Re-uploading a partially-uploaded folder used to surface hundreds of spurious
"already exists" failures, and a file the watchdog aborted (or one the server
committed just before the client gave up) was lost.
Backend — save_file_with_blob_impl (the shared write path for both plain and
by-hash uploads): on a name conflict (23505), if the existing non-trashed file
holds byte-identical content (same folder, same name, same blob hash), return
that file as success instead of erroring. A different-content clash still
conflicts. Re-upload / re-sync becomes a clean no-op for everything already
stored — only the genuinely missing files transfer.
Frontend — uploadWithRetry: each file gets one automatic retry on a transient
failure (quota is never retried). With backend idempotency, retrying an
already-stored file is an instant no-op and a stalled/aborted file gets a real
second chance, so a folder upload self-completes instead of leaving gaps.
cargo test: 448 passed. npm run check: clean, 58 tests.

A folder upload with several large files could appear frozen for ~2 min: a few
concurrent uploads stalled and the old 120s per-file timeout neither aborted the
request (leaving zombie XHRs that exhaust the browser's per-host connection pool)
nor recovered quickly.
- uploadFileWithProgress now self-aborts on a stalled connection: the deadline
resets on every upload-progress tick (a slow but *moving* transfer is fine),
and once the body is sent the server gets a fixed window to respond; on a stall
xhr.abort() frees the connection immediately — no zombie, no cascade.
- Lower upload concurrency 4 -> 3 to reduce server contention from large
concurrent uploads.
- The outer per-file timeout is now just a generous backstop for a wedged delta
worker / by-hash request.

Backend:
- POST /api/dedup/check-batch — returns the subset of submitted whole-file
BLAKE3 hashes the caller already owns, in one query (user-scoped,
anti-enumeration via idx_files_blob_hash). Lets a client learn which of N
files it can skip with a single round trip.
(dedup_service::user_owned_blob_references, dedup_handler, routes) + tests.
Frontend — upload pipeline:
- Instant ("by-hash") upload for content the caller already owns: hash every
in-band file, ONE /api/dedup/check-batch, create the owned ones with zero
content bytes, upload only the rest. Covers all sizes below the 8 MB delta
threshold (delta handles larger files). vendor/hashWasm computes the
whole-file BLAKE3 on the main thread.
- Resilient parallel uploads: bounded concurrency (4) + a per-file deadline,
so one stuck/slow/failing file no longer freezes the whole batch — it blocks
only its own lane and times out / is skipped while the rest proceed. Quota
exhaustion stops the run early; partial results are reported ("N uploaded,
M failed").
- Folder uploads (uploadTree) show live bell progress + a final result and go
through the same dedup + parallel pipeline.
- Storage bar ("Almacenamiento") refreshes after uploads/deletes
(session.refresh) instead of showing the stale login value.
Frontend — i18n / UI fixes:
- Fix literal {{count}} and {{percentage}}/{{used}}/{{total}} (param-name
mismatches) in the selection toolbar and storage line; add es strings.
- Remove the underline on user-menu link rows.
Benchmark (uploadStrategies.bench.test.ts) compares baseline / per-file / batch:
the batch collapses N per-file probes into one check (e.g. a WAN 1000-file run
drops from 1700 to 1001 round trips) while matching per-file's byte savings.
Also includes in-progress group virtual-description i18n work present in the
working tree (groups.ts, ResourceList, locale `groups` keys).
Verified: cargo clippy -D warnings (clean), backend 448 tests; frontend
npm run check (clean), 58 unit tests.

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.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
- photos: generate + upload the three video-thumbnail sizes in parallel via
Promise.allSettled instead of a sequential await loop; previewData is still
captured before its upload so the local preview survives a failed upload.
- useOwnerCache: resolve the batch, then apply a single reactive assignment
to `#names` instead of spread-copying the record once per id (fewer copies
and fewer derive re-runs on large resolves).
- admin: migration status polling slowed from 2s to 5s.
- files store: soft cap (10k) on the per-item selection toggle. Bulk
"select all" in the views is intentionally left uncapped.
The three tiers had collapsed to one identical value (#5e6a78 / #9fadbe),
so hints, metadata, timestamps and placeholders were all indistinguishable.
Re-separate them into three perceptibly distinct steps, each verified WCAG
AA >=4.5:1 on every page/surface/hover/muted background in both light and
dark mode. Emphasis maps to contrast: muted is strongest (general secondary
text), faint the weakest (timestamps/placeholders) sitting on the AA floor;
secondary stays clearly stronger than all three. The dark floor is binding,
so the dark steps separate upward (lighter = more emphasis).

Friendly/warm direction, modernised:
- Buttons: drop the translateY lift on every variant (it read jittery and
dated). They now rest on a soft neutral elevation, bloom their warm brand
glow in on hover, and scale-down 0.98 for a tactile press. Motion uses the
--motion-base / --ease-standard tokens.
- Scrollbar: neutral padded pill at rest that warms to the accent on hover,
instead of an always-orange thumb that competed with content.
- page-sticky-header: replace the magic top: -20px (coupled to the content
gutter) with calc(-1 * var(--space-5)); tokenise its z-index to --z-sticky.

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.

Last parity gap from the VanillaJS → Svelte migration (issue #500),
frontend-only — the backend endpoints already exist.
- Drag-out download: onItemDragStart now also sets the DataTransfer
`DownloadURL` type, so dragging a row/selection onto the OS desktop
downloads it — a single file directly (GET /api/files/{id}), a folder as a
zip (GET /api/folders/{id}/download?format=zip), and a multi-selection as
one server-zipped archive via the GET twin GET /api/batch/download
(DownloadURL can only point at a GET URL). The zip name is shared with the
in-app batch download via a new batchZipName() helper.
- Folder drag-drop upload: onDrop now walks dropped directory trees with
webkitGetAsEntry/createReader into {file, relativePath} rows and recreates
the tree server-side, instead of dropping only a folder's top-level files.
The recursive-upload core is extracted into uploadTree() and shared with the
folder picker (onUploadFolder), so both paths behave identically. Plain
multi-file drops keep the existing flat fast-path.
Stacked on #502 (shares onItemDragStart). Frontend gate green (svelte-check
0/0, eslint, stylelint, prettier) + 47 Vitest.

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.

Two parity gaps from the VanillaJS → Svelte migration (issue #500):
1. URL anchor when viewing a file. Opening a file now writes `?file=<id>`
to the URL, so a preview is bookmarkable, reload-restorable, and
Back/Forward open/close it. The viewer is driven from the URL via two
effects (URL→viewer with `untrack` so a user close can't be re-opened;
viewer→URL to drop the param on close with replaceState). Replaces the
write-less, load-only `maybeOpenDeepLink` (the `?file` reader that was
effectively dead because nothing ever set the param).
2. Multi-selection drag ghost. Dragging more than one item now sets a custom
drag image: a stack of the first few rows plus a count badge, reusing the
already-ported but orphaned `.drag-preview`/`.dragged-items`/
`.dragged-items-badge` styles. Previously a multi-item drag showed only the
browser's default single-row ghost with no count.
Also adds `static/geo/` to .prettierignore (the bundled minified world
basemap from #499 is a data asset and must stay byte-faithful — it was
failing `prettier --check`, blocking the gate).
Frontend gate green: svelte-check 0/0, eslint, stylelint, prettier, 47 Vitest.

The normalized cursor-paginated /resources API is live and the bundled
frontend already uses it for favorites, recent, trash and grants. These five
deprecated old-format endpoints had no remaining frontend or protocol
consumers (the Nextcloud handlers call the service layer directly, not these
HTTP routes), so remove them for a uniform API and less duplicate listing
logic:
- GET /api/folders/{id}/contents → use /api/folders/{id}/resources
- GET /api/folders/{id}/contents/paginated → use /api/folders/{id}/resources
- GET /api/favorites → use /api/favorites/resources
- GET /api/recent → use /api/recent/resources
- GET /api/trash → use /api/trash/resources
Removes the HTTP handlers, their routes, OpenAPI path registrations, and the
now-dead list_folder_contents{,_paginated}_impl helpers + unused imports. The
underlying service methods (favorites_service.get_favorites,
trash_service.get_trash_items, etc.) are KEPT — the Nextcloud OCS/trashbin
handlers depend on them.
Deliberately NOT removed: GET /api/folders/{id}/listing. It is still the Files
view's primary data path and offers ETag/304 conditional caching plus
one-shot favorite/share badge sets that /resources does not yet provide;
migrating it needs a separate parity pass on /resources first.
Updates the OpenAPI structure test and the two docs that referenced the
removed paths. `cargo clippy -D warnings` clean; 443 lib tests pass; OpenAPI
regenerates with the 5 paths gone and the /resources replacements present.

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).

Geotagged photos never appeared in Photos → Places because their GPS was
silently dropped. Capture-metadata extraction read GPS/camera/dimensions
only from kamadak-exif, which rejects many real-world EXIF blocks (phones,
photo editors, anything with a non-standard trailing IFD) with
`InvalidFormat("Unexpected next IFD")` and returns nothing. nom-exif —
already used to upgrade the capture date and far more lenient — parses those
same files fine, so only the date survived and latitude/longitude stayed
NULL.
nom-exif now also reads GPS (and the date) and `merge_image_metadata`
combines both sources:
- nom-exif's tz-correct date wins when present (unchanged behaviour);
- nom-exif's GPS only fills gaps kamadak left, so kamadak still wins when it
parsed the file (no regression);
- when kamadak fails outright, a record is still produced from nom-exif's
date/GPS instead of being discarded.
Existing photos can be backfilled via POST /api/admin/photos/metadata/reextract.

`.nav-item` was ported from a <button> but the new AppShell renders it as
an <a>, and the rule carried every button reset except `text-decoration`.
With no global anchor reset, the nav rows (Files, Shared, Recent, …) showed
the browser's default link underline. Add `text-decoration: none` to the
base rule (covers normal, hover and active states).

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 global `script-src 'self'` CSP header blocked every inline <script>,
so the SvelteKit hydration bootstrap never ran and the SPA never mounted
(blank page behind the splash spinner). The anti-FOUC theme init in
app.html was blocked too.
Instead of weakening the policy with 'unsafe-inline', the backend now
builds `script-src` at startup from 'self' plus a SHA-256 hash of every
inline <script> in the served HTML shells. The policy stays strict (no
'unsafe-inline' for scripts) and the hashes are recomputed from the built
assets on each startup, so a frontend rebuild needs no header edit — even
though SvelteKit's bootstrap hash changes every build.
- web::content_security_policy builds the header; web::resolve_static_path
is extracted so serving and hashing read the exact same bytes.
- byte-exact inline-script extraction (skips src= externals), unit-tested
against a known SHA-256 vector and extraction edge cases.

The SvelteKit migration gated build.rs's static-dist/OUT_DIR generation
behind OXICLOUD_RUST_ASSETS=1 (early return), but login_v2_handler.rs
still embedded the page with
`include_str!(concat!(env!("OUT_DIR"), "/nextcloud-login.html"))`. With
OXICLOUD_RUST_ASSETS unset (the default), that file is never written to
OUT_DIR, so a clean `cargo build` failed to compile. (#489)
Migrate the page off include_str! to an askama template
(templates/nextcloud/login.html), mirroring the existing
DrivePickerTemplate in the same handler. This drops the only
compile-time dependency on the legacy build.rs pipeline, so the
OXICLOUD_RUST_ASSETS=1 CI workaround is no longer needed and is removed
from ci.yml, load-smoke.yml and load-nightly.yml.
Also fix the second failure on #489: with OXICLOUD_RUST_ASSETS=1 the
release pipeline panicked in copy_dir_recursive because `static/locales`
is now a symlink to frontend/static/locales. entry.file_type() reports
the link itself (not its target), so the symlinked directory was routed
to fs::copy and failed with "the source path is neither a regular file
nor a symlink to a regular file". Classify entries with fs::metadata,
which follows symlinks, so symlinked directories are traversed.
static/nextcloud-login.html is removed (its content moved into the
template; no other consumer) and dropped from build.rs HTML_INCLUDE.

The app is a pure client-rendered SPA (ssr=false, adapter-static), so until the
JS bundle downloads, parses and mounts, the page is blank — only then does the
layout's own loading state appear. True route prerendering would mean turning on
SSR, an architectural change at odds with the SPA design.
Instead, bake a tiny boot splash into the shell (`app.html`): a centered spinner
that paints the moment the HTML is parsed — before the app bundle or its CSS
load — covering the blank gap. The root layout removes `#app-splash` the instant
it mounts (before `session.load`), so public routes like /login (which render
without waiting for the session) appear immediately and protected routes hand
off to their own loading UI. `light-dark()` plus early `color-scheme` rules make
the splash match the resolved theme (incl. the saved override), so there's no
colour flash when the app CSS arrives; it respects `prefers-reduced-motion`.
Pure HTML/CSS in the shell — no new requests, no JS framework on the critical
path, ~0.6 KB in index.html. Verified on the real static-dist build in headless
Chromium: the shell ships `#app-splash`, the layout removes it after mount, the
app renders, and there are no runtime errors.

`initI18n` runs in the client `init()` hook and blocks the first render. For
every non-English user it awaited TWO locale dictionaries back to back — the
active locale AND `en` (the fallback) — so first paint waited on two sequential
round-trips + JSON parses.
Now it awaits only the active locale, then warms `en` in the background
(non-blocking). `t()` only consults `dicts.en` for keys the active locale is
missing, and most call sites already pass an inline English fallback, so the
deferred `en` doesn't change what users see; when it arrives `dicts.en` is
reactive, so any key that fell through re-renders. English users are unchanged
(no second fetch was ever needed).
Net: non-English startup drops from two blocking locale fetches to one, halving
the i18n payload on the critical path (the server already serves these JSONs
brotli/gzip-compressed via the global CompressionLayer, so the wire cost was
already small — this removes the extra round-trip + parse from first paint).
Validated: new unit test (initI18n resolves while the en fetch is still pending,
en is kicked off in the background, and a key missing from the active locale
falls back once en lands) → 47 frontend tests green; npm run check; prod build.

Every navigation rebuilt the breadcrumb with one `GET /api/folders/{id}` per path
segment (a depth-D folder = D requests, each no-store) purely to label the trail.
Add an id→name cache, populated wherever a name is already known:
- every listing names its children, so `cacheFolder` records them, and
- `getFolder` records the folder it fetched.
`buildCrumbs` now reads names from the cache and only fetches the ids it hasn't
seen. During normal step-by-step navigation each ancestor was named by its
parent's listing, so the breadcrumb resolves with ZERO extra requests; only a
cold deep-link fetches its unknown ancestors (still in parallel). Folder renames
update the cache immediately so the trail stays correct.
The cache is a small LRU (cap 1000 — names are tiny) and is independent of the
listing cache (names survive a listing invalidation).
Validated: 3 new unit tests (listing populates child names, getFolder records,
rename overwrites) → 46 frontend tests green; npm run check; headless render of
the real files route (list + grid) — no errors.

Every folder navigation re-downloaded the full listing: `listFolder` cache-busted
with `?t=<ts>` + `Cache-Control: no-store`, so back/forward and re-entering a
folder always paid a full round-trip + payload.
Now the files browser caches listings in memory and serves SWR:
- On navigation it paints a previously-visited folder instantly from cache, then
revalidates with `If-None-Match` (the backend ETag covers folders + files +
favorite/share badges, so it's a faithful validator). Unchanged → 304 with an
empty body; changed → 200 refreshes cache + UI.
- A generation token guards against a slow in-flight response clobbering a newer
navigation; breadcrumbs now resolve independently so they never block the grid
paint.
- Mutations (create/upload/rename/move/copy/delete, incl. the move dialog) go
through `reload()`, which drops the cache and refetches fresh — no stale view
after an action.
API layer (`folders.ts`):
- `fetchFolderListing(id, { etag?, forceRefresh? })` does the conditional fetch
(200 → parsed listing + ETag, 304 → empty); `listFolder` stays as a
non-conditional wrapper for the move-dialog tree.
- A small LRU (cap 40) cache with `getCachedFolder` / `cacheFolder` /
`invalidateFolderCache`. `cache: 'no-store'` keeps the browser HTTP cache out
of the way; revalidation is driven entirely by our own ETag.
Net: instant back/forward navigation, and an unchanged folder revalidates with a
0-byte 304 instead of re-downloading the whole listing. Validated: 7 new unit
tests (conditional If-None-Match + 304, LRU eviction/recency, invalidation),
npm run check, and a headless render of the real files route (list + grid).
