Two items from the ROUND17 deferred list, each benchmark-gated with a
BEFORE/AFTER equivalence gate and a rollback-on-regression check (ROUND2–17
discipline). See benches/ROUND18.md.
[C1] backend — 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. calendar_storage_adapter::update_event
fans a multi-field edit out into one call per changed field, so a full REST
edit paid one full-body (up to ~11 KB) allocation per property. The body is
now mutated in place (replace_range for an existing property, four insert/
insert_str for a new one, byte-identical spans) and the single "\nNAME:"
needle is built on the stack (the "\r\nNAME:" needle was redundant — the LF
form is its suffix). bench_round18_micro [C1]: 70 -> 2 allocs/op (68 fewer),
2.46x wall, emitted body byte-identical.
[F1] frontend — ResourceList itemIndexById rebuilt a fresh Map over the whole
accumulated list every infinite-scroll page (O(N)/page, O(N^2) drain) and,
being a new instance each page, re-fired the reap-stale effect (another O(N)
id Set/page). New ItemIndexBuilder extends a persistent Map with the fresh
page only and reuses the reference across appends; the reap-stale effect now
tests membership against it. round18.bench.test.ts [F1]: 40x50 drain 74.1 ->
6.4 ms (11.5x), deep-equal to the reference at every page, reference-contract
gate (same-ref append / new-ref rebuild).

Benchmark-gated, same rule as rounds 2–14: every change ships with a
BEFORE/AFTER benchmark and an equivalence/safety gate; an AFTER that doesn't
beat its BEFORE is rolled back. The rule is encoded per harness (GATE FAIL
non-zero exit in the Rust examples, threshold expect() in vitest).
F1 — Grouped listings (trash / recent / favorites / shared-with-me)
re-bucketed the WHOLE accumulated list on every infinite-scroll page.
ResourceSectionsBuilder (new, off the reactive graph) re-buckets only the
fresh page and hands VirtualList the same rows array reference for untouched
buckets. 50×50 (2 500-item) drain: 63 750 → 2 500 bucketOf calls (25.5×),
12.5 → 1.3 ms wall (9.9×); O(N²/page) → O(N). Deep-equal to the full-rebuild
reference at every page for both a contiguous (date) and a non-contiguous
(trash-by-drive) group-by; reference-stability + fallback gated.
B1 — exif Make/Model: the display String was thrown away to allocate the
trimmed copy; display_value_trimmed trims in place (drain + truncate), 2 → 1
alloc per field (8 → 4 allocs/op, 1.26×).
B2 — content-index worker: text_extractor::supports (lowercases MIME +
extension) was called twice per file per drain batch; classify once into a
Vec<bool> and thread it through both uses. 256-file batch: 704 → 353 allocs,
34.5 → 16.7 µs (2.07×).
B3 — tantivy: skip SnippetGenerator::create on a zero-hit content search
(return Ok(vec![]) once top_docs.is_empty()); the per-hit loop was empty.
400-doc index: 1 575.6 → 1 237.2 ns (1.27×), widens with index size.
Harnesses: examples/bench_round15_micro.rs, examples/bench_round15_tantivy.rs,
frontend resourceSections.bench.test.ts; writeup in benches/ROUND15.md. Also
normalizes two round14 bench examples that were committed unformatted
(cargo fmt --all).

Benchmark-gated (benches/ROUND14.md); every change ships a BEFORE/AFTER
benchmark with an equivalence gate and is rolled back on regression (the
rule is encoded as a GATE FAIL exit / threshold expect).
Backend
- Q1 faces_for_file → narrow face_boxes_for_file(id, person_id, bbox) with the
caller filter pushed into SQL: drops the 2 KiB embedding BYTEA + 6 unused
columns per face. 15-face lightbox open 0.312→0.219 ms, 32 KB→840 B/req.
- A1 cookie auth uses the borrow-only extract_cookie_str (already backs CSRF)
instead of extract_cookie_value's owned String: -1 alloc/cookie request.
- A2 compute_relevance ASCII case-fold fast path vs name.to_lowercase() per
result row (Unicode fallback preserved): 1.40x, 12→3 allocs/page.
- A3 sub pre-parsed to Uuid at decode time (TokenClaims.sub_id) vs re-parsing
the 36-char claim on every request incl. cache hits: 22.7→0.7 ns.
- A4 auth + NextCloud middlewares borrow request.headers() instead of taking
axum's HeaderMap extractor (a full map clone): 2→0 allocs/authed request.
- A5 CalDAV getlastmodified via the stack rfc2822_utc (byte-identical to
chrono) vs a per-event to_rfc2822() heap String: 5→0 allocs.
- A6 CalDAV per-event href + quoted etag written into reused page buffers vs a
fresh format! pair per event: 3.48x, 240→6 allocs/40-event page.
Frontend
- F1 t() shares one frozen EMPTY_PARAMS for the no-interpolation call forms vs
a throwaway {} per call: -1 alloc/call.
- F2 favorites favoriteIds is a persistent SvelteSet with per-page add (clear
on reset) vs a brand-new set over the whole accumulated list each page:
22.3x over a 40-page drain (O(N^2)→O(N)).
Verified: cargo check --all-targets, cargo clippy -D warnings, both bench
packs (GATE PASS), frontend npm run check + vitest (4/4). ROUND14.md also
records the investigated-but-deferred backlog (music N+1, contact vcard
over-fetch, CachedBlobBackend syscalls, ResourceList.sections builder, etc.).

Benchmark-gated (BEFORE/AFTER + equivalence/safety gate per change), same
discipline as rounds 2-12. Full write-up in benches/ROUND13.md.
Shipped:
- V1 Grouped views windowed (files route + ResourceList). The grid arm was
the last unwindowed path (trash is grouped-by-default in grid): each
swimlane now feeds its own VirtualList, outer container a flex stack.
vitest gate: 800-item grouped grid mounts <120 .file-item (was 800).
- Q1 get_users_by_ids drops the <=512 KiB avatar image + ui_preferences
JSONB (notification path never reads them). 30-member fan-out 8.60 ->
0.25 ms (34.3x), ~7.7 MB off the wire.
- Q2 Login provisioning is_empty() -> SELECT EXISTS for calendar + address
book (every login). 0.193 -> 0.170 ms, widens with owned-row count.
- Q3 Recent-access prunes only when the upsert inserted (RETURNING xmax=0)
— a re-access can't grow the set. 0.567 -> 0.324 ms (1.75x).
- L1 Locale supported-codes precomputed once vs rebuilt per anonymous
request. 616 -> 17.3 ns (35.7x), 18 -> 1 allocs.
- H1 Duplicate /api TraceLayer removed (global stack already wraps it).
1.86 -> 1.42 us/request, -6 allocs.
- H2 client_ip span field: borrow-only ClientIpDisplay vs owned String.
187 -> 173 ns, -1 alloc.
Not shipped (discipline): the "media hooks read the blob 3x" lead was a
correctness bug, not a perf dup — the raw-path metadata/faces readers
resolve only for local+unencrypted+single-chunk blobs and silently produce
nothing otherwise. Flagged for maintainers; routing through read_blob_bytes
is a correctness fix (perf-neutral-to-negative), not a benchmark-gated
perf change.

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.

Conflict resolution re-applies the round-11 SPA optimizations onto the
refactored item-based ResourceList (which independently converged on the
favoriteIds-prop star — S2 is now upstream's shape):
- ResourceList.selectedItems: upstream reintroduced the full O(N)
items.filter per selection toggle; replaced with the round-11
id-index projection — O(k·log k), item order preserved
(benches/ROUND11.md §S1)
- favorites/recent pages: upstream's rewrite kept the host-side
selectedItems shadow + unused selectedIds mirror and ignored the
batchToolbar snippet param; re-applied the param-consuming shape and
deleted the shadows
Validation on the merged tree: clippy --all-features --all-targets
-D warnings clean; cargo test --workspace 524 passed; frontend npm run
check 0 errors; vitest 310 passed (upstream's new tests + round-11 gates)

Backend (each change benchmark-gated with BEFORE replicas + equivalence
gates; see examples/bench_round11_micro.rs, bench_round11_queries.rs,
bench_log_writer.rs and benches/ROUND11.md — final numbers land in the
follow-up doc commit):
- StoragePath re-representation: single canonical joined String, segments
derived on demand; File/Folder drop the duplicated path_string field
(4000→1000 allocs per 500-row listing page)
- Display classifier fusion: classify_display shares one stack-lowered
extension across the three decision trees; call sites in FileDto,
folder/favorites/recent handlers, trash, path-resolver (+ interning
where Arc::from was still used)
- /status.php and /openapi.json memoized into OnceLock<Bytes> (openapi
rebuilt a 171 KiB spec per request: 2.8 ms → 18 ns)
- NC upload-session PROPFIND: write! + pre-sized body + stack RFC2822
dates (2.3-2.6x, 2582→772 allocs at 256 chunks)
- REST download: dead FileDto clone removed (capture mime/size + move)
- CalendarEventDto/TrashedItem into_parts moves (11 KiB ical_data memcpy
gone per CalDAV row); CardDAV getlastmodified stack render
- 4xx path: borrowed ErrorResponse serialize, ErrorKind::as_str,
not_found/already_exists clone kill
- vCard emit via write!; search page moved out with into_iter skip/take;
content-hit UUIDs parsed once; group last-user check via HashSet
- RateLimiter: lock-free get + insert (and_upsert_with variant REJECTED
by benchmark); CSRF token borrow-compare + borrowed cookie extraction
- Thumbnail/preview ETags built from as_str (Debug-identical bytes)
- Encrypted backend: encrypt_in_place_detached single-buffer write path,
chunk-sized reserve in collect_stream; retry labels made lazy
- PG: deferred upload registration 3→1 round-trips (persist_file CTE
template); direct_grant_cache for Calendar/AddressBook/Playlist authz
(single-flight + set_role/clear_role invalidation); expand_user
tokio::join!; geo clusters min(uuid)::text; recluster face assignment
batched into one UNNEST update
- People recluster cosine: norms precomputed once (bit-identical gate)
- NC capabilities poll logs demoted to debug; tracing-appender dep added
for the log-writer benchmark
Frontend:
- ResourceList.selectedEntries O(N)-per-toggle → id-index projection
O(k log k); favorites/recent consume the batchToolbar snippet param and
drop their duplicate filter + dead selectedIds mirror
- Recent: star state via new favoriteIds prop — a star click no longer
rebuilds all N entries
- admin timeAgo >30d fallback uses the cached Intl.DateTimeFormat
- vitest gates in src/lib/components/round11.bench.test.ts

Round 3 of benchmark-gated optimizations (benches/ROUND3.md; every change
gated by a before/after benchmark — an AFTER that did not beat its BEFORE
was to be rolled back; none needed it. Equivalence gates assert identical
row sequences / byte-identical output on every behavior-preserving rewrite):
DB hot paths (local PG16, EXPLAIN-verified):
- Web-UI listing (list_resources_paged): cursor pushed INSIDE the
folders/files UNION-ALL branches as sargable row-value comparisons with
per-branch ORDER/LIMIT + two partial expression indexes
(folder_id, LOWER(name), id). 20k-entry folder: 26.6 -> 1.3 ms/page
(19.5x); other sort modes at parity or better. New migration
20260918000000. [benches/LISTING-KEYSET.md section in ROUND3]
- Photos timeline (list_media_files): per-drive CROSS JOIN LATERAL top-N
on the timeline index, joins moved above the top-N. 50k-photo library:
97.4 -> 1.6 ms/page (55.7x). The old "LIMIT stops the scan early"
comment was refuted by EXPLAIN.
- PROPFIND sub-folders (both DAV surfaces): keyset list_folders_batch off
idx_folders_unique_name replaces COUNT(*) OVER() + LIMIT/OFFSET
(5k dirs: 79.7 -> 17.9 ms full walk, 4.5x).
Concurrency:
- Basic-auth cache single-flight (moka try_get_with): 8 concurrent DAV
connections at TTL expiry paid 8 Argon2id runs (2.6 s CPU + 8x64 MiB);
now 1 (300 ms). Failed verifications remain uncached.
- CachedBlobBackend per-hash single-flight + unique tmp names: 16
concurrent cold readers = 16 full remote downloads racing truncating
writes on ONE deterministic .tmp (corruptible cache); now 1 download
(16x less egress, 2.8x wall on a shared link) and torn files can never
be renamed into the cache.
I/O and allocations:
- Chunk-assembly reads 64K -> 512K buffers (2.3x, 8x fewer syscalls);
chunk-spool writes via BufWriter 512K (5.6x, 32x fewer syscalls).
- S3/Azure put_blob_from_bytes_unsynced overrides: dedup settle no longer
pays a HEAD probe per new chunk (2 RTT -> 1, 1.8x); Azure stops copying
every chunk (Bytes -> Body, -0.44 ms - 4 MiB alloc per 4 MiB chunk).
- Entity->DTO mapping: Arc<str> interning of closed-set display fields +
common MIMEs, 1-alloc etag/size formatting, FolderDto moves instead of
clones. File row: 11 -> 4 allocs; folder row: 11.8 -> 1 (2.1x faster).
- CardDAV REPORT: deleted dead per-contact vCard pre-generation and the
O(N^2) uid scan whose result was discarded (5k contacts: 55.7 -> 5.7 ms,
9.8x); byte-identical XML asserted.
- Search-results cache: byte weigher + 32 MiB budget
(OXICLOUD_SEARCH_CACHE_MAX_BYTES) replaces the 1000-ENTRY cap that let
~300 MiB of enriched rows sit in RSS; read latency parity.
- Dropped aws-config + aws-smithy-types (zero references; -82 dep-graph
nodes, three SDK stacks gone from every build). tokio "process" is now
an explicit feature (was enabled transitively by aws-config).
Frontend:
- Cached Intl.DateTimeFormat keyed by (locale, options) in formatDate and
4 sibling callsites: 20k dates 2612 -> 51 ms (51.6x); vitest gate
asserts output identity across locales and a 3x floor.
Validation: cargo fmt + clippy --all-features --all-targets -D warnings
clean; 518 unit + 548 integration-cfg tests green; new-shape endpoints
smoke-tested end-to-end over HTTP (all 5 listing sort modes with cursor
walks, WebDAV PROPFIND Depth-1, photos timeline, Basic-auth DAV login);
frontend npm run check clean, new vitest gates green.

- add resource kind filter (file, folder, drive) in shared section (localStorage stored)
- add user preferences serverside store
- add client side dotfile filter (show/hide dotfiles) (user perf stored, default: dotfiles are shown)
for security trashed dotfile are always displayed
protection added: if a folder has only hidden items, a notification invite user to display it
if a user rename or create a hidden item, a notification tells it to user
Add an end-to-end and unit test suite for the SvelteKit frontend:
- Playwright e2e specs (tests/e2e/spa) with a throwaway container stack,
codegen scenarios, and an Istanbul-based coverage report pipeline.
- Vitest unit tests across API endpoints, components, stores and composables.
- `data-testid` hooks on interactive elements (AppShell, FileViewer,
ShareDialog, search, photos, files breadcrumbs, login/Nextcloud flows,
public share pages) so the e2e suite can target them deterministically.
- Serve the SPA app-shell CSP from a <meta> policy (svelte.config.js) plus a
middleware that skips the CSP header on HTML; move the Nextcloud Login Flow
v2 grant page to the SvelteKit /nextcloud/login route.
- `just front-codegen` recipe and start-server-spa.sh harness.
Make the test environment robust and consistent:
- Install a deterministic in-memory localStorage/sessionStorage in the Vitest
setup so storage behaves identically across Node versions (Node 26 ships a
native Web Storage global that otherwise shadows jsdom's).
- Pin devenv to Node 26 + PostgreSQL 18 and pin every CI job to Node 26.3.0
so the dev shell and CI run the same toolchain versions.
Repair the API/WebDAV (hurl) suite, which had drifted from the backend:
- Migrate the removed `/api/folders/{id}/listing` endpoint to `/resources`
(cursor-paginated `{items:[{resource_type,resource}]}` shape) across the
batch-copy, grants, nested-group, and WebDAV NC tests + the dav_helpers
wipe routine.
- Stop photos_etag from uploading the dedup-tracked fixture so the dedup
blob-lifecycle test can own its content-addressed blob exclusively.
- dedup_create now asserts the idempotent same-content re-upload (201 +
existing file id) instead of the stale 409 expectation.
Generated coverage reports, nyc output and the e2e server runtime data dir
are gitignored rather than committed.
Checkpoint of the in-progress frontend toolchain work (Vite pinned to ^6 after
the 7/8 rolldown build break, eslint-plugin-svelte v3 navigation/reactivity
fixes, CI/Dockerfile/manifest updates) together with three UI performance
optimizations (verified on the Vite 6 build):
- Critical CSS: move auth.css/music.css off the global path into their route
chunks (login/device/nextcloud-login, music) -- -25% gzipped critical CSS
(~5.4 KB) on every non-auth/non-music page load.
- relativeTimeAgo: cache the Intl.RelativeTimeFormat (was rebuilt per call, once
per row per render) -- 22.7x faster date formatting in large lists.
- Virtualize search results and grouped trash (list view) via VirtualList -- DOM
rows mounted stay ~constant (~27) instead of O(N) (94.6% fewer for 500 hits).

Bundles the backend+frontend delta-upload (content-dedup) feature with a
batch of frontend fixes from this session.
Upload / dedup:
- Client-hashed delta & instant upload (deltaUpload, hashWasm vendor shim)
- Backend dedup batch endpoint (dedup_service, dedup_handler, routes)
- session store owned-hash helpers; unit tests + upload-strategy bench
Frontend UI/UX:
- Colour file-type icons in grid/list (per-type tinted tiles + glyph hue)
- Robust thumbnail fallback; PDFs now show their type icon (backend
generates no PDF thumbnails) instead of a blank tile
- Fix PDF preview: load via a same-origin blob: iframe — the API URL is
blocked by the global X-Frame-Options: DENY in the browser's framed
PDF viewer, matching the existing CSP `frame-src blob:` design
- Groups: localized virtual-group description (no DB schema-note leak),
add nav.groups to the 15 missing locales, fix primary-button contrast
- Repoint --color-text-light → --color-on-accent (was faint grey on accent)
- Nudge the admin role badge off the user-menu header divider

Backend — tail latency & throughput:
- FileContentCache, image transcode, and search now use moka single-flight
(try_get_with / get_or_load) so N concurrent misses for the same key
collapse to one disk read / transcode / query instead of a thundering herd.
Microbenchmark (128 concurrent on one hot key): 128 loads / p99 ~1023ms
before vs 1 load / p99 ~32ms after.
- DB: configurable per-statement timeout on the primary pool
(OXICLOUD_DB_STATEMENT_TIMEOUT_SECS, default 30; maintenance pool exempt) so
a runaway query can't pin a connection and starve the pool.
- DB: background pool-saturation monitor
(OXICLOUD_DB_POOL_MONITOR_INTERVAL_SECS) that WARNs as the primary pool nears
exhaustion — the early signal before tail latency cliffs.
- mimalloc: set MIMALLOC_PURGE_DELAY=0 (Dockerfile + compose) so freed pages
return to the OS and RSS tracks the live working set; benchmarked on
musl/aarch64 at ~400MB reclaimed vs 0MB with the default.
Frontend — UI / i18n fixes:
- i18n: fix literal "{{count}}" and "{{percentage}}/{{used}}/{{total}}" in the
selection toolbar and storage line — the call sites passed param names that
didn't match the locale placeholders; unify on `count` and pass the storage
template its params. Add es files.selected_count.
- sidebar: hide the drive picker when there's only one drive (the redundant
"Personal" row); remove the coloured left accent on the active nav item.
- logo: stop clipping the cloud's left bulge — viewBox recentred on the cloud's
true bbox with proportional SVG size so it keeps the same rendered scale.
- user menu: drop the default <a> underline on the link rows.

Defer loading components that are off the initial render path until they
are first needed, keeping them out of the bundle that loads on page entry.
- Add `lazyComponent` composable: a tiny rune-based holder that dynamic-
imports a component on first `load()` and exposes it for `{@const}`
rendering, with the component type inferred from the module so prop/
binding type-checking stays intact.
- CommandPalette: loaded on the first Cmd/Ctrl+K and mounted open via a
new `autoOpen` prop. It was previously imported by AppShell, i.e. in the
initial chunk of every authenticated route (~27 KB). AppShell now owns
the shortcut that triggers the load.
- FileViewer + WopiEditor: loaded when a preview/editor first opens, across
files, recent, favorites and shared-with-me.
- PhotoLightbox / PlacesMap / PeopleView: loaded on first lightbox open or
when the places/people tab is selected (the latter also defers maplibre).
Once loaded a component stays mounted and behaves exactly as before, so
behavior is unchanged on the second use onward.
- About modal overlay used a raw z-index: 1200, below the semantic
--z-modal (3000)/--z-toast (4000) layers, so token-based surfaces would
cover it. Consume var(--z-modal) instead.
- .btn-primary and .search-button sit on the accent gradient but coloured
their text with --color-danger-text (only correct by coincidence, #fff).
Use the purpose-built --color-on-accent so retinting danger can't break
them. The other --color-danger-text uses are white-on-red and stay.
- --color-item-hover-blue/--color-item-hover-sky were light-only literals
that would read wrong in dark mode; wrap them in light-dark().

The per-section icon colours used :nth-child(1..6), but the nav grew to 8
items (files, shared, shared-with-me, recent, favorites, photos, music,
trash). The colours had drifted out of sync with their labels, and music
and trash got no colour at all.
Map each item's colour off a stable `data-section` key instead, covering
all eight sections with distinct curated calendar-dot hues (sibling blues
for the two share directions, purple for music, red for trash). Reordering
or adding nav items can no longer desync the colours.

Two related parity gaps from the VanillaJS → Svelte migration (issue #500):
internal-vs-external users weren't badged, and external users in a share's
member list rendered as a bare UUID with a static icon — no avatar, no email.
Both share one root cause: there was no shared user vignette and no resolver
for non-directory (external) users (the system address book lists internal
users only, and ShareDialog hardcoded isExternal=false).
- lib/api/endpoints/users.ts: resolveUser(id) — cached GET /api/users/{id}
(the authenticated per-user profile lookup) → {name, email, image,
isExternal}; returns null when the profile isn't visible so callers keep
their fallback label.
- lib/components/UserVignette.svelte: reusable identity chip — avatar (photo
or coloured initials), name, email, and a building-circle-xmark badge for
external users; resolves lazily and falls back to a caller-supplied label.
- lib/utils/avatar.ts: userInitials() + avatarColorIndex() extracted from
AppShell (now shared by both — no duplicated logic) so vignette and account
button render identically.
- ShareDialog: user member rows now render <UserVignette>; groups keep their
icon+label. Drops the dead hardcoded isExternal.
Backend already exposes everything (UserDto.email/image/is_external via
GET /api/users/{id}); no backend change. Frontend gate green (svelte-check
0/0, eslint, stylelint, prettier) + 47 Vitest.

Places fell back to a flat themed background (blankStyle) when no Protomaps
.pmtiles basemap was present, so the map was just a grey void behind the
photo markers.
Replace that with worldStyle(): a MapLibre GL v8 style that draws land masses
and country borders over a themed ocean, sourced from a bundled Natural Earth
110m outline (public domain). The asset is geometry-only (properties stripped,
coords rounded to 2 decimals) — 177 features (148 Polygon + 29 MultiPolygon),
~165 KB — served same-origin at /geo/world-110m.geojson, so no external tiles
(CSP connect-src 'self' friendly) and no per-instance basemap install. A full
Protomaps basemap still takes precedence when one is installed.
Also add a quiet map 'error' handler: if the outline is ever missing, the SPA
fallback serves index.html (text/html) which MapLibre can't parse as GeoJSON;
markers still render over the ocean layer, so swallow the error rather than
logging to the console (mirrors the checkBasemap content-type guard).

Two issues kept the Photos → Places map blank once the SPA could boot:
- CSP `worker-src 'self'` blocked MapLibre GL, which spawns its web worker
from a blob: URL, so the map never constructed. Allow `worker-src
'self' blob:` ('self' still covers same-origin workers like delta-upload).
- `checkBasemap()` trusted `res.ok`, but the SPA fallback serves index.html
(HTTP 200, text/html) for any missing path — so a missing basemap.pmtiles
read as "present", and pmtiles.js then choked on HTML ("Wrong magic
number for PMTiles archive"). Reject text/html responses so an absent
basemap falls back cleanly to the themed blank style.

The files browser re-fetched the first 200 favorites AND the first 200 outgoing
shares on every folder navigation (two round-trips each time) just to render the
star / shared badges — work that grew with how much the user browsed, for data
that barely changes.
Move both id sets into a session-scoped `badges` store: `ensureLoaded()` fetches
once (concurrent callers share one in-flight request) and every later navigation
reads from cache, so browsing costs zero extra requests. Mutations keep the cache
in sync optimistically:
- favorite toggle / batch-favorite → `setFavorite` (revert on failure),
- share creation → `markShared`, wired through a new optional `onshared` callback
on ShareDialog (fired when a grant or public link is created). This also makes
the shared badge appear immediately instead of only after re-navigating.
Net effect per session: badge fetches drop from O(navigations) × 2 to 2 total.
The 200-item ceiling is unchanged from before; the fully-correct fix is per-item
flags on the listing endpoint (a backend change, noted in the store).
Verified: new badges store unit tests (load-once, concurrent de-dupe, optimistic
favorite/share, reset) and a headless render of the real files route in list and
grid (virtualization intact, no runtime errors).

Extends windowing to the remaining O(n)-DOM surfaces: the card-grid view of
ResourceList (recent / favorites / shared / shared-with-me / trash / search) and
the main file browser (`files/[...path]`), in both list and grid layouts.
- VirtualList gains a real grid mode: its inner window carries the caller's grid
class (`files-grid-view`) and lays out `columns` cards per windowed row. The
row pitch is auto-measured (grid card height tracks column width via the 4/3
aspect-ratio thumbnail) and re-measured on resize.
- `useVirtualWindow` now distinguishes scroll from resize and exposes a
`resizeTick`, so size-dependent layout (the grid pitch) is recomputed only when
it can actually change.
- `gridColumns(width)` (new util) mirrors the CSS `auto-fill` / `--grid-card-min`
/ gap so the windowed row count matches the browser's real wrapping exactly;
shared by both grid callers.
- The files browser flattens folders-then-files into one discriminated `entries`
list rendered through VirtualList (list: columns=1; grid: columns from width).
Grouped (swimlane) views stay fully rendered, as before — they're bounded.
ResourceList GRID, headless Chromium (1280x900), synthetic rows, before/after:
rows | mount→paint | DOM nodes | JS heap | scroll frame | jank frames
------+-------------+-----------+---------+--------------+------------
1000 | 979→75 ms | 19k→879 | 16→3 MB | 16→17 ms | 0→0
5000 | 4005→67 ms | 95k→879 | 72→3 MB | 37→17 ms | 26→0
20000 |12015→65 ms | 380k→879 |281→7 MB |197→17 ms |1249→19
Rendered DOM and heap are flat (O(visible)) regardless of dataset size; mount is
~185x faster and scroll holds ~60fps. Verified visually mid-scroll (5 columns,
4/3 thumbnail tiles, cards land at the expected indices). The files browser
shares the same VirtualList path (it can't be mounted headless — it depends on
$app routing/session — so it's validated via svelte-check + the production build
+ the shared, separately-benchmarked component).
