MechaCat02	117e67fa80	fix(auth,upload): close the admin lockout and four unbounded-input paths ... ADMIN LOCKOUT. admin_login looked its user up BY NAME. Migration 007 makes display_name unique per event case-insensitively and join had no reserved-name guard, so any guest joining as "admin"/"Admin"/"ADMIN" before the operator's first login made find(role == Admin) miss, the fallback create("Admin") violate that index, and `?` return a 500 — permanently, with no in-app recovery. Moderation, config and gallery release all gone; the fix was hand-editing the database. The root cause is the lookup key, not the creation. The name was never the identity. User::find_admin_for_event resolves by role, which makes the whole class of name collisions irrelevant — including the homoglyph bypasses of the new reserved-name list, which is now defence in depth rather than the control. Promoting the squatting row would be the obvious fix and is a serious mistake: it carries a recovery_pin_hash the guest knows, so it would hand them the admin dashboard via /recover, permanently, through a path needing no password. A separate row under a fallback name is worse UX and much better security. Verified against the real schema — the guest keeps their uploads, PIN and session under a freed name, and the role lookup then finds exactly one admin. Second, independent bug in that block: create() followed by a SEPARATE UPDATE ... SET role = 'admin' manufactures the same poisoned state if anything fails between them. Collapsed into create_with_role. UNBOUNDED INPUTS — one root cause, four places: validation ran after the allocation. - upload caption/hashtags used Field::text(), which buffers the whole field, on the one route whose DefaultBodyLimit is 576 MiB — so 576 MiB of heap per concurrent request in a 1 GiB container, with the length check running afterwards on a string already built. Now refused mid-read. - the hashtag CSV was never length-checked at all and was upserted tag by tag INSIDE the commit transaction, which holds FOR SHARE on the event row — one request could stall every other upload behind tens of thousands of round trips. Capped at 30 tags of <=50 chars. - /recover and /recover/request built rate-limiter keys by format!() from an unvalidated, unbounded display name, retained up to 24h in a map pruned hourly: the limiter itself became the memory-exhaustion primitive it exists to prevent. join validated first; that check is now shared by all three. /recover/request also had no per-IP ceiling at all — /join got one in 017, /recover in 019, and 019's own comment describes exactly this attack. It returns 204 rather than 400 on a bad name, because a 400 would be a new signal on an endpoint whose contract is that it cannot enumerate guests. - the SSE ticket store had no size cap, no per-session cap and no rate limit on its endpoint, while prune ran hourly against a 30s TTL. Now pruned on issue, capped, and rate-limited. At capacity it REFUSES rather than evicting a stranger's ticket — evicting would let one client deny SSE to the venue. Not one-ticket-per-session either: two tabs open their EventSources concurrently. PATCH /upload/{id} had no rate limit, no validation, and called invalidate_and_arm unconditionally — outside both `if let Some` guards. So PATCH {} bumped export_epoch and armed a fresh pair of full-gallery export workers every call; REGEN_DEBOUNCE bounds the rate of that, not the total work, so a guest could keep the keepsake permanently un-downloadable. All three fixed. The validation also resolves a divergence: upload normalised tags while edit stored them raw, so #Party via edit and party via upload became two hashtag rows. PIN LOCKOUT was an ordering bug before a policy one: the account-lock threshold (3) sat BELOW the per-(IP, name) ceiling (5), so three requests from one IP locked any guest whose name is on the feed, every 15 minutes, forever. The tier meant to protect a guest was the cheapest way to attack them. Ceiling drops to 4, threshold rises to 12, so locking a victim now needs at least three distinct sources. Brute-force cost is unchanged — 48 attempts/hour means 10k PINs still take ~208h regardless of IP count — and increment_failed_pin now decays the streak after 15 minutes, since the counter previously only cleared on success and honest typos accumulated across days. Both invariants are pinned by tests rather than comments. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-07-31 23:09:20 +02:00
MechaCat02	f275de5c8f	perf(feed): stop every feed page from aggregating the whole event ... v_feed computed like_count/comment_count with LEFT JOINs and a GROUP BY. Postgres CAN push `event_id = $1` and the keyset predicate through the view — verified with EXPLAIN, it uses idx_upload_event_created_id — but it CANNOT push ORDER BY ... LIMIT across a GroupAggregate. So every request aggregated every upload in the event, times its likes and comments, and only then sorted and took 21 rows. Cost grew with the event, not with the page. Measured on a throwaway database seeded to a real reception (1000 uploads, 100 guests, 27k likes, 10k comments), same query, same data: before GroupAggregate (actual rows=1001) -> Sort -> Limit 449 ms after Index Scan (actual rows=21) -> Limit -> SubPlans 0.58 ms migration 022 replaces the joins with correlated scalar subqueries, which puts the counts ABOVE the Limit so they run 21 times instead of 1001. Exactly equivalent, not merely close: "like" is keyed (upload_id, user_id) so COUNT(DISTINCT user_id) == count(*), comment.id is the PK so COUNT(DISTINCT c.id) == count(*), and the GROUP BY was on u.id so it was already one row per upload. Column names, order and types are unchanged, so no Rust changes. No new index needed — idx_like_upload and idx_comment_upload already match the subqueries. Note the existing load harness cannot see any of this: e2e/loadtest/driver.mjs creates no likes and no comments, so the expensive path had never been exercised. The amplifier, feed/+page.svelte: every open feed subscribed to `upload-processed` and refetched page 1 — the most expensive page — so ~100 open feeds each fired one per completed upload. Now gated on whether this client actually shows the card that changed, and the debounce is jittered, because a fixed delay just moves a simultaneous herd 800 ms later. Nothing is lost by skipping: a client without the card also missed its `new-upload`, and the reconnect `feed-delta` already schedules a refresh. Load shedding, because the above reduces the risk rather than removing it: db.rs set no acquire_timeout, so sqlx's 30 s default applied — longer than the frontend's own 20 s fetch timeout, meaning the browser gave up while the server kept holding the slot and the work was done for nobody. Now 5 s, and PoolTimedOut maps to 503 + Retry-After instead of a generic 500. That mattered because the upload queue classifies 5xx as transient and retries: a 500 sent the retries straight back into the saturated pool with nothing to pace them. PoolClosed stays Internal — it only occurs during shutdown, where a 503 would invite a retry against a server that is going away. The Retry-After extraction in into_response matches on variants, so unlike message() a missing arm is not a compile error — it would silently drop the header. Pinned by a test covering both retry-carrying variants. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-07-31 23:01:42 +02:00
MechaCat02	e52b2f1cd1	fix(upload): reclaim the bytes of uploads that never finish ... Reclaim was a dozen explicit remove_file calls on the handler's return paths. That covers every way the handler can FINISH and none of the ways it can simply STOP. When a client disconnects mid-body — a phone leaving wifi, iOS killing a backgrounded PWA, the user hitting back — axum drops the handler future at an .await inside field.chunk() and no return path runs at all. The partial file then survives forever: it has no upload row, so cleanup_deleted_media (row-driven) can never see it, and no sweeper covered the originals directory. The triggers are routine rather than adversarial, and the client keeps the blob and auto- retries on every `online` event, so one large video over bad wifi leaves several copies. Those bytes are also invisible to the quota while still consuming the free disk that compute_storage_quota divides among guests — so orphans silently shrink every guest's ceiling while the admin widget under-reports. All three volumes share one filesystem; the end state is Postgres unable to write WAL. TempFileGuard is an RAII guard, because dropping the future is exactly what runs Drop — it is the only construct that survives cancellation. Armed before the file can exist, disarmed only after tx.commit() succeeds. The twelve explicit cleanups are deleted so one owner holds the rule. The subtler half is the rename. It happens BEFORE the commit, so between them the file exists under its final name with no row pointing at it — an orphan that looks legitimate. The guard is RETARGETED there rather than disarmed, and the retarget sits on the same poll as the rename with no .await between, which is what makes that window uncancellable. sweep_orphan_originals is the backstop for the process that was killed, where no Drop can run at all. Hourly, alongside the existing sweeps: .tmp files past the window go unconditionally (a .tmp never has a row by construction), other files are batched 500 at a time through a single NOT EXISTS query. Two things that look like oversights and are not, both commented in place: - the 6h window is what makes the sweep safe against the rename-before-commit ordering, since a committing upload is briefly indistinguishable from an orphan. It must not be shortened to speed up a test. - the NOT EXISTS deliberately does NOT filter deleted_at IS NULL. A soft-deleted row still points at its file during its retention window, and reclaiming that is cleanup_deleted_media's job; filtering here would race the two sweeps and destroy the files the recovery window exists to preserve. Verified against the real schema: given a live original, a soft-deleted one and a true orphan, the query returns only the orphan.

MechaCat02	5969ec74ea	fix(compression): bound derivative retries so one bad upload can't loop forever ... The OOM in the previous commit was survivable; what made it an outage was that it repeated. The upload row is committed before compression starts, derivatives_rev defaults to 0, and set_derivatives_rev only runs on success — so a row whose processing killed the container survived at rev 0, and backfill_stale_derivatives (called unconditionally at every boot) re-selected it and re-ran the identical workload. With restart: unless-stopped that is an infinite kill loop, and every cycle also drops every SSE stream and truncates every in-flight upload. Verified end to end against the real schema in a scratch database: with the new guard the backfill selects the row on boots 1-3 and zero rows from boot 4 on, and a later success resets the counter. migration 021 adds derivative_attempts and derivative_last_error. The counter is incremented WRITE-AHEAD, before the work is attempted. This is the whole design: the failure being bounded is a cgroup SIGKILL, so no Err is returned, no error handler runs and no Drop fires. A counter bumped in a failure path increments zero times per crash and the loop would be unchanged. set_derivatives_rev clears it, so success is the only reset and both the live path and the backfill get it without a new call site to forget. Also in the backfill: - one task walking the rows sequentially instead of one task per row. A large backlog used to spawn thousands of tasks, each holding a pool handle and queueing on the same two permits, competing with live uploads for a whole boot. - LIMIT 200 per boot, and original_path <> '' replacing an IS NOT NULL that was dead (the column is NOT NULL; cleanup_deleted_media blanks it instead). - a once-per-boot error log naming how many uploads have given up. Without it the give-up is invisible — the loop stops, which is the point, but the photos keep a stale derivative forever with nothing to notice. Adds backfill_video_posters for the mirror-image gap: a video interrupted by a restart has its compression_status flipped processing -> failed by startup_recovery and is never re-enqueued, so thumbnail_path stays NULL for the rest of the event while the clip itself plays fine. It shares the same attempt budget, which means a genuinely posterless sub-second clip (Live Photo, mis-tap) stops being re-ffmpeg'd after three boots. That is intended, not a bug to fix later — Ok(false) is a normal permanent outcome there. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-07-31 22:52:48 +02:00
MechaCat02	a4bac03628	fix(compression): stop a single large PNG from OOM-killing the container ... An 8000x8000 RGBA PNG passes admission — 256,000,000 bytes is just under the 256 MiB max_alloc, and smooth content is under 3 MB on disk, far below any size cap. Processing it peaked at ~1250 MiB inside a 1 GiB cgroup. Measured, not argued: the new (ignored) test builds exactly that image and reads VmHWM around the pipeline, resetting the watermark via /proc/self/clear_refs so the number covers only the code under test. Three independent causes, all of which had to go: 1. The decode outlived everything. `resize` takes &self, and the no-downscale arm bound `img` into `display`, so the ~244 MiB buffer was still alive when oxipng ran — and oxipng decodes the PNG *again*, holding a full-size buffer per filter trial. The decode now lives in a block that yields the display derivative; the else arm moves `img` out, which is what makes "the block's value is the only survivor" true in both arms. 2. oxipng was unbounded in every dimension: preset 2 with timeout: None, and the default features pull in rayon, which evaluates filter trials concurrently with a full-size buffer each and has no Options knob to cap it. Now gated at 8 MP, given a 20 s timeout, and built with default-features = false so oxipng's own sequential shim is used. "filetime" is kept — without it preserve_attrs silently no-ops. Dropping "binary" also stops compiling clap/glob/env_logger (a CLI's deps) into the server image. 3. Even with those fixed it still measured 516 MiB, and compression_concurrency defaults to 2 — so two guests uploading big photos at once was another OOM, 1032 MiB against a 1 GiB limit. The cost is dominated by image's Lanczos3 resize, which accumulates in f32: the intermediate is new_width * old_height * 16 bytes, i.e. 262 MiB for this image — larger than the decode itself, and invisible to max_alloc. Two changes: the preview now derives from the 2048px display instead of re-resizing the original (one full-size pass, not two), and a job whose header-estimated peak exceeds 150 MiB takes an exclusive permit so two giants can never overlap. Ordinary photos (a 12 MP JPEG estimates ~50 MiB) never touch that permit, so throughput is unchanged for everything except the case that must not run in parallel. Chaining 8000 -> 2048 -> 800 for the preview is not a quality trade: a staged Lanczos3 downscale is standard for large ratios and is visually indistinguishable at 800px. The blocking half is now a free function so its memory behaviour is testable — the fix is a scoping property a future edit could silently undo.

MechaCat02	6fd75adb27	fix(ops): bound logs, drain ffmpeg's stderr, and stop three silent hangs ... Six independent operational defects, none of which needed a new feature to fix. Log rotation. Docker's json-file driver is unbounded by default, and those files land on the HOST filesystem — outside every deploy.resources.limits in the compose file, and on the same disk as postgres_data and media_data. A full disk stops Postgres writing WAL, which takes the event down. Capped at 10m x 3 per service. Log level. RUST_LOG was set in neither .env.example nor docker-compose.yml, so the code fallback WAS the production level — and it was `debug`, with tower_http=debug emitting a line per request and per response into that unrotated file. Now info, with tower_http=warn to state that those spans are diagnostics, not an access log. ffmpeg pipe deadlock. run_ffmpeg piped stdout and stderr and then called wait(), which drains neither. Once the ~64 KiB pipe buffer filled, ffmpeg blocked writing and wait() never returned — burning the full 120s timeout, twice per seek position, three times per compression attempt. And the timeout is an Err, so the end state was a soft-deleted upload: a guest's playable video destroyed by a poster-frame failure. Now stdout is null (nothing ever read it) and stderr is drained by wait_with_output, whose tail is logged on a non-zero exit. Note wait_with_output consumes the child, so the old kill-on-timeout is gone; kill_on_drop(true) already covers it. Readiness probe. /health never touched the pool, so the disk-full endgame above stayed green all the way down. Adds /health/ready (SELECT 1 under 2s) as a SECOND route — the compose healthcheck deliberately keeps pointing at /health, because caddy gates its startup on it and a DB-dependent probe would turn a Postgres blip into the reverse proxy refusing to start. api.ts request timeout. The abort timer was cleared in a finally around fetch(), which resolves on the response HEAD — leaving res.text() uncovered and no longer abortable. An upstream that sends headers then stalls the body hung the call forever. The timer now lives until the body is read, including the 204 path (which otherwise leaked a live 20s timer per no-content request). Upload XHR watchdog. The XHR had no timeout while processQueue held the isProcessing latch across it; on a half-open socket neither error nor abort ever fires, so the latch pinned and the queue wedged. Bounds SILENCE rather than total duration — a 500 MB video over a venue uplink legitimately runs 30+ minutes while making steady progress. Rejects as NetworkError, which is already the retryable branch, so a stalled upload now recovers like any network blip. IndexedDB failures. addToQueue called getDb() unguarded and handleSubmit had no catch, so a private-mode refusal or a QuotaExceededError on a large blob left a permanent "Wird hochgeladen…" spinner, no toast, and — for an in-app camera capture — the only copy of the photo gone. Now reported as 'failed', which keeps the staged files on screen and stays on the page. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-07-31 22:25:23 +02:00
fabi	402215d405	fix(video): extract a real poster frame, and stop claiming one that isn't there ... Both the compression worker and the HTML export ran the same invocation: ffmpeg -i <src> -vframes 1 -ss 00:00:01 -vf scale=… -y <out> `-ss` AFTER `-i` is an output-side seek. Against a clip of a second or less ffmpeg exits 0 and writes nothing, and both call sites gated on the exit status: - the worker wrote `thumbnail_path` and logged "thumbnail generated" for a file that was never created, so GET /upload/{id}/thumbnail 404s in the live feed; - the export listed media/<id>_thumb.jpg in data.json while the ZIP writer skipped the unopenable file, so the keepsake drew a broken image tile. Any clip at or under a second, which phones produce constantly — mis-taps, Live Photos, boomerangs. Not data loss; the .mp4 is in both archives and plays. Every server-side signal stayed green. New `services/video.rs` owns the extraction for both callers, mirroring the imaging.rs precedent (created for the same duplication, and it paid off when the max_alloc fix landed in both workers at once). Three changes in it: - `-ss` before `-i`, an input-side seek. NOT sufficient alone: verified against the production image, seeking to 1s in a 1.000s clip is still past the last frame and still exits 0 with no file. The 0s fallback is what actually fixes this, and 1s is tried first only because an opening frame makes a poor poster. - Verify the artifact, not the exit status. This is the check both sites were missing. - Carry compression.rs's 120s timeout. export.rs had NONE — a hung ffmpeg there would strand the job at `running` and the keepsake would never complete. The worker's call used `?`. Tightening the check without also making a missing poster non-fatal would have been far worse than the bug: every sub-second clip would fail compression, exhaust its retries and be soft-deleted. It now logs a warning and leaves `thumbnail_path` NULL, which FeedListCard, VirtualFeed and LightboxModal already handle. The export now sets `thumb: ""` and skips the manifest entry when there is no poster — and does the same for the IMAGE branch, whose decode failure left the identical dangling reference. No viewer change was needed: +page.svelte already guards `{#if post.media.thumb}` and falls back to a video tile with a play glyph. The comment claiming "viewer handles missing thumbs gracefully" was true about the viewer and false about what the backend sent — the guard never fired because the string was never empty. e2e/specs/06-export/export-video.spec.ts had DOCUMENTED this as intended behaviour ("the fixture clip is <1s, so ffmpeg extracts no thumbnail frame — but exits 0 … that's the intended shape here"). sample.mp4 is exactly 1.000s, so every video test in the suite ran at that boundary and none ever fetched the poster. That comment is now corrected to say what it actually was. Tests: 2 unit; a new sample-5s.mp4 fixture so the ordinary first-seek path is covered at all; video-playback now FETCHES the poster rather than asserting the attribute (the one extra request that nine rounds of green never made); a new spec covering both fixtures plus the mirror that a posterless video still uploads and plays; and a keepsake spec asserting every <img> in the opened viewer resolves — naturalWidth === 0 is exactly the broken-tile case, whatever produced it.

fabi	3bcb7c6a76	fix(deploy): close the POSTGRES_PASSWORD trap that broke a fresh deploy either way ... README step 2 said to set "DOMAIN, JWT_SECRET, ADMIN_PASSWORD_HASH, EVENT_NAME, etc." -- POSTGRES_PASSWORD was not in that list. .env.example said to set it and keep it in sync with DATABASE_URL. The two documents disagreed, and both readings ended badly. Branch A, README verbatim: the stack came up GREEN and healthy on CHANGE_ME_use_a_strong_password -- a database credential published in the public repo. The production secret guard covered JWT_SECRET and ADMIN_PASSWORD_HASH, and nothing anywhere looked at the Postgres password. Branch B, .env.example verbatim: a permanent restart loop, "password authentication failed for user eventsnap". The guard's own design made Branch B near-certain. It stops the APP on the first `docker compose up -d` -- but not the `db` service in that same command, which initialises its data directory and bakes in whatever password was in .env at that moment. POSTGRES_PASSWORD is honoured ONLY at initdb. So the intended recovery -- see the refusal, fix your secrets, boot again -- was exactly the sequence that broke it. Nothing in the error named the cause, and the remedy (`down -v`) is both unguessable and the one command you must never run once real data exists. Three changes, which have to ship together: the guard alone would just move operators out of Branch A and into Branch B. - The guard now rejects a placeholder DATABASE_URL in production (the password rides in that URL, which is what the app actually reads). Branch A can no longer boot. - It reports EVERY unset secret in one message instead of returning on the first. Fixing two secrets used to cost two boot cycles, on a stack where Caddy waits on the unhealthy app throughout, and each avoidable cycle is another chance to reach for -v. - A 28P01 handler in db.rs turns the unguessable failure into a self-explaining one: it names the initdb semantics, gives `down -v` with an explicit "deletes db + media + exports, no undo", and gives the ALTER ROLE alternative for when data already exists. Docs: step 2 now names POSTGRES_PASSWORD and says every secret must be set BEFORE the first up; the troubleshooting block covers the auth-failure loop and both remedies. Also replaces htpasswd (apache2-utils -- not on a stock VPS) with `docker run --rm caddy:2-alpine caddy hash-password`, an image the stack already pulls, in README, .env.example and the guard's own message. Verified the output ($2a$14) against the shipped $2y$12 example. Verified on a real Postgres, not just in tests: Branch A refuses and names DATABASE_URL; all three placeholders report in one boot; a volume initialised with one password and connected to with another prints the diagnostic; an unrelated connect failure (dead port) stays silent. 8 unit tests, including that non-prod ignores all of it so the e2e stack is unaffected.

fabi	08d92b7531	fix(audit-7): keepsake viewer integrity, readable archives, quota_tolerance floor ... Seventh round, both defects in the keepsake — the one artifact that leaves the system entirely, and so the one where a green server-side signal carries no information at all. Squashed from 2 commits, original messages preserved below. ──────── fix(export): stop a caption bricking the viewer, and ship readable archives Two defects in the keepsake, both silent server-side and both only visible by extracting the real artifact and trying to use it. 1. A CAPTION COULD BRICK THE VIEWER. The viewer's data is inlined as `<script>window.__EXPORT_DATA__={…}</script>` -- it has to be, since guests open index.html over file:// where fetching a sibling data.json is blocked. The escape was `</` -> `<\/`. Against XSS that holds; I fired `</script><img src=x onerror=…>` through a real Chromium parser and it round-trips inert. It does not stop the caption steering the HTML TOKENIZER. `<!--<script` with no later `-->` drives the parser into script-data-double-escaped state, where the template's own `</script>` only steps back to script-data-escaped instead of closing the element. Everything after it -- including the viewer bundle -- is swallowed as script data. Nothing executes and nothing leaks: `__EXPORT_DATA__` is simply never assigned and the keepsake opens blank. A denial of the deliverable, not an XSS. Reproduced in Chromium before changing anything, and the near-miss is worth recording: `<!--<script>alert(1)</script>-->` comes back CLEAN, because the trailing `-->` returns the parser to script-data state. A probe using the terminated form quietly repairs the thing it is testing for. Fix: escape every `<` as `<`, not just `</`. `<` never appears in JSON structural syntax -- only inside string values -- so a global replace is sound, and one rule covers `</script`, `<!--` and `<script` together. That is the point: the old escape was named for the single case it handled. Only the INLINED copy is escaped; data.json is written separately, in no HTML context, and stays literal. 2. EVERY ENTRY IN BOTH ARCHIVES WAS STORED MODE 0000. `ZipEntryBuilder::new` leaves the external file attribute at zero and async_zip's host compatibility defaults to Unix, so `unzip -Z` showed `?---------` on every line of both Gallery.zip and Memories.zip. Windows Explorer ignores Unix modes, which is why this survived; on Linux and macOS `unzip` faithfully applies what the archive asks for and the guest gets a folder of photos none of which they can open. Unconditional -- every keepsake ever produced, no hostile input required -- and invisible server-side: the export succeeds, the ZIP is well-formed, the job writes `done`, /export/status is green. Found by accident. The browser test for defect 1 failed with ERR_ACCESS_DENIED on file://, which looked exactly like a Playwright sandbox quirk; I twice "worked around" it (fresh context, then a separately launched browser) before checking the extracted files and finding mode 000. The workaround was suppressing a real bug. Both workarounds are gone -- the ordinary `page` fixture loads the archive fine now. Fix: all six ZipEntryBuilder sites route through one `keepsake_entry` helper stamping `S_IFREG | 0644`, so the mode cannot be forgotten at a call site. Tests: 3 unit (no `<` survives; the payload still decodes to the original value, because this is a transport encoding and not a sanitiser; a clean payload is untouched) and 2 e2e that release for real, download the real archives, and check them from outside the app -- one opening index.html over file:// in Chromium and asserting the viewer booted, the captions came back verbatim and nothing executed; one asserting every stored mode and every extracted file is readable. Both assertions verified to FAIL against the pre-fix artifacts. ──────── fix(admin): reject quota_tolerance = 0 instead of silently blocking every upload Zero is inside the documented 0–1 range and catastrophic. The per-user limit is `free_disk * tolerance / active_uploaders`, so a tolerance of 0 makes every limit 0 and refuses EVERY upload -- mid-event, with "Du hast dein Upload-Limit für dieses Event erreicht", an error naming the wrong cause entirely. An admin reaching for an off-switch wants `storage_quota_enabled`; the rejection now says so. Rejecting the value rather than raising the floor. A floor of 0.01 was the obvious fix and it is wrong: very small tolerances are legitimate -- they are how a large disk is throttled down to a sensible per-guest ceiling, and how the quota specs steer it (tolerance = target * active / free lands around 1e-5 on the 174 GB volume this suite runs on). A floor would forbid real configurations, and would have broken the entire storage-quota describe block, to prevent one typo. Verified: those four tests still pass. Tests: the rejection, that the stored value is untouched (validation fully precedes any write), and the mirror -- 0.00001 still round-trips -- so the guard can't quietly become a floor later.

fabi	06bc9ddcb3	refactor(export): share the visibility filter between the row query and the estimate ... `query_uploads` selects the rows the archives are built from; `estimate_export_bytes` sizes them for the disk preflight. They stated the same WHERE clause separately, and the direction of drift matters: an estimate that MISSES rows the archive writes under-reserves, which is precisely the ENOSPC the preflight exists to prevent. The integration test claimed to guard this and cannot. Both sides of `the_estimate_sums_exactly_the_rows_the_archive_will_contain` are `SRC:`-marked hand-copies in tests/common/mod.rs -- neither is production code -- so drift means production moved while both copies sat still, and the test goes on passing. The convention is sound for pinning behaviour; it is structurally incapable of detecting divergence from the thing it copies. So fix it where it can be fixed. One `export_visibility_where!()` fragment, `concat!`-ed into both queries at compile time (still `&'static str`, no allocation), with the `u`/`usr` alias contract stated. Divergence is now impossible by construction rather than watched for. The tests keep their value and lose the overclaim: the docstrings now say they pin WHICH uploads may be counted -- each excluded row in the fixture is excluded by a different predicate, so weakening any one of them still fails here -- and say plainly that they do not detect drift, with a pointer to what does. No behaviour change. The filters were verified identical before the hoist (`u.event_id = $1 AND u.deleted_at IS NULL AND usr.uploads_hidden = FALSE AND usr.is_banned = FALSE`); 99 backend tests still pass.

fabi	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.

fabi	31faccfdf8	fix(audit-4): refuse undecodable images at admission, stop retrying permanent failures ... Fourth round: reject at the door what the worker can only fail on, and stop retrying errors that cannot succeed — while keeping IoError retryable so ENOSPC still gets another attempt. Squashed from 2 commits, original messages preserved below. ──────── fix(upload): refuse undecodable images at the door, and stop retrying them Two halves of the same complaint: an oversized photo was accepted with a 201 and then silently soft-deleted minutes later, after the worker had burned six seconds of backoff re-reaching a conclusion it could not change. Admission. The compression budget now runs at upload time, against the header only, so a guest is told immediately and told why: "Bild hat zu viele Bildpunkte (ca. 99 Megapixel) und kann nicht verarbeitet werden. Bitte verkleinere es und lade es erneut hoch." instead of watching the photo vanish behind a vague "could not be processed" — which arrived only if they happened to still be on the feed with that card loaded. Nothing is stored, so there is no row to soft-delete and no orphan for the sweep to reclaim. Admission and the worker share ONE function (`decoder_within_budget`), so they cannot drift apart and start disagreeing about what is acceptable — a photo accepted at the door and rejected by the worker would be worse than either behaviour alone. The worker keeps its own check: the backfill decodes files that predate this check, and defence in depth is the whole reason the budget exists. Retries. The loop retried every failure, including ones that are a property of the input. An image over the budget, a corrupt file, an unsupported format: each fails identically on all three attempts, so the only effect was 2s + 4s of sleep and three near-identical warnings before the same outcome. `is_permanent_image_error` classifies the `ImageError` variants that cannot change between attempts — Limits, Unsupported, Decoding — and the loop gives up on those at once. `IoError` is deliberately excluded: an ENOSPC while writing a derivative is exactly the transient case the retry exists for, and misclassifying it would turn a blip back into the data loss round 1 fixed. Measured: retry log lines went from 3 per oversized upload to 0. Tests: unit tests for both sides of the classifier (a Limits error is permanent, a missing file is not) and for admission agreeing with the decoder on accept AND reject. The e2e spec is rewritten for the new contract — 400 with an actionable message, nothing stored, backend alive after a burst of four — plus a mirror asserting an ordinary photo still uploads and processes, since a budget that rejected everything would satisfy the other two. ──────── fix(upload): narrow the admission check to the memory budget only The admission check I just added rejected ANY image the decoder couldn't build — corrupt, truncated, or unsupported, not only over-budget. That broke two adversarial tests, and they were right to break. 07-adversarial/file-upload-attacks pins, deliberately, that acceptance follows the MAGIC BYTES: a payload whose first three bytes are a JPEG header is accepted regardless of what follows, because the security property under test is that the client-declared Content-Type has no influence. Both failing cases upload 1024 bytes of JPEG magic followed by zeros. Rejecting those at admission is a different, broader contract than the one asked for, and rewriting an adversarial test to match new behaviour is precisely the thing that needs justifying rather than doing quietly. So admission now checks only what it was meant to: `exceeds_decode_budget` returns true solely for `ImageError::Limits`. A corrupt file goes to the compression worker exactly as before — which handles it gracefully and, since the retry classifier in the previous commit, no longer burns backoff on it. The resource guard is the part that had to move earlier; nothing else did. Tests: the size agreement between admission and the worker is still asserted in both directions, plus a new one writing a magic-bytes-only stub and asserting admission accepts it WHILE the worker still rejects it — pinning the boundary between the two checks so a future widening fails here rather than in the adversarial suite.

fabi	06ade4e158	fix(audit-3): restore the decode allocation guard, route /health in production ... Third round. The decode allocation guard is a regression from round 1: swapping reader.decode() for into_decoder() silently dropped the max_alloc enforcement while keeping the comment that claimed it held. Squashed from 3 commits, original messages preserved below. ──────── fix(imaging): restore the decode allocation guard I removed in round 1 This is a regression I introduced, not a pre-existing gap. Before 05948d8 the compression worker used `ImageReader::decode()`, which does: let mut decoder = Self::make_decoder(format, self.inner, limits.clone())?; limits.reserve(decoder.total_bytes())?; // enforces max_alloc decoder.set_limits(limits)?; Reading the EXIF orientation tag needs `into_decoder()` instead, and that skips the reserve entirely — the crate's own FIXME concedes `from_decoder` doesn't compensate. Nothing else enforces `max_alloc`: the JPEG decoder's `set_limits` only checks support and dimensions. So the 256 MiB budget has been inert since that commit, and round 2 then propagated the weakened path into export.rs through the shared helper, in a commit whose message claimed the helper "carries" the decompression-bomb cap. It didn't, and the comment saying max_alloc "hard-caps the decode allocation" was simply false. What was left was only the per-axis cap, which permits 12000x12000 — 412 MiB decoded, 824 MiB for the two concurrent decodes the worker runs by default, against a 1 GiB container. Deploy-blocking right now because bumping DERIVATIVES_REV makes the first boot after a deploy re-decode the entire gallery two at a time: an OOM kill there restarts the container, which re-runs the backfill. A boot loop, on the first deploy of these fixes. Re-add the reserve exactly as `decode()` does it. Per the budget decision it stays at 256 MiB (~89 MP for RGB8, above any mainstream phone's real output); two concurrent decodes now peak at 512 MiB. Oversized images take the graceful path from round 1 — original retained, quota refunded, upload-error toast — and fail after the header parse but BEFORE any pixels are read, so they cost a header read rather than an allocation. Measured peak during a concurrent oversized burst: 3.0 MiB. Test parity is the other half, and the reason this was invisible: the e2e app container had NO memory limit while production is capped at 1 GiB, so a decode that would OOM-kill production simply succeeded in CI. Mirror the 1 GiB cap in docker-compose.test.yml. That is the third divergence of this shape, after WebKit missing from CI and /health existing only in Caddyfile.test. Tests: a fixture that is 568 KiB on disk and 283 MiB decoded (11000x9000 = 99 MP, deliberately UNDER the per-axis cap so the axis check cannot be what rejects it). A unit test asserts the refusal — it fails against the old code, which decoded it into an 11000x9000 buffer — with a companion asserting an ordinary photo still decodes AND still gets its orientation applied, so the guard didn't become a blanket refusal. An e2e test uploads it singly and as a concurrent pair, asserting compression lands in 'failed' and the backend is still serving and still processing afterwards. ──────── fix(deploy): route /health in production, and actually apply Caddyfile changes Two defects in the update procedure I wrote last round, both of which make a successful-looking deploy a lie. 1. The documented health check could never pass. `curl -fsS https://DOMAIN/health` 404s against a perfectly healthy production stack. The backend registers /health on its ROOT router, not under /api/v1, and the production Caddyfile proxies only /api/* and /media/* — so /health fell through to the SvelteKit catch-all, which has no such route and returns its 404 page. With -f, curl exits 22 and the `&& echo` never runs. My own gloss ("Anything other than ok means check the logs") then sent the operator chasing a phantom outage. e2e/Caddyfile.test has carried `reverse_proxy /health app:3000` since it was written — precisely because the catch-all would otherwise swallow it. Production never did. Per the fix-the-gap-not-the-doc call, production gets the same line, and /health joins the no-store matcher so a cached response can't report the last known state instead of the current one. Verified by running the production Caddyfile against the real backend: /health -> 200 "ok", Cache-Control: no-store, with /api/v1/event and / unaffected. 2. The sequence never reloaded Caddy, so a Caddyfile-only change was dropped. `--build` only rebuilds services with a `build:` section, and caddy is a pinned upstream image. Compose decides whether to recreate a container from its config hash, which covers the mount SPECIFICATION but not the mounted file's CONTENTS — so a git pull that changes ./Caddyfile produces no delta, Compose reports `Running`, and Caddy serves its old config indefinitely. Exit code 0 throughout. Round 1's iOS download fix (137c4ee) is exactly this shape: Caddyfile plus four e2e files, so 100% of its production effect is in that one file. Following the README to the letter deployed it, showed both image IDs changing, and left iOS downloads broken. Demonstrated rather than assumed — added a probe header to a Caddyfile, ran the old sequence (`up -d --build`): header absent, change silently dropped. Ran the new step 4 (`up -d --force-recreate caddy`): header served. `--force-recreate` rather than `restart` or `caddy reload` because the bind mount is resolved to an inode at container-create time and git pull replaces the file rather than editing in place, so a restart can re-read the stale content — the exact failure I hit in round 1 when `caddy reload` didn't pick up an edit. Also rewrites the "db and caddy are untouched … so data volumes survive" sentence. I wrote it as reassurance; "caddy is untouched" was the bug. ──────── chore: take the Bash(*) permission change back out of the shared settings `.claude/settings.json` is committed and applies to anyone who clones. Fabi's local `allow: ["Bash(*)"]` plus deny list ended up in it, inside f0d69f1 — a commit about the image decode guard, which has nothing to do with permissions. That was my mistake, twice. The file was already modified when I started the round: my `git status --short` check printed "(clean)" from an unconditional `echo` rather than from the status output, so I read a dirty tree as clean. Then `git add -A` swept it into an unrelated commit, and I reported afterwards that I had left it untouched. Neither the check nor the claim was true. Restores the shared file to its previous three narrow entries. The permission setup itself is preserved, moved to `.claude/settings.local.json`, which `.gitignore:34` covers precisely so per-user permissions stay per-user — the existing 442 entries there are kept alongside it. Not rewriting f0d69f1 to erase this: main is unpushed so it would be safe, but a visible correction is worth more than a tidy history, and a rebase across the merge commits carries more risk than the mistake does.

fabi	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.

fabi	0c0eed885a	fix(audit-1): media gating, per-user limits, moderation UI, upload integrity ... First audit round: a blocker and eight high-severity findings across the media access gate, the guest-facing rate limiters, host moderation, and the upload pipeline — plus the backup commands and the e2e/production divergences that hid several of them. Squashed from 7 commits, original messages preserved below. ──────── fix(export): let the keepsake download through X-Frame-Options on iOS The keepsake download navigates a hidden, same-origin iframe (deliberately: a top-level navigation to a 404/429 would unload the PWA). Caddy stamped a site-wide `X-Frame-Options: DENY` that also covered the proxied `/api/*`. Blink hands a `Content-Disposition: attachment` response to the download manager at the network layer, so Chromium never noticed. WebKit enforces XFO on the frame navigation first and aborts the load — so on iOS Safari, the app's primary platform, tapping Download did nothing at all, silently. Carve the two export endpoints out to SAMEORIGIN, which still blocks cross-origin framing. Implemented as two disjoint matchers rather than an override: Caddy applies the FIRST `header` directive outermost, so it wins on write and a later, more specific `header` is silently ignored (verified against the running test stack). Also close the test gap that let this ship: - `06-export` ran on chromium-desktop only; add it to `webkit-iphone`, the only engine that enforces XFO on the download frame. - No test in the suite ever clicked a download button — every archive assertion used Node `fetch`, which has no frame and no XFO enforcement. Add a spec that clicks it and awaits a real `download` event. Verified falsifiable: with the blanket DENY reinstated it fails and reports the WebKit refusal as the cause. - Fix `ExportPage`'s card-scoped locators, which matched nothing: the cards carry `class="card p-5"` (a Tailwind `@apply` component class), never the `rounded-xl` the page object looked for. This had left the "shows enabled download buttons" test red on main. ──────── fix(media): close the percent-escape bypass of the media gate `/media/%70reviews/{id}.jpg` served a taken-down photo to anyone, unauthenticated. Verified against the running stack: the literal path 404s, the escaped one returned 200 with the full image. Same for displays, thumbnails and originals, and any escaped byte in any position works. Cause: the block was four `nest_service("/media/previews", 404)` route matches sitting above a `ServeDir` on `/media`. axum matches on the RAW path (matchit does no percent-decoding), while `ServeDir` percent-decodes when it resolves the file. So `%70reviews` missed every blocker, fell through to the ServeDir, and was decoded back to `previews/` on disk — reaching the bytes with no soft-delete and no ban-hide check. That defeats a host takedown, which is the entire point of the gate. Remove the `/media` route tree outright instead of racing the decoder. Nothing needs it: every media URL the backend emits is already a gated `/api/v1/upload/{id}/{original,preview,display,thumbnail}` alias (handlers::feed), the frontend contains zero `/media/` references, and the `/media` in config.rs/disk.rs is the filesystem path while `media/` in export.rs is a path inside the zip. `/media/**` now 404s regardless of encoding. The route's own comment already said it "serves nothing" — it wasn't a backstop, it was the vector. Caddy keeps proxying /media/* deliberately: the app 404s it, and forwarding means the e2e gating specs exercise the app's refusal exactly as production would rather than being masked by the SvelteKit 404 page. Extend the gating spec with the encoded variants — asserting only the literal spelling is what let this sit undetected. ──────── fix(rate-limit): key the guest-facing limiters per user, not per IP At a venue every guest is behind one NAT, so an IP-keyed limiter hands the whole party a single bucket. On a fresh deploy 12 guests arriving together meant 5 joined and 7 were turned away, with no Retry-After telling them when to retry. `/feed` (60/min) and `/export` (3 per DAY — the fourth guest to fetch their keepsake locked out until tomorrow) had the same defect. `feed_delta` was already keyed per-user and its comment states the exact rationale ("so one client can't starve others behind a shared NAT"); this makes its siblings match. - feed:{ip} -> feed:{user_id} (auth was already in scope) - export:{ip} -> export:{user_id} (resolved from the download ticket's session, which was previously looked up and discarded) - join:{ip}: pre-auth, so there is no user to key on. Split in two — a loose per-IP ceiling that only bounds raw volume (new `join_ip_rate_per_min`, default 60, migration 017), plus the real 5/60s anti-spam bucket keyed per (ip, name), mirroring the existing `recover:{ip}:{name}`. admin_login / recover / pin_reset_req stay IP-keyed on purpose and are now commented as such: they guard credential guessing, where a per-user or per-name key would just hand an attacker a fresh bucket per guess. Retry-After: the machinery existed but 7 of 8 sites called `check()` and hard-coded `None`, so a throttled client was told to back off but never for how long. Delete the bool `check()` wrapper entirely so `check_with_retry` is the only entry point and the delay cannot be discarded by accident. Also surface it for the PIN lockout, where the deadline was already known. Fix the "unknown" fallback while here: every client_ip() caller passed that literal, so any request without X-Forwarded-For — anything reaching the app directly rather than through Caddy — shared ONE global bucket. Serve with connect-info and use the peer address. Tests: the reseed forces every limiter toggle off before each test, which is why this whole class was invisible. Add 01-auth/rate-limit-shared-nat, which enables them and asserts 12 guests share an IP without collision, that one guest hammering their own name IS still throttled (so the fix re-keys rather than removes the limit), and that feed/export buckets are per-user. Retarget the ddos join test at the new per-IP ceiling — it asserted the defect. Also seed `admin_login_rate_enabled` (read by the handler, seeded by no migration and no reseed) and register `join_ip_rate_per_min` in the admin config allowlist. Unrelated pre-existing red test fixed: 01-auth/join asserted a "Willkommen!" heading the wedding redesign removed. ──────── feat(moderation): let a host remove a guest's photo or comment from the UI `DELETE /host/upload/{id}` and `DELETE /host/comment/{id}` were complete on the backend — transactional, SSE-broadcasting, audit-logged — and had zero frontend callers. The feed context sheet offered "Löschen" only when `target.user_id === myUserId`, so the only lever a host actually had against an unwanted photo was banning the uploader. That is both disproportionate and ineffective. A ban doesn't retract what was already posted, and it makes things strictly worse for comments: the ban check runs BEFORE the ownership check on the guest delete route, so banning an abusive author leaves their comment on screen and permanently undeletable by them. With no host affordance, nobody could remove it at all. - feed: hosts/admins get "Beitrag entfernen" on other people's posts, routed to the host endpoint (the guest route 403s anything the caller doesn't own) with moderation-specific confirm copy. Own-post "Löschen" is unchanged. - lightbox: same for comments, via /host/comment/{id}. - Ban semantics are deliberately untouched (USER_JOURNEYS §10 — banned users keep read access and cannot write). The deadlock is broken by giving the host a way in, not by loosening the ban. Live role (this had to come first). `getRole()` decodes the JWT claim, but the token is never reissued — the backend slides the session row forward and treats the DB row as authoritative. The claim is therefore frozen for the token's lifetime: up to 30 days. A guest promoted at the party saw no Host-Dashboard and no moderation actions until they signed out and back in, even though `/me/context` had been returning their real role on every page load and 4 of its 6 call sites dropped the field on the floor. Add `role-store.ts`: seeded from the claim so there's no flash of the wrong nav, then corrected by every `/me/context` response. Point the ad-hoc `getRole()` callers at it (account, upload, host, admin, and the new feed gate). The host and admin dashboards now derive `myRole` reactively, so a demotion disables their controls immediately instead of at next login. Tests: 04-host/moderation-ui drives the real UI — host removes a guest photo and it's gone from /feed server-side; a plain guest is offered nothing on someone else's post (the mirror that keeps the first test honest); a promoted guest gains the dashboard on reload while their token still carries `role: guest`; and a host removes the comment of an already-banned guest, asserting first that the author's own delete 403s so the deadlock is real. ──────── fix(upload): stop destroying originals, apply EXIF orientation, surface rejections Three defects in the same pipeline, each of which loses a photo or misrepresents one. 1. A transient error destroyed the guest's only copy. `process`'s error arm unconditionally `remove_file`d the original. Every failure routed there: `create_dir_all`, both derivative `save_with_format` calls (disk full is the canonical case, and it arrives exactly when many guests upload at once), a panic inside the image codec, or a momentary DB-pool exhaustion. The row is only SOFT-deleted, so the bytes were the sole unrecoverable part — and they were the part we deleted. The author already knew this was wrong next door: `backfill_missing_display` says it "must NEVER soft-delete an upload that already has a working preview". Retry up to 3 times with backoff (re-checking the e2e generation guard after each sleep), and on final failure keep the refund + soft-delete but leave the original on disk, logging its path. A failed upload is now recoverable instead of gone. 2. Every portrait photo was stored sideways. Phones don't rotate sensor data — they record the camera orientation in EXIF and store the pixels as shot. `decode()` returns those raw pixels and the JPEG re-encode writes no EXIF, so the 800px preview, the 2048px diashow display and the keepsake were all rotated 90°, while "Original anzeigen" rendered upright because the original keeps its tag. That asymmetry is why it reads as a viewer bug. There was no EXIF handling anywhere in the repo and no exif crate. Read the tag via `into_decoder()` (which carries the decode Limits through, so the decompression-bomb cap is untouched) and apply it. Missing/malformed tags fall back to NoTransforms — most images have none. Existing derivatives are already baked wrong, so migration 018 adds `derivatives_rev` and `backfill_missing_display` becomes `backfill_stale_derivatives`: it now also picks up anything below the current rev and regenerates it once from the original, which still carries its EXIF. Videos are marked current in the migration — ffmpeg already honours the rotation matrix. Bump DERIVATIVES_REV for any future change that invalidates derivatives. 3. A rejected upload vanished without a word. `UploadQueue.svelte` — 162 lines holding the ONLY renderer of an item's error text, the only "Erneut" retry button and the only rate-limit countdown — was never imported anywhere, so `retryItem`, `removeItem` and `clearCompleted` were unreachable at runtime. On a terminal rejection the store purged the blob and wrote a clear German reason into `entry.error` "so the UI shows a clear reason". There was no such UI. And `uploadBadgeCount` counted only pending/uploading, so the badge decremented exactly as if the upload had succeeded. Mount the queue on /upload, toast the reason immediately (the flow sends the user to /feed straight after staging, so the list alone would still miss them), and count blocked/error in the badge so a failure can't read as success. Tests: 02-upload/exif-orientation uploads a 40x20 fixture tagged Orientation=6 and asserts both derivatives come back PORTRAIT, with a sanity check that the source really is stored landscape. 02-upload/rejection-visible bans the uploader between staging and sending, then asserts the toast, the queue row with the server's reason, and that the item is still counted. Note: 02-upload/quota's 4 failures are pre-existing and unrelated — see the next commit. ──────── docs(backup): make the backup commands work; fix the e2e/prod divergences Backup. Both documented commands failed on the shipped stack, and the sentence explaining them was wrong too: - `pg_dump $DATABASE_URL` — `DATABASE_URL` is only ever in the compose environment, never an operator's shell, and it points at `db:5432`, which is compose-internal DNS. The app image has no postgres client either. - `> /media/backups/…` — `/media` is a named volume mounted inside the app container, not a host path, and nothing ever creates a `backups` subdirectory. - `rsync /opt/eventsnap/media/` — that path does not exist anywhere. - "a single path to back up" — false, and dangerously so: exports were moved to their own `exports_data` volume precisely so a keepsake (which contains every photo in the event) can't be served off the media tree. Backing up only `media_data` silently loses every generated keepsake. Rewritten as three commands — db via `docker compose exec -T db pg_dump`, and one `docker run … tar` per volume — all verified against the running stack. The volume mounts use `/src`, not `/media`: I hit the footgun while testing this. Docker pre-populates an EMPTY volume from the image's own directory and chowns it to match, so `-v media_data:/media alpine` tars alpine's cdrom/floppy/usb, writes them into the volume, and leaves it root-owned so the non-root app can no longer write. Mounting where the image has nothing avoids all of it. Documented inline so the next person doesn't rediscover it. Also correct the architecture notes: `/media/*` no longer routes to the backend (that static tree was removed as a gating bypass), and `exports_data` was missing from the volume list — the one volume an operator most needs to know about. e2e stack: add the `EXPORT_PATH` + `/exports` volume it was missing. The file says "mirrors production layout"; without these, exports landed on the container's writable layer at the default path, so export-leak and export-video wrote real archives into ephemeral storage and the "exports live outside media" invariant was never actually exercised. Pre-existing red test, unrelated to the audit: all four 02-upload/quota tests have been failing since 4464147 "stop /me/quota leaking raw disk to guests" (2026-07-19), which post-dates the spec's last edit. `setLimitTo` calibrated `quota_tolerance` from `free_disk_bytes` read through the GUEST's token — a field that commit deliberately zeroes for non-staff. Dividing by it yields a NaN tolerance, so every test in the block died in the helper. Read the calibration inputs through a staff token and keep reading the ceiling back through the guest, whose limit is the thing under test. ──────── test(e2e): document why WebKit can't run the client-queue upload tests Three 02-upload tests have been failing on `webkit-iphone` on main — `02-upload` was already in that project's testMatch, so this is pre-existing red, not something the audit work introduced. Root cause is the harness, not the app. Playwright's Linux WebKit build cannot store Blobs in IndexedDB at all: `put()` fails with "UnknownError: Error preparing Blob/File data to be stored in object store". Confirmed it is not about how Playwright delivers files — a Blob constructed in-page with `new Blob([bytes])` fails identically, while Chromium stores both that and a `setInputFiles` File without complaint. That breaks every test driving the composer (FAB → UploadSheet → /upload → submit), because `handleSubmit` awaits `addToQueue`, which persists the file before it can navigate. The symptom is a submit button stuck on "Wird hochgeladen…" and a timeout waiting for /feed — which reads like an app hang and cost real time to run down. Skip those four (the three above plus the new rejection-visible) on WebKit only, behind a named helper carrying the full explanation, so the next person gets the answer instead of the investigation. Deliberately narrow: WebKit still runs every API-driven upload test, all of 01-auth, 03-feed and 06-export — including the keepsake download, which only WebKit can meaningfully verify. Chromium continues to run all 14. Worth being explicit, since these tests exist to protect iOS: real Safari supports Blobs in IndexedDB, so this is NOT evidence that the offline upload queue is broken on the platform. It does mean that guarantee is currently unverifiable in CI and rests on Chromium coverage plus manual device testing. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>	2026-07-28 19:14:37 +02:00
MechaCat02	3fb1b5d80d	feat(comments): hide every comment mention when COMMENTS_ENABLED=false ... The kill-switch previously left comment UI/text visible in several places. Sweep the whole surface so a comments-off instance shows no trace: Frontend (main app): - VirtualFeed grid tile: gate the comment button/count on $commentsEnabled (was ungated — the only feed surface still showing it). - admin stats: hide the "Kommentare" count card. - UploadSheet "Uploads geschlossen" notice, host ban-modal description, and host/admin unban confirmations: drop the "…und kommentieren" wording. - export page: drop "Kommentaren" from the keepsake description. Keepsake export (had no concept of the flag): - export.rs: thread comments_enabled into the exported data (ViewerEvent), wired through spawn_export_jobs/recover_exports and their call sites (host.rs, main.rs). - export-viewer: gate comment counts (list + grid) and the lightbox comments section; older exports without the field default to enabled (?? true). Backend still 403s comment writes when disabled (unchanged) — this is the UI half so stale clients and archives match. Verified on the running stack (COMMENTS_ENABLED=false): /event reports comments_enabled=false, a regenerated keepsake embeds "comments_enabled": false with no comment UI, and the uploads-closed notice renders "…ansehen und liken."

MechaCat02	5009590882	feat(diashow): guarantee all eligible photos shown + 2048px display derivative ... Diashow completeness rewrite so every eligible upload is shown regardless of bursts, disconnects, or library size: - queue.ts: SlideQueue with live/shuffle queues, allKnown map, recentlyShown ring; merge(dedup, live-first), remove/removeByUser (prunes recentlyShown), knownIds for reconcile-eviction. Adds queue.test.ts (burst/completeness/race). - diashow/+page.svelte: reconcile (full paginate + evict, pre-scan snapshot to spare concurrent uploads) on mount/reconnect/periodic; catchUpNew paginate- until-known for bursts with debounced maxWait; hard-cut removals; decode timeout + candidate fallback + bounded skip so a broken image never stalls. New ~2048px "display" derivative for big-screen sharpness, decoupled from the data-saver preview (800px) used on phones: - migration 016: upload.display_path + v_feed rebuilt (DROP+CREATE, not REPLACE, to slot the column beside preview/thumbnail). - compression: generate_image_derivatives emits preview+display (downscale-only guard, no upscaling); backfill_missing_display regenerates on startup (safe: logs on error, never soft-deletes). - upload.rs/main.rs: GET /upload/{id}/display (mirrors preview auth/cache), /media/displays direct-serve blocked. - feed.rs + types.ts: display_url in feed/delta DTOs. - diashow candidate chain: display -> original -> preview. Verified on the running stack: migration applied, 10/10 existing images backfilled (2048px cap honoured, small images not upscaled), /display serves 200, /feed returns display_url, diashow cycles.

MechaCat02	44641473ea	fix(quota): stop /me/quota leaking raw disk to guests ... The per-user quota widget was shown to everyone and the /me/quota payload returned free_disk_bytes (raw server free space) and active_uploaders to any authenticated guest. Gate the widget to staff (host/admin) on the upload and account pages, and zero the server-wide telemetry fields for non-staff in the handler. Guests still get their own used/limit so enforcement stays transparent. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-07-19 15:22:03 +02:00
MechaCat02	57a907eca5	feat(theme+comments): runtime colour theme and COMMENTS_ENABLED switch ... Colour theme is configurable at runtime from two seed colours (brand + accent); neutrals stay fixed for contrast safety. Tailwind v4 var()-based tokens let a :root:root override recolour everything with no rebuild; the 50->950 ramps are derived via a color-mix ladder. Config lives in the DB config table (admin UI: Config > Farbschema, presets + custom pickers + live preview), served on the public /event endpoint with env defaults (THEME_PRESET/PRIMARY/ACCENT), propagated live via event-updated SSE, and cached in localStorage for a no-flash boot. The keepsake export mirrors the same ladder in Rust so offline archives match the event theme. COMMENTS_ENABLED (env, default true) is a boot-time kill-switch: the backend rejects new comments with 403 and the frontend hides the comment button (feed card) and panel/composer (lightbox). Existing comments stay in the DB, hidden, and return when re-enabled. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-07-19 15:21:55 +02:00
MechaCat02	3c3a7d0082	fix(diashow): open SSE on mount; raise upload rate 10→100/hour ... diashow only subscribed to SSE events but never called connectSse(), so a kiosk/projector opening /diashow directly (not via /feed) never opened the EventSource — the showcase display got a one-time /feed snapshot and no live updates, showing "Noch keine Beiträge" forever when turned on before any photos. Open the stream in onMount (idempotent) and close it in onDestroy, mirroring the feed page. Raise the default upload_rate_per_hour from 10 to 100 (migration 015, scoped to installs still on the old default so admin overrides are preserved). Guests routinely upload bursts of 10-20 photos; the old default throttled the first burst. Also update the code fallback and the test-mode reseed. Both verified end-to-end against the docker test stack. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-07-18 17:29:08 +02:00
MechaCat02	3654aca18b	feat(export): single-file offline keepsake viewer + guest download ... Rebuild the guest "keepsake" (offline HTML gallery) so it renders when the extracted index.html is opened over file://. Browsers block external ES-module scripts and fetch() at origin null, so a normal multi-file SvelteKit build shows a blank window. Build the viewer as one self-contained index.html (inlined JS/CSS via vite-plugin-singlefile, standalone non-SvelteKit entry) and inject the data as window.__EXPORT_DATA__; the backend embeds the built viewer via include_dir! and writes the data global into index.html when zipping. Also surface the guest-facing download: a feed banner and the BottomNav Export tab, both shown once the host releases the export.

fabi	ee554e7f38	style(backend): rustfmt the whole tree; gate cargo fmt --check in CI ... The backend had never been run through rustfmt. Doing it in one mechanical pass (134 files) so no future functional diff is buried under formatting churn, then gating `cargo fmt --check` in checks.yml so it stays clean. Formatting only — no logic, SQL, or behaviour changed. Verified after the reformat: cargo test 56 passed, clippy --all-targets -D warnings clean, cargo fmt --check clean. This is the deferred cleanup noted when CI's Format step was first left out. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-07-15 19:52:17 +02:00
fabi	db7c4459d7	fix(upload): editing a caption after release now regenerates the keepsake ... edit_upload updated the caption/hashtags and nothing else. A caption lives in the HTML viewer keepsake (the ZIP holds media only — export.rs), so after release the downloadable viewer kept showing the OLD caption forever while the live feed showed the new one. Editing stays allowed while locked/released — like comments and likes, the lock freezes new uploads only (USER_JOURNEYS §9.3) — so the fix is to regenerate, not forbid: the edit and an invalidate_and_arm(ViewerOnly) share one transaction (same atomicity as delete_upload), then start_regen after commit. ViewerOnly carries the finished ZIP forward untouched since the media didn't change; when the gallery isn't released, invalidate_and_arm returns None and this is a no-op. Mutation-verified: without it, an edit doesn't bump the epoch and the caption test fails. Also (test isolation): the compression worker now carries a generation counter that TRUNCATE bumps. A worker queued on the concurrency semaphore when a truncate wiped media would otherwise wake in the NEXT test, fail to find its file, and broadcast upload-error/upload-deleted into that test's SSE stream — corrupting any test asserting on toasts or feed. It now abandons itself when the generation moved. No-op in production (TRUNCATE is the only caller). Export workers were already inert across a truncate (epoch guard on a fresh-UUID event).

fabi	d2ad560df2	test(security): prove admin-login rate limit; make its toggle settable ... The admin-login IP rate limit already existed (auth/handlers.rs: 5/min/IP, gated by `rate_limits_enabled` + `admin_login_rate_enabled`, both default true in prod) — the earlier "no rate-limit or lockout" note was wrong. What was missing was any TEST of it: the e2e reseed sets `rate_limits_enabled=false`, so the old test observed all-401 under a disabled limiter and "documented" the opposite of reality. Replace that test with three that enable the limiter and prove it, mutation-verified (deleting the check in the handler fails the first two): - a burst of wrong passwords from one IP starts returning 429 (first is a normal 401, so the password path ran and the limiter had budget; none is ever 200) - once throttled, even the CORRECT password is refused — isolates the RATE LIMIT from the password check (this is the assertion that dies if the limiter is removed) - with `admin_login_rate_enabled=false` the same burst is NOT limited (the toggle gates it) Two fixes this surfaced: - `admin_login_rate_enabled` and `recover_rate_enabled` are read by their handlers but were missing from patch_config's BOOL_KEYS allowlist — the switches existed in code and could never be flipped. Added both. - Test isolation: exhausting the admin-login limiter locks out the NEXT test's truncate fixture, which must itself call admin_login before it can reset anything. An afterEach disables the toggle via patchConfig (JWT-based, not rate-limited) so the next login is clear; truncate then wipes the counter map. Runs on failure too. Full desktop suite 201 passed / 1 skipped; backend 56 tests; clippy clean. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-07-15 19:10:41 +02:00
fabi	e5201a9889	test(backend): DB-backed tests for the risky SQL; test isolation; clippy cleanup ... All 40 backend tests were pure-function tests — not one line of SQL ran under `cargo test`, even though the riskiest code in the repo is SQL. Add 12 DB-backed `#[sqlx::test]` tests (fresh throwaway DB per test, real migrations) pinning the invariants that code is load-bearing for, each mutation-verified to fail on broken code: export_epoch.rs (8): epoch is post-increment on release (a worker born pre-increment is inert); epoch strictly monotonic across reopen; a retired-epoch worker's writes are no-ops; export_current is EXACTLY the invariant (8-case table); the ViewerOnly carry-forward carries a done ZIP forward AND matches nothing when the ZIP is unfinished (the af997a8 strand bug); boot recovery doesn't clobber a live ZIP. upload_concurrency.rs (4): the atomic quota UPDATE stops two stale-snapshot uploads from both committing (sequential AND concurrent-tx via EPQ); the FOR SHARE upload lock serializes against release, blocking a photo from committing after the export snapshot. Deleting FOR SHARE, or the carry-forward's `status='done'`, each makes a test fail. Test isolation: TRUNCATE now also resets disk_cache and sse_tickets. The stale disk reading was harmless only while quotas were globally off in e2e (they no longer are — see the new quota spec), i.e. two holes were masking each other. clippy: `cargo clippy --all-targets -- -D warnings` now passes (it did not). Deleted the dead jobs.rs (an unused BackgroundJob sketch) and unused model methods; `#[allow(dead_code)]` + comment on the sqlx FromRow field-sets that ARE populated by the DB. No SQL or logic changed. `cargo test` requires DATABASE_URL by design. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-07-15 07:26:08 +02:00
fabi	c229b560d8	fix(feed,host): two mis-tap bugs where a live re-render destroys the click target ... Both are the same class as the autocomplete bug fixed in bf68bc0: a handler must never destroy the DOM node that is being clicked. feed grid tiles: VirtualFeed keys tiles by upload.id but slices the uploads array POSITIONALLY (`uploads.slice(i*COLS, …)`). A `new-upload` SSE prepends to the array, so every tile shifts one slot and each row's keyed {#each} sees a new set of ids — Svelte destroys and recreates the tile nodes. At a party, where photos stream in continuously, a guest mid-tap can have the node torn out (tap swallowed) or, worse, like/open a DIFFERENT photo that slid under their finger. Grid now buffers live arrivals behind the existing "neue Beiträge" pill; list view is keyed at the top level and stays live. host rebuild button: it lived inside an SSE-driven {#if exportGenerating}{:else if exportReady}{:else} block, and rebuildExport() makes the backend broadcast export-progress immediately — so pressing it flipped the branch and unmounted the button mid-click, on the one screen whose purpose is recovering a broken keepsake. One button now stays mounted across all three states; only its label and disabled vary. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-07-15 07:25:19 +02:00
fabi	2bef6e19ef	fix(export): deleting a comment mid-build no longer strands the ZIP forever ... Found while auditing the test suite: the ViewerOnly carry-forward (added by me in 9666d74) permanently breaks the ZIP download if a comment is deleted while the ZIP is still being built. A comment-only change doesn't alter the ZIP's media, so `Affects::ViewerOnly` carries the finished archive into the new epoch rather than rebuilding it. But "finished" is a PRECONDITION, and between `release_gallery` and the ZIP worker completing it is false — for a real multi-GB gallery, for MINUTES. Deleting a comment in that window is an utterly ordinary thing to do. The carry-forward UPDATE is guarded on `status = 'done'`, so in that window it matched nothing — and ViewerOnly re-armed only the viewer. The ZIP row was left at the retired epoch; the in-flight worker finished and wrote `done` at an epoch `export_current` no longer matches. `GET /export/zip` then 404s FOREVER: recovery only runs at boot, and `release_gallery` refuses an already-released event. The guests' keepsake is simply gone, and the only escape is the rebuild button added one commit ago. Fix: the carry-forward's own `rows_affected()` decides. It matched => there is a current, finished ZIP and only the viewer needs rebuilding. It didn't => there is nothing to preserve, so rebuild the ZIP too, like any other invalidation. Never assume the precondition; ask the UPDATE. Proven non-vacuous: with the fix reverted the new test fails with the ZIP stranded at the retired epoch (job epoch 1, event epoch 2, export_current holding only "html", download 404). Backend 40 tests, e2e 163 passed / 1 skipped. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-07-14 22:50:17 +02:00
fabi	3c683247c0	chore(deploy): expose the export rebuild hatch in the UI; rehearse migration 014 ... Three deploy-readiness gaps, none of them in the export invariant itself. 1. The escape hatch was unreachable. `POST /host/export/rebuild` was added as the fix for "a failed export is terminal", but nothing in the frontend called it — so recovery required a terminal, the API docs and a valid JWT. The host page instead told the host to reopen uploads and re-release, which is the destructive act the endpoint exists to avoid (it unlocks the gallery to every guest and retracts the release). The failed state now offers "Erneut versuchen"; a ready keepsake can be rebuilt behind a confirm, since a rebuild makes it briefly undownloadable. 2. Migration 014 had never been run against anything. It is the repo's first destructive migration and its backfill has to carry the old notion of "downloadable" across exactly — get it wrong and a released event's keepsake silently 404s, on data that cannot be re-created. backend/scripts/rehearse-014.sh proves it on a throwaway postgres, against a real pg_dump or a synthetic DB covering every pre-014 state, asserting up, down and up-again all preserve downloadability. Verified non-vacuous: retiring nothing (ELSE -1 -> ELSE e.export_epoch) fails it, naming the three keepsakes it would resurrect. It also surfaced that the down migration is an inverse UP TO DRIFT: a ready flag that disagreed with its job row comes back FALSE. That heals corruption rather than restoring it, and costs nothing (no file_path to serve), so the assertion checks what actually matters — no genuinely downloadable keepsake loses its flag — and reports the normalisation instead of failing on it. 3. No advisory scanning. cargo audit + npm audit, in .github/workflows/ because Gitea Actions scans it too and e2e.yml already resolves actions/* from GitHub. The runner is not assumed to have cargo. RUSTSEC-2023-0071 (rsa/Marvin) is ignored SPECIFICALLY, not globally: it is unreachable here (HS256 + bcrypt, Postgres only) and unpatched, so failing on it would mean a permanently red pipeline everyone learns to ignore. Tests: e2e pins that a failed keepsake recovers via rebuild while the event stays released and uploads stay locked — so a future refactor implementing rebuild as an internal reopen+re-release fails — and that rebuild cannot publish an unreleased gallery.

fabi	9666d74a46	fix(export): close all 13 findings from the multi-agent review ... A 6-lens multi-agent review (103 agents; every finding adversarially verified by three refute-by-default skeptics) confirmed the epoch redesign is sound — the core invariant holds — and found 13 real defects around it. All are fixed here. The redesign's invariant was re-verified and stands: an accepted upload is always in the keepsake, and a downloadable keepsake always reflects the most recent release. But a WEAKER adjacent invariant did NOT hold — "a downloadable keepsake reflects the current content" — and that is the theme of the biggest fixes. CONTENT REMOVAL NOW ALWAYS REACHES THE KEEPSAKE Regeneration was wired only to host deletes. Ban, unban, guest self-delete and guest comment-delete did not trigger it — yet the export query filters `is_banned = FALSE`, so the pipeline already agreed that content must not be there. Ban someone for abusive content after release and every guest kept downloading an archive containing it. All five removal paths now invalidate and rebuild. `query_comments` also gained the banned/hidden filter it was missing entirely (the ZIP had it; the viewer did not). Each removal is now ATOMIC with its invalidation (one tx, models made executor-generic). Previously the delete committed in its own tx and the regeneration in a second: a dropped handler future between them left the taken-down photo permanently downloadable, and nothing could notice — the keepsake still looked complete and the host could no longer even find the upload to retry. NO MORE TAKEDOWN STORM Every removal spawned two uncancellable full exports. A superseded worker was INERT, not STOPPED: it still ran every ffmpeg spawn and image resize and wrote a whole archive before discovering it had lost. Five deletes left ten workers alive, each holding a full-gallery-sized temp, in a 1 GB container. Now: a debounce before `claim_job` (a superseded worker fails its claim and does ZERO work, collapsing a burst into one export), plus `update_progress` — which already ran exactly the right liveness predicate and threw the answer away — returning it so both file loops bail the instant they are retired. Moderating a comment no longer rebuilds the multi-GB ZIP either: the ZIP is media-only, so it is carried forward, with prune taught to protect any file a live row still references. AN ESCAPE HATCH A failed export was terminal at runtime: release_gallery refuses an already-released event, recovery only runs at boot, and there was no retry route — the only outs were restarting the container or reopening uploads to every guest. Added POST /host/export/rebuild. Also widened mark_failed's guard to `status IN ('running','pending')`: when claim_job itself ERRORED, the row was still `pending`, so the failure was never recorded and the job sat at 0% forever. SILENT INVALIDATION Retiring the epoch 404s the download instantly, but nothing told the clients — guests kept seeing an enabled download button through the whole rebuild. Now broadcasts an invalidation. And the download was a top-level <a href>: a 404 (or a 429 from the per-IP export limit that everyone on the venue WiFi shares) NAVIGATED THE USER OUT OF THE PWA onto raw JSON. It now targets a hidden iframe, so an error response is harmless. ALSO - The HTML export still had the exists()-then-open TOCTOU the ZIP path was fixed to remove, at three sites, two with a hard `?` that failed the ENTIRE viewer. It is reachable: the compression worker hard-deletes an original when a transcode fails and can still be running when the gallery is released. - Crash-orphaned .tmp files were immortal (prune deliberately skips .tmp). Swept at boot, where it is unambiguously safe. - export_status read the epoch in one statement and used it in the next; now one query. - DiskCache::snapshot IGNORED its path argument on a cache hit, returning whatever filesystem was measured last. Latent only because both callers pass media_path — it would have silently misreported the moment anyone measured the exports volume. Now keyed by path. - Corrected two comments that asserted safety properties the code does not have (claim_job does NOT prevent a retired-epoch claim — retirement is enforced at READ time; and a multi-replica reap is NOT contained, it can corrupt the keepsake). Added a rollback runbook to migration 014, the repo's first destructive migration. TESTS The regression guard for the headline FOR SHARE fix was probabilistic — it could pass on broken code if the interleaving fell the wrong way. It is now STRUCTURAL: the upload is held open mid-body with its pre-flight check already passed, so the release provably lands inside the exact window. Verified 5/5 FAILING (201 instead of 403) with the fix reverted, 5/5 passing with it. Verified: backend 40 tests, svelte-check 0 errors, e2e typecheck clean, e2e 160 passed / 1 skipped on chromium-desktop.

fabi	8e906d7866	refactor(export): single epoch authority; fix upload-path TOCTOU losing photos ... A deep investigative review of the export concurrency (four parallel adversarial reviewers) found that three rounds of race fixes had been chasing the wrong bug, and that the model itself was the root cause. This replaces the model and fixes the real data loss. THE ACTUAL BUG (upload path, not the state machine) `upload` checked `uploads_locked_at` BEFORE streaming the body — minutes, for a large video — then committed the row without re-checking. A release landing mid-upload let the row commit AFTER the export snapshot: the photo appeared in the live feed and was PERMANENTLY missing from the keepsake, with nothing to regenerate it. release_gallery's comment claims to prevent exactly this; it never did. Every prior round fixed the DB state machine, and the leak was upstream of it. Fix: re-assert the lock under `SELECT ... FOR SHARE` INSIDE the commit tx. That row lock conflicts with release_gallery's `UPDATE event`, so either the upload commits first (and the release — hence the snapshot — is ordered after it) or the release wins and the upload is rejected as `uploads_locked` (reversible; the client keeps the blob). Regression test verified NON-VACUOUS: with the fix reverted it fails, reporting accepted uploads missing from the keepsake. THE MODEL (migration 014) "Which generation is current?" had no single answer: it was assembled from three separately-written pieces across two tables (`export_released_at`, a per-job `release_seq`, and cached `export_{zip,html}_ready` flags). Keeping them in agreement took ~10 hand-written guards; each review round found one more path that slipped through. Now: ONE monotonic `event.export_epoch`, bumped in the same UPDATE as any change to `export_released_at`. Each job carries a copy. Downloadable IFF `released AND job.epoch = event.export_epoch AND status = 'done'` — readiness DERIVED, never stored. A retired-epoch worker is INERT BY CONSTRUCTION: losing a race can no longer corrupt state, only waste work. Deleted: both ready-flag columns, both ready-flip blocks, `if ready { continue }`, the reopen seq-bump, open_event's transaction, and the cross-table claim guard. That last one was also UNSOUND: under READ COMMITTED, a blocked UPDATE re-evaluates its WHERE against the updated target row but answers subqueries on OTHER tables from the original snapshot — so the previous `EXISTS (SELECT ... FROM event ...)` claim guard could admit a claim against an already-reopened event while RETURNING the post-bump seq. Every guard is now same-row (`epoch = $n`), which EPQ re-evaluates correctly. OTHER REAL DEFECTS FIXED - release_gallery committed the release and THEN awaited the enqueue inside the handler future. Axum drops that future on client disconnect → event released, uploads locked, ZERO export_job rows, host unable to retry ("bereits freigegeben"), restart-only recovery. Now one tx; workers spawn (detached) after commit. - No flush/fsync before the tmp→final rename. async_zip's close() never flushes the inner file and tokio's File drop DISCARDS write errors — so a full disk silently produced a truncated archive that was then marked done and published, after which the last good generation was pruned. Now flush + sync_all, which also surfaces ENOSPC. - Download read the ready flag and the file path in TWO queries; a reopen between them served a keepsake that should 404. Now one read through the `export_current` view. - `if !src.exists() { continue }` then `open()?` — a TOCTOU that turned a tolerated gap into a hard failure of the ENTIRE keepsake (unretryable while released). Now open-first, warn, and skip. - Recovery was flag-driven and never checked the disk: a `done` row whose archive was gone was a permanent dead end needing manual DB surgery. Now verifies the file and re-arms. - Temp files/dirs leaked on every error path (the leak is what fills the disk that corrupts the next archive). Now cleaned up. - Export archives were not event-scoped (`viewer_tmp_` already was), so a second event would collide on paths and one event's prune would delete another's live keepsake. - Host deletes after release never regenerated the keepsake — a photo removed on request lived on in the archive forever. Now bumps the epoch and rebuilds without it. - claim_job swallowed DB errors as "someone else won", stranding a job pending at 0%. - export_status reported retired-epoch rows (a progress bar that never moves). - The startup sweep's single-instance assumption is now documented, not hidden. Verified: backend 40 tests, svelte-check 0 errors, e2e typecheck clean, e2e 160 passed / 1 skipped on chromium-desktop (incl. 2 new regressions; the upload-acceptance one confirmed to fail without the fix).

fabi	9f3712894d	fix(export): pin export workers to a live release epoch; make reopen atomic ... Adversarial re-review of c197b2c found the previous fix both incomplete AND that it introduced a new stuck-state regression. Two independent reviewers flagged the latter. HIGH (data loss, still open after the last fix) — a worker could claim a LIVE seq after a reopen. `claim_job` took any `pending` row. If a reopen landed between `release_gallery`'s spawn and the worker's claim, the row was left pending at the *bumped* seq, so the worker claimed a CURRENT generation and spent minutes exporting a snapshot taken while the event was open and guests were still uploading. On the next re-release (which re-arms `export_released_at` BEFORE it bumps the seq) that worker's finalize and ready-flip both passed their guards, flipped ready on its stale snapshot, and made `enqueue_and_spawn_exports` skip regeneration — silently serving a keepsake missing every upload from the reopen window. The reopen seq-bump did not help: the worker's seq was not stale. Fix: `claim_job` now refuses to claim unless the event is still released. A worker's generation is therefore always born AND finalized inside a single live release epoch. The unclaimed pending row is harmless — the next release resets and re-spawns it. HIGH (regression I introduced in c197b2c) — `open_event`'s event-UPDATE and its export_job seq-bump were two autocommit statements. The first is exactly what re-enables `release_gallery`, so a re-release could slip between them: it spawns a FRESH worker at seq N+1, then our second statement bumps that live generation to N+2, orphaning the worker. Its seq-guarded finalize/fail/flip then all match nothing, the row is stranded `running` with no owner, and the host cannot retry ("bereits freigegeben") — only a process restart recovers it. Fix: both statements now run in one transaction, so the row lock on `event` serializes `release_gallery` behind the commit. LOW - The flip-lost path left its stale archive on disk (asymmetric with the finalize-lost path, which deletes it). If a host reopened and never re-released, no future generation would ever prune it. Now discards `out_path` and still sweeps older gens. - A reopen clears the ready flags server-side, but nothing told the clients: the nav and /export page kept advertising a keepsake that now 404s. Both now refresh on `event-opened` (a superseded worker deliberately emits no `export-progress`). Tests - New: a release broadcasts `export-progress` 100 for both types + one `export-available`. The export SSE had ZERO e2e coverage, and this round made the emit conditional — `/export/status` polling reads the job row, not the SSE, so a regression here would have left every other test green while the live UI silently stopped updating. - New: open ‖ release churn always converges to a consistent, downloadable keepsake. Honestly labelled a STRESS test, not a regression guard: verified it still passes against a deliberately non-transactional build even with ~90 concurrent pairs, so it does NOT cover the atomicity fix (that window is not reproducible out-of-process). - Verified the reopen-supersession test is non-vacuous by empirically reverting the seq-bump — it fails, as intended. Verified: backend 40 tests, svelte-check 0 errors, e2e typecheck clean, e2e 158 passed / 1 skipped on chromium-desktop.

fabi	d643256f36	fix(rereview): close residual export finalize↔flip double-race at reopen ... Adversarial re-review of df275bb found the two-guard ready-flip fix still left a narrow double-race open, plus test-hygiene drift from the banUser param removal. MED — residual stale-keepsake race the `export_released_at` guard alone missed The flip relied on two guards defeating two clearers: the `release_seq` EXISTS check (vs a re-release bump) and `export_released_at IS NOT NULL` (vs open_event's clear). But release_gallery re-arms `export_released_at = NOW()` and bumps `release_seq` as SEPARATE statements, so a stale worker's flip landing in the gap between them satisfies BOTH guards (released re-armed, seq not yet bumped) and resurrects a pre-reopen keepsake — the next re-release then skips regeneration and serves an archive missing the reopen-window uploads. Root-cause fix: `open_event` now bumps every `export_job.release_seq`, making a reopen a supersession point symmetric with a re-release. A worker that captured the pre-reopen seq can never match its `release_seq`-guarded finalize/flip again, regardless of when the re-release re-arms `export_released_at`. The released-anchor guard stays as defense-in-depth. Added a deterministic e2e asserting the reopen bumps the seq (the invariant that closes the race without depending on sub-millisecond worker timing). LOW - Gate the `export-progress: 100` SSE + `prune_stale_export_files` on the ready-flip actually flipping (rows_affected > 0). A superseded worker no longer advertises a misleading 100% or prunes on a fresh generation's behalf. - moderation.spec.ts: the two ban tests had become byte-identical after the hide_uploads param removal; drop the one whose "hide_uploads=true" title no longer matched what it exercised, keep the accurate "always hides" test. - host-dashboard page-object: drop the dead `banUser(hideUploads)` param + its checkbox branch (the UI no longer renders that checkbox — a latent hang trap). - sse-eviction.spec.ts: rename the test whose title referenced the removed flag. Verified: backend 40 tests, e2e 156 passed / 1 skipped on chromium-desktop (incl. the new reopen-supersession regression).

fabi	df275bbefa	fix(rereview): close export-flip race + queue-dedup reload regression ... Adversarial re-review of the persona-audit + audit-followup rounds (6411747..) found one HIGH and one MED regression plus LOW gaps. All fixed with coverage. HIGH — export stale-keepsake resurrected by an open_event race A reopen landing in the window between a *current* export worker's finalize_job and its ready-flag flip cleared export_released_at + the ready flags but left the export_job row `done` at the same release_seq. The seq-guarded flip then still matched and re-set export_{zip,html}_ready=TRUE on a pre-reopen snapshot; the next re-release read that stale TRUE and skipped regeneration (`if ready { continue }`), serving a keepsake missing every upload from the reopen window — the exact data loss migration 012 exists to prevent. Both ready-flip UPDATEs are now additionally anchored on `export_released_at IS NOT NULL`, so a landed reopen makes the flip a no-op and the re-release regenerates cleanly. MED — queue dedup broke for reloaded items loadQueue rebuilt QueueItems from IndexedDB without copying lastModified, which the new addToQueue dedup keys on. A file re-selected after a page reload / PWA relaunch missed the duplicate check and uploaded twice. Rehydration now carries lastModified (extracted to a pure, tested entryToQueueItem helper). LOW - diashow: clear the upload-processed debounce timer in onDestroy (no stray post-unmount /feed fetch). - USER_JOURNEYS §9.5: document the reconnect-delta ban replay (hidden_user_ids / uploads_hidden_at, migration 013), not just the live user-hidden SSE. - e2e api-client: drop the misleading hide_uploads param from banUser — the backend takes no body and always hides; strip the dead boolean at all call sites. Tests - Extract isReversibleLock (the terminal-403 KEEP-vs-PURGE-blob discriminator) into a pure exported helper + unit tests, so the data-loss-critical branch is covered without an XHR harness. - entryToQueueItem unit tests lock the lastModified-carry regression. - Document the export flip-race guard in the reopen/re-release spec (the sub-ms finalize↔flip interleave isn't deterministically forceable with fast fixtures; covered by the SQL guard + the end-to-end completeness test). Verified: backend 40 tests, frontend 44 unit tests, svelte-check 0 errors, e2e 156 passed / 1 skipped on chromium-desktop.

fabi	36fe59caa5	fix(user-flow): persona-audit fixes — ban replay, locked-upload data loss, host UX, admin session ... Follows the perf + security + user-flow work with a role/persona audit (guest, host, admin, projector) and fixes across three review rounds. Highlights: HIGH - Ban now replays on reconnect. A ban isn't a soft-delete, and the `user-hidden` SSE has no replay, so a client that missed it (esp. the unattended diashow) kept cycling a banned user's slides. New `uploads_hidden_at` (migration 013) + `hidden_user_ids` in /feed/delta; feed + diashow evict those users. Applied even on a truncated delta. MEDIUM - Locked-upload data loss: a photo staged offline during a lock/release was purged as a terminal 4xx and lost when the host reopened. New reversible `uploads_locked` error code; the queue keeps the blob and auto-resumes on the `event-opened` SSE. - Reopen after release now warns (ConfirmSheet) that it revokes the published keepsake. - Host "forgotten-PIN" badge updates live (`pin-reset-requested` was broadcast but never in KNOWN_EVENTS / subscribed); host page also refetches on `pin-reset` so a two-host race can't hand out a conflicting PIN. - Ban modal copy fixed (read-only ban, not "session ended"); Degradieren/Sperren/Entsperren hidden on peer-host rows for non-admins (they always 403'd). - Host dashboard shows live keepsake generation progress / ready state + link to /export. - Admin JWT moved to sessionStorage (§11.1) to bound exposure on shared devices. Export generation guard (H1 from the prior round, hardened): per-(event,type) `release_seq` (migration 012) with seq-guarded claim/finalize/mark_failed/update_progress, per-generation temp/final paths, download follows `file_path`, prune only strictly-older generations. LOW: diashow coalesces upload-processed (avoids self-rate-limit); event-closed reconciles galleryReleased; /recover gains a forgot-PIN request + drops a stale cached PIN on 401; delta `>=` tie-break + 429 retry; misc copy/labels. Adds e2e: ban-replay, upload-lock-code, and rewrites export-reopen-rerelease with a data-completeness test. Reconciles USER_JOURNEYS §9/§11. Verified: cargo build clean, 40 unit tests, svelte-check 0 errors, 33 frontend unit tests, 155 e2e passing on chromium-desktop.

MechaCat02	641174717c	fix(user-flow): close offline-queue, export, session, ban & realtime gaps ... 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.

fabi	a4b2c5bd1c	fix(security): harden authz, media gating, recover, SSE, deps ... Security audit follow-up. No Critical/High existed; these close the Medium/Low findings. F1 [Med] Host privilege boundary: a host could demote a peer host to guest and then ban / PIN-reset (→ account takeover via /recover) them, because the ban/pin-reset peer guards key off the target's *current* role. set_role now blocks a non-admin from demoting a host. F2 [Med] Moderation now revokes preview/thumbnail access: they are served through visibility-checked aliases (/api/v1/upload/{id}/{preview, thumbnail}) that filter soft-deleted / ban-hidden uploads, and direct /media/previews|thumbnails is 404-blocked. Feed emits the gated URLs; Caddy keeps them privately cacheable (max-age=300, short so moderation revokes promptly — the live feed already evicts cards via SSE). Uses a lean find_visible_media() (paths+mime only) on the media hot path. F3 [Med/Low] npm audit fix: svelte 5.55.1→5.56.4 (SSR-XSS advisories), devalue 5.6.4→5.8.1 (DoS). Prod deps: 0 vulnerabilities. F4 [Low] /recover no longer leaks account existence: unknown display name returns the same 401 as a wrong PIN, and runs a dummy bcrypt verify so timing matches — closing the enumeration + timing oracle. F5 [Low] SSE streams re-validate the session every ~60s and close once it is logged out / expired, instead of running until client disconnect. F6 [Info] X-Content-Type-Options: nosniff set at the app layer on all media responses (defense-in-depth alongside the edge). Tests: new e2e specs for F1 (host cannot demote peer host), F2 (preview gated + 404 after delete + direct /media blocked), F4 (uniform 401). 40 backend unit tests + 182 e2e passing.

fabi	d6c91974eb	perf(backend): close config/upload/export hot paths + stability fixes ... Performance: - Cache the runtime `config` table in-memory (ConfigCache) with synchronous invalidation on every write (admin PATCH + test reseed). Was re-reading each key from Postgres on every request (~8 round-trips per upload). - Stream uploads chunk-by-chunk to a temp file instead of buffering the whole body in RAM (peak was up to the per-class cap, e.g. 500 MB/video); only 512 sniff-bytes are kept for magic-byte detection, then atomic rename into place. - Cache the media-filesystem disk snapshot (DiskCache, 15s TTL) shared by the quota check and admin stats; drop the discarded System::refresh_all(). - HTML export streams video (and small-image) originals straight into the ZIP via a manifest instead of copying them to a temp dir first (removed the transient 2x disk usage) and drops the double directory scan. - Auth extractor resolves session -> live user in one JOIN (was two queries), touching last_seen_at by token hash. Stability: - SSE: on broadcast lag, emit a `resync` event so the client runs a delta fetch instead of silently losing events; frontend reconciles adds, deletions, and (via an in-place refresh) like/comment counts on visible cards. - Storage quota fails OPEN when the disk can't be read (was a 0-byte limit that locked out all uploads). - Graceful shutdown drains in-flight requests on SIGTERM/SIGINT, bounded by a 10s backstop so open SSE streams can't stall a deploy. - Upload removes the persisted file if the DB transaction fails (no orphaned bytes with no row to reclaim them). Tests: - New pure select_disk() with 5 unit tests (longest-prefix, fallbacks, fail-open). - New e2e export-video spec covering the HTML export's video-streaming branch.

fabi	faf7a2504a	fix(audit): restore broken upload pipeline + role-based E2E audit fixes ... A comprehensive role-based E2E audit (guest/host/admin, across browser sessions) surfaced one critical and several smaller issues; this addresses them and hardens the tests that missed them. Critical - The client upload pipeline was fully broken: the IndexedDB v1->v2 upgrade opened a *new* transaction inside the upgrade callback, which throws during a version-change transaction and aborted the whole upgrade, leaving the queue object store uncreated -- so no UI upload ever fired. Reuse the version-change transaction the callback provides, and bump the DB to v3 with a contains() guard so installs already corrupted by the shipped bug self-heal on next load. Re-enabled the previously-fixme'd UI upload E2E test. High / Medium - Event lock is uploads-only again: likes, comments and browsing stay open while the event is locked (USER_JOURNEYS 9.3 / FEATURES) -- it was wrongly freezing social interaction. Updated the event-lock spec accordingly. - get_original now excludes soft-deleted and ban-hidden uploads, and direct /media/originals/** serving is blocked, so a hidden user's originals can no longer be pulled by UUID (all originals go through the checked alias). - The upload handler reads the file field with an early-abort size cap chosen from the declared content-type, instead of buffering the entire body before the size check. Low - unban_user mirrors the ban role guard (a host can no longer unban a host/admin banned by an admin). - reset_user_pin's UPDATE is event-scoped. - Admin login returns and stores a real identity (user_id + display name) instead of a blank session. - The host user list no longer renders target-actions (ban/promote/demote/PIN) on the caller's own row, where the backend always rejected them. - /diashow gains a client-side auth guard like the other protected routes. - The join page shows the event name via a new public GET /api/v1/event. Verified: backend cargo build clean, frontend svelte-check 0 errors, full Playwright E2E suite 144 passed / 1 skipped.

fabi	3f6dafba05	test(review-2): strengthen CR2 export-leak test to drive a real export ... The prior test asserted 404 on /media/exports/Gallery.zip against an empty stack — it would pass even if exports were still written under /media, because no archive was ever produced. Now it: 1. seeds an upload, releases the gallery, and polls until the real zip job writes Gallery.zip to disk; 2. asserts the archive is NOT served from public /media (the CR2 leak); and 3. asserts it IS retrievable via the gated ticket endpoint (200 + PK zip magic) — proving the 404 means "not public", not "no file". Also fixes a test-isolation gap the CR2 relocation introduced: __truncate wiped media_path but not export_path, so a real export would leave Gallery.zip on disk and break export.spec's "ready-but-file-missing → 404" test. truncate_all now purges export_path too. Full 06-export dir: 5/5 green, no contamination. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-07-03 07:19:09 +02:00
fabi	0ed97f45cf	fix(review-2): address re-review — close two blocker regressions + harden tests ... The round-2 re-review (full suite green) found two real defects the passing tests missed, both now fixed and covered: B1 — banned users could still edit/delete their OWN content: edit_upload, delete_upload, delete_comment skipped the is_banned guard that upload/ like/comment got (round-2 removed the global extractor block and missed these three). Added the guard (using auth.is_banned — no extra query). The moderation ban test now asserts 403 on DELETE upload, PATCH upload, and DELETE comment for a banned owner (+ upload survives) — it previously only exercised POST /upload, which is why the gap shipped green. B2 — H3 live-eviction was dead code: 'user-hidden' and 'comment-deleted' were missing from KNOWN_EVENTS, so EventSource never listened and the handlers never fired. Added both. New browser-driven sse-eviction test asserts a hidden user's card actually evicts from an open feed with no reload — the backend-only SseListener checks couldn't catch this. Minor items folded in: - admin dashboard bounces a mid-session-demoted admin to /feed via live /me/context (mirrors the host page) instead of a dead error screen. - feed "new posts" pill cleared on any full refresh (pull-to-refresh no longer strands it). - corrected the stale sse.rs comment (banned users may hold a read-only stream). Verified: backend 35 unit tests; svelte-check 0 errors; e2e 04-host + comment-ui + export-leak 13/13 on chromium (incl. the two new regression tests).

fabi	b3d876fa85	fix(review-2): medium/low + docs — config validation, hygiene, doc sync ... - compression_concurrency wired to boot config (state.rs) and removed as a dead admin control. - patch_config gains per-key integer/range validation so numerically-valid-but- nonsensical values (-1/NaN/3.5) are rejected instead of silently reverting to default at read time. - clearAuth now also clears the display name (shared-device residual). - e2e/Caddyfile.test mirrors prod security headers + the SSE encode-exclusion so the test stack is representative and can catch header regressions. - .gitignore: ignore root-level Playwright artifacts (test-results/, report). - docs: USER_JOURNEYS §10 and SECURITY-BACKLOG updated to match the implemented read-only-ban behavior and the export-path fix.

fabi	80179357a7	fix(review-2): high — read-only ban model, failed-compression cleanup, live SSE eviction ... H1: corrected a round-1 over-reach. Bans are read-only per USER_JOURNEYS §10: the base AuthUser extractor no longer rejects banned users (they keep read access); Require{Host,Admin} and write handlers enforce the ban via auth.is_banned → 403 (incl. self-unban). Demoted hosts still lose powers immediately (live DB role) and are bounced off the dashboard. Also fixed the login/recover redirect regression on unauthenticated 401. H2: failed compression now self-heals instead of leaving a permanent broken card — refund the quota, delete the orphaned original, soft-delete the row; the frontend toasts the uploader and evicts the card on upload-error. H3: self-delete, ban-with-hide (user-hidden), and comment-deletes now broadcast SSE; feed, diashow, and lightbox evict the affected content live instead of waiting for a reload. sse-eviction.spec.ts covers it. Riders: feed/+page.svelte also carries the medium truncated-delta pill; host.rs also carries the low atomic release_gallery claim; admin/+page.svelte also drops the dead compression_concurrency control (medium).

fabi	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).

fabi	41ac742af8	test+docs: tighten H1 assertions, cover secret/XFF edges, document boot & SSE-ban ... Re-review follow-ups (non-blocking quality items): Tests: - moderation H1 specs now assert exact `→ 403` instead of bare .rejects.toThrow(), so a spurious 500 can no longer masquerade as "revocation worked". - config: added case-insensitivity (upper/mixed-case placeholder) and the len==32/31 boundary cases for validate_secrets. - rate_limiter: added the trailing-comma empty-entry case for client_ip (must fall back, not return ""). (Backend unit tests: 35 pass.) Docs: - README: note that with APP_ENV=production a placeholder .env makes the app refuse to boot and Caddy wait unhealthy — reason is in `docker compose logs app`. - SECURITY-BACKLOG + sse.rs comment: document that a mid-session ban does not tear down an already-open SSE stream (new tickets are blocked; low blast radius).

fabi	a084ba86c5	fix(review): CSP nonce for FOUC script + feed_delta truncation signal ... Two items surfaced by the branch re-review: CSP regression (blocking): script-src 'self' blocked the template-authored anti-FOUC theme script in app.html — SvelteKit's mode:'auto' only hashes scripts it injects. Added nonce="%sveltekit.nonce%" so it's substituted per request and included in the CSP (survives future edits, unlike a pinned hash). Verified: emitted CSP nonce matches the script tag; no violation, no flash. feed_delta silent truncation: the LIMIT 200 (added earlier to kill the stale-`since` DoS) returned only the newest slice with no signal, so a client that missed 200+ uploads during a reconnect could not tell it should full- refresh — the older missed uploads were dropped and unrecoverable (the next delta advances `since` past them). DeltaResponse now carries `truncated`; the feed's feed-delta handler calls loadFeed(true) to resync from page 1 instead of merging a partial slice. Verified: cargo check clean, svelte-check 0 errors, production build green. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-07-01 21:51:08 +02:00
fabi	91ff961850	fix(security): medium/low — event-lock, atomic config, a11y, diashow, hygiene ... - social: likes/comments rejected on a closed event (e2e proven). - admin: patch_config validates-then-writes atomically; char-based length. - hashtag/comment models: atomic tag writes in edit + comment paths. - Modal: inert the background (modal-inert action) for screen readers. - sse.ts: idempotent visibilitychange listener (no duplicate reconnects). - diashow: videos advance on `ended` (transitions + page wiring). - docs/hygiene: README clone-case fix; removed stale committed .env.test and gitignored it; docker-compose.dev.yml tidy. Left documented as accepted-risk per plan: PIN-persist-after-logout, UUID-reachable hidden uploads, DECISION-media-auth.md.

fabi	f08d858281	fix(security): high — live authz, XFF, SSE buffering, atomicity, pagination ... 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. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-07-01 21:25:50 +02:00
fabi	498b4e256b	fix(security): critical — repair PIN reset + enforce real prod secrets ... C1: reset_user_pin wrote to a non-existent column (pin_failed_attempts); the real column is failed_pin_attempts, so every PIN reset 500'd. Fixed the column name; new e2e (pin-reset.spec.ts) proves a reset returns a usable PIN and the target can recover with it. C2: config.rs::validate_secrets now rejects placeholder-ish secrets (change_me/dev_secret/placeholder), enforces len>=32 in prod, and requires a real ADMIN_PASSWORD_HASH. docker-compose.yml sets APP_ENV=production so the guard actually runs. Corrected the false "fixed" claim in SECURITY-BACKLOG.md. .env.example documents the rule. Riders in these files (documented here since git can't split hunks): - host.rs also carries the event-scoped ban_user fix and the close_event/open_event no-op broadcast guard (medium). - docker-compose.yml also adds ORIGIN (H6), app/frontend healthchecks with Caddy waiting on health, and per-service memory limits (medium).

fabi	226e455328	test(unit): broaden coverage — quota formula + auth token/JWT decode ... Backend: extract the per-user quota formula from compute_storage_quota into a pure `quota_limit_bytes(free_disk, tolerance, active)` (behavior-preserving) and unit-test it: tolerance scaling, floor of fractional results, active<1 clamped to 1 (divide-by-zero guard), zero free disk, single-uploader identity. Frontend (jsdom + browser:true mock): auth.ts token storage and JWT claim decode — setAuth/getToken/getPin round-trip, clearAuth keeps the PIN (for recovery), clearPin, getExpiry (exp seconds→ms Date; null on missing/malformed), getRole (role claim; null on absent/malformed). Adds jsdom devDependency. Backend: 25 passing. Frontend: 18 passing. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-07-01 19:53:03 +02:00
fabi	723a492d44	test(unit): add a unit-test layer (backend cargo + frontend vitest) ... 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. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-07-01 19:14:33 +02:00
