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.

The audit + fix-verification reports (docs/AUDIT-2026-06-27.md,
docs/FIX-VERIFICATION-2026-06-27.md) are local working artifacts; one was
accidentally swept into the media-gateway commit. Dropped from history and
ignored so they stay untracked local files.

The new v_feed-rewrite migration collided with the existing 006_user_pin_lockout
(versions must be unique). Verified against a fresh Postgres: all migrations
001–010 now apply cleanly on startup.

The failed-attempt counter is no longer reset when the lockout window expires,
so each further wrong PIN past the 3-strike threshold doubles the lockout —
15min, 30, 60, … capped at 24h. Combined with the now 6-digit PIN (1M space),
this makes sustained guessing via /recover infeasible. A successful recovery or
a host PIN reset clears the counter; legitimate users (who don't fail) are
unaffected.

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.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
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.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
M1: toggle_like / add_comment / list_comments now resolve the target via
Upload::find_by_id_and_event, returning 404 for uploads outside the caller's
event or already soft-deleted — closing the cross-event IDOR and the
write-to-deleted-post path.
M3: the redundant in-handler is_banned fetches (upload, like, comment) are
removed; the AuthUser extractor (WS1) already rejects banned users on every
authenticated route, which also covers the previously-ungated edit_upload /
delete_upload / delete_comment.
M8: release_gallery claims the release with a single conditional UPDATE and only
proceeds when it matches a row, so concurrent presses can't spawn duplicate
export workers racing on the same files. Re-release is now permitted when all
prior export jobs terminally failed (e.g. a crash mid-export), and the job
upsert resets failed rows so the workers re-run cleanly.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
H3: re-enable a request-body limit (550MB, sized to the largest allowed video +
multipart overhead) instead of DefaultBodyLimit::disable(), and drop the
second full-file copy by keeping the upload as Bytes.
H4: image decode now goes through ImageReader with explicit dimension
(12000x12000) and allocation caps, rejecting decompression bombs before the
expensive resize, and the whole spawn_blocking is wrapped in a 120s timeout
mirroring the ffmpeg guard.
H8: every bcrypt hash/verify (join, recover, admin_login, host PIN reset) now
runs via spawn_blocking through a new services::password helper, so concurrent
auths can't pin the async workers.
M7: images and videos get independent compression permit pools, so slow videos
can no longer starve image-preview generation.
H5: add a generous per-IP daily account-creation cap (NAT-safe at ~100 guests)
on top of the burst cap, and wire up the previously-dead upload_count_quota_*
config as an event-wide file-count cap that a re-join cannot reset.
Also bumps generated recovery PINs from 4 to 6 digits (part of M4).

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.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
C2: stored-XSS via the application/* MIME bypass is closed — the declared
Content-Type and client filename are no longer trusted. New classify() derives
both the canonical MIME and a safe extension purely from magic bytes against a
strict allowlist (jpeg/png/webp/heic/mp4/mov/webm); anything infer can't
positively identify (incl. HTML/SVG script payloads) is rejected. Unit tests
cover accept + reject paths.
M12: the stored extension can no longer carry '/' or arbitrary client text —
it's one of the allowlist's safe constants, ending directory-pollution and the
export DoS.
M5/M6: quota is now reserved with a single conditional UPDATE that row-locks
(no TOCTOU overshoot) and the reservation + row INSERT run in one transaction;
the file is written before commit and unlinked on any rollback, so a crash
mid-write can no longer leak quota bytes or orphan a row. Upload::create is now
executor-generic to run inside the tx.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
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.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
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).

Adds a Playwright-driven end-to-end test suite under e2e/ with 134 tests
across 9 spec folders, running against an isolated docker-compose test
stack. Mobile-gesture coverage on a Pixel 7 viewport. Cross-UA smoke
matrix including a Tier-A Samsung Internet emulation. CI workflow in
.github/workflows/e2e.yml.
Also ships small fixes surfaced while writing the suite:
Backend
- JWT now carries a `jti` (per-token UUID) so two admin logins in the
same wall-clock second don't collide on session.token_hash UNIQUE.
- join handler rejects 0x00 in display names with a clean 400 (was 500
from Postgres).
- dev-only POST /api/v1/admin/__truncate route, registered only when
EVENTSNAP_TEST_MODE=1.
- rate_limiter.clear() for test isolation.
- Dockerfile: rust:1.88, COPY ./migrations into the build context.
Frontend
- Removed `aria-hidden="true"` from the leave-confirm and data-mode
backdrops on /account (it cascaded into the dialog content and made
Abmelden / Aktivieren unreachable to a11y tools).
- Bumped the PIN-copy button to ≥44×44 px touch target.
- data-testid attributes on ~20 stable interactive elements
(auth + upload routes).
Findings the suite surfaces as `[finding]` warnings on every run:
1. /admin/login has no rate-limit or lockout.
2. PIN-attempt counter races under parallel /recover requests.
3. Zero-byte uploads pass /api/v1/upload.
4. SVG-with-script can pass the magic-byte check.
Final test result: 134 passed / 0 failed / 9 skipped (test.fixme stubs
for planned gestures and one UI-upload-flow investigation).
WebKit/Firefox projects need libavif16 on the host to launch — configs
are in place; install with `sudo apt-get install libavif16` to enable.

- account/+page.svelte: remove `aria-hidden="true"` from the
leave-confirm and data-mode-warning bottom-sheet backdrops. The
attribute cascaded into the dialog children, making the inner
Abmelden/Aktivieren/Abbrechen buttons unreachable in the accessibility
tree (and to Playwright's `getByRole`). Discovered while writing the
E2E suite; the visual layout is unchanged.
- join/+page.svelte: bump the PIN-copy button from `py-1` (28px tall) to
`min-h-11 min-w-11 py-2` so it clears the ≥44px touch-target floor on
mobile. Touch-target audit revealed the gap.
- data-testid attributes on stable interactive elements (join name input,
join submit, PIN modal + copy + continue, recovery PIN + submit + try-
different-name, admin login password + submit + error, recover name +
PIN + submit + error, upload header submit + sticky submit + caption
textarea). Targeted at ~20 spots where semantic locators were ambiguous
(e.g. two "Hochladen" buttons on /upload, German strings that may iterate).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Two bugs surfaced while running the new E2E suite, plus a small test hook:
- jwt.rs: add a per-token `jti: Uuid` claim. Without it, two `create_token`
calls in the same wall-clock second for the same (sub, role, event_id)
produced identical JWT bytes — and identical sha256(token) hashes —
which then collided on `session.token_hash UNIQUE` with a 500. Manifests
in real use when an admin clicks "Anmelden" twice fast.
- auth/handlers.rs: reject display names containing 0x00. Postgres rejects
NUL in TEXT columns with `invalid byte sequence for encoding "UTF8"` and
the request leaks back as a 500. Now returns 400 with a clean message.
- handlers/test_admin.rs + main.rs: new POST /api/v1/admin/__truncate route,
compiled in always but only **registered** when EVENTSNAP_TEST_MODE=1 is
set on startup. Truncates every event-scoped table, reseeds config from
migration defaults, wipes media on disk, and clears the in-memory rate
limiter. RequireAdmin-gated so it's not anonymous even in test mode. In
production builds (no env var) the route returns 404 — verified by the
startup log message.
- services/rate_limiter.rs: add `clear()` so the truncate handler can wipe
the in-memory window map between tests.
- Dockerfile: bump rust:1.87 → rust:1.88 (current dep tree needs it) and
COPY ./migrations into the build context so the `sqlx::migrate!()` macro
can resolve at compile time.

A bundle of v0.16 platform work landing on top of the SvelteKit viewer.
Brings in 7 commits across docs, backend infra + features, frontend
plumbing, the live diashow, all UI surfaces (with dark mode), and a
viewer rebuild.
Headline features:
- Live diashow with two-queue policy (live drains first, shuffle as
fallback) and pluggable transitions. Design: docs/CONCEPT_DIASHOW.md.
- Dark mode: 'system' / 'light' / 'dark' preference, picked in the
onboarding step + the Account page, applied via Tailwind v4
class-based dark variant with FOUC guard.
- Host/Admin PIN reset with one-time PIN modal; admin may also reset
host PINs. Hosts may demote other hosts.
- Per-user dynamic storage quota enforced on upload + live widget in
My Account and on the upload screen. Toggleable per-area.
- All rate-limits + quotas individually toggleable from the admin
config UI (rendered as switches + a privacy_note textarea).
- Mobile-first gestures: long-press → context sheet, double-tap to
like with heart-burst. Buttons stay as desktop equivalents.
- Data mode (Saver vs Original) per device, applied across feed,
lightbox, and diashow.
- Per-event Datenschutzhinweis admin-editable, live-refreshed on all
clients via SSE event-updated.
- /api/v1/upload/{id}/original endpoint, /me/context + /me/quota.
Hardening (latent issues from the long-term review):
- Startup recovery for stuck compression / export jobs after a crash.
- Hourly cleanup of expired sessions + cold rate-limiter HashMap keys.
- ffmpeg 120s timeout with kill_on_drop (no more permit leaks).
- Per-user IndexedDB upload queue (no more cross-user leak on shared
devices); IDB schema bumped to v2.
- SSE reconnect uses exponential backoff (no more retry storm).
- PIN lockout no longer escalates — attempts reset when the cooldown
expires.
- soft_delete is now transactional and decrements total_upload_bytes
so quotas don't drift.
- pin-reset SSE handler filters by user_id so a host resetting Anna's
PIN doesn't clear Bob's cached PIN.
- Privacy note shown preformatted; admin-editable, ≤16 KiB cap.
Docs:
- New: FEATURES.md (role matrix), USER_JOURNEYS.md, IDEAS.md,
CONCEPT_DIASHOW.md, backend/migrations/README.md,
frontend/src/lib/README.md.
- Refresh: PROJECT.md, README.md, TEST_GUIDE.md, the two existing
CONCEPT_*.md banners.
Replaces the old single-file minijinja HTML export with a polished
read-only SvelteKit app shipped alongside the event data. Same
components and Tailwind tokens as the live app — visual parity with
zero divergence risk.
Brings in 4 commits:
4f96653 feat: add export-viewer SvelteKit static app
2fd66a8 chore: build and commit export-viewer static output
ffc926b feat: replace HTML export with SvelteKit viewer
1685bf1 fix: update export page guide text for new viewer
Design: docs/CONCEPT_HTML_VIEWER.md
Pre-built output regenerated after frontend/export-viewer/src/app.css
started importing ../../src/tailwind-theme.css. Output now picks up the
same @theme tokens and class-driven dark variant as the live app, so
future viewer-side use of bg-primary / dark: utilities will resolve
identically to the main bundle.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
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>
- handlers/me.rs (new): GET /api/v1/me/context (profile + role + privacy_note
+ quota toggle state, fetched once on app bootstrap) and GET /api/v1/me/quota
(live used / limit / active uploaders / free disk).
- handlers/upload.rs:
- quota enforcement via the dynamic formula
floor((free_disk * tolerance) / max(active_uploaders, 1)),
gated by quota_enabled + storage_quota_enabled toggles
- new GET /api/v1/upload/{id}/original — unauthed by design
(matches /media/previews/* — URL is the secret) so it works as
<img src> / <video src> / window.open
- rate-limit toggle wiring (rate_limits_enabled + upload_rate_enabled)
- handlers/host.rs:
- POST /api/v1/host/users/{id}/pin-reset — Host may reset guest PINs,
Admin may reset guest + host PINs (never another admin or self).
Returns the freshly-generated plaintext PIN once; emits a global
pin-reset SSE so the affected user's device can clear its localStorage.
- set_role guard expanded so hosts can demote other hosts (not self,
never admins) — backend match for the doc'd permission model.
- handlers/admin.rs: ALLOWED_KEYS split into NUMERIC_KEYS / BOOL_KEYS /
TEXT_KEYS with per-kind validation; saving privacy_note broadcasts an
event-updated SSE so other clients refresh live.
- handlers/feed.rs, handlers/admin.rs (export), auth/handlers.rs:
rate-limit toggle wiring at every limiter call site.
- auth/handlers.rs: when an expired PIN lockout is detected on /recover,
reset failed_pin_attempts to zero before the bcrypt check — without
this every wrong PIN re-locked the user after the cooldown.
- main.rs: wire startup_recovery + spawn_periodic_tasks, register the
new /me/context, /me/quota, /upload/{id}/original, and
/host/users/{id}/pin-reset routes.

Foundations for the v0.16 features. No new endpoints here — those land in
the next commit on top of these.
- migrations 008 + 009: commit the load-bearing compression_status column
that was uncommitted on disk; add 009_feature_toggles seeding the master
+ per-endpoint rate-limit switches, the master + per-area quota switches,
and the admin-editable privacy_note.
- services/config.rs (new): get_str / get_i64 / get_usize / get_f64 / get_bool
consolidating the scattered helpers that lived in three handlers.
- services/maintenance.rs (new):
- startup_recovery() — resets compression_status='processing' and
export_job.status='running' rows orphaned by a previous crashed
instance, so users never see permanent "Wird vorbereitet…" spinners.
- spawn_periodic_tasks() — hourly cleanup of expired sessions (rows
were never pruned) + rate-limiter HashMap pruning (windows kept one
entry per IP forever).
- services/jobs.rs (new sketch): BackgroundJob trait + JobContext for
future jobs to plug into the same progress + SSE pipeline as
compression/export. Not wired yet — codifies the convention.
- services/compression.rs: 120s hard timeout + kill_on_drop on ffmpeg
so a malformed video can't hang and leak a worker semaphore permit.
- services/rate_limiter.rs: new prune() called from the periodic task.
- state.rs: SseEvent::new() constructor so event-type strings stay
consistent instead of being typed inline at every emit site.
- models/user.rs: UserRole::as_str() for /me/context serialization.
- models/upload.rs: soft_delete() now runs in a transaction and
decrements the uploader's total_upload_bytes (GREATEST(0, …) guard) —
fixes a quota drift where deleting reclaimed no quota.
- Cargo.toml + Cargo.lock: add `infer = "0.15"` (multipart MIME sniffing
used by the upload handler).

- 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).

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.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Pre-built SvelteKit static output for embedding into HTML export ZIPs.
When viewer source changes, rebuild with `npm run build` in
frontend/export-viewer/ and re-commit this directory.

Standalone SvelteKit project at frontend/export-viewer/ using
adapter-static. Replicates the live feed experience as a read-only
offline gallery: list/grid views, search with autocomplete, hashtag
filtering, lightbox with swipe navigation and comments.
Built output goes to backend/static/export-viewer/ for embedding
into the HTML export ZIP.

Feed: shows star icon (→ /host) for host/admin, shield icon (→ /admin)
for admin only, alongside the existing account icon.
Host: shows shield icon (→ /admin) for admin only next to "Zur Galerie".
Admin: replaces "Host-Dashboard" text link with star icon (→ /host).

- Enable minijinja 'json' feature so the tojson filter is available in
the Memories.html template (was causing 'unknown filter' render error)
- Replace window.location.href downloads with fetch+blob so the
Authorization header is sent (window.location.href caused 401)

Password form at /admin/login that calls POST /api/v1/admin/login and
redirects to /admin on success. Admin dashboard now redirects to
/admin/login instead of /join when unauthenticated. Test guide updated.

Backend: migration 007 adds a case-insensitive unique index on user names
per event. join endpoint returns 409 conflict when the name is taken.
find_by_event_and_name uses LOWER() for case-insensitive recovery.
Frontend: join page handles 409 with a name-taken view — amber warning,
name-choice tips, inline PIN recovery form, and "Anderen Namen wählen"
button. Test guide updated with Steps 8 and 9.

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.

- Disable Axum's 2 MB default body limit on the upload route so large
photos/videos are accepted without HTTP 400
- Serialize UserRole as lowercase in JWT so the frontend role checks
('guest'/'host'/'admin') match correctly
- Drain multipart body before returning early upload errors (rate-limit,
ban, event-lock) to keep the HTTP keep-alive connection clean and
prevent cascading Netzwerkfehler / empty-500 responses
- Add TraceLayer for request logging and Vite dev proxy config

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 sliding-window in-memory RateLimiter service (Arc<Mutex<HashMap>>)
with per-IP and per-user-id limits on all public endpoint classes:
- POST /api/v1/join: 5/min per IP
- GET /api/v1/feed: configurable per IP (feed_rate_per_min, default 60)
- POST /api/v1/upload: configurable per user (upload_rate_per_hour, default 10)
- GET /api/v1/export/zip|html: configurable per IP (export_rate_per_day, default 3)
Limits are hot-reloadable via the config table. All 429 responses use
German error messages. Client IP is read from X-Forwarded-For (Caddy).

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

Add Admin Dashboard at /admin for server configuration, disk usage
monitoring, and export job status, plus a public export/status endpoint.
Backend — new /api/v1/admin/* endpoints (RequireAdmin auth):
- GET /admin/stats → user/upload/comment counts + disk usage
- GET /admin/config → all config key/value pairs
- PATCH /admin/config → update any subset of config keys; validates
key whitelist and numeric values
- GET /admin/export/jobs → export_job rows for the event
Backend — public (AuthUser) endpoint:
- GET /export/status → released flag + zip/html job status/progress
Frontend — /admin page:
- Stats grid: guest count, upload count, comment count
- Disk usage bar with GB/MB formatting; red ≥ 90%, amber ≥ 75%
- Config form: labelled numeric inputs for all eight config keys,
sends only changed values on save
- Export jobs list: type label, status badge, progress bar for running jobs,
error message if failed; manual refresh button

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
