Follows the perf + security + user-flow work with a role/persona audit (guest, host,
admin, projector) and fixes across three review rounds. Highlights:
HIGH
- Ban now replays on reconnect. A ban isn't a soft-delete, and the `user-hidden` SSE has
no replay, so a client that missed it (esp. the unattended diashow) kept cycling a
banned user's slides. New `uploads_hidden_at` (migration 013) + `hidden_user_ids` in
/feed/delta; feed + diashow evict those users. Applied even on a truncated delta.
MEDIUM
- Locked-upload data loss: a photo staged offline during a lock/release was purged as a
terminal 4xx and lost when the host reopened. New reversible `uploads_locked` error code;
the queue keeps the blob and auto-resumes on the `event-opened` SSE.
- Reopen after release now warns (ConfirmSheet) that it revokes the published keepsake.
- Host "forgotten-PIN" badge updates live (`pin-reset-requested` was broadcast but never
in KNOWN_EVENTS / subscribed); host page also refetches on `pin-reset` so a two-host
race can't hand out a conflicting PIN.
- Ban modal copy fixed (read-only ban, not "session ended"); Degradieren/Sperren/Entsperren
hidden on peer-host rows for non-admins (they always 403'd).
- Host dashboard shows live keepsake generation progress / ready state + link to /export.
- Admin JWT moved to sessionStorage (§11.1) to bound exposure on shared devices.
Export generation guard (H1 from the prior round, hardened): per-(event,type) `release_seq`
(migration 012) with seq-guarded claim/finalize/mark_failed/update_progress, per-generation
temp/final paths, download follows `file_path`, prune only strictly-older generations.
LOW: diashow coalesces upload-processed (avoids self-rate-limit); event-closed reconciles
galleryReleased; /recover gains a forgot-PIN request + drops a stale cached PIN on 401;
delta `>=` tie-break + 429 retry; misc copy/labels.
Adds e2e: ban-replay, upload-lock-code, and rewrites export-reopen-rerelease with a
data-completeness test. Reconciles USER_JOURNEYS §9/§11.
Verified: cargo build clean, 40 unit tests, svelte-check 0 errors, 33 frontend unit
tests, 155 e2e passing on chromium-desktop.

Performance:
- Cache the runtime `config` table in-memory (ConfigCache) with synchronous
invalidation on every write (admin PATCH + test reseed). Was re-reading each
key from Postgres on every request (~8 round-trips per upload).
- Stream uploads chunk-by-chunk to a temp file instead of buffering the whole
body in RAM (peak was up to the per-class cap, e.g. 500 MB/video); only 512
sniff-bytes are kept for magic-byte detection, then atomic rename into place.
- Cache the media-filesystem disk snapshot (DiskCache, 15s TTL) shared by the
quota check and admin stats; drop the discarded System::refresh_all().
- HTML export streams video (and small-image) originals straight into the ZIP
via a manifest instead of copying them to a temp dir first (removed the
transient 2x disk usage) and drops the double directory scan.
- Auth extractor resolves session -> live user in one JOIN (was two queries),
touching last_seen_at by token hash.
Stability:
- SSE: on broadcast lag, emit a `resync` event so the client runs a delta
fetch instead of silently losing events; frontend reconciles adds, deletions,
and (via an in-place refresh) like/comment counts on visible cards.
- Storage quota fails OPEN when the disk can't be read (was a 0-byte limit that
locked out all uploads).
- Graceful shutdown drains in-flight requests on SIGTERM/SIGINT, bounded by a
10s backstop so open SSE streams can't stall a deploy.
- Upload removes the persisted file if the DB transaction fails (no orphaned
bytes with no row to reclaim them).
Tests:
- New pure select_disk() with 5 unit tests (longest-prefix, fallbacks, fail-open).
- New e2e export-video spec covering the HTML export's video-streaming branch.

CR1: the lightbox comment button POSTed to /upload/{id}/comment (singular);
no such route exists, so every UI-submitted comment 404'd and was lost.
Fixed to /comments (plural). The prior e2e passed because its seed helper
POSTs the API directly — added comment-ui.spec.ts which drives the real
component so this can't regress silently again.
CR2: export archives (Gallery.zip / Memories.zip / HTML viewer) were written
under media_path, which is a public ServeDir — so GET /media/exports/
Gallery.zip served the entire event (every photo, caption, comment,
uploader name) to any anonymous visitor at a guessable URL, bypassing the
ticket + release gate. Moved exports to a separate EXPORT_PATH (=/exports)
on its own volume (Dockerfile chown, compose volume, gated handler reads
the new path). export-leak.spec.ts asserts /media/exports/Gallery.zip → 404.
Riders (git can't split hunks): LightboxModal also gains H3 live-eviction on
comment-deleted/upload-deleted; config.rs also wires compression_concurrency
from boot config (medium).

Replace the minijinja-based HTML export with a full SvelteKit static
viewer app. The new export produces a ZIP with:
- Pre-built viewer assets (index.html + JS/CSS bundle)
- data.json with all posts, comments, tags, and like counts
- Processed media: 400px thumbnails for grid, full images (2000px
cap if >5MB), video thumbnails via ffmpeg
Remove minijinja dependency, add include_dir to embed viewer assets
at compile time. Update Dockerfile to copy static/ for builds.

Add async ZIP and HTML offline viewer export workers, download endpoints,
and a guest-facing /export page.
Backend — export workers (tokio::spawn, run after gallery release):
- ZIP worker: streams all non-deleted originals into Gallery.zip via
async_zip (Stored compression), organised into Photos/ and Videos/
with {date}_{uploader}_{id}.{ext} filenames; updates progress_pct in DB
- HTML worker: renders Memories.html via minijinja template (self-contained:
inlined CSS + JS, relative media paths); packs it with README.txt and
all media into Memories.zip (Deflate for text, Stored for media)
- Both workers mark export_job status (running → done/failed), update
export_zip_ready / export_html_ready on the event, and broadcast SSE
export-progress + export-available when both complete
Backend — new endpoints (AuthUser):
- GET /export/zip → streams Gallery.zip if export_zip_ready
- GET /export/html → streams Memories.zip if export_html_ready
- GET /export/status → released flag + per-type status/progress (moved from admin)
Memories.html features: warm keepsake aesthetic, responsive grid, fullscreen
lightbox with captions/comments/likes, client-side hashtag filter chips,
XSS-safe JS, fully offline (no external deps)
Frontend — /export page:
- Locked state: padlock illustration + message
- Released state: ZIP and HTML cards with progress bars (SSE-driven),
download buttons enabled only when ready
- HTML guide modal (unzip instructions + Wi-Fi tip) before download begins
