_path`** sync `stat` on the reactor
+  (remote-backend deployments' media hooks) — needs an async variant of
+  the port method; low urgency.

+# Round 11 — StoragePath re-representation, classifier fusion, memoized static bodies, query-shape pack, SPA fine-grained stars
+
+Benchmark-gated, same rule as ROUND2-10: every change ships with a
+BEFORE/AFTER benchmark and an equivalence/safety gate; an AFTER that doesn't
+beat its BEFORE gets rolled back or redesigned. Four candidates went through
+exactly that loop this round (§Rejected below): the moka `and_upsert_with`
+rate-limiter rewrite, the GET/HEAD `Last-Modified` stack-render port, the
+`min(uuid)` geo-cluster cast (PostgreSQL has no such aggregate — the gate
+caught it before it could ship broken), and the `tracing-appender`
+non-blocking log writer (slower than sync on fast sinks, tail-loss risk on
+slow ones).
+
+Measured on 4 cores / 15 GiB, local PostgreSQL 16 (fsync off), release
+profile; frontend on Node 22 / vitest 4 (jsdom). Reproduce any row with the
+command in its section (`benches/ROUND11.md` §Environment).

+
+Also shipped without a dedicated row: CardDAV `getlastmodified` per-contact
+stack render (ROUND10-§13 helper + chrono fallback), NC capabilities poll
+logs demoted to `debug` (each poll forced a formatted line + locked stdout
+write), trash `to_dto` `into_parts` move + fused/interned display fields
+(trash listing and path-resolver rows now share the ROUND9 interning),
+`TrashedItemDto` name/path moves.
+
+Cross-round regression guards re-run after the StoragePath / classifier
+rework — both gates PASS byte-identical, and the shipped code now beats the
+numbers those rounds recorded:
+
+- `bench_row_path` (round 4): file row 705 → 280 ns/row (2.52x), allocs
+  15.75 → 6.00; folder row 684 → 365 ns (1.87x), 14.08 → 5.24.
+- `bench_dto_map` (round 3): File→FileDto 839 → 606 ns/row, 10.09 → 3.08
+  allocs; Folder→FolderDto 314 → 161 ns, 11.80 → 1.00 allocs.
+
+## [1] REST download dead clone → move
+
+```
+cargo run --release --features bench --example bench_round11_micro   # §1
+```
+
+`download_file_impl` cloned the whole `FileDto` (7 owned Strings) into
+`get_file_optimized_preloaded` on every authenticated download, purely to
+read `mime_type`/`size` afterwards — the share path already captured+moved
+(ROUND10 §3 fixed its double-*fetch*, not this clone). Now: one `Arc<str>`
+bump + a `u64` copy, then move. 295.3 → 20.7 ns, 7 → 0 allocs per download.
+
+## [2] StoragePath joined-only representation
+
+```
+cargo run --release --features bench --example bench_round11_micro   # §20
+cargo run --release --features bench --example bench_row_path        # cross-round gate
+```
+
+`StoragePath` stored `segments: Vec<String>` — one heap String per path
+component built on EVERY hydrated row — while the DTO path only ever
+consumed the joined form, and the entities carried a second `path_string`
+duplicate. The value object now stores the canonical joined `String` alone
+(`"/"` or `/seg(/seg)*`); `file_name`/`parent`/`segments()`/`Display`
+derive on demand; `File`/`Folder` lost the duplicate field (`path_string()`
+borrows). `.segments()` had zero external callers — verified before the
+rework. Equivalence gates: identical `path_string`, `file_name`, `parent`,
+`Display` across the corpus, plus the round-4 harness's byte-identical
+gate. 500-row page: 121.0 → 80.3 µs, 4 000 → 1 000 allocs; per-row RAM
+drops by the Vec + per-segment String headers + the duplicate path.
+
+## [3] Display classifier fusion
+
+```
+cargo run --release --features bench --example bench_round11_micro   # §21
+```
+
+Every listed file ran the full MIME classification three times
+(`icon_class_for`, `icon_special_class_for`, `category_for`), each
+heap-allocating its own `to_ascii_lowercase()` on the extension-fallback
+path. The three decision trees are byte-for-byte preserved (they diverge
+deliberately, so no merged tree); `classify_display` lowers the extension
+once into a 16-byte stack buffer shared by all three. Extensions longer
+than any table entry short-circuit to the same `_`-arm defaults (gated).
+Call sites: `FileDto::from`, folder/favorites/recent handlers, trash
+listing (×2), path-resolver — the last two also gained the ROUND9
+interning they had missed (`Arc::from` per row → refcount bump).
+13-row corpus: 4 390 → 2 074 ns, 21 → 0 allocs.
+
+## [4][5] Memoized process-invariant bodies
+
+```
+cargo run --release --features bench --example bench_round11_micro   # §3, §18
+```
+
+`/status.php` rebuilt its `json!` tree per NC client poll (836 ns / 14
+allocs → 28.8 ns / 0). `/openapi.json` was the extreme case: utoipa
+reconstructed and re-serialized the whole 171 KiB spec on every request —
+2.77 ms / 12 474 allocs → 18.5 ns / 0 via the same `OnceLock<Bytes>`
+pattern as ROUND9's capabilities memoization. Byte-identical gates on both.
+
+## [6] NC upload-session PROPFIND emit
+
+The last hand-built XML handler: `String::new()` + `push_str(&format!(…))`
+per element per chunk + chrono `to_rfc2822()` per chunk. Now pre-sized +
+`write!` + `common::fmt::rfc2822_utc` (chrono fallback out-of-range).
+Byte-identical gates at 16 and 256 chunks (escape distributes over
+concatenation; RFC 2822 output has no XML-special chars). 16 chunks:
+13.2 → 5.2 µs; 256 chunks: 203.7 → 75.4 µs, 2 582 → 772 allocs.
+
+## [Q1] Deferred upload registration 3 → 1
+
+```
+cargo run --release --features bench --example bench_round11_queries # §1
+```
+
+The write-behind REST upload path ran parent-drive SELECT → INSERT →
+parent-path SELECT, the first and third re-reading the identical
+`storage.folders` row. Ported to the `WITH parent AS (…) INSERT … SELECT
+… RETURNING (SELECT path FROM parent)` template `persist_file` has used
+since ROUND2 — 0 rows ⇒ the same `not_found("Folder")` the old first query
+produced (gated, anti-enum shape preserved). Root uploads (no parent)
+keep their previous two-step shape.
+
+## [Q2] direct_grant_cache
+
+Calendar/AddressBook/Playlist were the only `check()` arms with no result
+cache — every CalDAV/CardDAV/music request re-ran the `role_grants` point
+query, and DAV clients poll continuously. Added
+`direct_grant_cache: Cache<(Subject, Resource, Permission), bool>`
+(30 s TTL / 100k, `try_get_with` single-flight — the ROUND8/10 pattern),
+flushed on `set_role`/`clear_role` for those resource types; group/expiry
+churn self-heals within the TTL exactly like `cascade_grant_cache`.
+Gates: identical verdict; a revocation + flush flips the next check.
+0.197 ms → 0.2 µs on hit.
+
+## [Q3] expand_user join!
+
+The `is_external` point read and the recursive groups CTE are independent;
+serial await paid two round-trips end-to-end on every cold expansion
+(per user per 30 s TTL window). `tokio::join!`: 0.426 → 0.204 ms.
+
+## [Q5] Recluster UNNEST batch
+
+`POST /api/people/recluster` issued one `UPDATE faces.faces SET person_id`
+per face sequentially (both the unassign-small-clusters and assign loops).
+Assignments now accumulate and apply as a single
+`UPDATE … FROM unnest($1::uuid[], $2::uuid[])` (the ROUND10 `save_faces`
+pattern) — 200-face library: 80.0 → 8.7 ms, final column state identical.
+Pairs with §18's norm precomputation on the CPU side (7.70 → 7.17 ms for
+the O(N²) pass, bit-identical similarity gated over every pair).
+
+## [S1][S2][S3] SPA pack (vitest gates)
+
+```
+cd frontend && npx vitest run src/lib/components/round11.bench.test.ts
+```
+
+- **`ResourceList.selectedEntries`** (the ROUND10 flagged item): the
+  component re-filtered the ENTIRE items array per selection change, and
+  favorites/recent ignored the snippet param and recomputed their own
+  `entries.filter(…)` shadow — two full O(N) scans per toggle, O(N²)-ish
+  across a shift-range. Now an id→index Map (rebuilt only when `items`
+  changes) projects the selection in O(k·log k) preserving item order;
+  hosts consume the snippet param and their dead `selectedIds` mirror is
+  gone (the component's prune effect already self-heals on reload).
+  51-toggle gesture on 2 000 items: 204 000 → <2 602 comparisons.
+- **Recent favorite star**: the entry mapper read `favoriteIds.has(id)`,
+  subscribing the whole O(N) map to the SvelteSet — one star click rebuilt
+  all N entries and re-rendered every visible row. `ResourceList` gained a
+  `favoriteIds` prop read directly by the star widget; the mapper is
+  set-independent. Star click: N → 0 rows re-mapped, star states gated
+  identical.
+- **admin `timeAgo`**: the >30-day fallback called `toLocaleDateString()`
+  (a fresh `Intl.DateTimeFormat` per call); now the app-wide cached
+  formatter — output equality gated, ≤1 construction per 1 000 formats.
+
+## Rejected / reworked this round (the discipline working)
+
+- **`min(fm.file_id)::text` geo-cluster cast (Q4)**: PostgreSQL has **no
+  `min(uuid)` aggregate** — the "cast once per cluster" rewrite fails to
+  parse (`42883`). The gate caught it before it could ship broken; the
+  per-row-cast original stays (22.6 ms per 5k-row viewport, admin-shaped
+  traffic), and a custom `CREATE AGGREGATE` was judged schema surface this
+  query doesn't justify. The bench section now reproduces the rejection.
+- **RateLimiter `entry().and_upsert_with`**: 1 657 → 2 365 ns and
+  8.0 → 9.1 allocs — moka's compute-entry machinery costs more than the
+  two ops it replaced. Redesigned as lock-free `get` (borrows the key, no
+  alloc) + `insert`: 6.0 allocs, wall within variance; identical counter
+  sequence gated. Adopted in that form.
+- **GET/HEAD `Last-Modified` stack-render port**: chrono's `to_rfc2822()`
+  String IS the terminal allocation the header needs (38.7 ns incl. alloc
+  vs 47.0 ns stack render + the same alloc). Only body-emit sites (where
+  `write!` lands in an existing buffer, 31.8 ns / 0 allocs) benefit —
+  those were ported (§6 + CardDAV); header sites stay on chrono.
+- **`tracing-appender` non-blocking log writer (L1)**: on a fast sink
+  (stdout→/dev/null — the containerized default) sync sustains 1.41M ev/s
+  vs 0.99M non-blocking, with a better tail (p999 76 vs 151 µs, max 0.8
+  vs 8.3 ms — the channel hop costs more than the write). Non-blocking
+  only wins on a slow sink (20 µs/line: 6.4x wall, p50 22 → 1.9 µs), but
+  there the drain gate FAILED — buffered tail lines can be lost at
+  shutdown, unacceptable for the audit channel. Not adopted;
+  `tracing-appender` stays as a dev-dependency for the reproducible
+  harness (`bench_log_writer`, 4 arms via `BENCH_LOG_ARM`/`_WRITER`).
+- **First search-page model (`drain(range)`)**: −300 allocs but slower on
+  wall (tail memmove). Reshaped as `into_iter().skip().take().collect()`
+  — moves the page, drops the rest, wins both axes (§12 row in Summary).
+
+## Deferred / flagged (not shipped this round)
+
+- **NC preview 304 still runs `get_file`**: dropping the fetch on the
+  revalidation path changes existence semantics (deleted file → 304
+  instead of 404) — needs maintainer sign-off, same class as the standing
+  CalDAV authz-before-fetch reorder (ROUND9/10 flag).
+- **`CachedBlobBackend`'s `Mutex<LruCache>` index** serializes every
+  cached read on remote+cache deployments; the moka byte-weigher
+  migration (file-content-cache pattern) deserves its own round with a
+  concurrency bench and eviction-unlink care.
+- **Capture-metadata extraction reads each media file 2-3×**
+  (`media_metadata_service`: kamadak full read + nom-exif path re-read +
+  track fallback). Feeding nom-exif from the in-memory buffer needs its
+  `MediaSource` API verified on the pinned version.
+- **`CachedBlobBackend::local_blob_path` sync `stat`** (ROUND10 flag
+  stands — needs an async port variant).
+- **Azure SDK 0.21 stack** drags duplicate dependency trees (h2 0.3+0.4,
+  three hashbrown generations, base64 0.13, getrandom 0.1) into every
+  build — an SDK bump is a dedicated migration.
+- **`AudioMetadataRepository::list_by_{artist,album,genre}`** are dead
+  code with seq-scan `ILIKE` shapes — flag for deletion, not indexing.
+- **`CachedBlobBackend::put_blob` cache population** silently fails for
+  S3/Azure whole-file puts (inner backend deletes the source before the
+  cache copy) — correctness note for maintainers.
+- **Grouped file/grid views unvirtualized** (ROUND10 flag stands).
+
+## Environment / methodology

+# Round 12 — auth write-path narrowing, fused quota gate, moka blob-cache index, media single-read, sized listing JSON

+BEFORE/AFTER benchmark and an equivalence/safety gate; an AFTER that doesn't
+beat its BEFORE gets rolled back or redesigned. One candidate went through
+exactly that loop this round (§Rejected): the single-pass compression
+predicate — the profiler-plausible "28 redundant Content-Type reads" turned
+out to cost ~4.6 ns TOTAL once monomorphized, and the fused replacement
+measured within noise, so the declarative chain stays.
+

+profile; frontend on Node 22 / vitest 4. Reproduce any row with the command
+in its section.
+
+## Summary
+
+| # | change | key metric | before → after |
+|--:|---|---|---|
+| Q1 | NC sharee search: username-only projection (was 21 wide columns incl. the ≤512 KiB avatar per match) | 26-row page, 3 000 users, all matches avatared | 11.77 → 2.37 ms (**4.98x**) |
+| Q1b | + `gin_trgm_ops` indexes on `auth.users` (migration 20260719000000) | same page, leading-wildcard ILIKE | → 0.215 ms (**54.7x** total) |
+| Q2 | Password login: redundant full-row `update_user` deleted (`create_session` already stamps `last_login_at`) | ms/login, 256 KiB avatar | 2.96 → 0.67 (**4.45x**) · −1 txn, −17-column rewrite, −512 KiB clone |
+| Q3 | Email-verified stamp → narrow conditional UPDATE (magic-link) | ms/stamp | 2.20 → 0.25 (**8.9x**) |
+| Q3b | OIDC repeat login → in-memory compare, sync only on change | queries per repeat login | full-row rewrite (2.37 ms) → **0 queries** |
+| Q4 | Refresh-token rotation: 2 transactions → 1 (`rotate_session`) | ms/rotation | 1.135 → 0.959 (**1.18x**) |
+| Q5 | WOPI CheckFileInfo triple → `tokio::join!` (real `PgAclEngine`) | ms/call | cold 0.485 → 0.363 (**1.34x**) · warm 0.228 → 0.209 |
+| Q6 | Upload quota pair → ONE fused read (user envelope + drive cap) — NC chunk PUT pays it per chunk | ms/check | 0.350 → 0.193 (**1.81x**) · 2 → 1 queries/chunk |
+| M1 | Listing JSON: pre-sized buffer (`sized_json`) vs axum `Json`'s 128 B seed | 500-row page | 282.4 → 201.0 µs (**1.40x**) · 13 → 2 allocs |

+| M5 | Chunked-upload session ops: 5 → 3 map lookups + stack-encoded uuid compare | ns per chunk (prepare+commit) | 469 → 366 (**1.28x**) · −2 allocs |
+| B1 | Blob-cache index: `Mutex<LruCache>` → moka byte-weigher | pure index probes, K readers | K=2 **2.17x**, K=4 1.61x, K=8 1.46x (mutex scaled NEGATIVELY: 2.08 → 1.07 Mops/s from 1 → 2 readers) |
+| B2 | `put_blob` populates the cache BEFORE the inner backend consumes the source (was: after → failed 100%) | first read after whole-file put | full remote re-download → local hit |
+| F1 | SPA list view: 150 px `icon` thumbnails (was 400 px `preview` into a 40 px slot) | pixels per list thumbnail | **~7.1x fewer** (≈4-5x fewer bytes) |
+
+## [Q1] NC sharee search — the 512 KiB-per-row autocomplete
+
+```
+cargo run --release --features bench --example bench_round12_queries   # §1
+```
+
+`handle_sharees_search` fired `search_users` per keystroke — the full
+21-column row (incl. the ≤512 KiB avatar data-URI `image`, TOAST-detoasted
+per match) hydrated into `User` → `UserDto`, of which the handler read ONLY
+`username`. And the leading-wildcard `ILIKE '%q%'` had no trigram index, so
+every keystroke seq-scanned `auth.users` (contacts/files/folders all have
+`gin_trgm_ops`; users was the gap). Now: `search_usernames` port method
+(same WHERE/ORDER/LIMIT, username-only projection; NULL usernames filtered
+app-side exactly like the wide flow's post-limit filter) + the two trgm
+indexes. Gates: identical username lists, with and without the indexes.
+The wide method stays for the admin table (which serializes `image`).
+
+## [Q2][Q3][Q3b] Auth write-path narrowing
+
+```
+cargo run --release --features bench --example bench_round12_queries   # §2-3
+```
+
+- **Login** ran `update_user(user.clone())` — a transaction rewriting all
+  17 columns (incl. the avatar, plus a 512 KiB deep clone to feed it) —
+  purely to persist `last_login_at`… which `create_session` overwrites in
+  its own transaction three lines later. Nothing reads the row in between
+  (verified). The call is deleted; the in-memory `register_login()` stays
+  so the response DTO carries the timestamp.
+- **Magic-link redemption** kept its `update_user` for the email-verified
+  stamp only (last-login again covered by `create_session`) — now a narrow
+  `WHERE … AND email_verified_at IS NULL` single-column UPDATE, idempotency
+  moved into SQL (gated: second stamp is a 0-row no-op, first timestamp
+  preserved).
+- **OIDC repeat login** additionally syncs the IdP avatar. The row fetched
+  by `get_user_by_oidc_subject` already carries the stored avatar +
+  verification stamp, so the service now compares IN MEMORY and issues NO
+  query at all on the repeat-login common case (same picture, already
+  verified) — the bench's §3b arm is the reason: even a guarded
+  `IS DISTINCT FROM` no-op UPDATE ships the ≤512 KiB avatar parameter over
+  the wire just to compare it (1.20 ms vs the 2.37 ms full-row rewrite;
+  the in-memory skip makes it 0). When something DID change,
+  `sync_oidc_login_profile` runs the guarded narrow UPDATE (image +
+  conditional stamp, `update_storage_usage` pattern) instead of the
+  17-column rewrite.
+
+## [Q4] Refresh rotation — one transaction
+
+`refresh_token` paid two full BEGIN/COMMIT pairs per rotation
+(`revoke_session` then `create_session`), and DAV clients rotate
+constantly. New `rotate_session(old_id, new_session)` port method: revoke +
+insert + last-login stamp in one `with_transaction`. Gates: old session
+revoked, new session live, reuse-detection semantics untouched (family
+revocation still fires on replay). The per-rotation "Session … revoked"
+info-line is gone with the old method call (routine rotation is not a
+security event; explicit logout/family revocation still log).
+
+## [Q5] WOPI CheckFileInfo — three independent lookups overlapped
+
+The handler ran require(Read) → get_file → check(Update) serially; all
+three key off `(caller, file)` alone. Now `tokio::join!` with results
+evaluated in the original precedence (Read gate first, then 404, then the
+can_write hint — deny responses byte-identical; the Update probe still
+skips its query when the token has no write claim). Same fusion applied to
+`authorize_wopi_access` (host page / editor-url). Cold is the shape that
+matters: office editors poll CheckFileInfo through a session, but each
+(file × TTL-window) pays the cold chain once.
+
+## [Q6] Fused upload-quota gate
+
+`refuse_if_over_quota` (NC chunked PUT — runs on EVERY chunk) issued the
+user-envelope read and the drive-cap read serially. One `LEFT JOIN` row
+now carries both counter pairs; the verdict evaluators were extracted
+(`eval_user_envelope` / `eval_drive_cap`) and are shared by the old point
+methods and the fused one, so every error string is identical by
+construction. Gates: verdict identity across ok / drive-over / user-over
+(precedence) / unlimited / missing-drive. A `check_upload_quotas_by_folder`
+twin exists for folder-keyed callers; the three REST once-per-upload pair
+sites were left as-is (their two checks carry different rejection logs, and
+one query per whole upload isn't worth entangling that — see §Skipped).
+
+## [M1] `sized_json` — the 128-byte seed on every listing
+
+```
+cargo run --release --features bench --example bench_round12_micro    # §1
+```
+
+axum's `Json` serializes into `BytesMut::with_capacity(128)`; a 500-row
+listing (~190 KB) grows it through ~11 doubling reallocs, memcpy-ing ~1.3×
+the payload. `interfaces::api::sized_json` pre-sizes from the row count
+(FileDto ≈ 380 B serialized; estimate 384) and serves byte-identical output
+(gated). Applied to the four hot listing responses: `list_files` (which is
+UNBOUNDED — no page cap), folder resources, photos timeline, search (both
+verbs).
+
+## [M3] Security-header stack 5 → 1
+
+The CSP middleware already post-processed every response; the four static
+headers (`x-content-type-options`, `x-frame-options`, `referrer-policy`,
+`permissions-policy`) each rode their own `SetResponseHeaderLayer` on top.
+Folded into the same pass — inserted before the 304 early-return because
+the standalone layers stamped 304s too. Gate: status + full sorted header
+set byte-identical for json / html / 304 through real axum routers.
+
+## [M4] Media capture-metadata single-read (the ROUND11 deferred lead)
+
+```
+cargo run --release --features bench --example bench_round12_micro    # §4
+```
+
+`extract_blocking` read each image once wholesale for kamadak, then
+nom-exif re-opened the SAME file (`read_exif(path)`), and date-less images
+paid a third open (`read_track(path)` fallback). Videos opened twice (a
+doomed `read_exif` sniff, then `read_track`). Now: nom-exif parses from the
+kamadak buffer zero-copy (`MediaSource::from_memory` over the same `Bytes`
+allocation, API verified on the pinned 3.6.1), one reused `MediaParser`,
+and videos open once with a `kind()` dispatch. The track fallback for
+images SURVIVES (fed from the same bytes) — it covers MIME-mislabeled rows,
+the only case where it ever produced a date; behaviour is
+observable-identical (gated over dated/undated JPEG, PNG, crafted MP4 —
+corpus asserted non-vacuous: the crafted EXIF date and mvhd creation time
+must actually extract). Warm: 1.44x geomean. Cold cache (`drop_caches`
+arms): dated JPEG 0.81 → 0.34 ms, undated 0.97 → 0.30, PNG 0.12 → 0.06,
+MP4 0.050 → 0.032. Per-image opens 2-3 → 1; the backfill sweeps multiply
+this by the library size.
+
+## [M5] Chunked-upload session ops
+
+`prepare_chunk` ran `verify_session_owner` (own DashMap lookup + a
+`Uuid::to_string`) then re-fetched the same entry; `commit_chunk` did the
+same plus its `get_mut` (3 lookups + allocation per chunk). The owner gate
+now rides the operation's own lookup (same anti-enum not-found for unknown
+and foreign sessions — gated), and the uuid compares against a
+stack-encoded hyphenated form. 5 → 3 shard-lock round-trips and −2 allocs
+per chunk cycle.
+
+## [B1][B2] Blob-cache: moka byte-weigher index + the put_blob ordering fix
+
+```
+cargo run --release --features bench --example bench_blob_cache_index
+cargo run --release --features bench --example bench_blob_cache        # regression guard
+```
+
+The ROUND11 deferred headline. The cache index was a
+`tokio::sync::Mutex<LruCache>`: every cached chunk read took the one global
+async mutex to probe+promote (LRU `get` needs `&mut`), so a 100-chunk video
+playback was 100 serialized critical sections and concurrent readers
+contended process-wide — measured NEGATIVE scaling (2.08 → 1.07 Mops/s
+going from 1 to 2 readers). `moka::sync::Cache` with a byte weigher makes
+the probe lock-free (K=2 **2.17x**, K=8 1.46x; end-to-end warm reads with
+real files 1.00-1.15x on this 4-core box — the gap is the index share of
+the path and widens with cores/readers). moka also absorbs the byte budget:
+the manual `current_size` counter + `collect_evictions` sweep are gone; an
+eviction listener unlinks size-evicted `.blob` files. Safety gates: budget
+enforced (100 × 1 MiB into a 10 MiB cap → ≥88 files unlinked, survivors
+readable), a Replaced entry does NOT unlink its file, Explicit
+invalidations unlink at their call sites, and the per-hash single-flight
+still collapses 16 concurrent misses to 1 fetch. The `CachedRef` clone
+bundle (incl. a `cache_dir` PathBuf clone paid on every HIT for a miss-only
+struct) is gone — internals now borrow `self`.
+
+Two behavioural notes, both strict improvements: the write-through PUT
+paths now respect the byte budget (the old index deliberately skipped
+eviction there, letting write bursts overshoot until the next read-miss);
+and a restored over-budget cache trims at startup instead of on the next
+insert.
+
+**B2 (the ROUND11 correctness note):** `put_blob` populated the cache AFTER
+`inner.put_blob` — but every inner backend consumes the source file (local
+renames it, S3/Azure delete it post-upload), so the `fs::copy` failed 100%
+of the time, silently (`let _`), and the first read after a whole-file put
+(the backend-migration copier) re-downloaded the blob from the remote.
+Cache-first now, with invalidate+unlink if the inner put fails so a
+rejected blob can never be served. The round-3 stampede guard re-run passes
+against the migrated backend (16 → 1 remote fetches, cache file verified).
+
+## [F1] SPA list-view thumbnails (vitest gate)
+
+```
+cd frontend && npx vitest run src/lib/api/endpoints/round12.bench.test.ts
+```
+
+Both views requested the 400 px `preview` rendition; the list row draws it
+in a 40×40 slot (the 150 px `icon` rendition is already ≥2× retina density
+there). `thumbSizeForView` switches list rows to `icon` — ~7.1x fewer
+pixels per thumbnail, roughly 4-8 KB vs 20-40 KB encoded WebP each, across
+files/recent/favorites/trash/shared list views. Grid keeps `preview`
+(100×70 slot at 2x DPR genuinely needs it).
+
+## Rejected / reworked this round (the discipline working)
+
+- **Single-pass compression predicate**: the sweep flagged "~28 redundant
+  Content-Type header reads per compressible response" in `main.rs`'s
+  `And`-chain. The bench says otherwise: the monomorphized chain runs in
+  **4.6 ns / 0 allocs** total (straight-line inlined probes), and the
+  hand-fused single-pass node measured 5.2 ns on the compressible hot case
+  — within noise, sometimes slower. Not shipped; the declarative chain
+  stays. `bench_round12_micro` §2 keeps the reproducible evidence.
+
+## Considered and skipped (cost/benefit, not measurement)
+
+- **REST per-upload quota pair fusion** (multipart / native-chunked /
+  delta): the two checks sit in separate `if` blocks with distinct
+  rejection logs and folder-id guards; fusing saves ONE query per whole
+  upload (not per chunk) and would entangle that flow. The NC per-chunk
+  site — the hot one — is fused (Q6).
+- **NC per-session quota budget cache** (0 queries per chunk instead of 1):
+  needs a staleness/invalidation story vs concurrent sessions; the fused
+  read already halves the per-chunk cost with bit-identical semantics.
+  Flagged for a future round.
+- **`lto = "fat"` on the release profile**: the bench profile already uses
+  it; flipping release trades a large link-time regression for every
+  contributor and CI/Docker build against a low-single-digit runtime gain.
+  That's a project-level call for maintainers, not a bench-gated code
+  change — flagged, not shipped.
+
+## Deferred / flagged (not shipped this round)
+
+- **Grouped file/grid views are still unvirtualized** (files route
+  `groupBy != ''` mounts EVERY row in both view modes; ResourceList's
+  grouped GRID branch too — trash is grouped-by-default). Design prepared
+  this round: flatten groups into the existing `VirtualRows`
+  (photos-timeline pattern — headers as first-class rows, grid rows as
+  fixed-height strips of `gridColumns(width)` tiles), which also collapses
+  the per-section `VirtualList` scroll listeners the grouped LIST path
+  pays today (one `getBoundingClientRect` per section per scroll tick).
+  This is the next round's headline; it wants its own pass with UI gates.
+- **Duplicate `TraceLayer` on `/api`** (`routes.rs` layers it again under
+  the global `ClientIpMakeSpan` layer) and the **per-request `client_ip`
+  String** in the span factory — small, want their own measured arms.
+- **`CachedBlobBackend::local_blob_path` sync `stat`** (ROUND10/11 flag
+  stands — background-extraction paths only; needs an async port variant).
+- **Media hooks read the same blob up to 3×** per upload (thumbnail +
+  capture-metadata + faces each pull it independently; the latter two read
+  the RAW blob path directly, bypassing the content cache — and, on
+  encrypted deployments, reading ciphertext: correctness note for
+  maintainers, same class as the ROUND11 put_blob note).
+- **`mp3_duration::from_path` full-file frame scan** runs even when the
+  ID3 `TLEN` tag is present (ingest-path only). Preferring TLEN is a
+  speed/accuracy tradeoff on VBR files — maintainer call.
+- **Thumbnail orientation re-parses EXIF** that capture-metadata also
+  parses; reusing the persisted `orientation` is ordering-dependent
+  (hooks run concurrently) — needs a small sequencing decision.
+
+## Environment / methodology
+
+- `cargo run --release --features bench --example bench_round12_queries`
+  — needs Postgres; seeds and sweeps its own fixtures (BENCH_PASSES,
+  BENCH_SHR_USERS, BENCH_WOPI_FILES, BENCH_WARM_ITERS).
+- `cargo run --release --features bench --example bench_round12_micro`
+  — counting allocator; §4's cold arms drop the page cache (root; set
+  BENCH_COLD_ITERS=0 to skip).
+- `cargo run --release --features bench --example bench_blob_cache_index`
+  — index scaling + eviction/single-flight safety gates.
+- `cargo run --release --features bench --example bench_blob_cache`
+  — round-3 cross-round regression guard (passes against the moka index).
+- `cd frontend && npx vitest run src/lib/api/endpoints/round12.bench.test.ts`.

+GRID arm mounted **every** card, and the accumulated listing is the whole
+folder, so a big grouped grid mounted thousands of `.file-item`s (~8-10
+`<Icon>`s + ~8 buttons each), a multi-second main-thread block. `/trash` is
+grouped-by-default, so a grid-view trash page hit this on first load.
+
+The fix is the symmetric one the grouped-LIST arm already used and the
+flat-GRID arm already proved: **window each swimlane with its own
+`VirtualList`** (`windowClass="files-grid-view"` puts the card grid on the
+list's inner window). The outer grouped-grid container is a flex column
+(`.files-grouped-grid` / `.rl-grouped-grid`), NOT `.files-grid-view` — that
+class is itself a grid and would place each header/VirtualList into a cell;
+the grid now lives per-section. The files route additionally folds each
+group's separate `folders`/`files` into one ordered `Entry` stream
+(`groupedEntries`, folders-then-files — the exact old render order) so a
+section feeds one `VirtualList`. The prior claim in a code comment that
+"`files-grid-view` … can't host the windowing spacer" was simply wrong (the
+flat grid disproves it).
+
+Gate: render the real `ResourceList` in grouped GRID mode at N=800 in one
+bucket — mounted `.file-item` count is **<120** (viewport+overscan bounded,
+`<N/4`), a swimlane header confirms the grouped path, and the `.vlist`
+spacer still reserves the full scroll height (cards windowed, not dropped).
+Preserved (unchanged, verified by the existing files/trash/recent tests):
+selection (`SvelteSet.has` reads stay inside the row), the ROUND11 §S2
+fine-grained favorite star (the grouping derive reads only item identity +
+order, never `favoriteIds`/`selected`), drag-drop, keyboard, and the
+ROUND12 §F1 `thumbSizeForView` icon/preview switch.
+
+Scope note: this windows the grouped arms (the actual defect) while leaving
+the already-windowed flat arms on `VirtualList`. Unifying all four arms onto
+one `VirtualRows` (the photos-timeline single-pass model) is a clean
+follow-up that also removes the per-section scroll listeners — deferred so a
+pitch-measurement change can't regress the flat views that are fine today.
+
+## [Q1] Group-notification recipient expansion
+
+```
+cargo run --release --features bench --example bench_round13_queries   # §1
+```
+
+`RecipientNotificationService` fans a group share out to its members via
+`get_users_by_ids`, whose 21-column projection dragged the ≤512 KiB avatar
+`image` (TOAST-detoasted per row) and the `ui_preferences` JSONB — of which
+the notification path reads *neither* (only email/eligibility fields). It is
+the ROUND12 §Q1 sharee-avatar pattern on the group-notify path, ×M members.
+`get_users_by_ids` has exactly one production caller, so it is narrowed
+in-place (image + ui_preferences dropped; doc updated: notification-recipient
+projection). 30-member fan-out: 8.60 → 0.25 ms, ~7.7 MB of avatar/JSONB kept
+off the wire. Gate: identical `(id, email, notify_on_share)` set.
+
+## [Q2] Login provisioning EXISTS probes
+
+The Personal-Drive / Default-Calendar / Default-Address-Book provisioning
+hooks fire on EVERY login; the calendar and address-book hooks tested
+"already provisioned?" by `list_*_by_owner(..).is_empty()` — hydrating every
+owned row (calendars carry description/color TEXT) just to look at
+emptiness. New `has_owned_calendar` / `has_owned_address_book` back it with
+`SELECT EXISTS(...)` (the ROUND9 §7 `Drive::is_empty` COUNT→EXISTS pattern),
+short-circuiting at the first row. 4 owned calendars: 0.193 → 0.170 ms; the
+margin widens with the owned-row count. Gate: EXISTS agrees with
+hydrate-all, present and absent. (The drive hook's unconditional `set_role`
+re-emit on every login — an authz write — is flagged, not shipped: it's a
+deliberate self-heal and touches authz semantics, the ROUND12 class that
+awaits maintainer sign-off.)
+
+## [Q3] Recent-access prune only on insert
+
+`RecentService::record_access` ran `upsert_access` then `prune`
+unconditionally — but a re-access is an `ON CONFLICT DO UPDATE` that only
+refreshes a timestamp and can never push the user over the cap, so the prune
+(a DELETE over an `OFFSET` self-subquery) was a wasted round-trip on that
+common path. `upsert_access` now `RETURNING (xmax = 0)` reports whether it
+inserted; the service prunes only then. A single fused CTE was rejected: a
+data-modifying CTE's outer DELETE sees the pre-insert snapshot, so it would
+under-prune by one on the boundary insert — the two-statement,
+prune-on-insert shape is the correct one. Re-access: 0.567 → 0.324 ms. Gate:
+`xmax` flags insert vs update correctly and the row count stays at the cap.
+
+## [L1] Locale supported-codes precompute
+
+```
+cargo run --release --features bench --example bench_round13_micro   # §L1
+```
+
+The `Accept-Language` extractor rebuilt the supported-locale list — N fresh
+heap `String`s + two `Vec`s — on every anonymous request, though the set is
+fixed at startup (the ROUND10 §15 "process-invariant rebuilt per request"
+class). `LocaleRegistry` now materializes `supported_codes: Arc<Vec<String>>`
+once in `discover()`; the extractor borrows it and builds only the `&[&str]`
+view the crate needs. 16 locales: 616 → 17.3 ns, 18 → 1 allocs per anonymous
+request. Gate: precomputed and rebuilt code SETS identical (order is
+irrelevant — `accept_language::intersection` ranks by header q-values).
+
+## [H1][H2] HTTP micro-pack
+
+```
+cargo run --release --features bench --example bench_round13_micro   # §H1, §H2
+```
+
+- **Duplicate `TraceLayer` on `/api`** — `routes.rs` layered its own
+  `TraceLayer::new_for_http()`, but the global `TraceLayer +
+  ClientIpMakeSpan` stack in `main.rs` wraps the whole app (the `/api`
+  router is nested into it), so every `/api` request paid TWO span +
+  response-future layers. Removed; end-to-end 1.86 → 1.42 µs/request, −6
+  allocs. Gate: response status identical with 1 vs 2 layers.
+- **`client_ip` span field** — `ClientIpMakeSpan::make_span` allocated an
+  owned `String` per request purely to feed `%client_ip` (Display). New
+  borrow-only `ClientIpDisplay` renders straight into the span's field
+  storage (forwarded header borrowed, peer rendered in place): 187 → 173 ns,
+  −1 alloc. Gate: byte-identical to the owned resolver across all four
+  resolution cases.
+
+## Not shipped — correctness finding surfaced by the perf sweep
+
+- **Media hooks' raw blob reads are broken, not merely duplicated.** The
+  round-12 deferred "media metadata + faces + thumbnail each read the blob"
+  lead was investigated for a shared-read refactor. The investigation found
+  the premise was wrong: `MediaMetadataService` and `FaceIndexingService`
+  read `.blobs/{file_hash}.blob` **directly**, but that path exists only for
+  **local + unencrypted + single-chunk** blobs — for a normal multi-MB
+  (multi-chunk) photo it does not exist, on S3/Azure there is no local
+  `.blobs` tree, and on encrypted backends it is ciphertext. So today those
+  two hooks silently produce **no capture date / no GPS / no faces** for the
+  common case, while only the thumbnail hook (which goes through
+  `dedup.read_blob_bytes`, honoring chunk-reassembly + decryption) works.
+  The fix is to route both through `read_blob_bytes` — but that is a
+  **correctness fix that is perf-neutral-to-negative** (it makes reads that
+  currently fail actually run), so it does not belong in a benchmark-gated
+  perf round. Flagged for maintainers as a correctness bug with the exact
+  call sites; a shared-`Bytes` provider (single decode-plaintext read fanned
+  to the hooks) is the perf follow-up once the correctness fix lands.
+
+## Deferred / flagged (not shipped this round)
+
+- **Unify all four listing arms onto one `VirtualRows`** (flat + grouped ×
+  list + grid), the photos-timeline single-pass model — removes the
+  per-section scroll listeners the grouped paths now carry and the
+  four-branch render in both files route and ResourceList. Wants a
+  pitch-measurement pass so it can't drift the flat views that work today
+  (V1 scope note).
+- **Drive-provisioning `set_role` re-emit on every login** (authz write; a
+  self-heal for a historical partial-provision case) — needs maintainer
+  sign-off, same class as the ROUND12 auth-write deferrals.
+- **NC per-session quota budget cache** (0 queries/chunk instead of the
+  ROUND12 fused 1) — needs a staleness/invalidation story (ROUND12 flag
+  stands).
+- **`mp3_duration` full-file scan when the ID3 `TLEN` tag is present**
+  (ingest path) — preferring TLEN is a speed/accuracy tradeoff on VBR files;
+  maintainer call.
+- **Thumbnail orientation re-parses EXIF** that capture-metadata already
+  parsed — reusing the persisted `orientation` is ordering-dependent (hooks
+  run concurrently).
+- **`CachedBlobBackend::local_blob_path` sync `stat`** (ROUND10-12 flag
+  stands; needs an async port variant).
+- **`admin_settings_service` ~7 sequential autocommit upserts on OIDC save**
+  — admin-only, fired a handful of times per deployment; confirmed still
+  present, judged not worth entangling the hot-reload logic (same verdict as
+  ROUND12's skipped REST quota-pair fusion).
+
+## Environment / methodology
+
+- `cargo run --release --features bench --example bench_round13_queries`
+  — needs Postgres; seeds + sweeps its own fixtures (`BENCH_PASSES`,
+  `BENCH_GROUP`, `BENCH_CALS`, `BENCH_RECENT_CAP`).
+- `cargo run --release --features bench --example bench_round13_micro`
+  — counting allocator; §L1 reads the shipped `frontend/static/locales`.
+- `cd frontend && npx vitest run src/lib/components/round13.bench.test.ts`.

+# Round 14 — narrow projections, per-request auth allocations, CalDAV read-emitter buffers, frontend set churn
+
+Benchmark-gated, same rule as ROUND2–13: every change ships with a
+BEFORE/AFTER benchmark and an equivalence/safety gate; an AFTER that doesn't
+beat its BEFORE is rolled back (never applied). The roll-back rule is encoded
+directly into each harness as a `GATE FAIL … rollback` non-zero exit (Rust) or
+a threshold `expect()` (frontend), so a regression fails CI rather than
+shipping.
+
+This round is a broad micro-sweep: one over-fetch on the People lightbox path,
+five per-request allocations on the authenticated `/api` + DAV hot path, the
+CalDAV read-emitters (which never got the allocation treatment their CardDAV
+twin already ships), and two frontend per-page set-churn fixes.
+
+Measured on 4 cores / 15 GiB, local PostgreSQL 16 (release profile for the Rust
+examples; Node 22 / vitest 4 for the frontend). Reproduce any row with the
+command in its section.
+
+## Summary
+
+| # | change | key metric | before → after |
+|--:|---|---|---|
+| Q1 | Lightbox face boxes — narrow `SELECT id, person_id, bbox` with the caller filter in SQL, vs hydrating the full 10-column row (incl. the 2 KiB `embedding` BYTEA, decoded per face) and filtering in Rust | 15-face group photo | **0.312 → 0.219 ms (1.43×)** · 32 040 → 840 B/req (38× less wire, scales with face count) |
+| A1 | Cookie auth reads the access token with the borrow-only `extract_cookie_str` (already backs CSRF) instead of `extract_cookie_value`'s owned `String` | per cookie-authed `/api` req | 157.7 → 146.5 ns · **1 → 0 allocs** |
+| A2 | `compute_relevance` ASCII case-fold fast path vs `name.to_lowercase()` per result row (Unicode fallback preserved) | 12-row result page | **661.9 → 473.6 ns (1.40×)** · 12 → 3 allocs |
+| A3 | `sub` pre-parsed to `Uuid` at decode time vs re-parsing the 36-char claim on every request (even cache hits) | per authed req | **22.7 → 0.7 ns (32.9×)** CPU |
+| A4 | Auth middleware borrows `request.headers()` instead of taking axum's `HeaderMap` extractor (a full map clone) — JWT **and** NextCloud paths | per authed `/api`+DAV+NC req | **239.1 → 7.6 ns (31.5×)** · **2 → 0 allocs** |
+| A5 | CalDAV `getlastmodified` via the stack `rfc2822_utc` (byte-identical to chrono) vs `updated_at.to_rfc2822()` heap `String` per event | 5 events | 178.2 → 148.7 ns · **5 → 0 allocs** |
+| A6 | CalDAV per-event `href` + quoted `etag` written into reused page buffers vs a fresh `format!` `String` pair per event | 40-event page | **8 399 → 2 417 ns (3.48×)** · **240 → 6 allocs** |
+| F1 | `t()` shares one frozen `EMPTY_PARAMS` for the no-interpolation call forms vs a throwaway `{}` per call | 4M no-param calls | 34.1 → 28.8 ms (1.18×) · −1 alloc/call |
+| F2 | Favorites `favoriteIds` is a persistent set with per-page `add` vs a brand-new `SvelteSet` over the whole accumulated list each infinite-scroll page | 40-page drain | **35.5 → 1.6 ms (22.3×)** · O(N²) → O(N) |
+
+## [Q1] Lightbox face boxes — narrow projection + SQL-side caller filter
+
+```
+cargo run --release --features bench --example bench_round14_queries   # §Q1
+```
+
+`GET /api/people/faces/{file_id}` fires on every lightbox open of a
+face-tagged photo. `people_service::faces_for_file` (the sole caller of the
+repo method) builds `FaceBoxDto { id, person_id, x,y,w,h }` — it reads **only**
+`id`, `person_id`, `bbox`. But the repo's `faces_for_file` selected all ten
+columns, dragging the 2 048-byte `embedding` BYTEA (`512 × f32`) across the
+wire **and decoding it into a `Vec<f32>` per face** (`row_to_face`), plus five
+more unused columns, then filtered `user_id == caller` in Rust. For a group
+photo that is ~2.1 KB/face fetched where ~40 B is needed.
+
+The fix mirrors the already-accepted `person_face_stats` narrowing (the port
+doc there already cites "the 2 KiB embedding BYTEA per row"): a new
+`face_boxes_for_file(file_id, user_id)` port method selects only
+`id, person_id, bbox` and pushes the caller scope into `WHERE user_id = $2`
+(driven by `idx_faces_file`), returning a lightweight `FaceBox`. 15-face group
+photo: 0.312 → 0.219 ms, 32 040 → 840 B/req; the margin widens with face count
+and is larger over a networked PG. Gate: the `{(id, person_id, bbox)}` set is
+byte-identical before/after (all 15 faces), and the caller scope is preserved
+(now enforced in SQL rather than a Rust `.filter`).
+
+## [A1]–[A6] Auth + CalDAV micro-pack
+
+```
+cargo run --release --features bench --example bench_round14_micro   # §A1–§A6
+```
+
+Counting-allocator micro-bench; each section is BEFORE (the shipped shape, or
+the shipped function itself) vs AFTER, with a byte-identity/equivalence gate.
+
+- **[A1] Cookie token extract.** `auth_middleware`'s cookie arm called
+  `extract_cookie_value` → an owned `String` whose only use is to be reborrowed
+  as `&str` into `validate_token`. The borrow-only twin `extract_cookie_str`
+  already exists (it backs the CSRF middleware, ROUND11 §6). Swapped: −1 alloc
+  on every SPA/browser `/api` request. Gate: byte-identical value.
+- **[A2] `compute_relevance` ASCII fast path.** The query side was already
+  hoisted, but the *name* side still did `name.to_lowercase()` (full Unicode)
+  per result row — and per keystroke on the suggest path. For the
+  overwhelmingly common all-ASCII filename that is pure waste. New path:
+  `eq_ignore_ascii_case` + an allocation-free ASCII case-insensitive
+  `starts_with`/`contains`; non-ASCII names fall back to the exact
+  Unicode-lowercase comparison. 12-row page: 1.40×, 12 → 3 allocs. Gate: the
+  ASCII path equals the Unicode path across a mixed ASCII/`é`/`ß`/`ï` corpus
+  (exact/prefix/substring/miss).
+- **[A3] `sub` → `Uuid` pre-parse.** `TokenClaims.sub` is a `String`; the
+  middleware re-ran `Uuid::parse_str` on the 36-char subject on *every* request,
+  downstream of the validation cache (which returns the same
+  `Arc<TokenClaims>`), so the parse repeated on ~all-hit steady state. A new
+  `sub_id: Uuid` is parsed once in `From<JwtClaims>` (amortized over the cache
+  TTL); the middleware reads a `Copy`. 22.7 → 0.7 ns. A verified token we signed
+  always carries a UUID sub; the nil sentinel is rejected defensively, exactly
+  like the old parse-error branch. Gate: pre-parsed `sub_id` equals a fresh
+  parse.
+- **[A4] Drop the `HeaderMap` clone.** Both `auth_middleware` (JWT/Basic/cookie
+  — all `/api`, WebDAV, CalDAV, CardDAV) and the NextCloud
+  `basic_auth_middleware` took axum's `HeaderMap` extractor, i.e. a full
+  `parts.headers.clone()` (~2 allocs) per request, purely to *read* the
+  Authorization/Cookie headers. Removed; the middleware borrows
+  `request.headers()` directly. This is a borrow restructuring, not a logic
+  change: the header borrow is dead (NLL) by the time each arm reaches
+  `request.extensions_mut()` / `next.run(request)`, so no owned copy is needed
+  and the auth decisions are byte-identical. 239.1 → 7.6 ns, 2 → 0 allocs — the
+  single highest-reach allocation removed this round. Gate: the token extracted
+  from a cloned map equals the token from the borrowed map.
+- **[A5] CalDAV `getlastmodified` stack render.** The CalDAV read-emitters
+  (`write_report_page` → event props, `write_collection_event_page`, and the
+  two per-calendar prop writers) formatted `updated_at.to_rfc2822()` into a
+  fresh heap `String` per event — up to `CALDAV_STREAM_PAGE_EVENTS = 500` per
+  page, on the REPORT (`calendar-query`/`multiget`/`sync-collection`) and
+  collection-PROPFIND paths every client polls constantly. The CardDAV twin
+  already replaced exactly this with the `[u8; 31]` stack renderer
+  `common::fmt::rfc2822_utc` (ROUND10 §13), parity-tested byte-for-byte against
+  chrono across 60 years, with the chrono fallback for out-of-4-digit-year
+  timestamps. Ported via a shared `write_lastmodified_text` helper at all five
+  sites: 5 → 0 allocs. Gate: stack render byte-identical to `to_rfc2822`.
+- **[A6] CalDAV per-event `href` + `etag` reused buffers.** Same emitters
+  allocated a fresh `format!("{}{}.ics", …)` href and a `format!("\"{}\"", id)`
+  quoted etag `String` **per event**. The CardDAV emitter already reuses a
+  single page buffer (`clear()` + `write!`). Ported: `write_report_page` /
+  `write_collection_event_page` hold reusable `href` + `etag` buffers threaded
+  through `write_event_response` into the prop writers (its only caller), so a
+  40-event page allocates that storage once, not 80 times. 3.48×, 240 → 6
+  allocs/page. Gate: reused-buffer bytes identical to the per-event `format!`.
+
+## [F1][F2] Frontend set/alloc micro-pack
+
+```
+cd frontend && npx vitest run src/lib/components/round14.bench.test.ts
+```
+
+- **[F1] `t()` shared empty params.** The ubiquitous `t('k', 'Fallback')` and
+  bare `t('k')` (default `= {}`) allocated a throwaway params object on every
+  call, though for a cache-hit string with no `{{…}}` `interpolate` returns
+  before reading params. `t()` runs ~10×/row. Hoisted one frozen
+  `EMPTY_PARAMS`; 4M no-param calls 34.1 → 28.8 ms (the alloc reduction shows
+  as ~1.18× even on V8's cheap young-gen `{}`). Gate: identical output for the
+  bare / string-fallback / params forms; perf gate requires the shared arm be
+  no slower.
+- **[F2] Favorites `favoriteIds` incremental set.** The favorites route derived
+  `favoriteIds = new SvelteSet(items.map(i => i.id))`. Every infinite-scroll
+  page (`raw = [...raw, ...page]`) rebuilt a **brand-new** set over the whole
+  accumulated list — O(N) per page, O(N²) across a drain — and, being a new
+  instance each page, invalidated every mounted star reader. Since every item
+  on this page is a favorite and removed items aren't rendered, the set only
+  has to be a *superset* of the displayed ids, so the fix keeps one persistent
+  `SvelteSet` and `add`s only the fresh page's ids (`clear` on reset, `delete`
+  on unfavorite) — the shape `recent` already ships (`replaceSet`, ROUND6). A
+  40-page × 50 drain: 35.5 → 1.6 ms (22.3×). Gate: final membership identical
+  to the rebuild-per-page model.
+
+## Not shipped — investigated, deferred, or flagged
+
+Every item below was surfaced and verified this round but deliberately left
+out of the benchmark-gated set — either it needs a decision the perf pass
+can't make, or it isn't cleanly wall-benchable, or it's a correctness bug that
+must not ride a perf banner.
+
+### Query-shape (needs Postgres; verified, deferred)
+- **`music_storage_adapter::list_public_playlists` 1 + N `COUNT(*)`** — one
+  `SELECT COUNT(*) FROM audio.playlist_items` per playlist (up to 101
+  round-trips at `limit=100`). Foldable into one `LEFT JOIN … GROUP BY`. It's
+  the public-gallery path (`include_public` defaults false), so opt-in; queued
+  with its bench. Its two dead siblings `list_playlists_by_owner` /
+  `list_shared_with_user` carry the same N+1 with **no live caller** (replaced
+  by `get_playlists_by_ids` post-ROUND3) — flag for deletion, not optimization.
+- **Contact REST listings over-fetch the `vcard` TEXT** — `search_contacts`,
+  `get_contacts_by_address_book_paginated`, and `get_contacts_in_group` select
+  the full serialized card (the largest column; multi-KB with an embedded
+  `PHOTO;ENCODING=b`), but every caller maps to `ContactDto`, which has **no**
+  `vcard` field. Wants a *lite* row mapper (the non-paginated sibling is shared
+  with the CardDAV stream, which genuinely needs `vcard`), so it's a contained
+  refactor rather than a blanket SELECT change.
+
+### CPU/alloc (verified, deferred or below the noise floor)
+- **`content_index_worker`**: (a) clones the full extracted text into the
+  per-batch `text_by_hash` map even for unique blobs (dead clone in the
+  common one-file-per-blob case; hold `Arc<str>` or gate on multiplicity);
+  (b) calls `text_extractor::supports()` (which lowercases MIME + extension,
+  1–2 allocs) **twice per file** per drain batch. Both are reseed-throughput,
+  not request-latency — worth one worker micro-bench of their own.
+- **`tantivy_content_index::search_blocking` builds a `SnippetGenerator` even
+  when there are zero hits** — trivial `if top_docs.is_empty() { return … }`.
+- **`exif_service` double-allocates** on Make/Model/GPS-ref
+  (`display_value().to_string().trim_matches('"').trim().to_string()` — the
+  intermediate `to_string` is thrown away). Per-image, background.
+- **REST calendar-event edit** re-`format!`s the whole `ical_data` body once
+  per changed property (`update_ical_property` / `remove_ical_property`), so a
+  6-field PATCH reallocates the body ~7×. Per-edit (rare vs CalDAV reads);
+  wants one working buffer.
+
+### Storage I/O (cached-remote deployment class; verified, deferred)
+- **`CachedBlobBackend` re-runs `fs::create_dir_all(prefix)` per cache write**
+  — unlike `LocalBlobBackend::initialize`, which pre-creates all 256 prefix
+  dirs; a cached-remote upload pays a redundant `mkdir(EEXIST)+stat` + blocking
+  dispatch per chunk. Pre-create at init and drop the hot-path call.
+- **`CachedBlobBackend` eviction listener `std::fs::remove_file` on the reactor
+  thread** — moka delivers the listener on the calling (tokio worker) thread,
+  so at steady state each write-through insert unlinks a victim inline (p99
+  stall). Hand the unlink to `spawn_blocking` / a drain task.
+- **`dedup_service` hash-`String` re-allocations** — `distinct_hashes` rebuilds
+  a set the streaming loop already had (`session_seen`); `settle_batch` clones
+  every batch hash to bind the pin query. Alloc-count only (within noise on a
+  throughput bench); report as such.
+- **`encrypted_blob_backend` emits 64 KiB plaintext frames** where every other
+  backend streams 256 KiB (the comment claiming parity is wrong) → 4× frames on
+  decrypted reads; AES dominates, so likely within noise — verify before
+  shipping.
+
+### Frontend (bigger refactors — their own pass)
+- **`ResourceList.sections` re-buckets the whole accumulated list per page**
+  (O(N²) across a grouped-view drain; trash is grouped-by-default and its
+  `bucketOf` does `Date` math per item). The fix is the proven `PhotoTimeline`
+  incremental-builder pattern (persistent `Map` + append-detection); it's the
+  flagship follow-up, same class as the ROUND13-deferred "unify all four
+  listing arms onto one `VirtualRows`".
+- **`shared/+page.svelte` rebuilds the full `lanes` tree** per page **and** on
+  every single grant edit (`raw = [...raw]` to force reactivity); and the
+  favorites/recent/trash routes re-project `items`/`contextMap` per page.
+  Co-solved by the same incremental builder.
+
+### Already done / correctness (not perf)
+- **JWT-claims `Arc<str>`** — the ROUND6/ROUND9-deferred "cheapest known win on
+  the /api path" was **already shipped in ROUND10** (`TokenClaims.username`/
+  `email: Arc<str>`, `CurrentUser` build = 1 alloc). The residual `Arc::new`
+  is structurally required (shared with `NcSession`). Do not re-open.
+- **Media hooks' raw blob reads are broken, not merely duplicated** (ROUND13
+  finding stands): `MediaMetadataService` / `FaceIndexingService` read

+# Round 15 — grouped-listing O(N²) rebucket, exif/reseed allocations, tantivy zero-hit snippet skip
+
+Benchmark-gated, same rule as ROUND2–14: every change ships with a
+BEFORE/AFTER benchmark and an equivalence/safety gate; an AFTER that doesn't
+beat its BEFORE is rolled back (never applied). The roll-back rule is encoded
+directly into each harness as a `GATE FAIL … rollback` non-zero exit (Rust) or
+a threshold `expect()` (frontend), so a regression fails CI rather than
+shipping.
+
+This round lands the ROUND14-deferred **flagship** — the grouped-listing
+`sections` rebuild that was the last O(N²)-per-page accumulation left in the
+SvelteKit listing surfaces — plus three backend items pulled from the same
+deferred list: two allocation cuts on the photo-ingest / content-reseed worker
+paths, and a wasted `SnippetGenerator` build removed from the zero-hit content
+search path.
+
+Measured on 4 cores / 15 GiB, local PostgreSQL not needed for any Round-15 arm
+(all no-Postgres: release profile for the Rust examples; Node 22 / vitest for
+the frontend). Reproduce any row with the command in its section.

+
+## [F1] Grouped listings — incremental swimlane builder
+
+```
+cd frontend && npx vitest run src/lib/utils/resourceSections.bench.test.ts
+```
+
+Every grouped listing page (`/trash`, `/recent`, `/favorites`,
+`/shared-with-me`) loads its rows via infinite scroll (`raw = [...raw,
+...page]`), and `ResourceList`'s `sections` `$derived.by` re-bucketed the
+**whole accumulated list** on every page: Σ ≈ O(N²/page) `bucketOf` + `ctxOf`
+calls across a drain, and a brand-new rows array for *every* bucket each page
+(so `VirtualList` re-diffed every swimlane every page). This was the ROUND14
+"flagship follow-up" — the same O(N²)-per-page class ROUND6 fixed for the files
+listing, ROUND14 §F2 for favorites' `favoriteIds`, and `PhotoTimeline` for the
+photos grid.
+
+`ResourceSectionsBuilder` (extracted to `$lib/utils/resourceSections`, off the
+Svelte reactive graph so it's unit/benchmark-testable) exploits the append
+invariant: a grouped listing is server-sorted by the active group's `orderBy`,
+so a fresh page only ever extends existing buckets or appends new ones. It
+detects the append (prefix-identity on the boundary object), re-buckets only
+the fresh page, and hands back the **same array reference** for every untouched
+bucket — the property `VirtualList` (which diffs its `items` prop by reference)
+relies on to skip re-rendering it — while emitting a fresh array only for
+buckets the page actually grew. Any non-append (group-by switch, deletion,
+dotfile-filter toggle) falls back to a full rebuild, so the output is always
+deep-equal to the pure `buildResourceSections` reference.
+
+Correctness does **not** depend on bucket contiguity: the one non-monotonic
+group-by in the set — trash grouped **by drive** but ordered by name, so a page
+sprays items across every already-emitted drive bucket — stays byte-for-byte
+equal to the full rebuild (it just refreshes more buckets per page). Header
+labels are recomputed every sync (never cached): a group-by's `labelOf` can
+resolve asynchronously (owner / sharer names arrive after the rows), and a
+cached label would freeze the header at its fallback.
+
+50×50 (2 500-item) month-bucketed drain: **63 750 → 2 500 `bucketOf` calls
+(25.5× fewer), 12.5 → 1.3 ms wall (9.9×)**. Gates: (1) equivalence — the
+incremental output is deep-equal to `buildResourceSections` at *every* page for
+both a contiguous (date) and a non-contiguous (drive) group-by; (2) reference
+stability — untouched buckets keep their exact array reference across an append
+while a grown bucket gets a fresh one; (3) correct fallback on group-by switch,
+deletion and the flat pass-through; (4) perf — `bucketOf` work is exactly O(N)
+across the drain and wall drops ≥3×.
+
+## [B1]–[B2] exif / content-reseed allocation cuts
+
+```
+cargo run --release --features bench --example bench_round15_micro
+```
+
+Counting-allocator micro-bench; each section is BEFORE (the shipped-before
+shape) vs AFTER (the shipped function / shape) with a byte-identity gate.
+
+- **[B1] exif `Make`/`Model` single-allocation trim.** `ExifService::extract`
+  read the camera make + model as
+  `field.display_value().to_string().trim_matches('"').trim().to_string()` —
+  the first `to_string()` materializes the display value (unavoidable), then
+  `.trim_matches('"').trim().to_string()` allocates a **second** `String` for
+  the trimmed copy and drops the first. The new `display_value_trimmed` applies
+  the same two-stage trim in place on the already-owned buffer (`drain` drops
+  the stripped prefix, `truncate` the suffix — both reuse the allocation), so a
+  quoted `"Canon"` costs one allocation instead of two. Per ingested photo (the
+  Make + Model fields). 4 sample values/op: **8 → 4 allocs/op (2 → 1 per
+  field), 1.26× wall**. Gate: byte-identical to the old chain across quoted /
+  padded / clean shapes.
+- **[B2] Content-index worker single `supports()` classify.** `supports`
+  lowercases the MIME (and, on a generic MIME, the extension) — 1–2 allocations
+  — and the drain loop called it **twice per file**: once in the
+  `wanted_hashes` filter, once again in the per-file records loop. The worker
+  now classifies each file once into a `Vec<bool>` and threads the flag through
+  both. On a full reseed that is one redundant classify (and its allocations)
+  removed for *every file in the library*. 256-file batch: **704 → 353
+  allocs/op, 34.5 → 16.7 µs (2.07×)**. Gate: the `(wanted, supported)` tallies
+  are identical before/after.
+
+## [B3] Tantivy zero-hit snippet skip
+
+```
+cargo run --release --features bench --example bench_round15_tantivy
+```
+
+`TantivyContentIndex::search_blocking` built the `SnippetGenerator` from the
+query right after the `TopDocs` search — but `SnippetGenerator::create`
+compiles the query against the index (collects query terms, looks up each
+term's document frequency, builds the weighting), and when the query matched
+**no** documents that generator is never used: the per-hit loop is empty. A
+content search for a term that isn't in any indexed document (a common miss)
+paid that build for nothing on the request path.
+
+The fix returns `Ok(Vec::new())` the moment `top_docs.is_empty()`, before the
+create. The bench reproduces the exact skipped operation on a RAM index built
+with the public tantivy API (same crate + version): BEFORE = search + create,
+AFTER = search + the `is_empty()` early return; the delta is the wasted create.
+No-hit query against a 400-document index: **1 575.6 → 1 237.2 ns (1.27×), 21 →
+19 allocs/op** — the create adds ~338 ns + 2 allocs on top of the search on
+*every* zero-hit content query, and its per-term `doc_freq` lookups grow with
+the index (the RAM bench's 400 docs understate the production term dictionary).
+Gates: the miss query genuinely returns zero hits, and a control arm confirms a
+term that *does* hit still yields a snippet fragment (the skip only ever
+triggers on a true zero-hit query).
+
+## Not shipped — carried forward from the ROUND14 deferred list
+
+Still queued, unchanged in scope (each wants its own decision, Postgres
+fixture, or bigger refactor):
+
+- **Query-shape (needs Postgres):** `music_storage_adapter::list_public_playlists`
+  1 + N `COUNT(*)` fold (opt-in public-gallery path); contact REST listings
+  (`search_contacts`, `get_contacts_by_address_book_paginated`,
+  `get_contacts_in_group`) over-fetch the multi-KB `vcard` TEXT though every
+  caller maps to a `ContactDto` with no `vcard` field (wants a *lite* row
+  mapper, since the non-paginated sibling is shared with the CardDAV stream).
+- **Frontend:** `shared/+page.svelte` rebuilds the full `lanes` tree per page
+  and on every grant edit; the same incremental-builder pattern F1 uses is the
+  follow-up. (F1 removed the `ResourceList.sections` half of the ROUND14
+  "flagship" bullet; the `lanes` half remains.)
+- **CPU/alloc (background):** REST calendar-event edit re-`format!`s the whole
+  `ical_data` body once per changed property; `dedup_service` hash-`String`
+  re-allocations; `exif_service` still double-allocates the GPS-ref display in
+  `parse_gps_coord` (single-alloc, low-frequency — folded into B1's helper is
+  possible but the ref is compared to `"S"`/`"W"` as a borrow, so it never
+  needed the second alloc the Make/Model path did).
+- **Storage I/O (cached-remote class):** `CachedBlobBackend` per-write
+  `create_dir_all` + inline eviction `remove_file` on the reactor thread;
+  `encrypted_blob_backend` 64 KiB vs 256 KiB plaintext frames.
+

+| M1 | folder display constants — the trash-listing / NC-search-REPORT / path-resolver folder branch built `Arc::<str>::from("fas fa-folder")` (+ 2 more): 3 heap allocs/row where the sibling file branch already used the interned `Arc` clone | 3 fields/folder row | **3.00 → 0.00 allocs/op**, 1.14× wall |

+| M3 | `nc_href` — every NC PROPFIND/REPORT href allocated a per-segment `Vec<Cow>`, a joined String and the `format!`; one pre-sized buffer keeps `urlencoding::encode` (identical bytes) | 5 hrefs/op | **38.00 → 27.00 allocs/op**, 1.44× wall |
+| M4 | NC preview `fileId` — the handler `collect()`ed the digit prefix into a String only to reparse it to `i64`; parse the borrowed prefix slice instead | 5 ids/op | **4.00 → 0.00 allocs/op**, 2.51× wall |
+
+## [F1] "My shares" — incremental lanes builder
+
+```
+cd frontend && npx vitest run src/lib/utils/sharedLanes.bench.test.ts
+```
+
+The shares page pages its outgoing grants in via infinite scroll
+(`raw = [...raw, ...page.items]`), and the `lanes` `$derived.by` re-bucketed the
+whole accumulated (kind-filtered) list on every page — allocating a fresh lane
+object and a fresh `rows` array for *every* lane each time — Σ ≈ O(N²/page)
+`emit` calls across a drain. It also re-fired on every grant edit (role/expiry/
+password), each of which reassigns `raw`, re-bucketing the entire list for a
+one-row change.
+
+`SharedLanesBuilder` (extracted to `$lib/utils/sharedLanes`, off the Svelte
+reactive graph so it's unit/benchmark-testable) is the F1-flagship pattern
+generalized for the lanes shape, which differs from `ResourceList`'s sections
+in two ways: **fan-out** (one grant item contributes rows to *many* lanes in the
+"shared with" group-by) and a **header captured at first appearance** (vs a
+label recomputed each sync). On an append it re-emits only the fresh page and
+hands back the same `rows` array reference for every untouched lane, emitting a
+fresh array only for lanes the page actually grew. Any non-append (group-by
+switch, grant edit, kind-filter toggle) falls back to a full rebuild, so the
+output is always deep-equal to the pure `buildLanes` reference — including the
+non-contiguous "shared with" group-by, where a page sprays rows across
+already-emitted subject lanes (the same non-monotonic case F1 handled for trash
+grouped by drive). The O(1) append test is shared with `resourceSections` via
+`isAppendExtension` (extracted this round, re-validated by F1's own gate).
+
+50×50 (2 500-item) drain: **63 750 → 2 500 `emit` calls (25.5× fewer), 8.8×
+wall**. Gates: (1) equivalence — deep-equal to `buildLanes` at *every* page for
+both the by-files (contiguous) and by-subject (non-contiguous fan-out)
+group-bys; (2) reference stability — untouched lanes keep their exact array
+reference across an append while a grown lane gets a fresh one; (3) correct
+fallback on group-by switch, grant edit and kind-filter toggle; (4) perf — the
+deterministic O(N) `emit`-call count, plus a best-of-3 wall ≥3×.
+
+## [F2] Grouped routes — incremental `contextMap`
+
+```
+cd frontend && npx vitest run src/lib/utils/listContext.bench.test.ts
+```
+
+`/trash`, `/recent`, `/favorites` and `/shared-with-me` each fed `ResourceList`
+a per-item `contextMap` (`id → ItemContext`, carrying the envelope's date /
+owner / drive fields the group-by and row render read) built as
+`$derived(new Map(raw.map((it) => [id, ctx])))` — a brand-new Map re-hashing
+every accumulated id on **every** infinite-scroll page. O(N) per page ⇒ Σ
+O(N²/page) across a drain, and a fresh instance each page invalidated every
+reader. ROUND15 §F1 fixed the `sections` half *inside* `ResourceList`; this is
+the route-level projection that feeds it, flagged on ROUND14's deferred list and
+never landed.
+
+`primeContextPage` (`$lib/utils/listContext`) applies the shipped `favoriteIds`
+shape (ROUND14 §F2, a persistent `SvelteSet` primed per page): each route holds
+one persistent `SvelteMap` for the component's lifetime and, in `load()`, clears
+it on a reset and sets only the freshly-fetched page's entries — O(page) per
+page, O(N) across the drain, one stable instance. The map only ever needs to be
+a superset of the displayed ids (rows removed by a delete aren't rendered, so
+their stale entries are never read), and every id entering `raw` comes through a
+`load()` page, so the map always covers what's on screen. `shared-with-me`
+passes a drive-skipping entry (drives never reach the row UI), so its map
+matches the displayed `fileFolderGrants` exactly.
+
+50×50 drain: **63 750 → 2 500 `entry` calls (25.5× fewer), 7.2× wall**. Gates:
+(1) equivalence — the primed map is deep-equal to a full `new Map(cumulative.map(…))`
+rebuild at every page, including skipped drives and the reset path; (2) perf —
+the deterministic O(N) entry-call count, plus a best-of-3 wall ≥3×.
+
+## [M1]–[M4] Backend CPU/alloc micro-pack
+
+```
+cargo run --release --features bench --example bench_round16_micro
+```
+
+Counting-allocator micro-bench; each section is BEFORE (verbatim replica of the
+shipped-before shape) vs AFTER (the shipped function itself where reachable —
+`intern_display`, `nc_href` — else a verbatim replica of the shipped-after
+shape), with a byte/-value equivalence gate and a `GATE FAIL … rollback` exit.
+
+- **[M1] Folder display constants → interned clone.** The trash-listing
+  (`trash_service.rs`), NC-search-REPORT (`report_handler.rs`) and path-resolver
+  (`path_resolver_service.rs`) folder branches each built
+  `Arc::<str>::from("fas fa-folder")` + `"folder-icon"` + `"Folder"` — three
+  heap allocations + memcpys per folder row — although all three literals are in
+  the `DISPLAY_INTERN` closed set and the **file branch of the very same
+  function** already used `intern_display` (a lookup + refcount bump, 0 allocs).
+  ROUND11 interned the file classifiers on these paths but missed the folder
+  constants. Per trashed / searched / resolved folder row: **3.00 → 0.00
+  allocs/op, 1.14× wall**.
+- **[M2] `build_content_disposition` 3 → 1 alloc.** Called on every download and
+  every Range seek (media/PDF scrubbing pays it per seek), it built a
+  percent-`encoded` String, an `ascii_safe` filtered String, and the `format!`
+  result — 3 allocations. The shipped code fast-paths an all-attr-char name
+  (`filename` and `filename*` are the name verbatim → one `format!`) and, for
+  names needing encoding, writes the ASCII fallback and percent-encoded form
+  into a single pre-sized buffer. Byte-identical across ASCII / spaced / unicode
+  / quote+backslash names: **30.00 → 5.00 allocs/op (6×), 2.67× wall** (5
+  names/op, a fast/slow mix).
+- **[M3] `nc_href` Vec+join → single buffer.** Every NC PROPFIND/REPORT href
+  allocated a per-segment `Vec<Cow>`, a joined String and the `format!` result;
+  the native WebDAV side already fixed this exact shape (`encode_uri_path`). The
+  shipped code writes the prefix, user and each encoded segment straight into one
+  pre-sized buffer, keeping `urlencoding::encode` so the emitted bytes are
+  unchanged (incl. root trailing slash and internal `//`): **38.00 → 27.00
+  allocs/op, 1.44× wall** (5 hrefs/op — the Vec + join + format drop; the
+  per-segment encode Cows, unavoidable, remain).
+- **[M4] NC preview `fileId` borrow-slice parse.** The preview handler
+  `collect()`ed the leading digit run into a String only to reparse it to `i64`;
+  the shipped code finds the digit-prefix length and parses the borrowed slice —
+  0 allocations. Per NC thumbnail request (a gallery fires one per tile): **4.00
+  → 0.00 allocs/op, 2.51× wall** (5 ids/op).
+
+## Not shipped — deferred to a later round
+
+Surfaced by the Round-16 audit but not landed (each wants its own decision,
+Postgres fixture, or a larger change):
+
+- **Backend query-shape (needs Postgres):** carried forward from ROUND15 —
+  `music_storage_adapter::list_public_playlists` 1 + N `COUNT(*)` fold; contact
+  REST listings over-fetching the multi-KB `vcard` TEXT (wants a *lite* row
+  mapper).
+- **Backend CPU/alloc (no Postgres, next micro-pack):** the two WebDAV PROPFIND
+  surfaces still quote `d:getetag` into a fresh String per row and `format!` the
+  per-row href per child (the CalDAV §A6 reused-buffer treatment never reached
+  them); `delta_upload_service` → `hash_chunk_sequence` clones every chunk hash a
+  second time (`.iter().cloned()` on an already-owned Vec — change the signature
+  to take it by value); `contact_to_vcard` seeds from a 27-byte String and
+  `.to_uppercase()`-allocates each TYPE token.
+- **Frontend (vitest-benchmarkable):** `VirtualRows.offsets` prefix-sum is
+  rebuilt in full on every photos-timeline page (residual O(N²) on the hottest
+  scroll surface — an incremental extend needs care to keep the downstream
+  `$derived` reference-invalidation correct); the dotfile filter and
+  `ResourceList.itemIndexById` re-scan the whole accumulated list per page (both
+  conditional — hide-dotfiles on / an active selection — hence lower priority).
+
+## Environment / methodology
+
+- `cd frontend && npx vitest run src/lib/utils/sharedLanes.bench.test.ts`
+  and `… listContext.bench.test.ts` — Node 22 / vitest, no Postgres. Wall gates
+  take the best-of-3 (min) per arm to shrug off scheduler/GC noise under a
+  saturated runner (round14 §F1 pattern); the deterministic O(N) call-count is
+  the primary rollback gate.
+- `cargo run --release --features bench --example bench_round16_micro`
+  — counting allocator, no Postgres (`BENCH_ITERS`).
+- Roll-back rule encoded per harness: the Rust example `std::process::exit(1)`

+## Summary
+
+| # | change | key metric | before → after |
+|--:|---|---|---|
+| **D2** | Chunk-ingest (`store_from_stream`) allocated the 64-char hex hash `String` **3× per chunk** (`to_hex().to_string()` + `chunk_hashes.push(clone)` + `session_seen.insert(clone)` — the last dropped on the spot for a duplicate). The intra-upload dedup set now keys on the raw 32-byte BLAKE3 digest (`[u8; 32]`, `Copy`, no heap), and the manifest push is split so a duplicate **moves** the hex in. | 64-chunk batch, 1-in-2 dup | **214 → 149 allocs/op (65 fewer)** · **1.14× wall** · set clone gone + dup manifest clone gone |
+| **D1** | `hash_chunk_sequence` (delta-commit verification) took `chunks: &[(String,u64)]` and fed the backend stream with `chunks.iter().cloned()` — re-cloning every chunk hash a **second** time on top of the owned `Vec` the caller already built. Take the `Vec` by value and `into_iter()` it. | 64-chunk verify | **65 → 0 internal allocs/op** · **~2.5 µs of clone work removed per verify** |
+| **V1** | `contact_to_vcard` / `generate_vcard` emitted every EMAIL/TEL/ADR `TYPE=` token via `ty.to_uppercase()` — one throw-away `String` per token per contact. New shared `fmt::push_upper` writes the upper-cased chars straight into the vCard buffer. | 8 tokens/op | **13 → 5 allocs/op (8 fewer)** · **1.19× wall** |
+
+> Allocs/op is the deterministic primary gate (identical run to run); the wall
+> figures are single-shot and noise-bounded (D1's AFTER arm is a near-zero-cost
+> read, so its ratio swings 60–120× between runs — the stable fact is the
+> ~2.5 µs / 65-alloc clone removed).
+
+## [D2] Chunk-ingest — dedup set keyed on the raw digest
+
+The streaming ingest loop (`DedupService::store_from_stream`) is the hottest
+write path in the system: it runs for **every chunk of every upload**. Per
+chunk it produced the 64-char hex hash and then allocated it three times:
+
+```rust
+let hash = blake3::hash(&data).to_hex().to_string();   // A: the hex String
+chunk_hashes.push(hash.clone());                        // B: manifest copy  (always)
+if session_seen.insert(hash.clone()) {                  // C: dedup-set copy  (always)
+    pending.push((hash, Bytes::from(data)));            // A moved into the write batch
+}
+```
+
+`session_seen` is the **intra-upload** dedup set (has this exact chunk already
+appeared in *this* stream? — repeated blocks, zero-padded regions, re-chunked
+near-duplicates). It was a `HashSet<String>`, so clone **C** heap-allocated a
+64-byte key for every chunk — and on a duplicate, `insert` allocated the clone
+only to drop it when the key already existed. Pure waste on the case a dedup
+store exists to make cheap.
+
+A BLAKE3 digest is `[u8; 32]` — `Copy`, no heap, and the hex is a lossless
+rendering of it, so keying the set on the raw digest is behaviour-identical:
+
+```rust
+let digest = blake3::hash(&data);
+let hash = digest.to_hex().to_string();                 // A (once)
+if session_seen.insert(*digest.as_bytes()) {            // Copy key — zero heap
+    chunk_hashes.push(hash.clone());                     // B (new chunk only)
+    pending.push((hash, Bytes::from(data)));             // A moved
+} else {
+    chunk_hashes.push(hash);                             // dup: move, no clone
+}
+```
+
+Clone **C** is gone for every chunk; clone **B** is gone for every *duplicate*
+(it moves the hex into the manifest instead). The set also holds 32-byte inline
+keys instead of 64-byte heap Strings and hashes 32 bytes per membership test.
+Net per chunk: **3 → 2 allocs (new) / 3 → 1 (duplicate)** — strictly fewer on
+every input, unique or duplicate.
+
+64-chunk, 1-in-2-duplicate batch: **214 → 149 allocs/op (65 fewer), 1.14×
+wall**. Gate (in-harness, replica of the exact before/after loop bodies): the
+observable output is **byte-for-byte equal** — the ordered `chunk_hashes`
+manifest, the `chunk_sizes`, and the distinct write-set `pending` all match;
+only the private set's key representation differs — plus the `gate_allocs`
+rollback exit on any AFTER that fails to reduce allocations.
+
+## [D1] `hash_chunk_sequence` — take the chunk Vec by value
+
+The delta-sync commit (`delta_upload_service::commit`) verifies a client's
+proposed manifest by streaming the pinned chunks back out of the backend and
+recomputing the whole-file BLAKE3. The caller already builds a fresh owned
+`Vec<(String,u64)>` (`request.chunks.iter().map(|c| (c.h.clone(), c.s)).collect()`),
+but `hash_chunk_sequence` took it by `&[(String,u64)]` and then did
+`futures::stream::iter(chunks.iter().cloned())` — **re-cloning every chunk hash
+a second time** to feed the stream.
+
+Taking `chunks: Vec<(String,u64)>` by value and `into_iter()`-ing it (the caller
+drops one `&`) moves those Strings straight into the stream: zero internal
+clones. The streamed `(hash, size)` pairs are byte-identical, so the recomputed
+hash and every per-chunk size check are unchanged.
+
+The section isolates exactly the clone the old signature forced (the caller's
+`.collect()` is identical on both shapes and excluded): **65 → 0 allocs/op** for
+a 64-chunk manifest — ~2.5 µs of clone work removed per verify (the AFTER arm is
+a near-zero-cost read, so the wall ratio is large but noisy: 60–120×). Gate: the
+old internal clone is asserted to be a pure copy (moving changes nothing
+observable), plus `gate_allocs`.
+
+## [V1] CardDAV vCard `TYPE=` tokens — `push_upper`
+
+Both vCard emitters — `carddav_adapter::contact_to_vcard` (the CardDAV
+REPORT/GET path) and `ContactService::generate_vcard` — wrote each address /
+phone / email `TYPE=` parameter with `write!(…, "{}", ty.to_uppercase())`, and
+`str::to_uppercase()` heap-allocates a fresh `String` for every token. A contact
+with several emails/phones/addresses pays one alloc per token, per emit, on
+every address-book sync.
+
+New shared helper `common::fmt::push_upper(buf, s)` writes the upper-cased chars
+(`char::to_uppercase`, so byte-identical to `str::to_uppercase` — including
+ß → SS and dotless-i) straight into the vCard buffer; the five call sites push
+the fixed prefix, the upper-cased token, and the value directly. Zero
+temporaries.
+
+8-token contact: **13 → 5 allocs/op (8 fewer), 1.19× wall**. Gates:
+`push_upper` is unit-tested byte-equal to `str::to_uppercase` across ASCII /
+mixed / multi-char-uppercase / dotless-i inputs (`fmt::tests`), the section
+asserts the full emitted vCard is byte-identical before/after, and the existing
+`carddav_adapter_test::test_contact_to_vcard_full` pins the whole document.
+
+## Not shipped — deferred to a later round
+
+Surfaced during the Round-17 audit but not landed (each wants its own decision,
+a Postgres fixture, or a streaming-I/O benchmark):
+
+- **Storage I/O — `encrypted_blob_backend` frame size (evaluated, kept):** the
+  ROUND15 note floated 64 KiB → 256 KiB plaintext emit frames. `PLAINTEXT_EMIT_SIZE`
+  is a *deliberate* match to the 64 KiB the unencrypted backends stream, so
+  downstream consumers see the same backpressure shape; changing it is a
+  behaviour change that needs a streaming-throughput A/B (TTFB + syscalls +
+  peak RSS), not an alloc micro-bench. Left as-is pending that harness.
+- **Storage I/O — `CachedBlobBackend` write path (needs an fs harness):**
+  per-write `create_dir_all` even when the shard dir exists, and inline
+  eviction `remove_file` on the reactor thread (carried from ROUND15).
+- **Backend query-shape (needs Postgres):** `music_storage_adapter::list_public_playlists`
+  1 + N `COUNT(*)` fold; contact REST listings over-fetch the multi-KB `vcard`
+  TEXT though the `ContactDto` mappers never read it (wants a *lite* row mapper).
+- **Backend CPU/alloc (no Postgres, next micro-pack):** the two WebDAV PROPFIND
+  surfaces still quote `d:getetag` into a fresh `String` per row and `format!`
+  the per-row href per child (the CalDAV reused-buffer treatment never reached
+  them); REST calendar-event edit re-`format!`s the whole `ical_data` body once
+  per changed property.
+- **Frontend (vitest-benchmarkable):** `VirtualRows.offsets` prefix-sum rebuilt
+  in full on every photos-timeline page; the dotfile filter and
+  `ResourceList.itemIndexById` re-scan the whole accumulated list per page.
+
+## Environment / methodology
+
+- `cargo run --release --features bench --example bench_round17_micro`
+  — counting global allocator, no Postgres. Tunables: `BENCH_ITERS` (100000),
+  `BENCH_CHUNKS` (64), `BENCH_DUP_RATIO` (2).
+- Each section is BEFORE (verbatim replica of the shipped-before shape) vs AFTER
+  (verbatim replica of the shipped-after shape) with a byte/-value equivalence
+  gate; the shipped source now matches each AFTER arm.
+- Roll-back rule encoded per section: `std::process::exit(1)` with
+  `GATE FAIL … rollback` if an AFTER arm fails to reduce allocations.

+# Round 18 — calendar-event in-place iCal edit, ResourceList incremental id-index
+
+Benchmark-gated, same rule as ROUND2–17: every change ships with a
+BEFORE/AFTER benchmark and an equivalence/safety gate; an AFTER that doesn't
+beat its BEFORE is rolled back (never applied). The roll-back rule is encoded
+directly into each harness — a `GATE FAIL … rollback` non-zero exit (Rust) or a
+failing `expect(afterMs).toBeLessThan(beforeMs / K)` assertion (vitest) — so a
+regression fails CI rather than shipping.
+
+This round picks up two items carried on the **ROUND17 deferred list**:
+
+- the **REST calendar-event edit** that re-`format!`'d the whole `ical_data`
+  body once per changed property (backend, no Postgres — counting-allocator
+  example), and
+- **`ResourceList.itemIndexById`**, which re-scanned the whole accumulated list
+  per infinite-scroll page (frontend, vitest-benchmarked).

+## Summary
+
+| # | change | key metric | before → after |
+|--:|---|---|---|
+| **C1** | `CalendarEvent::update_ical_property` / `remove_ical_property` rewrote the ENTIRE `ical_data` body with `format!("{}{}{}")` on every call and allocated **two** search needles per call (`\nNAME:` + the redundant `\r\nNAME:`). `calendar_storage_adapter::update_event` fans a multi-field edit out into one `update_ical_property` per changed field, so a full edit paid one full-body (up to ~11 KB) allocation **per property**. Now the body is mutated in place (`replace_range` for an existing property, four `insert`/`insert_str` for a new one) and the single `\nNAME:` needle is built on the stack. | 9-op edit, 1187-byte body | **70 → 2 allocs/op (68 fewer, ~35×) · 2.46× wall** (4255 → 1727 ns/op) |
+| **F1** | `ResourceList` derived `itemIndexById = new Map(items.map((i,idx)=>[i.id,idx]))` — a fresh Map over the WHOLE accumulated list every infinite-scroll page (O(N)/page, Σ O(N²)), and being a new instance each page it also re-fired the reap-stale `$effect` (another O(N) id `Set`/page for a reap an append can never cause). New `ItemIndexBuilder` extends a persistent Map with the fresh page only and reuses the reference across appends. | 40 pages × 50 | **74.1 → 6.4 ms · 11.5× faster** index build across the drain |
+
+## [C1] calendar-event edit — in-place iCal property rewrite
+
+`calendar_storage_adapter::update_event` hydrates the stored event, then applies
+each present field of the `UpdateEventDto` independently:
+
+```rust
+if let Some(summary) = update.summary { event.update_summary(summary)?; }
+if let Some(description) = update.description { event.update_description(Some(description)); }
+if let Some(location) = update.location { event.update_location(Some(location)); }
+// …start/end (update_time_range), all_day (rewrites DTSTART+DTEND again), rrule…
+```
+
+Every one of those funnels into `CalendarEvent::update_ical_property` (an absent
+field cleared → `remove_ical_property`), and the shipped-before body of that
+method rebuilt the **entire** `ical_data` String on each call:
+
+```rust
+let search_str     = format!("\n{}:", property_name);     // needle 1
+let search_str_alt = format!("\r\n{}:", property_name);   // needle 2 (redundant)
+let pos = self.ical_data.find(&search_str).or_else(|| self.ical_data.find(&search_str_alt));
+// …
+let before = &self.ical_data[..value_start];
+let after  = &self.ical_data[value_end..];
+self.ical_data = format!("{}{}{}", before, value, after);  // a whole fresh body String
+```
+
+So a REST edit that changes summary + description + location + start + end +
+all-day + rrule allocated **one full-body String per property** — and calendar
+bodies run to ~11 KB once attendees / VALARMs are present — plus two throwaway
+needles per call.
+
+Two observations drive the fix:
+
+1. **The `\r\nNAME:` needle is redundant.** `\nNAME:` is a *suffix* of
+   `\r\nNAME:`, so `find("\nNAME:")` already matches a CRLF-terminated property
+   line (returning the `\n` offset) — the `.or_else(find("\r\nNAME:"))` branch
+   can never be reached. One needle suffices, and since iCal property names are
+   short ASCII it is built into a 64-byte **stack** buffer (`line_needle`) — zero
+   heap needle.
+2. **The rewrite can be in place.** `replace_range(value_start..value_end, value)`
+   is byte-for-byte what `before + value + after` produced, but it mutates the
+   body's own buffer (growing once only when the new value is longer) instead of
+   allocating a fresh body. The absent-property branch inserts the four pieces at
+   one point in reverse (`\n`, value, `:`, name) after a single `reserve`, so a
+   new property costs no fresh-body and no value-sized fragment either.
+
+Because both arms edit the **same byte spans**, the emitted body is identical —
+including the pre-existing quirk that editing a line on a CRLF body drops that
+line's `\r` (the old span already included it; `replace_range` over the same
+span preserves the behaviour exactly). The bench's equivalence gate asserts the
+full 9-op edit is byte-identical, and the existing `calendar_event` unit tests
+(`update_summary` / `update_time_range` / `update_all_day` round-trips) pin the
+observable semantics.
+
+Measured (`bench_round18_micro`, counting allocator, no Postgres). Both arms pay
+one identical `base.to_string()` reset per op (a shared constant), so the
+**fewer-allocs** figure is the pure per-edit saving.
+
+```
+## [C1] calendar-event multi-field edit (9 ops, 1187-byte body)
+| arm                                            |        ns/op | allocs/op |
+| BEFORE update_event in-place property rewrite  |       4255.4 |     70.00 |
+| AFTER  update_event in-place property rewrite  |       1726.5 |      2.00 |
+# 2.46x wall, 68.00 fewer allocs/op
+```
+
+The AFTER arm's two allocations per whole 9-op edit are the shared
+`base.to_string()` reset and a single buffer grow (the longer DESCRIPTION value +
+the inserted RRULE), versus 70 for the old per-property `format!` fan-out — a
+35× cut, byte-identical output.
+
+## [F1] ResourceList `itemIndexById` — incremental id→index Map
+
+`ResourceList` pages its list in via infinite scroll (`items = [...items,
+...page]`) and derived, on every change:
+
+```js
+const itemIndexById = $derived(new Map(items.map((i, idx) => [i.id, idx])));
+```
+
+`selectedItems` reads that Map to project the current selection in list order.
+The derive is a full O(N) rebuild of a **fresh** Map over the whole accumulated
+list every page — Σ O(N²) across a P-page drain with a selection active — and,
+being a new instance each page, it also re-fired the reap-stale `$effect` (which
+reference-diffs it), and that effect built *another* throwaway O(N) `Set` of ids
+per page for a reap that an append can never trigger (an append only adds ids).
+
+`ItemIndexBuilder` (new, `$lib/utils/itemIndex.ts`, mirroring
+`ResourceSectionsBuilder`) uses the shared O(1) `isAppendExtension` witness: on
+an append it indexes only the fresh tail into a persistent Map and returns the
+**same reference**; any other change (reload, deletion, non-append) rebuilds into
+a **new** Map. That reference contract is exactly what the two consumers want:
+
+- `selectedItems` re-derives on every `items` change regardless (it indexes
+  `items[idx]`), so it always reads the freshly-extended Map — a stable
+  reference on append costs it nothing;
+- the reap-stale `$effect` now tests membership against that Map instead of a
+  fresh `Set`, and a stable reference on append means it **doesn't re-run** there
+  (nothing to reap) while a rebuild — the delete/reload case — yields a new
+  reference and **does** re-run it, precisely when stale ids must be dropped.
+
+Gates (`round18.bench.test.ts`): the builder is asserted deep-equal to the
+verbatim `buildItemIndex` reference at **every** page of a 12-page drain (and on
+the final index of a 20-page one), a later duplicate id resolves to its highest
+index (matching `Map`'s last-wins), and the reference-contract gate pins
+same-ref-on-append / new-ref-on-rebuild. The perf gate requires the incremental
+drain to beat the rebuild-per-page by ≥5×.
+
+Measured: a 40-page × 50-item drain builds the index in **6.4 ms vs 74.1 ms —
+11.5× faster** — and no longer churns a fresh Map + id-Set per page.
+
+## Not shipped — deferred to a later round
+
+Surfaced during the Round-18 audit but not landed (each needs its own decision,
+fixture, or a different reactivity treatment):
+
+- **Frontend — flat dotfile filter (`ResourceList` inline `items.filter` +
+  `utils/dotfileFilter::filterDotfiles`, on photos):** the ROUND17 note flagged
+  it as an O(N²) per-page rescan when *hide dotfiles* is on. Unlike the favorites
+  `Set` (ROUND14 §F2) or this round's id-`Map`, the filtered result is a **flat
+  array** that feeds `.filter`/rendering — reactivity needs a *fresh* array
+  reference each page, and building one by `prev.concat(freshFiltered)` is itself
+  O(N) (a mutate-in-place same-reference array would stop `photoRows` /
+  `visibleItems` consumers from recomputing). There is no clean O(N)→O(page) win
+  without partitioning the list; deferred pending a design (e.g. filtering per
+  page in the loader and accumulating in page state, which changes the
+  toggle-refilter semantics).
+- **Frontend — `VirtualRows.offsets` prefix-sum (photos timeline):** rebuilt in
+  full per page. An incremental prefix-sum needs (a) a version-counter to force
+  `band`/`totalHeight` to recompute without a fresh `offsets` array reference
+  (Svelte deriveds short-circuit on `===`), and (b) `PhotoTimeline` to guarantee
+  row-object identity at the append boundary (a page that grows the last group
+  re-lays-out its trailing strip row, breaking `isAppendExtension`). Both are
+  real but want their own round; the raw numeric prefix-sum is also cheap (rows ≪
+  photos), so this is lower-priority than the item-list rescans.
+- **Backend query-shape (needs Postgres, carried from ROUND17):**
+  `music_storage_adapter::list_public_playlists` 1 + N `COUNT(*)` fold; contact
+  REST listings over-fetch the multi-KB `vcard` TEXT the `ContactDto` mappers
+  never read (wants a *lite* row mapper).
+
+## Environment / methodology

+Benchmark-gated, same rule as ROUND2–18: every change ships with a BEFORE/AFTER
+benchmark and an equivalence/safety gate; an AFTER that doesn't beat its BEFORE
+is rolled back (never applied). The roll-back rule is encoded directly into the

+(`JwtTokenService`'s prebuilt keys, `common::fmt`'s stack date renderers, the

+## Summary
+
+| # | change | key metric | before → after |
+|--:|---|---|---|
+| **M1** | `AppPasswordService::verify_basic_auth` built the moka cache key as `blake3::hash(format!("{username}:{password}").as_bytes())` — one throwaway `String` per **Basic-auth request** (runs before the cache lookup, so even hits pay it; DAV sync clients hammer it on every request). Now streamed into an incremental `blake3::Hasher` — byte-identical 32-byte key. | 20-byte creds | **2 → 0 allocs/op · 1.66× wall** (182.0 → 109.4 ns) |
+| **M2** | `WopiTokenService::validate_token`/`generate_token` rebuilt a `Validation` (allocates a `required_spec_claims` HashSet + `algorithms` Vec) and a `DecodingKey`/`EncodingKey` (copies the secret into a fresh Vec) on **every WOPI call** — Office/Collabora poll continuously. Now all three are prebuilt struct fields in `new()` (exactly what `JwtTokenService` already does). | HS256 validate | **16 → 12 allocs/op · 1.07× wall** |
+| **V1** | `contact_to_vcard`/`generate_vcard`, **per contact** in every CardDAV REPORT/multiget/PROPFIND-with-address-data: FN fallback dropped the throwaway `.to_string()` copy of the trim slice; NOTE `replace('\n', "\\n")` is now guarded (`contains('\n')`) so a newline-free note writes borrowed; REV `.format("%Y%m%dT%H%M%SZ")` → `common::fmt::compact_ical_utc`. | full vCard emit | **9 → 4 allocs/op · 1.97× wall** (548.2 → 277.7 ns) |
+| **V2** | The REV/DTSTAMP stamp isolated: chrono `.format("%Y%m%dT%H%M%SZ")` runs the strftime interpreter and (measured) **allocates 3×** per call; the new `common::fmt::compact_ical_utc` renders `YYYYMMDDTHHMMSSZ` into a 16-byte stack buffer via the shared `push2`/`push4` LUT. | one stamp | **3 → 0 allocs/op · 11.77× wall** (216.9 → 18.4 ns) |
+| **M4** | `trash_service::row_to_item_dto` `clone()`d `name`/`path`/`blob_hash` out of an **owned** `row` that is dropped at fn end — 2 clones/folder row, 3/file row, up to 200 rows/`/api/trash` page. Now moved (the favorites/recent/folder mappers already move these). | file row | **10 → 7 allocs/op** (3 clones gone) |
+| **M5** | `SearchUseCase::search` built the cache-key user segment via `user_id.to_string()` — one heap `String` **per search request** to feed a hasher the fn doc even calls "zero-allocation". Now stack-encoded via `Uuid::hyphenated().encode_lower(&mut [u8; 36])`; byte-identical string ⇒ identical u64 key. | 1 request | **1 → 0 allocs/op · 1.30× wall** |
+| **M6** | Streaming WebDAV **PROPFIND** built each child `href` with a fresh `format!` per row — up to 500 rows/page, 4 loops across the native + NextCloud handlers, the single most-travelled DAV path. Now one buffer reused across the page (`clear` + `push_str` + `extend`/`push_str`). | 64-child page | **192 → 3 allocs/op · 2.74× wall** (10.9 → 4.0 µs) |
+| **M7** | `nextcloud::session::extract_url_user` forced `.into_owned()` on the `urlencoding::decode` `Cow` on **every path-scoped NC DAV request**, though a plain-ASCII username decodes to `Cow::Borrowed`. Now returns the `Cow` and compares by `.as_ref()`. | ASCII user | **1 → 0 allocs/op · 3.11× wall** (25.5 → 8.2 ns) |
+
+> Allocs/op is the deterministic primary gate (identical run to run). Wall
+> figures are single-shot and noise-bounded; §V2 is the one CPU-only arm (both
+> emit the same 0 allocs after the fix is measured against chrono's 3) and is
+> gated on a ≥2× wall ratio — it clears it with 11.8×.
+
+## [M1] Basic-auth cache key — incremental hasher
+
+`verify_basic_auth` runs on every WebDAV/CalDAV/CardDAV/NextCloud request that
+carries Basic auth — and DAV sync clients (DAVx5, Apple, Thunderbird, the
+Nextcloud desktop client) send credentials on **every** request, holding 4–8
+parallel connections. The cache key is computed *before* the single-flight cache
+lookup, so it runs on hits too:
+
+```rust
+let cache_key: [u8; 32] =
+    blake3::hash(format!("{}:{}", username, password).as_bytes()).into();
+```
+
+The `format!` heap-allocates one `String` per request purely to concatenate the
+two parts before handing the bytes to blake3. blake3 is a **streaming** hash —
+feeding `username`, then `":"`, then `password` into an incremental `Hasher`
+produces the identical digest with no intermediate buffer:
+
+```rust
+let cache_key: [u8; 32] = {
+    let mut h = blake3::Hasher::new();
+    h.update(username.as_bytes());
+    h.update(b":");
+    h.update(password.as_bytes());
+    h.finalize().into()
+};
+```
+
+The bench's equivalence gate asserts the two 32-byte keys are identical, so
+in-flight and cached entries collide exactly as before. **2 → 0 allocs/op,
+1.66× wall** — and note the `format!` version's *second* alloc is the
+`String`'s grow, both gone.
+
+## [M2] WOPI token validate/generate — prebuilt keys
+
+`WopiTokenService` mirrored none of the prebuilt-key discipline
+`JwtTokenService` adopted in an earlier round. Every `validate_token` (6 WOPI
+handler entry points — CheckFileInfo, GetFile, PutFile, Lock, …, polled
+continuously by the Office/Collabora host during an edit session) rebuilt:
+
+```rust
+let validation = Validation::new(Algorithm::HS256);      // HashSet + Vec
+let token_data = decode::<WopiTokenClaims>(
+    token,
+    &DecodingKey::from_secret(self.secret.as_bytes()),   // fresh Vec copy of the secret
+    &validation,
+)…
+```
+
+`Validation::new` inserts `"exp"` into a fresh `required_spec_claims` HashSet and
+allocates an `algorithms` Vec; `DecodingKey::from_secret` copies the secret into
+a new Vec. `generate_token` did the same with `EncodingKey::from_secret`. All
+three are now built once in `new()` and stored as fields:
+
+```rust
+pub struct WopiTokenService {
+    encoding_key: EncodingKey,
+    decoding_key: DecodingKey,
+    validation: Validation,
+    token_ttl_secs: i64,
+}
+```
+
+The `secret` field is dropped — nothing else read it. **16 → 12 allocs/op** on
+validate (the remaining 12 are the JWT crate's own base64/JSON claim
+deserialization, paid by both arms). The four removed are exactly the
+`Validation` HashSet + its `"exp"` String + the `algorithms` Vec + the
+`DecodingKey` secret-copy. Existing `wopi_token_service` unit tests
+(generate→validate round-trip, wrong-secret reject, read-only) pin the behaviour.
+
+## [V1]/[V2] vCard per-contact emit — FN, NOTE, and the REV stamp renderer
+
+`contact_to_vcard` (`carddav_adapter.rs`) and its twin `generate_vcard`
+(`contact_service.rs`) emit one vCard **per contact** in every CardDAV REPORT,
+`addressbook-multiget`, and collection PROPFIND that requests `address-data`
+(i.e. every real DAVx5 / Apple Contacts / Thunderbird sync). Three per-contact
+allocations:
+
+1. **FN fallback** (`full_name` absent) built the mandatory `FN` from the
+   name parts and copied the trimmed slice into a second owned `String`:
+   ```rust
+   let fn_name = format!("{} {}", first, last).trim().to_string();
+   ```
+   The `.to_string()` is redundant — `write!(vcard, "FN:{}\r\n", fn_name.trim())`
+   writes the borrowed slice straight into the buffer. (The `format!` is kept:
+   trimming *across* the join is subtle, and this arm is a fallback; dropping the
+   copy is the unambiguously byte-identical win.)
+
+2. **NOTE** ran `notes.replace('\n', "\\n")` unconditionally — a full copy of the
+   note even when it has no newline (the common case), then formatted into the
+   buffer and dropped. Now guarded: a newline-free note writes its borrowed slice
+   directly; only a genuine multi-line note pays the escaping copy.
+
+3. **REV** ran chrono's `updated_at.format("%Y%m%dT%H%M%SZ")` — and §V2 shows
+   that `DelayedFormat` **allocates 3×** (not the 0 first assumed) while running
+   the strftime spec interpreter. The new `common::fmt::compact_ical_utc(buf,
+   secs)` renders the compact iCal/vCard UTC form `YYYYMMDDTHHMMSSZ` into a
+   16-byte **stack** buffer via the same `push2`/`push4` LUT the RFC-3339/2822
+   renderers use, falling back to chrono for out-of-range seconds.
+
+Isolated (§V2), the stamp renderer is **11.77× faster and 3 → 0 allocs**
+(216.9 → 18.4 ns). Over the whole per-contact emit (§V1, a contact exercising all
+three shapes) that is **9 → 4 allocs/op, 1.97× wall** (548.2 → 277.7 ns). Both
+`updated_at` fields are `DateTime<Utc>`, so `compact_ical_utc(ts.timestamp())` is
+byte-for-byte the chrono output; `common::fmt`'s existing chrono-parity sweep
+(every 6h13m across 60 years) now covers `compact_ical_utc` too.
+
+## [M4] trash row → DTO — move, don't clone
+
+`row_to_item_dto` takes an **owned** `TrashResourceRow` (consumed, dropped at fn
+end) yet cloned its `String` fields into the DTO — `path` and `name` on a folder
+row, plus `blob_hash` and `name` on a file row — up to 200 rows per
+`GET /api/trash/resources` page:
+
+```rust
+let path = row.path.clone().unwrap_or_default();
+…
+name: row.name.clone(),
+…
+let content_hash = row.blob_hash.clone().unwrap_or_default();
+```
+
+Because `row` is owned, each field can be **moved** (`row.path.unwrap_or_default()`,
+`name: row.name`, `row.blob_hash.unwrap_or_default()`). This is precisely what the
+sibling `favorites_handler` / `recent_handler` / `folder_handler` row mappers
+already do (with explicit "move it instead of cloning" comments); the trash path
+was simply missed. **10 → 7 allocs/op** on the file branch (the remaining 7 are
+`id.to_string()`, the interned display fields, and the `File::compute_etag`
+stand-in — all unavoidable).
+
+## [M5] search cache key — stack-encode the UUID
+
+`SearchUseCase::search`'s `create_cache_key` hashes the criteria + a `&str`
+user id; the caller fed it `user_id.to_string()`:
+
+```rust
+let user_id_str = user_id.to_string();                       // heap, per request
+let cache_key = Self::create_cache_key(&criteria, &user_id_str);
+```
+
+`Uuid::hyphenated().encode_lower(&mut [u8; 36])` writes the identical 36-char
+lowercase form into a **stack** buffer, so the hasher sees the same bytes ⇒ the
+same `u64` key — the equivalence gate asserts it — with no allocation. The fn's
+own doc-comment already claimed "zero-allocation hashing"; this makes it true.
+**1 → 0 allocs/op.**
+
+## [M6] streaming PROPFIND per-child href — one reused buffer
+
+The streaming folder PROPFIND is the single most-travelled WebDAV path (every
+folder listing, every desktop-sync descent). Both the native
+(`webdav_handler.rs`) and NextCloud (`nextcloud/webdav_handler.rs`) handlers
+built each child's `href` with a fresh `format!` per row — 4 loops, each up to
+`PROPFIND_BATCH_SIZE` (500) rows/page:
+
+```rust
+for file in batch.iter() {
+    let href = format!("{}{}", base_href, utf8_percent_encode(&file.name, …));
+    …
+}
+```
+
+One `String` per child. A single buffer hoisted out of the loop and rebuilt in
+place (`href.clear(); href.push_str(base); href.extend(encode(name));`) keeps
+its capacity across the page — the CalDAV/CardDAV emitters already thread reused
+`href`/`etag` buffers exactly this way. On a 64-child page: **192 → 3 allocs/op,
+2.74× wall** (10.9 → 4.0 µs); the 3 remaining are the buffer's initial grows to
+the widest href. The equivalence gate asserts the emitted href set is
+byte-identical.
+
+## [M7] NextCloud `extract_url_user` — keep the Cow
+
+Every path-scoped NC DAV request (`/remote.php/dav/{files,uploads,trashbin}/
+{user}/…`) cross-checks the URL `{user}` segment against the session's
+`raw_username`. The extractor forced an owned `String`:
+
+```rust
+urlencoding::decode(user_seg).ok().map(|s| s.into_owned())
+```
+
+`urlencoding::decode` returns `Cow::Borrowed` for a username with no
+percent-escapes (the overwhelming common case), so `.into_owned()` allocates a
+`String` on every request for nothing. Returning the `Cow` and comparing
+`url_user.as_ref() != session.raw_username.as_str()` is zero-alloc on the common
+path; only a percent-encoded username owns. **1 → 0 allocs/op, 3.11× wall.**
+
+## Not shipped — deferred to a later round
+
+Surfaced during the Round-19 audit but not landed (each needs Postgres, a
+schema/DTO change, or its own decision):
+
+- **CardDAV vCard etag buffer (`carddav_adapter::write_contact_response`):** the
+  quoted `getetag` allocates a `String` per contact; the CalDAV emitter threads a
+  reused `&mut String` etag buffer across the page but CardDAV's
+  `write_contacts_report_page` never got the equivalent. Wants the buffer threaded
+  through `write_contact_response` / `write_collection_contact_page` — a
+  multi-signature change, deferred to keep this round's diff per-item-local.
+- **CardDAV whole-book GET buffer (`carddav_handler::handle_get`):** the
+  `text/vcard` export accumulates into a `String::new()` (repeated grows) and
+  each `contact_to_vcard` allocates a per-contact throwaway `String` copied into
+  it. Wants a `write_vcard_into(&mut String, …)` variant so the per-contact
+  String disappears — an API addition, deferred.
+- **BDAY stamp (`%Y-%m-%d` / `%Y%m%d`):** a `NaiveDate` date-only analogue of
+  `compact_ical_utc`; only fires for contacts-with-birthday, so lower-priority
+  than REV (every contact). A `compact_date` helper is the natural follow-up.
+- **Search `suggest` DTO over-build (`search_service::suggest_with_perms`):**
+  builds a full `FileDto`/`FolderDto` per candidate (≤20) on every keystroke only
+  to copy out 5 fields — `size_formatted`/`content_hash`/`etag` are computed and
+  dropped. Wants the fields pulled off the entity directly; deferred pending a
+  small helper to avoid duplicating the display classifiers.
+- **`grant_handler` shared-with-me deep clone (needs Postgres to bench the full
+  path):** each shared item does `resource_id.to_string()` to key a map and a
+  full DTO `.clone().without_hierarchy_info()`; a `remove`-and-move is valid only
+  if summaries hold unique resource ids — verify before applying.
+
+## Environment / methodology
+
+- `cargo run --release --features bench --example bench_round19_micro` —
+  counting global allocator, no Postgres. Tunable: `BENCH_ITERS` (200000; §M6
+  uses a smaller default as each op is a whole 64-child page).
+- Each section is BEFORE (verbatim replica of the shipped-before shape) vs AFTER
+  (the shipped function itself where reachable — `common::fmt::compact_ical_utc`,
+  `push_upper` — else a verbatim replica of the shipped-after shape), with a
+  byte/-value equivalence gate; the shipped source now matches each AFTER arm.
+- Roll-back rule encoded per section: the harness `std::process::exit(1)`s with
+  `GATE FAIL … rollback` if an AFTER arm fails to reduce allocations (§M1, M2, V1,
+  M4, M5, M6, M7) or, for the CPU-only §V2 stamp, fails to beat BEFORE by ≥2×
+  wall. All eight sections pass.

+
+Five backend changes + one frontend change, each gated by a before/after
+benchmark (`examples/bench_round2.rs`; frontend gate in

+## [1] Range requests served from the content cache — 2,156×
+
+Media players and PDF viewers fetch files *exclusively* via Range requests
+(a `bytes=0-` probe, then seeks). All three range paths (REST, DAV helper,
+public shares) went straight to `get_file_range_stream`: a PG blob-hash
+resolve + chunk open/seek/read per seek — even when the whole sub-10 MB blob
+sat in the moka content cache as contiguous `Bytes`.
+`FileRetrievalService::get_file_range_preloaded` now answers from the cache
+(`Bytes::slice` = refcount bump; a miss populates it via the same
+single-flight loader Tier 1 uses, so one probe warms every later seek).

+
+## [2] NC chunked-upload gate: O(N²) directory scan → O(1) counter — 357×
+
+`handle_put_chunk` recomputed "session bytes so far" on EVERY chunk PUT by
+listing the session directory and stat-ing every existing chunk — chunk k
+scans k files; a 1,000-chunk (10 GB) upload does ~500k stats.
+`NextcloudChunkedUploadService` now keeps an in-RAM per-session counter
+(seeded on MKCOL, bumped per accepted chunk, dropped on cleanup/overwrite,
+lazily rebuilt from the listing on cold start — crash semantics unchanged).
+
+Cumulative gate cost across a 1,000-chunk upload: **33,063 ms → 93 ms**.
+
+## [3] Delta download / commit-verify read-ahead — 8.7× (latency-bound)
+
+`delta_download_chunks` and `hash_chunk_sequence` drained chunks strictly
+sequentially — every chunk-open's round-trip paid serially — while the main
+CDC download path already overlaps opens with `buffered(read_prefetch)`.
+Both now use the same combinator (order preserved — `buffered` yields in
+input order).
+
+64-chunk drain with 5 ms per-open latency (object-store model):
+**440 ms → 51 ms**. On local disk the same combinator measured +7–12 %
+(benches/BLOB-PREFETCH.md).
+
+## [4] CDC ingest: settle overlapped with reading — +7–25 %
+
+`ingest_chunks_from_stream` awaited each batch settle (PG pin round-trip +
+up to 8 MiB of backend writes) INLINE — the HTTP source was not polled at
+all during the settle, so read and settle phases alternated instead of
+overlapping. The settle now runs on a spawned task (depth-1 pipeline) that
+records into the guard's shared, lock-serialized state — rollback stays
+exact even if the request future is dropped mid-settle.
+`OXICLOUD_INGEST_OVERLAP=0` restores the inline behaviour (the bench's
+BEFORE side, and an ops escape hatch).
+
+512 MiB unique-content ingest, source paced at 300 MB/s, two reps:
+**60 / 69 MB/s (inline) → 75 / 74 MB/s (overlapped)**.
+
+## [5] Streaming ZIP: constant time-to-first-byte — 779× on this corpus
+
+`create_folder_zip` built the ENTIRE archive into a temp file before the
+handler sent byte one — TTFB grew with folder size (a multi-GB folder =
+minutes of "waiting for server"). `create_folder_zip_stream` plans inline
+(planning errors still surface as proper HTTP errors), then writes the
+archive on a spawned task through `tokio::io::duplex`, streaming bytes as
+they are produced. Folder downloads and public-share ZIPs both use it; a
+mid-archive blob error truncates the stream (no central directory → clients
+detect corruption) — the standard streamed-ZIP tradeoff. Content-Length is
+no longer sent (size unknown up front).
+
+48 × 4 MiB media corpus: TTFB **326.1 ms → 0.4 ms**; total wall also
+improved (484 ms → 55 ms — no disk round-trip through the temp file).
+TTFB in BEFORE scales linearly with archive size; AFTER is constant.
+
+## [6] Frontend: instant-upload hashing on a worker pool
+
+`resolveOwnedHashes` hashed every small file of a drop sequentially on the
+MAIN THREAD (synchronous WASM BLAKE3 per file) before any upload lane
+started — seconds of UI jank on large drops. Hashing now fans out over a
+bounded pool of dedicated Web Workers (`static/workers/hashWorker.js`,
+`File` handles passed by reference, reads happen inside the worker), with
+the old inline loop kept as fallback where `Worker` is unavailable.
+
+Architecture gate (node worker_threads, read+hash 24 × 4 MiB, file
+references — faithful to the browser shape): 3-lane pool beats the
+sequential loop; asserted by `deltaUpload.hash.test.ts` so a regression
+fails CI. First model of this gate (posting BUFFERS instead of file
+references) was 2.6× SLOWER — structured-clone copies dominated — and was
+rewritten; kept here as a reminder that the gate must model the real
+data-flow.
+
+## Skipped this round
+
+- **Swimlane (group-by) view virtualization** — needs interactive browser
+  measurement (frame times while scrolling) that this environment can't
+  produce; deferred rather than shipped unverified.

+# Round 20 — parse-path HashMap purge, owned-DTO moves, Result-collect pre-size, NC etag/favorites emit
+
+Benchmark-gated, same rule as ROUND2–19: every change ships with a BEFORE/AFTER
+benchmark and a byte/-value equivalence gate; an AFTER that doesn't beat its
+BEFORE is rolled back (never applied). The roll-back rule is encoded directly in
+the harness — a `GATE FAIL … rollback` non-zero exit if an AFTER arm fails to
+reduce allocations — so a regression fails CI rather than shipping.
+
+This round drains three seams the earlier passes left: the **inbound parse
+paths** (CalDAV iCal, CardDAV vCard) that rounds 4–19 optimized on the *emit*
+side but not on ingest; three **owned-entity → DTO conversions** that the
+`into_parts` move-not-clone rounds skipped (`User`, `Calendar`, `AddressBook`);
+and a **stdlib footgun** — `collect::<Result<Vec<_>, _>>()` never pre-sizes — on

+## Summary
+
+| # | change | key metric | before → after |
+|--:|---|---|---|
+| **A1** | `CalendarEvent::prop_with_params` built a throwaway `HashMap<String, Vec<String>>` (uppercased keys + cloned value Vecs) per DTSTART/DTEND/RECURRENCE-ID on **every CalDAV PUT / iCal import**, though all 5 production call sites only read `.get("VALUE")` (all-day detect) or discarded the map. Now `prop_value_and_is_date` scans `prop.params` directly for a case-insensitive `VALUE=DATE`. | per timed event | **6 → 2 allocs/op · 4.15× wall** (168.8 → 40.7 ns) |
+| **A2** | `UserDto::from(User)` took the `User` **by value** yet cloned every field through its accessors — including `image` (a data URI up to **512 KiB**) and `ui_preferences` (a full `serde_json::Value` tree) — on **every `/api/auth/me`** and admin user listing. Now `User::into_parts()` moves the owned fields (the treatment File/Folder/Contact already had). | 48 KiB avatar user | **27 → 14 allocs/op · 2.14× wall** (image memcpy + JSON deep-clone gone) |
+| **A3** | `ContactService::parse_vcard` collected `vcard_data.lines()` into a `Vec` it only iterated, and ran `line.to_ascii_uppercase()` — a full per-line `String` copy — per EMAIL/TEL/ADR line just to `.contains` a `TYPE=` token, on **every CardDAV PUT / vCard import**. Now iterates `lines()` directly and matches with the allocation-free `common::text::ascii_ci_contains` (the CalDAV parse path already used this shape). | 2 email / 1 tel / 1 adr | **8 → 1 allocs/op · 1.67× wall** (444.8 → 266.1 ns) |
+| **A4** | `CalendarDto::from` / `AddressBookDto::from` consumed the entity yet cloned `name`/`description`/`color` and (calendars) the whole `custom_properties` `HashMap<String,String>`, on **every CalDAV/CardDAV discovery listing**. Now `Calendar`/`AddressBook` grow `into_parts()` and move them. | calendar + 2 props | **18 → 10 allocs/op · 1.78× wall** |
+| **I1** | The file-listing repositories map rows with `.collect::<Result<Vec<T>, E>>()`, whose `Result`-shunt reports `size_hint().0 == 0` — so the `Vec` grows **from capacity 0** with ~⌈log₂N⌉ reallocations, memcpy-ing the accumulated `File`-sized rows each grow. Now `Vec::with_capacity(rows.len())` + push with `?` (the pattern `list_media_files` already used). | 500-row listing | **8 → 1 allocs/op** (container reallocs 8 → 0) |
+| **I4** | `encrypted_blob_backend::plaintext_stream` `.collect()`ed every emit-slice into a `Vec` before `stream::iter` — an eager container of ⌈len/64 KiB⌉ entries per **encrypted-blob read**. Now hands the lazy `map` iterator to `stream::iter` directly (same slice sequence). | 4 MiB → 64 slices | **2 → 1 allocs/op · 42.85× wall** (1732.8 → 40.4 ns) |
+| **C1** | NC `write_etag_element` built a `"…"`-quoted `String` then wrote it auto-escaped — `quick_xml` escapes the `"` → `&quot;`, re-allocating an owned `Cow`. Called **per file AND per folder row** of the NC streaming PROPFIND (the hottest DAV emit path), plus every favorites/search REPORT row and trashed item. Now emits the two quotes as **borrowed pre-escaped** `&quot;` text events around the escaped body. | per PROPFIND row | **3 → 0 allocs/op · 1.71× wall** (137.9 → 80.5 ns) |
+| **C3** | The NC favorites REPORT (`oc:filter-files`) hydrated `files`/`folders` by `file_map.get(&id).clone()` — cloning the **whole** `FileDto`/`FolderDto` out of maps that are dropped at fn end. Now `map.remove(&id)` moves them (item ids are unique per user; favorites order preserved — the round-19 M4 move-not-clone pattern applied to a path it missed). | 20 favorites | **302 → 162 allocs/op · 1.35× wall** (~7 allocs/favorite) |
+
+> Allocs/op is the deterministic primary gate (identical run to run). Wall
+> figures are single-shot and noise-bounded. Every section carries a
+> byte/-value equivalence gate; the shipped source now matches each AFTER arm.
+
+## [A1] CalendarEvent iCal parse — drop the per-property parameter HashMap
+
+`from_ical` and `update_ical_data` parse a VEVENT once, then read DTSTART, DTEND
+and RECURRENCE-ID via `prop_with_params`, which built a full
+`HashMap<String, Vec<String>>` per property:
+
+```rust
+let mut params: HashMap<String, Vec<String>> = HashMap::new();
+if let Some(param_list) = &prop.params {
+    for (name, values) in param_list {
+        params.insert(name.to_ascii_uppercase(), values.clone());   // upper key + value clone
+    }
+}
+Some((trimmed.to_string(), params))
+```
+
+Every production caller only ever asked the map one question — *does it carry
+`VALUE=DATE`?* (the all-day / date-only marker) — and the two DTEND sites
+discarded the map outright (`_dtend_params`, `_params`). The new
+`prop_value_and_is_date` answers exactly that, scanning `prop.params` directly:
+
+```rust
+let is_date = prop.params.as_ref()
+    .and_then(|list| list.iter().rev().find(|(n, _)| n.eq_ignore_ascii_case("VALUE")))
+    .map(|(_, vs)| vs.iter().any(|v| v.eq_ignore_ascii_case("DATE")))
+    .unwrap_or(false);
+```
+
+`.rev().find(...)` reproduces the old map's last-insert-wins semantics for a
+(pathological) duplicate-`VALUE` property, so the flag is byte-identical; DTEND
+now uses the plain `prop_value`. `prop_with_params` is retained behind
+`#[cfg(test)]` for its existing test wrapper. On a timed event (DTSTART+DTEND,
+each with a `TZID`): **6 → 2 allocs/op, 4.15× wall** — the 2 remaining are the
+DTSTART/DTEND value strings the callers need owned.
+
+## [A2] UserDto::from — move the 512 KiB image + JSON, don't clone
+
+`UserDto::from` consumes an owned `User` yet cloned every field through the
+borrowing accessors. Two of them are large: `image` is "a data URI of up to
+512 KiB" (the entity's own comment) and `ui_preferences` is a
+`serde_json::Value` tree — both deep-cloned on **every `/api/auth/me`** (session
+bootstrap on every app load, and after each profile edit) and once per user in
+admin listings. `User` was the one core entity without `into_parts`; adding it
+(exhaustive-destructure, compiler-checked) lets the conversion move:
+
+```rust
+let role = format!("{}", user.role());
+let can_edit_image = !user.is_oidc_user();   // derived flags read before the move
+let p = user.into_parts();
+… image: p.image, ui_preferences: p.ui_preferences,
+  auth_provider: p.oidc_provider.unwrap_or_else(|| "local".to_string()), …
+```
+
+**27 → 14 allocs/op, 2.14× wall** — the `image` memcpy + `String` alloc, the
+`ui_preferences` deep-clone, and 5 small field clones are gone; the OIDC-user
+`auth_provider` also stops re-allocating (moves the provider `String`). The DTO
+is byte-identical.
+
+## [A3] parse_vcard — allocation-free `TYPE=` routing
+
+`parse_vcard` (every CardDAV PUT / bulk import) collected the body into
+`Vec<&str>` it only iterated, and per EMAIL/TEL/ADR line ran
+`line.to_ascii_uppercase()` — a whole-line copy — purely to `.contains("TYPE=…")`.
+This is the exact allocation the CalDAV parse path already killed with
+`starts_with_ci`/`find_ci`; `ascii_ci_contains` was promoted from
+`search_service` to the shared `common::text` module (DRY) and both callers now
+use it. **8 → 1 allocs/op, 1.67× wall** for a 2-email/1-phone/1-address card
+(the remaining alloc is the result Vec both arms build).
+
+## [A4] Calendar/AddressBook DTO — finish the into_parts family
+
+`CalendarDto::from` / `AddressBookDto::from` consumed the entity but cloned
+`name`/`description`/`color` and — for calendars — the whole
+`custom_properties` `HashMap<String,String>`, on every CalDAV/CardDAV discovery
+listing (DAVx5/Apple poll these repeatedly). Both entities grew `into_parts()`
+and the conversions move. **18 → 10 allocs/op, 1.78× wall** (the HashMap clone +
+3 string clones gone; the two `Uuid::to_string`s remain).
+
+## [I1] Result-collect never pre-sizes — the file-listing repositories
+
+`collect::<Result<Vec<T>, E>>()` collects through a `Result` shunt whose
+`size_hint().0` is `0` (any element may short-circuit the collect), so `Vec`'s
+`extend` reserves nothing and the container grows **from capacity 0** — ~⌈log₂N⌉
+reallocations, each memcpy-ing the accumulated `File` rows (≈120 B apiece). The
+bench isolates the container behaviour on 500 File-sized rows: **8 container
+reallocations → 0** (one `with_capacity` alloc). Applied to the four
+`file_blob_read_repository` listing/paging/subtree/by-ids mappers (the hottest
+paths — folder browse, PROPFIND, search, favorites/ACL hydration); the fix is
+the loop `list_media_files` already used:
+
+```rust
+let mut files = Vec::with_capacity(rows.len());
+for (id, name, …) in rows {
+    files.push(Self::row_to_file(id, name, …).map_err(…)?);
+}
+Ok(files)
+```
+
+`?` short-circuits on the first row error exactly as the `Result`-collect did —
+byte-identical behaviour and error message.
+
+## [I4] plaintext_stream — lazy emit iterator
+
+The encrypted backend's `plaintext_stream` `.collect()`ed a
+`Vec<Result<Bytes>>` of ⌈len/64 KiB⌉ zero-copy slices before handing it to
+`stream::iter` — an eager container built per encrypted read (a legacy
+whole-file blob → thousands of entries). The `move` closure owns the refcounted
+`Bytes`, so the `map` iterator is `Send + 'static` and can be streamed lazily.
+**2 → 1 allocs/op, 42.85× wall** (the eager Vec build + fill is gone; each slice
+is now produced on demand as the consumer polls, also cutting peak RAM).
+
+## [C1] NC write_etag_element — borrowed pre-escaped quotes
+
+`write_etag_element` is called per file **and** per folder row of the NC
+streaming PROPFIND — the single most-travelled DAV emit path — plus every
+favorites/search REPORT row and trashed item. It built a `"…"`-quoted `String`
+and wrote it auto-escaped; `quick_xml` escapes a literal `"` to `&quot;`, so the
+whole-string escape re-allocated an owned `Cow` (3 allocs total, measured). The
+new form emits the two quotes as **borrowed** pre-escaped `&quot;` text events
+around the escaped etag body:
+
+```rust
+xml.write_event(Event::Text(BytesText::from_escaped("&quot;")))?;   // borrowed, 0 alloc
+xml.write_event(Event::Text(BytesText::new(etag)))?;                // escaped body
+xml.write_event(Event::Text(BytesText::from_escaped("&quot;")))?;
+```
+
+The output is byte-identical to escaping `"{etag}"` as one string — the
+equivalence gate asserts it, including an etag with `&`/`<`/`"`. **3 → 0
+allocs/op, 1.71× wall.**
+
+## [C3] favorites REPORT — move the DTO out of the map
+
+`oc:filter-files` builds `file_map`/`folder_map` two lines before the hydrate
+loop, uses them only to populate `files`/`folders` in favorites order, and drops
+them at fn end — yet cloned the **whole** DTO out with `.get().clone()`. Since
+`favorites.item_id` is unique per user, `.remove()` moves the DTO out with no
+risk of dropping a needed duplicate and preserves order (the round-19 M4
+pattern). **302 → 162 allocs/op** for a 20-favorite page — ~7 owned-String
+allocs saved per favorite.
+
+## Not shipped — deferred to a later round
+
+Surfaced during the Round-20 audit, measured or confirmed, but held back to keep
+this round's diff focused / because they need Postgres or a dependency decision:
+
+- **NC `oc:id` per-row `String` (`format_oc_id`):** `format!("{:08}{instance}")`
+  allocates one `String` per PROPFIND/REPORT/trashbin row. A `format_oc_id_into(&mut
+  String, …)` buffer reused across the page (mirroring the M6 href buffer already
+  threaded through those loops) makes it **1 → 0 allocs/row** — but it's a
+  multi-signature change through `write_file_response`/`write_folder_response`,
+  deferred to keep this round per-item-local.
+- **NC trashbin PROPFIND per-item href + folder content_type:** the trashbin loop
+  still `format!`s each `href` and `"httpd/unix-directory".to_string()`s the folder
+  content-type per row — the M6 href-buffer + `Cow<'static, str>` fix that reached
+  the files/folders loops but not trashbin.
+- **I1 sibling listing paths:** the same `collect::<Result<Vec>>()` /
+  `Vec::new()`+push shape lives in the CardDAV (`contact_pg_repository`,
+  `contact_group_pg_repository`) and CalDAV (`calendar_event_pg_repository`,
+  `calendar_pg_repository`) row mappers. Mechanically identical to the file-side
+  fix shipped here; extend next (bulk address-book / calendar sync builds
+  thousands of rows).
+- **Contact JSONB columns decode through a throwaway `serde_json::Value`
+  (`contact_pg_repository::row_to_contact`, needs Postgres to bench):**
+  `row.get::<JsonValue>` builds a full `Value` tree per email/phone/address column
+  before `from_value` walks and drops it. `sqlx::types::Json<Vec<Dto>>` runs
+  `from_slice` on the raw JSONB — same Vec, no intermediate tree, tens of allocs
+  saved per contact.
+- **Dedup `settle_batch` clones chunk-hash `String`s for the SQL array bind
+  (`dedup_service`, needs Postgres):** `batch.iter().map(|(h, _)| h.clone())` deep-
+  clones each 64-char hash purely to `.bind()`, though `batch` outlives the query;
+  `&[&str]` encodes to `text[]` identically — up to 32 fewer allocs per new-content
+  batch (~4000 over a 1 GB upload).
+- **Fast hasher for internal maps (cross-cutting, needs a dependency decision):**
+  every `HashMap`/`HashSet` in the tree uses std SipHash. Trusted-key,
+  built-per-request maps would benefit from a faster `BuildHasher` — the hottest
+  are the NC PROPFIND per-row `favorite_ids.contains(&file.id)` /
+  `nc_id_of` lookups, and the delta-upload `distinct_hashes` /
+  `authorize_chunk_download` sets over up to ~40 000 client-supplied 64-char
+  hashes. Two caveats keep it out of this round: it changes **no allocations** (so
+  it can't use the alloc gate — only the noisy wall metric), and it needs a
+  `Cargo.toml` dependency; the delta sets are **attacker-controlled**, so the
+  replacement must stay DoS-resistant (`ahash`/`foldhash` with a random seed, not
+  `FxHash`). Worth a dedicated, wall-gated evaluation.
+
+## Environment / methodology
+
+- `cargo run --release --features bench --example bench_round20_micro` —
+  counting global allocator, no Postgres. Tunables (env): `BENCH_ITERS` (200000),
+  `I1_ROWS` (500).
+- Each section is BEFORE (verbatim replica of the shipped-before shape) vs AFTER
+  (verbatim replica of the shipped-after shape, which the source is then made to
+  match), with a byte/-value equivalence gate; the shipped source now matches
+  each AFTER arm.
+- Roll-back rule encoded per section: the harness `std::process::exit(1)`s with
+  `GATE FAIL … rollback` if an AFTER arm fails to reduce allocations. All eight
+  sections pass.

+# Round 21 — CalDAV/CardDAV row-mapper pre-size, dedup hash-bind & digest-key dedup, CardDAV etag & BDAY emit, NC trashbin content-type
+
+Benchmark-gated, same rule as ROUND2–20: every change ships with a BEFORE/AFTER
+benchmark and a byte/-value equivalence gate; an AFTER that doesn't beat its
+BEFORE is rolled back (never applied). The roll-back rule is encoded directly in
+the harness — a `GATE FAIL … rollback` non-zero exit if an AFTER arm fails to
+reduce allocations — so a regression fails CI rather than shipping.
+
+This round drains the sibling seams the earlier passes explicitly deferred. The
+file-listing repositories got their result-`Vec` pre-sizing in ROUND20 §I1, but
+the **CalDAV/CardDAV row mappers** (bulk address-book / calendar sync builds
+thousands of rows) were left growing from capacity 0. The **streaming ingest**
+loop got its `[u8; 32]`-digest dedup key in ROUND17 §D2, but its **delta-upload
+sibling** `store_loose_chunks` kept a `HashSet<String>` and a double hex clone
+per frame. The **NextCloud** etag emitter got the borrowed-pre-escaped-quote
+treatment in ROUND20 §C1, but the **CardDAV** emitter still built a quoted
+`String`. And two dedup/DAV emit micro-cuts the earlier rounds named but held
+back: the `settle_batch` clone-to-bind and the `BDAY` strftime stamp.
+
+Reproduce:
+
+```
+cargo run --release --features bench --example bench_round21_micro
+```
+
+All arms are **no-Postgres** (release-profile counting-allocator example).
+
+## Summary
+
+| # | change | key metric | before → after |
+|--:|---|---|---|
+| **R1** | The CalDAV/CardDAV row-mapping repositories (`calendar_event_pg_repository`, `calendar_pg_repository`, `contact_pg_repository`, `contact_group_pg_repository`) built their result `Vec` with `let mut v = Vec::new(); for row in rows { v.push(map(row)?) }` — growing from capacity 0 (~⌈log₂N⌉ reallocations, each memcpy-ing the accumulated rows) on **every CalDAV/CardDAV listing, multiget & bulk sync**. Now `Vec::with_capacity(rows.len())` (the ROUND20 §I1 file-side pattern extended to the 16 calendar/contact sites it deferred). Plus one `HashMap` (`get_calendar_properties`). | 200-row listing | **7 → 1 allocs/op** (6 fewer) |
+| **R2** | `DedupService::settle_batch` cloned every 64-char chunk hash into a `Vec<String>` purely to `.bind()` it to the pin `UPDATE … WHERE hash = ANY($1)`, on **every settle batch of every upload** (~128 batches for a 1 GB fully-unique upload). Now binds a borrowed `Vec<&str>` — sqlx encodes `&[&str]` to `text[]` identically (`favorites_pg_repository.rs:271` already does this). | 32-chunk batch | **33 → 1 allocs/op · 39.4× wall** |
+| **R3** | `DedupService::store_loose_chunks` — the delta-upload sibling of the ROUND17 §D2 ingest loop — kept an intra-request dedup `HashSet<String>` and cloned the hex hash **twice per frame** (into `received` and into the set; the set clone dropped on the spot for a duplicate). Now keys the set on the raw `[u8; 32]` BLAKE3 digest (`Copy`, no per-distinct-chunk heap key) and moves the hex into `received` on a duplicate. Runs **per frame** on delta/sync uploads (thousands of frames for a large changed file). | 128 frames, 50% dup | **401 → 209 allocs/op (192 fewer) · 1.50× wall** |
+| **R4** | `carddav_adapter::write_contact_response` built a `"…"`-quoted `String` for `getetag` then wrote it auto-escaped — `quick_xml` escapes the `"` → `&quot;`, re-allocating an owned `Cow` — on **every contact of every CardDAV multiget/PROPFIND** (plus the per-address-book collection etag). Now emits the two quotes as borrowed pre-escaped `&quot;` text events (the ROUND20 §C1 NextCloud pattern, via a shared `write_quoted_etag` helper covering all 4 CardDAV etag sites). | per-contact row | **3 → 0 allocs/op · 2.11× wall** |
+| **R5** | `contact_to_vcard` stamped `BDAY` via `write!(…, "{}", bday.format("%Y-%m-%d"))`, running chrono's strftime interpreter per **contact-with-birthday**. Now renders the fixed `YYYY-MM-DD` on the stack via the new `fmt::compact_date` (the date-only companion to the §V2 `REV` renderer), chrono fallback for out-of-range years. | per bday contact | **2 → 0 allocs/op · 10.51× wall** |
+| **R6** | The NextCloud trashbin PROPFIND row set `d:getcontenttype` for a folder to `"httpd/unix-directory".to_string()` — a heap `String` for a static constant, **per trashed folder row**. Now `Cow::Borrowed` (the ROUND16 §M1 `Cow<'static, str>` pattern); only the file branch (mime_guess) still owns its String. | per folder row | **1 → 0 allocs/op · 5.76× wall** |
+
+> Allocs/op is the deterministic primary gate (identical run to run). Wall
+> figures are single-shot and noise-bounded. Every section carries a
+> byte/-value equivalence gate; the shipped source now matches each AFTER arm.
+
+## [R1] CalDAV/CardDAV row-mapper container pre-size
+
+`collect::<Result<Vec>>()` was ROUND20 §I1's target on the file side; the
+CalDAV/CardDAV repos use the equivalent `Vec::new()` + `for row in rows { … }`
+shape, which grows the container the same way — from capacity 0, reserving
+nothing, so `push` reallocates ~⌈log₂N⌉ times and memcpy-s the accumulated
+(Contact/Event-sized) rows on each grow. `rows` is a materialized `fetch_all`
+result, so `rows.len()` is exact:
+
+```rust
+let mut events = Vec::with_capacity(rows.len());
+for row in rows {
+    events.push(Self::row_to_event(row)?);   // ? short-circuits identically
+}
+```
+
+Applied to the 16 listing/multiget/paginated mappers across the four repos
+(`calendar_event` ×6, `calendar` ×2 + the `get_calendar_properties` HashMap,
+`contact` ×6, `contact_group` ×1). The `subject_group` and
+`nextcloud_object_id` sibling mappers already pre-sized (`with_capacity(rows.len())`),
+so they were left untouched. Byte-identical output; on a 200-row listing the
+container allocations drop from **7 → 1** (the growth-from-0 reallocations
+replaced by a single exact reserve).
+
+## [R2] settle_batch — bind borrowed `&str`, don't clone
+
+`settle_batch` runs once per flushed chunk batch of every upload. It built an
+owned `Vec<String>` of the batch's 64-char hashes only to `.bind()` it:
+
+```rust
+let hashes: Vec<String> = batch.iter().map(|(h, _)| h.clone()).collect();  // N heap Strings
+// … .bind(&hashes) … WHERE hash = ANY($1) …
+```
+
+`batch` outlives the query (it is consumed two statements later), so the hashes
+can be borrowed. sqlx encodes `&[&str]` to a PostgreSQL `text[]` identically to
+the owned `Vec<String>` (the pattern `favorites_pg_repository.rs:271` already
+uses, with the comment *"sqlx binds `&[&str]` as text[], so no per-id String is
+needed"*). The borrow is scoped in a block so it ends before `batch` is moved:
+
+```rust
+let pinned: HashSet<String> = {
+    let hashes: Vec<&str> = batch.iter().map(|(h, _)| h.as_str()).collect();
+    sqlx::query_scalar::<_, String>("UPDATE … WHERE hash = ANY($1) RETURNING hash")
+        .bind(&hashes).fetch_all(pool.as_ref()).await?.into_iter().collect()
+};
+```
+
+Up to `FLUSH_MAX_CHUNKS` (=32) 64-byte `String` allocations removed per batch —
+~4000 over a 1 GB fully-unique upload — for one pointer-only `Vec`.
+
+## [R3] store_loose_chunks — digest-keyed dedup set + move-on-duplicate
+
+The delta-upload ingest (`store_loose_chunks`) is the sibling ROUND17 §D2 didn't
+reach. Per frame it allocated the 64-char hex hash and then cloned it twice:
+
+```rust
+let hash = blake3::hash(&data).to_hex().to_string();
+received.push((hash.clone(), data.len() as u64));   // clone 1 (always)
+if seen.insert(hash.clone()) {                       // clone 2 (always; HashSet<String>)
+    new_rows.push((hash, len));
+}
+```
+
+`seen` is the **intra-request** dedup set (has this exact chunk already appeared
+in *this* delta stream? — re-chunked near-duplicates, zero-padded regions). Keyed
+on the raw 32-byte digest it needs no per-distinct-chunk `String`, and a
+duplicate frame **moves** the hex into `received` instead of cloning:
+
+```rust
+let digest = blake3::hash(&data);
+let hash = digest.to_hex().to_string();
+let len = data.len();
+if seen.insert(*digest.as_bytes()) {         // HashSet<[u8; 32]>, Copy key
+    self.backend.put_blob_from_bytes_unsynced(&hash, data).await?;
+    received.push((hash.clone(), len as u64));
+    new_rows.push((hash, len as i64));
+} else {
+    received.push((hash, len as u64));       // move, no clone
+}
+```
+
+hex ↔ digest is bijective, so membership and the `received`/`new_rows`
+sequences are identical. On a 128-frame stream with 50 % intra-request dups the
+per-frame hash clones drop from 3 to ~1.5.
+
+## [R4] CardDAV getetag — borrowed pre-escaped quotes
+
+`write_contact_response` (per contact of every CardDAV multiget/PROPFIND) built
+a `"…"`-quoted `String` and wrote it auto-escaped; `quick_xml` escapes the `"`
+to `&quot;`, so the whole-string escape re-allocated an owned `Cow`. The new
+shared `write_quoted_etag` helper emits the two quotes as **borrowed**
+pre-escaped `&quot;` text events around the escaped etag body — byte-identical
+(the equivalence gate asserts it, including an etag with `&`/`<`/`"`), 0
+allocs/contact. Applied to all four CardDAV etag sites (2 per-contact + 2
+per-address-book collection), mirroring the NextCloud ROUND20 §C1 fix.
+
+## [R5] BDAY — stack-rendered `%Y-%m-%d`
+
+`contact_to_vcard` already stack-renders `REV` (ROUND19 §V2); `BDAY` still went
+through chrono's strftime interpreter (`bday.format("%Y-%m-%d")`). The new
+`fmt::compact_date(buf, year, month, day)` renders the fixed 10-byte
+`YYYY-MM-DD` with the same `push4`/`push2` LUT the other `fmt` helpers use, and
+returns `None` outside the 4-digit-year range (where chrono widens/sign-prefixes
+`%Y`) so the caller keeps the chrono path as fallback. Byte-identical for every
+representable birthday.
+
+## [R6] NC trashbin folder content-type — borrowed constant
+
+The trashbin PROPFIND folder branch `to_string()`-ed the static
+`"httpd/unix-directory"` per row. `Cow::Borrowed` for the folder constant (the
+file branch still owns its mime_guess String) drops that allocation per trashed
+folder row — the ROUND16 §M1 `Cow<'static, str>` pattern the trashbin loop
+missed.
+
+## Not shipped — deferred to a later round
+
+Surfaced by the Round-21 audit (three parallel sub-audits across the HTTP,
+storage/dedup and application/parse layers), verified against current source,
+but held back — each needs a signature/API decision, a Postgres fixture, or a
+gate the deterministic alloc-counter can't provide:
+
+- **Hot GET handlers clone the whole request `HeaderMap`** (`file_handler`
+  list/download/thumbnail, `photos_handler`, NC `preview`/`avatar`): axum's
+  `HeaderMap` extractor does `parts.headers.clone()` (~2 allocs) purely to read
+  1–3 headers — the exact cost `middleware/auth.rs` already eliminated (ROUND14
+  §A4) but never propagated to the handlers. The fix takes `req: Request` last
+  and reads `req.headers()` by borrow; it's a **multi-handler signature refactor**
+  (each `_impl` + its wrapper + the route registration) that wants its own
+  validated pass, same class as the ROUND19/20 multi-signature deferrals.
+- **`Query<HashMap<String,String>>` on the hot list/download paths** builds a
+  `HashMap` + key `String` per request to read one param; a typed
+  `Query<ListFilesQuery>` struct drops both (serde ignores unknown params). Same
+  signature-surface reason as above; pairs naturally with the HeaderMap pass.
+- **Native WebDAV PROPFIND re-extracts the URI path** (`webdav_handler.rs:507`):
+  `extract_webdav_path(req.uri())` re-runs a percent-decode + `String` alloc that
+  the `path` parameter already holds at that point (the `:503` comment about the
+  prefix is stale). One decode + alloc per PROPFIND — but removing it needs a
+  careful href-equivalence proof across the chroot/scope resolution, so it wants
+  a dedicated correctness check, not a perf banner.
+- **`music_service` public-playlist merge is O(owned·public)** (`Vec::any()` per
+  public item): a `HashSet` makes it O(owned+public). Because `PlaylistDto.id` is
+  a `String`, the set must own the ids (clone) — so the change trades N String
+  comparisons for N String clones: a **wall win that ADDS allocations**, which
+  the deterministic alloc gate can't score. Wants a wall-gated evaluation on the
+  opt-in `include_public` path.
+- **WebDAV dead-props filter is O(N·D·R)** (`webdav_adapter.rs:616/705`): the
+  loop-invariant requested-props list is re-scanned per dead prop per resource;
+  a per-PROPFIND `HashSet<&QualifiedName>` makes it O(N·D). Only bites accounts
+  that accumulate client-set custom props (macOS Finder) over large listings —
+  and, like music_service, the HashSet build trades compares for an alloc, so
+  it's wall-gated. Queued with a synthetic-dead-props bench.
+- **`verify_integrity` Phase 1 probes manifest chunks serially** while Phase 2
+  is `buffer_unordered(16)` — on a remote backend that's O(total_chunks) serial
+  HEADs. Background/admin path; needs a remote-backend fixture to show the win.
+- **`subject_group_service::remove_member` runs the same recursive-CTE
+  `list_transitive_users(child_id)` twice** for a nested group removal (the
+  intervening edge delete can't change the child's descendants). One DB
+  round-trip halved; low frequency (admin), needs Postgres.
+- **`store_loose_chunks` final registration + `run_rollback` clone hashes to
+  bind** (`dedup_service.rs:887/212`), and the **`contact_pg` JSONB columns
+  decode through a throwaway `serde_json::Value`** — the R2/ROUND20 patterns
+  applied to once-per-upload / per-contact-read sites; both need Postgres to
+  bench end-to-end.
+- **`GzipCompressionService::{compress,decompress}_data` copy the whole buffer
+  via `.to_vec()`** before `spawn_blocking` — forced by the `&[u8]` port
+  signature; a `Bytes`-taking port lets an owning caller move. Port API change,
+  gated (text > 50 KB), low heat.
+- **Fast hasher for trusted-key internal maps** (ROUND20 flag stands): needs a
+  `Cargo.toml` dependency decision and must stay DoS-resistant for the
+  attacker-controlled delta-hash sets — worth a dedicated, wall-gated pass.
+
+## Environment / methodology
+
+- `cargo run --release --features bench --example bench_round21_micro` —
+  counting global allocator, no Postgres. Tunables (env): `BENCH_ITERS` (200000),
+  `R1_ROWS` (200), `R3_FRAMES` (128).
+- Each section is BEFORE (verbatim replica of the shipped-before shape) vs AFTER
+  (verbatim replica of the shipped-after shape, which the source is then made to

+# Round 22 — hot-GET HeaderMap borrow, native-WebDAV & CalDAV etag borrowed quotes, FileDto content_hash move, CalendarEvent stamp, ShareItemType case-fold
+
+Benchmark-gated, same rule as ROUND2–21: every change ships with a BEFORE/AFTER
+benchmark and a byte/-value equivalence gate; an AFTER that doesn't beat its
+BEFORE is rolled back (never applied). The roll-back rule is encoded directly in
+the harness — a `GATE FAIL … rollback` non-zero exit if an AFTER arm fails to
+reduce allocations — so a regression fails CI rather than shipping.
+
+This round drains the two biggest items the ROUND21 audit explicitly deferred —
+the hot-GET-handler `HeaderMap` extractor clone and the two DAV etag emitters the
+borrowed-pre-escaped-quote sweep never reached (native WebDAV + CalDAV) — plus
+the `FileDto::from` `content_hash` clone the ROUND19/20 move-not-clone sweep
+missed (it is computed *before* `into_parts()`), and two low-heat strftime /
+case-fold cuts.
+
+Reproduce:
+
+```
+cargo run --release --features bench --example bench_round22_micro
+```
+
+All arms are **no-Postgres** (release-profile counting-allocator example).
+
+## Summary
+
+| # | change | key metric | before → after |
+|--:|---|---|---|
+| **H1** | The hot GET handlers (`get_thumbnail`, `download_file`, `list_files_query`, `list_photos`, NextCloud `preview`, public-share `download`/`access`) took axum's `HeaderMap` extractor, whose `FromRequestParts` impl does `parts.headers.clone()` — an owned clone of the **whole** request header table — purely to read 1–3 headers (`If-None-Match` / `Accept` / `Range` / unlock cookie). Now they take `req: Request` last and read `req.headers()` by borrow (the ROUND14 §A4 middleware pattern, finally propagated to the handlers). The 3 wrapper/`_impl` file handlers pass `req.headers()` into an `_impl` that now takes `&HeaderMap` (`+ use<>` on the return so the 2024-edition `impl Trait` capture doesn't tie the owned `Response` to the borrow). | realistic 13-header req | **2 → 0 allocs/op · 9.95× wall** |
+| **W1** | `webdav_adapter::write_etag_quoted` — the etag emitter for **every** native `/webdav/` PROPFIND row (per file AND per folder, up to `PROPFIND_BATCH_SIZE`=500/page — the most-travelled DAV path) — built a sized `"{etag}"` `String` then wrote it auto-escaped; `quick_xml` escapes the `"` → `&quot;`, re-allocating an owned `Cow`. Now emits the two quotes as borrowed pre-escaped `&quot;` text events around the escaped body (the ROUND20 §C1 / ROUND21 §R4 pattern the native adapter never got). Byte-identical for any etag. | per PROPFIND row | **3 → 0 allocs/op · 1.59× wall** |
+| **C1** | The CalDAV `getetag` emit — per event of every calendar-query/multiget/sync REPORT + depth-1 collection PROPFIND (the DAVx5/Apple/Thunderbird sync path), and per calendar of the home-set PROPFIND — still escaped a `"…"` value: the event sites paid the escape `Cow` over the ROUND14 reused buffer (1 alloc/event); the two calendar sites `format!`-ed as well (2 allocs). All **five** sites now route through a new `write_quoted_etag` helper (the CardDAV twin), and the now-dead `etag: &mut String` buffer threaded through `write_event_response`/`write_event_standard_props`/`write_event_requested_props` + the two page buffers are dropped. | per event row | **2 → 0 allocs/op · 1.63× wall** |
+| **D1** | `FileDto::from` computed `content_hash = file.content_hash().to_string()` (a clone of `blob_hash`) and then `into_parts()` **moved** that same `blob_hash` into `parts.blob_hash`, which was dropped unused in the `Self { … }` ctor. The ROUND19/20 move-not-clone sweep fixed id/name/path/folder_id but missed this one because the etag/hash are read *before* `into_parts()`. Now `content_hash: parts.blob_hash` reuses the moved `String`; `etag` still computes first from the live entity. Runs **per file row on every listing** (folder browse, streaming PROPFIND, search/favorites/recent hydration). | per file row | **1 → 0 allocs/op · 2.91× wall** |
+| **E1** | `CalendarEvent::update_time_range` / `update_all_day` stamped **timed** DTSTART/DTEND via `format!("{}", t.format("%Y%m%dT%H%M%SZ"))` — chrono's strftime `DelayedFormat` interpreter. Now stack-renders via the shipped `fmt::compact_ical_utc` and passes the `&str` straight to `update_ical_property`, with the chrono `format!` kept as the out-of-range fallback and the all-day `%Y%m%d` form untouched. Per event-edit PUT. | per timed stamp | **4 → 0 allocs/op · 14.49× wall** |
+| **S1** | `ShareItemType::try_from` matched `s.to_lowercase().as_str()` — a throwaway Unicode-lowercased `String` — against the two ASCII literals `"file"`/`"folder"`. Now `s.eq_ignore_ascii_case("file")` / `("folder")`: byte-identical acceptance for the ASCII targets, no allocation. | per parse | **1 → 0 allocs/op · 7.81× wall** |
+
+> Allocs/op is the deterministic primary gate (identical run to run). Wall
+> figures are single-shot and noise-bounded. Every section carries a
+> byte/-value equivalence gate; the shipped source now matches each AFTER arm.
+
+## [H1] Hot GET handler `HeaderMap` extractor → `Request` + borrow
+
+axum 0.8's `impl FromRequestParts for HeaderMap` is literally
+`Ok(parts.headers.clone())` — cloning the whole request header table (its
+`entries` + `indices` backing vectors; the counting allocator measures exactly
+2 allocs on a realistic 13-header browser request). The handlers below read only
+1–3 headers out of it, so the clone is pure waste — the exact cost
+`middleware/auth.rs` removed in ROUND14 §A4 (`request.headers().get(…)` by
+borrow) but which was never propagated to the handlers.
+
+The fix takes `req: Request` as the **last** extractor (all the others —
+`State`, `AuthUser`, `Path`, `Query` — are `FromRequestParts`, so they coexist
+with a single trailing `FromRequest`), and reads `req.headers()` by borrow:
+
+- **Standalone handlers** (`list_photos`, NC `preview`, share `download`/`access`):
+  swap `headers: HeaderMap` for `req: Request` and read `req.headers().get(…)`
+  at the (single) use site.
+- **Wrapper/`_impl` handlers** (`get_thumbnail`, `download_file`,
+  `list_files_query`): the wrapper takes `req: Request` and passes
+  `req.headers()` into an `_impl` whose param becomes `headers: &HeaderMap`. The
+  `_impl` return type gets `+ use<>` so the 2024-edition `impl Trait` lifetime
+  capture doesn't tie the (owned) `Response` output to the header borrow — the
+  future still borrows the headers during its inline `.await`, but the response
+  it yields captures nothing.
+
+Byte-identical: every call site reads the same header by `.get()`. The
+`openapi_spec_is_valid_and_has_expected_structure` test confirms the
+utoipa-annotated handlers still emit a valid spec after the signature change.
+
+NextCloud `avatar` (dual caller `handle_dav_avatar` → `handle_avatar` + dual
+route) and the share-management handlers (`create`/`update`/… take a `Json`
+body, so no second `Request` extractor is possible) were left for a dedicated
+pass — see *Not shipped*.
+
+## [W1] Native WebDAV `getetag` — borrowed pre-escaped quotes
+
+`write_etag_quoted` is the single helper behind all four native PROPFIND etag
+sites (`webdav_adapter.rs:857/935/1004/1089` — file + folder, allprop + named).
+It built a `String::with_capacity(etag.len()+2)` `"{etag}"` and wrote it via
+`BytesText::new`, which escapes the `"` → `&quot;` and re-allocates an owned
+`Cow`. Now (the ROUND20 §C1 / ROUND21 §R4 shape):
+
+```rust
+xml_writer.write_event(Event::Text(BytesText::from_escaped("&quot;")))?; // borrowed
+xml_writer.write_event(Event::Text(BytesText::new(etag)))?;             // escaped body
+xml_writer.write_event(Event::Text(BytesText::from_escaped("&quot;")))?;
+```
+
+`escape` maps `"`→`&quot;` per char, so `&quot;{escape(etag)}&quot;` is
+byte-identical to escaping `"{etag}"` for **any** etag (the equivalence gate
+asserts it, including an etag carrying `&`/`<`/`"`). One helper body fixes all
+four call sites — 0 allocs/row on the hottest native-WebDAV path.
+
+## [C1] CalDAV `getetag` — shared `write_quoted_etag` helper (5 sites)
+
+The CalDAV adapter was the last DAV emitter still escaping a quoted etag value.
+A new file-local `write_quoted_etag` (identical to the shipped CardDAV twin)
+replaces the manual quote-and-escape at all five sites:
+
+- `write_event_standard_props` / `write_event_requested_props` /
+  `write_collection_event_page` — **per event bundle** (the reused ROUND14
+  buffer was already amortized, so the remaining cost was the escape `Cow`;
+  1 → 0 alloc/event).
+- `write_calendar_standard_props` / `write_calendar_requested_props` — **per
+  calendar**, which additionally `format!`-ed the value (2 → 0).
+
+The etag bodies are bare `Uuid`s (`anchor.id` / `calendar.id`), so
+`BytesText::new(id)` is itself a borrow (0 allocs). With the emit no longer
+needing a scratch `String`, the `etag: &mut String` buffer threaded through
+`write_event_response` → `write_event_standard_props` /
+`write_event_requested_props` and the two per-page `String::new()` buffers were
+removed. The 34 caldav-adapter unit tests (PROPFIND/REPORT output) pass
+unchanged.
+
+## [D1] `FileDto::from` — reuse the moved `blob_hash`, don't clone it
+
+The per-row DTO builder computed the ETag and the content hash from the live
+entity, then consumed it:
+
+```rust
+let etag = file.etag();
+let content_hash = file.content_hash().to_string();   // clone of self.blob_hash
+let parts = file.into_parts();                         // MOVES self.blob_hash → parts.blob_hash
+// … Self { …, content_hash, etag, … }                // parts.blob_hash dropped unused
+```
+
+`etag` genuinely must run against the live entity (it borrows `blob_hash` +
+`modified_at`), but `content_hash` is just the raw hash — and `into_parts()`
+already hands it over by ownership. Now `content_hash: parts.blob_hash` reuses
+that `String`; the getter clone (one 64-byte hex `String` per row) is gone. This
+is the file-side twin of the fields `FolderDto::from` already moves, on the
+single most-travelled API path. Byte-identical: `parts.blob_hash` **is** the
+`String` the getter cloned.
+
+## [E1] `CalendarEvent` timed DTSTART/DTEND — `compact_ical_utc` stack render
+
+The timed branches of `update_time_range` / `update_all_day` stamped
+`format!("{}", t.format("%Y%m%dT%H%M%SZ"))`, running chrono's strftime
+interpreter (4 allocs measured). `fmt::compact_ical_utc` already renders exactly
+`YYYYMMDDTHHMMSSZ` on the stack (the ROUND19 §V2 helper), and the property
+setter takes a `&str`, so the render is passed straight through with no owned
+`String`:
+
+```rust
+let start_str: &str = if self.all_day {
+    start_owned = format!("{}T000000Z", start_time.format("%Y%m%d")); &start_owned
+} else if let Some(s) = fmt::compact_ical_utc(&mut sbuf, start_time.timestamp()) {
+    s                                          // 0 allocs, the common case
+} else {
+    start_owned = format!("{}", start_time.format("%Y%m%dT%H%M%SZ")); &start_owned  // fallback
+};
+```
+
+The all-day `%Y%m%d` + literal-suffix form is unchanged (no existing
+no-separator helper covers it — see *Not shipped*). The 20 calendar_event unit
+tests (iCal round-trip, exception handling) pass unchanged.
+
+## [S1] `ShareItemType::try_from` — `eq_ignore_ascii_case`
+
+`match s.to_lowercase().as_str()` allocated a Unicode-lowercased `String` per
+call only to compare against `"file"`/`"folder"`. `eq_ignore_ascii_case` folds
+only ASCII A–Z — but the targets are pure ASCII, and any input whose
+`to_lowercase()` equals `"file"`/`"folder"` is by definition an ASCII case
+variant of it, so acceptance is byte-identical (the gate checks mixed-case +
+invalid inputs). 0 allocs.
+
+## Not shipped — deferred to a later round
+
+Surfaced by the Round-22 audit (three parallel sub-audits across the HTTP, DAV
+and application/parse layers), verified against current source, but held back —
+each needs a signature/API decision or a gate the deterministic alloc-counter
+can't provide:
+
+- **`list_files_query` `Query<HashMap<String,String>>` → typed `Query<…>`**: the
+  listing reads only `folder_id`, so a `struct ListFilesQuery { folder_id:
+  Option<String> }` drops the `HashMap` table + the `"folder_id"` key `String`
+  (~3 → 1 allocs). Byte-identical for the frontend's actual usage, but a
+  **malformed** `?folder_id=a&folder_id=b` diverges (HashMap last-wins vs serde
+  field-decode), so it wants its own byte-identity proof before shipping — the
+  H1 half of this handler is unimpeachable and shipped alone.
+- **NextCloud `avatar` HeaderMap clone**: `handle_avatar` has two callers
+  (`handle_dav_avatar` + a direct route), so the `Request` conversion is a
+  dual-signature change, not the clean leaf swap the other H1 handlers were.
+  Low frequency (avatars revalidate hourly).
+- **Share-management HeaderMap clones** (`create`/`update`/`verify`/… at
+  `share_handler.rs:583+`): these take a `Json` body (a `FromRequest` body
+  extractor), so a second `Request` extractor is impossible — they need a
+  different borrow strategy. Lower frequency than the public download/access
+  path shipped here.
+- **`update_all_day` / `update_time_range` all-day `%Y%m%d` stamp**: no
+  no-separator date helper exists (`compact_ical_utc` is date+time,
+  `compact_date` is `YYYY-MM-DD`); a `compact_date_basic` (`YYYYMMDD`) would
+  close the remaining 2 all-day sites. Low heat.
+- **`ContactService::generate_vcard` BDAY** (`contact_service.rs:342`) still uses
+  `birthday.format("%Y%m%d")` on the contact write path — same missing
+  `%Y%m%d` helper as above; the per-contact *read* twin was already fixed
+  (ROUND21 §R5). Low heat.
+- **`extract_webdav_path(req.uri())`** (`webdav_handler.rs:507`): a per-PROPFIND
+  percent-decode + `String`, but byte-identity is **unproven** — the code
+  comment states the `path` parameter carries a home-folder prefix that is
+  wrong for WebDAV hrefs, directly contradicting ROUND21's "stale comment"
+  note. Needs a dedicated href-equivalence proof, not a perf banner.
+
+## Environment / methodology
+
+- `cargo run --release --features bench --example bench_round22_micro` —
+  counting global allocator, no Postgres. Tunable (env): `BENCH_ITERS` (200000).
+- Each section is BEFORE (verbatim replica of the shipped-before shape) vs AFTER
+  (verbatim replica of the shipped-after shape, which the source is then made to
+  match), with a byte/-value equivalence gate; the shipped source now matches
+  each AFTER arm.
+- Roll-back rule encoded per section: the harness `std::process::exit(1)`s with
+  `GATE FAIL … rollback` if an AFTER arm fails to reduce allocations.
+- Verified beyond the bench: `cargo clippy --features bench --all-targets -D
+  warnings` clean, `cargo fmt --all --check` clean, and `cargo test --lib
+  --features bench` = **529 passed / 0 failed** (incl. the OpenAPI-spec-validity
+  test that guards the H1 utoipa-handler signature change).

+# Round 23 — Postgres query-shape pass: typed JSONB decode, drive-policy borrow-deserialize, user-profile join!, subject-group CTE reuse, dedup unzip
+
+Benchmark-gated, same rule as ROUND2–22: every change ships with a BEFORE/AFTER
+benchmark and a value equivalence gate; an AFTER that doesn't beat its BEFORE is
+rolled back (never applied). This round is the **PostgreSQL** pass — the
+candidates the earlier rounds deferred as "needs a database to bench" — so it
+ships two harnesses:
+
+- **`bench_round23_micro`** (no Postgres) — the deterministic **allocation gate**
+  for the decode/clone candidates (counting global allocator; a non-winning
+  AFTER `std::process::exit(1)`s with `GATE FAIL … rollback`).
+- **`bench_round23_queries`** (live Postgres) — end-to-end **p50 latency** + a
+  strict **equivalence gate** (identical decoded rows / ids / user-sets from
+  BEFORE and AFTER; a mismatch exits 1) against seeded fixtures.
+
+Reproduce (the queries harness reads `DATABASE_URL` from `.env`):

+
+## Summary
+
+| # | change | metric | before → after |
+|--:|---|---|---|
+| **J1** | `contact_pg_repository::row_to_contact` (+ the inlined `contact_group_pg_repository` sibling) decoded each of the 3 JSONB columns (`email`/`phone`/`address`) with `row.get::<serde_json::Value>` + `serde_json::from_value::<Vec<Dto>>` — a throwaway `Value` DOM built per column and then walked a **second** time to produce the typed `Vec`. Now `row.try_get::<sqlx::types::Json<Vec<Dto>>>` decodes the JSONB bytes straight into the typed Vec in one `from_slice` pass, no DOM. Runs **per contact row** of every contact list / multiget / CardDAV sync. | micro allocs · PG p50 | **84 → 33 allocs/op** (2.15× wall) · **3794 → 2360 ns/contact** (1.61×) |
+| **J2** | `DrivePolicies::from_value` did `serde_json::from_value(value.clone())` — cloning the **entire** policies `Value` DOM before walking it, on every drive-policy read (move/copy, shared-link creation, grant). Now `DrivePolicies::deserialize(value)` deserializes straight from the borrow (serde_json's `Deserializer for &Value`), no clone — a one-line body change, byte-identical, all 7 call sites unchanged. | micro allocs | **5 → 0 allocs/op** (11.51× wall) |
+| **P1** | `AuthApplicationService::get_user_profile` issued two **independent, serial** `get_user_by_id` point reads (caller then target; the self-case short-circuit compares input UUIDs, not fetched data). Now the self-case does a single fetch and the non-self path overlaps caller+target with `tokio::join!` (`caller_res?` first preserves the caller-error precedence). | PG p50 | **577 → 312 µs/call** (1.85×) |
+| **G1** | `SubjectGroupService::remove_member` ran the child group's transitive-user recursive CTE **twice** for a nested `Group` removal — once in the would-empty pre-check, once in `invalidation_targets` after the remove. The edge delete is *above* the child, so its descendants can't change; now the CTE runs **once** and the result is reused for both. | PG p50 | **829 → 412 µs/removal** (2.01×) |
+| **U1** | `dedup_service` (`store_loose_chunks` final registration + the ingest `run_rollback`) built `Vec<String>`/`Vec<i64>` by **cloning** every 64-byte hash out of an owned, dead-after `Vec<(String,i64)>` purely to reshape for `sync_blobs(&[String])` + the `UNNEST` bind. Now `into_iter().unzip()` moves the hashes out — no per-hash content copy. | micro allocs | **256 → 0 hash clones** (1283 → 1027 allocs/op on a 256-chunk batch) |
+
+> The micro allocs/op is the deterministic gate (identical run to run); the PG
+> p50 is single-machine, warm-pool, and noise-bounded. Every section carries a
+> value-equivalence gate; the shipped source matches each AFTER arm.
+
+## [J1] Contact JSONB — typed `Json<T>` decode, no intermediate `Value` DOM
+
+`row_to_contact` (reached by 11 call sites — every contact GET / list /
+paginated list / multiget / CardDAV cursor stream / search / by-email /
+by-group / create+update RETURNING) and the identical inlined block in
+`contact_group_pg_repository::get_contacts_in_group` both did:
+
+```rust
+let email_json: JsonValue = row.get("email");        // sqlx JSONB → Value DOM (alloc tree)
+let emails = serde_json::from_value::<Vec<EmailPersistenceDto>>(email_json)  // walk the DOM again
+    .map(emails_from_persistence).unwrap_or_default();
+// … same for phone, address
+```
+
+`sqlx::types::Json<T>` decodes the raw JSONB bytes with a single
+`serde_json::from_slice::<T>` (sqlx-core 0.8.6 `types/json.rs`), skipping the
+`Value` tree entirely:
+
+```rust
+let emails = row
+    .try_get::<sqlx::types::Json<Vec<EmailPersistenceDto>>, _>("email")
+    .map(|j| emails_from_persistence(j.0))
+    .unwrap_or_default();
+```
+
+`try_get` (not `get`) preserves the exact malformed-shape fallback — `get`
+would panic on a decode error, whereas the old `from_value(...).unwrap_or_default()`
+tolerated it. The columns are `JSONB NOT NULL DEFAULT '[]'`, so SQL NULL never
+occurs. Byte-identical: both paths run the same derived `Deserialize<Vec<Dto>>`
+over the same bytes — the `bench_round23_queries` §Q1 gate asserts the two
+decode the 500 seeded contacts field-for-field identically. The micro shows the
+3 discarded DOMs/row (84 → 33 allocs); on the real rows the decode is 1.61×.
+
+## [J2] Drive policies — deserialize from the borrow, don't clone the DOM
+
+`DrivePolicies::from_value(value: &serde_json::Value)` is called on every
+drive-policy read (`get_policies_for_file/_folder`,
+`get_drive_id_and_policies_for_*`, `update_policies` RETURNING, the ACL engine's
+enforcement read, and `Drive::typed_policies`). It built the typed struct with
+`serde_json::from_value(value.clone())` — a full clone of the policies DOM
+purely because `from_value` consumes its argument. serde_json implements
+`Deserializer` for `&Value`, so the struct can be built straight from the
+borrow:
+
+```rust
+use serde::Deserialize as _;
+Self::deserialize(value).unwrap_or_default()   // was: serde_json::from_value(value.clone())
+```
+
+Byte-identical (same derived `Deserialize`, same lenient `unwrap_or_default`
+fallback that keeps unknown keys on disk), a one-line body change, and every
+caller keeps its `&Value` argument unchanged — so `typed_policies(&self)`
+(which only has a borrow of `self.policies`) also stops cloning. The micro
+(a realistic bag with a preserved unknown key) drops 5 → 0 allocs/op.
+
+## [P1] `get_user_profile` — overlap the two independent reads with `join!`
+
+The profile lookup fetched the caller and the target user in two serial
+round-trips. The self-case (`caller_id == target_id`) is decided by comparing
+the **input** UUIDs, so on the common non-self path the two reads are
+independent — query 2 never depends on query 1. AFTER:
+
+```rust
+if caller_id == target_id {                       // self: one fetch, unchanged
+    let caller = self.user_storage.get_user_by_id(caller_id).await?;
+    return Ok(UserDto::from(caller));
+}
+let (caller_res, target_res) = tokio::join!(       // non-self: overlap
+    self.user_storage.get_user_by_id(caller_id),
+    self.user_storage.get_user_by_id(target_id));
+let caller = caller_res?;                          // caller-error precedence preserved
+let target = match target_res { … };               // identical NotFound→anonymized-404 + audit
+```
+
+Every observable outcome is preserved (self still 1 fetch, the anti-enumeration
+audit unchanged). The §Q4 gate asserts identical ids from both shapes; two
+warm-pool serial reads vs the `join!` measured **1.85×**.
+
+## [G1] `remove_member` — compute the child's transitive users once, reuse it
+
+For a nested `GroupMember::Group(child_id)` removal the child's transitive-user
+set (a recursive `WITH RECURSIVE` CTE over `subject_group_members`) was computed
+**twice**: once in the would-empty self-defense pre-check, and again inside
+`invalidation_targets` after `remove_member` deleted the parent→child edge. That
+edge is *above* the child, so the child's own descendants are unchanged —
+verified empirically on the live DB (child set `{u2,u3}` identical before and
+after the edge delete). AFTER computes the CTE once, up front, and reuses it for
+both the pre-check and the cache-invalidation set (`invalidation_targets` stays
+for `add_member`). The §Q6 gate asserts the child set is both stable and the
+expected `{u2,u3}`; 2 CTEs vs 1 measured **2.01×** on the seeded 3-level tree.
+
+## [U1] dedup hash reshape — move via `unzip`, don't clone
+
+`store_loose_chunks`'s final registration and the ingest `run_rollback` both
+reshaped an owned `Vec<(String,i64)>` (dead after the block) into the
+`Vec<String>` + `Vec<i64>` that `sync_blobs(&[String])` and the `UNNEST` bind
+need, by cloning every 64-char hash:
+
+```rust
+let hashes: Vec<String> = new_rows.iter().map(|(h, _)| h.clone()).collect();  // N clones
+let sizes:  Vec<i64>    = new_rows.iter().map(|(_, s)| *s).collect();
+```
+
+Since the source is owned and never read again, `into_iter().unzip()` moves the
+hashes out — 0 per-hash content copies:
+
+```rust
+let (hashes, sizes): (Vec<String>, Vec<i64>) = new_rows.into_iter().unzip();
+```
+
+Byte-identical rows inserted; the micro (256 distinct new chunks) drops exactly
+the 256 hash clones. (This is the move-not-borrow refinement of the ROUND21 §R2
+`&[&str]` pattern — `sync_blobs` takes `&[String]`, so a borrow would force a
+port-signature change across 6 backends, whereas the move needs none.)
+
+## Not shipped — deferred to a dedicated pass
+
+- **`batch_operations::download_zip` per-item N+1** (the audit's #2, highest
+  raw-latency candidate): the file loop calls `get_file_with_perms` (itself
+  authz + `get_file` = 2 round-trips) per selected file, then
+  `add_file_entry_streamed` — which **re-authorizes** internally via
+  `get_file_stream_with_perms`. Collapsing the per-item metadata+authz into a
+  bulk `get_files_by_ids` + `check_files_read_batch` prefetch is a real win
+  (`2N+2M` serial round-trips → ~3 batch queries), **but** it moves the sole
+  authorization from before the stream to inside it, so it needs a careful
+  AuthZ-ordering + anti-enumeration proof (the project's rule: authz lives in
+  the service layer, denials audit-log and return the anti-enum shape). That is
+  its own validated pass, not a perf banner — queued with a `download_zip`
+  fixture that seeds a large multi-select and asserts identical ZIP entry
+  set+order across the change.
+- **Contact/Drive JSONB — the SQL-NULL edge**: the typed `try_get`/`deserialize`
+  paths return the empty/default on SQL NULL where the old `row.get::<Value>`
+  would have panicked. Both columns are `NOT NULL DEFAULT` today so this never
+  fires; noted only so a future nullable-column change re-checks it.
+
+## Environment / methodology
+
+- A local **PostgreSQL 16** dev instance was provisioned for this round
+  (schema applied via the 67 `migrations/*.sql` in order; `pg_trgm` + `ltree`
+  extensions). `bench_round23_queries` seeds its own fixtures (unique
+  `bench23-*` markers) and tears them down (idempotent cleanup) around the run.
+- **Build note:** this session's host intermittently `SIGILL`ed rustc/LLVM
+  codegen under the repo's default `-C target-cpu=native` (a `cascadelake` with
+  AVX-512 whose passthrough faulted after a host migration). All Round-23
+  builds/benches were run with `RUSTFLAGS="-C target-cpu=x86-64-v3"` (AVX2, no
+  AVX-512) to sidestep it. This is a local build-flag override only — the
+  checked-in `.cargo/config.toml` is unchanged, and the primary gate (allocs/op)
+  is target-cpu-independent; the PG p50 comparisons use the same flag for both
+  arms, so the relative speedups hold.
+- Each micro section: BEFORE (verbatim shipped-before shape) vs AFTER (verbatim
+  shipped-after shape) + a value-equivalence assert + a `GATE FAIL … rollback`
+  exit if the AFTER fails to reduce allocations. Each PG section: BEFORE vs
+  AFTER shape against real seeded rows + an equivalence gate (mismatch → exit 1)
+  + p50 over `BENCH_PASSES`.
+- Verified beyond the benches: `cargo fmt --all --check` clean, `cargo clippy
+  --features bench --all-targets -D warnings` clean, and the touched modules'
+  unit tests pass (`contact`, `drive`, `subject_group`, `dedup`, auth profile).

+# Round 24 — `download_zip` per-item authz+metadata N+1 → batch (validated authorization pass)
+
+This is the ROUND23 "not shipped" item #2, given the dedicated validated pass it
+needed. Unlike the other rounds it is **authorization-sensitive**, so the gate is
+not an allocation count or a latency floor — it is the **security property
+itself**: the batched authorization must make the *identical* per-file inclusion
+decision as the shipped-before per-file `require` loop, and must never let a
+denied or missing file into the archive.
+
+Reproduce (needs the dev Postgres up; reads `DATABASE_URL` from `.env`):
+
+```
+cargo run --release --features bench --example bench_round24_zip_authz
+```
+
+## The change
+
+`BatchOperations::download_zip` streamed a client's multi-selection into a ZIP.
+For the **individually-selected files** it looped, per file:
+
+```rust
+for file_id in &file_ids {
+    match self.file_retrieval.get_file_with_perms(file_id, user_id).await {   // require + get = 2 round-trips
+        Ok(file_dto) => { self.add_file_entry_streamed(&mut zip, file_id, &file_dto.name, &file_dto.mime_type, Some(user_id)).await … }
+        Err(_) => { /* skip + log */ }
+    }
+}
+```
+
+`get_file_with_perms` is `require_file` (a `Read` authz round-trip) **plus**
+`get_file` (a metadata round-trip) — so a selection of N files is **2N serial
+round-trips** before a single byte is streamed. AFTER routes the whole selection
+through one new service method:
+
+```rust
+let authorized = self.file_retrieval
+    .get_files_by_ids_with_perms(&file_ids, user_id).await?;      // 1 batch check + 1 batch get
+let by_id: HashMap<Uuid, FileDto> = authorized.into_iter()
+    .filter_map(|f| Uuid::parse_str(&f.id).ok().map(|u| (u, f))).collect();
+for file_id in &file_ids {                                        // same input order
+    let Some(file_dto) = Uuid::parse_str(file_id).ok().and_then(|u| by_id.get(&u)) else {
+        info!("Skipping file {file_id} (not accessible or missing)"); continue;
+    };
+    self.add_file_entry_streamed(&mut zip, file_id, &file_dto.name, &file_dto.mime_type, Some(user_id)).await …
+}
+```
+
+`FileRetrievalService::get_files_by_ids_with_perms` authorizes every id in ONE
+`AuthorizationEngine::check_files_read_batch` (the `PgAclEngine` override resolves
+all files' drives in a single query and reuses the per-drive role cache) and
+fetches only the authorized ids in ONE `get_files_by_ids`. **2N round-trips → 2.**
+
+### Why this is authorization-safe (the part that made it a dedicated pass)
+
+Three properties had to hold, all verified against the source before touching it:
+
+1. **Authorization still happens before any ZIP entry is written.**
+   `add_file_entry_streamed` writes the entry header (the **filename**) *before*
+   it opens the authorized stream (`write_entry_stream` then
+   `get_file_stream_with_perms`). So the pre-filter is load-bearing: a denied
+   file must never reach `add_file_entry_streamed`, or its name would leak into
+   the archive (and leave a dangling entry). AFTER preserves this exactly — a
+   denied/missing id is absent from `by_id`, so it is `continue`-skipped and
+   never reaches the entry write. The authz simply moved from a per-file
+   `require` to one batch `check` **earlier** in the same function, not into or
+   after the stream.
+
+2. **The per-file stream-open Read check + Recents recording are unchanged.**
+   `add_file_entry_streamed(Some(user_id))` still calls
+   `get_file_stream_with_perms`, which re-checks `Read` (now a primed-cache hit —
+   `check_files_read_batch` seeds the resource→drive cache) and records the
+   access in Recents. The old loop double-notified Recents (once in
+   `get_file_with_perms`, once in the stream open) and the throttle coalesced it
+   to one entry; AFTER notifies once (the stream open) — identical net effect.
+
+3. **The batch authorization is identical to looping `require`.**
+   `check_files_read_batch` is documented and gated as "semantically identical to
+   looping `check`", and `require(Read)` succeeds iff `check(Read)` is true (a
+   denied `Read` is the 404 anti-enumeration shape). The §validation gate proves
+   this empirically on a mix of granted / denied / missing ids.
+
+The **folder** selections (`get_folder_with_perms` per root, then the already-bulk
+`add_folder_subtree_to_zip`) are left as-is: root counts are small and there is no
+`check_folders_read_batch` primitive to batch through — see *Not shipped*.
+
+## The validation
+
+`bench_round24_zip_authz` drives the **real `PgAclEngine`** (the `fresh_engine`
+shape from `bench_favorites_authz`) against a seeded fixture designed to exercise
+every inclusion outcome:
+
+- `owned` — N files on **drive A**, which the caller holds an `editor` grant on → **must be INCLUDED**
+- `denied` — N files on **drive B**, which the caller has **no** grant on → **must be DENIED**
+- `missing` — N random UUIDs that don't exist → **must be MISSING**
+
+interleaved `owned, denied, missing, owned, …` so the **order** test is real. The
+gate asserts, and `exit(1)`s on any failure:
+
+- `before_included` (the per-file `require` filter, in input order) **==**
+  `after_included` (the batch `check_files_read_batch` filter, in input order) —
+  identical **set and order**;
+- the included set is **exactly** the caller's `owned` files;
+- **no** `denied` (other-drive) file is included — the authz-regression tripwire;
+- **no** `missing` id is included;
+- the batch `get_files_by_ids` of the authorized ids returns **exactly** the
+  `owned` files.
+
+Latency (cold engine, empty caches — the first-download shape), `BENCH_FILES=200`
+(600-item interleaved selection, ⅓ owned / ⅓ denied / ⅓ missing):
+
+| arm | wall (600 items) | per file |
+|---|---|---|
+| per-file `require` loop | 559.47 ms | 932.45 µs |
+| batch `check_files_read_batch` | 266.58 ms | 444.30 µs |
+
+**2.10×** — and this is the *conservative* case: with ⅓ of the ids on a drive
+the caller has no role on, `check_files_read_batch` still falls back to a per-file
+`check_inner` for each un-readable-drive file. The realistic "download my own N
+files" selection is **all** on drives the caller has a role on, where the batch
+is genuinely O(1) (one drive-resolve query + cached role checks) against the
+loop's 2N round-trips — a far larger win.
+
+## Not shipped
+
+- **Folder selections** (`download_zip`'s folder loop): `get_folder_with_perms`
+  per selected root. Root counts are typically 1–3, and there is no
+  `check_folders_read_batch` batch-authz primitive (only files have one), so
+  batching would still loop `check` per root — no round-trip win. Left as-is.
+- **Dropping the stream-open re-check**: since the batch pre-check already
+  authorized (and primed the cache), `add_file_entry_streamed`'s
+  `get_file_stream_with_perms` re-check is now redundant (a cache hit). Replacing
+  it with the no-perms `get_file_stream` would save the cache lookups but would
+  also drop the Recents recording and the second authz barrier — not worth the
+  behavior change; kept as belt-and-suspenders.
+
+## Environment / methodology
+
+- Real `PgAclEngine` + `FileBlobReadRepository` against a local **PostgreSQL 16**
+  (schema from `migrations/`). The bench seeds its own two-drive fixture
+  (`bench_zipauthz_*` markers) and tears it down around the run.
+- Built with `RUSTFLAGS="-C target-cpu=x86-64-v3"` (this session's host
+  intermittently `SIGILL`ed rustc under the repo's default `-C target-cpu=native`
+  AVX-512 after a host migration — see benches/ROUND23.md). Local build-flag
+  override only; the checked-in `.cargo/config.toml` is unchanged.
+- The gate is the security equivalence (set + order + denied/missing exclusion),
+  not a perf threshold; the latency table is supporting evidence for the
+  round-trip collapse.
+- Verified beyond the bench: `cargo clippy --features bench --all-targets
+  -D warnings` clean, `cargo fmt --all --check` clean, `cargo test --lib
+  --features bench` = 529 passed / 0 failed.

+# Round 25 — encrypted-read in-place decrypt (RAM), delta-commit hash move, dead folder-Query, public-playlist N+1 fold, contact vcard over-fetch
+
+This round lands a cross-cutting perf pass surfaced by a fresh six-way audit of
+the tree (dedup/upload, blob-I/O, DB query-shape, HTTP/DAV emitters, auth/global
+config, frontend), cross-referenced against everything ROUND2–24 already shipped
+so nothing here re-treads landed work. Five items ship, each behind a
+BEFORE/AFTER benchmark that `std::process::exit(1)`s ("`GATE FAIL … rollback`")
+unless AFTER strictly beats BEFORE — the round's roll-back rule encoded into the
+benchmark, so an AFTER that doesn't win is never applied to the source.
+
+Reproduce:
+
+```bash
+# M1–M3 — counting global allocator (count + BYTES), no Postgres
+RUSTFLAGS="-C target-cpu=x86-64-v3" \
+  cargo run --release --features bench --example bench_round25_micro
+
+# Q1–Q2 — live dev Postgres (reads DATABASE_URL from .env)
+RUSTFLAGS="-C target-cpu=x86-64-v3" \
+  cargo run --release --features bench --example bench_round25_queries
+```
+
+The two headline items match the owner's top priorities: **M1 halves peak RAM on
+every encrypted blob read**, and **Q1 collapses the public-playlist gallery from
+101 DB round-trips to 1**.
+
+---
+
+## [M1] `EncryptedBlobBackend::decrypt_bytes` — full ciphertext copy → in-place detached decrypt (RAM)
+
+`decrypt_bytes` claimed in its own doc comment to decrypt "**in place** … the
+ciphertext buffer is reused for the plaintext instead of allocating a second
+copy." It did not:
+
+```rust
+let mut ciphertext = encrypted.split_off(NONCE_SIZE); // allocates + memcpy's the whole tail
+```
+
+`Vec::split_off(12)` allocates a fresh `Vec` sized `len-12` and `ptr::copy`s the
+entire ciphertext+tag into it — so **every decrypted CDC chunk (≤ 1 MiB), and
+every legacy whole-file blob, paid one full-payload allocation + memcpy on read**.
+ROUND11 §15 fixed the *encrypt* side (`encrypt_in_place_detached`) but the
+decrypt side was never given the same treatment; the stale doc comment is the
+tell that it was believed already done.
+
+AFTER lifts the 12-byte nonce and 16-byte GCM tag to the stack, decrypts the
+middle in place via `decrypt_in_place_detached` (the detached API already used by
+the encrypt side), and returns a **zero-copy `Bytes::slice` past the nonce** — no
+extra allocation, no full-payload copy. Plaintext bytes are identical.
+
+| arm    | allocs/op | bytes/op | note |
+|--------|----------:|---------:|------|
+| BEFORE |      3.00 |  524 356 | input clone + `split_off` copy + `Bytes::from` |
+| AFTER  |      2.00 |  262 196 | input clone + `Bytes::from` only |
+
+**−262 160 bytes/op** at a 256 KiB payload — the copied ciphertext eliminated;
+peak heap on a decrypt drops from ~2× to ~1× the payload. The win scales with
+payload, so a legacy whole-file blob read no longer transiently doubles a
+multi-hundred-MB allocation. Gate: **AFTER bytes/op strictly lower** (it is). The
+equivalence arm asserts the decrypted plaintext is byte-identical to the
+`split_off` path across the short-input edge, 64 KiB and 1 MiB.
+
+## [M2] Delta commit — third per-occurrence hash clone → move-unzip (dedup allocations)
+
+`delta_upload_service::commit_with_perms` owns `request: DeltaCommitRequest`, yet
+materialized the per-occurrence chunk-hash list a **third** time at the manifest
+bind (after the distinct set and the verification tuple):
+
+```rust
+let chunk_hashes: Vec<String> = request.chunks.iter().map(|c| c.h.clone()).collect();
+let chunk_sizes:  Vec<u64>    = request.chunks.iter().map(|c| c.s).collect();
+```
+
+`request.chunks` is dead after this line (only `request.file_hash` is read
+below), so AFTER moves the hashes out instead of cloning each 64-char hash:
+
+```rust
+let (chunk_hashes, chunk_sizes): (Vec<String>, Vec<u64>) =
+    request.chunks.into_iter().map(|c| (c.h, c.s)).unzip();
+```
+
+| arm    | allocs/op (4000 chunks) | bytes/op |
+|--------|------------------------:|---------:|
+| BEFORE |                 8 003.00 |  768 000 |
+| AFTER  |                 4 003.00 |  512 000 |
+
+**−4000 allocs/op** (the N hash-String clones) on the flagship "upload only what
+changed" path. Gate: AFTER allocs/op strictly lower. Equivalence: the produced
+`(chunk_hashes, chunk_sizes)` are element-equal to the clone-collect arms.
+
+## [M3] `folder_handler::download_folder_zip` — dead `Query<HashMap>` extractor removed (allocations)
+
+Both the route wrapper and `download_folder_zip_impl` bound
+`Query<HashMap<String,String>>` as `_params` and discarded it — the handler reads
+only the path `id`. axum's `Query` extractor parses the whole query string into a
+`HashMap` plus an owned `String` key and value per param, all dropped unread. AFTER
+deletes the extractor; axum ignores any query string when none is present, so the
+response is byte-identical.
+
+| arm    |  ns/op | allocs/op | bytes/op |
+|--------|-------:|----------:|---------:|
+| BEFORE | 212.1  |      5.00 |      268 |
+| AFTER  |   0.3  |      0.00 |        0 |
+
+Pure dead-work elimination (**614× wall**, 5 → 0 allocs) whenever a client
+appends any query string (cache-buster, tracking param). Gate: AFTER allocs/op
+strictly lower.
+
+## [Q1] Public-playlist listing — 1 + N `COUNT(*)` → one `LEFT JOIN … GROUP BY` (DB round-trips)
+
+`MusicStorageAdapter::list_public_playlists` ran one listing SELECT then one
+`SELECT COUNT(*) FROM audio.playlist_items WHERE playlist_id = $1` **per returned
+playlist** — up to **101 serial round-trips** for a `limit=100` gallery page.
+AFTER folds the count into the listing with a single
+`LEFT JOIN audio.playlist_items … GROUP BY p.id`, exposed as a new inherent
+`PlaylistPgRepository::list_public_playlists_with_counts` returning
+`(Playlist, track_count)` — backed by the existing
+`idx_playlist_items_playlist_id`. (The adapter holds the concrete repo type, so
+no trait change was needed; the two sibling 1+N adapter methods have no live
+caller and are left untouched.)
+
+Live Postgres, 100 public playlists (varying track counts), p50 over 30 passes:
+
+| arm    | p50 ms | round-trips |
+|--------|-------:|------------:|
+| BEFORE | 16.572 |         101 |
+| AFTER  |  0.458 |           1 |
+
+**36.2× wall, 101 → 1 round-trips.** Equivalence: the `(playlist → track_count)`
+map is identical BEFORE vs AFTER (asserted; mismatch `exit(1)`s). Gate: AFTER p50
+strictly lower. On a remote/managed Postgres, where each round-trip is a network
+RTT rather than a local socket hop, the win is far larger than the localhost 36×.
+
+## [Q2] Contact REST listings — stop over-fetching the multi-KB `vcard` TEXT (bandwidth)
+
+`get_contacts_by_address_book_paginated`, `search_contacts` and
+`get_contacts_by_group` all `SELECT … vcard …` — the full serialized vCard TEXT,
+the largest column (can embed a base64 `PHOTO` of tens of KB). But every caller
+maps `Contact → ContactDto`, which has **no vcard field**, so it is fetched,
+shipped over the wire, decoded into a `String` and immediately dropped. AFTER
+adds a `row_to_contact_lite` mapper (shared `row_to_contact_with_vcard` core, no
+duplication) that supplies an empty vcard, and narrows those three SELECTs to
+omit the column. The shared `get_contacts_by_address_book` (also used by the
+whole-book vCard export) and the CardDAV sync/multiget paths keep the column.
+
+Live Postgres, 1000 contacts each carrying an 8 KiB vCard, p50 over 20 passes:
+
+| arm    | p50 ms | note |
+|--------|-------:|------|
+| BEFORE | 10.010 | SELECT incl. vcard, decoded + dropped |
+| AFTER  |  1.570 | SELECT without vcard |
+
+**6.4× wall** — and the win is bytes-on-the-wire + per-row `String` allocation,
+both of which grow with vCard size (photos push these to tens of KB each).
+Equivalence: the kept DTO fields `(id, full_name, photo_url)` are identical
+across the change (asserted). Gate: AFTER p50 strictly lower.
+
+---
+
+## Not shipped — verified this round, deferred to a later pass
+
+The six-way audit surfaced far more than shipped here; the following were
+verified real against current source and carry a benchmark plan, but each needs a
+multi-signature change, a remote-backend fixture, an operator-facing decision, or
+its own validated pass. Grouped by area for the next rounds.
+
+### Blob-I/O / disk (owner priority)
+- **`CachedBlobBackend::initialize` never pre-creates the 256 shard dirs** (the
+  line-122 comment says it does; it only makes `cache_dir`), so all three cache
+  writes pay a per-chunk `create_dir_all(parent)` — a wasted `mkdirat(EEXIST)` +
+  component stat + blocking-pool dispatch on cached-remote deployments. Fix mirrors
+  `LocalBlobBackend::initialize`'s `HEX_PREFIXES` loop; gate on a `strace -c`
+  `mkdirat` count + wall on tmpfs. (conf 0.9)
+- **Eviction listener unlinks with a blocking `std::fs::remove_file` on the tokio
+  worker** (`cached_blob_backend.rs:98`) — `moka::sync` runs the listener inline on
+  the inserting worker; every write-through eviction blocks a reactor thread on
+  `unlink(2)`. Hand off via `spawn_blocking`/a drain task; gate on p99 scheduling
+  delay under eviction pressure. (conf 0.85)
+- **S3 reads copy every served byte** through `into_async_read()+ReaderStream`
+  (`s3_blob_backend.rs:261/298`) while Azure already forwards SDK `Bytes` frames
+  zero-copy — needs a MinIO/stub fixture to gate. (conf 0.6)
+- **`store_loose_chunks` writes loose chunks to the backend serially** while the
+  main ingest overlaps 8 (`buffer_unordered`); on a remote backend the delta path
+  serializes RTTs the main path hides. Needs a latency-stub backend. (conf 0.5)
+- **`local_blob_path` does a synchronous `path.exists()` stat on the reactor** —
+  wants an async port variant. (conf 0.6)
+- **`PLAINTEXT_EMIT_SIZE` = 64 KiB vs the 256 KiB every other backend streams** —
+  quarters the encrypted-read frame count; the "parity" comment justifying 64 KiB
+  is factually wrong. Wants a streaming A/B (frame count + wall). (conf 0.5)
+
+### DB query-shape
+- **Drive-policy reads decode through a throwaway `serde_json::Value` DOM**
+  (`drive_pg_repository.rs` 4 methods) — ROUND23 §J2 removed only the clone, not the
+  DOM; fold to `sqlx::types::Json<DrivePolicies>` like §J1. Fires on move/copy and
+  every share/grant create. (conf 0.75)
+- **Contact create/update build a throwaway `Value` before binding JSONB** (the
+  write-side twin of ROUND23 §J1) — bind `sqlx::types::Json(&dtos)` directly. (conf 0.6)
+
+### Dedup / upload
+- **`attach_manifest` reshapes chunk sizes into a throwaway `Vec<i64>` per upload**
+  — carry sizes as `i64` end-to-end (validated in an earlier draft of
+  `bench_round25_micro` §M4; deferred because it threads a type change through
+  `ChunkIngestOutcome`, the delta/stream/legacy paths and the `total_size` sums —
+  its own pass). (conf 0.5)
+- **`store_from_stream` rebuilds the distinct-hash set the CDC loop already held**
+  as `pinned ∪ written` (`dedup_service.rs:499`/`distinct_hashes`) — return the list
+  the ingest already owns instead of an O(N) rescan + HashSet + N clones. ROUND14
+  deferred. (conf 0.55)
+- **Whole-file dedup-hit fast path is 3 serial manifest round-trips** (owner-check +
+  metadata SELECT + ref-bump UPDATE) — fold metadata+bump into one
+  `UPDATE … RETURNING` (3→2), or the whole thing into one atomic statement (3→1,
+  also closes a TOCTOU). Authz-sensitive; needs a validated pass. (conf 0.55)
+- **Ownership checks bind the caller UUID as text** (`to_string()` + `$2::uuid`)
+  instead of a native `Uuid`, unlike the sibling claimable/pin queries. (conf 0.5)
+- **Delta-download authorize is 2 round-trips** (entitlement then sizes) foldable
+  into one entitlement-JOIN-blobs query. (conf 0.55)
+
+### HTTP / DAV emitters (allocations)
+- **`format_oc_id` allocates a fresh `String` per NC PROPFIND/REPORT/trashbin row**
+  — thread a `format_oc_id_into(&mut String, …)` buffer like the href buffer already
+  in those loops. Multi-signature; ROUND20 deferred. (conf 0.85)
+- **`search_service::suggest_with_perms` builds a full `FileDto`/`FolderDto` per
+  candidate** to read 5 fields, computing (and dropping) `etag` + `size_formatted`
+  Strings on every keystroke. (conf 0.75)
+- **CardDAV whole-book GET accumulates a throwaway per-contact vCard `String`** into
+  an unsized buffer — wants a `write_vcard_into(&mut String, …)`. (conf 0.7)
+- **NC REPORT/trashbin per-row href + NC avatar `HeaderMap` clone + `list_files_query`
+  `Query<HashMap>`** — the remaining H1/href-buffer items ROUND22 left. (conf 0.55–0.65)
+
+### Auth / global config
+- **`foldhash` is already in the lockfile transitively** (via hashbrown), so the
+  long-deferred fast-hasher lead is nearly free: `foldhash::quality::RandomState`
+  (random-seeded, DoS-safe) for the attacker-controlled delta-upload hash sets, and
+  `foldhash::fast` for the trusted-key NC PROPFIND `favorite_ids`/`nc_id` maps.
+  Wall-gated (a hasher swap changes 0 allocations). (conf 0.7)
+- **`tracing` has no `release_max_level` feature** — per-request `debug!`s in the
+  auth middleware and the authz `require()` granted path compile into release and
+  pay a runtime level check. `release_max_level_info` compiles them out (binary-size
+  + hot-path win) but silently disables `RUST_LOG=debug` on release builds — an
+  **operator-facing tradeoff** that wants a maintainer decision, so it is flagged, not
+  shipped. (conf 0.65)
+- **`profile.release` uses `lto = "thin"`** while `profile.bench` already trusts
+  `lto = "fat"` — a last-slice hot-path + size win at the cost of link time. (conf 0.55)
+- **`panic = "abort"` — VERIFIED UNSAFE, do not apply.** `text_extractor.rs:177`
+  relies on `catch_unwind` to survive `pdf-extract` panics on malformed PDFs, and
+  tokio's per-task panic isolation itself needs unwinding; under abort a single
+  hostile PDF (or any handler `.unwrap()`) becomes a whole-process crash. Keep
+  `panic = "unwind"`. (Recorded so a future pass doesn't re-open it.) (conf 0.9)
+
+### Frontend
+- **Client folder-listing cache (`getCachedFolder`/`cacheFolder` + ETag) is dead
+  code** — never called; every folder navigation refetches the full body with
+  `cache:'no-store'` and no `If-None-Match`. Wire the SWR cache in (bandwidth +
+  instant paint on revisits). (conf 0.6)
+- **Grouped listing views mount one `VirtualWindow` per section** — O(sections)
+  scroll listeners + `getBoundingClientRect` reads per scroll frame; hoist to one
+  shared tracker (the deferred "unify onto VirtualRows"). (conf 0.6)
+- **`VirtualRows.offsets` prefix-sum, flat dotfile filter O(N²), `typeLabel`
+  per-call 13-entry object** — the residual per-page frontend rebuilds. (conf 0.5–0.65)
+
+---
+
+## Environment / methodology
+
+- **M1–M3:** counting global allocator tracking BOTH alloc **count** and **bytes**
+  (`examples/bench_round25_micro.rs`), no Postgres. Each section is BEFORE
+  (verbatim replica of the shipped-before shape) vs AFTER (replica of the
+  shipped-after shape, which the source now matches), with a value-equivalence
+  assertion and a `GATE FAIL … rollback` `exit(1)` if the AFTER arm fails to beat
+  BEFORE on its gate metric (M1 gates on bytes/op — the RAM win; M2/M3 on allocs/op).
+  Tunables: `M1_ITERS` (2000), `PAYLOAD` (262144), `CHUNKS` (4000), `BENCH_ITERS` (200000).
+- **Q1–Q2:** live dev **PostgreSQL 16** (schema from `migrations/`), reads
+  `DATABASE_URL` from `.env`. Each section seeds its own fixture (`bench25_*` /
+  `bench25-*` markers, torn down around the run), asserts an equivalence gate
+  (result set identical BEFORE vs AFTER — mismatch `exit(1)`s), and gates on p50
+  wall strictly decreasing. Q1's `playlist_items.file_id` FK is bypassed during
+  seeding with `session_replication_role = replica` (superuser) purely to isolate
+  the query shape without a `storage.files` fixture. Tunables: `Q1_PLAYLISTS` (100),
+  `Q1_PASSES` (30), `Q2_CONTACTS` (1000), `Q2_PASSES` (20), `Q2_VCARD_KB` (8).
+- Built with `RUSTFLAGS="-C target-cpu=x86-64-v3"` (the checked-in
+  `.cargo/config.toml` pins `target-cpu=native`, which `SIGILL`s on this session's
+  host under AVX-512 — see ROUND23/24; local build-flag override only, the config
+  is unchanged).
+- Verified beyond the benches: `cargo fmt --all --check` clean,
+  `cargo clippy --features bench -- -D warnings` clean, and the contact / playlist /
+  encrypted-backend / delta-upload unit tests pass.

+# Round 26 — drive-policy JSONB decode (alloc), CachedBlobBackend shard-dir pre-create (disk), delta-upload foldhash (CPU); eviction-unlink off-reactor tested & reverted
+
+This round drains three high-confidence items from the ROUND25 backlog, each
+behind a BEFORE/AFTER benchmark that `std::process::exit(1)`s ("`GATE FAIL …
+rollback`") unless AFTER strictly beats BEFORE. A fourth candidate (moving the
+cache eviction unlink off the reactor) was **tested and reverted** — the
+benchmark refuted it. All three shipped items target the owner's priorities:
+allocations, disk-I/O, and CPU.
+
+Reproduce:
+
+```bash
+RUSTFLAGS="-C target-cpu=x86-64-v3" cargo run --release --features bench --example bench_round26_micro   # P1
+RUSTFLAGS="-C target-cpu=x86-64-v3" cargo run --release --features bench --example bench_round26_diskio  # D1
+RUSTFLAGS="-C target-cpu=x86-64-v3" cargo run --release --features bench --example bench_round26_hasher   # G1
+```
+
+---
+
+## [P1] Drive-policy reads: throwaway `serde_json::Value` DOM → `from_slice::<DrivePolicies>` (allocations)
+
+`drive_pg_repository`'s four policy reads (`get_policies_for_file/_folder`,
+`get_drive_id_and_policies_for_file/_folder`) fetched `d.policies` as a
+`serde_json::Value` and then called `DrivePolicies::from_value(&raw)`
+(`Self::deserialize(&Value)`). The `Value` tree — a `Map` + a boxed `String` key
++ a `Value` node per policy field — is built once, walked once, and dropped. This
+is the exact throwaway-DOM pattern ROUND23 §J1 removed for contacts; §J2 removed
+only the `from_value` *clone*, not the DOM. These reads fire on file/folder
+move & copy and on every share/grant creation.
+
+AFTER fetches through `sqlx::types::Json<DrivePolicies>` — one
+`serde_json::from_slice::<DrivePolicies>` over the raw JSONB bytes, no
+intermediate DOM — via a shared `policies_from_row` helper that preserves the
+lenient `unwrap_or_default` fallback exactly (a malformed bag → all-false,
+`try_get(...).unwrap_or_default()`, mirroring §J1).
+
+| arm    |  ns/op | allocs/op | bytes/op |
+|--------|-------:|----------:|---------:|
+| BEFORE | 399.4  |      6.00 |      719 |
+| AFTER  | 161.0  |      0.00 |        0 |
+
+**6 → 0 allocs/op, −719 bytes/op, 2.48× wall** — the entire Value DOM removed per
+policy read. Gate: AFTER allocs/op strictly lower. Equivalence: the decoded
+`DrivePolicies` is asserted identical BEFORE vs AFTER.
+
+## [D1] `CachedBlobBackend`: pre-create the 256 shard dirs at init, drop the per-write `create_dir_all` (disk-I/O)
+
+`CachedBlobBackend::initialize` created only `cache_dir`, never the 256
+`{00..ff}` shard dirs (the line-122 comment claimed otherwise). So all three
+cache-write sites (`cache_bytes_write_through`, `insert_into_cache`,
+`fetch_and_cache`) re-ran `tokio::fs::create_dir_all(parent)` per chunk — a
+wasted `mkdirat(EEXIST)` + component stat + blocking-pool dispatch on a shard
+that already exists, on every cached-remote write. AFTER creates all 256 shards
+once at init (mirroring `LocalBlobBackend::initialize`, reusing its
+`HEX_PREFIXES` table) and deletes the three per-write calls; the shard for any
+`&hash[..2]` prefix always exists, so the writes just `fs::write`/`fs::copy`.
+
+Measured on a tmpfs tempdir (`create_dir_all` on an already-existing shard vs the
+skip):
+
+| arm    | ns/write |
+|--------|---------:|
+| BEFORE |  44 801.8 |
+| AFTER  |      0.3 |
+
+**~45 µs removed per cache write.** Gate: AFTER ns/write strictly lower. The
+on-disk layout is identical; the directory creation simply moved from the hot
+path to one-time startup.
+
+## [G1] Delta-upload have/need hash sets: SipHash → `foldhash::quality::RandomState` (CPU)
+
+The delta-upload negotiation builds `HashSet`s over up to `max_chunk_count()`
+client-supplied 64-hex BLAKE3 hashes per request (`distinct_hashes`, and
+`authorize_chunk_download`'s `distinct_seen`). std `HashSet` uses SipHash-1-3 —
+DoS-resistant but ~2-4× slower than a modern hash on short keys. AFTER uses
+`foldhash::quality::RandomState`, a fast non-cryptographic hasher that **stays
+DoS-resistant** because it is per-instance random-seeded — the required property
+for these *attacker-controlled* inputs (not `FxHash`/a fixed seed). `foldhash` is
+already in the lockfile transitively (via `hashbrown`), so the direct dep adds no
+newly-compiled crate.
+
+Build + membership scan over 40 000 client hashes, p50 over 50 passes:
+
+| arm               | p50 ms (build+scan) |
+|-------------------|--------------------:|
+| BEFORE (SipHash)  |               4.768 |
+| AFTER (foldhash)  |               2.007 |
+
+**2.37× wall** on the delta negotiation's hottest set — a bulk sync of a large
+file negotiates thousands of chunks. Scales with `max_chunk_count()`.
+
+Gate: AFTER p50 wall (build set + membership scan over N hashes) strictly lower,
+**and** two `RandomState::default()` instances must produce different hashes for
+the same key (asserting the random per-instance seed — DoS resistance retained).
+The set membership decisions are unchanged, so behaviour is identical.
+
+---
+
+## Tested and reverted
+
+- **[D2] Move the cache eviction unlink off the reactor via `spawn_blocking`.**
+  The moka eviction listener unlinks a size-evicted blob with a synchronous
+  `std::fs::remove_file` inline on the tokio worker that triggered the insert.
+  The hypothesis: hand it to `spawn_blocking` so the reactor isn't blocked on
+  `unlink(2)`. The benchmark refutes it on the relevant configuration:
+
+  | arm                         | ns on reactor / eviction |
+  |-----------------------------|-------------------------:|
+  | BEFORE (inline remove_file) |                  7 055.7 |
+  | AFTER (spawn_blocking)      |                 19 848.1 |
+
+  `CachedBlobBackend` caches on a **local** dir (fast unlink, ~7 µs), and
+  `spawn_blocking`'s task-dispatch overhead (~20 µs) costs *more* on the reactor
+  than the inline unlink it replaces — a net loss. The original code comment ("a
+  quick unlink on the inserting task's thread, off the hot get path") is correct
+  for the fast-local-cache case. A win would only materialize on genuinely slow
+  storage (network-backed cache dir), which there is no fixture for here.
+  **Reverted; kept the inline unlink.** (A "measure before believing" result, like
+  BASELINE's dropped Task 2.1 / reverted Phase 1.7.)
+
+## Not shipped — carried forward
+
+Named in the ROUND25 backlog, still queued (each wants a multi-signature change,
+a remote-backend fixture, or a different toolchain):
+
+- **`format_oc_id_into` buffer** through the NC PROPFIND/REPORT/trashbin emit
+  loops — a per-row `String` → reused buffer. Threads a buffer through ~4 loop
+  sites across 3 files and depends on `NextcloudFileIdService`'s instance-id
+  format; wants its own validated pass so a wrong `oc:id` can't reach a client.
+- **S3 read zero-copy forward** (`into_async_read()+ReaderStream` → forward the
+  SDK `Bytes` frames, Azure-style) — needs a MinIO/stub `ByteStream` fixture.
+- **Frontend folder-listing cache** (`getCachedFolder`/`cacheFolder` is dead
+  code; every navigation refetches with `cache:'no-store'`) — a SvelteKit/Vitest
+  pass (bandwidth + instant paint on revisits).
+- **foldhash for the NC PROPFIND trusted-key maps** (`favorite_ids`, `nc_id`) —
+  `foldhash::fast` (no random seed needed; server-generated keys). Threads the
+  hasher type through the emit-loop map builders.
+- **Contact create/update `Json<T>` bind** (write-side twin of §J1) and the other
+  ROUND25 backlog items.
+
+## Environment / methodology
+
+- **P1:** counting global allocator (count + bytes), no Postgres. The real
+  `DrivePolicies` type is imported from the crate; BEFORE replicates the shipped
+  `serde_json::from_slice::<Value>` + `deserialize(&Value)`, AFTER the shipped
+  `from_slice::<DrivePolicies>`. Value-equivalence asserted; gate on allocs/op.
+- **D1:** async wall on a tmpfs `tempfile::tempdir`; BEFORE = `create_dir_all` on
+  a pre-existing shard, AFTER = the skip. Gate on ns/write.
+- **G1:** wall-gated (a hasher swap changes 0 allocations); SipHash vs
+  `foldhash::quality` build+scan over N random 64-hex hashes; DoS-seed assertion.
+- Built with `RUSTFLAGS="-C target-cpu=x86-64-v3"` (the checked-in
+  `.cargo/config.toml` pins `target-cpu=native`, which `SIGILL`s on this host —
+  see ROUND23/24; local override only).
+- Verified beyond the benches: `cargo fmt --all --check` clean,
+  `cargo clippy --features bench -- -D warnings` clean, `cargo test --lib
+  --features bench` green.

+

+unless AFTER allocates strictly fewer than BEFORE.

+
+## [H1] NextCloud PROPFIND: per-row `oc:id` String → one reused buffer per page
+
+The streaming PROPFIND page loops built `oc:id` as a fresh `String` per child —
+`format_oc_id(id, svc)` = `format!("{:08}{}", id, instance_id)` — then passed
+`oc_id.as_deref()` into `write_{file,folder}_response`. The sibling per-row costs
+(href, etag, dates) were already reduced to a reused buffer / borrowed events
+(ROUND19 §M6, ROUND20 §C1); `oc:id` was explicitly left as the last per-row
+String (ROUND20 deferred). AFTER adds `format_oc_id_into(&mut out, id, svc)` (the
+0-alloc form) and computes into one `oc_buf` reused across the page, alongside the
+existing `href` buffer — **1 String/row → 0** (amortized to one buffer per page).
+The write functions still take `Option<&str>`, so their signatures don't change;
+the emitted `oc:id` bytes are identical.
+
+Scoped to the two **PROPFIND** page loops (the hot directory-listing path — the
+most common NextCloud operation). The lower-traffic REPORT/trashbin sites and the
+single-emit self-response sites are left as `format_oc_id` (see *Not shipped*).
+
+| arm    |    ns/op | allocs/op |
+|--------|---------:|----------:|
+| BEFORE | 34 185.3 |  1 000.00 |
+| AFTER  | 14 484.9 |      2.00 |
+
+**998 → 0 per-row allocs (2 amortized buffers for the whole page), 2.36× wall**
+over a 500-row page. Gate: AFTER allocs/op strictly lower. Equivalence: the
+`oc:id` bytes from the reused buffer match `format_oc_id` for every id.
+
+## [P2] Contact create/update: throwaway `serde_json::Value` DOM → `Json(&dtos)` direct serialize
+
+`contact_pg_repository::{create,update}_contact` built a throwaway
+`serde_json::Value` per JSONB column (`serde_json::to_value(&email_dtos)` etc.)
+and bound that — sqlx re-serializes the `Value` to JSONB bytes at encode time, so
+the flow was `DTOs → Value DOM (alloc) → bytes`, the tree discarded. AFTER binds
+`sqlx::types::Json(&dtos)`, whose `Encode` runs `serde_json::to_writer` on the
+borrowed value straight into the JSONB buffer — no intermediate DOM. This is the
+write-side twin of the read-side ROUND23 §J1 fix. The old
+`.unwrap_or(JsonValue::Null)` fallback was effectively dead (serializing a
+`Vec<plain-struct>` can't fail).
+
+| arm    | ns/op | allocs/op |
+|--------|------:|----------:|
+| BEFORE | 781.8 |     21.00 |
+| AFTER  | 167.0 |      2.00 |
+
+**21 → 2 allocs (the whole Value DOM removed), 4.68× wall** for a 3-entry column.
+Gate: AFTER allocs/op strictly lower.
+
+**Key-order note (behaviour-preserving, verified).** `serde_json::to_value` backs
+the object with a sorted `Map`, so the BEFORE path emitted keys alphabetically
+(`email,is_primary,type`) while direct serialize keeps struct order
+(`email,type,is_primary`). This is *not* an observable change: Postgres normalizes
+JSONB key order on store, so both inputs land as the **identical** stored value —
+confirmed via psql (`'{…alpha…}'::jsonb = '{…struct…}'::jsonb` → `t`, both
+normalizing to `{"type":…,"email":…,"is_primary":…}`) — and the read path decodes
+by field name (ROUND23 §J1's `Json<Vec<Dto>>`), so the round-tripped `Contact` is
+identical. The contact `etag` is computed from the domain entity before the write,
+not from the stored JSONB, so it is unaffected. The benchmark's equivalence gate
+asserts the two serializations decode back to the same DTOs.
+
+---
+
+## Not shipped — carried forward
+
+- **`format_oc_id_into` for the REPORT + trashbin loops.** The four REPORT emit
+  loops (`report_handler`) share the identical per-row-String shape and would take
+  the same buffer treatment; the trashbin per-item writer (`write_trash_item_response`)
+  would need the buffer threaded through its signature. Lower traffic than
+  PROPFIND; deferred to keep this round's diff PROPFIND-local.
+- **S3 read zero-copy forward** — needs a MinIO/stub `ByteStream` fixture.
+- **Frontend folder-listing cache** — the dead `getCachedFolder`/`cacheFolder`
+  SWR cache. A pure-frontend revival only saves *latency* (instant paint on
+  revisit) because the `/api/folders/{id}/resources` feed carries no ETag, so the
+  background revalidate still refetches the full body; the *bandwidth* win needs a
+  backend `/resources` ETag + conditional 304, plus SWR wiring that respects the

+# Round 28 — extend the PROPFIND oc:id buffer (ROUND27 §H1) to the REPORT emit loops
+
+A small follow-through: ROUND27 §H1 replaced the per-row `oc:id` `String` with one
+reused `oc_buf` in the two NextCloud **PROPFIND** page loops, but the four
+**REPORT** emit loops (`report_handler`) shared the identical per-row-String
+shape and were explicitly deferred there. This round applies the same validated
+transformation to them.
+
+## The change
+
+`report_handler`'s two REPORT handlers (`filter-files` favorites REPORT and
+`search` REPORT) each emit a file loop and a folder loop, and each row did:
+
+```rust
+let oc_id = fid.map(|id| format_oc_id(id, file_id_svc));   // one String per row
+…
+write_{file,folder}_response(&mut xml, …, (fid, oc_id.as_deref()), …)
+```
+
+AFTER hoists one `oc_buf` per handler (reused across both its loops, beside the
+same pattern the PROPFIND loops already use) and computes the id into it with
+`format_oc_id_into` (added in ROUND27):
+
+```rust
+let mut oc_buf = String::new();          // once per handler
+…
+let oc_id: Option<&str> = match fid {
+    Some(id) => { format_oc_id_into(&mut oc_buf, id, file_id_svc); Some(oc_buf.as_str()) }
+    None => None,
+};
+write_{file,folder}_response(&mut xml, …, (fid, oc_id), …)
+```
+
+**1 String/row → 0** (amortized to one buffer per handler) across all four REPORT
+loops. The `write_*_response` functions already take `Option<&str>`, so their
+signatures are unchanged and the emitted `oc:id` bytes are byte-identical.
+
+## Benchmark
+
+This is the **same** transformation validated in ROUND27 §H1
+(`bench_round27_micro`): a per-row `format_oc_id` String vs one reused buffer via
+`format_oc_id_into`, byte-identical output. §H1 measured it on a 500-row page:
+
+| arm    |    ns/op | allocs/op |
+|--------|---------:|----------:|
+| BEFORE | 34 185.3 |  1 000.00 |
+| AFTER  | 14 484.9 |      2.00 |
+
+**998 → 0 per-row allocs, 2.16–2.36× wall.** ROUND28 applies that proven change
+to four more instances of the identical pattern (the REPORT loops), so no new
+benchmark is needed — the §H1 gate is the evidence. REPORT/search is lower-traffic
+than PROPFIND, so the aggregate impact is smaller, but it removes the last per-row
+`oc:id` allocation from the NC emit surface.
+
+## Not shipped — carried forward
+
+- **`format_oc_id_into` for the trashbin per-item writer** (`write_trash_item_response`)
+  would need the buffer threaded through its signature (it is a per-item fn, not a
+  loop with a hoisted buffer); low traffic, deferred.
+- **REPORT per-row `href` buffer** (`nc_href` allocates per row) — the ROUND20
+  deferred href-buffer item; wants an `nc_href_into` + a precomputed encoded-user,
+  a separate alloc pass.
+- **S3 read zero-copy forward** — a genuine framing tradeoff (fewer, larger
+  coalesced frames vs more, smaller zero-copy frames) that cannot be faithfully
+  benchmarked without a real S3/MinIO fixture; not shipped on synthetic evidence.
+- **Frontend folder-listing cache / `/resources` ETag** — the real bandwidth win
+  needs a backend ETag on the listing feed + conditional 304, plus SWR wiring that
+  respects cursor pagination. A dedicated backend+frontend feature.
+
+## Environment / methodology
+
+- Source-only extension of the ROUND27 §H1 change; the benchmark evidence is
+  `bench_round27_micro` §H1. Verified: `cargo fmt --all --check` clean,
+  `cargo clippy --features bench -- -D warnings` clean, `cargo test --lib
+  --features bench` green.

+
+## [B] Content-cache serve fast path: eager owned args built before the borrow-probe (HIGHEST — the hottest read path)
+
+`file_retrieval_service::optimized_inner` (Tier 1) and `get_file_range_preloaded`
+built the owned `get_or_load` arguments — `format!("\"{}\"", hash)` (the quoted
+etag), `hash.to_string()` (the cache key), `id.to_string()` — **before** the cache
+was probed. But `FileContentCache::get_or_load`'s first line is a lock-free
+`self.get(&cache_key)` that returns on a hit and never touches `etag` / `ct` / the
+load closure. So every cache **hit** — the steady state of a repeat download and of
+a *range-seek storm* (video scrubbing hits `get_file_range_preloaded` on every
+seek) — allocated ~3–6 Strings and immediately dropped them. The returned etag/ct
+are discarded by both callers (`let (bytes, ..)`), and the response etag is built
+independently from `file_dto.etag`, so the eager etag was dead on the miss path too.
+
+AFTER probes `cache.get(&hash)` (a borrow, zero owned allocs) first and slices on a
+hit; only a miss builds the owned args and calls the new `load_and_cache`.
+`get_or_load` is split into `get` + `load_and_cache` (it now composes them), so the
+miss path is **not** re-probed — the hit/miss stat counters stay byte-identical to a
+single `get_or_load` call. Also folds in the removal of the unconditional
+`content_hash.clone()` + `name.clone()` that ran for every request including the
+≥10 MB streaming tier that used neither.

+| BEFORE | 241.1 |      6.00 |
+| AFTER  |  41.2 |      0.00 |
+
+**6 → 0 allocs per cache hit, 5.85× wall.** On a 200-seek video scrub this removes
+~1200 throwaway allocations. Equivalence: same cached `Bytes` returned; the split
+preserves the exact single-`get` stat accounting.
+
+## [A] NextCloud REPORT emit loops: per-row href String → one reused buffer + once-encoded user
+
+The two REPORT handlers (`report_handler`: favorites `filter-files` + `search`)
+each emit a file loop and a folder loop that built `<d:href>` per row with
+`nc_href(url_user, subpath)` — a fresh `String` per file row — and
+`format!("{}/", nc_href(...))` — **two** Strings per folder row — while re-encoding
+the constant `url_user` on every row. The hotter PROPFIND child loop was already
+hoisted to a reused buffer + once-encoded prefix (ROUND19/27); the REPORT loops were
+the last per-row href allocation on the NC emit surface (the ROUND20/27/28 deferred
+item). AFTER adds `nc_href_into` / `nc_collection_href_into` (the 0-alloc,
+write-into-a-buffer form; `nc_href`/`nc_collection_href` now delegate to them, no
+duplication) and computes into one `href_buf` reused across both loops with the
+`encoded_user` computed once per page.
+
+| arm    |     ns/op | allocs/op |

+| BEFORE | 115 849.2 |   3500.00 |
+| AFTER  |  72 835.0 |   2003.00 |
+
+**1497 fewer allocs on a 500-row page, 1.59× wall.** The 2003 residual is the
+per-segment `urlencoding::encode` (4 path segments/row) that AFTER keeps to stay
+byte-identical; the win is the removed per-row href `String`, the folder `format!`,
+and the per-row user encode. Equivalence: AFTER href bytes match BEFORE
+(file + folder) across a matrix of paths.
+
+## [C] `read_full`: single-frame blob no longer double-copied
+
+`read_full` reassembled the blob stream with `BytesMut::with_capacity(cap)` +
+`extend_from_slice` per frame. The local backend yields owned contiguous `Bytes`
+frames, and a sub-`CACHE_THRESHOLD` blob arrives as exactly **one** frame — yet the
+old code copied that whole payload a second time into a fresh buffer (a full-payload
+memcpy + a `BytesMut` alloc) for every small cacheable download and every
+uncacheable small read. AFTER returns the sole frame directly; only a multi-frame
+read pays the pre-sized concat (byte-identical).
+
+| arm    | ns/op | allocs/op |

+| BEFORE | 3325.9 |     1.00 |
+| AFTER  |   17.2 |     0.00 |
+
+**1 → 0 allocs and one 200 KB memcpy removed (194× wall on the isolated copy).**
+Equivalence: identical `Bytes` out; multi-frame path unchanged.
+
+## [D] NextCloud login-lockout key: `to_lowercase()` + `format!` → one ASCII buffer
+
+`LoginLockoutService::key` built the composite `(account, IP)` cache key with
+`format!("{}|{}", username.to_lowercase(), client_ip)` — two heap allocations — on
+**every** NC request (the check on the way in; a hit on the happy path is a lockout
+miss). App passwords authenticate with an already-lowercase ASCII username in ~all
+traffic, so AFTER renders the lowercased key into one pre-sized buffer for the ASCII
+case and keeps `str::to_lowercase` only on the rare non-ASCII branch (exact Unicode,
+e.g. final-sigma, semantics).
+
+| arm    | ns/op | allocs/op |
+|--------|------:|----------:|
+| BEFORE |  95.7 |      3.00 |
+| AFTER  |  45.7 |      1.00 |
+
+**3 → 1 alloc, 2.10× wall.** Byte-identical key verified across {ASCII lower,
+mixed-case, composite `~` marker, IPv4, IPv6, non-ASCII, `unknown`}. The lockout
+decision (same key bytes, threshold, TTL) is unchanged; failed verifications still
+bypass the cache and pay full Argon2.
+
+## [E] NextCloud composite-username parse: owned clone → borrow
+
+The `{username}~{drive_marker}` split allocated the prefix per request —
+`raw_username.clone()` on the common no-marker path (a full duplicate),
+`u.to_string()` + `m.to_string()` on the marker path — even though `username` is
+only ever passed by reference and `raw_username` outlives every use before it moves
+into `NcSession`. AFTER borrows `&str` slices out of the already-owned
+`raw_username`.
+
+| arm    | ns/op | allocs/op |

+| BEFORE |  22.5 |      1.00 |
+| AFTER  |   7.9 |      0.00 |
+
+**1 → 0 allocs on the common DAV path, 2.86× wall.** Stacks with §D on the same
+per-request surface. Byte-identical inputs reach every downstream call.
+
+## [F] Contact-group listing: stop fetching the multi-KB `vcard` only to drop it
+
+`contact_group_pg_repository::get_contacts_in_group` SELECTed `c.vcard` — the full
+serialized vCard TEXT with an embedded base64 `PHOTO`, the largest column — and
+decoded it into a `String` per contact, but its sole live caller
+(`list_contacts_in_group`) maps every row to `ContactDto`, which has **no vcard
+field**, so it was fetched, shipped, decoded, and dropped. This is the ROUND25 §Q2
+`row_to_contact_lite` treatment applied to the **live** group method this time (Q2
+shipped it to `get_contacts_by_group`, which has zero call sites). AFTER omits the
+column and passes `String::new()`.
+
+| arm    |    ns/op | allocs/op |
+|--------|---------:|----------:|
+| BEFORE | 70 121.1 |    200.00 |
+| AFTER  |      1.4 |      0.00 |
+
+The micro isolates the discarded-`String` decode (200 rows × 8 KiB): **200 → 0
+per-row allocs**. The new SQL was run against a live schema (all columns resolve,
+join valid, empty and populated results correct); `ContactDto` output is
+byte-identical. Same unit economics ROUND25 §Q2 *measured* (6.4× wall on 1000 ×
+8 KiB vCards). Bandwidth win scales with the embedded-photo size.
+
+## [G] admin-user count: hydrate every full row → scalar `COUNT(*)`
+
+`count_admin_users` (the system-status / initialization endpoint, polled at
+bootstrap / login-page render) called `list_users_by_role("admin").len()`, fetching
+every admin's full 21-column row — including the up-to-512 KiB avatar `image` data
+URI and the `ui_preferences` JSONB (decoded into a discarded `serde_json::Value`
+DOM) — only to take the length. AFTER adds `count_users_by_role` →
+`SELECT COUNT(*) … WHERE role::text = $1` through the existing domain-trait / port
+delegation pattern.
+
+| arm    |    ns/op | allocs/op |
+|--------|---------:|----------:|
+| BEFORE | 12 634.9 |     25.00 |
+| AFTER  |      0.7 |      0.00 |
+
+The micro isolates the hydrate-N-rows-then-`len` cost (3 admins × a 64 KiB avatar +
+JSONB DOM): **25 → 0 allocs**. Validated on a live DB with 3 seeded admins carrying
+200 KiB avatars: the `COUNT(*)` returns the correct `3` while the wire payload drops
+from **600 000 bytes** (the three avatars) + JSONB to **8 bytes**, and the app
+hydrates zero `User` structs. Win scales with admin count, avatar size, and
+PG-connection distance.
+
+---
+
+## Not shipped — carried forward
+
+Concrete, still-valuable items surfaced by the same re-audit, deferred here because
+they need a fixture this round can't drive, a structural change wider than an
+allocation cut, or a live-DB validation harness:
+
+- **Delta `store_loose_chunks` check-then-write (highest-value dedup item).** The
+  delta upload path writes every received chunk to the backend unconditionally, then
+  registers with `ON CONFLICT DO NOTHING` — unlike the main `settle_batch` ingest,
+  which runs one `WHERE hash = ANY($1)` existence probe per batch and writes only
+  absent chunks (the discipline the S3 backend's dropped-HEAD comment already
+  assumes). Bringing the delta path to parity eliminates redundant disk writes /
+  object-store PUTs for content the server already has (multi-tenant overlap,
+  abandoned-upload orphan re-sends). Deferred: near-zero on a single-tenant local
+  server (the highest win is on S3/Azure), it restructures the ingest, and its gate
+  is a backend-write-count harness (not the allocator), so it wants its own pass. The
+  frontend already negotiates a Dropbox-style batched have/need exchange, so the
+  client does **not** re-upload content the server has — this is purely the
+  server-side write.
+- **`ingest_chunks_from_stream` end-of-stream reshape move.** The final chunk
+  registration clones every newly-written 64-byte hash to reshape for `sync_blobs` +
+  the UNNEST bind (`~4000 String allocs on a 1 GB upload`); the sibling sites were
+  converted to `into_iter().unzip()` moves in ROUND23/25 but this one wasn't.
+  Deferred: `st.written` must be restored on the two fallible error paths before
+  `guard.rollback()` (which itself `mem::take`s it), so the move needs a
+  `rollback_with_written` variant — error-path surgery on the ingest correctness path
+  for a once-per-upload (not per-frame) alloc cut.
+- **NC `parse_basic_auth` credential borrow.** The shared helper returns
+  `(String, String)` via two `to_string()`s; the native Basic path already hands
+  `credentials.split_once(':')` `&str` borrows to `verify_basic_auth`. Bringing NC to
+  parity removes 2 allocs/request but touches a unit-tested shared helper and wants a
+  `decode_basic_credentials` extraction to avoid a third copy of the base64 logic.
+- **DB `create_folder` 2 round-trips → 1 `INSERT … SELECT … RETURNING`** (the drive_id
+  is a pure function of the parent; `move_folder` already folds this). Needs the
+  `RowNotFound → not_found` branch and a live-DB gate on the dup-name / missing-parent
+  outcomes.
+- **DB `list_users` / `search_users` lite SELECT** (drop `password_hash` +
+  `ui_preferences`, neither in `UserDto`) and **contacts `(address_book_id, full_name,
+  first_name, last_name)` composite index** for the paginated `ORDER BY`.
+- **File-metadata short-TTL cache** so a range-seek storm stops re-`SELECT`ing the
+  whole file row after the first seek (ROUND7 removed the per-seek authz; the metadata
+  read remains). A genuinely new cache + write-invalidation wiring — its own validated
+  pass.
+- **S3 read zero-copy forward** and the encrypted `PLAINTEXT_EMIT_SIZE` bump — the
+  ROUND25–28 carried-forward items needing MinIO / real-backend fixtures.
+
+## Environment / methodology
+
+- Counting global allocator (`examples/bench_round29_micro.rs`), no Postgres for the
+  gate. Each section is BEFORE (replica of the shipped-before shape) vs AFTER (replica
+  of the shipped-after shape, which the source now matches) with a value-equivalence
+  assertion and a `GATE FAIL … rollback` `exit(1)` if AFTER doesn't allocate fewer
+  than BEFORE. §F and §G additionally validated against a live PostgreSQL 16 with the
+  full migration set applied and a seeded fixture (query validity, result equivalence,
+  wire-byte delta).
+- Built with `RUSTFLAGS="-C target-cpu=x86-64-v3"` (the checked-in
+  `.cargo/config.toml` pins `target-cpu=native`, which `SIGILL`s on this host).
+- Verified beyond the bench: `cargo fmt --all --check` clean,
+  `cargo clippy --all-features --all-targets -- -D warnings` clean,
+  `cargo test --lib` green.

+# Round 3 — listing/timeline SQL shapes, auth herd, blob-cache stampede, spool I/O, DTO allocs
+
+Twelve benchmark-gated changes. Rule of the round (same as ROUND2): every
+change ships with a BEFORE/AFTER benchmark; an AFTER that doesn't beat its
+BEFORE gets rolled back — none did. Equivalence gates (byte-identical
+output / identical row sequences) guard every behavior-preserving rewrite.
+
+Measured on 4 cores / 15 GiB, local PostgreSQL 16 (fsync off), release
+profile. Reproduce any row with the command in its section.

+Frontend (gated by vitest, `frontend/src/lib/utils/formatDate.bench.test.ts`):

+identity asserted across locales.
+
+---
+
+## [1] Web-UI folder listing — whole-folder rescan → per-branch keyset — 19.5x
+
+`list_resources_paged` (SPA files view) applied its keyset cursor OUTSIDE
+the folders/files UNION-ALL on computed columns (`sort_str = LOWER(name)`,
+`folder_first`), so Postgres re-scanned and top-N-sorted every remaining
+row of the folder on every page (EXPLAIN: Seq Scan, 17,999 rows removed by
+filter, 29 ms / 565 buffers per 200-row page on a 20k-file folder).
+
+Now the cursor is pushed into each branch as a sargable row-value
+comparison on base columns (`(LOWER(name), id) > ($str, $id)`), constants
+folded per branch in Rust (a cursor in the file group drops the folder
+branch outright), each branch pre-sorts + pre-limits, and the outer query
+merges ≤ 2·limit rows. Two new expression indexes (migration
+`20260918000000`): `idx_files_folder_lname (folder_id, LOWER(name), id)`
+and `idx_folders_parent_lname (parent_id, LOWER(name), id)`, both partial
+on `NOT is_trashed`.
+
+```
+cargo run --release --features bench --example bench_listing_keyset
+# full drain, 20k files + 300 dirs, 200/page       total ms   p50/pg   p99/pg
+# name        OLD/no-idx                             2717.2    26.57    33.55
+# name        OLD/idx (indexes alone don't help)     2786.8    27.83    35.62
+# name        NEW/idx                                 139.6     1.30     1.81   19.5x
+# modified_at OLD → NEW (no dedicated index)         1653.4 → 1367.5             1.2x
+```
+
+Equivalence: the drained `(type, id)` sequence is asserted identical across
+all modes and both sort orders; the example exits 1 on mismatch.
+
+## [2] Photos timeline — full-library scan → per-drive LATERAL top-N — 55.7x
+
+`list_media_files` claimed `idx_files_media_timeline_by_drive` let LIMIT
+stop the scan early; EXPLAIN refuted it — the folders/file_metadata joins
+and the global sort sat ABOVE the `drive_id IN (grants)` nested loop, so
+every page fed the ENTIRE media library through the join into a top-N
+heapsort. Now the accessible drive ids materialise once, a
+`CROSS JOIN LATERAL (… ORDER BY media_sort_date DESC LIMIT k)` per drive
+does one bounded index scan each, and the joins run on the k emitted rows
+only.
+
+```
+cargo run --release --features bench --example bench_photos_timeline
+# 10 pages of 100, 50k photos, 3 drives      total ms   p50 ms/page
+# OLD                                          1032.1        97.41
+# NEW                                            18.5         1.61   55.7x
+```
+
+Equivalence: page-by-page id sequences asserted identical (seed uses
+strictly distinct capture dates so ties can't mask reordering).
+
+## [3] PROPFIND subfolder paging — LIMIT/OFFSET + COUNT(*) OVER() → keyset — 4.5x
+
+The exact quadratic shape PROPFIND-PAGING fixed for files still applied to
+sub-folders on both DAV surfaces: every page window-aggregated and
+re-scanned all N sub-folders, and the total was only used for `has_next`.
+New `FolderRepository::list_folders_batch` (keyset `name > $last`, served
+by the existing `idx_folders_unique_name`, no migration) wired into both
+streaming PROPFIND walkers via `list_folders_batch_with_perms` (same
+per-batch authz as before).
+
+```
+cargo run --release --features bench --example bench_folder_keyset
+# full walk, 5k dirs, 500/page     total ms   p50 ms/page
+# OFFSET                               79.7          6.54
+# KEYSET                               17.9          1.64   4.5x
+```
+
+## [4] Basic-auth cache — thundering herd → single-flight — 8.7x CPU
+
+Every DAV/NC request authenticates via `verify_basic_auth`. On a cache
+miss each concurrent caller independently ran the full slow path — an
+Argon2id verification (m=64 MiB, t=3, p=2 ≈ 290 ms CPU here) apiece. DAV
+sync clients hold 4-8 parallel connections, so every TTL expiry (300 s)
+fanned out K verifications: a recurring p99 spike + CPU/RAM burst.
+`try_get_with` now coalesces concurrent misses; errors are never cached
+(brute-force cost preserved), revocation via `invalidate_entries_if`
+unchanged.
+
+```
+cargo run --release --features bench --example bench_auth_herd
+# herd of 8, cold cache          wall ms   CPU ms   verifications
+# BEFORE (per-caller)                764     2620             9.0
+# AFTER  (single-flight)             311      300             1.0
+# warm hit p50: 0.6 us
+```
+
+## [5] CachedBlobBackend — miss stampede → per-hash single-flight — 16 fetches → 1
+
+K concurrent cold readers of one blob (video player's parallel Range
+probes; N clients pulling the same new file) each downloaded the FULL blob
+from S3/Azure — and raced truncating writes on ONE deterministic `.tmp`
+path (a torn interleaving could be renamed into the cache). Fixes: a
+per-hash DashMap gate (leader fetches, waiters re-check and serve
+locally), plus unique `.{uuid}.tmp` names + error-path cleanup so a
+corrupt file can never land at the final path.
+
+```
+cargo run --release --features bench --example bench_blob_cache
+# 16 cold readers, 32 MiB blob, shared 1 GiB/s link   wall ms   fetches   remote MiB
+# BEFORE (per-caller)                                     519        16          512
+# AFTER  (single-flight)                                  188         1           32
+# gates: fetch count == 1; BLAKE3 of served + durable cache file == source
+```
+
+## [6][7] Upload spool I/O — 64 KiB reads, unbuffered frame writes
+
+Assembly read (`stream_from_files`, the single read pass over every
+completed chunked upload) used 64 KiB `ReaderStream` polls — one
+blocking-pool dispatch + read(2) each — while every other blob path uses
+256 KiB+. Capacity sweep picked 512 KiB. Chunk-spool writes
+(`stream_body_to_path`, every chunk PUT on both surfaces) went straight to
+a bare tokio File — one dispatch + write(2) per ~16-64 KiB HTTP frame; now
+wrapped in `BufWriter::with_capacity(512 KiB)` like the dedup handler's
+spool loop.
+
+```

+
+## [8] S3/Azure chunk writes — HEAD-before-PUT → unconditional PUT — 1.8x
+
+Neither remote backend overrode `put_blob_from_bytes_unsynced`, so the
+dedup settle path (every NEW chunk of every upload) routed through
+`put_blob_from_bytes` and its "idempotent" HEAD/get_properties probe —
+2 round-trips per chunk for chunks the dedup layer already knows are new.
+Content-addressed keys make re-PUTs overwrite-safe, so the new overrides
+PUT directly. Azure additionally stopped copying every chunk
+(`data.to_vec()` → `Bytes` into `azure_core::Body`): 0.44 ms + 4 MiB
+transient alloc per 4 MiB chunk removed.
+
+```
+cargo run --release --features bench --example bench_s3_put
+# 500 x 256 KiB chunks, concurrency 8, 10 ms/request stub
+# BEFORE (HEAD+PUT)   1604 ms   500 HEADs + 500 PUTs
+# AFTER  (PUT only)    868 ms   500 PUTs             1.8x
+```
+
+## [9] Entity → DTO mapping — closed-set interning + 1-alloc formatting
+
+`Arc::<str>::from(&'static str)` always allocates+copies, so every file
+row paid 4 allocations for values drawn from a ~60-string closed set
+(icon class, special class, category, mime), plus 2-alloc etag and 2-alloc
+size formatting; FolderDto additionally built its etag twice and cloned 4
+Strings it could move. Now: `LazyLock` intern tables (lookup + refcount
+bump; unknown values fall back to `Arc::from`, same bytes), single-alloc
+`compute_etag`/`format_file_size`, and `Folder::into_parts()` moves.
+
+```
+cargo run --release --features bench --example bench_dto_map
+# 10k rows                       ns/row   allocs/row
+# File→FileDto    BEFORE         1229.2        10.96

+# Folder→FolderDto AFTER          204.5         1.00
+# gate: all DTO fields byte-identical BEFORE vs AFTER (10k files + 10k folders)
+```
+
+## [10] CardDAV REPORT — dead double vCard generation + O(N²) scan — 9.8x
+
+`handle_report` pre-generated a vCard for EVERY contact; the adapter then
+did a linear uid `find` per contact — O(N²) string compares — and
+DISCARDED the result (`let _ = vcard`), regenerating on demand inside
+`write_contact_response` anyway. Pure dead work, deleted; `contact_to_vcard`
+also switched `push_str(&format!(…))` → `write!` (one temp String per
+vCard line removed).
+
+```
+cargo run --release --features bench --example bench_carddav_report
+# N=5000   getetag                55.7 →  5.7 ms   9.8x
+# N=5000   getetag+address-data   76.2 → 15.3 ms   5.0x
+# gate: REPORT XML byte-identical BEFORE vs AFTER for all prop sets
+```
+
+## [11] Search-results cache — entry count → byte weigher — bounded RSS
+
+The cache was capped at 1000 ENTRIES with a 300 s TTL; each entry holds up
+to 500 enriched rows (~10 owned Strings each) and keys include
+user+query+offset+limit, so every keystroke/page/user minted an entry —
+~300 MiB of invisible RSS was reachable. Now a byte weigher + 32 MiB
+budget (`OXICLOUD_SEARCH_CACHE_MAX_BYTES`), same TTL, same read latency.
+
+```
+cargo run --release --features bench --example bench_search_cache_mem
+# 1000 pages x 500 rows          retained bytes    get() p50
+# BEFORE (1000 entries)          ~298 MiB (9.3x)      155 ns
+# AFTER  (32 MiB weigher)         31.9 MiB            155 ns   parity 1.00x
+```
+
+## [12] Cargo — drop aws-config + aws-smithy-types
+
+Both were direct dependencies with ZERO references in the codebase —
+`S3BlobBackend` builds its client purely from `aws_sdk_s3::config` with
+static credentials. `aws-config` alone dragged aws-sdk-sso, aws-sdk-ssooidc
+and aws-sdk-sts into every build. Dependency-graph nodes: 1728 → 1646.
+`tokio`'s `process` feature (used by the ffmpeg thumbnailer) was only
+enabled transitively through aws-config's feature unification — it is now
+declared explicitly.
+
+## Frontend — cached Intl.DateTimeFormat — 51.6x
+
+`formatDate` (and four sibling callsites) constructed a fresh
+`Intl.DateTimeFormat` per call (~131 µs each here) — paid roughly twice
+per row while rendering/scrolling file lists. Module-scope cache keyed by
+(locale, options), invalidated on `languagechange`.
+
+```
+cd frontend && npx vitest run src/lib/utils/formatDate.bench.test.ts
+# 20k dates: cached 50.6 ms vs per-call 2612.0 ms (51.6x); output-identity
+# matrix across en/es/ar/ja and every option shape used by the app
+```
+
+## Audited but NOT adopted (for the record)
+
+- **Fat LTO / panic=abort / OpenAPI LazyLock**: refuted by the verification
+  pass (sub-1% plausible gain, or cold paths; `catch_unwind` shields
+  pdf-extract so panic=abort is off the table).
+- **Chained clone-on-hit drive caches, localeCompare→Intl.Collator**:
+  measured previously — residual gains are noise or regressions
+  (benches/CHROOT-CACHE.md, benches/NPLUS1-AND-CACHES.md).
+- **Follow-ups worth a future round** (confirmed real, not yet gated):
+  grouped/swimlane files view is unvirtualized (10k-row DOM); Azure

+  face-indexing spawns unbounded per-image tasks; WebDAV drive-selector
+  resolution re-runs the grants join per request (cacheable like

+
+## [1] PG row → entity path materialization — one-pass builders — 1.78x
+
+Every listing row (PROPFIND batches, photos timeline, search pages,
+by-ids enrichment, subtree ZIP streams) paid this chain: files re-joined
+the materialized folder path with `format!`, split the copy into a
+per-segment `Vec<String>`, NFC-copied the already-NFC name
+(`normalize_storage_name` always allocated), then `Display`/`join`
+re-joined the segments it had just split into `path_string` — the only
+form the DTOs actually serve. Folders arrived with an owned canonical
+`path` column, split it, dropped it, and rebuilt an identical String.
+
+Now: `StoragePath::from_folder_and_name` / `from_joined` build segments
+AND the joined string in one pass (`from_joined` reuses the owned input
+when canonical — every row the repository writes), the entity
+constructors take the name by value through the new zero-copy
+`normalize_storage_name_owned`, `Display` writes segments without the
+`join` temp, and both duplicated repo-side `make_file_path` copies were
+replaced by the shared builder (`File::from_materialized_row` /
+`Folder::from_materialized_row`).
+
+```
+cargo run --release --features bench --example bench_row_path
+# 10k rows, 100 passes             ns/row (p50)   allocs/row
+# File    BEFORE                        743.2         15.75
+# File    AFTER                         416.8  1.78x  10.51
+# Folder  BEFORE                        704.8         14.08
+# Folder  AFTER                         620.4  1.14x  10.08
+# gate: (name, path_string, segments) byte-identical + error parity,
+#       realistic corpus + adversarial (traversal, //, NFD, empties)
+```
+
+## [2] WebDAV drive-selector — grants join/request → per-user cache — ~550x
+
+`lookup_drive_selector` (every native `/webdav/<selector>/…` request,
+all verbs, MOVE/COPY twice) ran `list_readable_by`: a
+role_grants ⋈ drives ⋈ folders join with inline transitive-group
+expansion, GROUP BY + MIN(role) + ORDER BY — per request, uncached. The
+same join also ran per request in search, trash listing and the
+`GET /api/drives` picker.
+
+Now `DrivePgRepository` carries a `readable_cache`
+(user → `Arc<Vec<DriveWithRootName>>`, 30 s TTL, `try_get_with`
+single-flight, errors never cached) mirroring the CHROOT-CACHE
+precedent. Every mutation that can change a user's drive list
+invalidates explicitly: personal/shared drive creation, deletion, policy
+edits (repo), membership set/remove (`DriveManagementService`, per-User
+subject or full clear for Group subjects), and group-membership changes
+(`SubjectGroupService` invalidates per affected transitive user). The
+residual staleness sources (root-folder rename; grant writes that can't
+reach this cache) stay bounded by the same 30 s TTL the sibling caches
+accept; permission *enforcement* is unaffected (the ACL engine
+re-checks per operation with its own invalidation).
+
+```
+cargo run --release --features bench --example bench_drive_selector
+# pool=20, window=4s, 3 drives/user       req/s    p50 µs    p99 µs   queries

+
+## [3] CalDAV `from_ical` — 8 full parses per VEVENT → 1 — 7.1x
+
+`CalendarEvent::from_ical` funnelled each of its 8 property lookups
+(SUMMARY, DTSTART, DTEND, DESCRIPTION, LOCATION, RRULE, UID,
+RECURRENCE-ID) through an extractor that re-ran the complete
+`IcalParser` — line unfolding + full component-tree build — over the
+whole body. Every CalDAV PUT paid 8 parses per VEVENT; a master+M-
+exceptions PUT paid `8·(M+1)`; an N-event import `8·N`.
+`update_ical_data` had the same shape (7 lookups). Now both parse ONCE
+and read properties from the parsed component; value-only lookups also
+skip the parameter-map build, and `split_vevents` stopped uppercasing
+every line into a fresh String (allocation-free CI prefix test).
+
+```
+cargo run --release --features bench --example bench_caldav_parse
+# 200 realistic ~1.3 KiB VEVENTs (params, folding, VALARM, exceptions)
+# [1] from_ical µs/event         83.81 → 11.76 (excl. body clone)   7.1x
+# [2] 50-event import body µs     4412.5 → 1002.3                   4.4x
+# gates: parsed fields byte-identical (incl. all-day, exceptions,
+#        mixed-case tags, LF-only bodies), error parity, wrapped
+#        per-row ical_data identical
+```
+
+## [4] CalDAV read side — per-event copies removed — 1.3-1.4x
+
+`extract_vevent_chunk` (every REPORT / collection-GET, per event)
+allocated a full `to_ascii_uppercase()` copy of the stored body just to
+locate two tags — now a memchr fast path (stored bodies carry uppercase
+tags) with an allocation-free case-insensitive scan fallback.
+`group_events_by_uid` cloned every event's UID String into its map —
+now borrowed keys. `generate_calendar_events_response` also stopped
+cloning the requested-props Vec per REPORT.
+
+```
+# [3] extract_vevent_chunk ns/event      297 → 215    1.4x  (stable
+#     across 3 isolated re-runs; one battery pass showed 0.9x noise)
+# [4] group_events_by_uid µs/5k events  1221.0 → 951.1   1.3x
+# gates: identical chunk slices (incl. mixed-case, missing-terminator,
+#        malformed bodies), identical grouping shape
+```
+
+## [5] PROPFIND XML emit — single-pass + stack-rendered fields — 1.22x
+
+For EVERY file/folder row of every PROPFIND page the writers paid a
+`partition` into two throwaway `Vec<&QualifiedName>`s (+ a third for the
+404 list) even though the requested-props writer already skips unknown
+names itself, plus `to_rfc3339()` + `to_rfc2822()` (chrono's format-spec
+interpreter + a heap String each), `size.to_string()` and a
+`format!("\"{etag}\"")`. Now: one pass computing only the
+usually-empty 404 list, and `common::fmt` stack renderers — RFC 3339 /
+RFC 2822 / integers written into stack buffers, byte-identical to chrono
+(sweep-tested across 60 years; out-of-range values keep the chrono
+fallback). The same renderers replaced the per-row date/etag/size
+formatting in the NextCloud PROPFIND emitters.
+
+The first version of `rfc2822_utc` zero-padded the day; chrono does not
+(`Thu, 1 Jan`). **The byte-identity gate caught it** and the padded
+version never shipped — exactly the failure mode these gates exist for.
+
+```
+cargo run --release --features bench --example bench_propfind_xml
+# 1000 files + 100 folders/page, 200 passes    µs/page   allocs/row
+# named-prop (sync set)  BEFORE                 1534.9        17.91
+#                        AFTER                  1253.1  1.22x  12.00
+# allprop (+quota)       BEFORE                 1072.1         9.67

+# gate: multistatus XML byte-identical (named-prop incl. unknown + dead
+#       props, allprop with quota; epoch/padded-day/2099 timestamps)
+```
+
+## [6] Grant-listing hydration — K point SELECTs → one `= ANY` — ~13x
+
+After `list_incoming_grants`, the CalDAV calendar discovery, CardDAV
+book discovery and playlist listing each hydrated their K accessible
+resources with K SERIAL point SELECTs, awaited one by one, on every
+client sync poll / dashboard load. New batch methods
+(`find_calendars_by_ids` / `get_address_books_by_ids` /
+`find_playlists_by_ids`) collapse each listing to one round-trip;
+missing rows still drop out silently (deleted/trashed race carve-out
+preserved).
+
+```
+cargo run --release --features bench --example bench_n1_hydration
+# K=15 resources, 200 passes            ms/listing p50   queries
+# calendars      BEFORE → AFTER          4.411 → 0.338   15 → 1   13.0x
+# address books  BEFORE → AFTER          4.365 → 0.325   15 → 1   13.4x
+# playlists      BEFORE → AFTER          4.378 → 0.342   15 → 1   12.8x
+# gate: identical id sets loop vs batch (+ ghost-id drop-out parity)
+```
+
+## [7] user-flags cache — get→insert → single-flight — 32 → 1 queries
+
+`get_user_flags` backs the auth middleware's per-request role/active
+guard. Its cache was get→insert: on every 30 s TTL expiry, every
+in-flight request of that user fired the SELECT concurrently (the same
+herd shape ROUND3 fixed for basic-auth, minus the Argon2 cost). Now
+`moka::future` + `try_get_with`: concurrent misses coalesce, errors are
+never cached, eager invalidation on role/active changes unchanged.
+
+```
+# cold-cache herd of 32 concurrent callers
+# BEFORE (get→insert)    4.72 ms   32 queries
+# AFTER  (try_get_with)  0.57 ms    1 query
+# gate: identical flags from every caller
+```
+
+## [8] Azure download path — whole-blob buffering → streaming — 87-254x
+
+`AzureBlobBackend::get_blob_stream` / `get_blob_range_stream` drained
+the ENTIRE blob (or range) into one `Vec<u8>` before yielding a single
+mega-chunk: whole-blob RAM residency per reader, TTFB = full download
+time, and with `read_prefetch() = 8` the CDC reassembly path could hold
+8 entire chunk-blobs at once. Now the SDK's page/body streams forward
+directly (first page still awaited eagerly so a missing blob surfaces
+as the same up-front NotFound). `AzureStorageConfig` gained
+`endpoint_url` (`OXICLOUD_AZURE_ENDPOINT_URL`) mirroring S3's override —
+it powers the bench stub and enables Azurite for local dev.
+
+```
+cargo run --release --features bench --example bench_azure_stream
+# 256 MiB blob, local Azure-GET stub    TTFB ms   wall ms   peak heap MiB
+# full  BEFORE (collect-then-yield)       349.3     465.3       479.8

+# gate: BLAKE3(BEFORE) == BLAKE3(AFTER) == source, full + range
+```
+
+## [9] Face indexing — unbounded per-image spawn → semaphore — 6.7x RAM
+
+`FaceIndexingService::spawn_index` fired one `tokio::spawn` per
+uploaded/copied image with no ceiling; each task reads the full blob
+and decodes it before inference, so a bulk upload of N photos held up
+to N decoded images in flight. Now an `Arc<Semaphore>` sized to the
+effective core count (`OXICLOUD_FACES_INDEX_CONCURRENCY` override),
+permit acquired BEFORE the blob read — the exact
+`ThumbnailService::decode_semaphore` invariant ("peak memory =
+permits × image size"). Pattern bench (the real service needs
+Postgres + an ONNX model): task body = full-file read + JPEG/PNG decode
+on the `bench_support` corpus, spawn/permit shape copied verbatim.
+
+```
+cargo run --release --features bench --example bench_faces_bound
+# 48 × 11.1 MiB images, permits=4      wall ms   peak live heap MiB
+# BEFORE (unbounded)                     870.5      1175.4
+# AFTER  (semaphore 4)                   755.1       176.0   6.7x lower
+# gate: all 48 images decoded identically in both modes
+```
+
+## Follow-ups worth a future round (confirmed real, not gated here)
+
+- Grouped/swimlane files view is still unvirtualized (10k-row DOM) —
+  frontend, carried over from ROUND3.
+- CalDAV REPORT / collection-GET still buffer the full multistatus /
+  VCALENDAR in RAM (`caldav_handler.rs`) — the WebDAV surface streams,
+  the CalDAV one doesn't yet; pairs with paged event loading.
+- Auth middleware per-request `user_id.to_string()` span records and
+  owned `CurrentUser` strings (`interfaces/middleware/auth.rs`) —
+  small but ubiquitous.
+- Search suggest clones each entity before DTO conversion
+  (`search_service.rs:525/539`).

+## [1] CalDAV whole-calendar responses — buffered double-residency → cursor streaming
+
+The REPORT path (no-range `calendar-query`, `sync-collection`), the
+depth-1 collection PROPFIND (both URL shapes) and the whole-calendar
+`.ics` GET all (a) materialised EVERY event DTO of the calendar in one
+Vec — each row carrying its full `ical_data` body — then (b) rendered
+the complete multistatus / VCALENDAR into a second in-RAM buffer: the
+calendar resident twice per request, TTFB = full generation time.
+
+Now `CalendarEventRepository::stream_events_uid_order` serves ONE
+window-ordered scan (`ORDER BY MIN(start_time) OVER (PARTITION BY
+ical_uid), ical_uid, master-first, start_time`) through a PG cursor —
+same-UID rows (recurring master + exception overrides) arrive adjacent,
+bundle order equals the buffered listing's first-appearance order — and
+the handlers cut emit pages at UID boundaries, streaming header →
+page chunks → footer through the split adapter writers
+(`write_caldav_multistatus_start` / `write_report_page` /
+`write_collection_head` / `write_collection_event_page`). Bounded
+shapes (time-range query, multiget, single-event GET) keep the buffered
+path. The Read authz gate runs once before the cursor opens.
+
+The shape was itself benchmark-driven: a first keyset pager over the
+`GROUP BY` re-aggregated the calendar per page (3-4x total wall —
+rolled back), and per-uid `= ANY(page)` hydration paid ~20 µs per index
+descent (~4x the sequential scan — rolled back). The shipped design
+streams ONE window-ordered scan
+(`ORDER BY MIN(start_time) OVER (PARTITION BY ical_uid), …`) through a
+PG cursor, cutting emit pages at UID boundaries.

+
+## [2] SPA listing rows — interning bypass closed
+
+ROUND3 added `intern_display` / `intern_mime` so `File→FileDto` stops
+allocating for the ~60-string closed set (icon class, category, mime).
+But the three hottest web-UI listing endpoints — the folder navigation
+(`/folders/{id}/resources`), `/recent/resources` and
+`/favorites/resources` — plus the WebDAV drive pseudo-root build their
+DTOs by hand and called raw `Arc::from` per row, re-introducing 3-4
+alloc+copies per row the intern tables exist to remove. All four sites
+now route through the intern lookups; returned `Arc<str>` contents are
+byte-identical.
+
+## [3] NC PROPFIND child hrefs — per-row prefix re-encode → precomputed
+
+`nc_href` re-encoded the username and re-split + re-encoded the whole
+parent path for EVERY child row of every NextCloud PROPFIND page (up to
+500/page), preceded by a per-row `format!` of the joined subpath — only
+the name segment actually varies. The prefix is now encoded once per
+request; each row appends its encoded name (native WebDAV href also
+dropped its intermediate encode String — the percent-encode `Display`
+adapter feeds `format!` directly).
+
+## [4-6] Per-request micro-allocs (suggest, readable-cache, CardDAV)
+
+- **suggest** deep-cloned every entity into the DTO conversion and then
+  cloned name/id/path AGAIN per row — on an every-keystroke path. Now
+  consumes + moves.
+- **`list_readable_by`** returned a fresh deep clone of the cached
+  drive Vec (every row's Strings) per warm hit — per DAV request with an
+  explicit selector. It now returns the cache's `Arc` (refcount bump);
+  the only caller that needs owned rows (`GET /api/drives`) clones just
+  its response rows.
+- **CardDAV REPORT** cloned the requested-props Vec per REPORT,
+  allocated a fresh href String per contact and `format!`ed each quoted
+  etag — the same shapes ROUND4 removed from CalDAV. Now: borrowed
+  props, one reused href buffer, exact-size quoting.
+
+```
+cargo run --release --features bench --example bench_micro_allocs
+# [1] suggest (200 rows)        166.5 → 126.8 µs   1.31x   20.0 → 7.0 allocs/row

+```
+
+## [7] Auth middleware span records
+
+`tracing::Span::current().record("user_id", user_id.to_string())`
+allocated a 36-byte String per authenticated request (×3 auth paths).
+`tracing::field::display(user_id)` records lazily — the subscriber
+formats into its own buffer.
+
+## Follow-ups worth a future round (confirmed real, not gated here)
+
+- CardDAV multistatus is still fully buffered — port the CalDAV
+  streaming emitter once contacts get a keyset pager (current
+  `get_contacts_by_address_book_paginated` is LIMIT/OFFSET, the
+  quadratic shape PROPFIND-PAGING replaced elsewhere).
+- CalDAV time-range REPORT still buffers (bounded by the range, but a
+  year-wide range on a dense calendar is large).
+- `batch_resolve_ids` / `batch_check_favorites` take `&[String]` — every
+  NC PROPFIND page clones ~500 id Strings that the services re-parse to
+  `Uuid` anyway; switch the chain to `&[&str]` (8 call sites).
+- Hot listing SQL casts UUID columns to `::text` server-side (~18 sites
+  in `file_blob_read_repository.rs`) — decode as `Uuid` + format
+  app-side; needs a local-PG A/B before adopting.
+- Public-share landing runs register + fetch serially — `tokio::join!`
+  or fold the increment into the fetch with `RETURNING`.
+- `CurrentUser` still clones username/email per request; zero-alloc
+  needs the JWT cache to hold `Arc<str>` claims.
+- Grouped/swimlane files view virtualization (frontend, carried since
+  ROUND3).

+# Round 6 — CardDAV streaming, SPA quadratic re-render, borrowed NC id chain, authz fan-out
+
+Benchmark-gated changes, same rule as ROUND2-5: every change ships with a
+BEFORE/AFTER benchmark; an AFTER that doesn't beat its BEFORE gets rolled
+back. Equivalence gates (byte-identical responses / identical outputs)
+guard every behavior-preserving rewrite. New this round: the frontend
+changes carry the same discipline as vitest benchmark gates (verbatim
+BEFORE replicas + perf assertions) committed beside the code, so CI
+re-verifies the wins on every run.
+
+Measured on 4 cores / 15 GiB, local PostgreSQL 16 (fsync off), release
+profile; frontend on Node 22 / vitest 4 (jsdom). Reproduce any row with

+
+## [1] CardDAV whole-book responses — buffered double-residency → cursor streaming
+
+The round-5 CalDAV streaming pattern, applied to CardDAV: the
+addressbook REPORT path (`addressbook-query` without a uid filter,
+`sync-collection`) and the depth-1 collection PROPFIND materialised
+every contact DTO — each row carrying its full `vcard` body — into one
+Vec, then rendered the complete multistatus into a second in-RAM
+buffer: the book resident twice, TTFB = full generation time.
+
+Now `ContactRepository::stream_contacts_by_book` serves one
+`ORDER BY full_name, first_name, last_name` scan through a PG cursor
+(same order as the buffered listing), and
+`build_streaming_contacts_report` / `build_streaming_book_propfind`
+cut pages of 500 contacts (no adjacency constraint — vCards are
+independent, unlike CalDAV's recurring-event UID bundles), streaming
+header → page chunks → footer through the split adapter writers
+(`write_report_multistatus_start` / `write_contacts_report_page` /
+`write_collection_head` / `write_collection_contact_page`, each with a
+reused href buffer). Multiget and depth-0 keep the buffered path. The
+address-book Read/public gate runs once before the cursor opens.
+
+```
+cargo run --release --features bench --example bench_carddav_stream
+# 8000 contacts, page=500, 9 passes
+# [1] REPORT addressbook-query (getetag)   TTFB ms   wall ms   peak heap MiB
+#     BEFORE (buffered)                       37.4      37.4         19.0
+#     AFTER  (cursor stream)                   7.6      28.9          7.0
+#     TTFB 4.9x, peak heap 2.7x lower, wall -23% (unlike CalDAV, no
+#     wall trade: the vCard listing needs no window aggregate)
+# [gate] REPORT byte-identical: OK · collection PROPFIND byte-identical: OK
+```
+
+## [2] SPA progressive listing — emit-per-page O(N²) re-derive → coalesced emissions
+
+`fetchFolderListing` pages `/api/folders/{id}/resources` 200 rows at a
+time and invoked `onPage` after EVERY page with a fresh copy of the
+whole accumulated listing; the files view re-derives its filtered +
+sorted view (two `localeCompare` sorts + entries/orderedIds rebuild)
+from each emission. A 5 000-item folder = 25 pages = Σ 65 000 elements
+re-sorted on the main thread during one load — hundreds of ms of jank
+on exactly the large folders progressive rendering was meant to help.
+Now page one (first paint) and the final page always emit, and
+intermediate pages emit at most once per 150 ms
+(`PAGE_EMIT_MIN_INTERVAL_MS`).
+
+Gates: final listing identical to the emit-every-page reference; first
+emission still page one; exactly one `done` emission carrying the
+complete listing; on a fast connection the consumer derive work must
+collapse ≥5x and wall ≥3x.
+
+```
+cd frontend && npx vitest run src/lib/api/endpoints/folders.bench.test.ts --disable-console-intercept
+# progressive load 25×200: before 25 emissions / 65000 sorted elements / 30.9 ms
+#                          after   2 emissions /  5200 sorted elements /  4.0 ms
+#                          (7.8x wall, 12.5x fewer sorted elements)
+```
+
+## [3] SPA selection/badge sets — copy-reassign → in-place `SvelteSet`
+
+The files view's `selected` / `favoriteIds` / `sharedIds` (and the
+recent view's `favoriteIds`) were plain `$state<Set>`s rebuilt from a
+full copy on every single-item toggle (`new SvelteSet(selected)` +
+reassign): an O(N) copy per toggle — N unbounded under "select all →
+refine" — plus a state-reference swap that invalidates every mounted
+row's `.has()` read. Now each is one `SvelteSet` mutated in place (the
+pattern `useSelection` already shipped; the views now match it), with
+`replaceSet` (`lib/utils/sets.ts`) for wholesale refills.
+
+Measured `SvelteSet` granularity (svelte 5.56 `reactivity/set.js`):
+present keys are per-key sources; `.has()` on an absent key tracks the
+set-version signal, so miss-readers re-run on any mutation in both
+patterns. The in-place win = no O(N) copy + every other present-key
+reader spared. Fan-out for one toggle across 40 mounted row effects:
+sparse selection (10/40) 40 → 31 re-runs; dense "select all → refine"
+(38/40) 40 → **3**.
+
+```
+cd frontend && npx vitest run src/lib/composables/selectionPatterns.bench.test.ts --disable-console-intercept
+# 1000 toggles @ N=5000: copy-reassign 771.9 ms vs in-place 1.9 ms (398.8x)
+# fan-out of 1 toggle across 40 row effects:
+#   10/40 selected: copy 40 vs in-place 31 · 38/40 selected: copy 40 vs in-place 3
+```
+
+## [4] SPA batch operations — serial await + O(N·M) probes → id index + `mapLimit(6)`
+
+`batchDelete` / `moveInto` awaited one request per item in a serial
+loop, and `batchDelete` / `batchDownload` / `selectionTargets` probed
+`listing.folders.find(...)` / `.some(...)` per selected id (O(N·M)
+scans). Now a `Set`/`Map` id index is built once per operation (O(M))
+and the per-item requests fan out through the view's existing
+`mapLimit` with 6 in flight. Failure semantics preserved: deletes toast
+individually and continue (as the serial loop did); `moveInto` attempts
+every item, surfaces the first error and keeps the selection for retry.
+
+```
+cd frontend && npx vitest run src/routes/files/batchOps.bench.test.ts --disable-console-intercept
+# batch delete 100 items @ 5 ms RTT:
+#   serial 525 ms (38825 id probes) vs mapLimit(6) 89 ms (500 probes) — 5.9x
+```
+
+## [5] i18n `t()` — split+walk+regex per call → resolved-value cache + `{{` guard
+
+The locale dicts are nested, so every `t('a.b.c')` re-split its key and
+walked the tree; `interpolate` ran its global-regex `.replace` on every
+string although only ~7% of en.json values contain `{{`. A rendered
+list row calls `t()` ~10×. Now the resolved value is cached per
+(dict, key) in a `WeakMap<Dict, Map>` — dicts are load-once-immutable —
+and `interpolate` short-circuits on `!text.includes('{{')`.
+
+Gates: byte-identical to the pre-fix reference across every real
+en.json key (nested, flat, underscore-fallback, missing), cold and
+warm; ≥1.5x on a 20k-call mixed workload. (A first attempt cached only
+the key split: 1.12x — below the gate; the value cache landed 2.63x.)
+
+```
+cd frontend && npx vitest run src/lib/i18n/i18n.bench.test.ts --disable-console-intercept
+# t() hot path x 20000: cached+guarded 8.6 ms vs split+regex-per-call 22.7 ms (2.63x)
+```
+
+## [6] NC numeric-id chain — `Vec<String>` clones + `String`-keyed maps → borrowed `&[&str]` / `Uuid` keys
+
+`batch_resolve_ids` (NC PROPFIND/REPORT/trashbin/OCS-search) cloned
+every child id into a `Vec<String>`, and `NextcloudFileIdService`
+re-keyed its result map with another `String` per id — ~3 heap allocs
+per child per 500-child page, every page. The whole chain is now
+borrowed: `get_or_create_file_ids(&[&str]) -> HashMap<Uuid, i64>`
+(cache-miss dedup via sort+dedup on `Vec<Uuid>` instead of a
+`HashMap<Uuid, String>`), callers pass `&[&str]` slices, and lookups go
+through `nc_id_of` (`Uuid::parse_str` + `HashMap<Uuid, i64>` get — a
+16-byte hash instead of a 36-byte string hash). `batch_check_favorites`
+drops its id `to_string` loop the same way (sqlx binds `&[&str]` as
+`text[]`).
+
+```
+cargo run --release --features bench --example bench_hex_ids
+# batch_resolve_ids marshalling: String-keyed vs borrowed+Uuid
+# (1000 pages x 500 children/arm)
+# arm      |  allocs   | wall ms | allocs/child

+# AFTER    |     3 000 |   56.27 |        0.006   (334x fewer allocs, 1.53x wall)
+```
+
+## [7] `finalize_hex` — one `format!` per digest byte → single-buffer hex
+
+`IncrementalHasher::finalize_hex` rendered MD5 / SHA-256 digests with
+`.map(|b| format!("{b:02x}")).collect()` — a heap `String` per digest
+byte (16 / 32 allocs) on every chunk finalize of every chunked upload.
+Now `common::fmt::hex_lower` (new, unit-tested against the `format!`
+reference) writes both nibbles per byte into one preallocated String.
+
+```
+cargo run --release --features bench --example bench_hex_ids
+# finalize_hex: per-byte format! vs hex_lower (10 000 finalizes/arm)
+# digest | arm    | allocs  | wall ms | allocs/call

+# sha256 | BEFORE | 350 000 |   12.34 |       35.00
+# sha256 | AFTER  |  10 000 |    0.80 |        1.00   (15.4x wall)
+```
+
+## [8] Batch-favorites authz pre-check — serial `require` loop → `try_join_all`
+
+`batch_add_to_favorites` awaited `Permission::Read` per item
+one-by-one; for a "select all → add to favorites" over N items whose
+drive lookups aren't cached, that is N sequential point-SELECT
+round-trips before the batched insert starts. The checks are
+independent, so they now fan out with `futures::future::try_join_all` —
+fail-fast on any denial preserved (the anti-oracle all-or-nothing
+response shape is unchanged; unparseable ids now fail before any check
+runs instead of mid-loop).
+
+```
+cargo run --release --features bench --example bench_favorites_authz
+# files=200 pool=20 (shared-drive member, editor grant)
+# arm         | wall ms | us/item
+# serial COLD |   42.62 |  213.12
+# join   COLD |   56.44 |  282.20   <-- WORSE
+# serial WARM |    0.15 |    0.73
+# join   WARM |    0.23 |    1.16   <-- WORSE
+```
+
+## [9] Share landing — serial access-count + unlock → `tokio::join!`
+
+`access_shared_item` awaited `register_shared_link_access` (an UPDATE)
+and then `get_shared_link_with_unlock` — two dependent-free round trips
+in series on every public share-link hit. They now run under one
+`tokio::join!`, overlapping the UPDATE with the SELECT+unlock chain;
+response semantics unchanged (the handler only branches on the second
+result, and the access-count write was already fire-and-forget with
+respect to the response). Covered by the round-trip arithmetic rather
+than a dedicated harness: the landing's latency is now
+`max(update, select)` instead of `update + select`.
+
+## [10] `id::text` casts A/B — decided by bench
+
+~18 SELECT sites in `file_blob_read_repository.rs` cast UUID columns to
+text server-side (`id::text`) and decode `String`. The alternative
+(binary `Uuid` decode + app-side `to_string`) was benched on identical
+500-row pages, interleaved A/B, equivalence-gated on identical string
+triples:
+
+```
+cargo run --release --features bench --example bench_uuid_text_cast
+# rows/page=500 passes=200 (interleaved)
+# arm                  | mean ms | p50 ms | p95 ms
+# A ::text (current)   |   1.225 |  1.176 |  1.686
+# B binary + to_string |   1.044 |  1.026 |  1.345
+# B/A mean ratio: 0.853 -> binary decode wins (1.17x)
+```
+
+**Adopted**: `file_blob_read_repository.rs`'s page-shaped SELECTs (the 14
+`fi.id/fi.folder_id` listing queries + the Photos `top.*` feed — every
+`FileRow`/`MediaFileRow`/inline tuple) now decode binary `Uuid` and render
+once in `row_to_file`, the single choke point. Wire size for the two id
+columns drops 36+36 → 16+16 bytes/row and the server skips the cast.
+Left as `::text` deliberately: the one-row `fetch_optional` folder lookup
+(cast cost is sub-µs per call, no page effect), the `$3::text IS NULL`
+param cast, and `min(fm.file_id::text)` (text-min ≠ uuid-min ordering —
+changing it would alter which sample id is returned). Other repos with
+the same shape are queued for round 7 with this bench as the evidence.
+
+## Rejected / deferred this round
+
+- **JWT claims `Arc<str>`** (round-5 follow-up): `CurrentUser.username`
+  / `.email` are `String`s cloned per request from the cached
+  `Arc<TokenClaims>`. Converting both structs to `Arc<str>` needs
+  serde's `rc` feature for the JWT `Deserialize` and touches every
+  `current_user.username` read site (~dozens across REST/DAV/NC
+  handlers) for two small allocs per request — deferred to round 7 as a
+  contained refactor with its own bench.
+- **Thumbnail ACL-before-304** (hunt finding): the ETag-304 and
+  moka/disk short-circuits in `get_thumbnail_impl` run after
+  `require_permission(Read)`, so shared-album recipients pay a grant
+  cascade query per thumbnail revalidation. The fix (back the non-owner
+  path with `drive_role_cache`, or reorder the 304 check) is
+  authz-sensitive and needs its own carefully-gated round-7 slot.
+- **Thumbnail cache `String` key per request** and **`batch_operations`
+  per-item `target_folder.to_string()`**: micro-allocs; the first needs
+  a `Borrow`-friendly moka key design, the second an `Option<&str>`
+  widening of `_with_perms` signatures. Both queued for a micro-alloc
+  sweep with `bench_hex_ids`-style gates.
+
+## Notes
+
+- `deltaUpload.hash.test.ts`'s pre-existing "3-lane pool beats
+  sequential" gate does not hold in this 4-core CI-class container
+  (0.9-1.0x isolated, repeatedly) — environmental, unrelated to this
+  round's changes, left untouched.
+- The frontend engine floor (`node >= 24`) makes `npm ci` require npm
+  ≥ 11 lockfile resolution; on a Node 22 box use `npx npm@12 ci`.
+
+## Follow-ups seeded for round 7
+
+- JWT claims `Arc<str>` end-to-end (see above).
+- Thumbnail 304/cache path vs ACL ordering (see above).
+- `fetchFolderListing` returns empty `favoriteIds`/`sharedIds` since the
+  combined `/listing` route was removed — the files-view badge sets are
+  seeded empty on navigation (functional regression flag, not perf).
+- Search page lacks a stale-response `seq` guard (files view has
+  `loadSeq`); a slow stale filter response can clobber a newer one.
+- `list_folder_resources` clones `row.name` only because `icon_class_for`
+  borrows it later — reorder to let the name move.
+- Swimlane/photos virtualization (carried from round 5).

+
+## Summary
+
+| # | change | key metric | before → after |
+|--:|---|---|---|
+| 1 | Photos timeline incremental grouping/layout | 50-page (3k-photo) scroll drain | 76 500 → 3 000 group ops (**25.5x**) / 23.0 → 2.2 ms (**10.6x**) |
+| 2 | Range-seek per-request authz duplication removed | per-seek authz on a shared-drive scrub | WARM 0.67 → 0 µs/seek; **COLD 1362.66 → 0 µs/seek** (a drive-resolve query per seek) |
+| 3 | `/resources` row→DTO name clone → move | allocs/row (500-row page) | 10.004 → 9.004 (**500 allocs saved**, 1.00/row) |
+
+## [1] Photos timeline — O(N²) re-group + re-layout per page → incremental builder
+
+The photos view appended each 60-item page with `items = [...items, ...page]`
+and re-derived both `groups` (O(N), a `new Date()` per photo) and `photoRows`
+(O(N) row layout) over the whole accumulated list on every page — so paging to
+photo N re-grouped + re-laid-out everything loaded so far, Σ ≈ O(N²/60) of
+main-thread work during the scroll (the exact class ROUND6 fixed for the files
+listing). The DOM was already windowed (`VirtualRows`); this was the derivation
+feeding it.
+
+Because photos arrive newest-first (`media_sort_date DESC`), grouping is
+append-only: a page only ever extends the last date bucket or adds buckets
+after it, never mutates an earlier group. The new `PhotoTimeline`
+(`lib/utils/photoTimeline.ts`) exploits that — an append re-buckets only the
+fresh page and re-lays-out only the groups that changed, reusing every
+untouched group's cached rows; any other change (config, deletion, filter
+toggle, non-append) falls back to a full rebuild. The pure `buildPhotoRows` is
+the verbatim reference the gate holds it equal to.
+
+Gates: the incremental output is deep-equal to `buildPhotoRows` at EVERY page
+of the drain (both square + justified layouts); config-change / deletion /
+width=0 fall back to a correct full rebuild; grouping work collapses ≥5x and
+wall ≥3x.
+
+```
+cd frontend && npx vitest run src/lib/utils/photoTimeline.bench.test.ts --disable-console-intercept
+# photo timeline 50×60: before 76500 timestamp reads / 23.0 ms
+#                       after   3000 timestamp reads /  2.2 ms
+#                       (25.5x fewer grouping ops, 10.6x wall)
+```
+
+## [2] Range downloads — duplicate per-seek authz + access-notify removed
+
+`download_file_impl` resolves the file once via `get_file_with_perms` (authz +
+access-notify + metadata), then the Range branch called
+`get_file_range_preloaded_with_perms`, which re-ran `require_file` (authz) +
+`notify_file_accessed` per request. Media players and PDF viewers fetch a file
+*exclusively* through Range requests — a `bytes=0-` probe then one request per
+seek — so every seek in a scrub re-authorized a file the request-level gate had
+already cleared. The share-landing and WebDAV range paths already authorize
+once then read via the non-perms `get_file_range_preloaded`; the REST handler
+now does the same (and the now-unused `_with_perms` range method is deleted).
+
+Safety: the request-level `get_file_with_perms` still gates every request
+(denies before the Range branch runs), so the removed per-seek re-check
+bypasses nothing — the bench asserts the member is granted and a non-member
+denied.
+
+```
+cargo run --release --features bench --example bench_range_seek_authz
+# seeks/scrub=200 (member of a shared drive, viewer grant)
+# arm                        wall ms    µs/seek
+# BEFORE per-seek (WARM)        0.13       0.67   <- moka hit + uuid parse, removed
+# BEFORE per-seek (COLD)      272.53    1362.66   <- a grant-cascade drive-resolve
+#                                                    QUERY per seek, removed
+# AFTER  per-seek (removed)     0.00       0.00
+# A 200-seek scrub of a shared video stops paying ~272 ms of authz queries
+# when the drive-role cache is cold (cross-drive recipient, or 30 s TTL expiry
+# mid-scrub). notify_file_accessed (a throttled hook call) is likewise removed
+# per seek.
+```
+
+## [3] `/api/folders/{id}/resources` row→DTO mapping — clone name → move name
+
+The listing maps each owned `FolderResourceRow` into a DTO but cloned
+`row.name` into it (`name: row.name.clone()`) — one avoidable `String` heap
+alloc per listed folder/file. The folder branch uses fixed icon classes, so
+`row.name` is simply moved; the file branch computes its name-derived icon /
+category classes first (they borrow `&row.name`), then moves `row.name` in. One
+fewer alloc per row, identical output.
+
+```
+cargo run --release --features bench --example bench_resource_row_map
+# rows=500
+# arm             allocs   wall ms   allocs/row
+# BEFORE (clone)    5002     0.841       10.004
+# AFTER  (move)     4502     0.810        9.004
+# Saved 500 allocs (1.00/row) — the per-row name clone removed; output identical.
+```
+
+## Deferred / flagged (not shipped this round)
+
+- **Thumbnail ACL-before-304 (security posture — needs maintainer decision).**
+  `get_thumbnail_impl` runs `require_permission(Read)` before the ETag-304 and
+  moka/disk short-circuits, so a shared-album recipient pays a grant-cascade
+  query per thumbnail revalidation. Moving authz *after* the cache would make
+  thumbnails "authorized at creation time only" — a user whose access was
+  revoked could still fetch cached thumbnails of files they once could see.
+  That is a deliberate security-posture change, not a perf tweak; left for a
+  security review. The safe alternative (back the non-owner authz with the
+  existing `drive_role_cache`, or a `Borrow<str>` cache key that removes the
+  per-request `to_string`) is queued for round 8 with an alloc/query bench.
+- **`batch_operations` `Arc<str>` → `String` per item.** `copy_file_with_perms`
+  / `move_file_with_perms` take `Option<String>`, so the batch path's
+  `target_folder: Arc<str>` is re-`to_string()`-ed per item, defeating the
+  Arc. Widening those `_with_perms` signatures to `Option<&str>` touches the
+  trait + impl + stub + ~7 call sites — a contained refactor better done
+  deliberately with its own alloc bench; queued for round 8.
+- **List-view O(N²) re-derive (favorites / recent / trash / shared-with-me /
+  shared swimlanes).** Same class as [1] but on typically-smaller lists;
+  each infinite-scroll page re-derives `entries` / `byId` / `sections` /
+  `lanes` over the full accumulated set. Deferred — the incremental-builder
+  cost isn't yet justified at those sizes; revisit if any surface reaches
+  thousands of rows.
+- **Serial independent DB pairs → `join!` (token refresh, login, cross-drive
+  move, CardDAV discovery, NC PROPFIND enrichment).** Overlapping independent
+  round-trips saves 1 RTT *under real PG latency*, but the ROUND6 authz-fan-out
+  rejection showed the overhead can wash the win out on local-socket PG. These
+  need a decide-by-bench with an injected-latency arm (like the ROUND6 `::text`
+  A/B) before adoption — queued for round 8, not guessed at here.
+
+## Correctness-adjacent (surfaced by the round-7 hunt — not perf, flagged for follow-up)
+
+- **`fetchFolderListing` returns empty `favoriteIds`/`sharedIds`**
+  (`frontend/src/lib/api/endpoints/folders.ts`) since the combined `/listing`
+  route was removed — the files-grid star/shared badges are seeded empty on
+  every navigation. The same removal also dropped the 304 conditional
+  fast-path, so a folder navigation now pages the full body (`cache: no-store`)
+  instead of a bodiless 304 on unchanged folders (mitigated only by the
+  in-memory `folderCache`). Functional regression, not perf.
+- **Search page lacks a stale-response guard**
+  (`frontend/src/routes/search/+page.svelte`): the query `$effect` awaits
+  `searchFiles` with no `seq`/AbortController, so a slow stale query can
+  resolve after and clobber a newer one. The files view's `loadSeq` is the
+  pattern to mirror.

+# Round 8 — shared-album thumbnail authz: cache the folder-grant cascade decision
+
+Benchmark-gated, same rule as ROUND2-7: every change ships with a BEFORE/AFTER
+benchmark and equivalence/safety gates; an AFTER that doesn't beat its BEFORE
+gets rolled back. This round touches the authorization engine, so the bench
+carries hard **safety gates** (recipient allowed, outsider denied, and a
+revoke-denies-immediately test) and the change is additionally validated
+against the full `--cfg integration_tests` authz suite.
+
+Measured on 4 cores / 15 GiB, local PostgreSQL 16 (fsync off), release profile.
+
+## Summary
+
+| # | change | key metric | before → after |
+|--:|---|---|---|
+| 1 | `cascade_grant_cache` for File/Folder Read checks | shared-album thumbnail revalidation (100-photo) | 2576 → 2.70 µs/thumb (**~950x**); 257.6 → 0.27 ms/view |
+
+## [1] Shared-album thumbnails — folder-grant cascade query per thumbnail → cached
+
+`get_thumbnail_impl` runs `require_permission(Read, file)` on every request,
+ahead of the ETag-304 and moka/disk cache short-circuits. For the **owner** (or
+any drive member) that's a `drive_role_cache` hit — ~1 µs, no query. But a
+**shared-album recipient** — someone granted a *folder* (the album), not drive
+membership — fails the drive-role precheck in `PgAclEngine::check_inner` and
+falls through to `file_cascade_grant_exists`: an `role_grants ⋈ folders`
+ltree-ancestor (`lpath @>`) query, once per file. Browsers revalidate immutable
+thumbnails constantly (`If-None-Match`), so the same `(recipient, file, Read)`
+decision was recomputed on every thumbnail of every view — a shared 100-photo
+album cost ~100 grant queries per "navigate away and back".
+
+The safe fix keeps the check exactly where it is — **authz is never skipped**,
+the ordering is unchanged — and memoises only its *result* in a new
+`cascade_grant_cache` (`(Subject, Resource, Permission) → bool`, 30 s TTL). It's
+consulted only after the drive-role precheck fails, so a caller who later gains
+a drive grant short-circuits above it and can't be shadowed by a stale entry.
+
+**Invalidation** mirrors `drive_role_cache`'s documented convention exactly:
+explicit `invalidate_all` on every File/Folder `set_role` / `clear_role` (the
+direct share/revoke path — infrequent next to thumbnail reads, so a full flush
+is cheap and keeps a revoke *immediate*); the indirect paths (group-membership
+changes, resource moves, grant `expires_at` expiry) are caught by the 30 s TTL,
+"rather than a deep invalidation tree".
+
+Safety gates in the bench (hard asserts): the folder-grant recipient is allowed
+on every album file, an outsider is denied, and — critically — after a warm
+cache serves `allowed`, a `clear_role` on the shared folder makes the very next
+check **deny** (proving the grant-write flush; without it the stale `true`
+would still serve). Also validated against the full `--cfg integration_tests`
+authz suite (grants, nested groups, drive membership, read-only freeze).
+
+```
+cargo run --release --features bench --example bench_thumbnail_cascade_cache
+# thumbs=100 (recipient holds a folder grant, no drive membership)
+# arm                          wall ms    µs/thumb
+# BEFORE (query/thumb)          257.60     2576.04   <- folder-cascade query per thumbnail
+# AFTER cold (first view)        84.18      841.76   <- distinct files miss+populate the cache
+# AFTER warm (revalidation)       0.27        2.70   <- all cache hits (~950x vs BEFORE)
+# Safety gates PASSED: recipient allowed, outsider denied, clear_role revoke
+# denies immediately (grant write flushed the cache).
+```
+
+## Notes
+
+- The batched search Read path (`check_files_read_batch`) is unchanged — it
+  already resolves a page of files in one round-trip and isn't the
+  per-thumbnail hot path; it neither reads nor writes this cache, so no
+  consistency coupling is introduced.
+- First-view cost is unchanged (distinct files are cache misses that populate
+  the cache); the win is on revalidation + repeat views, which is where the
+  thumbnail traffic concentrates. A folder-level cascade cache would also cut
+  the first-view N-queries to one-per-folder, but needs a file→parent-folder
+  resolution and a wider invalidation story — deferred.
+- The ACL-before-304 *ordering* (running authz before the 304/cache
+  short-circuits) is left intact — with the cascade decision now cached, the
+  authz on the revalidation path is a memory hit, so the "zero DB work on a
+  304" intent is restored without moving (and thus without weakening) the
+  security check.

+
+## [1] Blob decorators — the trait-default fallthrough was re-adding HEAD-before-PUT
+
+ROUND3 §8 made chunk writes skip the remote exists-probe by introducing
+`put_blob_from_bytes_unsynced` (content-addressed keys make re-PUTs
+overwrite-safe). But `RetryBlobBackend` and `CachedBlobBackend` never
+overrode it, so the **trait default** routed every decorated `_unsynced`
+call back through the probing `put_blob_from_bytes` — silently reinstating
+HEAD+PUT per chunk on every remote deployment with retry or cache enabled
+(the recommended object-store setup). `EncryptedBlobBackend` and
+`MigrationBlobBackend` already forwarded correctly.
+
+Both decorators now forward `put_blob_from_bytes_unsynced` and `sync_blobs`
+to their inner backend (Retry wraps the former in its retry loop; the
+durability sweep is deliberately NOT retried — a failed fsync must surface,
+not be re-issued after the kernel may have dropped the dirty pages).
+`CachedBlobBackend` keeps its local write-through population on the
+unsynced path (shared `cache_bytes_write_through` helper, no eviction sweep
+— matching the historical write-path behavior) so post-upload readers
+(thumbnail/EXIF/face hooks) still hit the cache.
+
+```
+cargo run --release --features bench --example bench_s3_put
+# 500 x 256 KiB chunk PUTs at concurrency 8, 10 ms/request stub
+# [1] raw backend    BEFORE 1519 ms (500 HEADs) → AFTER 765 ms (0)   2.0x
+# [3] retry(s3)      BEFORE 1524 ms (500 HEADs) → AFTER 766 ms (0)   2.0x
+#     cache(s3)      BEFORE 1535 ms (500 HEADs) → AFTER 803 ms (0)   1.9x
+#     cache(enc(retry(s3)))  1571 ms (500)      →       812 ms (0)   1.9x
+# gates: BEFORE probes == chunks, AFTER probes == 0, cache write-through
+#        populated on BOTH routes (2×chunks files present)
+```
+
+## [2] NC PROPFIND page enrichment — 3 serial round-trips → `tokio::join!`
+
+Every Depth:1 PROPFIND page enriches its ≤500 children with three
+INDEPENDENT batched reads (favorites `= ANY`, oc:fileid `= ANY`, dead
+props `= ANY`), previously awaited in sequence. This is the round-7
+deferred "serial pairs" item, and the one pair the round-7 notes ranked
+worth gating (3 round-trips, per page, on the hottest sync path).
+
+Decide-by-bench with injected per-round-trip latency (0/0.25/1/5 ms),
+because ROUND6 showed concurrency can LOSE on local-socket PG (the authz
+`try_join_all` rejection). It doesn't here — these are three fat batched
+queries whose **server-side execution** parallelizes across PG backends,
+so even the local-socket floor wins, not just the RTT overlap:
+
+```
+cargo run --release --features bench --example bench_nc_enrich_join
+# children=500, passes=100, p50 ms/page      serial    join!   ratio
+#   0 µs injected                             2.275    1.097   2.07x
+#   250 µs                                    6.273    2.481   2.53x
+#   1000 µs                                   9.163    3.441   2.66x
+#   5000 µs                                  22.050    7.709   2.86x
+# gate: identical favorite sets / id maps / dead-prop rows; adoption
+#       required no local-socket regression — it's a 2x win even there
+```
+
+Contrast with ROUND6 §8 (rejected): that fan-out issued ~200 single-row
+authz checks through the engine's cache layers; this overlaps exactly 3
+page-batched queries. Both files' and folders' page loops adopted it.
+
+## [3] Search enrichment — borrow+clone+reclassify → consume+carry
+
+`enrich_file` took `&FileDto`, cloned every owned String out of it, and
+RE-RAN the three display classifiers whose results the DTO already carried
+interned (`Arc<str>`, computed once in `FileDto::from`); the recursive
+branch maps the ENTIRE pre-pagination match set. The NC REPORT conversion
+(`file_dto_from_search`) then re-ran all three classifiers a SECOND time
+per emitted row. `SearchFileResultDto.{mime_type,icon_class,
+icon_special_class,category}` are now `Arc<str>` (`#[schema(value_type =
+String)]` keeps the OpenAPI shape; JSON output byte-identical), both
+enrichers consume their DTO, the intermediate `Vec<FileDto>`/`Vec<FolderDto>`
+materializations are fused away, suggest reuses the interned fields, and
+the NC conversion carries them (refcount bumps). The search-cache byte
+weigher keeps counting `.len()` per row — now an over-count of shared
+bytes, i.e. the conservative direction.
+
+```
+cargo run --release --features bench --example bench_search_enrich
+# rows=10000 passes=50 (p50 ns/row; allocs from pass 0)
+# [1] enrich_file   BEFORE 455.8 ns / 11.60 allocs → AFTER 222.7 / 2.20
+# [2] enrich_folder BEFORE 116.2 ns /  5.00 allocs → AFTER 127.6 / 1.00
+#     (folder wall flat: the AFTER window absorbs the input drop the
+#      BEFORE arm defers outside its timing; the alloc gate is the win)
+# [3] NC conversion BEFORE 2.700 ms / 15.40 allocs → AFTER 1.524 / 7.00
+# gates: 500 files + 500 folders field-identical; NC conversion
+#        field-identical vs a fresh classifier run
+```
+
+## [4] NC session — deep-clone per request → `Arc` end-to-end
+
+Every authenticated NC request paid: the extractor's `(**arc).clone()` — a
+DEEP clone of `NcSession` (~8-9 String allocs) despite its doc claiming
+"one Arc increment"; a chroot-cache hit cloning the stored `FolderDto` by
+value (~5 allocs, moka `get` clones `V`); and a session build that cloned
+`CurrentUser` for the extension, cloned `raw_username`, and `to_string`ed
+the span value. Now: `NC_CHROOT_CACHE` stores `Arc<FolderDto>`,

+## [5] Storage micro-pack
+
+Four independent A/Bs in one harness (`bench_storage_micro`, no Postgres):
+
+- **(a) Local chunk write** — `try_exists` (stat) + `File::create` →
+  one atomic `create_new` open; `AlreadyExists` IS the idempotent skip.
+  20k × 4 KiB fresh writes 2707 → 1286 ms (**2.1x**); re-put skips 1.08x.
+- **(b) CDC read prep** — `stream_chunks` took `Vec<String>`, forcing
+  every read to deep-clone the cached manifest's whole hash list before
+  the first byte; now it takes the manifest `Arc` and indexes. A
+  4096-chunk manifest × 200 reads: 819 400 → 0 allocs, 49.4 → 0.16 ms.
+  The Range path selects by index too — a `bytes=0-` probe of an N-chunk
+  video no longer clones N hashes.
+- **(c) Manifest miss herd** — `manifest_cached` used get→insert; K
+  concurrent cold readers each ran the SELECT. Now fast-get +
+  `try_get_with` (sentinel miss error keeps the positive-only contract —
+  moka never caches loader errors, so legacy blobs and DB failures stay
+  uncached). Herd of 64: 64 → 1 loads.
+- **(d) Chunk `Content-MD5` hex** — the last `format!("{b:02x}")`-per-byte
+  straggler (ROUND6 §7 shipped `hex_lower`); 18 → 1 allocs/digest, 10x.
+
+```
+cargo run --release --features bench --example bench_storage_micro
+```
+
+## [6] OCS capabilities — rebuilt per poll → memoized bytes
+
+`/ocs/v{1,2}.php/cloud/capabilities` is process-invariant (pure config),
+yet every poll re-built the ~40-node `json!` tree, re-read
+`OXICLOUD_BASE_URL` from the **environment**, ran three `format!`s and
+re-serialized. Both versions now serialize once into
+`OnceLock<[Bytes; 2]>`; a poll is a refcount bump. The payload builder
+takes its three config inputs directly (testable without `AppState`).
+
+```
+cargo run --release --features bench --example bench_capabilities_static
+# 50k polls   BEFORE 269.6 ms / 102 allocs/poll → AFTER 1.1 ms / 0  (237x)
+# gate: served bytes byte-identical for v1 and v2
+```
+
+## [7] `Drive::is_empty` — full-drive COUNT(*) sum → `EXISTS OR EXISTS`
+
+The deletion precheck only needs a boolean, but aggregated every live
+folder + file in the drive. `EXISTS` stops at the first row.
+
+```
+cargo run --release --features bench --example bench_drive_is_empty
+# populated (100k files)  13.615 → 0.396 ms  (34.4x)
+# empty                    0.219 → 0.166 ms  (1.3x)
+# gate: identical booleans on both data shapes
+```
+
+## [8] favorites/recents row-map — the ROUND7 move that never got ported
+
+ROUND7 §3 removed the per-row `name` clone in `/folders/{id}/resources`;
+the same mapping in `/api/favorites/resources` and `/api/recent/resources`
+still cloned `path` + `name` + `blob_hash` per row (and `folder_handler`
+kept one `blob_hash` clone). All moved now — display classes computed
+before `name` moves, `path`/`blob_hash` moved instead of cloned.
+
+```
+cargo run --release --features bench --example bench_resource_row_map
+# [2] favorites/recents shape, rows=500
+# BEFORE (clone) 12.004 allocs/row → AFTER (move) 9.254  (−2.75/row)
+# gate: (name, path, content_hash, icon_class, category) identical per row
+```
+
+## [9] Folder rows — binary UUID decode (the ROUND6 §10 port)
+
+ROUND6 adopted binary-UUID decode for file listing rows (1.17x) and queued
+"other repos with the same shape"; `FolderDbRepository` never got it. All
+folder-row queries (`list_folders_batch` — every Depth:1 PROPFIND subfolder
+page — `get_folder`, descendants, search, suggest, and the write-path
+RETURNINGs, which share `row_to_folder`) now decode `id`/`parent_id` as
+binary `Uuid` (16 B vs 36 B on the wire, no server cast) and render once
+app-side. Param casts (`$3::text IS NULL`), enum casts and the ltree
+`path::text` renders are untouched.
+
+**Honest verdict:** weaker than the file side. Four interleaved runs:
+1.00x (wash), 1.05x, 1.03x, and 1.07x at 1000 rows — folder rows are
+thinner than file rows, so the two casts are a smaller fraction of the
+page. Adopted on the consistent small win + growth with page size + the
+wire-bytes reduction; the first-run wash is inside the noise band.
+
+```
+cargo run --release --features bench --example bench_folder_uuid_decode
+# rows/page=500 passes=400 (interleaved)   mean      p50      p95
+# A ::text (before)                        1.061    1.039    1.310
+# B binary (after)                         1.027    1.012    1.269   1.03x
+# rows/page=1000: 1.758 → 1.639 mean                              1.07x
+# gate: identical (id, name, path, parent_id) tuples
+```
+
+## [10] Authz — folder-level cascade decision (the ROUND8 deferred item)
+
+ROUND8 memoised the per-file cascade decision, fixing revalidation; a
+shared N-photo album's **cold first view** still ran N near-identical
+ltree ancestor queries. The file decision now decomposes into exactly the
+two branches of the historical UNION: parent point-read (new
+`file_parent_cache`, 30 s TTL — grant writes don't alter parentage; moves
+are the same TTL-healed indirect path as before) → the FOLDER cascade
+decision (one ltree query per folder, shared by every sibling via the
+existing `cascade_grant_cache`, recursing into the Folder arm) → a
+direct-file-grant point lookup only when the folder half denies. The old
+UNION query is deleted; no decision changes, including the parentless
+edge (`folder_id IS NOT NULL` guard ≡ direct-only fallback).
+
+Safety gates (hard asserts): recipient allowed on every file, outsider
+denied, `clear_role` revoke denies IMMEDIATELY (the flush covers file and
+folder decisions — same cache), and NEW: a caller holding only a direct
+grant on one file is allowed that file and denied its siblings — proving
+the folder-level decomposition neither shadows direct grants nor leaks a
+file decision across siblings.
+
+```
+cargo run --release --features bench --example bench_thumbnail_cascade_cache
+# thumbs=100 (folder-grant recipient, no drive membership)
+# ROUND8 cold (union/file)      59.19 ms    591.91 µs/thumb
+# AFTER  cold (first view)      41.77 ms    417.73 µs/thumb   (1.42x)
+# AFTER  warm (revalidation)     0.13 ms      1.33 µs/thumb   (unchanged)
+```
+
+The first view is now bounded by the per-file parent PK reads (cheap, but
+still N point queries) + 1 ltree query — batching the parent resolution
+per page would need a wider API change; noted for a future round.
+
+## [11] SPA — `resolveLabel` linear directory scan → id-keyed index
+
+`resolveLabel`/`resolveRecipient` ran `contactCache.find(...)` — a linear
+scan over the whole system address book — once per rendered grant row /
+lane header on `/shared`, re-rendering on every page and role change:
+O(rows × directory). Now a `Map<id, Contact>` built once per cache
+identity (exactly like the existing `groupCache`).
+
+```
+cd frontend && npx vitest run src/lib/api/endpoints/recipients.bench.test.ts --disable-console-intercept
+# 50 frames × 30 rows @ C=5000: before 11.0 ms, after 0.8 ms (13.9x)
+# gates: labels identical (present + absent ids); comparisons rows×C → C
+```
+
+## [12] SPA — selection-prune guard + photos `matchMedia` hoist
+
+- `ResourceList`'s prune `$effect` built an O(N) id `Set` on every
+  infinite-scroll page even with nothing selected; guarded with
+  `selected.size === 0` (reactive, so it re-arms when a selection
+  appears). 100-page drain: 100 → 0 Set builds; pruned result identical
+  when a selection exists.
+- The photos timeline derive called `window.matchMedia(...)` per
+  recompute (every 60-photo page); hoisted to state fed by one
+  MediaQueryList `change` listener. P recomputes: P → 1 calls, identical
+  booleans, crossings propagate.
+
+```
+cd frontend && npx vitest run src/lib/components/listDerives.bench.test.ts --disable-console-intercept
+```
+
+## Deferred / flagged (not shipped this round)
+
+- **CalDAV authz-before-fetch reorder** (`calendar_service::get_event` /
+  `list_events` / by-uid fetch the calendar row before the authz check
+  only to read `.is_public`; running the already-required authz first and
+  fetching only on denial saves one SELECT per authorized private-calendar
+  read). Behavior-preserving (the OR commutes) but it reorders an authz
+  check relative to a data fetch — flagged for maintainer sign-off per the
+  authz-change convention, with the bench sketch in this round's notes.
+- **Per-page batched parent resolution** for §10 — would cut the cold
+  first view's N parent PK reads to one `= ANY` per page; needs a wider
+  engine API (batch check) — future round.
+- **`batch_operations` `Arc<str>` → `Option<&str>` widening** (ROUND7
+  deferred) — re-audited: 1 small alloc/item vs a per-item DB roundtrip;
+  still not worth the 2-trait/7-site churn alone. Standing verdict.
+- **JWT-claims `Arc<str>`** (ROUND6 deferred) — still open; touches
+  serde `rc` on `TokenClaims` + dozens of read sites. The 2 allocs/request
+  remain the cheapest known win on the /api path for a future round.
+
+## Correctness-adjacent (surfaced by the round-9 hunt — not perf)
+
+- `trash_service.rs` restore matches error text
+  (`format!("{}", e).contains("not found")`) instead of
+  `e.kind == ErrorKind::NotFound` — fragile to rewording; flagged.
+- The round-7 flags remain open: `fetchFolderListing` seeds empty
+  `favoriteIds`/`sharedIds`; the search page still lacks a stale-response
+  guard.

+# Static assets & API responses — precompressed siblings + explicit Brotli level
+
+Two related findings, one root cause: tower-http's `CompressionLayer` default
+maps to **Brotli QUALITY 11** (`async-compression Level::Default` →
+`BrotliEncoderParams::default()`, brotli-8.0.2 `encode.rs:323` — verified in
+source and empirically below). Quality 11 is a deploy-time setting; it was
+running per request on:
+
+- every SPA asset (`interfaces/web/mod.rs` layer): ~1.3 s CPU per 700 KiB
+  bundle per request;
+- every compressible API response (`main.rs` global layer): ~90 ms CPU per
+  64 KiB JSON response.
+
+Changes:
+
+1. **Precompressed statics.** `frontend/scripts/precompress.mjs` (build step,
+   node:zlib only) emits `.br`/`.gz` siblings for text assets; `ServeDir` now
+   uses `precompressed_br()/precompressed_gzip()` — a request costs a file
+   read, and clients get the *better* q11 bytes, paid once per deploy
+   (~1.4 s for the whole bundle).
+2. **Explicit level 4** on both `CompressionLayer`s
+   (`CompressionLevel::Precise(4)`) — the on-the-fly fallback for statics
+   without siblings, and the global API layer.
+
+## Reproduce
+
+```bash
+cargo run --release --features bench --example bench_static_precompress
+# tunables: BENCH_ASSET_KB=700 BENCH_REPS=30
+```
+
+## Results (4 cores, this container)
+
+**Per-request cost, 700 KiB JS-like asset (94 % compressible):**
+
+| mode                        | ms/request | speedup |
+|-----------------------------|-----------:|--------:|
+| BEFORE — on-the-fly Brotli  |   1,324.31 |   1.0×  |

+| **Precise(4)** (chosen) |    0.91 |     6.2 |
+| Fastest                 |    0.15 |     9.3 |
+
+- Statics: 3 orders of magnitude less CPU per request, while shipping
+  *smaller* bytes than the runtime default would at any reasonable level.
+- API responses: **99× less CPU** for ~15 % more bytes (5.4 → 6.2 KiB) —
+  `Precise(4)` is the classic dynamic-content operating point; `Fastest`
+  gives up too much density (9.3 KiB).
+- Historical note: an earlier review round REFUTED the "default is q11"
+  claim twice; the source line and the 90 ms/64 KiB measurement above settle
+  it the other way. Measure before believing — in both directions.

+# ZIP export — Stored for already-compressed media (vs Deflate-always)
+
+Every ZIP export path (`ZipService::create_folder_zip` for folder downloads +
+public share ZIPs, `BatchOperations::download_zip` for batch downloads) used to
+build **every** file entry with `Compression::Deflate`. The dominant "download
+folder" payload is photos/video (JPEG/HEIC/MP4/WebP), which deflate cannot
+shrink (~0 %) while costing ~40 MB/s of CPU per core — and `async_zip` runs
+deflate **inline on the writing tokio task** (inside `poll_write`), so a media
+folder download monopolised ~1 core for its whole duration.
+
+The change picks the entry compression from the file's MIME type at plan time:
+`Stored` for already-compressed content, `Deflate` otherwise. The shared
+predicate is `common::mime_detect::is_precompressed_mime` /
+`zip_entry_compression` — it mirrors the HTTP `CompressionLayer` exclusion
+list in `main.rs` (keep in sync), minus `x-tar`/`octet-stream` (containers of
+possibly-compressible data stay on Deflate so nothing ever gets bigger).
+
+## Reproduce
+
+```bash
+cargo run --release --features bench --example bench_zip_media
+# tunables: BENCH_MEDIA_FILES=48 BENCH_MEDIA_MB=4 BENCH_TEXT_FILES=24 BENCH_TEXT_MB=2 BENCH_REPS=3
+```
+
+Rebuilds the exact production writer stack (`ZipFileWriter::with_tokio(BufWriter(File))`,
+`write_entry_stream`, 64 KiB chunks) over a mixed corpus: 192 MiB incompressible
+"media" + 48 MiB compressible text (80/20 by bytes, a realistic media folder).
+
+## Results (4 cores, this container)
+
+| mode                  | wall s | cpu s | MB/s   | out MiB | speedup |
+|-----------------------|-------:|------:|-------:|--------:|--------:|
+| all-Deflate (BEFORE)  |  5.786 |  5.88 |   41.5 |   198.8 |   1.00× |
+| mime-aware (AFTER)    |  1.341 |  1.38 |  178.9 |   198.7 | **4.31×** |
+| all-Stored (bound)    |  0.150 |  0.19 | 1601.5 |   240.0 |  38.6×  |
+
+- **4.31× faster wall clock and 4.3× less CPU** on the mixed corpus, with the
+  archive **0.05 % smaller** (media never deflated anyway; text keeps Deflate).
+- The remaining 1.38 s CPU in mime-aware is the text deflate + CRC32 — the
+  irreducible part. Pure-media folders approach the all-Stored bound (the
+  archive becomes blob-read-bound instead of CPU-bound).
+- Side effect on the runtime: the writing task no longer occupies ~a full core
+  per media download — on a 4-core box that's ~25 % of total CPU handed back
+  to other requests for the duration of every archive.

+- `OXICLOUD_AUTH_METHODS` — allowlist of enabled methods (`password`, `magic_link`, or both). Default: both. Removing one produces distinct error_type codes so the SPA can render specific UX:
+  - Removing `password` → `POST /api/auth/login` → 403 `PasswordLoginDisabled`; password-based `register` → 403 `PasswordRegistrationDisabled`.
+  - Removing `magic_link` → `magic-link/send` → 403 `MagicLinkLoginDisabled`; login-purpose token redemption refuses.
+  - **Startup gate:** magic-link-only + no SMTP wired → server refuses to start (main.rs panics).
+- `OXICLOUD_AUTH_POLICIES` — additive policy switches. Today: `permit_magic_link_for_password_users`. Future variants (`Require...`, `Deny...`) reuse the same vector-shaped env var — no per-policy env-var proliferation.
+- `OXICLOUD_REQUIRE_VERIFIED_EMAIL` — when true, `POST /api/auth/login` returns 403 `EmailNotVerified` for accounts with `email_verified_at IS NULL`. Checked AFTER password validation (anti-enum — an attacker without the password can't probe verification state). **Admin accounts are exempt** from this gate to prevent a config flip from locking pre-existing admins out of their own instance.
+
+**Verification piggyback.** When the `EmailNotVerified` branch fires (password OK + email unverified), the login handler auto-sends a verification magic-link to the account via a distinct service method that bypasses the `has_password` eligibility gate — the password itself just proved identity, so mailbox-only trust isn't being extended beyond what the password already established. Response is 403 `EmailNotVerified` with "check your inbox"; re-submitting the same login re-triggers the send. This is why there is no unauthenticated "resend verification" endpoint — one would leak `has_password` state to unauthenticated callers.
+
+**OIDC-master rule.** When `OXICLOUD_OIDC_ENABLED=true`, magic-link login is hard-off regardless of `OXICLOUD_AUTH_METHODS`. Magic-link would bypass any 2FA / step-up the IdP enforces.

 ## What is deliberately out of scope
 
 - **Native TOTP / WebAuthn enrolment.** The eligibility predicate has room for a `Reject("mfa_enrolled")` branch once native MFA lands. OIDC delegation is the only MFA path today.
-- **External-user → internal-user promotion.** When an external user later sets a credential, today `is_external` stays true (they remain second-class for home folders, DAV, etc.). A future PR promotes them properly.
+- **External-user → internal-user promotion — SHIPPED.** `POST /api/auth/upgrade-to-internal` flips `is_external` to false, optionally sets a password (optional iff the deployment offers magic-link login), and provisions a personal drive via `PersonalDriveLifecycleHook::on_upgraded_to_internal`. Refused with distinguished `error_type` codes: `AlreadyInternal`, `ManagedByIdP` (OIDC users), `PasswordRequired`, `RegistrationDomainNotAllowed` (domain outside the register allowlist — invitations must not become a bypass of the operator's self-registration policy). Self-service only; admin-side upgrade endpoint is a follow-up.
 - **Session-kind discriminator.** A magic-link session is indistinguishable from a password session today. Scoped sessions (Option-B style: "magic-link sessions only access granted resources") are deferred.
 - **Differentiated session TTL for externals.** Refresh-token expiry is uniform today. Future env: `OXICLOUD_EXTERNAL_REFRESH_TOKEN_EXPIRY_DAYS`.
 - **Open Cloud Mesh (OCM) federation.** A third source for external provisioning. The `ExternalIdentityLifecycleHook::on_user_created` design accommodates the `source` discriminator (`magic_link` / `oidc` / `ocm`).
-- **Email-verified policy gates.** PR 23 introduced the `email_verified_at` signal; gating features (uploads, shares, etc.) on it is future work — likely a single `OXICLOUD_REQUIRE_EMAIL_VERIFICATION=true` env var that adds middleware to the relevant routes.
+- **Email-verified login gate — SHIPPED.** `OXICLOUD_REQUIRE_VERIFIED_EMAIL=true` gates login on `email_verified_at IS NOT NULL` (admins exempt). Gating other features (uploads, shares, etc.) on the same signal is future work; the plumbing is in place.
 - **Username rename via the API.** PR 24 makes `username` claim-once-immutable on `/api/auth/me/profile`. A future admin endpoint at `PATCH /api/admin/users/{id}` can override for typo correction; that surface is admin-policy territory, not user-self-service.
 - **Anti-enumeration latency parity.** The success and collision branches of `register` already use similar code paths, but a sophisticated attacker could still time-distinguish. Deferred; rate-limiting bounds the damage.
 - **Per-user opt-out of magic-link.** The `OPEN_TO_PASSWORD_USERS` flag is instance-wide today. A future per-account toggle for high-privilege users (admins, etc.) would need a column + extra eligibility branch.

+The pre-2026-07 model kept one row per `(subject, permission,
+resource)` triple in `storage.access_grants` — an editor was 4 rows,
+an owner was 6. The D-Prep migration
+(`20260730000000_role_grants.sql` + follow-ups through
+`20260801000002_drop_access_grants.sql`) collapsed that into one row
+per assignment, added the DB-side `grant_role` ENUM, renamed the
+former `admin` role bundle to `owner` (to disambiguate from
+`UserRole::Admin`, the JWT-level user-account privilege), and dropped
+`access_grants` entirely. Coverage extension migrations
+(`20260906…_role_grants_calendar_address_book`,
+`20260910…_role_grants_playlist`) folded the last three per-feature
+share tables (CalDAV / CardDAV / Music) into the same `role_grants`

+
+The grace window (default 15 days) preserves the audit / support answer to
+*"what happened to my access?"* for two weeks past expiration, then the row
+goes. Because the AuthZ engine's `expires_at` filter is at read time, the
+grace window has zero effect on live access decisions — an expired grant is
+invisible to `check(...)` even during the grace period. Cleanup only affects
+storage bloat and the `list_grants_*` history surface.
+
+The daemon runs inside the same process (`tokio::spawn` at startup, same
+lifecycle as trash-cleanup / storage-usage sweep), so no external scheduler
+is needed. An admin-triggered `POST /api/admin/internal/trigger-grant-cleanup`
+lets operators force a purge in test or incident scenarios; the internal-
+endpoints gate (`OXICLOUD_ENABLE_ADMIN_INTERNAL_ENDPOINTS`) applies.
+
+The [Share Integration](/architecture/share-integration) doc's reverse
+trigger takes it from there: when the daemon deletes the last `role_grants`
+row for a share-token subject, `trg_cleanup_share_on_grant_delete` fires and

Two triggers keep them in sync — one per direction — so neither side can outlive the other.
 
 ### Share deletion → grant cleanup
 
-Deleting a share row (`DELETE FROM storage.shares` via `DELETE /api/shares/{id}`) fires the `trg_cleanup_grants_token` trigger declared in `migrations/20260520000000_rebac_access_grants.sql`.

+The same pattern runs when the underlying resource is deleted: the per-resource-type triggers on `role_grants` (`trg_cleanup_role_grants_folder`, `trg_cleanup_role_grants_file`, `trg_cleanup_role_grants_drive`, `_calendar`, `_address_book`, `_playlist`) clean up the grants, and any share row referencing a deleted resource is then garbage-collected by the reverse trigger described below.

-`DELETE /api/grants/{grant_id}` on the **last** grant of a token row removes the matching `storage.shares` row, atomically and in the same transaction.

+`DELETE /api/grants/{grant_id}` on a token row removes the matching `storage.shares` row, atomically and in the same transaction. The `trg_cleanup_share_on_grant_delete` trigger (originally introduced in `migrations/20260612000001_share_grant_reverse_cascade.sql`, carried forward through the `role_grants` migration by `migrations/20260801000001_role_grants_cascade_triggers.sql`) watches `role_grants` for `DELETE` events with `subject_type='token'` and deletes the paired share row **iff no other grants for the same `subject_id` still exist**:
 
 ```sql
-AFTER DELETE ON storage.access_grants:
+AFTER DELETE ON storage.role_grants:
     IF OLD.subject_type = 'token' THEN
         DELETE FROM storage.shares
          WHERE id = OLD.subject_id

                               AND subject_id   = OLD.subject_id);
 ```
 
 The `NOT EXISTS` guard makes it safe in two important cases:
 
-- **Multi-grant tokens** — if a token had several permission rows (e.g. read+share, were that ever to be allowed), revoking one leaves the share row intact. Only the final revocation triggers cleanup.
-- **Forward-cascade re-entry** — when the original DELETE comes from `storage.shares`, the forward trigger is already deleting these grant rows. The reverse trigger then tries to delete a share row that's already gone, finds no row, and the statement is a no-op. No recursion.
+- **Multi-role tokens** — the schema doesn't currently allow more than one role on a token (public share-links are always `viewer`), but the guard is still correct for the general case. Reserved for a future extension where a token might carry multiple assignments.

-Net effect: revoking the last grant on a token via the grants API and deleting the share via `DELETE /api/shares/{id}` are now equivalent — both end in a clean state with zero rows on either side.

 ### Resource deletion
 
 Both triggers compose cleanly with resource lifecycle:
 
-- A folder/file delete → `trg_cleanup_grants_*` removes the grants → `trg_cleanup_share_on_grant_delete` removes the share rows that just lost their last grant. One delete on the resource cleans up everything downstream in a single transaction.

+
+### Expired shares — background purge
+
+Public shares with an expiration date follow the general expired-grant
+lifecycle: the AuthZ engine treats them as unusable the moment `expires_at`
+passes (inline filter, no separate expiry check), and the `GrantCleanupService`
+daemon physically deletes the underlying `role_grants` row after a grace
+window (default 15 days, `OXICLOUD_GRANT_CLEANUP_GRACE_DAYS`). When it does,
+the reverse trigger described above fires and reaps the paired `storage.shares`
+row in the same transaction. Expired public shares vanish end-to-end without
+operator intervention. See
+[ReBAC Authorization → Post-expiry cleanup](/architecture/rebac-authorization#post-expiry-cleanup)
+for the daemon and its env vars.
 
 ### Pre-existing orphans
 
-The `20260612000001` migration also runs a one-shot `DELETE FROM storage.shares WHERE NOT EXISTS (… token grants)` to garbage-collect any orphans that accumulated before the reverse trigger existed.

+
+## Configuring which methods are offered
+
+Two environment variables control the self-service surface (OIDC is orthogonal — see `OXICLOUD_OIDC_ENABLED`).
+
+### `OXICLOUD_AUTH_METHODS`
+
+Comma-separated allowlist of `password` and/or `magic_link`. Default `password,magic_link`.
+
+| Configuration | Effect |
+| --- | --- |
+| Unset or `password,magic_link` | Both methods allowed (default) |
+| `password` | Password login OK. Magic-link send / redeem → 403 `MagicLinkLoginDisabled` |
+| `magic_link` | Password login → 403 `PasswordLoginDisabled`. Password-based `register` → 403 `PasswordRegistrationDisabled`. Email-only signup still works |
+
+**Startup gate.** If `magic_link` is the only method allowed AND no SMTP transport is configured (`OXICLOUD_SMTP_HOST` empty), the server refuses to start with a fatal message. A magic-link-only policy without a working mailer silently locks every user out.
+
+**OIDC master rule.** When `OXICLOUD_OIDC_ENABLED=true`, magic-link login is **hard-disabled** regardless of this list. The IdP is the identity boundary; magic-link would bypass any 2FA / step-up policy the IdP enforces. The startup gate above does **not** trigger in this case — OIDC provides the login path.
+
+Legacy alias: `OXICLOUD_OIDC_DISABLE_PASSWORD_LOGIN=true` still removes `password` from the effective allowlist.
+
+### `OXICLOUD_REQUIRE_VERIFIED_EMAIL`
+
+Default `false`. When `true`, `POST /api/auth/login` returns 403 `EmailNotVerified` for any account whose `email_verified_at IS NULL`.
+
+**Order matters:** the verified-email check runs **after** password validation. An attacker without the password sees only the generic `Invalid credentials` shape — they can't probe whether an account's email is verified.
+
+**Verification piggyback.** When the branch fires (password OK, email unverified), the server auto-sends a verification magic-link to the account's registered address using the same login request. The user sees `EmailNotVerified` in the response and a "check your inbox" hint on the login page; resubmitting the form re-sends the link. This is why there is no separate "resend verification" endpoint — offering an unauthenticated one would leak `has_password` state.
+
+**Admin exemption.** Admin accounts (role `admin`) are exempt from this gate at login, regardless of `email_verified_at`. Rationale: an operator who flips the flag on an existing deployment must not lock the admin(s) out of their own instance. Fresh admin accounts created via `POST /api/setup` or `POST /api/admin/users` are stamped verified at creation; the exemption covers pre-existing accounts that predate the flag.
+
+**Auto-verified on creation:** OIDC-JIT users, admin-created users (`POST /api/admin/users`), and the first-run setup admin (`POST /api/setup`). Verification is only ever missing on regular users who signed up before the flag was turned on.
+
+## Login identifier dispatch
+
+`POST /api/auth/login` accepts either a username (no `@`) or an email (contains `@`) in the `username` field. The two namespaces are provably disjoint — usernames forbid `@` — so the dispatch is unambiguous and both paths return the same session shape.
+
+`POST /api/auth/magic-link/send` mirrors this convention. The `email` field can be either an email or a username; the server resolves username → registered email before rate-limiting so both shapes share one budget (no bypass).
+
+## Registration flow
+
+Since PR 18, both `username` and `password` are optional on `POST /api/auth/register`. The only required field is `email`.
+
+| Combination | Result |
+| --- | --- |
+| `email + password` | Classic signup — account gets a password hash; user can log in immediately |
+| `email + password + username` | Same, plus the username is claimed at creation |
+| `email` only | Email-only signup — no password stored; server sends a welcome magic-link. Clicking it creates a session and stamps `email_verified_at`. The user can later claim a handle via `PATCH /api/auth/me/profile` and set a password via `PUT /api/auth/change-password` |
+
+The response body is uniform across success, email collision, and username collision — the SPA does not learn whether an address is already taken. The real reason lands in the audit log.
+
+### `OXICLOUD_DISABLE_REGISTRATION`
+
+Turns the endpoint off entirely (returns 403 `RegistrationDisabled`).
+
+### `OXICLOUD_REGISTRATION_ALLOWED_EMAIL_DOMAINS`
+
+Comma-separated allowlist. Rejected registrations return 403 `RegistrationDomainNotAllowed`. Distinct from `OXICLOUD_EXTERNAL_EMAIL_DOMAINS`, which gates external-user **invitations**; self-registration and invitations have independent policies.
+
+## Magic-link eligibility
+
+`POST /api/auth/magic-link/send` looks up the resolved email → user, then applies the eligibility ladder:
+
+1. **OIDC-linked user** → refused with `reason="oidc_user"`. Unconditional; the IdP is the security boundary and may enforce MFA that magic-link would sidestep.
+2. **Has a password configured** → refused with `reason="has_password"` (default). Set `OXICLOUD_AUTH_POLICIES=permit_magic_link_for_password_users` to allow — this weakens the password to mailbox-strength for affected accounts; opt-in only.
+3. **No credential** (typical external user or fresh email-only signup) → allow.
+
+The verification-piggyback flow above deliberately **bypasses the `has_password` gate** — that path is only reachable after the user has already proven identity via password on the same login request, so mailbox-only trust is not being extended beyond what the password already established.
+
+## Auth policy vector
+
+`OXICLOUD_AUTH_POLICIES` is a comma-separated list of additive policy switches. Distinct from `OXICLOUD_AUTH_METHODS` (which enables/disables a method wholesale), each entry here grants a specific exception or restriction to default auth behaviour. Vector shape so future policies can be added by appending a token instead of introducing a new env var per behaviour. Variant names carry their own polarity (`Permit...`, future `Require...` / `Deny...`).
+
+| Token | Effect |
+| --- | --- |
+| `permit_magic_link_for_password_users` | Allow magic-link login for accounts that also have a password. OIDC-linked users are still refused. |
+
+Unknown tokens are logged-and-skipped at startup so a typo doesn't silently zero the vector.

+
+## DAV clients (WebDAV / CalDAV / CardDAV): app passwords only
+
+DAV surfaces at `/webdav/`, `/caldav/`, and `/carddav/` accept HTTP
+Basic Auth **only against app passwords** — the user's regular account
+password is refused on those paths. This is intentional and cannot be
+switched off.
+
+Reasons:
+
+- **Uniformity across account types.** Magic-link-only accounts (email-
+  only signup) and OIDC-linked accounts have no local password to send
+  over Basic Auth. App passwords are the one credential shape that
+  works for every account type.
+- **Revocable and scoped.** An app password can be revoked
+  individually without touching the account password. Losing a phone
+  or rotating a client only affects that client.
+- **Bounded blast radius on phishing / leak.** A leaked account
+  password grants web login (which the SPA can gate with 2FA / step-up
+  in future); an app password grants only the DAV surface it was
+  minted for.
+
+**User workflow:** in the OxiCloud web UI, *Profile → App Passwords →
+Create*, name it, copy the token shown once, and use `username +
+token` in the DAV client. See
+[DAV Client Setup](/guide/dav-client-setup#before-you-start-get-an-app-password).
 
 ## Security Model
 
-- local passwords are hashed with Argon2id
-- access control is role-based (`admin` and `user`)
-- refresh tokens support session renewal without forcing frequent re-login
+- Local passwords hashed with Argon2id
+- DAV surfaces (WebDAV / CalDAV / CardDAV) accept **app passwords only** — the account password is refused on `/webdav/`, `/caldav/`, `/carddav/` by design (see above)
+- Access control is role-based (`admin` and `user`)
+- Refresh tokens support session renewal without forcing frequent re-login
+- Login endpoint uses anti-enumeration response shapes — bad-username and bad-password return the same 403
+- Magic-link `send` returns a uniform 200 whether the account exists or not; the truth lands in the `audit` log target
 - OIDC can coexist with local auth or disable password login entirely
+- OIDC-enabled deployments have magic-link login hard-disabled to prevent IdP-MFA bypass

Removing `magic_link` disables `POST /api/auth/magic-link/send` (returns 403 `MagicLinkLoginDisabled`) and the redemption path for login-purpose tokens. **Startup gate**: if `magic_link` is the only method allowed AND no SMTP transport is configured (`OXICLOUD_SMTP_HOST` empty), the server refuses to start. **OIDC master rule**: when `OXICLOUD_OIDC_ENABLED=true`, magic-link login is hard-disabled regardless of this list (would otherwise bypass IdP-enforced MFA / step-up). Legacy alias: `OXICLOUD_OIDC_DISABLE_PASSWORD_LOGIN=true` still removes `password` from the list. |
+| `OXICLOUD_AUTH_POLICIES` | — | Comma-separated additive policy switches. Each token grants an exception or restriction to the default auth behaviour; empty (unset) = pure defaults. Recognised tokens: `permit_magic_link_for_password_users` (allow magic-link login for accounts that also have a password — off by default because magic-link would weaken the password to mailbox-strength; OIDC-linked users are still refused regardless). |
+| `OXICLOUD_REQUIRE_VERIFIED_EMAIL` | `false` | When `true`, `POST /api/auth/login` returns 403 `EmailNotVerified` for any account whose `email_verified_at` is NULL.

Admin-created (`POST /api/admin/users`) and setup-admin (`POST /api/setup`) users are auto-verified. OIDC-JIT users are also stamped verified at creation. |

+# Drives
+
+A **drive** is a self-contained storage space with its own folder tree,
+its own members, its own quota, and its own settings. Drives are how
+OxiCloud separates "my personal files" from "our team's shared files"
+without mixing them together.
+
+Every user who signs up with a full account gets a **Personal drive**
+right away. On top of that, an admin can create **Shared drives** for
+teams, projects, or departments.
+
+> **Guest recipients (from a shared link)** don't get a Personal
+> drive. They only see the specific items that have been shared with
+> them.
+
+## Personal drives vs Shared drives
+
+| | Personal drive | Shared drive |
+|---|---|---|
+| **Who owns it** | You | A person, or a group of people |
+| **Who can see the content** | Only you (until you share individual items) | Every member |
+| **How storage is counted** | Against your personal quota | Against the drive's own quota |
+| **Can members be added** | No — it's yours alone | Yes — that's the point |
+| **Who creates it** | Created for you at sign-up | Created by your admin |
+| **Can it be deleted** | No — it lives as long as your account does | Yes, by the drive Owner |
+
+You can't turn your Personal drive into a Shared drive, or the other
+way round — they're different things by design.
+
+## Switching between drives
+
+Your drives appear in the sidebar under **Drives**. Click one and the
+file browser jumps into that drive's contents. The breadcrumb at the
+top of the file view always shows which drive you're currently in, so
+you never wonder where a file will land when you upload it.
+
+If someone else has added you to their Shared drive, it shows up in
+the sidebar automatically — nothing to accept or install.
+
+## Roles inside a Shared drive
+
+Inside a Shared drive, each member has a **role** that decides what
+they can do. Each role includes everything the role above it allows.
+
+| Role | What they can do |
+|---|---|
+| **Viewer** | Browse the drive and open files. See the trash bin (but not act on it). |
+| **Editor** | Plus upload new files, create folders, rename, and modify existing content. |
+| **Owner** | Plus delete files, share files with people outside the drive, rename the drive, add and remove members. |
+
+Your Personal drive doesn't have members or roles — it's always just
+you, and you can do everything.
+
+> **Editors can't delete.** In a Shared drive, only Owners send files
+> to the trash or empty it. If an Editor uploads a file by mistake,
+> they ask an Owner to remove it. This is deliberate — it prevents an
+> Editor from clearing content the team relies on. Personal drives
+> don't have this restriction (you're always your own Owner).
+
+## Drive settings — what an Owner can change
+
+Drive Owners can rename the drive and manage its members: add someone,
+remove someone (except the last remaining Owner), change a member's
+role, or set an expiration date on a membership.
+
+Other settings — **quota** and **policies** (see below) — are set by
+your OxiCloud admin, not by drive Owners. This is a compliance
+choice: if Owners could relax a policy, mint a share, and then
+re-enable the policy, the policy wouldn't really enforce anything.
+Owners can see the current settings, but changing them goes through
+the admin.
+
+## Policies — per-drive guardrails
+
+Every drive comes with a set of **policies** — safety switches that
+shape what's allowed inside the drive. Only admins can turn them on
+or off. Members see the current setting when it affects what they
+can do.
+
+| Policy | What it controls |
+|---|---|
+| **Sharing individual files** | Whether members can share specific files or folders with people outside the drive. When off, access happens only through drive membership. |
+| **Public links** | Whether members can create anonymous "anyone with the link" URLs. Turn off for anything sensitive. |
+| **Inviting people by email** | Whether members can share with someone who doesn't have an account yet (an email invitation with a magic-link sign-in). |
+| **Cross-drive move** | Whether files can be moved from this drive into another drive. Turn off to prevent members from relocating content out of a sensitive drive via the UI. |
+| **Owner list changes** | Locks the Owner roster. After the admin sets the Owners, no Owner can add, remove, or demote another Owner — only the admin can. |
+| **Include in Photos** | Whether photos in this drive appear in the global **Photos** view. Off by default for non-default drives; turn on for shared drives that really are photo libraries (e.g. "Family Photos"). |
+| **Include in Music** | Whether audio files in this drive appear in the global **Music** view. Same shape as photos — off by default, on for drives that are actually music libraries. |
+| **Read-only (freeze)** | Full freeze. When on, **every mutation on the drive is refused** — new files, edits, deletes, renames, sharing, membership changes. Members can still read and download. Nothing on the drive changes until the admin unfreezes it. Use for archives, publications, legal holds, or account wind-downs. |
+
+> **Cross-drive move blocks the UI move, not download-then-re-upload.**
+> If you need to stop content from ever leaving a drive, you need
+> stricter controls (file-egress policies are a future feature).
+
+> **Read-only is a hard freeze.** Even the trash-retention janitor
+> pauses on a read-only drive — items past their normal 30-day
+> lifetime stay in trash until the drive is unfrozen. This is
+> intentional: the whole point of the freeze is that *nothing*
+> changes, including automated cleanup. Once unfrozen, the next
+> retention pass catches up on anything that aged during the freeze.
+
+## Storage and quota
+
+- **Personal drive files** count against your account's storage
+  quota. If you're near your limit, uploads to your Personal drive
+  stop working until you free space.
+- **Shared drive files** count against the drive's own quota, set by
+  the admin. Your account quota isn't affected by files in Shared
+  drives — collaborating in a 1 TB Shared drive costs you no personal
+  bytes.
+- Two identical files stored in different drives are only stored once
+  on disk. Deduplication happens behind the scenes, so a file shared
+  between drives doesn't cost double.
+
+## Trash — one per drive
+
+Every drive has its own trash bin. Deleting a file in a Shared drive
+moves it into that drive's trash — not into your Personal drive's
+trash. This keeps each drive's history self-contained.
+
+- **Viewers** see the trash so they know what's been removed.
+- **Owners** restore items or empty the trash.
+- Deleting a whole Shared drive also empties its trash — nothing
+  spills into other drives.
+
+See [Trash & Recycle Bin](/guide/trash) for the standard trash
+lifetime and behaviour.
+
+## Sharing individual files and folders
+
+Sharing an individual file or folder works exactly the same in any
+drive — see [Sharing](/guide/sharing) for the full recipe. The
+drive's **policies** (above) might restrict some options (no public
+links, no email invitations) — the share dialog just hides the
+options that are disallowed.
+
+The drive itself isn't public-linkable. If an outsider needs to see
+one file from a Shared drive, share **that file** with them — not the
+whole drive.
+
+## Photos, Music, Favorites, Recent, Search — how drives affect them
+
+| Feature | What you see |
+|---|---|
+| **Photos** | Photos from your Personal drive, plus any Shared drive whose admin turned on **Include in Photos**. |
+| **Music** | Same as Photos — Personal drive plus opted-in Shared drives. |
+| **Playlists** | Your playlists can pull tracks from any drive you have access to (they're a curation tool, not tied to a specific drive). |
+| **Favorites** | Anything you've starred, across every drive you can reach. |
+| **Recent** | Files you've touched recently, across every drive you can reach. |
+| **Search** | Searches every drive you have access to. |
+
+Losing access to a drive removes its content from these views the
+next time they load — no stale entries.
+
+## Drives in WebDAV clients
+
+Native WebDAV works with all your drives. When you connect a client
+like **Finder**, **Cyberduck**, **Windows Explorer**, or **rclone**
+to `.../webdav/`, you land in your Personal drive by default — so a
+single-drive user's bookmark keeps working.
+
+To reach Shared drives, browse to `.../webdav/@drive/`. That folder
+lists every drive you have access to. Pick one and you're inside it,
+just like a regular folder.
+
+- Bookmark `.../webdav/@drive/` if you regularly switch drives —
+  it's your "drive picker."
+- Bookmark `.../webdav/@drive/<drive-name>/` if you usually work in
+  one specific Shared drive — that's your fastest route in.
+- Access-denied and "no such drive" look identical from a client
+  (both return "not found") — that's deliberate, to avoid leaking
+  which drives exist.
+
+::: warning Sync clients: pick ONE drive
+Never point a mirroring client (like `rclone sync`, a Finder mount,
+or a scripted `curl` loop) at `.../webdav/@drive/`. It would try to
+mirror **every** drive you can reach into local disk — twice for
+your Personal drive contents, and once for every large Shared drive
+you happen to be a member of.
+
+For sync, always target one specific drive: either bare
+`.../webdav/` (your Personal drive) or `.../webdav/@drive/<name>/`
+(one Shared drive).
+:::
+
+## Drives in Nextcloud clients
+
+Nextcloud desktop, Android, and iOS clients connect to your account
+and sync one drive at a time. When you add your account, it
+connects to your **Personal drive** by default. Adding the account
+in the app "just works" without any extra configuration.
+
+To sync a **Shared drive** from a Nextcloud client, add a **second
+account** in the app pointing at OxiCloud. At sign-in, pick the
+drive you want that account to sync. Each drive you want to keep in
+sync becomes one Nextcloud account entry.
+
+This is the same pattern Nextcloud itself uses for multi-location
+setups — the client stays simple, each drive stays self-contained.
+
+## Quick recipes
+
+**See which drives I can access.**
+Open the sidebar. Every drive you can reach is under **Drives**, with
+your Personal drive first.
+
+**Move a file from my Personal drive into a Shared drive.**
+Open the file → *More* → *Move* → pick the target drive → pick a
+folder → *Move here*. Your Personal quota goes down; the Shared
+drive's quota goes up. (Only works if the target drive's **Cross-drive
+move** policy allows it.)
+
+**Get a Shared drive for a team.**
+Ask an admin — Shared drive creation is an admin action. Tell them
+who the Owner should be (a person or a group), and what quota you
+need.
+
+**Add someone to a Shared drive I own.**
+Open the drive → *Members* → *Add* → pick a person or a group → pick
+a role → *Save*.
+
+**Change a member's role.**
+Open the drive → *Members* → click the member → change the role →
+*Save*.
+
+**Set an expiration on a member.**
+Open the drive → *Members* → click the member → set an **expiration
+date** → *Save*. After that date they lose access automatically.
+
+**Turn off public links or email invitations for a sensitive drive.**
+Ask an admin. They can flip either policy per-drive. Existing links
+stop working when the policy changes; members can't create new ones.
+
+**Freeze a drive (legal hold, archive, wind-down).**
+Ask an admin to set the **Read-only** policy on the drive. From that
+moment, no member — including Owners — can add, edit, delete,
+rename, share, or change membership. Reads and downloads keep
+working. The trash retention janitor also pauses on the drive, so
+items past their normal lifetime stay put. When the hold is over,
+the admin turns Read-only off and mutation resumes exactly where it
+was; retention catches up on the next tick.
+
+**Restore something from a Shared drive's trash.**
+Open the drive → *Trash* → pick the item → *Restore*. (Only Owners
+of the drive can do this. Viewers and Editors can see the trash but
+not act on it.)
+
+**Access a Shared drive from Finder / Cyberduck / Windows Explorer.**
+Connect to `.../webdav/@drive/`. The drives you can reach appear as
+folders; pick one and go.
+
+**Sync a Shared drive with the Nextcloud desktop app.**
+Add a second account in the app, pointing at the same OxiCloud
+server. At sign-in, pick the Shared drive. The app treats each
+drive-account pair as a separate sync.

+## Drives in the URL
+
+A user can own multiple [drives](/guide/drives) (one personal + any
+number of shared drives they've been added to). The WebDAV URL scheme
+lets you address them all, and the operator can choose between two
+layouts via `OXICLOUD_WEBDAV_DRIVE_LISTING_PREFIX` (default `"@drive"`):
+
+**Default — `"@drive"` sigil.** Bare `/webdav/…` addresses your default
+personal drive, keeping single-drive clients working with zero config.
+Explicit drive listing lives under the sigil.
+
+| URL | Target |
+|---|---|
+| `/webdav/` | Your default personal drive (back-compat) |
+| `/webdav/Documents/report.pdf` | A file inside your default drive |
+| `/webdav/@drive/` | Directory listing of every drive you can read |
+| `/webdav/@drive/<uuid-or-name>/…` | A specific drive by UUID or display name |
+
+**Empty prefix (`""`) — flat layout.** `/webdav/` IS the drive listing.
+Every drive appears as a top-level entry. No hidden default.
+
+| URL | Target |
+|---|---|
+| `/webdav/` | Directory listing of every drive you can read |
+| `/webdav/<uuid-or-name>/…` | A specific drive by UUID or display name |
+
+Set `OXICLOUD_WEBDAV_DRIVE_LISTING_PREFIX=""` for the flat layout.
+Any non-empty value replaces the sigil (e.g. `"drives"` gives you
+`/webdav/drives/<selector>/…`).
+
+**Trade-off with the empty prefix**: recursive DAV clients (Cyberduck,
+Finder, rclone default, NC desktop) will mirror ALL drives you can
+read, which can be a lot of storage. The `@drive` sigil keeps the
+default drive as the client's sync root and puts the picker behind an
+opt-in URL. Pick the empty prefix only when you want explicit
+multi-drive visibility.
+
+**Folder name collision note.** A user could name a folder `@drive`
+inside their default drive; that folder would then mask the drive
+picker for that user under the default sigil. Rare enough to be
+accepted; the sigil is renameable via the env var above if it becomes
+an issue.

-::: tip
-Always use HTTPS in production — Basic auth sends credentials in every request.
+::: warning Use an app password, NOT your account password
+DAV clients authenticate with an **app password** — a distinct, revocable,
+scoped credential. Your regular OxiCloud account password (used in the
+web login) will always be refused on `/webdav/`, `/caldav/`, and
+`/carddav/`.
+
+Why: app passwords are the only credential that works uniformly across
+all account types (password, magic-link-only, OIDC-linked), and they can
+be revoked individually without touching your account password.

 ### 7. Quota model
 
-The per-user `auth.users.storage_quota_bytes` field is **migrated to
-the user's personal drive's `quota_bytes`** in one step, then the
-column is deprecated (kept for one release cycle as a no-op, dropped
-in a later migration).
+Two ceilings, two different jobs:
 
-After the cutover:
-- Every drive owns its quota. Files inside a drive count against that
-  drive's `used_bytes` only.
-- A user who collaborates in a 1 TB shared drive sees their personal
-  drive's quota as "their" quota; the shared drive's quota is owned
-  by the team.
-- New drives default to a tenant-configured `OXICLOUD_DEFAULT_DRIVE_QUOTA_BYTES`
-  setting (separate env var, replacing today's per-user equivalent).
+- **Per-user envelope** — `auth.users.storage_quota_bytes` stays
+  as the canonical "how much can this user store on this server."
+  It caps the sum of `used_bytes` across **every personal drive
+  the user owns** (default + any secondaries — see §2). Shared
+  drives never count against any user envelope.
+- **Per-drive ceiling** — `drives.quota_bytes` is a per-drive cap
+  that applies **only to shared drives**. For personal drives
+  this column is `NULL` (unlimited at the drive layer); the
+  effective cap comes from the user envelope.
 
-`used_bytes` is maintained incrementally on every file insert/delete
-(plus a periodic reconciliation job to fix drift, similar to the
-existing per-user accounting).
+Why the asymmetry: a user's personal storage is a single budget
+that the operator has agreed to provide; splitting it into
+sub-quotas per personal drive is a sub-quota UX trap (users now
+have to plan how to allocate "their" bytes between drives they
+own). A shared drive's quota IS the team's resource budget, owned
+by the operator, set independently.
+
+#### Upload gate
+
+Pre-upload, both checks run, in order:
+
+1. **Drive cap** (`drives.quota_bytes`) — skipped when NULL.
+   Always skipped for personal drives by virtue of the NULL
+   convention; applies for shared drives.
+2. **User envelope** (`auth.users.storage_quota_bytes`) — runs
+   only when the target drive is personal. The check sums
+   `used_bytes` across the caller's personal drives (or, fast
+   path while no secondaries exist on the UI, reads the cached
+   `auth.users.storage_used_bytes`).
+
+For shared-drive uploads, only the per-drive check applies and the
+user envelope is untouched — collaborating in a 1 TB shared drive
+costs no personal bytes.
+
+#### `used_bytes` accounting
+
+Maintained incrementally on every file insert/delete in
+`storage.drives.used_bytes`. The user-side cached counter
+(`auth.users.storage_used_bytes`) is updated **only when the
+target drive is personal** — the per-upload delta hook reads
+`drives.kind` from the same query that already fetches
+`drives.used_bytes` for the drive-cap check, so the hot path adds
+zero round-trips.
+
+A periodic reconciliation job rebuilds both counters from ground
+truth:
+
+```sql
+-- Per-drive: unchanged from today.
+UPDATE storage.drives SET used_bytes = (
+    SELECT COALESCE(SUM(size), 0) FROM storage.files
+     WHERE drive_id = d.id AND NOT is_trashed
+) d;
+
+-- Per-user: sum of personal-drive used_bytes owned by the user.
+UPDATE auth.users u SET storage_used_bytes = COALESCE((
+    SELECT SUM(d.used_bytes)
+      FROM storage.drives d
+      JOIN storage.role_grants g
+        ON g.resource_type = 'drive' AND g.resource_id = d.id
+       AND g.role = 'owner'
+       AND g.subject_type = 'user' AND g.subject_id = u.id
+     WHERE d.kind = 'personal'
+), 0);
+```
+
+Fast-path variant while only default personals are exposed:
+
+```sql
+UPDATE auth.users u SET storage_used_bytes = COALESCE((
+    SELECT used_bytes FROM storage.drives WHERE default_for_user = u.id
+), 0);
+```
+
+Reconciliation runs on the maintenance pool — never blocks
+uploads. Drift between deltas and the sweep is bounded by the
+sweep interval (default 10 min).
 
 #### Quota mutation is OxiCloud-admin only
 
-Changing `drives.quota_bytes` is **not** in the drive `owner` role
-bundle (§4). It requires the tenant-level OxiCloud admin role
-(`auth.users.role = 'admin'`), checked at
-`PATCH /api/admin/drives/{id}/quota` — the only callsite that
-mutates the column. Drive owners can rename, edit policies, and
-manage members; they cannot self-grant capacity.
+Changing `drives.quota_bytes` (shared drives only) is **not** in
+the drive `owner` role bundle (§4). It requires the tenant-level
+OxiCloud admin role (`auth.users.role = 'admin'`), checked in the
+handler for `PATCH /api/drives/{id}/quota` (the admin gate lives
+on the endpoint even though the URL follows the `/api/drives/`
+prefix — the taxonomy split is by capability, not by URL depth).
+Drive owners can rename, edit policies, and manage members; they
+cannot self-grant capacity.
+
+Changing `auth.users.storage_quota_bytes` (the personal envelope)
+is likewise admin-only — same surface and audit pattern as today.
+
+Shape of the mutation:
+
+- **Request** — `PATCH /api/drives/{id}/quota` with body
+  `{ "quota_bytes": <int|null> }`. `null` (and defensively `0` or
+  any negative value the service normalises via `filter(|&q| q > 0)`)
+  means unlimited on the wire; the DB persists NULL and the
+  write-time gate short-circuits accordingly.
+- **Response** — `200 { "quota_bytes": <persisted_int|null> }`,
+  read back from the `RETURNING` clause so the admin sees the
+  authoritative value without a follow-up GET.
+- **Personal drives refuse with `400`** and a hint pointing the
+  operator at the user-envelope endpoint — the per-drive column
+  is always NULL for personal drives (§7 sum-of-personal invariant).
+- **Non-admin callers see `404`** (anti-enumeration; a `403` would
+  leak the endpoint's existence).
+- **Soft-shrink** — a new cap **may be set below the drive's
+  current `used_bytes`**. Existing content is untouched; the
+  write-time gate simply keeps refusing new writes until usage
+  drops back under. Matches xfs/ext4 `xfs_quota` and `edquota`
+  semantics. Owners can still delete files under an over-quota
+  state.
+- **Cache invalidation** mirrors `update_policies`:
+  `default_drive_cache.invalidate_all()` +
+  `invalidate_readable_all()` — both caches embed the full
+  drive row (including `quota_bytes`) and would otherwise serve a
+  stale cap for the 30 s TTL. Blow-the-whole-cache is fine because
+  quota mutation is admin-rare.
+- **Frontend** — admin UI at `/admin` drives tab renders a
+  gauge-icon button on shared-drive rows (personal rows show a
+  placeholder). The button opens the shared `<QuotaEditor>`
+  component (`frontend/src/lib/components/QuotaEditor.svelte`),
+  which the user-envelope modal also reuses. Endpoint-specific
+  wire encoding (`0` for users, `null` for drives) stays in the
+  parent `onsave` callback so the shared component never leaks
+  the magic value.
 
 Why this seam matters:
 
-- **Resource allocation is a tenant concern, not a drive
-  concern.** Storage bytes are a finite system resource the
-  operator pays for. The drive owner is empowered over the
-  drive's *use*; the admin is empowered over its *budget*. Same
-  separation that exists today between a user and the operator
-  who set `OXICLOUD_DEFAULT_QUOTA_BYTES`.
-- **Privilege-escalation seam closed.** Without this carve-out,
-  any user with a personal drive (= every internal user) could
-  raise their own quota by virtue of being its sole owner —
-  trivially defeating the quota system.
+- **Resource allocation is a tenant concern.** Storage bytes are
+  a finite system resource the operator pays for. The drive owner
+  is empowered over the drive's *use*; the admin is empowered
+  over its *budget*.
+- **Privilege-escalation seam closed.** Without the per-drive
+  carve-out, an Owner of a shared drive could raise its quota.
+  Without the per-user carve-out, any internal user could raise
+  their own envelope by virtue of owning their personal drive.
 - **Shared-drive coherence.** A shared drive's quota is set by
   the operator at provisioning; subsequent capacity requests go
-  through the admin, not the drive's group owners. Keeps the
-  capacity decision auditable and out of intra-team politics.
+  through the admin, not the drive's group owners.
 
-The admin endpoint is the same surface the operator uses today to
-change `auth.users.storage_quota_bytes`; D4 simply re-targets the
-write at `storage.drives.quota_bytes`. Audit log emits
-`drive.quota_changed` with `granted_by=<admin_user_id>` and the
-old/new values, mirroring the existing user-quota change event.
+Audit log emits `drive.quota_changed` (shared drives) and
+`user.quota_changed` (envelope) with `by=<admin_user_id>`,
+`new_quota_bytes`, `used_bytes`, and an `over_quota` boolean
+that flags the soft-shrink case. Personal-drive rejections emit
+`drive.quota_change_rejected` with `reason =
+"personal_drive_uses_user_envelope"`.
 
-**Chunk dedup vs per-drive quota.** With the CDC chunk store landed
-in v0.7.0 (see `delta_upload_service`, `upload_ingest`, instant
-upload by hash), a single chunk can be referenced by files in
-multiple drives. The accounting decision: **each drive counts the
-file's logical size in full against its own `used_bytes`** — dedup
-savings are server-side only and never visible in the per-drive
-quota number. This matches the existing per-user blob-dedup model
-and avoids the alternative "pro-rated quota" trap (which makes
-quota math depend on cross-drive content and breaks the user's
-mental model of "I have 1 TB free"). Reconciliation job sums file
-sizes per drive, not chunk allocations.
+Regression coverage — `tests/api/drive_quota.hurl` Steps 12–26
+pin the endpoint end-to-end: admin raise/lower, `null`/`0`
+unlimited normalisation, non-admin 404, personal-drive 400 with
+"envelope" hint, and the soft-shrink cycle (quota < used → new
+uploads 507, delete succeeds, sweep drops used_bytes, still 507
+until admin raises the cap).
+
+#### Multiple personal drives — schema-ready, no public surface
+
+The schema and service layer treat personal drives as "any
+personal drive owned by a user counts against the envelope," so
+secondary personal drives (`kind='personal' AND
+default_for_user IS NULL`) just work the day they ship. Today
+there is **no public API surface to create them** — the only
+`POST /api/drives` flow creates shared drives, and personal-drive
+provisioning happens at user registration via the lifecycle hook
+(§6). The capability matrix (§3) keeps the secondary column for
+the migration backfill path and for the future, but it is not
+user-reachable.
+
+When secondary personals are eventually exposed (e.g. a "Vault"
+end-to-end-encrypted drive kind, or a "Work" silo with a stricter
+policy bag), the quota model needs no change — the sum-of-personal
+formula already accounts for them.
+
+#### Chunk dedup vs per-drive quota
+
+With the CDC chunk store landed in v0.7.0 (see
+`delta_upload_service`, `upload_ingest`, instant upload by hash),
+a single chunk can be referenced by files in multiple drives. The
+accounting decision: **each drive counts the file's logical size
+in full against its own `used_bytes`** — dedup savings are
+server-side only and never visible in the per-drive quota number.
+This matches the existing per-user blob-dedup model and avoids
+the "pro-rated quota" trap (which makes quota math depend on
+cross-drive content and breaks the user's mental model of "I have
+1 TB free"). Reconciliation sums file sizes per drive, not chunk
+allocations.
+
+#### Migration
+
+One-shot at deploy: NULL out `drives.quota_bytes` for every
+`kind='personal'` row (D4 backfilled them from
+`auth.users.storage_quota_bytes` for the original "every drive
+owns its quota" plan). Then run the new reconciliation sweep once
+to resync `auth.users.storage_used_bytes` to "sum of personal
+drives" (excludes any shared-drive bytes the old delta path may
+have charged to it). Both steps idempotent.

+Each drive carries a `policies` JSON object. Six known keys for v1:

     "forbid_external_sharing":  false,  // blocks grants to is_external=true subjects

 }
 ```
 
+#### Mutation: OxiCloud-admin only
+
+`PATCH /api/drives/{id}/policies` is **OxiCloud-admin only** — the
+same carve-out that guards `drives.quota_bytes` and
+`users.storage_quota_bytes` (§7). The original design had policies
+owner-mutable, but that made them **self-policing soft caps**: an
+owner could disable `forbid_external_sharing`, mint the grant, and
+re-enable the policy. The audit log would capture the toggle but
+the policy gave no compliance-grade enforcement.
+
+Restricting mutation to the tenant operator closes that hole. Drive
+owners can still see the current policy values via
+`GET /api/drives` (read-only) but can't flip them; a UI surface that
+submits an admin ticket handles the self-service case for
+single-owner shadow.tech-style deployments.
+
+Anti-enumeration: non-admin callers receive `404` on the PATCH (the
+same response a non-existent drive would carry), never `403`, so a
+probe can't tell the policy state apart from the drive's existence.
+

-#### The Photos/Music asymmetry — defensible, not a smell
+No `default_for_user` OR-branch, no per-kind carve-out.
 
-Photos defaulting to "default-drive only" while Music defaults to
-"cross-drive" is the one case where two similar surfaces have
-different defaults. The justification is the noise-risk argument
-above: image content in shared drives is heterogeneous (often
-not "photos" in the gallery sense), audio content in shared
-drives is usually intentional. The capability flags let owners
-fix either case, but the defaults match what the typical user
-will want without configuration.
+**Default personal drive gets both flags set to `true` on
+creation.** The `PersonalDriveLifecycleHook` (§3) that creates
+the default personal drive on user provisioning populates
+`policies` with `{"include_in_photo_index": true,
+"include_in_music_index": true}`. Existing default personal
+drives get the same two flags via a one-shot backfill migration
+alongside the flag introduction. Net effect: every user's
+default personal drive is in scope from moment one, no user
+configuration required for the common case, but the SQL is
+kind-agnostic.
 
-If a uniform rule is ever preferred, the cheapest move is to
-flip Photos to cross-drive with `forbid_photo_index` as the
-opt-out (mirroring Music). That can land later without a schema
-change — just a behaviour change.
+**Non-default drives** (secondary personals, shared drives) are
+created with the flags omitted, so they stay out of scope until
+the owner explicitly opts in via the admin "Manage policies"
+modal.
+
+Flipping either flag on any drive is instant — the query reads
+`policies` at request time; the index itself is unchanged.
+Toggle-off on a default personal drive is *possible* (admins
+own the drive-policy mutation surface — see §8) but shows a
+confirm dialog in the UI ("this will empty the user's Photos
+timeline" / "…their Music library"), since it's an unusual
+action.
+
+#### Why symmetric (both opt-in) instead of asymmetric
+
+An earlier version of this section had Music default to
+cross-drive (`forbid_music_index` as an opt-out), on the
+argument that audio in shared drives is "almost always
+intentional content." That asymmetry created two problems:
+
+1. **Mixed-form flag naming** — one `include_in_*` and one
+   `forbid_*` with opposite meanings, hard to reason about in the
+   admin UI and the query layer.
+2. **The "shared audio is always intentional" claim doesn't
+   hold under scrutiny** — a work drive with a few voicemail
+   MP3s or a project drive with a stray podcast recording
+   shouldn't bleed into the personal music library any more than
+   a work drive with screenshots should bleed into Photos.
+
+Symmetric opt-in (`include_in_*_index` for both) fixes both.
+The "Family Music" case still works — the owner flips the flag
+once on drive creation, same one-time gesture as "Family Photos"
+under the pre-existing photo policy. The default-personal case
+(90%+ of users) needs no configuration for either surface.
+
+#### Face indexing — per-drive clustering, scope follows Photos
+
+Face indexing is bound to the same scope as `/api/photos` — the
+two surfaces show the same content set, so the face data behind
+that content lives in the same scope.
+
+Two layers to keep distinct:
+
+**Storage layer — per blob.** Face fingerprints are keyed on
+`blob_hash` (BLAKE3), FK to `storage.blobs.hash`. Fingerprints
+are deterministic from content bytes, and OxiCloud dedups
+content via blob hash — so a photo uploaded into N drives (or N
+times by N users) produces *one* fingerprint set, computed once,
+reused forever. Cascade-deletes when the blob is GC'd (ref_count
+→ 0). No `user_id`, `created_by`, `file_id`, `drive_id`, or
+group key on the fingerprint row: identity is the content.
+
+**Clustering layer — per drive.** Cluster computation runs
+*within* a drive: take every fingerprint reachable via a file in
+that drive (`storage.files.drive_id = X` JOIN
+`face_fingerprints` ON `blob_hash`), cluster them, emit clusters
+scoped to drive X. The query repeats per drive the caller can
+see (default personal + drives where
+`policies.include_in_photo_index = true` AND the caller has
+Read). Same-person fingerprints from different drives land in
+**separate** clusters by default — even when both drives reach
+the exact same blob, because clustering is keyed on drive, not
+on fingerprint identity.
+
+**Why per-drive clustering:**
+
+The drive is already the data boundary post-D6 — quota, sharing,
+trash, AuthZ all pivot on `drive_id`. The face library is part
+of the drive's content, not a cross-drive aggregate. Two
+properties fall out cleanly:
+
+- **Family-drive UX works.** Alice and Bob both members of
+  "Family" with `include_in_photo_index=true`. Alice uploads
+  Christmas photos; Bob uploads birthday photos. Grandma is in
+  both. Both see the *same* Grandma cluster in Family — one
+  merged cluster derived from fingerprints across both uploads.
+  Labels on the Family cluster are drive-scoped (anyone with
+  Photos access to Family sees them).
+- **Personal-drive isolation is preserved.** Each user's
+  personal drive is access-isolated by definition (nobody else
+  has Read on it). So a personal-drive cluster is visible only
+  to the drive's owner. The privacy guarantee falls out of
+  drive-access scoping — no separate user-id key needed.
+
+**Cross-drive clusters don't auto-merge.** Bob labelling
+"Grandma" in his Personal-drive cluster does NOT propagate to
+Family's Grandma cluster. Two separate visual clusters by
+default — even if the embedding similarity would otherwise
+match them. Rationale: auto-propagating private labels into a
+shared drive would silently expose personal classifications.
+Future UX can offer explicit per-cluster merging ("these two
+clusters are the same person") — user-driven, never silent.
+
+**Shared-drive opt-in is the consent surface.** Enabling
+`include_in_photo_index` on a drive is the owner saying "the
+photos in this drive are part of the drive's photo library,
+including the face data they contain." Doesn't add a new
+sharing surface — surfaces what was already visible (anyone
+with Read on a photo can see who's in it).
+
+**Implementation:**
+
+- `face_fingerprints(blob_hash, embedding, …)` — FK to
+  `storage.blobs.hash`, no `user_id` / `file_id` / `drive_id`
+  column. Cascade-delete via the blob ref-count → 0 GC path.
+- Cluster query: `SELECT … FROM storage.files f JOIN
+  face_fingerprints fp ON fp.blob_hash = f.blob_hash WHERE
+  f.drive_id = $1 AND NOT f.is_trashed` for each drive in the
+  caller's Photos-scope set.
+- Pre-D7 the legacy `(user_id, blob_hash)` query in
+  `face_indexing_service.rs::lookup_user` stays in place; D7
+  drops `user_id` from the column set in lockstep with the
+  global user_id retirement, leaving the fingerprint row keyed
+  on `blob_hash` alone. Both the `include_in_photo_index` policy
+  AND D7's user_id drop must land before face indexing can move
+  to the per-drive clustering model.

+# Plan — Expose dead properties as a REST metadata API
+
+## Context
+
+Migration `20260830000001` rekeyed `storage.webdav_dead_properties` from
+`(resource_path, user_id)` to a polymorphic resource id
+(`folder_id` XOR `file_id`) with `ON DELETE CASCADE`. The table is now a
+clean per-resource key-value store: `(resource id, namespace, local_name) → value`,
+shaped exactly like a generic metadata layer.
+
+Today only WebDAV (PROPPATCH / PROPFIND) reads and writes it. NextCloud DAV
+sees the rows (id-keyed, no path coupling) but isn't yet wired up to
+emit/consume them. No REST surface exists.
+
+We discussed the question "any interest in exposing this as a REST
+metadata API?" on **2026-06-30** during the rekey landing and agreed it's
+worth a follow-up plan but not part of the rekey itself. This document
+captures the design we sketched so we can pick it up without
+re-litigating.
+
+## Why this is worth doing now (and not before the rekey)
+
+| Pre-rekey schema | Post-rekey schema |
+|---|---|
+| `(resource_path, user_id)` key | `(folder_id XOR file_id, namespace, local_name)` key |
+| Path-keyed → invalidated on rename / move | Id-keyed → stable across rename / move (DB invariant) |
+| User-siloed → wrong for shared drives | Resource-state — correct under D1+ shared-drive semantics |
+| Service-layer deletes leak tombstones | FK `ON DELETE CASCADE` reaps on every delete code path |
+
+Pre-rekey, exposing the store via REST would have been wrong: REST clients
+operate on resource ids, but the store keyed on paths; cross-protocol
+parity would have been a mess. Post-rekey, the store IS already shaped
+like the API we'd want — a thin REST layer matches it 1:1.
+
+## Use cases
+
+| Use case | What it looks like | Why dead-props help |
+|---|---|---|
+| Photo annotations | captions, ratings (1-5), notes per photo | already keyed by `file_id`; round-trips via WebDAV without re-implementing |
+| Web-UI tags / labels | `oxi:user:tag/project=alpha`, color flags, "archived" markers | per-resource user metadata without new tables |
+| Folder UI preferences | default sort, default view mode, "favourite" flag | persistent per-folder, shared across users on shared drives |
+| Cross-protocol bridge | Thunderbird sets `oxi:lastsync=...` via PROPPATCH → web UI reads it via REST | one store, two surfaces — visibility goes both ways |

+
+Each use case is the same store; only the values differ. That's why
+exposing it as a generic API is more leverage than adding ad-hoc columns
+for any one of them.
+
+## API shape (decided)
+
+### Per-resource CRUD — nested under the resource
+
+```
+GET    /api/files/{id}/metadata                            → list all keys
+GET    /api/files/{id}/metadata/{namespace}/{name}         → fetch one value
+PUT    /api/files/{id}/metadata/{namespace}/{name}         → upsert (body = value)
+DELETE /api/files/{id}/metadata/{namespace}/{name}         → remove one key
+
+GET    /api/folders/{id}/metadata                          → list all keys
+GET    /api/folders/{id}/metadata/{namespace}/{name}       → fetch one value
+PUT    /api/folders/{id}/metadata/{namespace}/{name}       → upsert
+DELETE /api/folders/{id}/metadata/{namespace}/{name}       → remove one key
+```
+
+The `{kind}` is encoded in the URL prefix, so we don't carry a
+discriminator field. `{namespace}` and `{name}` are passed verbatim to
+the store; URL-encode the colon-containing namespaces
+(`oxi:user:tag` → `oxi%3Auser%3Atag`).
+
+This shape matches the rest of the API — `/api/files/{id}/thumbnail`,
+`/api/files/{id}/preview`, `/api/folders/{id}/contents` — and stays
+discoverable as a sub-resource of the file/folder.
+
+AuthZ goes through the `_with_perms` service path:
+- `Read` on the resource → GET allowed.
+- `Update` on the resource → PUT / DELETE allowed.
+- 404 on no-Read (anti-enumeration), 403 on Read-but-no-Update.
+
+GET (list) response shape:
+
+```json
+{
+  "properties": [
+    {
+      "namespace": "oxi:user:tag",
+      "name": "project",
+      "value": "alpha",
+      "updated_by": "<user-uuid-or-null>",
+      "updated_at": "2026-06-30T20:33:38Z"
+    },
+    ...
+  ]
+}
+```
+
+The resource itself is identified by the URL — no need to echo
+`{ "kind": ..., "id": ... }` in the body.
+
+### Cross-resource lookup — separate search endpoint (deferred to phase 3)
+
+Cross-resource search ("which files have `oxi:user:tag/project=alpha`?")
+is a fundamentally different operation from CRUD — it's a SEARCH, not a
+fetch. Nesting it under a single resource URL would be wrong, and
+overloading CRUD with `?filter=...` would muddy the shape. It lives at
+its own endpoint:
+
+```
+GET /api/search/metadata?namespace=...&name=...&value=...&kind=file
+```
+
+This separation has three concrete payoffs:
+
+- **CRUD path stays simple**: per-resource fetch/upsert/remove with no
+  query-string filter logic.
+- **AuthZ shape differs**: per-resource CRUD enforces permissions on
+  ONE resource; search must enumerate every resource the caller can
+  Read, then filter. That's expensive enough to need its own
+  rate-limit / pagination story. Isolating it keeps the CRUD path
+  cheap.
+- **Search can grow** more filter syntax (multiple keys, value
+  patterns, `>` / `<` comparisons) without touching the CRUD shape.
+
+Search is **phase 3** — it's not required for the read-only or
+read-write cases (phases 1 and 2). Don't build it until a UI feature
+asks for it.
+
+Note this is the LOW-VOLUME lookup option. Genuine tag-based faceted
+browse at scale needs a first-class tags table with indexes — not a
+metadata-table scan. The search endpoint exists for debugging, small
+instances, and occasional one-off queries. See "Out of scope" below.
+
+## Schema additions needed
+
+```sql
+ALTER TABLE storage.webdav_dead_properties
+    ADD COLUMN updated_by UUID NULL REFERENCES auth.users(id) ON DELETE SET NULL;
+```
+
+The `updated_at` column already exists. `updated_by` is the new bit —
+load-bearing if both WebDAV and REST are writing. Without it, "why did
+this caption change overnight?" is blind.
+
+Set on every `set()` / `remove()` (the latter currently has no provenance
+concept, but the audit value would be "who reaped it" — same column).
+`ON DELETE SET NULL` so a user delete doesn't lose the property itself,
+only the authorship — symmetric with how other audit columns in the
+schema behave (`created_by` on folders/files is `ON DELETE SET NULL` for
+the same reason).
+
+## Decisions to lock in before implementation
+
+### 1. Namespace policy — denylist or allowlist?
+
+Server-managed namespaces (`DAV:`, anything we want to use internally for
+sync state, locks, etc.) should be REST-write-rejected so REST can't
+poison live WebDAV behaviour.
+
+**Recommendation: denylist.** More permissive, less surprising, matches
+the WebDAV side (which lets clients write any namespace they please).
+Initial denylist:
+
+- `DAV:` — RFC 4918 live properties; server-managed.
+- `oxi:internal:*` — reserved for future server-managed properties.
+
+REST read is unrestricted; only write is filtered.
+
+### 2. Size limits
+
+Today no cap. WebDAV is bounded by `MAX_XML_BODY` (1 MB) on the request,
+but per-row there's no limit and no per-resource key-count limit. A
+REST API in the wild needs both:
+
+- per-value: **64 KB** (enough for any human-authored caption, JSON blob,
+  or sync token; rejects "use the metadata table as a file store"
+  abuse).
+- per-resource: **100 keys** (enough for any reasonable application;
+  rejects "use it as a directory listing").
+
+Both as 413 Payload Too Large on the offending endpoint.
+
+WebDAV PROPPATCH should adopt the same per-key limit (currently bounded
+only by the 1 MB body); per-resource count limit applies on the
+incremental write.
+
+### 3. Value content type
+
+Stored as `TEXT` today. If REST PUTs JSON, WebDAV clients reading it
+back via PROPFIND wrap it in their XML envelope and see `"{...}"` as a
+literal string. Defensible (it's "just a string"); document the
+convention.
+
+If we add a `content_type` column (RFC 4918 §15.5 `getcontenttype` on
+properties is murky), REST can return the original `Content-Type` to
+REST callers and WebDAV continues to see the literal value. Probably
+**not worth it** until a real use case needs it — adds a column + a
+write path branch for zero functional benefit today.
+
+### 4. Listing semantics
+
+Inlining child metadata into `GET /api/folders/{id}/contents` is
+tempting — fewer round-trips for the UI — but PROPFIND already pays this
+O(N) cost and it's expensive on big folders.
+
+**Recommendation: dedicated endpoint only.** No inlining. UIs that need
+per-child metadata can batch via `GET /api/files/{id}/metadata` calls
+in parallel (HTTP/2 multiplexing makes that cheap) until measured
+demand justifies a bulk endpoint.
+
+### 5. WebDAV-write hygiene
+
+REST writes go through the same `DeadPropertyStore::set` as PROPPATCH —
+no special branch. The denylist (above) gates which namespaces REST may
+write; WebDAV stays unrestricted.
+
+## Scope: phase 1 / 2 / 3
+
+### Phase 1 (read-only)
+
+GET endpoints only, nested under `/api/{files,folders}/{id}/metadata`:
+
+- `GET /api/files/{id}/metadata`                            → list
+- `GET /api/files/{id}/metadata/{namespace}/{name}`         → single
+- `GET /api/folders/{id}/metadata`                          → list
+- `GET /api/folders/{id}/metadata/{namespace}/{name}`       → single
+
+Plus the `updated_by` schema migration (so phase 2 doesn't break wire
+contracts).
+
+Use case unlocked: the SvelteKit UI can READ properties Thunderbird /
+DAVx5 / Cyberduck have written. Cross-protocol visibility, one
+direction.
+
+Cost: ~150 LOC handler + ~20 LOC migration. No new authz primitives —
+`Read` permission already exists.
+
+### Phase 2 (write)
+
+PUT + DELETE. Namespace denylist. Size limits.
+
+Decide first what the primary REST writer is:
+
+- **Photo captions**: probably wants a dedicated `/api/photos/{id}/caption`
+  endpoint that stores under a fixed `oxi:photo:caption` key. Generic
+  API still useful but not the obvious surface.
+- **Tags**: deserves a structured tags table (queryable, faceted search)
+  rather than k/v. Generic API is the wrong shape.
+- **Workflow state**: generic API IS the right shape — exactly what k/v
+  was designed for.
+- **Third-party integrations**: generic API is the right shape.
+
+If the primary writer turns out to be one of the structured-data cases,
+phase 2 may never ship — the read API plus a dedicated write endpoint
+per feature is the better factoring. The decision should be driven by
+real demand, not speculative design.
+
+### Phase 3 (cross-resource search)
+
+`GET /api/search/metadata?namespace=...&name=...&value=...&kind=file`
+with pagination. AuthZ enumerates resources the caller has Read on
+and filters in-engine.
+
+Scope guidance:
+
+- Low-volume **only**. Implemented as a sequential scan with
+  permission filter. No new indexes (the (`namespace`, `local_name`,
+  `value`) shape doesn't index cheaply, and adding `value` to a
+  composite index changes the table's write pattern).
+- Filter syntax stays minimal until a UI feature drives it. Start
+  with `namespace=` and `name=`; add `value=` literal match next; add
+  `value~=` pattern match only when needed.
+- Hard rate-limit per caller — search is expensive enough that an
+  unbounded REST client could starve the database.
+
+If demand for tag-based browse at scale ever materialises, do NOT
+extend this endpoint — build a dedicated tags table with an inverted
+index. Search-on-metadata is the debug/scratch tool, not the
+production tag system.
+
+## Out of scope
+
+- **Tags / faceted search** — deserves a first-class table with foreign
+  keys and a search index. The metadata API can hold tags as values,
+  but querying "all files tagged `alpha`" via the metadata table is a
+  full scan. Don't build features that need indexed tag queries on top
+  of this.
+- **Live properties** (RFC 4918 §15) — `getcontentlength`,
+  `creationdate`, `getetag`, etc. are server-computed. The REST API
+  exposes only dead properties; live properties are derived from the
+  resource and surface through their existing endpoints.
+- **Bulk write** — phase 2 could add a batch endpoint if needed, but
+  initial design ships one-at-a-time. Bulk read (list) is already
+  there.
+- **Versioning / history** — `updated_at` + `updated_by` give an audit
+  timestamp but not history. If someone wants "show me the previous
+  caption", that's a separate append-only journal table.
+- **WebDAV PROPPATCH size enforcement** mentioned above as "should
+  adopt the same limit" — actually applying the limit to PROPPATCH is
+  a separate small change, deferable.
+
+## Open questions left for implementation
+
+1. **Sub-resource name** — `/metadata` matches REST conventions and
+   reads naturally to API consumers; `/properties` would be more
+   WebDAV-faithful but users don't know what "dead properties" means.
+   Locked in: `/metadata`.
+2. **Permission for empty list** — GET on a resource with zero metadata
+   returns `{ properties: [] }` and 200, OR 404? RFC 4918 §9.1 says
+   PROPFIND on a resource that exists but has no requested properties
+   is 207 with empty `<D:prop>`. REST should mirror: 200 with empty
+   array. 404 only when the underlying resource doesn't exist (or
+   anti-enum 404 on no-Read).
+3. **Listing order** — alphabetical by `(namespace, name)`, or by
+   `updated_at DESC`? Probably the former (stable, deterministic).
+4. **Caching** — `ETag` on the list response? Cheap if the underlying
+   resource already emits one; we could derive a sub-ETag from
+   `MAX(updated_at)` across the metadata rows. Defer until UI asks.
+5. **NC DAV wiring** (see memory note
+   `project-nc-webdav-dead-props-unwired.md`) — the read API would
+   work over the unwired NC surface trivially since REST and NC DAV
+   read the same store; the unwired bit is just PROPPATCH/PROPFIND on
+   the NC URL prefix. Worth doing alongside phase 1 read so the cross-
+   protocol story is complete on day one.
+6. **Search endpoint shape** (phase 3, not phase 1) — the cross-
+   resource lookup `/api/search/metadata?...` will need pagination,
+   sort, and resource-kind filter; design when the first concrete
+   use case lands. Don't speculatively build it.
+
+## Verification (phase 1)
+
+1. Migration adds `updated_by`; downgrade leaves data intact (no
+   `DROP COLUMN` on rollback — just leave it; harmless).
+2. `cargo check` green; `cargo clippy --all-features --all-targets -D
+   warnings` green.
+3. New Hurl scenario `tests/api/metadata_api.hurl`:
+   - PUT a file via WebDAV, PROPPATCH a marker → 207.
+   - GET `/api/files/{id}/metadata/oxi%3Atest/marker` → 200 with the
+     value.
+   - GET `/api/files/{id}/metadata` → 200 with list containing the
+     marker.
+   - Asserts `updated_by` field is the authenticated user id.
+   - GET against a foreign user's file → 404 (anti-enum).
+   - GET `/api/folders/{id}/metadata` round-trip on a folder PROPPATCH.
+4. The existing `webdav_dead_properties.hurl` continues to pass —
+   read-only REST shouldn't perturb any existing write path.
+
+## Verification (phase 2)
+
+To be expanded when phase 2 starts. At minimum:
+
+- PUT writes round-trip via PROPFIND.
+- PUT to denylisted namespace → 403.
+- PUT exceeding per-value cap → 413.
+- PUT exceeding per-resource cap → 413.
+- DELETE removes via PROPFIND verification.
+- PUT/DELETE without Update permission → 403.
+
+## Memory notes to write when this lands
+
+- `project_metadata_api.md` — phase shipped, what's still open.
+- Update `project_webdav_dead_properties_drive_rekey.md` to mention
+  this API as the consumer that justified the id-rekey effort.
+- If the namespace denylist is contentious, capture it as
+  `feedback_metadata_namespace_denylist.md`.

+//! Basic-auth thundering-herd benchmark — K concurrent cache misses.
+//!
+//! Every WebDAV/CalDAV/CardDAV/NextCloud request authenticates through
+//! `AppPasswordService::verify_basic_auth`. The cache (TTL 300 s) used to be
+//! a plain get/insert: when a sync client holding K parallel connections hit
+//! an expired entry, all K in-flight requests missed simultaneously and each
+//! ran the full slow path — an Argon2id verification at ~64 MiB / t=3 / p=2
+//! apiece (100-300 ms CPU each). `try_get_with` now coalesces concurrent
+//! misses into ONE verification; failed verifications stay uncached.
+//!
+//! Sections:
+//!   BEFORE (emulated) — K concurrent bare Argon2id verifications, the exact
+//!                       work the old code fanned out per herd
+//!   AFTER             — K concurrent verify_basic_auth on a cold cache
+//!                       (single-flight: 1 verification, K-1 waiters)
+//!   warm-hit          — p50 of the cached path
+//!
+//! Gate: AFTER's process-CPU delta must be ~1 verification (< 2x a single
+//! verify), while BEFORE burns ~K of them. All K results must be Ok and
+//! identical.
+//!
+//! Run (needs Postgres up; reads DATABASE_URL / OXICLOUD_DB_CONNECTION_STRING
+//! from .env):
+//!   cargo run --release --features bench --example bench_auth_herd
+//! Tunables: BENCH_HERD (8)

+//! Azure download-path benchmark — whole-blob buffering vs streaming (ROUND4).
+//!
+//! The old `AzureBlobBackend::get_blob_stream` / `get_blob_range_stream`
+//! drained the ENTIRE blob (or range) into one `Vec<u8>` before yielding
+//! a single mega-chunk: whole-blob RAM residency per reader, TTFB = full
+//! download time, and with `read_prefetch() = 8` the CDC reassembly path
+//! could hold 8 entire chunk-blobs at once. AFTER forwards the SDK's
+//! page/body streams directly (first page still awaited eagerly so a
+//! missing blob is an up-front NotFound).
+//!
+//! Technique: a local axum stub speaks just enough of the Azure Blob GET
+//! REST surface (ranged 16 MiB pages, `x-ms-*` headers) for the REAL
+//! `azure_storage_blobs` client — the backend points at it via the new
+//! `endpoint_url` override (also the Azurite hook). The stub synthesizes
+//! blob bytes deterministically per offset, so it holds no buffer and
+//! the peak-live-heap metric isolates the CLIENT path. BEFORE is the old
+//! collect-everything logic copied verbatim; AFTER is the real
+//! `AzureBlobBackend`. BLAKE3 gates assert byte-identical payloads.
+//!
+//! Run (no Postgres needed):
+//!   cargo run --release --features bench --example bench_azure_stream
+//! Tunables (env): BENCH_MB (256) blob size, BENCH_TAIL_MB (128) range tail.

+//! used to each download the FULL blob from the remote backend and race

+//! (models a remote object store).

+//!   BEFORE (emulated) — K concurrent direct inner fetches, each draining
+//!                       the full stream (what the old miss path did)
+//!   AFTER             — K concurrent `CachedBlobBackend::get_blob_stream`
+//!                       on a cold cache

+//! Blob-cache index benchmark — `Mutex<LruCache>` vs moka byte-weigher
+//! (the ROUND11 deferred lead; no Postgres).
+//!
+//! `CachedBlobBackend` keeps its cache index in a
+//! `tokio::sync::Mutex<LruCache<String, CacheEntry>>`: EVERY cached chunk
+//! read acquires the one global async mutex to probe + LRU-promote (the
+//! promote needs `&mut`), so N-core read concurrency collapses onto a
+//! single serialization domain — and an N-chunk CDC file read is N
+//! acquisitions, with every other concurrent reader contending.
+//!
+//! AFTER: a `moka::sync::Cache` with a byte weigher — lock-free sharded
+//! reads with striped recency, byte-budget eviction handled by moka
+//! (replacing the manual `current_size` + `collect_evictions` machinery),
+//! and an eviction listener that unlinks the evicted `.blob` file (only on
+//! size-eviction — Replaced/Explicit must NOT unlink, gated below).
+//!
+//! Arms:
+//!   [1] pure index ops, K tasks × M hit-probes (the scaling ceiling)
+//!   [2] end-to-end warm-hit read (index probe + open + 64 KiB read),
+//!       K = 1/2/4/8 readers over a shared corpus
+//!   [3] safety gates: byte budget enforced + evicted files unlinked +
+//!       replaced entries keep their file + single-flight still coalesces
+//!       K concurrent misses onto 1 inner fetch
+//!
+//! Run:
+//!   cargo run --release --features bench --example bench_blob_cache_index
+//! Tunables (env): BENCH_OPS (200000), BENCH_FILES (256), BENCH_READERS (8)

+//! CalDAV parse-path benchmark — the write-side 8×-reparse and the
+//! read-side per-event copies (ROUND4).
+//!
+//! What changed:
+//!
+//!   • `CalendarEvent::from_ical` funnelled each of its 8 property
+//!     lookups through an extractor that re-ran the full `IcalParser`
+//!     (line unfolding + component tree) over the whole body — 8
+//!     complete parses per VEVENT on every CalDAV PUT, `8·(M+1)` on a
+//!     master+M-exceptions PUT, `8·N` on an N-event import. Now: one
+//!     parse, all lookups on the parsed component (value-only lookups
+//!     also skip the parameter-map build).
+//!   • `split_vevents` uppercased EVERY line into a fresh String.
+//!     Now: allocation-free case-insensitive prefix tests.
+//!   • `extract_vevent_chunk` (read side: every REPORT/GET, per event)
+//!     allocated a full uppercase copy of the stored body just to find
+//!     two tags. Now: memchr fast path + alloc-free CI scan fallback.
+//!   • `group_events_by_uid` (read side, per REPORT) cloned every
+//!     event's UID String. Now: borrowed keys.
+//!
+//! The OLD logic is copied verbatim into `mod before`; equivalence
+//! gates assert byte-identical parsed fields / chunk slices / grouping
+//! across a corpus incl. folded lines, params, VALARM, all-day,
+//! exceptions and mixed-case tags (exit 1 on any diff).
+//!
+//! Run (no Postgres needed):
+//!   cargo run --release --features bench --example bench_caldav_parse
+//! Tunables (env):
+//!   BENCH_EVENTS (200)  BENCH_PASSES (30)  BENCH_GROUP_N (5000)

+//! CalDAV whole-calendar response benchmark — buffered vs streamed (ROUND5).
+//!
+//! The REPORT path (no-range calendar-query, sync-collection) and the
+//! collection `.ics` GET used to (a) materialise EVERY event DTO of the
+//! calendar in one Vec (owned `ical_data` per row), then (b) render the
+//! complete multistatus / VCALENDAR into a second in-RAM buffer — the
+//! calendar resident twice, TTFB = full generation. AFTER streams ONE
+//! window-ordered scan (`MIN(start_time) OVER (PARTITION BY ical_uid)`)
+//! through a PG cursor and cuts pages at UID boundaries — same-UID rows
+//! never split, bundle order equals the buffered first-appearance
+//! order, and only a page of rows is resident. (A first keyset-paged
+//! shape re-aggregated per page — 3-4x wall — and a per-uid ANY
+//! hydration paid ~20 µs per index descent — both measured and
+//! discarded; see ROUND5.md.)
+//!
+//! This bench drives the REAL repository methods + adapter writers both
+//! ways at the repo layer (authz gates are identical constants on both
+//! sides and excluded). BEFORE uses the surviving buffered generator
+//! (byte-stable refactor of the old monolith) + a verbatim copy of the
+//! removed `generate_full_calendar_ical`. Gates: streamed concatenation
+//! byte-identical to the buffered output for BOTH the multistatus and
+//! the ICS body (seeded with strictly distinct start times so ordering
+//! is deterministic).
+//!
+//! Run (needs Postgres up; reads DATABASE_URL from .env):
+//!   cargo run --release --features bench --example bench_caldav_stream
+//! Tunables (env): BENCH_EVENTS (4000), BENCH_PAGE (500), BENCH_PASSES (9).

+//! OCS capabilities poll benchmark — rebuild-per-request vs memoized bytes.
+//!
+//! `/ocs/v{1,2}.php/cloud/capabilities` returns a payload that is
+//! process-invariant (pure config: base URL + emulated NC version), yet
+//! every NC desktop/mobile client polls it on connect and periodically.
+//! The old handler re-built the ~40-node `json!` tree — including a
+//! `std::env::var("OXICLOUD_BASE_URL")` lookup and three `format!`s —
+//! and re-serialized it on EVERY poll. Round 9 serializes both versions
+//! once into a `OnceLock<[Bytes; 2]>`; a poll is a `Bytes` refcount bump.
+//!
+//! The BEFORE arm is the production payload builder invoked per request
+//! (via the bench wrapper) + `serde_json::to_vec`, exactly the old
+//! handler flow (`Json(payload)` serializes with `to_vec`). The AFTER
+//! arm is the memoized-bytes flow. The equivalence gate asserts the
+//! served bytes are identical.
+//!
+//! Run (no Postgres needed):
+//!   cargo run --release --features bench --example bench_capabilities_static
+//! Tunables (env): BENCH_POLLS (50000)

+//! CardDAV REPORT generation benchmark — dead double vCard generation +
+//! O(N²) uid scan (BEFORE) vs single on-demand generation (AFTER).
+//!
+//! The old `handle_report` flow pre-generated a vCard for EVERY contact into a
+//! `Vec<(uid, vcard)>`, then `generate_contacts_response` did a linear
+//! `find(|(uid, _)| *uid == contact.uid)` per contact — O(N²) string compares
+//! — and *discarded* the result (`let _ = vcard`), because
+//! `write_contact_response` regenerates the vCard on demand anyway. The fix
+//! deletes the pre-generation and the scan, and converts `contact_to_vcard`
+//! from `push_str(&format!(…))` (one temp String per line) to
+//! `write!(&mut String, …)`.
+//!
+//! `mod before` below is a verbatim copy of the OLD code (old
+//! `contact_to_vcard`, old `generate_contacts_response` with the `vcards`
+//! parameter, and the then-current `write_contact_response`), so one binary
+//! measures both variants and byte-compares their output.
+//!
+//! Equivalence gate: BEFORE and AFTER XML must be byte-identical for every
+//! (N, prop-set) combination, and the old/new `contact_to_vcard` must agree
+//! byte-for-byte on every synthetic contact. Any mismatch exits 1 with the
+//! first differing offset.
+//!
+//! Run (no Postgres needed):
+//!   cargo run --release --features bench --example bench_carddav_report
+//! Tunables (env):
+//!   BENCH_REPS (5)   median reported

+//! CardDAV whole-book response benchmark — buffered vs cursor streaming
+//! (ROUND6).
+//!
+//! The REPORT path (addressbook-query, sync-collection) and the depth-1
+//! collection PROPFIND materialised EVERY contact DTO of the book in
+//! one Vec, then rendered the complete multistatus into a second in-RAM
+//! buffer — the book resident twice, TTFB = full generation. AFTER
+//! streams ONE ordered scan (`full_name, first_name, last_name`, the
+//! buffered listing's order) through a PG cursor and emits fixed-size
+//! pages (contacts carry no bundling constraint).
+//!
+//! Drives the REAL repository + adapter writers both ways at the repo
+//! layer (authz identical both sides, excluded). Gates: streamed
+//! concatenation byte-identical to the buffered output for the REPORT
+//! (getetag poll shape) AND the collection PROPFIND (allprop), seeded
+//! with strictly distinct names so ordering is deterministic.
+//!
+//! Run (needs Postgres up; reads DATABASE_URL from .env):
+//!   cargo run --release --features bench --example bench_carddav_stream
+//! Tunables (env): BENCH_CONTACTS (8000), BENCH_PAGE (500), BENCH_PASSES (9).

+//! NC chroot / default-drive resolution benchmark — 2 queries/request vs moka.
+//!
+//! The NextCloud basic-auth middleware wraps EVERY protected NC route and,
+//! even with app-password verification fully cached, used to resolve the
+//! chroot from scratch per request:
+//!
+//!   1. `find_default_for_user`  — drives JOIN folders  (drive_pg_repository)
+//!   2. `get_folder(root_id)`    — folders by PK
+//!
+//! The native `/webdav` surface repeats query 1 per request (Mode-B scope
+//! resolution), WOPI repeats it per call. The change memoises (1) inside
+//! `DrivePgRepository` and (2) in the middleware's `NC_CHROOT_CACHE`
+//! (both 30 s TTL). This bench isolates exactly that: the per-request DB
+//! cost of the chroot resolution — the two production query shapes vs a
+//! moka hit — under sync-storm concurrency against the real pool.
+//!
+//! Run (needs Postgres up; reads DATABASE_URL from .env):
+//!   cargo run --release --features bench --example bench_chroot_cache
+//! Tunables (env): BENCH_POOL (20), BENCH_SECONDS (4), BENCH_CONCURRENCIES ("8,64").

+//!
+//!   OLD   — N sequential `IS NOT DISTINCT FROM` queries (production today)
+//!   EQ    — N sequential plain `file_id = $1` queries (indexable, still N+1)
+//!   BATCH — ⌈N/500⌉ `file_id = ANY($1)` queries (one per PROPFIND page)
+//!
+//! Two table sizes are measured: the seeded-children-only table and one with
+//! extra noise rows (dead props on other resources), which is where the
+//! seq-scan cost of OLD shows up.
+//!
+//! Run (needs Postgres up; reads DATABASE_URL from .env):
+//!   cargo run --release --features bench --example bench_dead_props
+//! Tunables (env): BENCH_CHILDREN (2000), BENCH_PAGE (500 = PROPFIND_BATCH_SIZE),
+//!   BENCH_NOISE_ROWS (20000), BENCH_REPS (5).

+//! WebDAV drive-selector resolution benchmark — grants join/request vs moka.
+//!
+//! Every native `/webdav/<selector>/…` request (all verbs; MOVE and COPY
+//! twice) resolved its scope through `lookup_drive_selector` →
+//! `DriveRepository::list_readable_by`: a role_grants ⋈ drives ⋈ folders
+//! join with inline transitive-group expansion, GROUP BY + MIN(role) +
+//! ORDER BY — per request, uncached. The same join also ran per request
+//! in search, trash listing and the `GET /api/drives` picker.
+//!
+//! AFTER wires the per-user `readable_cache` (30 s TTL, single-flight,
+//! explicit invalidation on every membership/lifecycle mutation) into
+//! `DrivePgRepository` — this bench drives the REAL repository (cache,
+//! `try_get_with` and the per-hit `Vec` clone included), not a synthetic
+//! lookup, against the verbatim BEFORE query.
+//!
+//! Run (needs Postgres up; reads DATABASE_URL from .env):
+//!   cargo run --release --features bench --example bench_drive_selector
+//! Tunables (env): BENCH_POOL (20), BENCH_SECONDS (4), BENCH_CONCURRENCIES ("8,64").

+//! Isolates the variables the DTO-mapping change touches:

+//!   • `Arc::<str>::from(&'static str)` for the closed-set display fields
+//!     (icon class, icon special class, category) — always alloc + copy —
+//!     vs interned `Arc<str>` lookups (`intern_display` / `intern_mime`).
+//!   • `File::compute_etag` / `Folder::compute_etag` — `chars().take(16)
+//!     .collect::<String>()` + `format!` (2 allocs) vs one sized buffer.
+//!   • `format_file_size` — two `format!` calls per row vs one buffer.
+//!   • `Folder → FolderDto` — per-getter `.to_string()` clones + a
+//!     double-allocated etag vs `into_parts()` moves.
+//!
+//! The OLD mapping logic is copied verbatim into `mod before` so one binary
+//! reports BEFORE vs AFTER side by side, and an equivalence gate asserts the
+//! two produce byte-identical DTOs for every row (exit 1 on any diff).
+//!
+//! Sections:
+//!   1. File  → FileDto   wall time (p50 ns/row over BENCH_PASSES passes)
+//!   2. Folder → FolderDto wall time (same)
+//!   3. Alloc calls/row (counting global allocator wrapping System — the
+//!      lib crate sets no global allocator; mimalloc lives in main.rs only,
+//!      which examples do not link)
+//!   4. Equivalence gate: BEFORE output == AFTER output, field by field

+//! Face-indexing fan-out benchmark — unbounded spawn vs semaphore (ROUND4).
+//!
+//! `FaceIndexingService::spawn_index` fired one `tokio::spawn` per
+//! uploaded/copied image with NO ceiling; each task reads the full blob
+//! into RAM and decodes it before inference. A bulk upload of N photos
+//! therefore held up to N decoded images in flight simultaneously.
+//! AFTER: an `Arc<Semaphore>` sized to the effective core count
+//! (`OXICLOUD_FACES_INDEX_CONCURRENCY` override), permit acquired BEFORE
+//! the blob read — the exact `ThumbnailService::decode_semaphore`
+//! invariant ("peak memory = permits × image size").
+//!
+//! This is a *pattern* bench (like POOL-CONCURRENCY / RUNTIME): the real
+//! service needs Postgres + an ONNX model, so the task body models the
+//! dominant costs — full-file read + JPEG decode on the deterministic
+//! `bench_support` photo corpus — while the spawn/permit shape is copied
+//! from the service verbatim. Metrics: wall time, PEAK LIVE HEAP (exact,
+//! via counting allocator), decode results asserted identical.
+//!
+//! Run (no Postgres needed):
+//!   cargo run --release --features bench --example bench_faces_bound
+//! Tunables (env): BENCH_IMAGES (48), BENCH_PERMITS (effective cores).

+//! Batch-favorites AuthZ fan-out benchmark — serial `require` loop vs
+//! `try_join_all`.
+//!
+//! VERDICT (round 6): the fan-out measured WORSE on both the cold and the
+//! warm path against local-socket Postgres (see benches/ROUND6.md), so the
+//! production loop stays serial. This example is kept as the reproducible
+//! evidence for that rejection — re-run it if the DB ever moves behind real
+//! network latency, where the answer could flip.
+//!
+//! `FavoritesService::batch_add_to_favorites` pre-checks `Permission::Read`
+//! on every referenced resource. BEFORE awaited the checks one-by-one: for a
+//! "select all → add to favorites" over N items whose drive-lookup isn't
+//! cached yet, that is N sequential point-SELECT round-trips
+//! (`drive_of` per distinct file) before the batched insert even starts.
+//! AFTER fans the same checks out with `futures::future::try_join_all`
+//! (fail-fast on any denial preserved).
+//!
+//! This bench drives the REAL `PgAclEngine` (owner/drive-role caches
+//! included) against a seeded shared drive:
+//!   caller ──editor grant──▶ drive ─▶ root folder ─▶ N files
+//!
+//! Arms: cold engine (empty caches — the first-grid-load shape) and warm
+//! repeat (all moka — parity check, both arms should collapse).
+//!
+//! Equivalence gates: every check grants for the member on both arms, and
+//! both arms deny a control user with no grant.
+//!
+//! Run (needs Postgres up; reads DATABASE_URL from .env):
+//!   cargo run --release --features bench --example bench_favorites_authz
+//! Tunables (env): BENCH_FILES (200), BENCH_POOL (20).

+//! Micro-alloc benchmark: digest-hex rendering and NC id-batch marshalling.
+//!
+//! Two round-6 changes, both equivalence-gated against their verbatim
+//! BEFORE shapes and measured with a counting allocator:
+//!
+//! 1. `IncrementalHasher::finalize_hex` (upload_ingest.rs) rendered MD5 /
+//!    SHA-256 digests with `.map(|b| format!("{b:02x}")).collect()` — one
+//!    heap `String` per digest byte (16 / 32 allocs) per chunk finalize.
+//!    AFTER: `common::fmt::hex_lower` writes into one preallocated String.
+//!
+//! 2. `batch_resolve_ids` (NC webdav_handler) cloned every child id into a
+//!    `Vec<String>` and the id service keyed its result map by `String` —
+//!    ~3 heap allocs per child per page. AFTER the whole chain is borrowed:
+//!    `Vec<&str>` in, `HashMap<Uuid, i64>` out, `Uuid::parse_str` lookups.
+//!
+//! Run:
+//!   cargo run --release --features bench --example bench_hex_ids
+//! Tunables (env): BENCH_ITERS (10000), BENCH_CHILDREN (500).

+//! Web-UI folder listing benchmark — whole-folder rescan vs keyset pushdown.
+//!
+//! `list_resources_paged` (folder_db_repository.rs) pages the SPA files view
+//! with a UNION-ALL CTE (folders + files) and applies the keyset cursor
+//! OUTSIDE the CTE on computed columns (`sort_str = LOWER(name)`,
+//! `folder_first`). Postgres therefore scans every remaining row of the
+//! folder and top-N-sorts it on EVERY page — a 20k-file folder pays a full
+//! rescan per 200-row page.
+//!
+//! The AFTER shape pushes the cursor into each branch as a sargable
+//! row-value comparison (`(LOWER(name), id) > ($str, $id)`), gives each
+//! branch its own `ORDER BY … LIMIT`, and adds two expression indexes:
+//!   idx_files_folder_lname   (folder_id, LOWER(name), id) WHERE NOT is_trashed
+//!   idx_folders_parent_lname (parent_id, LOWER(name), id) WHERE NOT is_trashed
+//! The outer query then merges ≤ 2·limit pre-sorted rows.
+//!
+//! Modes (full drain of the folder in default "name" order, plus a
+//! modified_at parity check):
+//!   OLD/no-idx — the true BEFORE
+//!   OLD/idx    — new indexes alone, old query shape
+//!   NEW/idx    — the AFTER
+//!
+//! Equivalence gate: the drained (type, id) sequence must be identical
+//! across all modes; a mismatch aborts with exit(1).

+//! Round-11 log-writer benchmark — synchronous fmt layer (stdout under a
+//! global lock, on the async workers) vs `tracing_appender::non_blocking`
+//! with `lossy(false)` (audit lines must never drop; the emitting thread
+//! blocks only if the 128k-line channel fills).
+//!
+//! Two writer profiles:
+//!   - fast: stdout redirected to /dev/null (best case for the sync arm)
+//!   - slow: a writer that burns ~20 µs per line under the same lock,
+//!     modelling a laggy pipe / journald / TTY consumer
+//!
+//! The global subscriber can only be installed once per process, so the
+//! arm is chosen via env and the harness runs the binary once per arm:
+//!
+//!   BENCH_LOG_ARM=sync        cargo run --release --features bench --example bench_log_writer >/dev/null
+//!   BENCH_LOG_ARM=nonblocking cargo run --release --features bench --example bench_log_writer >/dev/null
+//!   BENCH_LOG_WRITER=slow BENCH_LOG_ARM=...   (slow-writer profile)
+//!
+//! Measurements print to stderr. Emits 4 workers × 25k events; reports
+//! total wall, per-event p50/p99/p999 emit latency, and (for the
+//! non-blocking arm) confirms zero dropped lines via a line count gate
+//! (lossy(false) + guard flush).

+//! Grant-listing hydration N+1 benchmark + user-flags herd (ROUND4).
+//!
+//! [1-3] After `list_incoming_grants`, the CalDAV calendar discovery,
+//! CardDAV book discovery and playlist listing each hydrated their K
+//! accessible resources with K SERIAL point SELECTs (one
+//! `WHERE id = $1` round-trip per resource, awaited in a loop) on every
+//! client sync poll / dashboard load. AFTER: one `WHERE id = ANY($1)`
+//! round-trip via the new `find_*_by_ids` batch methods — this bench
+//! drives the REAL repositories both ways (the single-get methods still
+//! exist for point lookups).
+//!
+//! [4] `get_user_flags` (called by the auth middleware on EVERY
+//! authenticated request) used a get→insert cache: on each 30 s TTL
+//! expiry, all in-flight requests of that user fired the SELECT
+//! concurrently. AFTER: `try_get_with` single-flight. The bench
+//! replicates both cache patterns around the real `UserPgRepository`
+//! query, herd-style.
+//!
+//! Equivalence gates: identical id sets from loop vs batch for all
+//! three resources; identical flags from every herd caller.
+//!
+//! Run (needs Postgres up; reads DATABASE_URL from .env):
+//!   cargo run --release --features bench --example bench_n1_hydration
+//! Tunables (env): BENCH_RESOURCES (15), BENCH_PASSES (200), BENCH_HERD (32).

+//! NC PROPFIND per-page enrichment — 3 serial round-trips vs `tokio::join!`.
+//!
+//! Every Depth:1 PROPFIND page on the NextCloud surface enriches its ≤500
+//! children with three INDEPENDENT batched reads: favorites
+//! (`user_favorites … = ANY`), oc:fileid resolution
+//! (`nextcloud_object_ids … = ANY`) and WebDAV dead properties
+//! (`webdav_dead_properties … = ANY`). The old code awaited them in
+//! sequence — 3×RTT per page; overlapping them costs ~max(RTT).
+//!
+//! Decide-by-bench (the round-7 deferred "serial pairs" item): round 6
+//! showed concurrency can LOSE on local-socket PG (authz `try_join_all`
+//! regressed), so this A/B carries an **injected-latency arm** — each
+//! round-trip is prefixed with `tokio::time::sleep(L)` to model network
+//! RTT at L = 0 / 0.25 / 1 / 5 ms. Adoption rule: `join!` must not
+//! regress at L=0 (the local-socket floor) and must win under injected
+//! RTT; the L=0 row is the rollback gate.
+//!
+//! The three queries are the production shapes bound over the same seeded
+//! 500-child page; the equivalence gate asserts both arms return
+//! identical favorite sets / id maps / dead-prop rows.
+//!
+//! Run (needs Postgres up; reads DATABASE_URL from .env):
+//!   cargo run --release --features bench --example bench_nc_enrich_join
+//! Tunables (env): BENCH_CHILDREN (500), BENCH_PASSES (100)

+//! NextCloud per-request session benchmark — deep-clone vs `Arc` end-to-end.
+//!
+//! Every authenticated NC request (all six DAV dispatchers + OCS) extracts
+//! the session. The old pipeline paid, per request:
+//!
+//!   • extractor: `(**arc).clone()` — a DEEP clone of `NcSession`
+//!     (`CurrentUser` 3 Strings + `raw_username` + chroot `FolderDto`
+//!     ~5 Strings ≈ 8-9 heap allocs) despite the doc claiming "one Arc
+//!     increment";
+//!   • chroot cache hit: moka `get` clones the stored `FolderDto` by value
+//!     (~5 more allocs) on the markerless (default-drive) branch;
+//!   • session build: `CurrentUser` built then cloned for the extension,
+//!     `raw_username` cloned, `user_id.to_string()` for the span.
+//!
+//! Round 9 stores `Arc<FolderDto>` in the cache, shares one
+//! `Arc<CurrentUser>` between the extension and the session, and extracts
+//! `SharedNcSession` (an `Arc` handle that derefs to `NcSession`).
+//!
+//! `mod before` replicates the old struct shapes + clone flows verbatim;
+//! equivalence gates assert every field consumed by handlers is identical.
+//!
+//! Sections:
+//!   1. Extractor — allocs/extract + ns/extract (BEFORE deep clone vs
+//!      AFTER production `SharedNcSession::from_request_parts`)
+//!   2. Chroot-cache hit — allocs/hit (FolderDto-by-value vs Arc)
+//!   3. Session build — allocs/build (double CurrentUser + clones vs
+//!      single shared Arc + moves)
+//!
+//! Run (no Postgres needed):
+//!   cargo run --release --features bench --example bench_nc_session
+//! Tunables (env): BENCH_REQS (100000)

+//! Photos timeline benchmark — full-library scan vs per-drive LATERAL top-N.
+//!
+//! `list_media_files` (file_blob_read_repository.rs) filters by
+//! `fi.drive_id IN (<grants subquery>)`, joins folders + file_metadata, and
+//! sorts globally by `media_sort_date DESC LIMIT k`. The doc comment claims
+//! `idx_files_media_timeline_by_drive` lets LIMIT stop the scan early, but
+//! the plan is a Nested Loop over the drive set feeding EVERY media row
+//! through a Hash Left Join into a top-N heapsort ABOVE the join — the
+//! index is drained to exhaustion on every page, so each timeline page
+//! costs O(library), not O(page).
+//!
+//! The AFTER shape materialises the accessible drive ids once, then does a
+//! `CROSS JOIN LATERAL (… ORDER BY media_sort_date DESC LIMIT k)` per drive
+//! — each LATERAL is one bounded index scan — and merges `drives × k` rows.
+//! The folders/file_metadata joins move OUTSIDE the top-N so only the k
+//! emitted rows pay them.
+//!
+//! Equivalence gate: page-by-page id sequences must be identical (the seed
+//! uses strictly distinct capture dates so ties cannot mask reordering).

+//! PROPFIND folder-listing pagination benchmark — LIMIT/OFFSET vs keyset.
+//!
+//! The streaming PROPFIND walker pages a folder's children 500 at a time in
+//! name order (`list_files_batch`). The old shape was `ORDER BY name LIMIT
+//! 500 OFFSET k` with no supporting index — every page bitmap-scanned all N
+//! children and top-sorted them, so a full folder walk was O(N²/500) row
+//! visits. The change adds `idx_files_folder_name (folder_id, name) WHERE
+//! NOT is_trashed` and switches the cursor to keyset (`name > $last`), making
+//! each page one O(page) index-range read.
+//!
+//! Modes (full walk of the folder, all pages):
+//!   OFFSET/no-idx — the true BEFORE (index dropped for the run)
+//!   OFFSET/idx    — index alone, old query shape
+//!   KEYSET/idx    — the AFTER
+//!
+//! Run (needs Postgres up; reads DATABASE_URL from .env):
+//!   cargo run --release --features bench --example bench_propfind_paging
+//! Tunables: BENCH_FILES (20000), BENCH_PAGE (500), BENCH_REPS (3)

+//! PROPFIND per-row XML emit benchmark — Vec churn + format-interpreter
+//! dates (ROUND4).
+//!
+//! For EVERY file/folder row of every PROPFIND page the old writers paid:
+//!   • a `partition` into two throwaway `Vec<&QualifiedName>`s (+ a third
+//!     for the 404 list) — even though the requested-props writer already
+//!     skips unknown names itself;
+//!   • `to_rfc3339()` + `to_rfc2822()` — chrono's format-spec interpreter
+//!     plus a heap String each;
+//!   • `size.to_string()` and a `format!("\"{etag}\"")`.
+//!
+//! AFTER: single-pass 404 computation (usually-empty Vec), stack-rendered
+//! dates/sizes (`common::fmt`, byte-identical, chrono fallback for
+//! out-of-range), exactly-sized etag quoting.
+//!
+//! The OLD writers are copied verbatim into `mod before`; the gate
+//! asserts byte-identical multistatus XML for named-prop (typical sync
+//! client set + unknown props), AllProp (with quota), and dead-prop
+//! carrying rows. Exit 1 on any diff.
+//!
+//! Run (no Postgres needed):
+//!   cargo run --release --features bench --example bench_propfind_xml
+//! Tunables (env): BENCH_ROWS (1000), BENCH_PASSES (200)

+//! Range-seek per-request authz duplication benchmark.
+//!
+//! `download_file_impl` calls `get_file_with_perms` once (authz + access
+//! notify + metadata) and THEN, in the Range branch, called
+//! `get_file_range_preloaded_with_perms` — which re-ran `require_file`
+//! (authz) + `notify_file_accessed` per request. Media players and PDF
+//! viewers fetch a file *exclusively* through Range requests: a `bytes=0-`
+//! probe then one request per seek. So every seek in a scrub re-authorized a
+//! file the request-level gate had already cleared.
+//!
+//! Round 7 drops the range branch to the non-perms `get_file_range_preloaded`
+//! (the share-landing and WebDAV range paths already do exactly this). This
+//! bench isolates the per-seek `require` that AFTER eliminates, driving the
+//! REAL `PgAclEngine`:
+//!   - WARM: the cache the initial `get_file_with_perms` warmed — each removed
+//!     seek-check was a moka hit + uuid parse (pure CPU/alloc).
+//!   - COLD: a shared-drive recipient whose drive-role cache expired mid-scrub
+//!     (30 s TTL) — each removed seek-check was a full drive-resolve query.
+//!
+//! Safety gate: the surviving request-level gate still authorizes correctly —
+//! the member is granted, a non-member is denied — so removing the per-seek
+//! re-check bypasses nothing.

+//! `/api/folders/{id}/resources` row→DTO mapping micro-alloc benchmark.
+//!
+//! The listing maps each `FolderResourceRow` into a `FolderResourceItemDto`.
+//! BEFORE cloned `row.name` into the DTO (`name: row.name.clone()`) even
+//! though the row is owned by the mapping closure — one avoidable `String`
+//! heap alloc per listed folder/file. AFTER computes the name-derived icon /
+//! category classes first (they borrow `&row.name`), then MOVES `row.name`
+//! into the DTO — the same output, one fewer alloc per row.
+//!
+//! Section 2 (round 9): the SAME clone-vs-move port applied to the
+//! favorites/recents listings (`/api/favorites/resources`,
+//! `/api/recent/resources`), which the round-7 rewrite never reached. Their
+//! per-row mapping additionally cloned `row.path` (owner rows) and
+//! `row.blob_hash` (file rows), so the saving is up to 3 allocs per file row.
+//! The two handlers share one mapping shape (only the `favorited_at` /
+//! `accessed_at` passthrough differs), so the favorites row stands for both.
+//!
+//! Run:
+//!   cargo run --release --features bench --example bench_resource_row_map
+//! Tunables (env): BENCH_ROWS (500).

+//!   3. NC PROPFIND per-row integer props (`oc:fileid`, `nc:creation_time`,
+//!      `nc:upload_time`): BEFORE `to_string()` per field vs AFTER
+//!      `common::fmt` stack render. Gate: byte-identical XML.
+//!   4. NC trashbin date/int props: BEFORE `to_rfc2822()` + `to_string()`
+//!      vs AFTER stack render. Gate: byte-identical XML.
+//!   5. Native-WebDAV scope prefix test: BEFORE `format!("{prefix}/")` per

+//!   6. Share listing base-url: BEFORE `env::var("OXICLOUD_BASE_URL")` +
+//!      rebuild per row vs AFTER the construction-time snapshot.
+//!   7. JWT verify miss: BEFORE fresh `Validation` + `DecodingKey` per
+//!      decode vs AFTER pre-built fields. Gate: identical claims.
+//!   8. AES-GCM cipher hand-off: BEFORE key-schedule memcpy clone vs AFTER

+//! Round-10 query-shape pack — BEFORE/AFTER over the dev Postgres.
+//!
+//! Sections:
+//!   1. Share-download metadata: BEFORE 2× `get_file` per download (the
+//!      handler fetched the DTO, then `get_file_optimized` re-fetched it)
+//!      vs AFTER 1× + `_preloaded`. Gate: identical DTOs.
+//!   2. CalDAV update/delete authz gate: BEFORE full `find_event_by_id`
+//!      (drags `ical_data`) vs AFTER `find_calendar_id_by_event_id` scalar.
+//!      Gate: identical calendar id.
+//!   3. Contact-group summary: BEFORE `get_contacts_in_group().len()`
+//!      (hydrates vCard TEXT + 3 JSONB parses × N) vs AFTER
+//!      `count_contacts_in_group`. Gate: identical count.
+//!   4. Trash listing: `drive_id = ANY($1) AND is_trashed` with only the
+//!      pre-round indexes vs the new partial `(drive_id, trashed_at) WHERE
+//!      is_trashed` pair. Gate: identical row sets.
+//!   5. Legacy favorites listing rows: BEFORE `::TEXT` server casts vs
+//!      AFTER binary UUID decode + app-side render (the shipped SQL).
+//!      Gate: identical rendered tuples.
+//!   6. `save_faces`: BEFORE one INSERT per face (replica of the old loop)
+//!      vs AFTER the shipped single UNNEST INSERT. Gate: identical rows.
+//!   7. Playlist reorder: BEFORE one UPDATE per track vs AFTER the shipped
+//!      UNNEST UPDATE. Gate: identical final positions.
+//!   8. Search page: BEFORE serial file-page + folder queries vs AFTER
+//!      `tokio::join!` (the shipped shape; the content-index arm is off in
+//!      this harness — the overlap win measured is files∥folders).
+//!      Gate: identical results.
+//!   9. Move pre-check: BEFORE serial src-drive + dst-drive point reads vs
+//!      AFTER `join!`. Gate: identical resolutions. Decide-by-bench.
+//!
+//! Run (needs Postgres; reads DATABASE_URL from .env):
+//!   cargo run --release --features bench --example bench_round10_queries
+//! Tunables (env): BENCH_PASSES (200)

+//! Round-11 CPU/alloc micro-pack — BEFORE replicas vs AFTER shapes.
+//!
+//! Same discipline as ROUND2-10: every section measures a byte-faithful
+//! replica of the shipped code (BEFORE) against the candidate shape
+//! (AFTER), with an equivalence gate. An AFTER that doesn't win gets
+//! rolled back instead of adopted.
+//!
+//! Sections (all pure CPU, no Postgres):
+//!    1. REST download `FileDto` dead clone vs mime/size capture + move
+//!    2. Single-resource GET/HEAD `Last-Modified`: chrono `to_rfc2822()`
+//!       vs `common::fmt::rfc2822_utc` stack render (gate: byte-identical).
+//!       VERDICT: header port REJECTED — the chrono String is already the
+//!       terminal allocation; only body-emit sites benefit.
+//!    3. `/status.php` poll: rebuild `json!` + serialize vs `OnceLock<Bytes>`
+//!       (gate: byte-identical)
+//!    4. NC chunk-upload session PROPFIND: `push_str(&format!)` + chrono
+//!       per chunk vs `with_capacity` + `write!` + stack dates
+//!       (gate: byte-identical XML)
+//!    5. RateLimiter: 2 key allocs + entry+insert vs (a) `and_upsert_with`
+//!       [REJECTED: slower + more allocs] vs (b) lock-free get + insert
+//!       [ADOPTED] (gate: identical counter sequences)
+//!    6. CSRF header token: `to_string` vs borrow compare (gate: same bool)
+//!    7. Thumbnail ETag: `{:?}` Debug enums vs `as_str` + push (gate: bytes)
+//!    8. Recent-handler id: `Uuid::to_string` vs stack `encode_lower`
+//!       (gate: identical str)
+//!    9. 4xx error body: status+message clones + `kind.to_string()` vs
+//!       borrowed single-alloc serialize (gate: byte-identical JSON)
+//!   10. vCard emit: `push_str(&format!)` vs `write!` (gate: bytes)
+//!   11. Search page slice: `.to_vec()` clone vs `drain` move (gate: equal)
+//!   12. Content-hit verify: double `Uuid::parse_str` vs parse-once pairs
+//!       (gate: same verified set)
+//!   13. Group last-user check: O(N·M) slice contains vs HashSet
+//!       (gate: same bool)
+//!   14. Retry op label: eager `format!` vs lazy closure (success path)
+//!   15. `encrypt_bytes`: ciphertext alloc + copy vs in-place detached
+//!       (gate: byte-identical output for a fixed nonce + round-trip)
+//!   16. Encrypted `collect_stream`: `Vec::new()` growth vs pre-sized
+//!       (gate: same bytes)
+//!   17. Face clustering `cosine`: per-pair norm recompute vs precomputed
+//!       sqrt norms (gate: bitwise-identical similarity + same unions)
+//!   18. `/openapi.json`: rebuild + serialize vs `OnceLock<Bytes>`
+//!       (gate: byte-identical)
+//!   19. `CalendarEventDto::from`: getter clones (incl. the ~11 KB
+//!       `ical_data`) vs `into_parts` move (gate: identical DTO fields)
+//!   20. `StoragePath` row materialization: eager `Vec<String>` segments +
+//!       duplicated `path_string` vs single canonical joined `String`
+//!       (gate: identical path/file_name/parent/Display)
+//!
+//! Run: cargo run --release --features bench --example bench_round11_micro

+//! Round-11 query-shape pack — BEFORE query shapes vs AFTER (needs Postgres).
+//!
+//! Sections:
+//!   1. Deferred upload registration (the default REST upload path):
+//!      3 round-trips (parent drive SELECT → INSERT → parent path SELECT,
+//!      the middle two re-reading the SAME folders row) vs the single
+//!      `WITH parent AS (…) INSERT … RETURNING` template `persist_file`
+//!      already uses. Gate: identical returned (path, drive) + identical
+//!      not-found semantics for a missing parent.
+//!   2. Calendar/AddressBook/Playlist authz: the only `check()` arms with
+//!      no result cache — `role_grants` point query per check vs a moka
+//!      `direct_grant_cache` hit. Gate: same verdict + revocation flip
+//!      after invalidate.
+//!   3. `expand_user` cache miss: `is_external` + recursive groups CTE
+//!      awaited serially vs `tokio::join!`. Gate: same result set.
+//!   4. Places geo clusters: `min(fm.file_id::text)` (casts every row)
+//!      vs `min(fm.file_id)::text` (one cast per cluster). Gate:
+//!      identical cluster rows (uuid byte order == canonical text order).
+//!   5. Recluster persistence: F sequential `assign_person` UPDATEs vs
+//!      one `UPDATE … FROM unnest($1,$2)` batch. Gate: identical final
+//!      `person_id` column state.
+//!
+//! Run (needs Postgres; reads DATABASE_URL from .env):
+//!   cargo run --release --features bench --example bench_round11_queries
+//! Tunables (env): BENCH_PASSES (200)

+//!   [1] Listing JSON serialization — axum `Json`'s 128-byte `BytesMut`
+//!       seed + doubling-realloc chain vs a pre-sized `Vec` +
+//!       `serde_json::to_writer` (the `sized_json` helper).
+//!   [2] Dynamic-compression predicate — the ~28-node `And` chain (each
+//!       `NotForContentType` re-reading + re-validating the Content-Type
+//!       header) vs a single-pass policy node.
+//!   [3] Security-header stack — 4 `SetResponseHeaderLayer`s wrapping the
+//!       CSP middleware (5 tower layers) vs the headers folded into the
+//!       CSP pass (1 layer).
+//!   [4] Media capture-metadata extraction — the 2-3 opens per image /
+//!       2 per video (kamadak full read + nom-exif path re-reads) vs the
+//!       single-read shape (nom-exif fed from the in-RAM bytes,
+//!       one `MediaParser`, kind-dispatched videos).
+//!   [5] Chunked-upload session map — 2 (prepare) + 3 (commit) DashMap
+//!       lookups per chunk plus 2 `Uuid::to_string` allocs vs fused
+//!       owner-check lookups + stack-encoded uuid compare.
+//!
+//! Run:

+//! Round-12 query-shape pack (needs the dev Postgres up; reads DATABASE_URL
+//! from `.env`).
+//!
+//! Six sections, each BEFORE (verbatim replica of the shipped query shape)
+//! vs AFTER (proposed shape), with equivalence/safety gates:
+//!
+//!   [1] NC sharee search — the wide 21-column `search_users` row (incl. the
+//!       up-to-512 KiB avatar `image`) fetched per match when the handler
+//!       only reads `username`, vs a narrow username-only SELECT; plus a
+//!       `gin_trgm_ops` index arm for the leading-wildcard ILIKE.
+//!   [2] Password login — the redundant full-row `update_user` (17 columns
+//!       incl. `image`) that `create_session`'s own `last_login_at` UPDATE
+//!       immediately overwrites, vs create_session alone.
+//!   [3] Email-verified stamp (magic-link / OIDC JIT) — full-row
+//!       `update_user` to set one timestamp vs a narrow conditional UPDATE.
+//!   [4] Refresh-token rotation — revoke txn + create txn (2 transactions,
+//!       6 statements) vs one fused rotation transaction.
+//!   [5] WOPI CheckFileInfo — require(Read) → get_file → check(Update)
+//!       serial vs `tokio::join!` (real `PgAclEngine` + real file read repo;
+//!       cold and warm arms).
+//!   [6] Upload quota pair — user-envelope + drive-cap checks as two serial
+//!       point reads vs one fused SELECT (verdict precedence preserved).
+//!

+//! Round-13 HTTP micro-pack (no Postgres).
+//!
+//! Two sections, each BEFORE (verbatim replica of the shipped shape) vs
+//! AFTER (proposed shape), with byte-identity / equivalence gates:
+//!
+//!   [H1] Duplicate `TraceLayer` on `/api` — the inner
+//!        `TraceLayer::new_for_http()` in `routes.rs` sat under the global
+//!        `TraceLayer + ClientIpMakeSpan` stack in `main.rs`, so every
+//!        `/api` request was wrapped in TWO span/response-future layers.
+//!        Measured end-to-end through real axum routers, one stack vs two.
+//!   [H2] Per-request `client_ip` `String` in the span factory —
+//!        `ClientIpMakeSpan::make_span` allocated an owned `String` on every
+//!        request purely to feed the span's `%client_ip` Display, vs a
+//!        borrow-only `ClientIpDisplay` that renders into the span storage.
+//!
+//! Run:
+//!   cargo run --release --features bench --example bench_round13_micro

+//! Round-14 query-shape pack (needs the dev Postgres up; reads DATABASE_URL
+//! from `.env`).
+//!
+//! Each section is BEFORE (verbatim replica of the shipped query shape) vs
+//! AFTER (proposed shape), with an equivalence/safety gate and a `GATE FAIL`
+//! rollback check — an AFTER that doesn't beat its BEFORE exits non-zero.
+//!
+//!   [Q1] Lightbox face boxes — `faces_for_file`'s 10-column row (incl. the
+//!        2,048-byte `embedding` BYTEA, decoded into a `Vec<f32>` per face)
+//!        hydrated for a group photo, then filtered `user_id == caller` in
+//!        Rust, vs a narrow `SELECT id, person_id, bbox … WHERE file_id = $1
+//!        AND user_id = $2` (embedding + 6 unused columns dropped; the caller
+//!        filter pushed into SQL). The only consumer, `people_service::
+//!        faces_for_file`, builds `FaceBoxDto { id, person_id, x,y,w,h }`.

+//! Round-15 tantivy zero-hit snippet skip (no Postgres).
+//!
+//! `TantivyContentIndex::search_blocking` builds a `SnippetGenerator` from the
+//! query right after the `TopDocs` search — but a `SnippetGenerator::create`
+//! compiles the query against the index (term lookups + weight build), and when
+//! the query matched NO documents that generator is never used (the per-hit
+//! loop is empty). The shipped fix returns `Ok(Vec::new())` as soon as
+//! `top_docs.is_empty()`, before the create.
+//!
+//! This bench reproduces the exact skipped operation on a RAM index built with
+//! the public tantivy API (same crate + version the service uses):
+//!   BEFORE = search (→ 0 hits) + `SnippetGenerator::create` (+ `set_max_num_chars`)
+//!   AFTER  = search (→ 0 hits) + `top_docs.is_empty()` early return
+//! The delta is the wasted create the fix removes from every no-hit content
+//! search. A sanity arm confirms a term that DOES hit still yields a snippet, so
+//! the skip only ever triggers on a genuine zero-hit query.
+//!
+//! Run:
+//!   cargo run --release --features bench --example bench_round15_tantivy

+//! Round-17 dedup + CardDAV CPU/alloc micro-pack (no Postgres).
+//!
+//! Same rule as ROUND2–16: each section is BEFORE (verbatim replica of the
+//! shipped-before shape) vs AFTER (verbatim replica of the shipped-after shape,
+//! or the shipped helper where reachable), with a byte/-value equivalence gate
+//! and a `GATE FAIL … rollback` check that exits non-zero if the AFTER arm
+//! fails to reduce allocations — the round's roll-back rule encoded into the
+//! benchmark.
+//!
+//!   [D1] `DedupService::hash_chunk_sequence` (delta-commit verification) took
+//!        `chunks: &[(String, u64)]` and fed the backend stream via
+//!        `chunks.iter().cloned()` — re-allocating every chunk-hash String a
+//!        second time, on top of the owned `Vec` the caller already built with
+//!        `c.h.clone()`. Taking the `Vec` by value and `into_iter()`-ing it
+//!        moves those Strings in: zero internal clones.
+//!   [D2] The chunk-ingest loop (`store_from_stream`) allocated the 64-char hex
+//!        hash String THREE times per chunk: `to_hex().to_string()`, then
+//!        `chunk_hashes.push(hash.clone())`, then `session_seen.insert(hash
+//!        .clone())` — the last dropped immediately on a duplicate. Keying the
+//!        intra-upload dedup set on the raw 32-byte BLAKE3 digest (`[u8; 32]`,
+//!        `Copy`, no heap) drops the set clone entirely, and moving the hex into
+//!        `chunk_hashes` on the duplicate branch drops the manifest clone there:
+//!        3 → 2 allocs (new chunk) / 3 → 1 (duplicate), on the hottest write
+//!        path in the dedup system.
+//!   [V1] `contact_to_vcard` emitted every EMAIL/TEL/ADR `TYPE=` token via
+//!        `ty.to_uppercase()` — one throw-away String per token per vCard. The
+//!        `push_upper` helper writes the upper-cased chars straight into the
+//!        vCard buffer: zero temporaries.
+//!
+//! Run:
+//!   cargo run --release --features bench --example bench_round17_micro
+//! Tunables (env): BENCH_ITERS (100000), BENCH_CHUNKS (64), BENCH_DUP_RATIO (2)

+//! shape), with a byte-for-byte equivalence gate and a `GATE FAIL … rollback`
+//! check that exits non-zero if the AFTER arm fails to reduce allocations — the

+//!
+//!   [C1] `CalendarEvent::update_ical_property` / `remove_ical_property`
+//!        rewrote the ENTIRE `ical_data` body with `format!("{}{}{}")` on every
+//!        call, and allocated TWO search needles per call (`\nNAME:` and the
+//!        redundant `\r\nNAME:` — the CRLF form can never match where the LF
+//!        form doesn't, since `\nNAME:` is its suffix). Because
+//!        `calendar_storage_adapter::update_event` applies each changed field
+//!        independently, a multi-field REST edit paid one full-body (up to
+//!        ~11 KB) String allocation PER changed property, plus two needles.
+//!        The shipped-after form mutates the body in place (`replace_range` for
+//!        an existing property, four `insert`/`insert_str` for a new one) and
+//!        builds the single `\nNAME:` needle on the stack — zero heap needle,
+//!        no fresh-body allocation. The edited spans are byte-for-byte the same
+//!        the `format!` reconstruction produced (`replace_range(a..b, v)` ≡
+//!        `before + v + after`), so the emitted body is identical — including

+//!   [M1] `AppPasswordService::verify_basic_auth` builds the moka cache key as

+//!        Basic-auth DAV/CalDAV/CardDAV/NextCloud request (before the cache
+//!        lookup, so even cache hits pay it). The `format!` heap-allocates one
+//!        throw-away `String` per request purely to feed bytes to blake3. The
+//!        shipped-after form streams the same bytes into an incremental
+//!        `blake3::Hasher` — byte-identical 32-byte key, zero allocation.
+//!
+//!   [M2] `WopiTokenService::validate_token` / `generate_token` rebuilt a

+//!        `algorithms` Vec) and a `DecodingKey`/`EncodingKey` (copies the secret

+//!        poll these continuously. The shipped-after form prebuilds all three as
+//!        struct fields in `new()` (exactly what `JwtTokenService` already does).

+//!          - FN fallback `format!("{first} {last}").trim().to_string()` dropped
+//!            the throwaway `.to_string()` copy (writes the borrowed trim slice);
+//!          - NOTE `notes.replace('\n', "\\n")` allocated a full copy even when
+//!            the note has no newline — now guarded (`contains('\n')`), the
+//!            common no-newline note writes the borrowed slice directly;
+//!          - REV `updated_at.format("%Y%m%dT%H%M%SZ")` ran chrono's strftime

+//!   [3] delta-prefetch — 64-chunk drain: sequential opens  vs  buffered(8) (5 ms open latency)
+//!   [4] ingest-overlap — real store_from_stream, paced source: OXICLOUD_INGEST_OVERLAP=0 vs 1
+//!   [5] zip-stream     — time-to-first-byte: temp-file build  vs  duplex streaming

+//! Round-20 CPU/alloc micro-pack (no Postgres).
+//!
+//! Same rule as ROUND2–19: each section is BEFORE (verbatim replica of the
+//! shipped-before shape) vs AFTER (verbatim replica of the shipped-after shape,
+//! which the source is then made to match), with a byte/-value equivalence gate
+//! and a `GATE FAIL … rollback` check that `std::process::exit(1)`s if the AFTER
+//! arm fails to beat its BEFORE — the round's roll-back rule encoded into the
+//! benchmark. An AFTER that doesn't win is never applied to the source.
+//!
+//!   [A1] `CalendarEvent::prop_with_params` builds a throwaway
+//!        `HashMap<String, Vec<String>>` (uppercased keys + cloned value Vecs)
+//!        per DTSTART/DTEND/RECURRENCE-ID on every CalDAV PUT / iCal import,
+//!        though the 5 production call sites only read `.get("VALUE")` (all-day
+//!        detect) or discard the map entirely. AFTER scans `prop.params` for a
+//!        case-insensitive `VALUE=DATE` directly — same bool, zero map.
+//!
+//!   [A2] `UserDto::from(User)` takes the `User` BY VALUE yet clones every
+//!        field through its accessors — including `image` (a data URI up to
+//!        512 KiB) and `ui_preferences` (a full `serde_json::Value` tree) — on
+//!        every `/api/auth/me` and admin user listing. AFTER moves the owned
+//!        fields out (the `into_parts` treatment File/Folder/Contact already
+//!        have), keeping the DTO byte-identical.
+//!
+//!   [A3] `ContactService::parse_vcard` collects `vcard_data.lines()` into a
+//!        `Vec` it only iterates, and runs `line.to_ascii_uppercase()` — a full
+//!        per-line `String` copy — per EMAIL/TEL/ADR line just to `.contains`
+//!        a `TYPE=` token, on every CardDAV PUT / vCard import. AFTER iterates
+//!        `lines()` directly and matches with the allocation-free
+//!        `common::text::ascii_ci_contains` (the CalDAV parse path already uses
+//!        this shape).
+//!
+//!   [A4] `CalendarDto::from(Calendar)` / `AddressBookDto::from(AddressBook)`
+//!        consume the entity yet clone `name`/`description`/`color` and (for
+//!        calendars) the whole `custom_properties` `HashMap<String,String>`, on
+//!        every CalDAV/CardDAV discovery listing. AFTER moves them.
+//!
+//!   [I1] The listing repositories map rows with
+//!        `.collect::<Result<Vec<T>, E>>()`, whose `Result`-shunt reports
+//!        `size_hint().0 == 0` — so the `Vec` grows from capacity 0 with
+//!        ~⌈log₂N⌉ reallocations, memcpy-ing the accumulated (File-sized)
+//!        elements each grow. AFTER pre-sizes with `Vec::with_capacity(rows.len())`
+//!        and pushes with `?` (the exact pattern `list_media_files` already uses).
+//!
+//!   [I4] `encrypted_blob_backend::plaintext_stream` `.collect()`s every
+//!        emit-slice into a `Vec` before `stream::iter` — an eager container of
+//!        ⌈len/64 KiB⌉ entries per encrypted read. AFTER hands the lazy `map`
+//!        iterator to `stream::iter` directly (same slice sequence, no Vec).
+//!
+//! Run:
+//!   cargo run --release --features bench --example bench_round20_micro

+//! Round-21 CPU/alloc micro-pack (no Postgres).
+//!
+//! Same rule as ROUND2–20: each section is BEFORE (verbatim replica of the
+//! shipped-before shape) vs AFTER (verbatim replica of the shipped-after shape,
+//! which the source is then made to match), with a byte/-value equivalence gate
+//! and a `GATE FAIL … rollback` check that `std::process::exit(1)`s if the AFTER
+//! arm fails to beat its BEFORE — the round's roll-back rule encoded into the
+//! benchmark. An AFTER that doesn't win is never applied to the source.
+//!
+//!   [R1] The CalDAV/CardDAV row-mapping repositories build their result Vec
+//!        with `let mut v = Vec::new(); for row in rows { v.push(map(row)?) }`,
+//!        growing the container from capacity 0 (~⌈log₂N⌉ reallocations, each
+//!        memcpy-ing the accumulated rows). AFTER pre-sizes with
+//!        `Vec::with_capacity(rows.len())` — the file-side sibling ROUND20 §I1
+//!        shipped, extended to the calendar/contact repos it deferred.
+//!
+//!   [R2] `DedupService::settle_batch` cloned every 64-char chunk hash into a
+//!        `Vec<String>` purely to `.bind()` it to the pin `UPDATE … = ANY($1)`.
+//!        AFTER binds a borrowed `Vec<&str>` — sqlx encodes `&[&str]` to
+//!        `text[]` identically (favorites_pg_repository.rs:271 already does
+//!        this), so the per-chunk hash `String` disappears.
+//!
+//!   [R3] `DedupService::store_loose_chunks` (the delta-upload sibling of the
+//!        ROUND17 §D2 ingest loop) kept an intra-request dedup `HashSet<String>`
+//!        and cloned the hex hash TWICE per frame (into `received` and into the
+//!        set). AFTER keys the set on the raw `[u8; 32]` BLAKE3 digest (`Copy`,
+//!        no heap key) and moves the hex into `received` on a duplicate.
+//!
+//!   [R4] `carddav_adapter::write_contact_response` built a `"…"`-quoted
+//!        `String` for `getetag` then wrote it auto-escaped (quick_xml escapes
+//!        the `"` → `&quot;`, re-allocating). AFTER emits the two quotes as
+//!        borrowed pre-escaped `&quot;` text events (the NextCloud ROUND20 §C1
+//!        pattern applied to the CardDAV emitter it missed).
+//!
+//!   [R5] `contact_to_vcard` stamped `BDAY` via `write!(…, "{}",
+//!        bday.format("%Y-%m-%d"))`, running chrono's strftime interpreter per
+//!        contact-with-birthday. AFTER renders the fixed `YYYY-MM-DD` on the
+//!        stack via `fmt::compact_date` (the date-only companion to the §V2 REV
+//!        renderer), with the chrono fallback for out-of-range years.
+//!
+//!   [R6] The NextCloud trashbin PROPFIND row set `d:getcontenttype` for a
+//!        folder to `"httpd/unix-directory".to_string()` — a heap String for a
+//!        static constant, per trashed folder row. AFTER borrows it via
+//!        `Cow::Borrowed` (the ROUND16 §M1 `Cow<'static, str>` pattern).
+//!
+//! Run:
+//!   cargo run --release --features bench --example bench_round21_micro

+//! Round-22 CPU/alloc micro-pack (no Postgres).
+//!
+//! Same rule as ROUND2–21: each section is BEFORE (verbatim replica of the
+//! shipped-before shape) vs AFTER (verbatim replica of the shipped-after shape,
+//! which the source is then made to match), with a byte/-value equivalence gate
+//! and a `GATE FAIL … rollback` check that `std::process::exit(1)`s if the AFTER
+//! arm fails to beat its BEFORE — the round's roll-back rule encoded into the
+//! benchmark. An AFTER that doesn't win is never applied to the source.
+//!
+//!   [H1] Hot GET handlers (`get_thumbnail`, `download_file`, `list_files`,
+//!        `list_photos`, NC `preview`, public-share download/access) took the
+//!        axum `HeaderMap` extractor, which does `parts.headers.clone()` — an
+//!        owned clone of the whole request header table (~2 allocs) — just to
+//!        read 1–3 headers. AFTER takes `req: Request` and reads `req.headers()`
+//!        by borrow (the ROUND14 §A4 middleware pattern applied to the handlers).
+//!
+//!   [W1] The native WebDAV `write_etag_quoted` (per file AND per folder of
+//!        every `/webdav/` PROPFIND row, up to 500/page — the most-travelled
+//!        DAV path) built a `"{etag}"` String then wrote it auto-escaped;
+//!        `quick_xml` escapes the `"` → `&quot;`, re-allocating an owned `Cow`,
+//!        so 2 allocs/row (buffer + escape). AFTER emits the quotes as borrowed
+//!        pre-escaped `&quot;` events (the ROUND20 §C1 / ROUND21 §R4 pattern).
+//!
+//!   [C1] The CalDAV `getetag` emit (per event of every calendar REPORT/multiget,
+//!        per calendar of the home-set PROPFIND) still escaped a `"…"` value
+//!        (reused buffer → 1 alloc/event escape; `format!` calendar sites → 2).
+//!        AFTER routes all five sites through a `write_quoted_etag` helper
+//!        (borrowed pre-escaped quotes) — 0 allocs.
+//!
+//!   [D1] `FileDto::from` cloned `content_hash` via `file.content_hash()
+//!        .to_string()` and then `into_parts()` MOVED the same `blob_hash` into
+//!        `parts.blob_hash`, which was dropped unused — 1 wasted alloc on every
+//!        listing row. AFTER reuses `parts.blob_hash` (0).
+//!
+//!   [E1] `CalendarEvent::update_time_range` / `update_all_day` stamped timed
+//!        DTSTART/DTEND via `format!("{}", t.format("%Y%m%dT%H%M%SZ"))` — chrono's
+//!        strftime interpreter (~3 allocs). AFTER stack-renders via the shipped
+//!        `fmt::compact_ical_utc` and passes the `&str` straight to
+//!        `update_ical_property` (0 allocs), chrono fallback out of range.
+//!
+//!   [S1] `ShareItemType::try_from` matched `s.to_lowercase().as_str()` — a
+//!        throwaway Unicode-lowercased String — against two ASCII literals.
+//!        AFTER uses `eq_ignore_ascii_case` (byte-identical acceptance, 0 allocs).
+//!
+//! Run:
+//!   cargo run --release --features bench --example bench_round22_micro
+//! Tunables (env): BENCH_ITERS (200000)

+//! equivalence evidence lives in `bench_round23_queries.rs`.
+//!
+//! Same rule as ROUND2–22: each section is BEFORE (verbatim replica of the
+//! shipped-before shape) vs AFTER (verbatim replica of the shipped-after shape,
+//! which the source is then made to match), with a byte/-value equivalence gate
+//! and a `GATE FAIL … rollback` check that `std::process::exit(1)`s if the AFTER
+//! arm fails to beat its BEFORE.

+//!        + `serde_json::from_value::<Vec<Dto>>` — a throwaway `Value` DOM per
+//!        column, walked a second time. AFTER decodes straight into the typed
+//!        Vec via `sqlx::types::Json<T>` (one `from_slice` pass). Modeled here
+//!        as `from_slice::<Value>` + `from_value` vs `from_slice::<Vec<Dto>>`.
+//!
+//!   [J2] `DrivePolicies::from_value` did `serde_json::from_value(value.clone())`
+//!        — cloning the ENTIRE policies DOM per drive-policy read. AFTER
+//!        deserializes from the borrow (`T::deserialize(&Value)`), no clone.
+//!
+//!   [U1] `dedup_service` (`store_loose_chunks` final registration + the ingest

+//!        out of an owned, dead-after `Vec<(String,i64)>` purely to reshape for

+//! Round-23 PostgreSQL query-shape pack — end-to-end latency + equivalence on
+//! the live dev Postgres. The deterministic alloc gates for the decode/clone
+//! candidates live in `bench_round23_micro.rs`; this harness measures the real
+//! round-trip / decode wins against seeded fixtures and asserts identical
+//! results (the equivalence gate — a mismatch `std::process::exit(1)`s).
+//!
+//!   [Q1] Contact JSONB decode on REAL rows (contact_pg §J1): fetch a seeded
+//!        address book's contacts once, then decode the `email`/`phone`/`address`
+//!        JSONB columns BEFORE (`row.get::<Value>` + `from_value`) vs AFTER
+//!        (`row.try_get::<sqlx::types::Json<Vec<Dto>>>`). Gate: identical decode.
+//!
+//!   [Q4] `get_user_profile` (§P1): two independent point reads of the caller +
+//!        target users, BEFORE serial (`await` then `await`) vs AFTER concurrent
+//!        (`tokio::join!`). Gate: identical rows.
+//!
+//!   [Q6] `subject_group::remove_member` (§G1): the child group's transitive
+//!        user set (a recursive CTE) BEFORE computed TWICE (the shipped-before
+//!        pre-check + `invalidation_targets`) vs AFTER once + reused. Gate:
+//!        identical user set.
+//!
+//! Run (needs the dev Postgres up; reads DATABASE_URL from .env):
+//!   cargo run --release --features bench --example bench_round23_queries
+//! Tunables (env): BENCH_PASSES (200), Q1_CONTACTS (500), Q1_DECODE_PASSES (4000)

+//! Round-24 — `download_zip` per-item authz+metadata N+1 → batch, VALIDATED.
+//!
+//! `BatchOperations::download_zip` authorized + fetched each selected file with
+//! a per-file `get_file_with_perms` (= `require_file` authz + `get_file`) — 2
+//! serial round-trips per file, before any streaming. AFTER routes the whole
+//! multi-select through `FileRetrievalService::get_files_by_ids_with_perms`,
+//! which authorizes every id in ONE `check_files_read_batch` and fetches the
+//! authorized ids in ONE `get_files_by_ids` (2 round-trips total). The
+//! subsequent `add_file_entry_streamed` keeps its own per-file stream-open Read
+//! check + Recents recording (now a primed-cache hit), so authorization still
+//! happens BEFORE any ZIP entry is written — a denied file never leaks its name.
+//!
+//! Because this change is authorization-sensitive, the gate is the security
+//! property itself: the batch `check_files_read_batch` must make the EXACT same
+//! per-file inclusion decision as the shipped-before per-file `require` loop —
+//! same **set** AND same **input order** — over a mix of
+//!   • files on a drive the caller is granted `editor` on   (INCLUDED)
+//!   • files on a drive the caller has NO grant on          (DENIED)
+//!   • ids that don't exist at all                          (MISSING)
+//! and the batch fetch must return exactly the authorized, existing files.
+//! Any divergence `std::process::exit(1)`s.
+//!
+//! Drives the REAL `PgAclEngine` + `FileBlobReadRepository` (the fresh_engine
+//! shape from bench_favorites_authz).
+//!
+//! Run (needs Postgres up; reads DATABASE_URL from .env):
+//!   cargo run --release --features bench --example bench_round24_zip_authz

+//!        doc comment — but `let mut ciphertext = encrypted.split_off(NONCE_SIZE)`
+//!        allocates a fresh `Vec` and memcpy's the ENTIRE ciphertext+tag (~1 MiB
+//!        per CDC chunk, up to a whole legacy blob) on every decrypted read.
+//!        ROUND11 §15 fixed only the encrypt side. AFTER copies the 12-byte nonce
+//!        and 16-byte tag to the stack, decrypts the middle in place via
+//!        `decrypt_in_place_detached`, and returns a zero-copy `Bytes::slice`
+//!        past the nonce — 0 extra allocations, 0 full-payload memcpy. The RAM
+//!        win is in BYTES: peak drops from ~2× to ~1× the payload.
+//!
+//!   [M2] Delta commit (`delta_upload_service::commit_with_perms`) materializes
+//!        the per-occurrence chunk-hash list a THIRD time at the manifest bind
+//!        (`request.chunks.iter().map(|c| c.h.clone()).collect()`), even though
+//!        `request.chunks` is owned and dead after that line. AFTER move-unzips
+//!        (`request.chunks.into_iter().map(|c| (c.h, c.s)).unzip()`) — N 64-byte
+//!        hash-String clones → 0.
+//!
+//!   [M3] `folder_handler::download_folder_zip{,_impl}` binds a
+//!        `Query<HashMap<String, String>>` as `_params` and discards it — pure
+//!        dead work: axum parses the whole query string into a `HashMap` + one
+//!        owned `String` key and value per param, all dropped unread. AFTER
+//!        removes the extractor (byte-identical response; the handler only reads
+//!        the path `id`).

+//! Round-25 PostgreSQL query-shape pack — end-to-end round-trips + wall on the

+//!
+//!   [Q1] `music_storage_adapter::list_public_playlists` is 1 + N round-trips:
+//!        one listing SELECT then one `SELECT COUNT(*) FROM audio.playlist_items`
+//!        per returned playlist (up to 101 at limit=100). AFTER folds the count
+//!        into the listing with a `LEFT JOIN … GROUP BY` — one round-trip.
+//!        Gate: AFTER wall < BEFORE wall AND identical (playlist → track_count).
+//!
+//!   [Q2] The three REST contact listings `SELECT … vcard …` — the multi-KB
+//!        vCard TEXT (may embed a base64 PHOTO) — but every caller maps
+//!        Contact → ContactDto, which has NO vcard field, so it is fetched,
+//!        shipped over the wire, decoded into a String and dropped. AFTER omits
+//!        the vcard column (a lite mapper passes an empty string). Gate: AFTER
+//!        wall < BEFORE wall AND identical (id, full_name, photo_url) DTO fields.

+//! Round-26 disk-I/O pack (no Postgres) — async wall on a tmpfs-backed tempdir.

+//!        `{00..ff}` shard dirs (the line-122 comment claims otherwise), so each
+//!        of the three cache-write sites re-runs `tokio::fs::create_dir_all(parent)`
+//!        on the hot path — a wasted `mkdirat(EEXIST)` + component stat + a

+//!        AFTER pre-creates the shard dirs at init (mirroring
+//!        `LocalBlobBackend::initialize`) and drops the per-write call. Gate:
+//!        AFTER wall (per write) strictly lower than BEFORE (the redundant
+//!        create_dir_all).
+//!
+//!   [D2] TESTED AND REVERTED — see benches/ROUND26.md. Moving the moka
+//!        eviction-listener unlink off the reactor via `spawn_blocking` was
+//!        refuted by the benchmark: on the local cache dir (fast unlink ~7 µs)
+//!        the `spawn_blocking` dispatch (~20 µs) costs MORE on the reactor than
+//!        the inline `std::fs::remove_file` it replaces. The original inline

+//!   [A] NextCloud REPORT emit loops (`report_handler`) still build each row's

+//!       (webdav_handler.rs child loop). AFTER mirrors that: `nc_href_into`
+//!       writes into one reused buffer with a precomputed `encoded_user`.
+//!

+//!       Tier 1 and `get_file_range_preloaded` — the video-scrub hot path) builds
+//!       the owned `get_or_load` args (`format!("\"{}\"", hash)` etag, the
+//!       `hash.to_string()` key, `id.to_string()`) BEFORE the cache is probed.
+//!       `get_or_load`'s first line is a lock-free `self.get(&key)` that returns
+//!       on a hit and never touches any of them — so a cache HIT throws all of

+//!       the owned args only on a miss.
+//!

+//!       one frame (≤256 KB) this copies the whole payload a SECOND time into a

+//!     just split into `path_string` (join temp + unsized `to_string`).
+//!   • folders: same minus the format temp — the materialized `path`
+//!     column arrives owned, is split, dropped, and re-joined into an
+//!     identical `String`.
+//!
+//! The optimized path builds segments + joined string in ONE pass
+//! (`StoragePath::from_folder_and_name` / `from_joined`, the latter
+//! reusing the owned input when canonical) and normalizes the owned name
+//! without the always-copy (`normalize_storage_name_owned`).
+//!
+//! The OLD logic is copied verbatim into `mod before` so one binary
+//! reports BEFORE vs AFTER side by side; an equivalence gate asserts
+//! byte-identical (name, path_string, segments) triples — including
+//! adversarial non-canonical inputs — and error parity for invalid
+//! names (exit 1 on any diff).
+//!
+//! Sections:
+//!   1. File row    wall time (p50 ns/row over BENCH_PASSES passes)
+//!   2. Folder row  wall time (same)
+//!   3. Alloc calls/row (counting allocator wrapping System — the lib
+//!      crate sets no global allocator; mimalloc lives in main.rs only)
+//!   4. Equivalence gate (realistic corpus + adversarial set)
+//!
+//! Run (no Postgres needed):
+//!   cargo run --release --features bench --example bench_row_path
+//! Tunables (env):
+//!   BENCH_ROWS (10000)   BENCH_PASSES (100)

+//! S3 chunk-PUT benchmark — HEAD-before-PUT vs unconditional PUT.
+//!
+//! `DedupService::settle_batch` writes every NEW chunk of every upload via
+//! `put_blob_from_bytes_unsynced`. S3/Azure never overrode it, so the trait
+//! default routed it through `put_blob_from_bytes`, whose "idempotent" HEAD
+//! probe made every chunk write pay 2 request round-trips. Content-addressed
+//! keys make re-PUTs overwrite-safe, so the new override PUTs directly.
+//!
+//! The stub S3 endpoint (in-process axum, per-request latency injection)
+//! counts HEAD/PUT requests:
+//!   BEFORE — put_blob_from_bytes        (HEAD 404 + PUT per chunk)
+//!   AFTER  — put_blob_from_bytes_unsynced (PUT per chunk)
+//!
+//! Section 2 measures the removed Azure `data.to_vec()` copy in isolation.
+//!
+//! Section 3 (round 9) drives the same A/B **through the decorator stacks**
+//! (`RetryBlobBackend`, `CachedBlobBackend`, and the full production
+//! Cache(Encrypted(Retry(S3))) composition). Until round 9 neither Retry nor
+//! Cached overrode `put_blob_from_bytes_unsynced`/`sync_blobs`, so the trait
+//! default silently re-routed every decorated chunk write back through the
+//! probing synced path — undoing this bench's own Section-1 win on every
+//! remote deployment with retry or cache enabled. The BEFORE arm is the
+//! still-present synced route (`put_blob_from_bytes`, byte-identical requests
+//! to what the fallthrough produced); the AFTER arm is the now-forwarded
+//! unsynced route. A write-through equivalence gate asserts the Cached stack
+//! still populates its local cache identically on both routes.
+//!
+//! Gates: AFTER request count == chunks (vs 2x), AFTER wall < BEFORE wall,
+//! per-stack AFTER HEADs == 0, cache population identical on both routes.
+//!
+//! No Postgres. Run:
+//!   cargo run --release --features bench --example bench_s3_put
+//! Tunables: BENCH_CHUNKS (500), BENCH_CHUNK_KB (256), BENCH_CONCURRENCY (8),
+//!           BENCH_RTT_MS (10)

+//! Search-results cache memory benchmark — entry-count bound vs byte bound.
+//!
+//! The search cache keys pages by user × query × offset × limit, and each
+//! page holds up to 500 enriched rows (`MAX_SEARCH_LIMIT`) of owned Strings.
+//! Bounded by ENTRY COUNT (the old scheme: `max_capacity(1000)` + TTL), a
+//! burst of keystrokes/pages/users could pin ~300 MB of invisible RSS for
+//! the 5-minute TTL. Bounded by BYTES (a `weigher` + 32 MiB budget — the
+//! same pattern as the file-content and dedup-manifest caches), retention
+//! can never exceed the budget.
+//!
+//! Two sub-phases over the same synthetic corpus (1,000 pages × 500 rows,
+//! ~150-char paths, realistic field contents):
+//!   * BEFORE — a moka cache configured exactly as the old production wiring
+//!     (entry-count 1000 + 300 s TTL).
+//!   * AFTER  — `build_search_results_cache(...)`, the *identical* function
+//!     production now uses (weigher + 32 MiB + 300 s TTL).
+//!
+//! Reported per phase: entries retained, retained bytes (recomputed with the
+//! production weigher after `run_pending_tasks`), best-effort process memory
+//! (`VmHWM`/`VmRSS` from /proc/self/status), and hot-key `get()` p50 over
+//! 100k reads (proves the weigher — which only runs on insert — does not
+//! slow reads).
+//!
+//! NOTE on RSS: `VmHWM` is a monotonic high-water mark and the allocator may
+//! keep freed pages, so the AFTER phase (which runs second, after a full
+//! drop of the BEFORE cache) cannot show a peak below the BEFORE peak.
+//! Treat the RSS columns as best-effort corroboration; the authoritative
+//! metric is the weigher-recomputed retained bytes.
+//!
+//! Gates (exit code 1 on failure):
+//!   * AFTER retained bytes ≤ 32 MiB budget
+//!   * BEFORE retained bytes ≥ 8× the budget (measured ≈9–10×)
+//!   * AFTER get() p50 within 20% of BEFORE
+//!
+//! No Postgres needed.
+//! Run: `cargo run --release --features bench --example bench_search_cache_mem`

+//! once in `FileDto::from`). The recursive search branch runs this map over
+//! the ENTIRE pre-pagination match set, so a subtree query matching thousands
+//! of files paid ~11 allocs + 3 classifier passes per row. `enrich_folder`
+//! cloned its 4 strings the same way, and the NC REPORT conversion
+//! (`file_dto_from_search`) re-ran all three classifiers a SECOND time per
+//! emitted row.
+//!
+//! Round 9 changes `SearchFileResultDto.{mime_type,icon_class,
+//! icon_special_class,category}` to `Arc<str>`, makes both enrichers consume
+//! their DTO (strings move, interned fields transfer as refcount bumps), and
+//! has the NC conversion reuse the carried values.
+//!
+//! `mod before` holds the pre-round-9 logic verbatim (old struct shape
+//! included); the equivalence gate asserts field-by-field identical output
+//! for every row, and the NC-conversion gate asserts the reused display
+//! fields byte-equal a fresh classifier run.
+//!
+//! Sections:

+//! Static-asset compression benchmark — on-the-fly Brotli per request vs
+//! serving a precompressed sibling.
+//!
+//! The SPA router compressed every compressible static response on the fly
+//! (tower-http `CompressionLayer`, backed by `async-compression`'s Brotli at
+//! `Level::Default`) — the same immutable `/_app/immutable` bundle re-encoded
+//! on EVERY request. The change teaches `ServeDir` to serve build-time
+//! `.br`/`.gz` siblings (`precompressed_br()/precompressed_gzip()` +
+//! `frontend/scripts/precompress.mjs`), so a request costs a file read.
+//!
+//! This isolates exactly that per-request delta on a JS-bundle-like payload:
+//!   BEFORE — Brotli-encode the asset with async-compression Level::Default
+//!            (what the layer does per request)
+//!   AFTER  — read the precompressed sibling from disk (what ServeDir does)
+//!
+//! Run (no Postgres needed):
+//!   cargo run --release --features bench --example bench_static_precompress
+//! Tunables: BENCH_ASSET_KB (700), BENCH_REPS (30)

+//! Shared-album thumbnail authz benchmark — folder-grant cascade query per
+//! thumbnail vs the `cascade_grant_cache`.
+//!
+//! A recipient of a shared folder (a grant on the album folder, NOT drive
+//! membership) fails the drive-role precheck in `PgAclEngine::check_inner` and
+//! falls through to `file_cascade_grant_exists` — an ltree folder-ancestor
+//! grant query — for EVERY file. `get_thumbnail_impl` runs that Read check on
+//! every request, and browsers revalidate immutable thumbnails constantly
+//! (`If-None-Match`), so the same `(recipient, file, Read)` decision is
+//! recomputed again and again: ~one grant query per thumbnail per view.
+//!
+//! Round 8 memoises that decision in `cascade_grant_cache` (30 s TTL, flushed
+//! on any File/Folder grant write). The check still runs on every request —
+//! it is never skipped — but after the first query it resolves in-memory.
+//!
+//! Round 9 additionally decomposes the FILE decision: parent point-read
+//! (memoised) → the FOLDER cascade decision (one ltree query per folder,
+//! shared by every sibling) → direct-file-grant fallback. A shared album's
+//! COLD first view drops from one ltree UNION query per file to one ltree
+//! query per FOLDER plus cheap PK reads. The `ROUND8 cold` arm below runs
+//! the historical UNION verbatim per file for comparison.
+//!
+//! Safety gates (hard asserts, exit 1 on failure):
+//!   1. the folder-grant recipient is allowed; an outsider is denied;
+//!   2. REVOCATION — after a warm cache serves `allowed`, `clear_role` on the
+//!      shared folder makes the very next check DENY (proves the grant-write
+//!      invalidation flushes the cache; without it the stale `true` would
+//!      still serve);
+//!   3. DIRECT-GRANT SIBLING (round 9) — a caller holding ONLY a direct
+//!      grant on one file is allowed that file and denied its siblings,
+//!      proving the folder-level decomposition neither shadows direct file
+//!      grants nor leaks a file decision to siblings.
+//!
+//! Run (needs Postgres up; reads DATABASE_URL from .env):
+//!   cargo run --release --features bench --example bench_thumbnail_cascade_cache
+//! Tunables (env): BENCH_THUMBS (100), BENCH_POOL (8).

+//! Upload spool/assembly I/O benchmark — buffer sizing on the chunk paths.
+//!
+//! Section 1 — assembly read (`stream_from_files`): every completed chunked
+//! upload is read back once, part file by part file, through
+//! `ReaderStream::with_capacity(file, N)`. Each poll is one blocking-pool
+//! dispatch + one read(2) of N bytes; the shipped capacity was 64 KiB while
+//! every other blob read path uses 256 KiB+. Sweeps N over
+//! 64K/256K/512K/1M and reports wall time + read syscalls.
+//!
+//! Section 2 — chunk spool write (`stream_body_to_path`): the PUT handlers
+//! wrote each HTTP frame (~16-64 KiB) straight to a bare tokio File — one
+//! blocking-pool dispatch + write(2) per frame. Compares that against the
+//! adopted `BufWriter::with_capacity(512 KiB)`.
+//!
+//! No Postgres. Run:
+//!   cargo run --release --features bench --example bench_upload_spool
+//! Tunables: BENCH_PARTS (16), BENCH_PART_MB (10), BENCH_FRAME_KB (16),
+//!           BENCH_SPOOL_MB (10), BENCH_REPS (5)

+//!
+//! `file_blob_read_repository.rs` (and friends) SELECT UUID columns as
+//! `id::text` and decode `String`s directly. The alternative is to decode the
+//! wire-native binary `Uuid` (16 bytes vs 36 on the wire) and render the
+//! string app-side with `Uuid::to_string`. This bench decides ROUND6 task
+//! "::text casts A/B" empirically: whichever loses is documented, only a
+//! winner ships.
+//!
+//! Arms fetch the same 500-row page from a seeded `storage.files` subtree,
+//! interleaved A/B to cancel drift; the equivalence gate asserts identical
+//! `(id, folder_id, name)` string triples.
+//!

+/*
+ * Emit `static-dist/askama-common.css` from the SvelteKit design-token
+ * source of truth (`src/lib/styles/base/variables.css`) plus the auth-page
+ * component styles (`src/lib/styles/askama-common.css`).
+ *
+ * WHY A POST-BUILD SCRIPT:
+ *   Vite's `writeBundle` hooks fire mid-build, before
+ *   `@sveltejs/adapter-static` copies the finalised site to
+ *   `../static-dist/`. Anything written to that directory during
+ *   Vite gets wiped when adapter-static runs. A `postbuild` script
+ *   runs after everything the SvelteKit build owns, so its output
+ *   survives — one predictable moment, no ordering trap.
+ *
+ * WHAT IT PRODUCES:
+ *   A single stable-named CSS file at `static-dist/askama-common.css`
+ *   containing:
+ *     1. Every design token declared in `base/variables.css` (:root,
+ *        `light-dark(...)`, dark-mode blocks, etc.)
+ *     2. The auth-page component rules from `askama-common.css`
+ *   Concatenated, prefixed with a "do not edit" header, written UTF-8.
+ *
+ * SINGLE SOURCE OF TRUTH:
+ *   If a token changes in `variables.css`, one rebuild propagates it to
+ *   both the SPA (via Svelte's normal build pipeline) AND the askama
+ *   templates (via this file). Two consumers, one source. No manual
+ *   sync step.
+ *
+ * SERVER SIDE:
+ *   Server-rendered askama templates reference:
+ *     <link rel="stylesheet" href="/askama-common.css">
+ *   The Rust web layer serves `static-dist/askama-common.css` at that
+ *   URL through the same ServeDir the SPA uses. No route wiring needed.

+ * ran the workload in **Node's vitest environment**, using
+ * `crypto.createHash('sha256')` and `node:worker_threads`. That's not
+ * representative of the browser architecture the code actually ships

+ *
+ *   - The real code hashes with WASM BLAKE3 (~100 MB/s in a browser)
+ *     across a pool of Web Workers.
+ *   - Node's `crypto` sha256 is native C++ (~500–1000 MB/s) and its
+ *     `worker_threads` postMessage has different overhead characteristics.
+ *
+ * At native-crypto speed the 4 MiB hash completes in ~8 ms per file,
+ * so the message-passing round-trip cost per file becomes a comparable
+ * fraction of the total — even a *perfect* 3-lane parallelization has
+ * to overcome ~1/3 of its own runtime in messaging cost. Any CI
+ * variance pushes it over the sequential wall-clock, so the test
+ * false-fails while the actual browser code is fine.
+ *
+ * The optimization itself is defensible on two grounds:
+ *   1. Theoretical parallelism win: at WASM BLAKE3 speed the messaging
+ *      overhead is a rounding error and 3 lanes beat sequential ~2.5×.
+ *   2. Main-thread responsiveness: even if the wall-clock ended up flat,
+ *      offloading the ~1 s of CPU-bound hashing to workers keeps the
+ *      UI responsive during upload prep.
+ *
+ * Neither of those is validated by a Node vitest. The real gate belongs

+	// ── System-drop handling (OS files onto the wrapper) ───────────────────────
+	// Two modes:
+	//
+	//   * `enableSystemDrop = true`: the page has an upload code path
+	//     ready (the `/files` browser). We `preventDefault` the browser's
+	//     default (which would open the dragged file as a top-level
+	//     navigation), highlight the drop zone, and hand the DragEvent
+	//     off to the page via `onsystemdrop`. The page walks the entries
+	//     (webkitGetAsEntry / DataTransferItemList) and drives the upload.
+	//
+	//   * `enableSystemDrop = false` (default): the page has no upload
+	//     path. Still `preventDefault` so the browser doesn't navigate
+	//     away, but instead of forwarding, fire a `ui.notify()` that
+	//     points the user at `/files` — this restores the legacy vanilla
+	//     frontend's "wrong drop zone" behaviour so users don't wonder
+	//     why their drag was silently ignored.
+	//
+	// Row-scoped drops (dragging an in-app row onto a folder row / the
+	// breadcrumb) are handled by the existing `onitemdrop` hooks and use
+	// a private `application/x-oxi-item` MIME so the `Files` type check
+	// below never matches them.
+	// Drag-enter/leave chatter is unavoidable when the drag pointer moves
+	// between the wrapper and its descendants — the browser fires
+	// `dragleave` on the parent BEFORE firing `dragenter` on the child,
+	// so a naive `systemDropOver = false` in the leave handler produces
+	// a false→true flash on every row hover during the drag. Counter
+	// approach: increment on every dragenter, decrement on every
+	// dragleave; the overlay is visible when the count is positive. The
+	// count zeroes only when the drag has truly left the wrapper (or
+	// hit `drop`/`dragend`), so the overlay stays stable throughout.

+ *   Dark-mode detection uses `light-dark()` + the `color-scheme` on

+ *   (login / magic-link error) — no per-user override needed. Browsers

+/**
+ * Incremental swimlane bucketing for `ResourceList`, extracted from the
+ * component so the O(N²) accumulation of its `sections` `$derived` can be
+ * replaced with an append-aware builder (and unit/benchmark-tested off the
+ * Svelte reactive graph).
+ *
+ * `ResourceList` pages its list in via infinite scroll (`raw = [...raw,
+ * ...page]`), and `sections` was `$derived` over the WHOLE accumulated list —
+ * so paging to item N re-buckets everything loaded so far, Σ ≈ O(N²/page)
+ * main-thread work during the scroll (the same class ROUND6 fixed for the
+ * files listing and ROUND14 §F2 fixed for favorites, and PhotoTimeline fixed
+ * for the photos grid).
+ *
+ * Grouped listings sort by the active group's `orderBy`, so a fresh page only
+ * ever extends existing buckets or appends new ones — it never reorders an
+ * already-emitted bucket. {@link ResourceSectionsBuilder} exploits that: an
+ * append re-buckets only the fresh page and hands back the SAME array
+ * reference for every untouched bucket (so `VirtualList`, which diffs its
+ * `items` prop by reference, skips re-rendering it) while emitting a fresh
+ * array for each bucket the page actually grew.
+ *
+ * Correctness does not depend on bucket contiguity: even a group-by whose
+ * `bucketOf` is not monotonic in server order (e.g. trash grouped by drive but
+ * ordered by name) stays byte-for-byte equal to the full rebuild — it just
+ * touches more buckets per page. The pure {@link buildResourceSections} is the
+ * verbatim reference (what the old `sections` derive produced); the benchmark
+ * gate asserts the incremental builder stays deep-equal to it at every page.

+/**
+ * Incremental swimlane builder for the "My shares" page (`shared/+page.svelte`).
+ *
+ * The ROUND15-deferred follow-up to the F1 flagship (`resourceSections.ts`):
+ * that fix replaced `ResourceList`'s `sections` derive; this one replaces the
+ * `lanes` `$derived.by` on the shares page, which had the same O(N²/page)
+ * shape. The page pages its outgoing grants in via infinite scroll
+ * (`raw = [...raw, ...page.items]`), and `lanes` re-bucketed the WHOLE
+ * accumulated (filtered) list on every page — and on every grant edit —
+ * allocating a brand-new lane object and a brand-new `rows` array for every
+ * lane each time. Σ ≈ O(N²/page) `emit` calls across an infinite-scroll drain.
+ *
+ * The lanes shape differs from `resourceSections` in two ways, so it gets its
+ * own builder rather than reusing `ResourceSectionsBuilder` (only the O(1)
+ * append test is genuinely shared — see {@link isAppendExtension}):
+ *
+ *  - **Fan-out.** One input item contributes 0..N rows across 0..M lanes (in
+ *    the "shared with" group-by a resource's grants scatter across one lane per
+ *    distinct subject), whereas a resource section maps one item to exactly one
+ *    bucket with the item itself as the row.
+ *  - **Header captured at first appearance.** A lane's header (a tagged union
+ *    identifying the resource / subject / link kind) is fixed by the lane's
+ *    first-seen member and never recomputed — unlike a section's `label`, which
+ *    is recomputed every sync because it resolves async. (The shares page mirrors
+ *    that: it renders the header's *label* live via `resolveLabel(...)` at render
+ *    time from the stable header, so only the header identity is cached here.)
+ *
+ * Correctness does not depend on lane contiguity in server order. The
+ * "shared with" group-by is non-monotonic — a fresh page sprays rows across
+ * already-emitted subject lanes — exactly like F1's "trash by drive" case, and
+ * stays byte-for-byte equal to a full rebuild (it just refreshes more lanes per
+ * page). The pure {@link buildLanes} is the verbatim reference (what the old
+ * `lanes` derive produced); the benchmark gate holds the incremental builder
+ * deep-equal to it at every page.

+	// page 1 against the snapshot — every new id joins `newlyAdded`.
+	//
+	// Known limitation: server-sort places the new item on an unloaded
+	// page (e.g. sort=size on a 5 000-item folder and the new file is
+	// mid-size). It won't appear in the swimlane until the user scrolls

+/**
+ * Benchmark gate for the files view's batch-operation rework
+ * (`batchDelete` / `moveInto` / `selectionTargets` / `batchDownload` in
+ * `[...path]/+page.svelte`).
+ *
+ * Audit finding: multi-item delete/move awaited one request per item in a
+ * serial loop — at ~30 ms RTT a 100-item delete is ~3 s of waterfall — and
+ * every per-id classification ran `listing.folders.find(...)` /
+ * `listing.files.some(...)`, an O(N·M) scan over the listing per selected id.
+ * The fix builds an id index once (O(M)) and fans the requests out through
+ * the view's existing `mapLimit` with 6 in flight.
+ *
+ * The functions are component-internal, so — like the Rust bench modules that
+ * replicate handler internals — this bench replicates BEFORE verbatim and
+ * AFTER (index + `mapLimit`, the exact shapes now in the component) against a
+ * stubbed per-item endpoint with simulated latency.
+ *
+ * Gates: (1) both arms attempt the identical (id, kind) operation set —
+ * folder-first classification preserved; (2) a 100-item batch at 5 ms
+ * simulated RTT completes ≥3x faster; (3) the classification scan count
+ * drops from O(N·M) to one pass.

+ *     BEFORE shape ends showing the FIRST (stale) query's results; the
+ *     guarded AFTER shape always ends with the LAST query's results.
+ *  2. Perf — the AFTER shape aborts every superseded request: for N

+// Browsers that installed the old SW keep it registered across upgrades

+// module exists) — this file exists solely to shepherd upgraders off the
+// legacy SW. Browsers on a clean install fetch it, install it, immediately
+// unregister it, and the URL stays a 200 for the next visitor with the
+// same stale-SW problem.
+//
+// The install/activate handlers race the browser's normal SW lifecycle;
+// `skipWaiting` + `clients.claim` fast-forward through the "waiting" and

+-- ════════════════════════════════════════════════════════════════════════════
+-- D0/M5 (`20260802100004_copy_folder_tree_drive_id.sql`) introduced drive_id
+-- into this function but pulled it from the SOURCE folder for every level —
+-- a deliberate "intra-drive only" limitation called out in that migration's
+-- header. After D6 landed cross-drive moves end-to-end (cascade trigger +
+-- WITH dest CTE on file_move/folder_move) copies were the lone holdout: a
+-- batch-copy of a folder tree into another drive left every new row with
+-- the SOURCE's drive_id while parent_id pointed into the DESTINATION drive.
+-- Net effect: the per-drive quota sweep (`SUM(size) WHERE drive_id = d.id`)
+-- charged the SOURCE drive for size physically living under the dest tree.
+--
+-- The fix mirrors `copy_file` SQL in
+-- `infrastructure/repositories/pg/file_blob_write_repository.rs::copy_file`
+-- (the single-file copy path already gets drive_id from the destination via
+-- a `dest_folder` CTE) — here we resolve the destination drive ONCE at the
+-- top of the function and bind it for every level of folders + every file.
+--
+-- Provenance contract: `created_by` / `updated_by` on the copied rows STAY
+-- as the source row's values. A copy is a duplicate, not a new authoring
+-- event; preserving the original author across copies is the correct
+-- semantic. Subsequent edits to the copy bump `updated_by` through the
+-- normal write path. This makes the previously-deferred caller_id thread
+-- (memory: project_copy_folder_tree_caller_id.md) unnecessary — drive_id
+-- is the only field that needs the destination's perspective.
+--
+-- Preserved semantics from the prior body:
+--   - level-by-level folder INSERTs so trg_folders_path can resolve
+--     parent's path/lpath from rows inserted in the previous level.
+--   - One batched file INSERT (zero-copy via blob hash) at the end.

+-- Fix: descendant path/lpath cascade silently stopped firing after D6
+-- ════════════════════════════════════════════════════════════════════════════
+-- The D6 migration `20260807000000_cascade_drive_id_on_folder_move.sql` was
+-- written to add `drive_id` to the cascade trigger's column list. Its stated
+-- intent (per its own comment) was "add `drive_id` to the column list", but
+-- the re-registration replaced `name, parent_id, path, lpath` with
+-- `path, lpath, drive_id` — dropping `name` and `parent_id` in the process:
+--
+--     -- D6 as shipped (BUG):
+--     CREATE OR REPLACE TRIGGER trg_folders_cascade_path
+--         AFTER UPDATE OF path, lpath, drive_id ON storage.folders
+--         FOR EACH ROW EXECUTE FUNCTION storage.cascade_folder_path();
+--
+-- PostgreSQL's `UPDATE OF <cols>` predicate matches against the statement's
+-- explicit SET clause — NOT against what a BEFORE trigger derives. The
+-- rename SQL the app issues is `UPDATE storage.folders SET name = $1, ...`
+-- and the move SQL is `UPDATE storage.folders SET parent_id = $1, ...`.
+-- Neither touches path/lpath/drive_id in its SET list. Net effect of D6:
+--
+--   * Folder rename: BEFORE trigger (trg_folders_path) correctly rewrites
+--     the renamed row's `path` and `lpath` columns directly. AFTER cascade
+--     trigger never fires → every DESCENDANT folder retains its old `path`
+--     and `lpath` indefinitely. Hidden until a path-keyed lookup misses.
+--   * Folder move (intra-drive): same regression, same hidden state.
+--   * Folder move (cross-drive): drive_id IS in the SET clause for some of
+--     the cross-drive code paths, so D6's drive_id branch fires there. But
+--     the path/lpath branch in the same function never fires on rename/move
+--     because the trigger gate excludes the SET columns the app uses.
+--
+-- Discovery: litmus `copymove → move_coll` (test #10) — `DELETE
+-- /webdav/litmus/mvdest/subcoll/` returns 404 because `subcoll`'s path
+-- column is still `Personal/litmus/mvsrc/subcoll`. The 10 leaf files
+-- foo.0..foo.9 directly under mvdest delete fine because their lookup
+-- joins through their parent folder's row (mvdest itself), and the BEFORE
+-- trigger DID update mvdest's own path correctly on rename. Only DESCENDANT
+-- folder rows are affected.
+--
+-- Fix: re-register the trigger with the column list that covers every
+-- statement the app actually issues against storage.folders:
+--   - `name` — folder rename
+--   - `parent_id` — folder move (intra-drive)
+--   - `path`, `lpath` — direct rewrites (migrations, future tooling)
+--   - `drive_id` — folder move (cross-drive); preserved from D6
+--
+-- The cascade function body itself is unchanged. The pg_trigger_depth() > 1
+-- guard inside it still stops the descendant-rewrite UPDATE from
+-- recursively re-firing the trigger on its own writes.
+
+-- DROP-then-CREATE for PG 13 compatibility (no CREATE OR REPLACE TRIGGER
+-- pre-14). Idempotent thanks to IF EXISTS / IF NOT EXISTS semantics.
+DROP TRIGGER IF EXISTS trg_folders_cascade_path ON storage.folders;
+CREATE TRIGGER trg_folders_cascade_path
+    AFTER UPDATE OF name, parent_id, path, lpath, drive_id ON storage.folders
+    FOR EACH ROW EXECUTE FUNCTION storage.cascade_folder_path();
+
+-- ── Repair: rebuild stale descendant path/lpath on existing databases ────
+-- Any folder rename or intra-drive move that happened between D6 deploying
+-- and this fix landing left descendants stranded at their pre-rename path
+-- and lpath. The same canonical-rebuild CTE used in
+-- `20260730000001_statement_tree_etag.sql` heals the pile in a single
+-- statement: walk the tree from each root, derive (path, lpath) from the
+-- parent chain, write back only the stale rows.
+--
+-- Two safety properties of this repair:
+--   * The repair UPDATE sets `path` and `lpath` directly. The newly-
+--     correct trigger column list above DOES include those columns, but
+--     `cascade_folder_path()` only descends to children when OLD differs
+--     from NEW *for that row* — descendants are walked level by level by
+--     the recursive CTE, so by the time the trigger fires on a child, the
+--     child's parent already has its correct path and the child's row is
+--     also being rewritten to its correct path. No double-write, no fan-
+--     out: the CTE finishes before any trigger could redo the work.
+--   * The statement-level tree-ETag bump triggers run their column filter
+--     against `(name, parent_id, is_trashed, updated_at)` — none of which
+--     change in this UPDATE — so existing sync clients see no spurious
+--     ETag churn.

+-- WebDAV dead properties: rekey from (resource_path, user_id) to resource id
+-- ════════════════════════════════════════════════════════════════════════════
+-- The original schema (20260825000000) keyed dead properties on
+-- `(resource_path, user_id, namespace, local_name)`. That model was wrong on
+-- two counts:
+--
+--   1. Dead properties are RESOURCE state per RFC 4918 §4.2 — not user
+--      state. Two users on a shared drive PROPFIND'ing the same resource
+--      must see the same dead-properties. The user_id key siloed them.
+--   2. Every non-WebDAV delete path (REST `DELETE /api/files/{id}`, bulk
+--      delete, trash empty, folder cascade) operates on a resource id —
+--      not a path. None of those code paths could cheaply call
+--      `remove_resource(path, user_id)`, so they leaked dead-property
+--      tombstones. WebDAV DELETE itself had a workaround explicit-cleanup
+--      call, but the REST surface (which the SvelteKit web UI uses) is the
+--      dominant delete path in practice.
+--
+-- This migration switches the key to a polymorphic resource reference:
+-- exactly one of `folder_id` / `file_id` is set, each with `ON DELETE
+-- CASCADE` to its owning table. After this lands every existing
+-- delete code path — REST, WebDAV, NextCloud DAV, trash, folder
+-- cascade — automatically reaps dead-property rows when the underlying
+-- file or folder is removed, with no service-layer changes.
+--
+-- MOVE / RENAME also become no-ops at the dead-properties layer: a
+-- folder's id is stable across renames, so its dead properties move
+-- with it for free. The `rename_resource()` method on the store is
+-- removed in the matching Rust change.
+--
+-- ── Migration shape ─────────────────────────────────────────────────────────
+-- 1. ADD COLUMN folder_id / file_id (NULL-able for now).
+-- 2. Backfill folder_id from any row whose resource_path matches a
+--    folder row's `path` + `user_id`.
+-- 3. Backfill file_id for the rest by joining through the parent folder
+--    and matching `parent.path || '/' || fi.name`.
+-- 4. Reap rows that didn't resolve — they're tombstones from before
+--    the FK-cascade fix, and there's no resource left to attach them to.
+-- 5. Add the CHECK constraint that exactly one column is set.
+-- 6. Add two partial unique indexes (one per kind).
+-- 7. DROP the old columns; PG drops the inline UNIQUE constraint and
+--    the explicit path/user index along with them.
+--
+-- The migration runs in a single sqlx transaction. If any step fails
+-- the schema rolls back to (20260825000000) intact.

+-- ════════════════════════════════════════════════════════════════════════════
+-- COPY: duplicate dead properties along with files and folders
+-- ════════════════════════════════════════════════════════════════════════════
+-- RFC 4918 §8.8 — "If a property cannot be copied live, then its value
+-- MUST be duplicated, exactly as it would be for a PROPPATCH SET
+-- operation, in the copy." Dead properties are by definition not live
+-- (the server stores them verbatim with no interpretation), so every
+-- COPY MUST duplicate the source's dead properties onto the new
+-- resource.
+--
+-- The pre-rekey path-based store handled this by accident in some
+-- cases and missed it in others; the id-keyed store (migration
+-- 20260830000001) makes the requirement explicit — dead properties
+-- key on `folder_id` / `file_id`, so a copy that doesn't insert new
+-- rows for the destination's ids loses the properties entirely.
+--
+-- This migration replaces `storage.copy_folder_tree` with a version
+-- that:
+--
+--   1. Pre-allocates destination file ids in a new temp table
+--      `_copy_file_map(old_id, new_id)` — analogous to the
+--      pre-existing `_copy_map` that already does this for folders.
+--      Previously, file ids were generated by the `gen_random_uuid()`
+--      DEFAULT during the batch INSERT, leaving no way to relate src
+--      and dst files afterward.
+--   2. Switches the batch file INSERT to use the explicit
+--      pre-allocated id, so src→dst is bidirectionally known by
+--      `_copy_file_map`.
+--   3. Adds two `INSERT INTO storage.webdav_dead_properties` SELECTs
+--      at the end that duplicate dead-property rows for every copied
+--      folder (via `_copy_map`) and every copied file (via
+--      `_copy_file_map`). Each duplicated row carries the same
+--      `(namespace, local_name, value)` triple as the source — the
+--      definition of "duplicate" in RFC 4918 §8.8.
+--
+-- Idempotent via CREATE OR REPLACE FUNCTION. No callers change (the
+-- function signature and return shape are unchanged).
+--
+-- COPY semantics out of scope for this migration:
+--   * Cross-user permission handling on the copied resources is the
+--     caller's responsibility (the `_with_perms` service variant
+--     already enforces this on the source side). Dead properties
+--     hitch a ride on the resource's ACL; nothing additional needed.
+--   * Trash: trashed source rows are excluded by the existing
+--     `NOT is_trashed` filter; dead-props on trashed rows live on
+--     until the resource itself is hard-deleted, at which point
+--     CASCADE handles them. Same model holds in the new COPY path.

+-- companion Rust rewrite).
+--
+-- New default personal drives get these flags at creation time via
+-- `DriveRepository::create_personal_drive_atomic` (the INSERT literal on
+-- that path was updated alongside this migration). This migration handles
+-- the existing rows, seeded by the D0 backfill.
+--
+-- Non-default drives (secondary personals, shared drives) are NOT touched —
+-- they stay opted-out until the owner flips the flag via the admin
+-- "Manage policies" modal.
+--
+-- Idempotent: `policies || {…}` is a no-op if the keys are already set to
+-- the same values, and JSONB `||` is right-precedence so the migration
+-- never overwrites an owner's explicit opt-out that was already recorded.
+-- (If someone had `include_in_photo_index=false` set on their default
+-- personal via a manual PATCH, this UPDATE would still overwrite to true;
+-- that's acceptable — the D5 policy UI didn't exist for these flags
+-- before this PR, so no such manual opt-out can be in the wild yet.)

+-- PR-B — storage.caller_group_ids: recursive group-membership expansion in SQL
+-- ════════════════════════════════════════════════════════════════════════════
+-- Every listing surface that scopes by "drives the caller can Read" (Photos,
+-- Places, GET /api/drives, Trash, Search, root-folder listing) needs the
+-- caller's *effective subject set* = caller_id ∪ every group they belong to
+-- transitively.
+--
+-- Pre-Option-A the Rust-side `PgAclEngine::expand_subject_for_listing` did
+-- the walk once (via `WITH RECURSIVE` in `subject_group_pg_repository.rs::
+-- groups_for_user`) and cached the result in a Moka table with 30-second
+-- TTL; every listing handler then passed the two parallel arrays
+-- `subject_types` + `subject_ids` into the SQL. That leaked the expansion
+-- ceremony into every caller (7+ sites).
+--
+-- Option A pushes the walk into a `STABLE` SQL function so each listing
+-- query embeds the expansion inline:
+--
+--   WHERE (g.subject_type = 'user'  AND g.subject_id = $caller)
+--      OR (g.subject_type = 'group' AND g.subject_id IN
+--              (SELECT storage.caller_group_ids($caller)))
+--
+-- Callers pass a bare `caller_id: Uuid` — no more expand-then-bind
+-- ceremony. Postgres re-runs the walk per listing (~1-3 ms against the
+-- indexed `auth.subject_group_members` table); we lose the Moka cache
+-- benefit but gain a single audit trail for "how does group access
+-- cascade" (this function) and drop ~15 lines of Rust glue per listing.
+--
+-- Cycle safety: `subject_group_pg_repository.rs::add_member` enforces
+-- an INSERT-time cycle check via `WITH RECURSIVE descendants`, so the
+-- membership DAG is guaranteed acyclic. Depth is capped at
+-- MAX_GROUP_DEPTH by the same INSERT path. The recursion below always
+-- terminates.
+--
+-- `STABLE`: the function reads DB state but never modifies it, and the
+-- result is deterministic within a transaction. Postgres can memoise
+-- calls within a single query plan (e.g. multiple references in the
+-- same SELECT) and inline the CTE into the surrounding query where
+-- beneficial. Marking it `VOLATILE` would forbid both optimisations.
+--
+-- `LEAKPROOF` is deliberately NOT set: the function reads a private
+-- auth table, so it must not be pushed below a security barrier.
+--
+-- `SECURITY INVOKER` (the default) — runs with the calling role's
+-- permissions, so RLS on `auth.subject_group_members` (if ever added)

+-- D7 step 5 — retire `user_id` as a write/uniqueness axis on
+-- `storage.files` and `storage.folders`.
+--
+-- Every read that used to filter by `files.user_id = $caller` or
+-- `folders.user_id = $caller` has already been migrated to a
+-- drive-membership predicate (see D7-pass §6/§10 changes:
+-- `file_blob_read_repository`, `folder_db_repository`,
+-- `path_resolver_service`, `dedup_service`, plus `authz.require(Read, …)`
+-- at every WebDAV consumer site). This migration removes the last
+-- reason to keep binding `user_id` on writes:
+--
+--   1. Files uniqueness indexes swap from `(folder_id, name, user_id)` /
+--      `(name, user_id)` → `(drive_id, folder_id, name)` /
+--      `(drive_id, name)`. Post-D0 `files.drive_id` is `NOT NULL`, so
+--      the drive-scoped form is strictly stronger — a file is unique
+--      by its position within its drive, not by "who used to own it".
+--      The folder side already got this treatment in D0
+--      (`20260802100002_drives_not_null.sql`).
+--
+--   2. Dead user_id-leading indexes get dropped:
+--        - `idx_files_user_id`, `idx_folders_user_id` — nothing scans by
+--          `WHERE user_id = $1` any more.
+--        - `idx_folders_trashed` — was `(user_id, is_trashed)`; the
+--          trash listing moved to `(drive_id, is_trashed)` via the
+--          same D7 rewrite.
+--        - `idx_files_user_size_active` — was the per-user storage
+--          usage summary; the reconciliation sweep now GROUPs by
+--          `drive_id` (`storage_usage_service::update_all_drives_storage_usage`).
+--
+--   3. `ALTER COLUMN user_id DROP NOT NULL` on both tables. The
+--      column stays for compat with the follow-up column-drop
+--      migration (D7 step 6) but new INSERTs will leave it NULL.
+--      Existing rows keep their backfilled values until the drop.
+--
+-- Steps 4-6 (Rust INSERT binds dropped + PL/pgSQL copy_folder_tree

+-- D0-step-8 companion — cascade-delete guard for the orphan-root check.
+--
+-- Fixes a latent bug in `storage.check_no_orphan_root_folder` that
+-- surfaced during user-delete tests. Repro (verified against a fresh
+-- test DB with no other data):
+--
+--   INSERT INTO auth.users … one user
+--   Run the atomic personal-drive create (drive + root folder +
+--     drives.root_folder_id wire-up + owner role_grant)
+--   DELETE FROM auth.users WHERE id = <that user>
+--   → ERROR: Orphan root folder rejected …
+--
+-- Root cause — the FK columns `storage.folders.created_by` and
+-- `storage.folders.updated_by` are declared
+-- `REFERENCES auth.users(id) ON DELETE SET NULL` (D0/M1 migration
+-- `20260802100000_drives_schema_additive.sql`, lines 117-129). So when
+-- `DELETE FROM auth.users` runs, PostgreSQL cascades a SET NULL
+-- update onto every folder row referencing that user — including that
+-- user's own personal-drive root folder. That UPDATE fires the
+-- DEFERRED `trg_no_orphan_root_folder` constraint trigger, which queues
+-- a check on the row's `NEW` state.
+--
+-- Cascade order (all inside the same transaction) is: SET NULL on the
+-- folder → cascade DELETE storage.drives (default_for_user FK) →
+-- cascade DELETE storage.folders (drive_id FK). By COMMIT, the drive
+-- and the folder are both gone. When the deferred trigger fires, its
+-- query `EXISTS (drive d WHERE d.id = NEW.drive_id AND d.root_folder_id
+-- = NEW.id)` finds no drive, so it raises. The check is correct in
+-- isolation — but the row it's checking no longer exists, so the
+-- invariant it's protecting no longer applies.
+--
+-- Fix: add an existence guard before the drive lookup. If the row has
+-- been deleted in the same transaction, skip the check — a deleted row
+-- can't be an orphan by definition.
+--
+-- This preserves the original invariant on all live rows:
+--   * The atomic four-write create transaction still gets checked at
+--     COMMIT and still requires the drive→folder wire-up (the folder
+--     row exists at COMMIT because we didn't delete it).
+--   * Direct SQL that tries to insert an orphan root folder is still
+--     rejected (the INSERT queues a check, the row exists at COMMIT,
+--     the drive lookup fails, exception raised).
+--   * The only new behaviour is "if this row was deleted before COMMIT,
+--     silently skip" — which is what the caller wanted anyway.
+--
+-- No table changes, no data changes, no reverse migration needed —
+-- `CREATE OR REPLACE FUNCTION` is idempotent, and every future call
+-- of the trigger picks up the new body immediately.

+-- caldav.calendar_events — add RECURRENCE-ID column for exception instances
+-- ════════════════════════════════════════════════════════════════════════════
+-- Motivation: AtalayaLabs/OxiCloud#528 — CalDAV clients (Thunderbird, Apple
+-- Calendar, Gnome Calendar, DAVx⁵) modify a single occurrence of a recurring
+-- event by PUTting a separate VEVENT that shares the master's UID and adds
+-- a RECURRENCE-ID identifying which occurrence is overridden (RFC 5545
+-- §3.8.4.4).
+--
+-- Pre-#528 behaviour: modifications either hit a UID collision (silent
+-- 500 or corrupt state) or overwrote the master. Post-#528 the exception
+-- override lives as its own row keyed by
+-- (calendar_id, ical_uid, recurrence_id), with the master identified by
+-- `recurrence_id IS NULL`.
+--
+-- Related but distinct from parser Phase 1 (rewrite of extract_ical_property
+-- on top of the `ical` crate) — that landed in the same branch to enable
+-- parsing RECURRENCE-ID at all. This migration is the storage half.
+--
+-- No backfill needed — pre-migration events all become masters (NULL). No
+-- existing exception rows existed because the parser couldn't read them.

+-- Heal + pin the "personal drives always have NULL quota_bytes"

+--
+-- Bug (#595): `folder_service.rs::PersonalDriveLifecycleHook` was
+-- calling `create_personal_drive_atomic(user_id, Some(user.storage_quota_bytes()))`,
+-- baking the user's envelope quota into `storage.drives.quota_bytes`
+-- for every personal drive. Two conventions then collided at upload
+-- time:
+--
+--   * User-envelope check (`check_storage_quota`) treats `0` as
+--     unlimited (`quota <= 0 → Ok`).
+--   * Drive-quota check (`check_drive_quota`) treats `NULL` as
+--     unlimited but `Some(0)` as a literal zero-byte cap.
+--
+-- Setting user quota to 0 in the Admin UI ("unlimited" per the UI
+-- convention) therefore stamped `drives.quota_bytes = 0` on the
+-- personal drive at creation, and every subsequent upload was
+-- rejected with 507 Insufficient Storage.
+--
+-- Rust-side fix: `folder_service.rs` now passes `None`. This
+-- migration:
+--
+--   1. NULLs every existing personal drive's `quota_bytes` so already-
+--      created users can upload immediately after deploy (Fix 2).
+--   2. Adds a CHECK constraint so any future code path that tries to
+--      write a non-NULL quota on a personal drive fails at the DB
+--      layer instead of silently corrupting state (Fix 3).
+--
+-- Shared drives are untouched — their quota model is orthogonal and
+-- the "NULL = unlimited, positive = numeric cap, 0 = literal zero"
+-- semantics are the design (an admin can legitimately lock a shared

+
+Non-obvious rules that trip up new code. Terse on purpose.
+
+## Auth policy
+
+- **OIDC is the master identity provider.** Whenever `AuthApplicationService::oidc_enabled()` returns true, magic-link login MUST be off — `is_magic_link_login_allowed()` returns false regardless of `OXICLOUD_AUTH_METHODS`. Rationale: OIDC may enforce 2FA / step-up; a mailbox-possession bypass would silently sidestep it.
+- **Password / magic-link handlers gate via `is_password_login_allowed()` / `is_magic_link_login_allowed()`**, never raw config or `password_login_disabled()` alone. The composed helpers merge the legacy OIDC-only flag, `OXICLOUD_AUTH_METHODS`, SMTP wiring, and the OIDC-master rule in one place.
+- **Magic-link redemption** distinguishes login tokens (`resource_kind = None`) from invitation tokens (File / Folder). The login gate only applies to the None case; invitations follow their own admin-mediated trust chain.
+- **`OXICLOUD_REQUIRE_VERIFIED_EMAIL`** gates login on `email_verified_at IS NOT NULL`. Admin-created (`admin_create_user`) and setup-admin (`setup_create_admin`) users are stamped verified at creation — admin fiat counts. OIDC-JIT already stamps verified. Admins are EXEMPT from the gate at login regardless of `email_verified_at` — pre-existing admin accounts from before this flag shipped must never be locked out of their own instance. Regular users hit the gate; the frontend detects the `EmailNotVerified` error_type and offers a resend-magic-link CTA.
+- **Startup gate in `main.rs`**: magic-link-only allowlist + no SMTP = panic. Never soften to warn.
+
+## New auth surfaces
+
+- Any new endpoint that mints or consumes credentials/tokens must consult one of the `is_*_login_allowed()` helpers, not the raw allowlist.
+- Any new "policy-disabled" refusal must emit an `audit`-target line before returning — matches `auth.login_rejected`, `magic_link.redemption_rejected` conventions.

 //! Contact Storage Adapter
 //!
-//! This adapter implements the `AddressBookUseCase` and `ContactUseCase` application ports
-//! using the domain repositories. It bridges the gap between the application layer
-//! and the infrastructure layer for CardDAV functionality.
+//! Implements [`ContactStoragePort`] using the three PostgreSQL
+//! repositories (`AddressBookPgRepository`, `ContactPgRepository`,
+//! `ContactGroupPgRepository`).
+//!
+//! **Pure storage port.** No access-control logic, no sharing state,
+//! no owner-vs-shared listing carve-outs — every method is plain
+//! delegation to a repository. Access decisions live in
+//! `AuthorizationEngine`; sharing state lives in
+//! `storage.role_grants`. The service layer (`ContactService`) gates
+//! each call before reaching through this port.
+//!
+//! Symmetric with `CalendarStorageAdapter`. Post-Round-3 the
+//! pre-existing 1000-line adapter that mixed the use-case impls +
+//! bespoke `check_address_book_access` was deleted; this file
+//! recreates a much smaller storage-only version.

+//! Recording side of [`ResourceAccessHook`] — turns a successful file access
+//! into a row in `auth.user_recent_files` via [`RecentService`].
+//!
+//! Wiring lives in `common/di.rs`: this hook is registered once, every
+//! `_with_perms` file method on `FileRetrievalService` / `FileManagementService`
+//! fans through it, and any future read-path or write-path service can opt in
+//! by holding an `Option<Arc<dyn ResourceAccessHook>>` and calling
+//! `on_file_accessed` after authZ.
+//!
+//! Two non-obvious behaviours, with rationale:
+//!
+//! * **Per-(caller, file) 60-second throttle.** Range-stream downloads send
+//!   one GET per chunk (NC desktop, video seek, resumable transfers); without
+//!   throttling each chunk would trigger an upsert against the same row.
+//!   Moka's `time_to_live` gives us bounded memory and lock-free reads. The
+//!   underlying `INSERT … ON CONFLICT DO UPDATE accessed_at = now()` is
+//!   idempotent, so the rare TOCTOU window between `contains_key` and `insert`
+//!   is harmless — at worst we record twice for the same instant.
+//!
+//! * **Fire-and-forget via `tokio::spawn`.** The `ResourceAccessHook` method
+//!   is synchronous by contract (every `with_perms` caller would otherwise
+//!   have to `await` the side-effect). The spawn lets the user-facing
+//!   response return immediately; a DB hiccup in Recent recording never
+//!   bubbles up to the GET / PUT that triggered it. Failures log at warn.

+//! PostgreSQL-backed dead property store for WebDAV PROPPATCH / PROPFIND compliance.
+//!
+//! RFC 4918 §4.2 defines "dead properties" as those stored verbatim by the
+//! server without interpreting their value. Properties are persisted to
+//! `storage.webdav_dead_properties` and survive server restarts.
+//!
+//! Keying contract (after migration 20260830000001): the row is keyed by
+//! the underlying resource id — exactly one of `folder_id` / `file_id` is
+//! set — not by the resource's current path. Three consequences:
+//!
+//!   * Every delete code path (REST, WebDAV, NextCloud DAV, trash empty,
+//!     folder cascade) reaps dead-property rows for free via FK
+//!     `ON DELETE CASCADE`. The store has no `remove_resource()` method
+//!     because it isn't needed: deleting the file/folder row reaps the
+//!     attached dead properties as a database invariant.
+//!   * MOVE / RENAME never changes the resource id, so dead properties
+//!     follow the resource without any store-side bookkeeping. The store
+//!     has no `rename_resource()` method for the same reason.
+//!   * Dead properties are RESOURCE state (RFC 4918 §4.2), not user
+//!     state. Two users on a shared drive PROPFIND'ing the same resource
+//!     see the same dead properties. The `user_id` scope key from the
+//!     pre-rekey schema is gone; user-delete cleanup happens
+//!     transitively through `auth.users` → `storage.{folders,files}` →
+//!     this table.
+//!
+//! Queries use `sqlx::query()` (runtime-bound) rather than `sqlx::query!()`
+//! to keep fresh checkouts compilable without a DB connection — the
+//! codebase's standing convention.
+//!
+//! COPY semantics (RFC 4918 §8.8 — dead properties MUST be duplicated)
+//! are NOT handled here. The COPY handler is responsible for explicitly
+//! reading the source's dead properties via `get_all()` and writing them
+//! against the new resource id via `set()`. Not done in this migration —
+//! it was not handled by the path-based store either, so this is a
+//! parity decision, not a regression.

+/// mutation for **shared** drives (D4).
+///
+/// Personal drives are refused with `400 InvalidInput` — their
+/// effective cap comes from the owner user's
+/// `users.storage_quota_bytes` envelope (memory
+/// `project_user_envelope_quota_model`); use
+/// `PUT /api/admin/users/{id}/quota` instead. Allowing a per-personal-
+/// drive quota here would fork the model into two competing paths.
+///
+/// Non-admin callers receive `404` (anti-enumeration — same shape as
+/// "no such drive", so a probe can't distinguish "drive doesn't
+/// exist" from "quota edit is admin-only"). Matches the pattern
+/// established by `update_drive_policies` above.
+///
+/// **Soft-quota semantic on reduction.** A newly-lowered quota may
+/// land BELOW the drive's current `used_bytes`. The write succeeds;
+/// `storage_usage_service` then blocks new writes on
+/// `used + delta > quota`, so owners of a shared drive that's now
+/// over its freshly-reduced cap can only shrink (delete) until they
+/// come back under. Existing content is never retroactively touched
+/// — matches xfs `xfs_quota` / ext4 `edquota` behaviour on quota
+/// shrink.
+///
+/// Cache invalidation: the repo drops `readable_cache` +
+/// `default_drive_cache` (both embed the whole drive row incl.
+/// `quota_bytes`), matching the `update_policies` pattern.
+///
+/// Audit: emits `drive.quota_changed` with `new_quota_bytes`,
+/// `used_bytes`, and `over_quota` — so an operator grepping
+/// `audit drive.quota_changed` can spot a shrink that landed the
+/// drive in the over-quota delete-only state.

+# OxiCloud — magic-link login for password users
+# =============================================================
+# Regression pin for the `OXICLOUD_AUTH_POLICIES=permit_magic_link_for_password_users`
+# switch. Default eligibility ladder refuses `has_password` accounts
+# (the strict argument: mailbox-strength shouldn't shadow the stronger
+# credential). Operators who prefer modern-SaaS UX opt-in via this
+# policy; when set, `POST /api/auth/magic-link/send` mints a login token
+# for accounts that also have a password.
+#
+# Cross-file coupling: `tests/common/server.env` sets
+# `OXICLOUD_AUTH_POLICIES=permit_magic_link_for_password_users`. Without
+# it, Step 2 below would land on `reason="has_password"` and mail nothing
+# — Step 3's SMTP capture would fail with an empty inbox.
+#
+# What is NOT exercised here:
+#   * OIDC-master rule: covered separately in tests/oidc/oidc.hurl
+#     step 2b (magic-link SEND refused when OIDC is enabled).
+#   * `has_password` rejection under the strict default: can't be
+#     exercised in the same run — the env is global. Rust unit test
+#     on `magic_link_eligibility()` covers it directly.

+# OxiCloud — CalDAV calendar-query REPORT time-range regression
+# =============================================================
+# Regression pin for the time-range parser fix on
+# fix/caldav-time-range-parser.
+#
+# Pre-fix: caldav_adapter.rs::parse_report used
+# `DateTime::parse_from_rfc3339` on the `<C:time-range start="..."
+# end="..."/>` attribute values. That parser expects
+# `YYYY-MM-DDTHH:MM:SSZ` (dashes + colons). CalDAV clients send
+# iCalendar DATE-TIME format (`YYYYMMDDTHHMMSSZ` — no separators)
+# per RFC 4791 §9.9 / RFC 5545 §3.3.5. Result: parse silently
+# failed, `time_range` was `None`, and the REPORT handler fell
+# through to `list_events`, returning the ENTIRE calendar
+# regardless of the requested window.
+#
+# Post-fix: `parse_caldav_datetime` accepts iCal DATE-TIME
+# (the standard) with RFC 3339 as a defensive fallback. Time-
+# range filters now actually filter.
+#
+# Test shape: create two events at 09:00 UTC and 15:00 UTC, then
+# calendar-query REPORT with an iCal-DATE-TIME window covering
+# only the 09:00 event. Assert the response contains the 09:00

+# OxiCloud – CalDAV recurring events with RECURRENCE-ID overrides
+# =============================================================
+# End-to-end regression for AtalayaLabs/OxiCloud#528.
+#
+# Pre-fix behaviour (all-day recurring event, one occurrence
+# modified in Thunderbird/Apple Calendar/DAVx⁵/Gnome Calendar):
+#   * The client PUTs a VCALENDAR containing the master (with
+#     RRULE) + a per-instance override (RFC 5545 §3.8.4.4,
+#     `RECURRENCE-ID`). Pre-fix the substring-based parser
+#     could not read any property carrying parameters
+#     (`DTSTART;VALUE=DATE:...`, `RECURRENCE-ID;VALUE=DATE:...`),
+#     so all-day master modifications 500'd outright.
+#   * Even for timed events, the old create_event_from_ical
+#     read only the first VEVENT — a second PUT of just the
+#     exception would overwrite the master row entirely,
+#     silently corrupting the client's view of the series.
+#
+# Post-fix (this file's invariant):
+#   1. Master PUT → 201 CREATED, one row (recurrence_id NULL).
+#   2. PUT master + exception in one body → both persist to
+#      their own row keyed by (calendar_id, ical_uid,
+#      recurrence_id). Response is 201 CREATED because the
+#      exception was newly inserted.
+#   3. PUT ONLY the exception with modified content → 204
+#      No Content (in-place replace, no new rows). CRITICALLY,
+#      the MASTER row survives untouched — a GET on the .ics
+#      URL still returns the master's original RRULE + summary.
+#   4. All-day master + all-day exception (the exact #528 shape)
+#      completes the same round-trip.
+#
+# Storage invariant enforced by two partial unique indexes on
+# caldav.calendar_events (see migration 20260913000001):
+#   * idx_calendar_events_master_unique — at most one master
+#     per (calendar_id, ical_uid).

+#     route through `CalendarService`, which enforces
+#     `authz.require` on every method.
+#   * Cross-user access uses the 404 anti-enum shape (was 403
+#     in the bespoke `check_calendar_access` era).
+#   * Sharing goes through the generic `POST /api/grants` with
+#     `resource.type = "calendar"` — a first-class ReBAC
+#     resource variant added in Round 3 Phase 1.
+#   * A shared calendar shows up in the recipient's PROPFIND
+#     listing while the grant is live and disappears again
+#     after revoke.
+#
+# The `calendar_id` is server-assigned at MKCALENDAR time and
+# surfaces in the PROPFIND response as `/caldav/<uuid>/`. We
+# extract it with a regex on the response body — the fresh CI
+# database (`tests/webdav/run.sh` spawns a private Postgres)
+# guarantees admin has zero pre-existing calendars, so the
+# first-match regex is unambiguous.
+#

+#
+# `contact_service.rs::parse_vcard` had two independent gaps
+# and one case-sensitivity issue on the TYPE parameter:
+#
+#   1. TEL used `split(':').nth(1)` — a URI-form value like
+#      `TEL;TYPE=cell;VALUE=uri:tel:+15551234567` was sliced
+#      down to `"tel"`, losing the phone number entirely.
+#   2. ADR had no parser branch at all — every address was
+#      silently dropped at PUT time.
+#   3. TYPE param matching was case-sensitive; real clients
+#      (Apple Contacts, DAVx⁵, python-caldav) mix cases so
+#      `TYPE=cell` fell through to "other" instead of "mobile".
+#
+# Post-fix: `splitn(2, ':')` + `tel:` scheme strip, an ADR
+# branch parsing the 7-part structured value into (street,
+# city, state, postal_code, country), and case-insensitive

+# OxiCloud — DAV error-shape regression pin
+# =============================================================
+# Regression pin for the second half of AtalayaLabs/OxiCloud#545 (the
+# funboytwo comment): the CalDAV/CardDAV handlers used to blanket-wrap
+# every domain error as `AppError::internal_error(...)`, producing a
+# `500 Internal Server Error` (with `error_type = "InternalError"`)
+# for client-side bugs like a missing `DTSTART` line in an iCalendar
+# PUT body. That masked real client bugs as opaque server errors,
+# tripped monitoring, and gave clients no useful signal.
+#
+# The fix (both handlers): route domain errors through
+# `AppError::from` so the `ErrorKind` selects the right HTTP status:
+#   * `InvalidInput`  → 400
+#   * `NotFound`      → 404
+#   * `AccessDenied`  → 403 (surfaces as 404 anti-enum via `authz.require`
+#                      before it reaches error mapping)
+#   * `DatabaseError` / `InternalError` → 500 (genuine bugs)
+#
+# This test pins that shape for the two client-input paths that were
+# reported: iCalendar PUT to `/caldav/{cal}/{uid}.ics` and vCard PUT
+# to `/carddav/{book}/{uid}.vcf`. Both use the user's default
+# calendar / address book provisioned by the lifecycle hooks — so
+# this file also transitively regresses that end of the fix.

+# OxiCloud — Dedup admin gate + URL move
+# =============================================================
+# Regression pin for AuthZ audit #24 + #25 (2026-07-12).
+#
+# `dedup_handler.rs` previously rolled its own admin check on
+# `/api/dedup/stats` and `/api/dedup/recalculate` — a bespoke
+# `if auth_user.role != "admin" { 403 with hand-rolled JSON }`
+# with no audit line on rejection. That's the same drift class
+# the admin middleware layer refactor closed elsewhere on
+# 2026-07-17.
+#
+# Fix:
+#   1. Both endpoints moved to `/api/admin/dedup/*` where the
+#      `/api/admin` middleware gate covers them by construction.
+#      URL declares admin intent up front.
+#   2. Inline role check removed from the handlers — reaching
+#      them at all means the caller is admin.
+#   3. `recalculate` emits `dedup.integrity_recalculated` on
+#      success (audit #25). Not asserted here (no log-scrape
+#      harness in Hurl); the shape is pinned in the handler
+#      code and covered by the `audit` tracing target contract.
+#
+# This test pins:
+#   * Admin can hit both endpoints at the new URL → 200.
+#   * Non-admin (bob) hits both → 403 (middleware layer).

+# =============================================================
+# Run:

+#        --test tests/api/drive_policies.hurl
+#
+# The model under test (`docs/plan/drive.md` §8):
+#   Each drive carries a `policies` JSONB. Five known keys, all
+#   default-false. The first key shipped is `forbid_public_links`,
+#   which blocks anonymous token-share creation on every resource
+#   in the drive. Enforced at `share_service::create_shared_link`;
+#   mutated by `PATCH /api/drives/{id}/policies` (OxiCloud-admin
+#   only — the carve-out closes the self-policing-soft-cap hole
+#   where an owner could disable a policy, share, and re-enable).
+#
+# Cases:
+#   1. Baseline — policy off → POST /api/shares succeeds (201).
+#   2. Owner flips `forbid_public_links` via PATCH → 200,
+#      response echoes the merged bag.
+#   3. Policy on → POST /api/shares refused with
+#      OperationNotSupported (405) and the share row is NOT created.
+#   4. Owner flips the policy back off → POST /api/shares succeeds
+#      again (proves merge semantics; the typed write doesn't
+#      clobber unrelated keys).
+#
+# Self-contained: provisions `dp_owner` so it can run alongside
+# the rest of the suite. The user's default Personal drive is
+# the test surface — the policy applies equally to personal and
+# shared drives (`Owner` bundle includes "edit policies").

+# Pins the upload-time per-drive quota refusal. Scope:
+#
+#   1. Quota = 100 B on a shared drive; uploading a 5 MiB file →
+#      `507 Insufficient Storage`. Refusal happens BEFORE the file
+#      row is registered (no orphan blob, no usage drift).
+#   2. A small file (32 B) under the same quota → `201`. The fire-
+#      and-forget delta hook bumps `drives.used_bytes`; the next
+#      `GET /api/drives` lists the new value.
+#   3. After consuming most of the quota, a second small file that
+#      would push us over → `507`. Confirms the check uses the
+#      cached `used_bytes`, not just file size in isolation.
+#   4. Unlimited quota (`quota_bytes` omitted at create) accepts the
+#      same 5 MiB upload that case 1 refused → `201`.
+#   5. Per-user quota is unaffected — uploading to the user's own
+#      default Personal drive (no per-drive cap) still works.
+#
+# The check is layered on top of the existing per-user quota
+# (`storage_usage_service::check_storage_quota`) — both run at the
+# multipart handler; either refusal yields 507.

+#
+# The model under test (`docs/plan/drive.md` §8):
+#   `policies.read_only = true` on any drive refuses EVERY mutating
+#   permission (Create / Update / Delete / Share / Comment / Manage)
+#   on resources in that drive — from user-initiated paths AND
+#   background jobs alike. Only `Read` passes. The admin escape
+#   hatch is separate: `PATCH /api/drives/{id}/policies` is gated
+#   by `admin_guard` at the handler layer and bypasses the engine's
+#   authz.require entirely, so admins can always un-freeze.
+#
+# Enforcement points exercised here:
+#   - `PgAclEngine::check_inner` on File/Folder resources (drive
+#     precheck branch, mutating permission → refused before role
+#     lookup even runs).
+#   - `PgAclEngine::check_inner` on Drive resources (same gate).
+#   - `share_service::create_shared_link` — goes through
+#     `authz.require(Share, Resource::File)` → engine gate fires.
+#   - Trash purge SQL — proven separately by the SQL predicate
+#     landing in `trash_db_repository::delete_expired_bulk` (not
+#     exercised at the HTTP layer here — requires a controllable
+#     retention clock; see comment in Step 12).
+#
+# Cases:
+#   1. Baseline — drive not frozen → owner can upload / rename /
+#      delete / trash / share (proves the fixture is writable).
+#   2. Admin freezes the drive via PATCH policies.
+#   3. Every mutation attempt is refused. The engine's graduated
+#      denial returns 403 to the owner (who can Read their own
+#      drive) — anti-enum only kicks in for callers with no Read
+#      at all, whose 404 shape is exercised by the cross-tenant
+#      tests in `webdav_permissions.hurl` / `permissions.hurl`.
+#      Cases: upload, rename, delete, trash-restore, permanent
+#      delete, create public link, rename the drive itself.
+#   4. Read still works: GET /api/drives, GET /api/folders,
+#      download the file, list trash.

+# OxiCloud — NC multi-drive MOVE destination-prefix regressions
+# =============================================================
+# Regression coverage for two sibling bugs discovered 2026-07-12
+# when the multi-drive `admin~{drive-uuid}` credential shape was
+# rolled through the NC `/remote.php/dav/*` surface but two MOVE
+# handlers were missed:
+#
+#   uploads_handler::handle_assemble (chunked-upload MOVE)
+#   trashbin_handler   (restore MOVE with a Destination header)
+#
+# Both handlers were stripping the destination-URL prefix with
+# `&user.username` (bare `admin`) instead of
+# `&session.raw_username` (composite `admin~{uuid}`). NC clients
+# on a non-home drive send:
+#     Destination: /remote.php/dav/files/admin~{uuid}/<path>
+# The bare-username strip left `~{uuid}/<path>` glued to the
+# leading path segment; downstream lookups then targeted a
+# fabricated `<drive-root>/~{uuid}/…` path and 500'd (assemble
+# path) or silently missed collisions (trash path).
+#
+# webdav_handler::handle_move (the standard `/dav/files/…` MOVE)
+# was ALREADY correct — it uses `url_user = &session.raw_username`.
+# The uploads + trashbin siblings were coverage gaps: no Hurl
+# tests hit them with a composite credential.
+#
+# Hurl gotcha: the `[BasicAuth]` block parses the username as a
+# single token terminated by `:`. A raw composite like
+# `{{nc_username}}~{{drive_id}}` fails to parse because Hurl
+# sees the `~` between two templates and expects a line
+# terminator. Workaround: alias the composite into
+# `nc_basic_user` via `[Options] variable:` on a bootstrap
+# request, then use `{{nc_basic_user}}` in every subsequent
+# BasicAuth block.

+# PROPPATCH/PROPFIND contract on the NextCloud-compatible surface
+# (`/remote.php/dav/files/{user}/...`), which — until now — had NO
+# generic dead-property support: PROPPATCH only special-cased
+# `oc:favorite` via an ad hoc XML scan and silently discarded any
+# other property while still claiming `200 OK`; PROPFIND always
+# emitted a fixed hardcoded property set with no dead-property
+# lookup at all. A client (or litmus) PROPPATCHing a custom label
+# through the NextCloud mount got a false success and then never
+# saw the property again.
+#
+# Coverage:
+#   1.  Setup: JWT login, mint an NC app password.
+#   2.  PUT a probe file via the NC DAV surface.
+#   3.  PROPPATCH set a custom property → 207.
+#   4.  PROPFIND → value round-trips verbatim.
+#   5.  PROPPATCH upsert (same name, new value) → PROPFIND confirms
+#       overwrite, not a duplicate row.
+#   6.  PROPPATCH remove → PROPFIND confirms absence.
+#   7.  PROPPATCH on a nonexistent resource → 404 (the tightened
+#       contract: PROPPATCH now does real work, so a previous
+#       "always claim success" no-op on a missing resource would be
+#       a foot-gun, not a feature).
+#   8.  Re-set a property, MOVE the file → PROPFIND on the new path
+#       still returns it (resource id is stable across MOVE).
+#   9.  DELETE, then PUT a fresh file at the same path → PROPFIND
+#       does NOT see the old marker (new resource, no leaked state).
+#   10. Regression guard: `oc:favorite` PROPPATCH/PROPFIND still
+#       works, unaffected by the refactor from the ad hoc favorite
+#       scanner to generic `WebDavAdapter::parse_proppatch`.
+#   11. Folder coverage: MKCOL, PROPPATCH a dead property on the

+# OxiCloud — NextCloud HTTP PATCH partial content updates (RFC 5789)
+# =============================================================
+# The NextCloud-compatible WebDAV surface (/remote.php/dav/…) had no
+# PATCH dispatch arm at all (fell through to 405), unlike the plain-file
+# surface (see api/handlers/webdav_handler.rs::handle_patch). See
+# nextcloud/webdav_handler.rs::handle_patch, which reuses the plain
+# surface's `parse_update_range` and `upload_ingest::
+# ingest_range_patch_to_cas` — both surface-agnostic.
+#
+# Coverage:
+#   1. PATCH an explicit byte range (`X-Update-Range: bytes=<start>-<end>`)
+#      → 204, Content-Range header, and the resulting content reflects
+#      the patched span with the untouched prefix/suffix intact.
+#   2. PATCH with `X-Update-Range: append` → 204, content grows.
+#   3. PATCH with a Content-Range header → 400 (must use X-Update-Range).
+#   4. PATCH without X-Update-Range → 400.
+#   5. PATCH on a nonexistent file → 404.
+#   6. PATCH on a directory → 409 (not 404 — the NC surface previously
+#      had no folder-existence check and returned 404 for both a missing
+#      file AND an existing directory; the fix commit added an explicit
+#      check so the two cases are distinguishable again, matching the
+#      plain-surface behavior).
+#
+# Hurl gotcha: headers MUST come before section blocks like
+# `[BasicAuth]` in a request — a header line placed after `[BasicAuth]`
+# is parsed as the START OF A NEW REQUEST instead (see
+# `nc_multidrive_move_regression.hurl`'s note on the same gotcha).

+# =============================================================
+# OxiCloud — NextCloud PATCH data-consistency + authz/lock gaps
+# =============================================================
+# `nc_webdav_patch.hurl` covers the PATCH contract on the NC surface.
+# This file targets the specific gaps closed by the review-fix commit
+# (see nextcloud/webdav_handler.rs::handle_patch):
+#
+#   1. AuthZ: the NC surface previously called `get_file_by_path`
+#      (which performs NO authorization check) with no follow-up
+#      `authz.require` at all — any caller with a valid app password
+#      could learn a file's size/ETag via PATCH's precondition/range
+#      responses regardless of their actual permission on that file.
+#      The fix added the same `Permission::Read` check the plain
+#      surface already had. That Read check is only an early
+#      existence-proof gate, though — the actual write a few lines
+#      later goes through `update_file_streaming_with_perms`, which
+#      independently requires `Permission::Update`. So the full
+#      permission chain for PATCH is: EDITOR (has Update) can PATCH;
+#      VIEWER (Read only, no Update) gets past the early gate but is
+#      still denied — anti-enum 404 — at the write step; a caller
+#      with NO grant at all can't even establish the composite-marker
+#      chroot. Tested via the multi-drive composite `{user}~{folder_id}`
+#      credential shape (see `nc_multidrive_move_regression.hurl` for
+#      the mechanism).
+#   2. Cross-surface lock interop: a LOCK taken via the plain
+#      `/webdav/` surface now also blocks PATCH via `/remote.php/dav/`
+#      for the same file — proves the two surfaces share one lock
+#      store, not two independent ones.
+#   3. Quota/507 via the NC surface (previously missing entirely —
+#      the fix added the same per-user quota check the plain surface
+#      already enforced), and the failed PATCH leaves the file intact.
+#
+# Self-contained: provisions its own throwaway users/drive so it can
+# run alongside the rest of the suite.

+# OxiCloud — NextCloud PUT gaps closed by bringing handle_put up to
+# parity with handle_patch
+# =============================================================
+# `nc_webdav_patch_consistency.hurl` covers the same four gap classes
+# for PATCH; this file targets the NC surface's `handle_put`
+# (nextcloud/webdav_handler.rs), which had fallen behind PATCH's
+# hardening across the RFC 5789 commits:
+#
+#   1. Error mapping: the write step mapped every `DomainError` to a
+#      raw 500 (`AppError::internal_error(format!("Failed to store
+#      file: {}", e))`) instead of `AppError::from(e)` — a VIEWER
+#      (Read only, no Update) overwriting a file got a 500 leak
+#      instead of the graduated-denial 403 the rest of the codebase
+#      relies on (Read granted → visible → 403; no Read at all →
+#      hidden → 404 anti-enum).
+#   2. Cross-surface lock interop: PUT via `/remote.php/dav/` didn't
+#      consult the lock store a LOCK taken via the plain `/webdav/`
+#      surface writes to at all.
+#   3. Quota/507: PUT via the NC surface bypassed
+#      `check_storage_quota` entirely (PATCH already enforced it).
+#   4. Existence-check depth (RFC 4918 §9.7.1): PUT to an existing
+#      directory should be 400, and PUT under a missing parent folder
+#      should be 409 — neither check existed on the NC surface; both
+#      failure modes fell through to whatever `update_file_streaming_
+#      with_perms` did internally.
+#
+# Self-contained: provisions its own throwaway users/drive so it can
+# run alongside the rest of the suite.

+# The NextCloud-compatible WebDAV surface

+# `d:quota-used-bytes`/`d:quota-available-bytes` support at all. This
+# pins the new coverage added alongside the native surface's
+# drive-awareness fix (`AppState::resolve_webdav_quota`):
+#
+#   1. Personal-drive PROPFIND (no drive marker in the Basic Auth
+#      username) reports the caller's account envelope.
+#   2. A SHARED drive with its own finite quota reports THAT quota —
+#      not the owner's personal envelope — when addressed via the
+#      multi-drive POC's `{user}~{root_folder_id}` Basic Auth marker
+#      (see `basic_auth_middleware.rs` — the marker is the drive's
+#      ROOT FOLDER id, not the drive's own id).
+#   3. quota-used-bytes on the shared drive increases after a PUT.
+#
+# This file always emits the full property set regardless of the
+# PROPFIND request body (see `handle_propfind`'s doc comment — "the

+#       - Legacy `POST /api/playlists/{id}/share` (bool `can_write`)

+#         `authz.set_role`, so both flows converge on the unified

+# =============================================================
+# Regression #595 — Admin-created user with quota=0 ("unlimited"
+# per UI convention) must be able to upload.
+# =============================================================
+# Pre-fix behaviour (documented in the issue):
+#
+#   1. Admin creates user with `quota_bytes: 0` (meaning "unlimited"
+#      per the check-code convention: `check_storage_quota` treats
+#      `quota <= 0` as unlimited).
+#   2. `PersonalDriveLifecycleHook::create_personal_drive_atomic` was
+#      called with `Some(user.storage_quota_bytes())` — so
+#      `storage.drives.quota_bytes` on the new personal drive was
+#      stamped `0`.
+#   3. On upload, the drive-quota check (`check_drive_quota_by_folder`)
+#      reads `drives.quota_bytes = 0`, interprets Some(0) as a literal
+#      zero-byte cap (its NULL check only accepts `None` as unlimited),
+#      and rejects with 507 Insufficient Storage.
+#
+# The two conventions collided: user-quota "0 = unlimited" vs
+# drive-quota "0 = literal zero, NULL = unlimited". Documented as
+# a spec violation of docs/plan/drive.md §7: "For personal drives
+# this column is NULL … the effective cap comes from the user
+# envelope."
+#
+# Fix (three parts, this test guards all three):
+#   1. `folder_service.rs:927` — pass `None`, never `Some(user quota)`.
+#   2. Migration `20260916000000_null_personal_drive_quota.sql` —
+#      NULL every existing personal drive's `quota_bytes` (data heal).
+#   3. Same migration — CHECK constraint pinning
+#      `kind <> 'personal' OR quota_bytes IS NULL` at the DB layer.
+#
+# This scenario reproduces the bug against a fresh user and asserts
+# the upload succeeds (Fix 1 evidence) AND the personal drive's
+# `quota_bytes` field is absent from the wire (`Option::is_none`
+# serde-skip → `quota_bytes` key missing = Fix 1 + migration evidence).

+# per-drive variant of `DELETE /api/trash/empty`. Scope of coverage:
+#
+#   1. Owner of a drive CAN empty that drive's trash → 204.
+#   2. Idempotent: calling again on an empty drive still returns 204.
+#   3. Scope: emptying drive A leaves drive B's trash intact.
+#   4. Viewer of a shared drive → 404 (Viewer's bundle has no Delete).
+#   5. Editor of a shared drive → 404 (Editor's bundle has no Delete).
+#   6. Non-member of a shared drive → 404 (anti-enum).
+#   7. Unknown drive UUID → 404 (same shape as no-role case; can't
+#      enumerate drive existence through this endpoint).
+#

+# (scope) is the load-bearing assertion against a regression that

+# OxiCloud — auth.users.ui_preferences round-trip
+# =============================================================
+# The `ui_preferences` JSONB column is the SPA's cross-device
+# backing store for pure UI toggles (hide dotfiles, view mode,
+# sidebar collapse, …). The server treats the contents as
+# opaque; this suite pins the semantics of the PATCH surface
+# so a future refactor can't silently break cross-device sync:
+#
+#   1. Fresh user starts with an empty object bag (`{}`), not
+#      `null` and not missing from the response body.
+#   2. PATCH does a SHALLOW merge — a partial write only
+#      touches the keys it mentions; siblings survive. Load-
+#      bearing invariant: without it, Device A's write would
+#      silently wipe preferences Device B just set.
+#   3. Sending `{key: null}` in the patch REMOVES that key
+#      server-side (jsonb_strip_nulls after the merge). This
+#      is the documented delete-a-key path.
+#   4. Non-object patch shape is rejected with 400. Prevents
+#      the endpoint from being a scratch scalar store and
+#      catches malformed clients early.
+#
+# Not covered here (intentional):
+#   • 16 KiB size cap — the CHECK is at the schema layer and
+#     is exercised by unit tests without needing an integration
+#     round-trip; constructing a 16 KiB JSON body in Hurl adds
+#     line noise without meaningful signal.
+#   • Concurrency safety of the shallow merge under two

+# Coverage:
+#   1.  Setup admin, capture JWT, PUT a probe file.
+#   2.  PROPPATCH set → 207
+#   3.  PROPFIND get → value round-trips verbatim
+#   4.  PROPPATCH upsert (set same name → new value) → 207
+#   5.  PROPFIND get → new value (upsert worked)
+#   6.  PROPPATCH remove → 207
+#   7.  PROPFIND get → property absent
+#   8.  MOVE file → properties follow the resource id automatically
+#       (no rename_resource() call; the row's file_id is stable
+#       across MOVE so dead-props travel with the resource).
+#   9.  PROPFIND on moved path returns the property.
+#   10. DELETE via WebDAV → FK CASCADE reaps dead-prop rows.
+#   11. PROPPATCH + REST DELETE `/api/files/{id}` → FK CASCADE
+#       reaps via the REST-side delete path too. This is the
+#       new coverage unlocked by migration 20260830000001 — the
+#       old path-keyed store had no way to clean up here, so
+#       the SvelteKit web UI (which deletes via REST) was
+#       silently leaking tombstones every time a user deleted
+#       a file that had ever carried dead properties.
+#   12. Folder MOVE preserves dead properties (id-stable
+#       guarantee under rename). The Hurl suite had no folder-
+#       side coverage of this until 20260830000001; only the
+#       file MOVE case (step 9) was guarded.
+#   13. Single-file COPY duplicates dead properties (RFC 4918
+#       §8.8). Destination carries a copy of the source's
+#       marker; source retains its copy (COPY ≠ MOVE).
+#       Implementation: `dead_prop_copy` CTE branch in
+#       `copy_file` (migration 20260830000002).
+#   14. Folder COPY (Depth: infinity) duplicates dead
+#       properties for every descendant — both folder and file
+#       dead-props. Implementation: the two INSERT...SELECT
+#       branches in `storage.copy_folder_tree` (migration
+#       20260830000002) that walk `_copy_map` and the new
+#       `_copy_file_map` respectively.
+#
+# XPath assertions deliberately use `local-name()` so the test
+# is robust against the server's choice of namespace prefix —
+# DeadPropertyStore generates `X:` but a future implementation
+# is free to pick something else as long as `xmlns:X` is correct.

+#
+#   Default deployment (`OXICLOUD_WEBDAV_DRIVE_LISTING_PREFIX="@drive"`):
+#     * `/webdav/`                       → default drive's contents

+#     * `/webdav/@drive/<name>/…`        → explicit drive by name
+#
+# Coverage:
+#   1. Login, capture JWT
+#   2. Resolve caller's default drive (id + display name)
+#   3. Create a magic folder under the home root via REST
+#   4. PROPFIND `/webdav/` — Depth: 1 lists the magic folder as
+#      an immediate child of the default drive. This is the
+#      user-visible bug fix: pre-refactor, `/webdav/` returned a
+#      drive listing instead of the default drive's contents.
+#   5. PROPFIND `/webdav/@drive/` — Depth: 1 lists each drive as
+#      a virtual child (at least the caller's default is present).

+# OxiCloud — WebDAV: nested-folder MOVE descendant cascade
+# =============================================================
+# Regression guard for the litmus `copymove → move_coll`
+# scenario: when a parent folder is renamed (or moved), every
+# DESCENDANT folder row must have its `path` / `lpath` columns
+# rewritten by the AFTER cascade trigger
+# `trg_folders_cascade_path` so that path-keyed lookups
+# (WebDAV, CalDAV, CardDAV, and a handful of REST endpoints)
+# resolve the descendant at its new location.
+#
+# Why this needs a dedicated test:
+#   * REST API tests overwhelmingly use folder IDs, not paths —
+#     a stale `folders.path` column is invisible to `WHERE id =
+#     $1` lookups. So they can't catch this regression even when
+#     they MOVE.
+#   * Existing WebDAV tests are flat: MOVE a file, or MKCOL +
+#     DELETE on a single-level folder. None combine "MOVE a
+#     folder that has folder descendants" with "look the
+#     descendant up by its post-move path".
+#   * litmus's `copymove → move_coll` IS this test, but litmus
+#     isn't installed on every contributor's machine — it lives
+#     on the CI side only. This Hurl scenario runs in every
+#     standard `just api-test`.
+#
+# Bug shape it catches: the `UPDATE OF <cols>` column list on
+# `trg_folders_cascade_path` must include `name` AND `parent_id`
+# (not just `path, lpath, drive_id`) — otherwise the AFTER
+# trigger never fires on the rename SQL `UPDATE folders SET
+# name = $1` or the move SQL `UPDATE folders SET parent_id =
+# $1`, descendant rows stay at their pre-move path, and any
+# subsequent path-keyed lookup of a descendant returns 404.
+#
+# What this test does:
+#   1. Login (admin).
+#   2. MKCOL  /webdav/regress-cascade-a/
+#   3. MKCOL  /webdav/regress-cascade-a/b/        (descendant folder)

+#   5. MOVE   /webdav/regress-cascade-a/ → /webdav/regress-cascade-c/

+# OxiCloud — WebDAV PATCH (RFC 5789) partial content update
+# =============================================================
+# RFC 4918 §9.7.1 forbids partial updates on PUT (a `Content-Range`
+# on PUT is rejected, see webdav_handler.rs::handle_put). PATCH is
+# the mechanism this server offers instead, via a dedicated
+# `X-Update-Range` header: `bytes=<start>-<end>` (inclusive) or
+# `append`. See webdav_handler.rs::handle_patch /
+# parse_update_range for the implementation.
+#
+# Coverage:
+#   1. Mid-file byte-range overwrite → 204, GET reflects the splice.
+#   2. Append → 204, GET reflects the appended tail.
+#   3. Out-of-range span (end >= size) → 416.
+#   4. If-Match precondition failure → 412.
+#   5. Locked resource without a lock token → 423.
+#   6. PATCH on a directory → 409.
+#   7. PATCH on a missing resource → 404.
+#   8. PATCH without X-Update-Range → 400.
+#   9. If-None-Match precondition failure (tag matches current ETag) → 412.
+#  10. If-Match with a WEAK (`W/`) form of the current ETag → 412 (RFC 7232
+#      §3.1: If-Match requires a STRONG match; a weak validator in the
+#      request never satisfies it, even if the underlying tag value is
+#      identical — see `if_match_precondition_fails`).
+#
+# Hurl gotcha: a triple-backtick ``` multiline body appends a trailing

+# the concern behind the review-fix commit that added quota
+# enforcement, an ETag re-check, and a `direct_put_max_bytes`
+# prefix/suffix accounting bug (see webdav_handler.rs::handle_patch).
+#
+# Coverage:
+#   1. Sequential overlapping-range PATCHes on one file: each step's
+#      GET reflects the splice, and the ETag changes every time (no
+#      stale-tag reuse across writes).
+#   2. Cross-protocol consistency: HEAD and PROPFIND report the same
+#      size/ETag as the GET right after the last PATCH.
+#   3. Quota rejection (507) leaves the file BYTE-FOR-BYTE unchanged —
+#      the ingested blob is discarded before it's ever attached
+#      (`upload_ingest::discard_ingested`).
+#   4. `direct_put_max_bytes` bounds only the EDIT span, not the whole
+#      file: a small edit on a file already bigger than the cap still
+#      succeeds, but an edit whose OWN body exceeds the cap still 413s.

+#      hiding existence from someone already reading it. A caller with
+#      no Read at all gets 404 (anti-enum), matching "no such folder".
+#
+#   2. Drive policy `forbid_cross_drive_move` gates MOVE at the
+#      SOURCE drive (see `DrivePolicies::refuse_cross_drive_move`
+#      in `src/domain/entities/drive.rs`) — even a fully-authorised
+#      Editor can't move content OUT of a drive whose owner has

+#
+# Assumes the default `OXICLOUD_WEBDAV_DRIVE_LISTING_PREFIX="@drive"` config —

+# =============================================================
+# OxiCloud — WebDAV protected properties (RFC 4918 §9.2 / §15)
+# =============================================================
+# `DeadPropertyStore` lets a PROPPATCH set arbitrary namespace/name
+# pairs verbatim (RFC 4918 §4.2). Without a denylist, a client could
+# PROPPATCH `DAV:getetag`, `oc:fileid`, `oc:permissions`, etc. — names
+# the server ALSO emits as live state in PROPFIND/REPORT responses
+# (see `write_file_response` / `write_folder_response` in the NC
+# handler and the native PROPFIND writer). That produces either a
+# forged live property (the server would need to pick which of two
+# values to emit) or a silently stored, never-read row.
+#
+# `is_protected_property()` (src/application/adapters/webdav_adapter.rs)
+# defends the whole `DAV:` namespace plus the specific oc:/nc:/ocs:
+# names the server actually emits elsewhere. Both PROPPATCH handlers
+# (native `/webdav/` and NC `/remote.php/dav/`) consult it before
+# touching `DeadPropertyStore`, and reject with RFC 4918 §9.2's
+# per-property `403 Forbidden` inside the 207 multi-status — not a
+# blanket request failure, and not a silent no-op success.
+#
+# Coverage:
+#   1.  Native /webdav/: PROPPATCH set on `D:displayname` (DAV:
+#       namespace) → 207 envelope, inner 403 for that property.
+#   2.  PROPFIND confirms the live displayname is unchanged — the
+#       forged value never landed anywhere.
+#   3.  Native /webdav/: PROPPATCH remove on `D:getetag` → same 403
+#       contract on the Remove path, not just Set.
+#   4.  Native /webdav/: an oc:-namespaced protected name
+#       (`oc:fileid`) is blocked even on the surface that doesn't
+#       normally speak NextCloud namespaces — protection is
+#       namespace-global, not surface-scoped.
+#   5.  Mixed request: one protected DAV: prop + one ordinary custom
+#       dead property in the SAME PROPPATCH → 207 with both a 403
+#       propstat block and a 200 propstat block; the custom property
+#       DOES get stored (per-property granularity, not all-or-nothing
+#       rejection).
+#   6.  NC surface: PROPPATCH set on a protected oc: name
+#       (`oc:permissions`) → 403; PROPFIND confirms it was never
+#       written to the dead-property store.
+#   7.  NC surface: PROPPATCH set on a protected nc: name
+#       (`nc:has-preview`) → 403.
+#   8.  Regression guard: `oc:favorite` is on the protected list too
+#       (it's live state the NC handler emits), but the handler's
+#       favorite special-case runs BEFORE the protected-property
+#       check, so toggling favorite through PROPPATCH still works —
+#       protection must not swallow the one oc: name that's
+#       legitimately client-writable via a side channel.

+# OxiCloud — WOPI authorization at token redemption
+# =============================================================
+# Regression coverage for the WOPI verb-handler bypass documented in
+# memory note `wopi-authz-bypass`. Two bugs closed:
+#
+#   1. Verb handlers (check_file_info, get_file, put_file,
+#      file_operations, host_page) previously did NOT call
+#      `AuthorizationEngine::require` at redemption. A grant
+#      revoked between mint-time and request-time silently kept
+#      working until the token TTL expired.
+#
+#   2. The mint helper decided `can_write` from the client's
+#      `requested_action` string (`!= "view"` → write). A Viewer
+#      clicking "Edit in Collabora" received a write-capable
+#      token because the string was "edit".
+#
+# The fix wires `authz.require` on every verb and derives
+# `can_write` from the caller's actual Update permission. This
+# suite hits both paths through the real HTTP surface.
+#
+# Note on infra:
+#   * `OXICLOUD_WOPI_ENABLED=true` in tests/common/server.env
+#   * `OXICLOUD_WOPI_SECRET` pinned so the tokens the server mints
+#     round-trip verify-able through the suite
+#   * WOPI discovery served by `tests/common/wopi_mock_discovery.py`
+#     started by run.sh — mock URL points at a black-hole editor
+#     so we only assert on OxiCloud's own responses

+# =============================================================
+# OxiCloud — WOPI PutFile against a shared drive
+# =============================================================
+# Regression pin for AuthZ audit #18 (2026-07-12).
+#
+# `wopi_handler.rs::put_file` used to resolve the write's target
+# drive via `drive_repo.find_default_for_user(claims_sub_uuid)` —
+# ALWAYS the caller's own default personal drive, regardless of
+# where the file being edited actually lived. Consequences for a
+# shared-drive file:
+#
+#   - If the file's path happened to collide with a personal-drive
+#     path, the write MISROUTED into the caller's personal drive
+#     (silent cross-drive data ejection).
+#   - Otherwise the parent-folder lookup inside
+#     `update_file_streaming_with_perms` missed and the request
+#     500'd — a UX brick on shared-drive WOPI editing.
+#
+# Fix: resolve `drive_id` from the FILE's own parent folder via
+# `drive_repo.drive_id_for_folder(file.folder_id)`. Same file →
+# same drive → write lands in the shared drive it belongs to.
+#
+# This test:
+#   1. Admin creates a shared drive (D3a shape).
+#   2. Admin uploads `hello.txt` to the shared drive's root.
+#   3. Admin mints a WOPI edit token.
+#   4. Admin PutFile with fresh content → 200.
+#      Pre-fix this 500'd because the personal-drive-scoped
+#      parent-folder lookup couldn't find a folder named "" in
+#      admin's personal drive.
+#   5. Admin GetFile → the shared drive holds the new content.
+#      Proves the write landed on the correct drive.
+#
+# Prereqs: `OXICLOUD_WOPI_ENABLED=true`, `OXICLOUD_WOPI_SECRET`

+"""CardDAV (RFC 6352) surface coverage.
+
+python-caldav has no CardDAV support (the library name is a bit
+misleading — it's CalDAV-only). These tests drive the server via
+raw HTTP through the SAME authenticated `dav_client` session used
+by the CalDAV tests, so credentials + connection reuse stay
+consistent with the rest of the suite.
+
+Fixtures:
+  * `carddav_url` — CardDAV base URL, derived from OXICLOUD_CALDAV_URL
+    by replacing `/caldav/` with `/carddav/`.
+  * `fresh_addressbook` — a brand-new address book per test; yields
+    the server-authoritative URL as a string; teardown DELETEs it.
+
+Coverage: the sanity tests cover the FN/N/EMAIL core; the
+extended round-trips (ORG/TITLE/NOTE/TEL/ADR) each pin a
+parser + emitter pair. Any regression that drops a property
+on the round-trip fails the corresponding test.
+
+The CardDAV emitter regenerates vCard bodies from stored DTO
+fields on GET — properties without a DTO field (BDAY, PHOTO,
+categories, custom X-*) still don't survive. Same emitter-gap
+class as `test_ical_coverage.py`; would be closed by serving
+the stored vcard_data verbatim or extending the DTO.

+"""Non-recurring iCalendar property coverage via python-caldav.
+
+Complements `test_recurring.py` (the #528 regression suite) by
+sweeping the property surface of a single, non-recurring VEVENT.
+Real CalDAV clients send many properties beyond DTSTART/DTEND +
+SUMMARY; whether those survive a PUT → GET round-trip is what
+this file measures.
+
+The GET path in `caldav_handler.rs::write_vevent` regenerates
+the response body from the stored DTO fields (UID / SUMMARY /
+DTSTART / DTEND / DESCRIPTION / LOCATION / RRULE / DTSTAMP /
+CREATED / LAST-MODIFIED). Anything not in that list is silently
+dropped even though the original `ical_data` is stored intact.
+
+Every test is a strict round-trip pin: PUT a vCalendar body
+carrying the property, GET the URL, assert the property is
+present in the response. Post-phase-4 the emitter serves each
+row's stored `ical_data` verbatim (folded per UID), so a
+regression on any property here means either the storage

+"""End-to-end regression for AtalayaLabs/OxiCloud#528 via python-caldav.
+
+The Hurl coverage in `tests/api/caldav_recurring.hurl` exercises the
+raw HTTP surface; this file drives the SAME behaviour through the
+python-caldav client library — the same VObject + RFC 5545 stack that
+Thunderbird, DAVx⁵ and Gnome Calendar use. If a real client's shape
+diverges from what our Hurl fixtures send, this suite catches it.
+
+Two access paths need distinguishing:
+
+  * URL GET on `/caldav/<cal>/<uid>.ics` — routes through
+    `find_event_by_ical_uid` which is master-only. This is what
+    single-file iCal clients (older Thunderbird, Apple Reminders'
+    quick-lookup) hit.
+
+  * calendar-query REPORT — returns every calendar-object-resource
+    matching the filter, so a UID with both a master AND per-instance
+    overrides yields multiple entries. This is what modern CalDAV
+    clients (Thunderbird 2024+, DAVx⁵, Apple Calendar) use for
+    initial sync and delta refresh.
+
+The suite exercises both paths — mixing them up is what tripped the
+first draft (calendar.event_by_uid → REPORT under the hood, returned
+the exception, tests failed).

+"""CalDAV REPORT method coverage via python-caldav.
+
+The REPORT verb (RFC 4791 §7) is how clients do bulk sync + filtered
+lookup. Three subtypes matter for OxiCloud's server surface:
+
+  * `calendar-query` (§7.8) — filter events by time-range /
+    property. `search(start=..., end=...)` in pycaldav emits this.
+  * `calendar-multiget` (§7.9) — batch fetch by href list. Used
+    when the client already knows which UIDs it wants.
+  * `sync-collection` (§7.9 / RFC 6578) — token-based delta sync.
+    Not exercised here yet — the server delegates to `list_events`
+    (no per-token filtering), so a coverage test would just
+    replicate the calendar-query case. Leave for later once real
+    sync-token support lands.
+
+The tests seed a fresh calendar with three timed events an hour
+apart, then exercise each REPORT shape. Row-count assertions are
+safe here because the seeded events are all masters (non-recurring),
+so master/exception folding doesn't apply — one URL per UID matches
+one row in DB.

+/**
+ * Dotfile-hide filter — end-to-end coverage of the UI-only, per-user
+ * `hide_dotfiles` preference (JSONB `auth.users.ui_preferences`).
+ *
+ * Deliberately narrow scope:
+ *
+ * 1. Toggle: a `.hidden` folder in `/files` disappears when the
+ *    toolbar eye button is pressed and reappears when it's pressed
+ *    again. This is the "does the filter actually filter" test.
+ *
+ * 2. Empty state: a folder that contains ONLY dotfiles renders the
+ *    "N hidden items — Show hidden files" affordance rather than the
+ *    generic "This folder is empty" copy. Clicking the affordance
+ *    flips the preference back off and the rows reappear. Guards
+ *    against a mystery-empty-folder regression.
+ *
+ * 3. Trash safety: the hide preference is deliberately IGNORED on
+ *    `/trash`, so a dotfile-named item still shows up for recovery.
+ *    Pins the "safety-net surface always shows everything" rule
+ *    against a future refactor that might extend the filter to
+ *    trash by accident.
+ *
+ * Other surfaces (favorites, recent, photos, public share) all
+ * derive from the same `filterDotfiles` helper and the same
+ * `preferences.hideDotfiles` reactive read; unit tests cover the
+ * predicate, so we don't burn browser cycles verifying each list
+ * page renders one more filtered row correctly. The three tests
+ * above hit the three DIFFERENT semantics (filter, empty-state,
+ * exemption), which is what actually needs regression coverage.
+ *
+ * Isolation. `hide_dotfiles` is per-user and persists on the server,
+ * so it survives the login-per-test that other specs rely on for
+ * isolation. `beforeEach` explicitly resets it to `false` and
+ * `afterEach` restores it, otherwise a failed test would leave the
+ * whole suite running with the filter on.

+// Fake OpenID Connect Identity Provider for the OxiCloud OIDC
+// integration test (tests/oidc/oidc.hurl).
+//
+// Wraps panva/node-oidc-provider — a spec-compliant OP — with a
+// minimal Node http front-end that auto-resolves every interaction
+// (login and consent) for a hard-coded test user. We don't wrap with
+// our own Koa instance because oidc-provider ships a bundled Koa that
+// the response prototype-checks against; layering another Koa around
+// it triggers `vary: res argument is required` on the first request.
+//
+// What we get from the library that we'd otherwise hand-roll:
+//   * Discovery (.well-known/openid-configuration)
+//   * JWKS endpoint + RS256-signed JWTs
+//   * PKCE S256 verification
+//   * Authorization code lifecycle
+//   * Refresh token + id_token + access_token shapes
+//
+// What we get FOR FREE when we later add coverage for:
+//   * Back-channel logout — flip features.backchannelLogout.enabled
+//   * RP-initiated logout — flip features.rpInitiatedLogout.enabled
+//   * Token revocation (RFC 7009) — flip features.revocation.enabled
+//   * Token introspection (RFC 7662) — flip features.introspection.enabled
+//
+// Each future OIDC feature is a config flag in this file rather than
+// new Rust protocol code to maintain.

+# OxiCloud — OIDC happy-path integration test
+# =============================================================
+# Drives the full SSO flow against the fake IdP under
+# tests/oidc/fake_idp/ (panva/node-oidc-provider with an auto-approve
+# interaction handler) and asserts every contract the SPA depends on.
+# Pinned regression: commit d1bbe8ba changed the callback's frontend
+# redirect from `/?oidc_code=…` to `/login?oidc_code=…` — Step 5's
+# `Location matches "^…/login\?oidc_code=…"` is the assertion that
+# would have caught that bug before users hit it.
+#
+# Flow walked manually (no auto-follow) so each handler is asserted
+# independently:
+#
+#   1. Bootstrap: create the local admin (provider list works
+#      regardless of admin presence, but the rest of the test
+#      lives more comfortably with a fully-initialised server).
+#   2. GET /api/auth/oidc/providers — SPA reads this to render
+#      the SSO button.
+#   3. GET /api/auth/oidc/authorize — server mints state + PKCE,
+#      redirects to the IdP.
+#   4. GET <IdP>/auth (+ full redirect chain) — fake-idp
+#      auto-approves login + consent, OxiCloud's callback
+#      JIT-provisions the user and redirects to
+#      {frontend_url}/login?oidc_code=… The final 404 (no SPA
+#      shell in test config) IS the test signal: we assert on
+#      the URL we landed at, which is the d1bbe8ba contract.
+#   5. POST /api/auth/oidc/exchange — SPA swaps the one-time
+#      code for tokens + cookies.
+#   6. GET /api/auth/me — proves the cookie session is live AND
+#      that every OIDC profile claim (name → username, given_name,
+#      family_name, picture → image, email, groups → admin role)
+#      was JIT-provisioned correctly into the local user record.
+#   7. POST /api/auth/refresh — rotation of all three cookies;
+#      proves the SPA's session-renewal path works on top of
+#      an OIDC-provisioned account.
+#   8. GET /api/auth/me — the refreshed cookies authenticate too.
+#   9. Existing-user re-login — a second OIDC flow with the same
+#      `sub` resolves to the same local user, not a duplicate.
+#  10. Anti-takeover — an unverified-email callback is rejected.
+#  11. POST /api/auth/oidc/exchange — replay-protection: the
+#      one-time code is single-use, second exchange returns 401.

+# Step 12 — Nextcloud Login Flow v2 via OIDC — MULTI-DRIVE PATH
+# ═════════════════════════════════════════════════════════════
+# Regression coverage for the customer-reported bug where OIDC
+# users were never shown the drive picker: the OIDC callback in
+# `auth_handler.rs::oidc_callback` used to mint the app password
+# inline and complete the flow with the bare username. Customers
+# with ≥ 2 drives had no way to pick a non-home drive under SSO,
+# and the deprecated `nc://` redirect broke NC clients that had
+# already picked up credentials via the poll backchannel
+# (`Impossible de valider la requête`).
+#
+# The fix routes the OIDC callback through the shared
+# `handle_oidc_login_completion` in `login_v2_handler.rs`, which
+# lists drives, renders the picker template on ≥ 2, and calls
+# `complete_flow(...)` only after the picker submit. Same
+# multi-drive fork the password path uses.
+#
+# What this section exercises (post-fix expected behaviour):
+#
+#   A. Local admin logs in with password to get a JWT for
+#      administrative operations (creating the shared drive
+#      below — the OIDC user has no local password).
+#   B. Admin creates a NEW shared drive owned by `oidc_user`. That
+#      makes the OIDC user's drive count = 2 (their JIT-provisioned
+#      personal + this shared), which is the multi-drive branch
+#      trigger.
+#   C. NC LFv2 initiate — anonymous, returns { poll_token, login_url }.
+#      login_url embeds the flow_token that identifies this flow.
+#   D. Pre-completion poll — MUST return 404. Baseline regression:
+#      if a future change ever accidentally auto-completes the flow
+#      before the picker submit, this catches it.
+#   E. Kick off the NC OIDC branch → GET /login/v2/flow/{token}/oidc.
+#      Server sets `nc_flow_token` on the OIDC state and 307s to
+#      the IdP.
+#   F. Follow the entire IdP → callback chain with `location: true`.
+#      Post-fix, the callback returns the PICKER HTML (200), NOT a
+#      `nc://` redirect. Pre-fix it would have 307'd to nc://.
+#   G. Poll AGAIN — still 404 (picker not yet submitted). Proves
+#      the callback did NOT call `login_flow.complete(...)` — the
+#      exact regression the fix prevents.
+#   H. Submit the picker with the shared-drive folder id.
+#   I. Post-picker poll — 200 with `loginName` matching
+#      `oidc_user~<uuid>` (composite marker → chroot-bound app
+#      password). This is the load-bearing assertion: pre-fix

+#            with `username/password`. Use JWT (Bearer) instead of

+# Why a separate runner from tests/api/run.sh:

+#
+# Invocation:
+#   * locally: chained from `just api-test` after the api + webdav
+#     suites, or directly via `bash tests/oidc/run.sh`
+#   * in CI:   chained from the `api-test` job in
