Follow-up to the adversarial re-review of the audit-fix branch.
MUST-FIX:
- H3: bound aggregate upload RAM. The body limit alone didn't cap concurrency,
so ~N parallel 550MB uploads could OOM the box. Add an Arc<Semaphore>
(UPLOAD_MAX_CONCURRENCY=4) in AppState, acquired at the top of the upload
handler before the multipart body is read, so waiting requests hold only a
connection — peak buffered RAM ≈ 4×550MB. (Matches the CompressionWorker
semaphore pattern; avoids tower's non-default `limit` feature.)
- M8: release_gallery now runs the claim UPDATE + both job INSERTs in one
transaction, so the row lock is held until the jobs exist — closing the
cross-table TOCTOU where two concurrent presses could both spawn workers
racing the same output files. Export temp filenames are now per-run
(Gallery.{uuid}.zip.tmp, viewer_tmp_{event}_{uuid}, Memories.{uuid}.zip.tmp)
so overlapping runs can't truncate each other. Final served names unchanged.
- M11: 'user-banned' was missing from sse.ts KNOWN_EVENTS, so EventSource
silently dropped the frame and the forced-logout handler never fired. Added.
SHOULD-FIX:
- M8-3: re-release is now allowed when nothing is in progress and at least one
job failed (was: only when *every* job failed), so a one-sided failure (zip
done, html failed) is no longer permanently unrecoverable.
- M18: two light-mode contrast spots the earlier sweep missed — the LightboxModal
char-counter class: directives and the account PIN-missing notice.
- M15: the diashow auto-advance is now slowed to a ≥30s floor under
prefers-reduced-motion (WCAG 2.2.2), making the app.css comment accurate.
Verified: cargo build + 6 tests, npm run check (0 errors), and a live smoke test
against Postgres — first release 204, second 400, one-sided-failure re-release
204, no SQL errors; a normal upload still returns 201 through the new permit.

M13: add viewport-fit=cover so env(safe-area-inset-*) resolves on notched phones.
M14: like buttons (list card, grid overlay, lightbox) get aria-pressed + a
descriptive aria-label so AT announces self-state, not just the shared count.
M15: a prefers-reduced-motion media query neutralizes the decorative keyframes
(Ken Burns, crossfade, HeartBurst) and snaps transitions.
M16: join/recover name + PIN inputs and the lightbox comment input get aria-labels.
M17: FeedGrid overlay like/comment buttons get aria-labels and ≥44px hit areas.
M18: bump light-mode secondary text from gray-400 to gray-500 (keeping
dark:text-gray-400) across the app for WCAG AA contrast.
Also raises the PIN inputs to 6 digits (placeholder, maxlength, slice, and the
auto-submit threshold) to match the new 6-digit generated PINs; legacy 4-digit
PINs still submit via the button.

H11: UploadSheet now honors the modal contract — role=dialog/aria-modal +
accessible name, a focus-trap/Escape/focus-restore $effect mirroring
ContextSheet, and inert + pointer-events-none when closed so its controls leave
the tab order and AT tree.
H12: a layout-level $effect toasts each upload-queue item the first time it
transitions to 'error', so a banned/locked/over-quota guest is actually told
why their photo didn't post instead of the composer silently closing.
M10: api.ts now redirects to /join after clearAuth() on a 401 (guarded against
loops on the auth screens), so a 401 no longer strands the user on a dead page.
M11: ban and event-lock are pushed to guests. A new uploadsLocked store is
seeded from /me/context (now exposes uploads_locked) and kept live by
event-closed/opened SSE; the feed shows a banner and the FAB is disabled when
locked. A user-banned SSE event force-logs-out the targeted user.
M19: feed and export pages track a distinct loadError and render an "Erneut
versuchen" retry card instead of collapsing a fetch failure into "empty" /
"not released". Light-mode empty-state text bumped to gray-500 for contrast.

H6: migration 006 replaces v_feed's double LEFT JOIN + COUNT(DISTINCT) (which
materialized a likes×comments Cartesian per upload) with correlated scalar
subqueries that each use their own index. Output columns are unchanged, so
feed + hashtag-filtered paths both benefit.
H7: feed_delta now applies the feed rate limit (keyed per user), caps results
at 200 rows, and clamps how far back a client `since` may reach (7 days). When
clamped or capped it returns reload_required=true; the SSE client turns that
into a full feed reload instead of streaming the whole gallery through the view
on every tab refocus.
M9: the SSE reconnect cursor is now advanced only from server timestamps (an
upload's created_at, seeded from the feed and updated on new-upload events and
delta responses), never the client clock — so a skewed phone clock can't drop
events missed while backgrounded.

Replaces the DB-blind `/media` ServeDir with a signed, DB-aware gateway at
`GET /media/{kind}/{id}`. Every media byte now flows through an HMAC-SHA256
signature check (minted into feed/upload DTOs for authenticated members; <img>
can't carry a Bearer header) plus a DB lookup:
- C1: export ZIP/HTML have no upload row, so they are unreachable by path —
download stays behind the authenticated /export endpoints.
- C2 (sink): responses carry X-Content-Type-Options: nosniff and a locked-down
CSP (default-src 'none'; sandbox), neutralizing any active content.
- C3 / H2: find_by_id filters deleted_at and the handler rejects ban-hidden
uploaders, so deleted and moderated artifacts 404 — and the unauthenticated
get_original alias (the H2 hole) is removed entirely.
- H10: delete paths (owner + host) now unlink original/preview/thumbnail after
commit; soft_delete returns the paths; an hourly reaper reclaims disk for
rows soft-deleted past a 1-day grace and hard-deletes them (FKs cascade).
Signed URLs are bucketed to a 1h window so they stay stable across feed polls
(browser cache hits) while expiring within 24h. media_token sign/verify has a
unit test (roundtrip + tamper + expiry).
Frontend: FeedUpload/pickMediaUrl now use the backend-provided signed
original_url; no client constructs a media path anymore.

H1: AuthUser now JOINs session→user and sources role/ban/event from the live
DB row instead of trusting JWT claims. Bans take effect on the next request;
demotion/promotion is immediate. Adds Session::find_auth_context and rejects
tokens whose sub/event_id disagree with the session row. This also closes M2
(banned export) and M3 (banned edit/delete) globally — banned users can no
longer pass the AuthUser extractor.
Adds Session::delete_by_user_id and revokes all of a user's sessions on
ban_user, set_role, and reset_user_pin so existing JWTs die immediately.
ban_user also emits a user-banned SSE for forced client logout.
H9: reset_user_pin used a non-existent column pin_failed_attempts (runtime
sqlx, so it 500'd in prod). Corrected to failed_pin_attempts — the only
account-recovery path now works.
C4: LightboxModal posted comments to /comment (singular); backend only
registers /comments. One-character route fix re-enables the comment feature.

Follow-up to the comprehensive code review. Five batches:
1. Cross-event authorization: host_delete_upload, unban_user, and
host_delete_comment now scope by auth.event_id. Adds
Upload::find_by_id_and_event / soft_delete_in_event and a
Comment::soft_delete_in_event variant that joins through upload.
2. Token exposure: SSE auth no longer puts the JWT in the URL.
New /api/v1/stream/ticket endpoint mints a short-lived single-use
ticket bound to the session; the EventSource passes ?ticket=...
instead. Refuse to start in APP_ENV=production with the dev JWT
sentinel; warn loudly otherwise.
3. Account hardening: per-IP+name rate limit on /recover (mitigates
targeted lockout DoS), per-IP rate limit on /admin/login, random
32-char admin recovery PIN (replaces "0000"), structured tracing
events for wrong PIN, lockout, failed admin login, ban/unban/role
change/pin-reset/host-delete.
4. DoS / correctness: comment listing paginated (LIMIT 50 + ?before=
cursor), hashtag extraction whitelisted to ASCII alnum+underscore
(≤40 chars) with unit tests, display_name / caption / comment body
length validated in chars rather than bytes.
5. Cleanup: session-touch failures now logged, DATABASE_MAX_CONNECTIONS
env var (default 10).

Wires up everything from the previous commits into actual UI surfaces, and
applies Tailwind dark: variants throughout. All pages now support the
'system' / 'light' / 'dark' preference set in the onboarding step or in
Mein Konto → Design.
Layout & nav:
- routes/+layout.svelte: initTheme(), global pin-reset SSE handler that
filters by user_id and calls clearPin(), one-shot /me/context fetch
on boot to hydrate privacyNote + quota.
- components/BottomNav.svelte: dark variants on the frosted-glass bar.
- components/UploadSheet.svelte: dark variants on backdrop, sheet,
source buttons.
- components/OnboardingGuide.svelte: new "Helles oder dunkles Design?"
step (3-option custom-radio grid), reactive currentStep with proper
type narrowing, dark variants throughout. Privacy-note nudge appears
on the PIN step only when one is configured.
Feed:
- routes/feed/+page.svelte: diashow entry icon (tablet/desktop only),
long-press → ContextSheet (Löschen for own posts, Original anzeigen
for all), upload-deleted + feed-delta SSE handlers, dark variants on
header, search, autocomplete, filter chips, empty states.
- components/FeedListCard.svelte: long-press wireup, double-tap-to-like,
data-mode-aware mediaSrc via pickMediaUrl, kebab fallback for desktop,
isOwn prop, dark variants.
- components/FeedGrid.svelte: long-press wireup, dark variants.
- components/LightboxModal.svelte: data-mode-aware src, double-tap heart
burst, dark variants on card / comments / input.
- components/HashtagChips.svelte: dark variants.
Account:
- routes/account/+page.svelte: theme picker (3-button radio grid), data
mode picker (with confirm sheet for Original), live quota widget,
preformatted Datenschutzhinweis block, diashow tile (mobile only),
pin now sourced from the $currentPin store so a global pin-reset
clears it live, clearQueue() on explicit logout, dark variants
across every card + both bottom sheets.
Upload:
- routes/upload/+page.svelte: per-user quota progress bar above the
submit button, dark variants.
Host & Admin:
- routes/host/+page.svelte: PIN-reset confirm + one-time PIN modal,
hosts may demote other hosts, canResetPinFor() helper, dark variants
on all cards, modals, stats, toast.
- routes/admin/+page.svelte: Config form rebuilt as CONFIG_GROUPS with
per-field kind (number / bool / text), renders toggles for the
rate-limit + quota switches and a textarea for the privacy_note;
Nutzer tab gains PIN reset + hosts-may-demote-hosts wiring; same
one-time PIN modal; dark variants everywhere.
- routes/admin/login/+page.svelte: dark variants.
Join / Recover / Export:
- routes/join/+page.svelte: rename inline link to
"Ich habe bereits einen Account", dark variants.
- routes/recover/+page.svelte: dark variants.
- routes/export/+page.svelte: dark variants on status cards + HTML
guide modal.

A fullscreen auto-advancing slideshow any user can start. Design:
docs/CONCEPT_DIASHOW.md.
- lib/diashow/queue.ts: SlideQueue state machine — liveQueue drains first
(FIFO, seeded by SSE upload-processed), then shuffleQueue (refilled
from allKnown minus a 5-id ring buffer of recently shown). Pure logic,
unit-testable.
- lib/diashow/wakelock.ts: Screen Wake Lock wrapper that re-acquires on
visibility change (the OS drops the lock when the tab hides).
- lib/diashow/transitions/{index,crossfade,kenburns}.ts: registry +
the v1 transitions. Adding a new animation is one file + one entry —
the extensibility target from docs/FEATURES §2.9.
- routes/diashow/+page.svelte: fullscreen page, hides bottom nav,
6 s default dwell (3/6/10 configurable), keyboard shortcuts
(Escape exits, Space toggles pause), tap-to-reveal overlay with
pause / dwell / transition / exit. Respects $dataMode to choose
preview vs. original URL.

The plumbing layer the v0.16 UI features (and dark mode) build on.
Shared design tokens (Tailwind v4):
- tailwind-theme.css (new): @custom-variant dark (class-driven, beats OS
default) + @theme color/font/radius tokens + baseline html/html.dark
rules so any page that hasn't been re-themed still renders the right
body bg + color-scheme.
- src/app.css + export-viewer/src/app.css now import the shared theme.
- src/app.html: 6-line FOUC guard sets <html class="dark"> before paint
(mirrored from theme-store.ts) so dark reloads no longer flash white.
Adds <meta name="theme-color"> kept in sync by initTheme().
Cross-cutting stores (one per concern, per docs/FEATURES §2.9):
- data-mode-store.ts: 'saver' | 'original' per-device, plus pickMediaUrl
helper so feed cards / lightbox / diashow all resolve URLs the same way.
- privacy-note-store.ts: hydrated from /me/context, refreshed on SSE
event-updated.
- quota-store.ts: { enabled, used, limit, active_uploaders, free_disk },
refreshed after each upload completes.
- theme-store.ts: 'system' | 'light' | 'dark' preference + derived
appliedTheme + initTheme() that syncs <html class>, localStorage,
and the theme-color meta. Listens to prefers-color-scheme.
- auth.ts: currentPin writable mirror + clearPin() helper called from
the global pin-reset SSE handler — fixes the stale-PIN bug where the
localStorage copy survived a reset.
DTO mirror:
- types.ts: QuotaDto, MeContextDto, PinResetResponse, DeltaResponse each
carry a `// mirrors backend/...` comment per the lib README convention.
SSE client:
- sse.ts: KNOWN_EVENTS registry (one entry per server-emitted type),
synthetic feed-delta dispatched after foreground reconnect via the
/feed/delta?since= endpoint, exponential backoff (1 → 60 s + jitter)
on errors, attempt counter reset on user-initiated visibility resume.
Upload queue:
- upload-queue.ts: IDB schema bumped to v2 — entries tagged with userId;
loadQueue filters by current user (no cross-user leak on shared
devices); uploadItem refuses to upload an entry whose userId differs
from getUserId() (defense-in-depth); new clearQueue() called on
explicit logout. v2 upgrade wipes pre-v2 entries (no userId, can't
attribute safely).
Mobile primitives:
- actions/longpress.ts: 500 ms hold with 10 px move tolerance, swallows
the next click + the right-click contextmenu so the gesture doesn't
double-fire the inner button's onclick.
- actions/doubletap.ts: tap-pair detector that preventDefaults the
second tap so iOS Safari doesn't also zoom on double-tap.
- components/ContextSheet.svelte: generic bottom sheet driven by a
ContextAction[] prop. Reused by feed posts, comments, host user rows.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
- PROJECT.md, README.md, TEST_GUIDE.md: status line refreshed; rate-limiter
doc-vs-code drift fixed; HTML export section rewritten for the SvelteKit-
static viewer; SSE event names + new events documented; config seed block
extended with planned toggles + privacy_note; decision log entries added.
- docs/CONCEPT_HTML_VIEWER.md, docs/CONCEPT_MOBILE_UI.md: banner the design
intent as shipped; point at the source-of-truth code paths.
- docs/CONCEPT_DIASHOW.md: planned-then-shipped design for the live diashow
(two-queue policy, pluggable transitions, data-mode aware).
- docs/FEATURES.md: capability matrix by role (Guest / Host / Admin) plus
prose per area (auth, posting, feed, moderation, admin, export, gestures,
data mode, quotas, privacy note, extensibility).
- docs/USER_JOURNEYS.md: step-by-step flows for every supported scenario,
including PIN reset by host, data mode, privacy note, gestures, and the
admin toggles.
- docs/IDEAS.md: speculative extensions (global diashow, reactions,
multi-tenancy, animation pack, etc.) — explicitly out of v0.16 scope.
- backend/migrations/README.md, frontend/src/lib/README.md: codify the
"never edit a shipped migration" rule and the lib/ conventions
(one store per concern, gestures via actions, sheets via ContextSheet,
transitions as drop-in components).

Backend: rate limiter gains check_with_retry() returning seconds until
the next slot opens. Upload 429 responses include retry_after_secs in
JSON and a Retry-After header.
Frontend: upload queue catches 429 as RateLimitError, resets affected
item to pending, schedules processQueue() for the server-reported delay,
and shows a live countdown banner in the queue UI.

Add 4-step dismissible onboarding overlay shown on first feed visit
(welcome, upload, hashtags, PIN importance). Dismissed state persisted
in localStorage under eventsnap_guide_seen. Step indicator dots and
skip/continue buttons included.
Update HTML export guide modal to persist the eventsnap_html_guide_seen
flag: first download shows the instructions modal; subsequent clicks go
straight to download without interruption.

Add /account route showing display name (from localStorage), role badge,
session expiry decoded from JWT, and recovery PIN display with copy button.
Join and recover flows now persist display_name to localStorage via setAuth().
Feed header logout button replaced with person-icon link to /account;
logout is available from the account page.

Add Host Dashboard for event and guest management, accessible at /host.
Backend — new /api/v1/host/* endpoints (RequireHost auth):
- GET /host/event → event name + lock/release state
- POST /host/event/close|open → lock or unlock uploads; SSE broadcast
- POST /host/gallery/release → set release timestamp, enqueue export jobs
- GET /host/users → all guests with upload count & bytes
- POST /host/users/{id}/ban → ban with optional upload-hide choice
- POST /host/users/{id}/unban → lift ban
- PATCH /host/users/{id}/role → promote guest→host or demote host→guest
- DELETE /host/upload/{id} → host-level soft-delete + SSE
- DELETE /host/comment/{id} → host-level soft-delete
Frontend — /host page:
- Event controls: lock/unlock toggle and release-gallery button with status badges
- Guest table: display name, role badge, upload count, storage used
- Ban flow: modal asking whether to keep or hide the user's uploads
- Promote/demote buttons respecting caller role (host can promote guests; admin can demote hosts)
- auth.ts: getRole() decodes JWT payload client-side to gate the route

upload pipeline alongside library-picked files.
- CameraCapture.svelte: fullscreen overlay with live preview, photo
capture (JPEG via canvas), video recording (WebM/MP4 via MediaRecorder),
front/back camera toggle, recording timer, and permission-denied error state
- Upload page: side-by-side "Gallery" and "Camera" pickers; shared
caption/hashtags fields apply to both sources; Blob→File conversion
with timestamped filename before enqueue
- .env.test: reference environment config for local testing
