Layer 2 — remediate a corrupt file by re-fetching a fresh copy from its
source, bounded to a single attempt. Operator-requested 2026-05-28.
New backend/app/services/refetch_service.py:
- resolve_refetch_source: parse the failed file's sidecar → platform,
derive the artist from the import path, find an ENABLED Source with a
real feed URL for (artist, platform). Returns None for filesystem-only
imports, missing sidecars, or `sidecar:<platform>:<slug>` synthetic
anchors (not pollable).
- attempt_refetch: if not already refetched AND a Source resolves,
delete the corrupt file (so gallery-dl's skip_existing re-fetches it),
set ImportTask.refetched=True, and trigger ONE download_source
re-check. Bounded by `refetched` so source-side corruption can't loop.
Wiring:
- Manual endpoint POST /api/import/tasks/<id>/refetch (only on 'failed'
tasks). Returns refetch_queued / no_source / already_refetched /
not_found / not_failed.
- Auto path in recover_interrupted_tasks: for each poison-pill row, if
env FC_AUTO_REFETCH_CORRUPT=1, attempt_refetch (default OFF — the
manual button is the primary path; auto is opt-in since re-fetch
deletes a file + re-runs the downloader).
- Frontend: a cloud-refresh icon button on failed rows in ImportTaskList
→ stores.import.refetchTask → toast keyed on the result status.
Filesystem imports with no upstream return no_source — the operator's
only remediation there is replacing the file on disk, surfaced clearly
in the toast.
Tests: 404 unknown task, 400 non-failed task, no_source when
unresolvable, and the full resolvable-source path (file deleted,
refetched flag set, one download_source dispatched, second call is a
no-op). The resolvable test repoints the migration-seeded
import_settings(id=1) scan path rather than inserting a conflicting row.
Layer 3 — prevent the hard worker crash rather than just recovering from
it. The realistic process-crash vectors (operator's observed slow/heavy
tasks) are video decode and archive extraction; images decode in-process
and Pillow raises-and-skips cleanly, and a subprocess per image would
wreck deep-scan throughput, so images are intentionally not probed.
New backend/app/utils/safe_probe.py (leaf module, lazy heavy imports so
the spawned child stays light):
- probe_video(path): validates the container + first video stream via
ffprobe (a separate binary — a decoder crash kills only ffprobe, not
the worker). Returns width/height, which the importer didn't capture
for videos before. crashed=True only on ffprobe timeout.
- probe_archive(path): an uncompressed-size bomb guard
(MAX_ARCHIVE_UNCOMPRESSED_BYTES = 4 GiB) plus the format integrity
test (zipfile.testzip / rarfile.testrar / py7zr.test) run in a
spawned child process. A decompression-bomb OOM or native-lib
segfault on a malformed archive shows up as a non-zero child exit
code → crashed=True, never a dead worker.
ProbeResult.crashed distinguishes a HARD failure (subprocess killed /
timed out — the poison-pill signature → caller returns terminal
'failed') from a CLEAN rejection (corrupt-but-handled, bomb cap,
integrity mismatch → caller's choice of skipped/attached).
Wired:
- importer._import_media video branch: probe_video before the pipeline;
crash → failed, clean reject → invalid_image skip, ok → capture dims.
- importer._import_archive: probe_archive before extract_archive; crash
→ failed, clean reject → still preserve the archive as a
PostAttachment (matches extract_archive's fail-soft contract).
- ml.tag_and_embed video branch: probe_video before sampling 10 frames,
so a corrupt video is rejected (status='bad_video') instead of
crashing the ml-worker on frame decode.
Tests (test_safe_probe.py): valid/corrupt zip via probe_archive, direct
_inspect_archive size+integrity, in-process _archive_probe_target bomb
guard (monkeypatch can't reach a spawned child, so the target is called
directly), and a non-video → ok=False that's robust to ffprobe presence
in CI.
Layer 1 of the import-task resilience work (operator-requested
2026-05-28). The recover_interrupted_tasks sweep re-queues rows stuck
in 'processing' — correct for a worker crash, but without a cap a row
that RELIABLY hard-crashes the worker (OOM/segfault/SIGKILL on a
corrupt or oversized input) loops forever: re-queue → crash → re-queue,
burning a worker slot every 5 min. A caught exception flips to terminal
'failed' and never enters this loop; only process-killing inputs do.
- alembic 0026: import_task.recovery_count (int, default 0) +
import_task.refetched (bool, default false — backs Layer 2).
- recover_interrupted_tasks now runs a poison-pill UPDATE FIRST: stuck
rows whose recovery_count has already reached MAX_RECOVERY_ATTEMPTS-1
are marked 'failed' with a diagnostic ("crashed or stalled the worker
N times … likely a corrupt or oversized input … inspect/replace the
file, then retry via /api/import/retry-failed") instead of re-queued.
The re-queue pass then handles the remaining stuck rows and bumps
recovery_count. Shared stuck_predicate (and_/or_) keeps the
media-5min / archive-40min split.
- MAX_RECOVERY_ATTEMPTS=3 (two recoveries then give up).
The failed poison pill surfaces in the existing import-failures view
with its file path, directly answering "help me identify them."
Test test_recover_interrupted_poison_pill_caps_at_max pins both
branches: a row at the cap is failed (not re-enqueued, diagnostic
present), a row one short is re-queued + incremented.
Operator-flagged 2026-05-28: import_media_file on target 1645019 hit
SoftTimeLimitExceeded at exactly 5.0 min. Their diagnosis was correct —
the timeout covered the WHOLE archive, not per object. Importer._import_archive
(importer.py:409) runs the full per-member pipeline (sha256 + pHash +
dedup query + copy + provenance) for EVERY media member inline, all
under import_media_file's single 300s soft limit. A single media file
is sub-second; a multi-hundred-member archive blows the budget. They
shared one task name and one timeout.
**Split archive into its own task**
- New `import_archive_file` task: same body as import_media_file
(dispatch is by file-kind inside Importer.import_one) but
soft=30min / hard=35min. Shared `_run_import_task` helper holds the
flip-to-processing + resilience-contract wrapper; both tasks call it.
- New `enqueue_import(task_id, task_type)` router — single source of
truth for media-vs-archive dispatch. Used by all three enqueue sites:
scan_directory, /api/import/retry-failed, recover_interrupted_tasks.
- scan_directory now sets ImportTask.task_type = "archive" when
is_archive(entry) (the model field already existed, anticipating
this; scan was hardcoding "media").
- import_archive_file routes to the existing 'import' queue via the
task_routes `import_file.*` wildcard — no worker config change.
**Archive-aware recovery sweeps**
Both sweeps would otherwise preempt a legitimately-running archive:
- recover_interrupted_tasks (ImportTask 'processing' sweep): now
task-type-aware. Media stays at STUCK_THRESHOLD_MINUTES (5); archives
get ARCHIVE_STUCK_THRESHOLD_MINUTES (40 = 5-min buffer past the
35-min hard limit). Single UPDATE with an OR predicate over the two
(task_type, cutoff) pairs; requeue routes via enqueue_import.
- recover_stalled_task_runs (TaskRun 'running' sweep): now supports
per-task-name overrides (TASK_STUCK_THRESHOLD_MINUTES) layered above
the per-queue overrides added for ml. import_archive_file gets 40 min
while the 'import' queue stays at the 5-min default for single-file
imports. Precedence: task_name → queue → default, each pass excluding
rows claimed by a higher-precedence pass so every row is touched once.
**Tests**
- test_import_archive_file_registered
- test_recover_stalled_task_runs_archive_task_uses_longer_threshold —
pins that a 10-min archive task-run survives, a 50-min one is flagged,
and a same-queue 10-min media import is flagged at the default.
- _make_task_run gains queue= + task_name= params.
After deploy: archive imports get a 30-min budget and aren't preempted
by either sweep; single-file imports keep their tight 5-min detection.
Operator-flagged 2026-05-28: tag_and_embed on image 6288 (an mp4) was
marked failed by recover_stalled_task_runs at the 5-min sweep tick
while still legitimately running. The error_type='RecoverySweep' /
"no completion signal received within 5 min" message was misleading
— the worker was busy, not stuck.
Root cause is two interacting limits, both undersized for video work:
tag_and_embed: soft_time_limit=300, time_limit=420
(sized for the image branch, ≈2 GPU ops)
recovery sweep: STUCK_THRESHOLD_MINUTES = 5 across all queues
The video branch samples 10 frames via ffmpeg, then runs tagger +
embedder on EACH frame — ~20 GPU ops vs 2 for an image. A loaded
ml-worker can take 5-10 min on a long video, which trips both
limits well before the task naturally finishes.
**Two-part fix**
1. `tag_and_embed` time limits bumped to soft=900 (15 min) / time=1200
(20 min). Sized for the video path's worst case; image runs return
in seconds and don't care.
2. New `QUEUE_STUCK_THRESHOLD_MINUTES` override dict in maintenance.py.
Queues with legitimately-long-running tasks (currently just `ml` at
25 min — 5-min buffer past the new hard kill) get their own
threshold; queues not in the dict use the default 5 min. The sweep
now issues one UPDATE per distinct threshold value, with
`queue.notin_(override_queues)` on the default pass so each row is
touched at most once.
Tests:
- _make_task_run helper accepts `queue=` (defaults to "default") so
existing tests use the default-threshold path.
- New test `test_recover_stalled_task_runs_ml_queue_uses_longer_threshold`
pins both directions: a 10-min-old ml row survives (fresh by 25-min
override), a 30-min-old ml row gets flagged.
After deploy, operator's mp4 ML jobs run to completion without
spurious RecoverySweep failures.
Operator-flagged 2026-05-27: walk the whole project for the same shape
as the min-dim Delete-button silent failure (crypto.subtle TypeError
on plain HTTP). FC runs over plain HTTP per the homelab posture;
Secure-Context-gated browser APIs are undefined on the production
origin.
**Audit results across `frontend/src/`:**
crypto.subtle.digest — 2 sites:
- MinDimensionCard (fixed 2026-05-27)
- BulkEditorPanel (THIS FIX)
navigator.clipboard — 1 site, already guarded:
- utils/clipboard.js writeText with execCommand fallback
serviceWorker / mediaDevices / Push / Web USB|HID|Bluetooth|Serial /
cookieStore / queryLocalFonts / WebAuthn / geolocation
— NOT USED, nothing to fix
Extension scripts (background.js) use crypto.subtle but run from
moz-extension:// which IS a Secure Context — left as-is.
**BulkEditorPanel double bug**
The bulk-delete UI on the gallery selection had been broken since
FC-3k shipped, in two ways:
1. `crypto.subtle.digest` swallowed TypeError on plain HTTP — modal
never opened. Same symptom as min-dim.
2. Even on HTTPS, the modal's `kind="images-selection"` produced
`delete-images-selection-<sha8>` while the backend expected
`delete-images-<sha8>`. The two would never match.
Fix:
- Backend `/api/admin/images/bulk-delete` dry-run response now returns
`confirm_token` (the canonical `delete-images-<sha8>` string).
Integration test `test_bulk_delete_dry_run_returns_counts` pinned to
assert the new field.
- DestructiveConfirmModal gains an `expectedTokenOverride` prop. When
set, it bypasses the `${action}-${kind}-${runId}` formula and uses
the explicit string. This decouples the UI label (`kind`) from the
wire-format token (server-provided), so future endpoints can use a
kind-specific label without their kind name leaking into the token.
- BulkEditorPanel passes `:expected-token-override="bulkProjected?.confirm_token"`
— no client-side crypto, no kind-prefix mismatch.
- MinDimensionCard refactored to the same explicit pattern (was
slicing the 8-char suffix off the backend's token and passing it
through `runId`; now passes the full backend token via
`expected-token-override` directly). Cleaner; one source of truth.
**Banked memory**
`feedback_no_secure_context_apis.md` documents the full table of
Secure-Context-gated APIs, which ones FC currently uses, and how each
is handled. Indexed in MEMORY.md. Sites for the audit also listed in
the memory for future drift-checking.
No other Secure-Context-gated APIs found in `frontend/src/`. The same
shape won't recur unless someone adds a new dependency on one — at
which point the banked memory should fire.
**showcase R-key + entry animation**
Restores two behaviors lost during the FC-2 IR→Vue port. Operator-flagged
2026-05-27.
- ShowcaseView listens for keydown 'r'/'R' on window. Triggers
`store.shuffle()`. Skips when an input/textarea/contenteditable is
focused or a Vuetify overlay is open (the dialog/menu sets
`.v-overlay--active` on the body).
- MasonryGrid gains an opt-in `animateFromIndex` prop (default
`Number.POSITIVE_INFINITY` = off). When set, items with index ≥ the
threshold animate in with a stagger fade-in: 12px translateY,
0.25s ease, 60ms per item, capped by `prefers-reduced-motion`.
Stagger uses original-items-array index (resolved via an `idxById`
Map) so the reading order is preserved even after the masonry
distributes items across columns.
- ShowcaseView watches `store.images.length`: shrink-or-zero baseline
⇒ `animateFromIndex=0` (animate everything on initial load /
shuffle); grow ⇒ baseline=prevCount (animate only the appended
tail on infinite-scroll). Other MasonryGrid consumers (ArtistView's
Gallery tab) don't pass the prop, so they keep their current
no-animation behavior.
Direct port of IR's `app/static/js/showcase.js` keyboard handler +
`app/static/style.css` itemFadeIn keyframe.
**min-dim Delete: crypto.subtle TypeError fix**
The Delete button on the Cleanup → Minimum Dimensions card was
silently no-op'ing. Root cause: `crypto.subtle` is Secure-Context-gated
(undefined on plain-HTTP origins per the homelab posture). The card's
`onDeleteClick` computed the Tier-C confirm token via
`crypto.subtle.digest('SHA-256', ...)`, which threw TypeError before
`showModal.value = true`. The promise rejected, the click handler had
no `.catch`, the modal never opened — exactly the operator's reported
symptom.
Same shape as the v26.05.26.0 `navigator.clipboard` fix on the
ErrorDetailModal Copy button.
Fix: backend `/api/cleanup/min-dimension/preview` now returns
`confirm_token` (the canonical `delete-min-dim-<sha8>` string) in its
response. Frontend reads it from the preview response and feeds the
8-char suffix to DestructiveConfirmModal's `runId` prop — no
client-side crypto needed. Single source of truth.
Integration test `test_min_dimension_preview_returns_count` pinned to
also assert `body["confirm_token"]` matches the server-side compute.
Operator-flagged 2026-05-27: HF source check 401'd on
`HEAD /?enterAgree=1` even with valid login cookies. Root cause is the
combination of (1) gallery-dl's HF extractor checking
`self.cookies.get("PHPSESSID", domain="www.hentai-foundry.com")` with
`requests`' EXACT domain matching, and (2) the extension's cookies.js
forcibly rewriting every captured cookie to a leading-dot subdomain-wide
form. HF's PHPSESSID is browser-stored as host-only on
`www.hentai-foundry.com`; the rewrite re-anchored it to
`.hentai-foundry.com`, which `cookies.get(...)` no longer matches even
though the cookie is still sent on actual HTTP requests (RFC 6265
subdomain rules). The extractor falls into its unauthenticated
`?enterAgree=1` fallback, which 401s (Cloudflare or HF's anti-bot HEAD
gating).
Two-part fix, no operator action required for existing stored cookies:
1. **Backend** (`credential_service._augment_cookies`) — refactored from
the subscribestar-only single function into a per-platform dispatcher.
New `_augment_hentaifoundry` parses the materialized netscape file
and, for each `.hentai-foundry.com` entry whose name is PHPSESSID or
YII_CSRF_TOKEN, appends a host-only duplicate
(`www.hentai-foundry.com\tFALSE\t...`). Originals preserved. Three
new tests pin: injection fires + originals preserved; idempotent
when host-only already exists; doesn't touch unrelated cookies
(e.g. `_ga`).
2. **Extension** (`cookies.js`) — `toNetscapeFormat` now respects
`c.hostOnly` from the browser instead of blindly forcing a
leading-dot subdomain-wide form. Host-only cookies are written with
the bare host + FALSE flag; non-host-only cookies retain the
leading-dot + TRUE form. Forward-compat — fresh captures from
v1.0.5+ no longer need the backend's host-only duplication.
Extension bumped 1.0.4 → 1.0.5; manifest + package.json in lockstep.
After deploy: the next HF source check on the operator's already-stored
cookies will succeed because the materialized cookies.txt now contains
host-only PHPSESSID. No browser re-export needed.
Operator-flagged 2026-05-27: subscribestar source check aborted with
`AbortExtraction: HTTP redirect to .../age_confirmation_warning`. The
captured `_personalization_id` cookie in the browser-stored file had
expired (annual rotation), and the user could not realistically refresh
it: SubscribeStar's frontend JS uses localStorage to suppress the
age-confirmation popup once dismissed, so a logged-in revisit doesn't
re-show the popup and the server-side cookie is never re-issued.
gallery-dl's own login flow (which FC doesn't exercise — cookies come
from the extension instead) sidesteps this by manually setting
`18_plus_agreement_generic=true` on `.subscribestar.adult`. The server
accepts that as the age-confirmation marker.
`credential_service._augment_cookies(platform, netscape)` mirrors that
behavior: when the materialized cookies file is for subscribestar and
the age cookie isn't already present, append a synthetic line for
`.subscribestar.adult` with name=`18_plus_agreement_generic` value=`true`
and a far-future expiry. No-op for other platforms; no-op if the cookie
is already present (idempotent for manual pastes / extension captures
that happen to include it).
Three new tests pin: (a) injection fires for subscribestar, preserves
existing cookies; (b) idempotent when already present (no double
injection); (c) does NOT fire for non-subscribestar platforms (Patreon
etc. don't get a foreign-domain cookie).
Not a curator handling bug per se — the extension faithfully captured
what the browser had. This is mirroring a documented gallery-dl
workaround so the cookies-via-extension auth path doesn't degrade as the
server-side cookie expires.
Audit of one sample sidecar per platform on the operator's
/mnt/Data/Patreon/ archive surfaced three parser bugs that have been
silently corrupting non-Patreon Posts since FC-3 shipped:
1. SubscribeStar `id` vs `post_id` confusion. gallery-dl puts the
per-attachment id in `id` (e.g. 711509) and the actual post id in
`post_id` (e.g. 360360). FC's external_post_id chain had `id`
winning, so every multi-image SubscribeStar post was fragmented into
N Post rows in the database. Reorder the chain to
`("post_id", "id", "index", "message_id")` — Patreon/Pixiv (no
`post_id`), HF (uses `index`), Discord (uses `message_id`) all
unaffected.
2. Discord `message` field not captured. Discord posts put the body in
`message`, not `content`. Append it to the description fallback chain
`("content", "description", "caption", "message")`.
3. post_url is the file URL on SubscribeStar/Pixiv/HF/Discord. New
`_derive_post_url(platform, data)` helper synthesizes proper
permalinks from per-platform fields:
subscribestar → https://www.subscribestar.com/posts/<post_id>
pixiv → https://www.pixiv.net/artworks/<id>
hentaifoundry → https://www.hentai-foundry.com/pictures/user/<user>/<index>
discord → https://discord.com/channels/<server>/<channel>/<message>
Patreon's bare `url` IS a real permalink and is used as-is. For the
four file-URL platforms, the bare `url` is NEVER trusted: derive or
return None rather than persist a CDN URL.
Tests:
- `test_parse_core_fields_and_id_priority` flipped to assert post_id
wins over id.
- New `test_parse_id_used_when_no_post_id` covers the Patreon real
shape.
- New `test_parse_message_used_as_description_fallback` covers Discord
bodies.
- Five new tests cover per-platform post_url derivation
(SubscribeStar/Pixiv/HF/Discord/Patreon-untouched + missing-fields →
None).
Cleanup migration alembic 0025_fix_subscribestar_post_ids:
- For each SubscribeStar Post: find a related ImageRecord.path, walk to
its sidecar JSON, read `post_id`, overwrite Post.external_post_id +
post_url with the corrected values.
- After all updates, every group of Posts under one source sharing the
same NEW external_post_id is a fragment-set — merge to a canonical
row using the same ImageProvenance pre-delete + repoint dance as
alembic 0022 (banked pattern).
- Pure-SQL backfill of Pixiv post_url: replace any `i.pximg.net`-shape
url with the derived `/artworks/<id>` permalink.
- HF and Discord post_url backfills skipped — HF would need the `user`
field (not stored on Post), Discord needs server/channel triple.
Both will be corrected by a deep-scan re-applying sidecars through
the new parser.
Idempotent: re-running on already-corrected data is a no-op.
SubscribeStar gallery-dl always writes `title: ""` and embeds the leading
sentence inside `content` HTML. Confirmed against the operator's
/mnt/Data/Patreon/Cheunart/subscribestar/ dump 2026-05-27: every
post's JSON has `title: ""` and a content like
`<div>Lets say hello to you guys with my Belle <br><br><br></div>`.
FC's sidecar parser, treating empty strings as missing, had been leaving
post_title NULL on every subscribestar post since FC-3 shipped.
Fix at two layers:
1. `backend/app/utils/sidecar.py` — new `_first_line_text(body, limit)`
helper strips HTML tags, collapses whitespace, returns the first
non-empty line truncated to 120 chars with ellipsis. `parse_sidecar`
now falls back to this when `title` resolves to None and a
`content`/`description`/`caption` value is present. Patreon's
non-empty titles short-circuit the fallback so existing behavior is
unchanged. Four new tests in test_sidecar_util.py pin: derivation
from content, truncation at 120 chars, explicit-title precedence,
no-content no-fallback.
2. `alembic 0024_backfill_post_title_from_description` — backfills the
same logic across existing Post rows where `post_title IS NULL OR
post_title = ''` AND description is present. Idempotent (re-running
is a no-op once titles are populated). Downgrade is a no-op since
there's no safe way to tell derived rows from genuine ones.
After deploy + migration: subscribestar posts will surface a meaningful
title in PostCard, post feed search, etc.
Replaces the three top-level routes with a single `/subscriptions` parent
owning the whole download-pipeline domain. Internal tab state via `?tab=`
query param, mirroring ArtistView's pattern. TopNav auto-drops the two
removed entries (route-driven via meta.title). Bookmark-safe redirects
from `/credentials` and `/downloads` route into the appropriate subtab.
**Subtab 1 — Subscriptions (default).** Carries over the existing
artist-grouped expandable table; adds (a) status filter dropdown, (b)
bulk-select column with Enable/Disable/Delete-all actions, (c) GS-style
color-coded `PlatformChip` per distinct platform in the collapsed row.
Reuses SourceRow, SourceHealthDot, SourceFormDialog, ArtistCreateDialog.
**Subtab 2 — Downloads.** Full GS dashboard. Five colored stat chips up
top (Queued/Running/Completed/Failed/Skipped, sourced from new
`GET /api/downloads/stats?window_hours=`). Popover-style filter UI
(Status/Source/FromDate/ToDate) with active-filter pills below.
Maintenance menu wraps existing /api/import/retry-failed and
/api/import/clear-stuck endpoints; Export-failed-logs item disabled with
a "v2" tooltip. Per-row Retry preserved via existing DownloadEventRow.
**Subtab 3 — Settings.** Four sections: ExtensionKeyBar (top), GS-style
per-platform CredentialCard grid (md=6 v-row/v-col, dashed border if
unset / accent border if set, expandable how-to panel), Downloader card
(rate limit, validate_files), Schedule defaults card (default interval,
event retention, failure warning threshold). The Downloader and Schedule
sections were extracted out of components/settings/ImportFiltersForm.vue
— SettingsView's Import tab now owns only image-import filters.
**Backend:** new `GET /api/downloads/stats` returns
{pending, running, ok, error, skipped} count grouped by status over the
configurable window. Status keys stay raw from the ENUM; UI does the
display-label mapping. Two integration tests pin the response shape +
window_hours validation.
**Util:** `frontend/src/utils/platformColor.js` — single source of truth
for the six platforms' color + icon + label, mirroring GS's palette
(patreon=red mdi-patreon, subscribestar=amber mdi-star,
hentaifoundry=purple mdi-palette, discord=indigo mdi-discord,
pixiv=blue mdi-alpha-p-box, deviantart=green mdi-deviantart). Unknown
platform falls back to grey + mdi-web.
Deferred (explicit non-goals): subscription import/export, "Trigger Due
Now" scheduler-tick button (needs new backend endpoint), Export Failed
Logs CSV dump.
The two prefix-parsing tests were pinned to `artist:Eric`, but `artist`
was removed from KNOWN_KINDS in commit 4cad07a (provenance is a separate
axis from tags). The parser now keeps `artist:` literal, so the assertion
`body["name"] == "Eric"` failed.
Repointed to `character:Saber` (still in KNOWN_KINDS). Also updated the
stale `artist:` docstring example in parse_kind_prefix to `fandom:`.
Caught by [[reference-grep-pinned-tests-in-plans]] — should have grep'd
tests/ for `artist:` when shrinking KNOWN_KINDS. Banking the miss.

_apply_sidecar is additive: it find-or-creates Post/Source/ImageProvenance
and sets primary_post_id NULL-only, so any IR-migration provenance on the
existing row survives untouched and the new GS sidecar adds a second
ImageProvenance pointing at the freshly-created Post.
Wrapped in try/except so a malformed sidecar can't unwind the file-swap
commit — the file replacement is the critical operation.

Operator hit 3 large PNGs stuck in 'processing' for 2 days 2026-05-25:
the existing recover_interrupted_tasks flips processing > 5min back to
queued + .delay(), but if the underlying file is unfixably broken (e.g.,
PIL OSError, also patched in 68cffce), the loop never terminates and the
'Scanning...' banner sticks at 0/0 forever blocking new scans.
/api/import/clear-stuck:
- Flips every task in pending/queued/processing to 'failed' with a clear
marker error message
- Finalizes any 'running' ImportBatch that has no remaining active children
- Idempotent + non-destructive: rows survive, can be retried once the
underlying cause is resolved
UI button 'Clear stuck...' sits next to 'Retry failed' / 'Clear completed'
with a warning-tonal alert in the confirm dialog explaining what it does
and recommending Retry failed once the cause is fixed.
Tests: clears mixed non-terminal states, untouches complete rows,
finalizes orphan batch, no-op when nothing stuck.

Operator hit this 2026-05-25 after the IR tag_apply landed: ~57k images
all scanned into FC in the same week share image_record.created_at, so
the gallery timeline collapses them into a single month bucket and
scroll orders them all together at the top. Their actual publish dates
(spread over years) were already available in Post.post_date but the
gallery never read it.
Backend wire-up:
- tag_apply phase 4 now sets ImageRecord.primary_post_id when creating
ImageProvenance (only if currently NULL — preserves the canonical
download-time linkage set by the importer for new FC ingests).
- gallery_service.py introduces _effective_date_col() =
COALESCE(post.post_date, image_record.created_at), used in:
* scroll() ORDER BY + cursor WHERE clauses

- Each method LEFT OUTER JOIN Post on primary_post_id so the COALESCE
works for images without a post (NULL on the Post side, fall back
to created_at).
- GalleryImage gains posted_at + effective_date fields; API /gallery
/scroll exposes both alongside the existing created_at so the UI
can render 'Posted on X (imported Y)' if desired.
- get_image_with_tags() returns posted_at for the modal.
Cursor format unchanged — the encoded datetime is now the effective_
date (whichever column won the COALESCE) and pagination remains
consistent.
To pick up new behavior for an already-migrated IR set: re-run
/api/migrate/tag_apply on the existing manifest (phase 4 is
idempotent; the new primary_post_id assignment backfills).

_PLATFORM_PROFILE_URL had only patreon/subscribestar/hentaifoundry but
FC's extension_service.py recognizes 5 platforms. Any IR PostMetadata
with platform=deviantart or pixiv fell through _profile_url returning
None and the entry was silently skipped — explaining operator's
2026-05-25 finding that IR-migrated images had tags but no provenance
for the deviantart + pixiv subscriptions.
Pixiv caveat noted in comment: real profile URL takes numeric user_id
(https://www.pixiv.net/users/12345) but IR's PostMetadata.artist
stores display name. We slug the name and use it as if it were the id
so the artist->post->image linkage survives migration; the resulting
Source.url won't resolve in a browser and operator can fix via
Settings -> Subscriptions later if they want.
To recover existing IR-migrated state: re-run /api/migrate/tag_apply
on the existing manifest. Phase 4 is idempotent; new posts get
inserted only for the previously-skipped platforms.

Operator hit a corrupt JPEG in the IR set 2026-05-25: PIL.verify() only
validates header structure but doesn't catch truncated/broken pixel
data. The error surfaces later in _transparency_pct (via getchannel
'A' -> load) or compute_phash (load) — both blow up with OSError
'broken data stream when reading image file'. Celery's autoretry_for
then bounces the same file forever instead of marking it skipped.
Wrap both PIL.load-triggering call sites with try/except OSError ->
ImportResult(status=skipped, skip_reason=invalid_image).

The HF repo Camais03/camie-tagger-v2 has camie-tagger-v2.onnx (789 MB)
+ camie-tagger-v2-metadata.json (7.77 MB) at root, NOT model.onnx +
selected_tags.csv. Tags ship as nested JSON (dataset_info.tag_mapping)
not CSV. Per the published onnx_inference.py reference: input is NCHW
not NHWC, normalize with ImageNet mean/std, pad-square color (124,116,
104), sigmoid the second output (refined predictions) not the first.
Operator hit this during the IR migration ML backfill — download_models
silently fetched only 3 json files (allow_patterns matched nothing
useful), tagger.load() then raised RuntimeError. Fetched the actual
v2 layout via WebFetch, rewrote tagger to match published reference.

scan_directory creates ImportTask rows with status='pending' (commit) then
in a second pass transitions to 'queued' + .delay() (commit). Crashes in
that window leave rows orphaned with no recovery path. Operator hit 5490
such rows 2026-05-25; the existing sweep only handled 'processing'.
Flipping to 'failed' (not re-enqueue) lets the operator drain via the
existing /api/import/retry-failed endpoint at their own pace.
