perf: round 12 — auth write-path narrowing, fused quota gate, moka blob-cache index, media single-read, sized listing JSON

Benchmark-gated round (benches/ROUND12.md; every change ships with a
BEFORE/AFTER harness + equivalence gates, one candidate rejected by its
own bench):

DB / query shapes (bench_round12_queries):
- NC sharee search: username-only projection instead of the 21-column row
  (incl. the <=512 KiB avatar) per match, + gin_trgm_ops indexes on
  auth.users for the leading-wildcard ILIKE (4.98x; 54.7x with index).
- Password login: delete the redundant full-row update_user — create_session
  already stamps last_login_at in its own txn (4.45x per login).
- Email-verified stamp: narrow conditional UPDATE (8.9x); OIDC repeat login
  now compares profile state in memory and issues ZERO queries when nothing
  changed (was: full 17-column rewrite per login).
- Refresh rotation: revoke+insert+stamp fused into one transaction via new
  rotate_session port method (1.18x).
- WOPI CheckFileInfo / authorize_wopi_access: require(Read) + get_file +
  check(Update) overlapped with tokio::join!, original result precedence
  (cold 1.34x).
- Upload quota gate: user-envelope + drive-cap checks fused into ONE
  round-trip (check_upload_quotas) — the NC chunked PUT pays this per
  chunk (1.81x, 2 -> 1 queries/chunk); shared verdict evaluators keep
  error shapes byte-identical.

CPU / allocs (bench_round12_micro):
- sized_json: pre-sized listing serialization replacing axum Json's 128 B
  seed + doubling-realloc chain on files/folder-resources/photos/search
  responses (1.40x, 13 -> 2 allocs per 500-row page; byte-identical).
- Security headers: 4 SetResponseHeaderLayer folded into the CSP middleware
  pass (5 layers -> 1; 1.43x per request, -26 allocs; header set gated
  byte-identical incl. 304s).
- Media capture-metadata: single-read extraction — nom-exif now parses the
  buffer kamadak already read (zero-copy Bytes) and videos open once with a
  kind() dispatch; per-image opens 2-3 -> 1 (1.44x warm geomean, 1.6-3.2x
  cold cache; extraction outputs gated identical incl. the MIME-mislabel
  track fallback).
- Chunked-upload session ops: owner gate folded into the operation's own
  DashMap lookup + stack-encoded uuid compare (5 -> 3 lookups, -2 allocs,
  1.28x per chunk).

Blob cache (bench_blob_cache_index + round-3 regression guard):
- CachedBlobBackend index: tokio::sync::Mutex<LruCache> -> moka::sync::Cache
  with byte weigher. The mutex serialized every cached chunk read and scaled
  NEGATIVELY (2.08 -> 1.07 Mops/s from 1 -> 2 readers); moka probes are
  lock-free (2.17x at K=2). Byte budget now enforced by moka (manual
  current_size + collect_evictions machinery deleted); eviction listener
  unlinks size-evicted files only (Replaced entries keep their file —
  gated). Single-flight miss gate unchanged (16 concurrent misses -> 1
  fetch re-verified via the round-3 harness).
- put_blob now populates the cache BEFORE the inner backend consumes the
  source file (the old order failed 100% of the time — local renames,
  S3/Azure delete the source — so the first read after a whole-file put
  re-downloaded from the remote); inner-put failure invalidates the entry.

Frontend (vitest gates):
- List-view thumbnails request the 150px icon rendition instead of 400px
  preview into a 40px slot (~7.1x fewer pixels, ~4-5x fewer bytes per
  thumbnail across list views); grid keeps preview.

Rejected by its own bench (kept as evidence in bench_round12_micro §2):
- Single-pass compression predicate: the monomorphized And-chain already
  costs ~4.6 ns / 0 allocs total; the fused node measured within noise.

New migration: 20260719000000_users_search_trgm.sql (trgm indexes).
Deferred with prepared design: grouped file/grid view virtualization
(single-VirtualRows flatten, the photos pattern) — next round's headline.

# Round 12 — auth write-path narrowing, fused quota gate, moka blob-cache index, media single-read, sized listing JSON
Benchmark-gated, same rule as ROUND2-11: 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. 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.
Measured on 4 cores / 15 GiB, local PostgreSQL 16 (fsync off), release
profile; frontend on Node 22 / vitest 4. Reproduce any row with the command
in its section.

## [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`.

//! ~1.3× the payload on every hot listing response (files, folder

//! (benches/ROUND12.md §M1, 1.40x / −11 allocs on a 500-row page).
//!
//! The per-row estimates are calibrated against the serialized DTOs (a

//! doubling — still far better than the 128-byte seed; overestimates waste
//! transient capacity only (the buffer is freed after the response).
