Backend — Photos timeline now groups by real capture date instead of upload time. New MediaMetadataService (FileLifecycleHook) extracts EXIF DateTimeOriginal from images and container creation_time from videos (mov/mp4/mkv) via nom-exif, timezone-correct (OffsetTimeOriginal), persisting captured_at so the existing media_sort_date trigger takes over. Adds POST /admin/photos/metadata/reextract to backfill existing media. Falls back to upload date when no embedded date exists.
Frontend — premium grid cards: combined metadata line (relative date · size, owner avatar when shared), custom selection checkbox with a clear checked state, uniform full-width 4:3 thumbnail tiles independent of filename length, centered file-type icons, and a hit-test fix so checkbox/star/kebab clicks reach the controls (the decorative thumbnail no longer captures pointer events). Notification messages internationalised across all 16 locales. Broader polish: design tokens, a11y/focus-visible states, brand + PWA assets.
Chore — bump semver-compatible dependencies (cargo upgrade); add nom-exif 3.6.1.

Phase 2 — the client side of "upload only what changed", closing the
delta-sync plan.
WASM (wasm/oxicloud-hash): DeltaChunker adds incremental FastCDC with
the server's exact crate and parameters (64K/256K/1M) next to the BLAKE3
hasher. The incremental split is provably identical to a single pass:
every chunk except the last ends on a content/max-size condition whose
decision window was fully buffered, so only the tail is provisional and
re-examined as slices arrive. A mirror test — the client twin of the
server's stream≡slice test — chunks 4 MiB of xorshift noise with
adversarial slice sizes (7 B … 8 MiB) and requires boundary-for-boundary
equality with one FastCDC pass. Vendored artifacts rebuilt (55 KB wasm).
Worker (static/js/workers/deltaWorker.js): the full protocol off the
main thread with OVERLAPPED stages — 8 MiB file slices feed the chunker
while earlier batches (256 hashes) negotiate and their missing chunks
upload through a 2-deep PUT pool (≤8 MiB framed bodies, bytes re-sliced
from the File at send time, never hoarded). Commit handles 409
still_missing by uploading exactly the named hashes and retrying.
Orchestrator (features/files/deltaUpload.js): threshold (8 MiB),
worker lifecycle + size-scaled timeout, progress relay to the upload
bell, conclusive-outcome mapping (201/200, 507 quota, 409 name
conflict) and silent fallback to the byte upload for everything else.
Wired into uploadFiles and uploadFolderEntries, which now surface one
batch summary of the bytes dedup saved. This subsumes the whole-file
instant-upload module — a fully-known file negotiates to nothing
missing and the commit short-circuits on possession — so
instantUpload.js and hashWorker.js are removed (the /api/dedup/check
and /api/files/by-hash endpoints remain for API clients).
Verified end-to-end against PostgreSQL 16 — the cross-boundary proof
the whole design hangs on, in both directions: a 24 MB file byte-
uploaded (server-side CDC) then edited and delta-negotiated with
WASM-computed chunks reported missing 1/74 (boundaries bit-identical),
synced with 344 KB on the wire vs 24 MB (98.6% saved) and downloaded
byte-identical; inversely, a file created via delta then byte-uploaded
as identical content produced a server-side manifest DEDUP HIT with the
same content_hash. Insertion at the head of the file (the adversarial
CDC case) still negotiated missing 1/74. Chunk+hash throughput ≈275 MB/s
in V8 with SIMD128.

Phase 0 of the delta-sync plan. Re-uploading a file the user already has
(another device, a restore, a duplicate) used to transfer every byte just
for the server to discard them as a dedup hit. The frontend now computes
the file's BLAKE3 locally and, on a hit, registers the file with a single
~150-byte metadata call.
Server — POST /api/files/by-hash:
- All checks live in the application service per the AuthZ rule:
Create permission on the target folder via the authorization engine,
hash ownership via the existing user-scoped query (a non-owned hash
returns 404 — same shape as "no such blob" — and emits an
instant_upload.rejected audit event), quota on the logical size.
- On success: one ref_count bump + the existing save_file_with_blob row
registration (compensation included); is_new_blob=false so lifecycle
hooks skip thumbnail regeneration. ~10 ms warm.
- The storage-usage service is now built before the application services
and injected, instead of only living on AppState.
Client — WASM BLAKE3 + worker:
- wasm/oxicloud-hash: the exact same blake3 crate the server uses,
compiled with WASM SIMD128 (~660 MB/s measured) so browser hashes match
server content addresses bit for bit. Built by scripts/build-wasm.sh;
the artifacts (45 KB wasm + 8 KB glue) are vendored like pdf.js — no
npm dependencies, no wasm toolchain needed for regular builds.
- static/js/workers/hashWorker.js streams the File in 8 MiB slices off
the main thread (constant RAM at any file size).
- features/files/instantUpload.js orchestrates: threshold (8 MiB — below
it the round-trips cost more than the bytes), user-scoped
/api/dedup/check, by-hash registration, and silent fallback to the
normal byte upload on any miss, race or unsupported environment.
Wired into both uploadFiles and uploadFolderEntries.
- biome.json vendors exclusion fixed to cover nested directories
(previous vendors were .mjs and never matched the *.js include).
Verified end-to-end against PostgreSQL 16: node-driven WASM hash equals
the server's content_hash for a 20 MB file; by-hash returns 201 in ~10 ms
warm with a 151-byte request (vs 20,971,873 bytes for the byte upload);
the copy downloads byte-identical and the manifest ref_count goes 1→2;
a second user probing the same hash gets exists:false and 404 plus the
audit line; duplicate name → 409, malformed hash → 400; worker and wasm
are served with correct MIME (application/wasm).

Every folder navigation awaited rebuildBreadCrumb() — one sequential
fetch per ancestor level — before requesting the first page, so a
depth-8 folder paid ~8 RTTs of dead time before the content even
started loading. And nothing was cached: navigating between sibling
folders re-fetched the same ancestors every time.
- filesModel: session cache id → FolderItem for breadcrumb resolution
(warm navigations rebuild the trail with zero fetches), invalidated
on rename/move (single + batch) via invalidateFolderMeta. The trail
is now built locally and committed atomically, guarded by a
generation token so a rebuild superseded by a faster follow-up
navigation can no longer interleave writes into the newer trail.
- filesView.loadFiles: the rebuild runs concurrently with the first
page fetch; crumbs, history and title update when it resolves.
Navigation latency becomes max(listing, ancestor chain) instead of
their sum — and ~equal to the listing alone once the cache is warm.
The home-folder fallback for inaccessible targets is preserved by
reloading the listing when the rebuild had to reset app.currentPath.

Four related fixes to stop buffering files in page memory and stop
hammering layout from the selection paths:
- Inline viewer media: video/audio fetched the ENTIRE file into a blob
before the first frame (a 2 GB video = 2 GB of tab heap, no
progressive playback, no seek). The <video>/<audio> src now points
straight at the same-origin API URL — cookies travel automatically
and the browser streams with native Range requests, exactly like the
music player already did.
- Downloads (file, folder ZIP, batch ZIP, viewer button): the
fetch → blob → objectURL pattern materialized the whole payload in
RAM before the save dialog appeared (a 10 GB batch ZIP risked
crashing the tab) with no download progress UI. New shared
utils/download.js hands the URL to the browser, which streams to
disk with its own progress UI. Batch download uses the existing GET
endpoint (same URL contract as the drag-out DownloadURL, now shared
via buildBatchDownloadUrl); selections whose id list cannot fit in a
URL keep the buffered POST fallback. Trade-off: failed downloads now
surface in the browser's download shelf instead of an in-app toast.
- Rubber-band lasso: every mousemove (>100/s) walked all cards
interleaving getBoundingClientRect() reads with class writes — up to
N forced reflows per event, freezing the frame rate on folders with
thousands of loaded rows. Card rects (+ item info) are now snapshot
once per drag (rebuilt on scroll), and a single rAF pass per frame
compares against the cached geometry, touching only cards whose
selection state changed.
- batchToolbar: getSelection() rebuilt the selection by scanning every
.file-item in the document (the TODO admitted it); it now reads the
_selected Map that every selection path already keeps in sync.
clear() scopes its DOM sweep to #files-list (the only container the
toolbar manages) instead of the whole document.

`uploadFiles` sent files one at a time (await per file), so dropping N
files meant N sequential round-trips. Reuse the bounded-concurrency pool
already proven in `uploadFolderEntries` (CONCURRENCY = 10): independent
files now upload up to 10 at a time — ~10x faster for many small files.
Per-file progress (XHR → bell), the legacy progress bar, timeout
notifications and the quota short-circuit are preserved. On a quota error
the pool stops pulling new files while in-flight uploads finish (matching
`uploadFolderEntries`) instead of the old hard `break`.

- protect file_management_service::rename_file with validate_storage_name
- remove specific rename modal and use the generic modal class (less duplicate)
- handle errors on modal action: do not close the modal on error and display this error
- hide "Go to parent folder" contextMenu if section is files and folder is the same as current one
- change worker: do not cache html pages (not necessary)
- remove use of window.XXX and maximize import/export,
this will provide more clarety,
show circular dependencies + you will benefit IDE help
The folder upload path (uploadFolderEntries) used a flat 10s fetch
timeout for all files regardless of size. Large files like .CR2 RAW
images (~25MB) on slower networks (e.g. Raspberry Pi) exceeded this
timeout, causing the AbortController to kill the request before the
server received the full body — hence no server logs and 'unknown
error' on the frontend.
Changed to size-scaled timeout: 30s base + 2s per MB (min 10s).
A 25MB CR2 now gets ~80s instead of 10s.
