5f702f2b40 fix(audit-5): export disk preflight, media reclaim, low-disk warning, restore docs
Fifth round, all storage. The keepsake could not fit on the documented hardware
and failed halfway through a multi-GB write, leaving the deliverable stuck; the
quota had stopped bounding the disk; and the backup had no restore procedure.

Squashed from 6 commits, original messages preserved below.

──────── fix(export): refuse an export that cannot fit, and stop peaking at two generations

Nothing in export.rs ever asked whether the keepsake would fit. Both archives write
their media `Compression::Stored`, so each is essentially a byte-for-byte second copy
of the originals -- Gallery.zip always, and Memories.zip for every video and every
image at or under 5 MB. On the documented CX33 (80 GB, all three volumes on one
filesystem) the upload quota's fixed point leaves ~40 GB free, and a release spawns
BOTH halves concurrently against it.

The failure is not "the export failed", it is "the deliverable is stuck":

  1. ENOSPC lands partway through a multi-GB write.
  2. The epoch has already moved, so the job row is `failed` at the CURRENT
     generation and readiness (epoch = event.export_epoch AND status = 'done') is
     false -- GET /export/zip 404s.
  3. The last good archive sits on disk, unreferenced and unreachable.
  4. POST /host/export/rebuild, the only escape, re-arms the same doomed write.

Three changes.

Reclaim before building. `prune_stale_export_files` ran only after the new archive
was written, renamed and finalised. That reads as durability but buys nothing: the
moment `invalidate_and_arm` bumps the epoch the old archive is ALREADY unreachable,
so keeping it reserves gigabytes for a download nobody can perform -- and for a
takedown it is content someone explicitly asked to have removed. Peak usage is now
one generation. Narrower than the post-finalize prune on purpose: final archives
only, never a `.tmp` or a `viewer_tmp_` dir, since a superseded worker can still be
streaming into those and at build START is far more likely to be alive.

Preflight the space. SUM(original_size_bytes) over exactly `query_uploads`'
visibility filter, +10% for ZIP overhead, multiplied by the number of armed jobs --
without that multiplier each of the two concurrent halves independently sees "it
fits" and together they don't. Runs AFTER claim_job, not before as reported: bailing
before the claim leaves the row `pending` with no worker and no error, the
spinner-forever state `mark_failed`'s status guard exists to prevent. Fails open when
the mount can't be read, exactly as the upload quota does.

Show the host the reason. /export/status returned {status, progress_pct} and nothing
else, so the host dashboard could only render "fehlgeschlagen" next to the retry
button. The message was written to the row and surfaced solely in the ADMIN job list
-- a different screen, possibly a different person. It now travels with the status,
and only on a failure, so a message left on a since-succeeded row can't appear beside
a green "ist bereit".

Tests: 10 unit (the u128 clamp caught a real bug in the first draft -- saturating_mul
then /100 turns an overflow into a number ~100x too small, the one direction that
authorises the write being guarded against; the carried-forward archive must survive
its own older epoch in the filename), 4 DB-backed (the estimate is asserted against
the row set the archive actually contains, not against a restatement of the WHERE
clause, so the two queries cannot drift), 3 e2e over the four-hop plumbing.

──────── fix(maintenance): reclaim the media of deliberately deleted uploads

The quota stopped bounding the disk. `soft_delete_in_event` stamps `deleted_at` and
refunds `total_upload_bytes`, but nothing ever removed the bytes, and the hourly
sweep reached only `compression_status = 'failed'`. Upload 500 MB, delete, quota back
to zero, upload another 500 MB. Not an attack -- a guest curating their camera roll,
which is what people do. The host then sees guests hitting "Du hast dein Upload-Limit
erreicht" while the admin widget shows a disk full of files no upload row points at,
and the quota message is actively misleading because the space really is gone, just
not to anyone the accounting can name.

Two retention windows, because the two deletes mean different things. A compression
failure keeps its 14 days: the guest didn't ask for it and may not be able to retake
the photo. A deliberate removal gets 24 hours -- 14 days outlives the whole event, so
a deliberate delete would never reclaim anything while it mattered, and a day still
covers a mis-tap.

Wider than reported: ALL FOUR paths are reclaimed, not just the original. Preview,
display and thumbnail are each a separate file, none counted in
`original_size_bytes`, and nothing ever removed them either. That was invisible while
the sweep only saw failed compressions (which produce no derivatives) and becomes
three leaked files per upload the moment it reaches a successful one. A row is
re-selected until every path is cleared, and the columns are cleared only once every
file for that upload is gone -- clearing after a partial success would strand the
survivors in exactly the unowned state this drains.

`backfill_stale_derivatives` selects on `display_path IS NULL AND preview_path IS NOT
NULL`, which is close enough to the post-sweep state to be worth pinning: it is
guarded on `deleted_at IS NULL`, so it cannot re-decode an original that is no longer
on disk. Covered.

Residual, deliberately: within the 24h window the bytes are still spent and still
unaccounted, so delete-and-re-upload through an eight-hour event can outrun the
sweep. Bounding that means holding the quota until the file is reclaimed rather than
refunding at `deleted_at`. The low-disk warning is the net under it.

Tests: 6 DB-backed, replacing 3. The one asserting an owner-deleted upload IS
reclaimed is the exact inverse of what this file used to assert.

──────── feat(host): warn about low disk before it becomes unrecoverable

Storage visibility existed in exactly one place: a passive Speicherauslastung widget
on the ADMIN dashboard. A host who isn't the admin had no view of it, and nothing
warned anyone. README carried "Low-disk alert (< 10 GB free)" under Planned since v1.

Two things make this a safety net rather than a nice-to-have. postgres_data,
media_data and exports_data are all Docker named volumes on ONE filesystem, so
running out doesn't degrade a subsystem -- Postgres stops being able to write and the
whole event goes down. And the keepsake needs room for two gallery-sized archives,
which the export preflight can only ever refuse AFTER the release, when the event is
over and every remedy is harder.

So the threshold is not a fixed number alone. It fires on the 10 GB floor the README
always named, OR on "you could not build the keepsake right now" -- the trigger a
host can still act on, computed with the same arithmetic the preflight uses. Unknown
free space is NOT low: it fails open like the upload quota and the preflight do,
because a banner that cries wolf on an unreadable mount is a banner nobody reads.

Carried on GET /host/event, which the dashboard already fetches on load and on every
reload -- no new endpoint, no new poll. Rendered above everything else including the
PIN-reset queue, and it names the consequence (the event, not just the download)
rather than only the number.

Also fixes the host page's formatBytes, which topped out at MB: 30 GB free would have
rendered as "30720.0 MB", and a guest with 2 GB of uploads was already being shown
that way in the user list.

Tests: 5 unit on the threshold (including that plenty of free space is still low when
the keepsake wouldn't fit -- the case a fixed threshold misses entirely), 3 e2e.
The e2e drives it through `original_size_bytes` rather than a genuinely full disk:
the estimate is pure SQL over that column, so overstating one row moves the
accounting without touching a byte on disk.

──────── docs: add a restore procedure, fix the backup cadence, and correct quota_tolerance

Four things, all found by the same question: what does an operator standing at the
venue actually need?

A RESTORE PROCEDURE. There was none anywhere, and a backup you have never restored
isn't a backup. Two hazards worth writing down: media must be extracted preserving
ownership (the app runs as uid 100 / gid 101, and a root-owned restore makes every
upload fail with EACCES surfacing as a generic 500), and the app must be STOPPED
first, because migrations run on boot and a live pool will fight the restore.

Both the backup and the restore commands were run against the real stack before being
written down, which caught two that would have failed:

  - The plain `pg_dump` did not restore: `psql` aborted on `ERROR: schema
    "_sqlx_test" already exists`. pg_dump emits no DROPs without --clean --if-exists,
    so the documented dump could only ever be restored into an empty database. Fixed
    at the source (the dump is now self-cleaning) and verified end to end: 16 tables
    back, exit 0.
  - `--same-owner` does not exist in BusyBox tar, which is what `alpine` ships, so
    the extract aborted before unpacking anything. `--numeric-owner` plus the
    explicit chown, verified to land 100:101.

BACKUP CADENCE. "Weekly offsite" is the wrong shape when every irreplaceable byte is
created in one eight-hour window and nobody can retake a wedding. The backup that
matters runs that night, and again after the release so the keepsake is captured.
Also: take the DB dump and the media tarball back to back, or you get rows pointing
at files the dump doesn't know about.

quota_tolerance WAS DOCUMENTED AS SOMETHING IT ISN'T. .env.example called it "fraction
of disk that triggers the low-storage warning". It is the multiplier in
`floor(free_disk * tolerance / active_uploaders)` -- so an operator who wants "warn me
later" and sets 0.95 is actually authorising guests to fill 95% of the disk, moving
the fixed point from 43% to ~49% and eating the export headroom. The admin UI labelled
it "Toleranz (0-1)" with no explanation at all, which invites exactly that reading;
it is now "Speicher-Anteil für Gäste" with the formula in the hint. Wrong docs on a
tuning knob are worse than no docs.

SIZING. New section with the arithmetic: three volumes on one filesystem, the quota
fixed point at tolerance/(1+tolerance), and the fact the 80 GB baseline does not cover
the keepsake -- both archives are built concurrently and each is roughly a second copy
of every original. Provision ~3x expected media, or give exports its own volume.

Also ticks the low-disk alert off the roadmap, since it now exists.

──────── chore: raise the db memory limit and rate-limit social writes

Two smaller operational items.

POSTGRES 512M -> 1G. DATABASE_MAX_CONNECTIONS is 30 for a ~100-guest event (feed
polling + SSE + uploads at once), and 30 backends plus Postgres 16's default
shared_buffers leaves very little headroom at 512M. An OOM here doesn't degrade one
feature -- every request path touches the database, so it takes the event down.
Memory is the cheaper knob than shrinking the pool back and reintroducing the
queueing it was raised to fix. .env.example now names the pairing explicitly, the way
it already does for COMPRESSION_WORKER_CONCURRENCY.

SOCIAL WRITES WERE UNTHROTTLED. toggle_like, add_comment and delete_comment were the
only mutating endpoints in the app with no limit at all -- upload, join, recover,
export and admin login all carry one. Asymmetric coverage rather than a deliberate
decision.

Low severity, and honestly so: a like fans an SSE broadcast to every client, but the
export regeneration a comment deletion triggers is contained (REGEN_DEBOUNCE 20s,
workers born with their epoch, superseded ones inert). So the ceiling is 120/min --
far above anything a real guest produces. This bounds a script, not an enthusiastic
double-tapper.

ONE bucket across all three actions: separate buckets would let a caller triple the
aggregate write rate by alternating between them. Keyed per USER, matching the feed
and upload limits -- at a venue every guest is behind one NAT, and an IP key is what
made the /join and /feed limits turn guests away in the first place.

Migration 020 seeds both keys, and both are wired into the admin allowlist, the
config UI and the e2e reseed -- the step two earlier per-area toggles missed, which
left switches that existed in code and could never be flipped.

Tests: 4 e2e, including that the shared bucket really is shared (the part most likely
to be lost in a refactor) and that one guest hitting the ceiling doesn't block
another behind the same IP.

──────── fix(e2e): stop the video poster assertion racing the ffmpeg thumbnail

Pre-existing, and it fired for real during the full-suite run on a cold stack.

The lightbox binds `poster={upload.thumbnail_url ?? undefined}`, so the attribute is
absent until compression produces the thumbnail. This test asserted on it immediately
after seeding, never waiting for the worker -- unlike the Range test further down the
same file, which does poll. Against a warm stack the worker usually wins; against a
freshly rebuilt one (`stack:down -v`, cold ffmpeg) it doesn't.

That is the worst possible time for a false failure: the first run after a rebuild is
exactly when you are trying to establish whether a change broke something. Poll for
`compression_status = 'done'` before the poster assertion. The `src` assertion needs
no wait and keeps none.

Verified with --repeat-each=3.

b601c062bd fix(audit-2): video playback, role identity, keepsake EXIF, recover ceiling, WebKit CI
Second round: the two regressions the first round introduced, the remaining
gaps it left, and the CI change that makes the iOS guarantees actually gate a
change rather than being asserted.

Squashed from 9 commits, original messages preserved below.

──────── docs(deploy): document the update path — `up -d` alone ships nothing

The README only ever described a fresh install. There was no update section
anywhere, and `--build` appeared nowhere in the docs.

That matters because `app` and `frontend` are `build:` services with no published
image tag, and Compose has no source-change detection: if an image by that name
exists it is reused. So the natural `git pull && docker compose up -d` reports
"Container app-1 Running", rebuilds nothing, and exits 0. A deploy that shipped
none of the new code is indistinguishable from a successful one — which is how
eleven merged fixes can sit in the repo and never reach the box.

Verified both halves against a real stack rather than asserting them: with a
source change staged, `up -d` left the image ID untouched; `up -d --build`
produced a new image ID and a healthy /health.

Adds an "Updating an existing deployment" section covering backup-before-migrate,
pull, rebuild, health check, and an image-ID comparison to prove a build actually
happened. Also spells out the rollback trap: migrations run on boot and are not
undone by checking out an older commit, so rolling back code without restoring
the snapshot leaves the schema ahead of the binary and the app refusing to start.

──────── fix(video): play the actual video, and answer Range requests

Every video in the app was unplayable. Two independent defects, either one
sufficient on its own, and nothing in the suite covered either — no test
anywhere played media or asserted a `<video>` src.

1. The lightbox handed `<video>` a JPEG.

`pickMediaUrl` is mime-agnostic, and compression only ever produces a THUMBNAIL
for a video (one `ffmpeg -vframes 1` frame) — no preview, no display. So in the
DEFAULT saver mode the element's src resolved to `/api/v1/upload/{id}/thumbnail`,
served as `image/jpeg` with `nosniff` so the browser can't even sniff its way
out. Chromium reports DEMUXER_ERROR_COULD_NOT_OPEN.

Fixed in the lightbox rather than in `pickMediaUrl`: FeedListCard shares that
helper and legitimately wants the thumbnail for its `<img>` poster, so a central
mime branch would break the feed. This mirrors the rule the diashow already
applies ("videos play the original file directly"). Added `preload="none"` so
saver-mode guests on cellular still fetch nothing until they press play — there
is no smaller video derivative to offer them — plus `playsinline`, without which
iOS hijacks playback into fullscreen.

2. `stream_media_file` ignored Range entirely.

It took no request headers, so it could not see `Range`; it always returned 200
with the whole body and never sent Accept-Ranges or Content-Range. iOS Safari
opens every `<video>` with a `Range: bytes=0-1` probe and abandons the load
without a 206 — so video failed on the app's primary platform even in `original`
mode, where the src was already correct.

Adds single-range support (`bytes=N-`, `bytes=N-M`, `bytes=-S`) with 206 +
Content-Range, 416 + `bytes */len` past EOF, and Accept-Ranges advertised on
every response. Anything it won't handle — multi-range, non-bytes units, garbage
— falls back to a full 200, which RFC 9110 explicitly permits and which is safer
than guessing. All four media routes share the helper, so seeking works
uniformly.

`get_original` now serves `inline` instead of `attachment`. An attachment
disposition is hostile to a `<video>` element, and this route is the only source
of playable video bytes; it also matches what the UI promises, since the action
is labelled "Original anzeigen" — view, not download. `no-store` is deliberately
kept so a takedown still revokes access promptly; ranges work fine under it, the
client just re-fetches.

Tests: 11 unit tests pin the parser (the iOS `bytes=0-1` probe, inclusive ends,
suffix ranges, clamping past EOF, 416 vs 200, malformed fallbacks). A new
03-feed/video-playback spec asserts the src is the original and not the
thumbnail, that the browser accepts the bytes as media (readyState > 0, no
MediaError), that no video bytes are delivered before play, and that Range
returns the correct 206 slices and a 416 past EOF — verified on both Chromium
and WebKit.

The "not downloaded before play" test asserts no *delivered body* rather than no
request: WebKit opens a connection for a preload="none" video and immediately
aborts it (GET, no Range, status 0, nothing transferred) while Chromium issues
nothing at all. The portable guarantee is that no response carrying bytes
completes.

──────── fix(auth): bind the role store to the identity, not to the tab

The role store I added in the moderation work is a module-level singleton seeded
ONCE at import. `goto()` is a client-side navigation, so leaving and re-joining in
the same tab re-imports no module and re-runs no onMount — the previous user's
role simply stayed resident. Nothing reset it: not join, recover, admin login,
"Event verlassen", `clearAuth`, nor the api.ts 401 auto-clear.

So a host who left, followed by a guest joining on the same phone, left that guest
with `isStaff === true` and a "🚫 Beitrag entfernen" action on other people's
photos. The backend 403s the delete, so this was a false affordance rather than a
privilege escalation — but `/feed` never fetched `/me/context`, so unlike every
other route it never self-corrected either. It survived until a hard reload.

The mirror case was equally broken and easier to overlook: a guest who recovered
into a host account got NO host affordances.

`clearAuth` already had a hook registry for exactly this shape of problem, with a
comment explaining it exists to avoid circular imports. Add the missing mirror,
`onSetAuth`, fired by both `setAuth` and `setAdminAuth` after the new token is
resident, and have the role store register on both sides: clear to null on
logout, re-seed from the new token on login. That also gives
`syncRoleFromToken` — dead code with zero callers since I introduced it — its
intended purpose.

Seeding from the claim fixes the reported bug, but the claim is frozen for the
token's 30-day life, so a promotion or demotion still wouldn't reach the feed.
`/feed` now calls the existing `refreshEventState()` on mount, which fetches
`/me/context` and applies both the authoritative role and the lock/release state
in one request. The feed is the one route gating a destructive action on the role,
so it should not be the only route running on a stale claim.

Tests: 04-host/role-identity-reset drives the real flows. The first asserts the
host DOES see the action before asserting the newcomer does not — a negative
assertion alone would pass against a build that shipped no moderation at all. The
second covers the mirror, promoting a guest server-side while their resident token
still claims `role: guest`, so a fix that only cleared the role would fail it.

──────── fix(compression): reclaim failed originals instead of leaking them

Round 1 stopped the compression worker deleting an upload's original on failure —
a transient ENOSPC or a codec panic must never destroy the only copy of a photo a
guest cannot retake. But it left `Upload::soft_delete`'s quota refund in place, so
the bytes stayed on disk while the uploader was charged nothing for them.

That is worse than it first looks. The row is soft-deleted, so the file is
invisible and unowned; a guest hitting a reproducible codec failure can accumulate
orphans indefinitely at zero personal cost. And `active_uploaders` counts only
users with non-deleted uploads, so dropping out of that count RAISES everyone's
per-user ceiling — the leak loosens the very quota meant to contain it.

Keep the refund: the uploader didn't cause the failure and shouldn't silently lose
quota to it. Bound the leak instead, with an hourly sweep alongside the existing
session cleanup in `spawn_periodic_tasks`, reclaiming failed originals older than
14 days — comfortably longer than any single event, so an operator investigating a
failed upload still has the file.

The selection predicate is the entire safety argument, so it is deliberately
narrow: `compression_status = 'failed'` AND soft-deleted AND past the window AND
`original_path <> ''`. That is exactly the state the give-up path leaves behind,
and it cannot reach a live upload, an owner-deleted one, or a failure still inside
its recovery window. `original_path` is cleared after a successful reclaim, which
makes the sweep idempotent — otherwise a row whose file is already gone is
re-selected on every tick forever. The row itself is kept as the audit trail.

Tests reproduce the selection verbatim (same pattern as upload_concurrency) and
assert it against five near-misses that must survive, both sides of the retention
boundary, and the idempotence property.

Also fixes two comments in export.rs still claiming "the compression worker
hard-deletes an original when its transcode fails" — no longer true, and the
defensive handling they justify is now justified by this sweep and by ordinary
deletes instead.

──────── fix(export): apply EXIF orientation in the keepsake too

Round 1 fixed EXIF orientation in the compression worker, which corrected the live
app — feed preview and diashow display. The export worker was missed, and it does
not reuse those derivatives: it re-decodes the originals itself with `image::open`,
which ignores the orientation tag, then re-encodes to JPEG, which drops the tag —
so the viewer has no way to recover it.

The damage was oddly shaped, which is exactly why it reads as a viewer bug:

  Gallery.zip originals              correct  (byte-copied, EXIF intact)
  Memories viewer grid thumbnails    SIDEWAYS (always)
  Memories viewer full image >5 MB   SIDEWAYS (re-encoded at 2000px)
  Memories viewer full image ≤5 MB   correct  (streamed byte-for-byte)

So in the keepsake people actually keep, every portrait photo in the grid was on
its side, and clicking through silently "fixed" small photos but not large ones.

Rather than paste the decoder dance a third time, extract `services::imaging::
decode_oriented` and route both workers through it, so there is exactly one way to
turn a file on disk into a DynamicImage. It carries a second invariant that had
also drifted: `image::open` applies NO decode limits, so the export path was
decoding arbitrary user-supplied images unbounded — the decompression-bomb cap
existed only in the compression worker. Both now come as a pair, which is the
point of having one function.

Not done: switching export to consume the existing `display` derivative. It would
fix orientation and drop a redundant full-resolution decode per photo, but it
would also replace the pristine ≤5 MB originals in the keepsake with 2048px
re-encodes — a real quality regression in the one artefact people keep forever.

Test uploads the round-1 fixture (40x20 landscape tagged Orientation=6), runs a
real export, pulls the thumbnail out of Memories.zip and asserts it came back
portrait — with a sanity check that the source really is stored landscape, so the
test can't pass against a pipeline that does nothing.

──────── fix(recover): cap name cycling, and stop bcrypt blocking the runtime

Round 1 gave /join a per-IP ceiling and left /recover with only its
`recover:{ip}:{name}` bucket. That key is right for the job it was written for —
stopping someone who knows a display name (they're listed on the feed) from
burning the victim's 3-strike PIN counter and locking them out on repeat. But the
name is ATTACKER-CHOSEN, so cycling names mints a fresh 5-attempt bucket every
time and the per-IP cost is unbounded.

What sits behind that limiter makes it worse than a normal flood: every call runs
a cost-12 bcrypt verify, including an UNCONDITIONAL throwaway verify for names
that don't exist — added deliberately to close a timing oracle. So an unknown name
is the single cheapest way to make the server do ~200ms of hashing.

Adds `recover_ip_rate_per_min` (default 30, migration 019), checked BEFORE the
per-name bucket so a name generator can't walk past it. 30/min is far above any
real recovery attempt while capping a flood. The per-name bucket is untouched and
remains the anti-guessing control.

The second half matters as much as the first: bcrypt was running inline on the
async runtime everywhere. At cost 12 that pins a tokio worker thread for ~200ms,
and there is only one per core — so a login flood stalled every other request on
the box, including the feed. There was no spawn_blocking anywhere in the auth
module, despite SECURITY-BACKLOG claiming bcrypt had been offloaded.

Route all of it through `verify_password` / `hash_password` on the blocking pool.
That covers /recover, /admin/login, the host PIN reset, and — the one most likely
to bite at a real event — the PIN hash minted on every single /join. Saturating
the blocking pool degrades logins; saturating the worker threads degrades
everything.

Tests: cycling distinct names from one IP now hits the ceiling with a Retry-After,
and — the assertion that keeps the fix honest — repeated wrong PINs against ONE
name are still throttled with the ceiling set generously high, so the ceiling
added protection rather than replacing it.

──────── ci(e2e): run WebKit, so the iOS guarantees actually gate a PR

The workflow installed only Chromium and ran chromium-desktop + chromium-mobile.
iOS Safari is the app's stated primary user — a wedding guest opening a QR link —
and WebKit is the only engine in the matrix that reproduces two of its behaviours:

  - it enforces X-Frame-Options on the hidden download iframe, so a site-wide DENY
    makes the keepsake download silently do nothing. Blink hands attachments to
    the download manager before the frame check and never notices.
  - it abandons a <video> load unless its Range probe gets a 206.

Both of those shipped. Adding 06-export to the webkit project in the round-1 fix
bought nothing on a PR, because CI never ran that project at all — the regression
test written specifically to catch the blocker only ever executed locally.

Runs 71 tests (67 pass, 4 skip on the documented IndexedDB-blob harness
limitation) in ~1.5 minutes locally, using the exact command added here.

──────── chore(backend): satisfy cargo fmt

`checks.yml` runs `cargo fmt --check`, and it has been failing since the round-1
audit fixes: I gated those on `cargo build` and `cargo clippy` but never ran fmt,
so three files drifted then and eight more this round. Pure formatting — no
behaviour change; clippy stays at zero and all 70 backend tests still pass.

Worth noting for next time: clippy passing is not evidence fmt does.

──────── chore: satisfy prettier in frontend and e2e

`checks.yml` runs `npm run format:check` for both projects and both were failing.

- frontend/src/lib/ui-store.ts is mine, unformatted since the round-1 upload-queue
  badge fix — the same miss as the rustfmt one: I gated on svelte-check and eslint
  but never on format:check.
- e2e/loadtest/* and e2e/shots.mjs have been unformatted since 7758270 and are
  unrelated to the audit work. Fixed here because they block the same gate and the
  fix is mechanical; no behaviour change in either project.

Still red and deliberately NOT fixed here: `npm run lint` in the frontend reports
`svelte/prefer-svelte-reactivity` on routes/diashow/+page.svelte:208 (a mutable
`Set` where the rule wants `SvelteSet`), pre-existing since 5009590. That one is a
real reactivity change in code I have no test coverage for, so it belongs in its
own change rather than smuggled into a formatting commit.

bbdfae09a0 chore(e2e): add ESLint + Prettier; fix real findings; dedupe BASE
The Playwright suite had no linter and no formatter — only tsc. Add flat-config ESLint
(typescript-eslint, type-aware) and Prettier (2-space, matching the suite's style).

Rules keep the ones that catch real TEST bugs and drop the noise:
  - no-floating-promises KEPT — an un-awaited request/assertion can let a test end before it runs,
    passing vacuously. It caught one: the SSE reader loop in sse-listener is now explicitly `void`.
  - no-unused-vars KEPT — caught three dead bindings (an unused adminToken fixture arg, an unused
    `api` arg, an unused JPEG_MAGIC import), all removed.
  - no-explicit-any OFF — all test code; `any` is the honest type for an untyped res.json() body or
    a page.evaluate() return.
  - no-empty-pattern OFF — Playwright's dependency-free fixtures are `async ({}, use) => {}`.

Refactor: `const BASE = process.env.E2E_FRONTEND_URL ?? '...'` was redeclared verbatim in 23
files — extracted to helpers/env.ts and imported, so a port/scheme change is one edit not a sweep.

Then `prettier --write`. Verified: eslint clean, tsc clean, prettier clean, desktop suite 210
passed / 1 skipped. (One mobile spec flaked once under retries:0 — a pre-existing cross-test

641174717c fix(user-flow): close offline-queue, export, session, ban & realtime gaps
Some checks failed
E2E / Playwright E2E (chromium-desktop) (push) Failing after 6m52s
E2E / Cross-UA smoke matrix (push) Failing after 3m50s
Comprehensive user-flow review across guest/host/admin roles, then fixes with
e2e regression guards. Highlights:

- Offline upload queue auto-resumes on reconnect: network errors keep items
  pending (not error), 4xx are terminal (no infinite retry), quota exhaustion
  returns a distinct 413; queue cap + dedup.
- Export lifecycle: release atomically locks uploads; reopen invalidates and
  re-release regenerates the keepsake; workers claim their job atomically so a
  reopen->re-release can't corrupt the ZIP; startup re-spawns interrupted
  exports.
- Sessions slide on activity (no 30-day cliff); JWT expiry deferred to the
  revocable session row; sign-out-everywhere + revoke-on-PIN-reset.
- Ban always hides content (v_feed / find_visible_media / export filter
  is_banned) but stays a read-only ban per USER_JOURNEYS §10 — sessions are
  not revoked, read access + keepsake download preserved.
- Realtime: server-clock SSE delta cursor; event-closed/opened drive the UI
  live; feed_delta rate-limited; like returns {liked, like_count} to fix
  multi-device drift; lightbox live comments; diashow delta backfill.
- Forgotten-PIN in-app request flow; simultaneous same-name join returns 409;
  quota increment is transactional; operator floor.

Adds e2e/specs/10-flow-review/ (offline resume, export integrity, deterministic
anti-race guard) and updates existing specs for the new contracts.

dba4d3f932 fix(review-2): critical — repair comment posting + close export data leak
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).

74849c8d50 test: cover grid filter OR/AND (extract pure fn + unit + real e2e)
The two filter-search cases were test.fixme placeholders (expect(true).toBe(true)),
so the OR/AND chip rules were untested.

- Extract the grid-filter predicate from feed/+page.svelte into a pure
  filterUploads(uploads, filters) in $lib/feed-filter (behavior-preserving) and
  unit-test it (9 cases): tag OR, user OR, tag+user AND, AND-excludes-partial,
  case-insensitive caption match, null caption.
- Replace the e2e fixmes with real tests that seed known captions/uploaders, switch
  to grid view, activate chips via the search suggestions, and count grid tiles:
  OR widens 1→2, AND narrows 2→1.

Frontend unit: 27 passing. filter-search e2e: 3 passing.

b1e2e66305 test(e2e): address self-review follow-ups (dedup, XSS render guard, SSE hardening)
Follow-ups from the code review of the test-quality batches:

- Consolidate duplicated helpers into e2e/helpers/: seed.ts (seedUpload,
  seedComment, listComments, findFeedRow) and sse.ts (mintSseTicket, openStream,
  trackStreamOpens). Refactor authorization-deep, xss-injection, like-comment,
  sse-ticket-abuse, ddos, sse-realtime, multi-tab, and SseListener to use them —
  the upload/comment/ticket-flow contracts now live in one place each instead of
  being re-inlined across 3–7 specs.
- xss-injection display-name loop: it navigated to /feed (which renders uploader
  names, not the viewer's) so "nothing fired" passed vacuously — the payload was
  never rendered. Now navigate to /account (the actual sink) and add a render
  guard asserting the payload reached the DOM as escaped text before checking
  __xssFired.
- sse-realtime reconnect: snapshot the stream-open count AFTER backgrounding, so
  the "new connection" assertion is attributable to the foreground event and can't
  be satisfied by a spurious native/error reconnect before the toggle.
- recover-page: correct the comment (auto-submit is the onPinInput handler, not an
  $effect).

44 affected specs verified green.

564104ae23 test(e2e): robustness — stable locators, exact assertions, no fixed sleep
- ContextSheet: add data-testid="context-sheet". longpress tests targeted the
  open sheet via the `.translate-y-0` animation class (breaks on any animation
  refactor) — now target `[data-testid="context-sheet"][aria-modal="true"]`,
  which is stable and unambiguous vs. the centered LightboxModal (also aria-modal).
- toast-on-failure: the like button was `button.filter(hasText:/\d+/).first()`,
  which could match any digit-bearing button (e.g. the comment count) → use the
  stable aria-label "Gefällt mir".
- config stats: assert the exact user_count (4 = 3 seeded guests + admin) instead
  of `>= 3` — deterministic after the per-test truncate, catches under/overcount.
- offline-network 429 test: replace the fixed 3s waitForTimeout with a
  poll-until-the-retry-count-stabilizes (faster, and a real storm never stabilizes
  → the poll fails, which is the intended outcome).

Note: reviewed the "config restore not in try/finally" finding — it's a non-issue.
The truncate auto-fixture wipes+reseeds the whole config table (and clears the
rate limiter) before every test, so config state cannot leak between tests.

All affected specs verified green.

136417d6b4 test(e2e): make vacuous feed/SSE tests assert real behavior
Several tests ran green while asserting nothing. Replace them with real
assertions, and fix the SSE helper they depend on.

sse-listener: exchange the JWT for a single-use ticket (POST /stream/ticket) and
connect via ?ticket= — the helper still used the dead ?token= scheme, so every
SSE-based assertion would have silently failed to receive events.

like-comment:
- "like is idempotent" asserted nothing (void feed; void b) → now seeds a real
  upload and pins the like contract: counted once per user, toggles off on repeat
  (guards double-count), and a second user's like is counted independently.
- "comment → SSE to B" asserted length >= 0 (always true) → B now subscribes to
  the stream, A comments, and B must receive the new-comment event for that upload
  (comment_count === 1). ~30s due to reverse-proxy SSE buffering; timeout raised.

sse-realtime: only checked a nav link was visible → now counts EventSource opens
and asserts a fresh stream connection after hidden→visible (also fixes the sim,
which set visibilityState but not document.hidden, so the close never fired).

multi-tab "SSE delivers to both": only checked nav links → now asserts each tab
opens its own stream connection (delivery isn't asserted — it hinges on the ~30s
proxy buffering; connection establishment is the reliable, honest signal).

safe-area: delete the /join probe whose only assertion was Array.isArray(x) ===
true (always true); the real sheet-level env() check already exists below it.

All verified green against the live backend.

309c25bc06 feat(frontend): UX review followups — primitives + a11y/UX fixes across 4 passes
New shared primitives:
- Toaster + toast-store, ConfirmSheet, Modal, focusTrap action,
  pullToRefresh action, avatarPalette + initials helper, Skeleton,
  HeartBurst, haptics, export-status store with onClearAuth hook

Critical UX/a11y:
- Replaced window.confirm with branded ConfirmSheet
- Focus management + Escape on every modal (PIN, Lightbox,
  Onboarding, ContextSheet, data-mode sheet, leave-confirm,
  HTML guide, host/admin ban + PIN-display modals)
- Sheet backdrops are real buttons with aria-label
- Silent ApiError catches now surface via global Toaster

Major polish:
- Dark-mode parity on HashtagChips + avatars (shared palette)
- Conditional Export tab in BottomNav (badge dot when ZIP ready)
- Back chevrons on /recover (history-aware) and /export
- Upload composer discard confirmation when content is staged
- Camera segmented Photo/Video shutter
- PIN auto-submit on 4th digit, paste-flash-free (controlled input)
- Welcome-back toast on /feed after PIN recovery

Minor:
- Skeleton states on feed; pull-to-refresh with live drag indicator
- Haptics on like / capture / submit / PIN-copy / onboarding complete
- Comment 500-char counter; quota "Fast voll" / "Limit erreicht" labels
- Onboarding pip ≥24px tap targets; long-press hint step
- overscroll-behavior lock on <html> while feed mounted
- teardownExportStatus wired via onClearAuth (covers 401 + explicit logout)
- ConfirmSheet per-instance titleId; Modal requires titleId or ariaLabel

Tests (7 new Playwright specs):
- 01-auth/pin-auto-submit, 01-auth/back-chevron
- 03-feed/confirm-sheet-delete, 03-feed/toast-on-failure
- 09-mobile/focus-trap, 09-mobile/sheet-escape,
  09-mobile/upload-cancel-confirm

FOLLOWUPS.md captures the deferred AT inert containment work
with acceptance criteria + implementation sketches.

e42d8a92a1 feat(e2e): Playwright suite — 134 tests across 9 spec areas + UA matrix
Adds an end-to-end Playwright test suite under e2e/ that spins up an
isolated docker-compose stack (Postgres :55432, Caddy :3101, backend with
EVENTSNAP_TEST_MODE=1, SvelteKit adapter-node frontend) and exercises the
SvelteKit app against the real Rust backend.

Phase 1 — happy paths covering every documented USER_JOURNEYS.md flow:
  01-auth/      join, recover, admin login, leave event, PIN lockout
  02-upload/    gallery picker (API path), rate-limit + admin toggle
  03-feed/      like/comment SSE, filters, SSE reconnect on visibility
  04-host/      event lock API, ban/unban, promote
  05-admin/     config validation, foundational authz guards, stats
  06-export/    /export status + download stub
  __smoke/      cross-UA happy-path (runs on every UA project)

Phase 2 — adversarial + browser chaos:
  07-adversarial/  XSS payloads (6 × display name path), SQLi shapes,
                   length / encoding / RTL override / NUL byte;
                   file-upload boundaries (ELF body claimed as JPEG,
                   oversize vs max_image_size_mb, zero-byte, NUL
                   filename, path-traversal, SVG-with-script);
                   JWT alg:none, signature/payload tamper, expired
                   session, PIN brute-force (serial + parallel),
                   admin password brute-force; deep authz (cross-user
                   delete, banned user across like/comment/feed-read,
                   host→admin escalation); small-scale DDoS (20× /join,
                   10MB comment body, 10 concurrent SSE).
  08-browser-chaos/ localStorage / sessionStorage / cookie purge,
                    IndexedDB drop mid-session, offline → reconnect,
                    slow-3G, 503 flakes, 429 with no retry storm,
                    multi-tab same/different user, no-JS, hostile CSS,
                    clock skew ±1h / -2d, localStorage quota exhausted.

Phase 3 — mobile gestures (runs only on chromium-mobile / Pixel 7):
  09-mobile/    touch-target ≥44px audit, env(safe-area-inset-bottom)
                structural check, long-press (FeedListCard → ContextSheet,
                quick-tap negation, click-suppression), double-tap
                (feed card like + lightbox heart-burst, via synthetic
                pointer events to bypass the first-tap-fires-click trap),
                viewport reflow (portrait/landscape/narrow/phablet),
                plus fixme stubs documenting planned gestures (swipe
                lightbox L/R, swipe-down dismiss, pull-to-refresh,
                long-press-comment).

Cross-UA matrix (chromium-engine projects run @smoke only):
  chromium-pixel7, chromium-galaxy-s22, samsung-internet (Samsung UA
  emulation on Galaxy viewport), edge-android, plus webkit-iphone,
  chrome-ios, firefox-android, firefox-desktop — the latter four need
  libavif16 on the host (Playwright dep) but the configs are in place.

Infrastructure:
  - fixtures/test.ts central test.extend (api, db, adminToken, guest,
    host, signIn). Per-test DB truncate via the dev-only POST
    /admin/__truncate route, gated by EVENTSNAP_TEST_MODE=1.
  - helpers/sse-listener.ts, helpers/upload-client.ts (Node-side
    multipart for adversarial file-upload tests + JPEG/PNG/ELF magic
    constants), helpers/touch.ts (longPress / doubleTap / swipe /
    inlineStyle / computedStyle).
  - 10 page objects covering every route + UploadSheet/Lightbox.
  - global-setup waits for /health, logs in admin, disables every
    rate-limit and quota toggle.
  - .github/workflows/e2e.yml: PR check runs chromium-desktop + the
    smoke matrix in parallel, uploads playwright-report/ and traces on
    failure.

Findings the suite surfaces as live `[finding]` warnings (not silenced):
  1. /admin/login has no rate-limit or lockout (bcrypt cost only).
  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 (consider CSP +
     X-Content-Type-Options on /media/*).

Stack-internal docs live in e2e/README.md (UA tier table, Samsung
Internet escalation tiers A/B/C, debugging tips, roadmap).

Final tally: 134 passed / 0 failed / 9 skipped (test.fixme stubs for
not-yet-shipped gestures and one UI-upload-flow investigation).
