H1: auth extractor re-reads the live user row — trusts the DB role (not the
JWT claim) and rejects banned users mid-session. e2e proves a demoted
host loses powers and a banned host is locked out and can't self-unban.
H2: client_ip takes the right-most XFF hop (the one Caddy appends); spoofed
left-most entries are ignored, restoring IP-based throttles.
H3: Caddy excludes /api/v1/stream from `encode` so SSE isn't buffered.
H4: upload — quota increment + row insert + hashtag links now one txn.
H5: feed keyset pagination tiebroken on (created_at, id) + composite index
(migration 010); feed_delta bounded with LIMIT.
H7: LightboxModal keys its comment load off upload.id, ending the
SSE-driven refetch storm.
H8: CSP via SvelteKit kit.csp (svelte.config.js) hardens the localStorage
token model against injection.
Migration 010 also adds the latent comment/comment_hashtag indexes.

The suite was almost entirely e2e; pure logic had no direct coverage. Add fast,
DB-free unit tests on both sides.
Backend (cargo test — inline #[cfg(test)] modules):
- rate_limiter: allow-up-to-max-then-block, per-key independence, sliding-window
expiry, retry-after bounds, clear(), and client_ip X-Forwarded-For parsing
(first entry / whitespace-trim / fallback).
- sse_tickets: single-use consume (replay → None), unknown ticket, uniqueness +
hex shape, prune keeps fresh tickets, and an expired ticket (injected past-TTL
entry) consumes to None.
- hashtag: fill the boundary gaps the 3 existing tests missed — stop-at-non-word,
the 40-char cap (drops, doesn't truncate), no-dedup contract, and the German
umlaut truncation limitation (pinned so a future Unicode fix is deliberate).
Frontend (Vitest — new, standalone config that stubs $app/environment so
server-safe module paths import cleanly under node):
- avatar: avatarPalette (neutral for empty, deterministic, real palette entry) and
initials (?, single word, two words, whitespace collapse).
- data-mode-store: pickMediaUrl across original/saver modes and the
preview→thumbnail→original fallback chain.
- `npm run test:unit` script added.
Backend: 20 passing. Frontend: 11 passing. svelte-check: 0 errors.

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).

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).

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.

- 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
