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

Thumbnails are now generated eagerly as lossy WebP (the primary codec) and
served to clients that advertise `Accept: image/webp`; JPEG is kept as a lazy
fallback for older clients and NextCloud, generated on first request and then
cached like WebP.
- ThumbnailFormat{Webp,Jpeg} enum threaded through encode/render/generate, the
on-disk path ({hash}.webp / {hash}.jpg), the moka cache key
(file_id, size, format), and cleanup (both formats removed).
- file_handler: parse Accept -> format, format-keyed ETag, `Vary: Accept` on
every response (incl. 304) so shared caches never serve the wrong codec;
Content-Type is byte-sniffed (infer) so it always matches the bytes.
- preview_handler (NextCloud) pins JPEG.
- webp = "0.3" (vendored libwebp via cc, no system dependency).
WEBP_QUALITY=82, chosen via a quality sweep (bench Table E1): SSIM within
~0.005 of JPEG q80 (imperceptible at thumbnail scale) for ~62% fewer bytes. On
the photo-realistic bench corpus the full set (3 sizes x 3 photos) drops 65.6%
(213->73 KB); real photos with edges/text land nearer ~25-40%. Encode is +5ms,
paid once in the eager background generator (off the request path).
The bench corpus is now photo-realistic (per-channel sums of low-frequency
sinusoids) instead of white noise, which had distorted codec byte ratios.
Methodology + numbers in benches/WEBP.md.

Thumbnails are now keyed by blob_hash on disk so identical files share
a single set of thumbnails (icon/preview/large). For 4000 duplicate
files with the same content, this reduces thumbnail storage from 12,000
files to just 3.
Changes:
- get_thumbnail_path() keys by blob_hash instead of file_id
- get_thumbnail(), get_cached_thumbnail(), generate_all_sizes_background()
accept blob_hash parameter for disk dedup
- generate_all_sizes_background() fast path: if blob-hash thumbnails
already exist on disk, skip image processing entirely and just
populate moka cache for the new file_id
- delete_thumbnails() only invalidates moka cache (shared disk
thumbnails must not be deleted when one file is removed)
- delete_blob_thumbnails() added for GC; garbage_collect() now cleans
up orphaned thumbnail files alongside blob files
- External thumbnails (video frames) stored as ext-{file_id}.jpg
since they are client-generated and not dedup-able
- ThumbnailPort trait updated with blob_hash parameters
- All handler call sites updated (file_handler, preview_handler)
- Tests updated for new signatures
Fix all clippy lints (collapsible if, clone on Copy, needless borrow,
redundant bindings, unused params) and apply rustfmt across the codebase.
Update test mocks to match Uuid-based trait signatures.

Backend:
- get_thumbnail: for non-images, serve cached thumb or 204 (not 400)
- store_external_thumbnail: validate + re-encode to WebP + persist
- get_cached_thumbnail: memory → disk lookup without generation
- PUT /api/files/{id}/thumbnail/{size} endpoint for client uploads
- ThumbnailPort trait: add get_cached_thumbnail + store_external_thumbnail
Frontend (photos.js):
- On <img> error for video tiles, use <video> + <canvas> to extract
a frame at 25% duration using browser's native codec
- Show frame immediately via blob URL
- Fire-and-forget PUT to server for permanent caching
- Subsequent visits serve cached WebP instantly (no re-extraction)
Zero server-side dependencies — CPU distributed across clients.
- JWT secret auto-generates and persists to <STORAGE_PATH>/.jwt_secret
- Remove setup token: first admin setup is open until system initialized
- Fix schema.sql: move CREATE EXTENSION pg_trgm/ltree to top
- Update login UI and auth.js to remove setup token fields
Remove async-trait dependency and use native Rust async fn in traits.
Replace Arc<dyn Trait> with Arc<ConcreteType> throughout the codebase
to enable monomorphization and eliminate dynamic dispatch overhead.
Key changes:
- Remove write-behind cache (no implementation existed)
- Fix should_transcode static method call
- Use ContactStorageAdapter directly instead of dyn AddressBookUseCase
- Clean up unused trait imports across services and DI

Standardize code formatting across all 173 Rust source files
using rustfmt. No functional changes - purely cosmetic.
This establishes a consistent code style baseline for the
project going forward.
