The headline bug: aliases created from the modal NEVER resolved. Create
sent the normalized display name ('Sword', 'Uchiha Sasuke') while
resolution keys on the raw booru model key ('sword', 'uchiha_sasuke',
case-sensitive) — so the mapping was stored under a key nothing looks up,
and the prediction kept reappearing unaliased. The raw key wasn't even in
the /suggestions response, so the modal couldn't send it.
- Suggestion now carries raw_name (the model key an alias must use) and
via_alias (surfaced via an operator alias); both serialized by the API.
- Modal alias-create sends raw_name, not display_name (the fix). Aliased
suggestions show an 'alias' badge and a 'Remove alias' action; 'Treat as
alias for…' is hidden for centroid hits (no model key) and already-aliased
rows.
- Tag-side management: TagCard ⋮ → 'Aliases…' opens a dialog listing the
model keys that fold into a tag, with remove (GET /api/tags/<id>/aliases +
AliasService.list_for_tag). Creation stays in the modal suggestion flow.
Tests: full API round-trip locking the raw-key contract (raw_name exposed →
alias authored with it → resolves + via_alias on a later image);
list_for_tag (service + API); via_alias/raw_name on the existing service
suggestion tests. No migration.

An image whose on-disk path contains '#' (post folders like 'BLUE#59')
served its hash-named thumbnail fine but 404'd the original: the unencoded
'#' in image_url was parsed by the browser as a URL fragment, so
'#59/01_timelapse.jpg' never reached the /images route. Add a shared
image_url(path) helper that percent-encodes the path (safe='/') and route
the 3 raw builders (gallery detail + 2 in series) through it. Not a
cleanup-tool deletion — the file is on disk; only the URL was wrong.

The Browse tab nav scrolled away (operator didn't know it existed) and
Posts had no search. Roll the tab strip + a shared search field into one
sticky block pinned under the 64px TopNav.
- Posts gains server-side text search: PostFeedService.scroll()/around()
+ /api/posts accept q (ILIKE over post_title OR description), applied
INSIDE the artist/platform WHERE so search stays scoped to the active
filter. Scope shown as clearable chips next to the search field.
- Artists/Tags search consolidates into the sticky bar: their inner
search boxes are removed; they react to route.query.q (q is deep-
linkable, e.g. /browse?tab=posts&q=foo). Platform/kind filters stay.
- Posts empty state now distinguishes 'no matches' from 'no posts yet'.
Tests: posts q-search matches title|description and stays artist-scoped
(service); q passthrough (api).

add_post now stamps the post's parsed START (constant) on every staged
pending page so the group start survives junk removal; list_pages
surfaces it as start_page. Update the stale per-page [9,10,11] assertion

Replaces the auto-renumbered 1..N position key with operator-OWNED page
numbers: sparse, gaps allowed, editable, never auto-renumbered. Order follows
the numbers; unnumbered pages sort to the tail. This is the fix for the model
that clobbered hand-set numbers on the flatten — numbers are now data, not a
derived sequence.
- series_service: drop the renumber-on-reorder/remove; order by page_number
NULLS LAST; new set_page_number(image_id, n|None); list_pages returns `gaps`
(one entry per missing-number run) + each pending group's parsed `start_page`;
set_cover renumbers below the current min; place_pending(image_ids, start_page)
numbers placed pages sequentially from the start (drop junk first → numbers
line up); add_post stamps the parsed start on staged pages.
- api/tags: POST /series/<id>/pages/number (set one page's number); /pending/
place takes start_page; removed /reorder.
- frontend: per-card editable number input; one gap block per gap with
drop-on-edge to assign the adjacent number (middle → type); append drop zone;
pending tray gets a "from page N" field + "Place from page N".
- tests reworked: sparse numbers + gaps, place-from-start, set-page-number route.
No migration; nothing destructive.

Add-from-post no longer appends straight into the run — it STAGES the post's
pages as pending (per-page status; page_number NULL), grouped by source post,
so the operator drops junk (text-free alts, bumpers) and places the keepers
into the sequence with clean series-global numbering.
- migration 0048: series_page.status ('placed' default | 'pending') + nullable
page_number.
- series_service: placed/pending split everywhere (list_pages returns the
placed run + a `pending` section grouped by source post; reorder/cover/
list_series operate on placed only); add_post stages pending; new
place_pending(image_ids, before_image_id=None) flips pending→placed spliced
before a page (or appended) and renumbers; junk removal reuses remove_images.
- api/tags: /add-post now returns staged count; new POST /series/<id>/pending/
place.
- frontend: PostSeriesMenu navigates to the series after staging; seriesManage
store surfaces `pending` + placePending; SeriesManageView gains a pending
tray (per-post groups, place-all / place-one / drop-junk).
- tests: pending staging, place (append + insert-before), ignore-already-
placed, drop-junk, route guard; updated add_post + match-accept expectations.

Reframe a series from "ordered chapters that own pages" to ONE flat,
series-global ordered run of pages with optional cosmetic chapter DIVIDERS
over it. A chapter no longer wraps content — it's a labeled divider anchored
to the page that begins it; a page's chapter is derived as the nearest
preceding divider. This is what lets installments assembled from multiple
sources sit in one continuous, correctly-numbered sequence (operator's
Goblin Juice case).
- migration 0047: flatten each series to a series-global page_number
(preserving today's reading order); convert each existing chapter to a
divider anchored at its first page (keeping title/stated_part); drop
series_page.chapter_id; reshape series_chapter (anchor_page_id UNIQUE FK,
drop chapter_number/is_placeholder/stated_page_start/end). Loss-safe for
content; drops empty placeholder chapters + a redundant page-1 divider.
- series_page: page_number is now the series-global order; no chapter_id.
- series_chapter: anchored divider (anchor_page_id, title, stated_part).
- series_service: flat list_pages (one run + derived dividers + per-page
source_post + part_gaps), series-wide reorder/renumber, divider CRUD
(create/update/move/delete); retired per-chapter reorder/merge/placement.
- api/tags: drop chapter_id from add; /chapters endpoints are divider
create/update/delete (removed chapter reorder/merge/page-reorder).
- series_match_service: series "end" reads max(series_page.stated_page);
accept appends via add_post. tag_service series-merge appends src's pages
after tgt's max so the merged series stays one clean run.
- frontend: seriesManage store + SeriesManageView → one continuous
drag-reorder grid with inline divider bars + series-global page numbers;
reader walks the flat run, headings from dividers; PostSeriesMenu copy.
- tests reworked across the series suite for the divider model.
Phase 2 (pending staging for add-from-post) is separate.

Read cutover verified in prod (suggestions + allowlist read image_prediction;
backfill complete at 908k rows / 51k images). Removes the old JSON column and
everything that fed it:
- ImageRecord.tagger_predictions column removed; migration 0046 DROPs it.
tagger_model_version kept as the "tagged / current?" signal the backfill
sweep reads (needs-tagging check switched to tagger_model_version IS NULL).
- tag_and_embed no longer dual-writes the JSON — image_prediction is the only
write path.
- importer re-import reset drops the JSON line (image_prediction rows are
already deleted on re-import).
- Retired the one-time #768 backfill task + the #764 prune task, their admin
endpoints, and their Maintenance cards (Backfill/PrunePredictionsCard).
- Tests seed/assert via image_prediction; stale column refs removed.
Disk reclaim is NOT automatic: DROP COLUMN is a catalog change. Run
`VACUUM FULL image_record` off-hours afterward to return the ~100 GB to the OS
so DB backups go small (#739). image_prediction (~90 MB) stays in pg_dump — it's
the source of truth now.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
The inline INSERT…SELECT backfill in migration 0045 wrapped the table
creation and a ~100 GB pass over image_record.tagger_predictions in one
transaction: nothing committed until the end, it was unmonitorable, and an
earlier MATERIALIZED-CTE form spilled the full 100 GB to temp on NFS. A
deploy got stuck on it for ~2h with image_prediction never appearing.
Split the concerns:
- 0045 now creates ONLY the table + indexes (instant DDL → web boots).
- New backend.app.tasks.admin.backfill_image_predictions_task copies the
>= store-floor predictions from the JSON into image_prediction, batched by
id window and committed per chunk: live progress, resumable (re-enqueues
from the last committed id), idempotent (ON CONFLICT DO NOTHING). json_each
stays in the DB executor streaming each window — no Python-side 100 GB load,
no materialization.
- POST /api/admin/maintenance/backfill-predictions + a Maintenance-tab card
to trigger the one-time run after upgrading.

Switch every prediction READER off the JSON column onto the normalized
image_prediction table. Parity by construction: each reader loads the same
{raw_name: {category, confidence}} dict it consumed before (via small
_load_predictions helpers), so all downstream threshold/alias/merge/consensus
logic is byte-identical — only the data source changed.
- suggestions.SuggestionService.for_image (and for_selection via it)
- ml.apply_allowlist_tags (iterates images that have prediction rows)
- importer re-import reset deletes the image's prediction rows
The tagger_predictions JSON column is still dual-written (step 1) so it stays
valid during transition; the backfill task's NULL check still works. Removing
the JSON write + DROP column + retiring the #764 prune is the cleanup
follow-up (needs a quiesced-worker window for the DROP lock).
Tests: shared tests/_prediction_helpers.seed_predictions seeds the table;
read-path tests (suggestions, bulk consensus, allowlist apply, API) seed there
instead of ImageRecord.tagger_predictions.

Normalize tagger predictions out of the image_record.tagger_predictions JSON
blob into a queryable per-prediction table. Step 1 of the cutover (expand):
additive + low-risk — reads still use the JSON, this just adds the table and
keeps it populated.
- ImagePrediction(image_record_id, raw_name, category, score) — stores the
RAW tagger vocab name (not tag_id) so read-time alias→canonical resolution
is unchanged. Indexed for per-image reads + by (raw_name, score).
- Migration 0045: create table + set-based backfill from the JSON via
json_each (fast post-#764-prune). The old column stays (vestigial) and is
dropped in a later follow-up — DROP needs an ACCESS EXCLUSIVE lock on the
hot image_record table, so it waits for a quiesced-worker window.
- tag_and_embed dual-writes the rows (delete-then-insert, idempotent);
tagger_store_floor already applied in infer().
Next: switch suggestion + allowlist reads to the table, then drop the JSON
write. Plan-task #768.

DB backup polish (plan-task #764 Q3):
- pg_dump now uses custom format (-Fc): compressed (much smaller on NFS) and
restored via pg_restore. Artifact extension .sql → .dump; restore_db swaps
psql -f for pg_restore -d. BackupRun.sql_path field name kept (it's just the
db artifact path).
- Reconcile the subprocess guardrails: the DB timeout was 720s with a stale
'Celery soft is 10 min' comment, but backup_db_task's soft limit is actually
1800s — so the bounded-kill fired 18 min early. Set DB=1700s / images=21000s,
each just under its task's Celery soft limit so _run_bounded stays the
primary guard (an NFS D-state hang defeats Celery's own SIGKILL).
Real shrink of the DB is the #764 prune; this makes each dump smaller/faster
on top of that.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
The one-time backfill that actually shrinks the DB: drops stored
tagger_predictions entries below ml_settings.tagger_store_floor from every
image_record row, and clamps any allowlist min_confidence below the floor up
to it. Keep predicate (confidence >= floor) mirrors Tagger.infer's store gate
so backfilled rows match new imports. Keyset by id ASC, idempotent,
self-resumes on the soft time limit; runs on the maintenance_long lane.
pg_dump copies live data only, so this alone fixes the #739 backup timeout —
the reclaim (VACUUM FULL / pg_repack on image_record) is a separate, optional
disk-return step, brief because post-prune the live data is tiny.
- admin.prune_low_confidence_predictions_task + POST /api/admin/maintenance/prune-predictions
- PrunePredictionsCard in the Maintenance panel (shows the current floor)
- tests: registration + prune-keeps->=floor/drops-<floor + allowlist clamp

Consumer #4 of the store-floor change (#764). An allowlist tag can't
auto-apply more permissively than the ingest floor — predictions below
tagger_store_floor aren't stored, so a lower min_confidence behaves
identically to the floor. update_threshold now clamps to max(value, floor);
the AllowlistTable confidence input min-binds to the live floor and clamps
on edit. Keeps the stored threshold honest about actual apply behavior.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Promotes the prediction store-floor from the TAGGER_STORE_FLOOR env (default
0.05) to a DB-backed, Settings-UI-tunable ml_settings column (default 0.70).
Storing every tag down to 0.05 from a ~10k-tag tagger is what grew
image_record's TOAST to ~100 GB; the suggestion path already filters at 0.70
and the centroid/learned path covers lower-confidence preferred tags, so the
sub-0.70 tail is redundant. Foundation for plan-task #764 (backfill + reclaim
land next; this only changes the write gate for NEW imports).
- ml_settings.tagger_store_floor (migration 0044, default 0.70)
- tagger.Tagger.infer(store_floor=...); ml task passes settings.tagger_store_floor
- ML admin GET/PATCH expose it; PATCH rejects a category suggestion threshold
below the floor (nothing below the floor is stored, so the gap surfaces
nothing) — server backstop for the UI slider clamp
- Settings → ML: store-floor slider + caption; category sliders min-bound to it

recover_stalled_task_runs used the 5-min default for the download queue,
but download_source legitimately walks up to DOWNLOAD_HARD_TIME_LIMIT
(1500s = 25m). Healthy in-flight Patreon/gallery-dl walks were flagged as
phantom 'RecoverySweep' failures — visible in System Activity but absent
from the Subscriptions view (the download finished ok, reset the source's
consecutive_failures; only the orphaned task_run kept the stamp, since
_finalize only updates rows still 'running').
Add download:30 to QUEUE_STUCK_THRESHOLD_MINUTES — clears the 25-min hard
limit with buffer and matches DOWNLOAD_STALL_THRESHOLD_MINUTES so a real
hard kill is swept by the task-run and event sweeps together. Restores the
documented invariant (every override >= task time_limit). Regression test
pins the threshold above the hard limit so a future limit bump can't
silently re-break it.

Recent failures gains a client-side search over the already-loaded 24h
rows (task/queue/target/error), shown as a filtered/total count alongside
the existing error-type chips. All recent activity gains a debounced

spans the full history, not just the loaded page. LIKE wildcards are

The fandom self-join (resolve a character's fandom NAME via Tag.fandom_id->Tag)
and the {id,name,kind,fandom_id,fandom_name} dict were hand-written in
TagService.autocomplete/.list_for_image, GalleryService.get_image_with_tags and
the api/tags handlers — the last few grown by this session's fandom-on-chip
feature. Consolidate to services/tag_query: fandom_join_alias() + tag_columns()
build the select; serialize_tag(row) builds the dict. Now a new tag field is
added in one place.
Over-DRY guard: TagDirectoryService selects the full Tag ORM + an image-count
aggregate (a different select shape) — left as its own variant. §8b: the
fandom_lookup alias lives only in tag_query; gallery + both api/tags handlers
serialize via serialize_tag. Test: serialize_tag handles enum + string kind.

The find-or-create dance — SELECT, then a SAVEPOINT INSERT that recovers (not a
full rollback) on IntegrityError when a concurrent worker inserted first — was
hand-rolled identically in 4 async sites: ArtistService.find_or_create,
TagService.find_or_create, ExtensionService._find_or_create_artist and
._find_or_create_source. Divergent copies of exactly this pattern are how the
duplicate-row/race bugs in reference_scalar_one_or_none_duplicates crept in, so
it now lives once in services/db_helpers.get_or_create (returns (row, created);
factory adds+flushes+returns the row; caller owns the outer commit).
Over-DRY guard: SourceService's IntegrityError sites RAISE DuplicateSourceError
(reject-on-conflict, a different concept) — left alone. Importer._get_or_create
is the lone SYNC consumer (already shared by 2 callers) — stays separate, can't
cross the sync/async boundary. §8b: no hand-rolled async find-or-create remains.
Test: get_or_create creates then returns existing without re-invoking the factory.

The typed dropdown sourced the threshold-filtered panel list (>= 0.70 general),
so low-confidence actions/features the model DID predict never appeared — forcing
hand-typed custom tags instead of accepting the model's canonical formatting.
Add a threshold override: SuggestionService.for_image(threshold_override=) and
GET /images/<id>/suggestions?min=<f> surface EVERY stored prediction (down to the
0.05 store floor), alias-resolved and normalized, still excluding applied/rejected
and unsurfaced categories. The suggestions store gains allByCategory + loadAll
(min=0); the dropdown searches that full set (cap 20), while the Suggestions panel
stays curated at the configured threshold. Accept/dismiss drop from both lists.
Operator-asked 2026-06-09. Test: a 0.30 general prediction is hidden by default
but surfaced with threshold_override=0.0; unsurfaced categories still excluded.

The native Patreon backfill flooded the feed with bare 'Post <id>' shells
(1589 for Anduo). Root cause: PostAttachment.sha256 was GLOBALLY unique, so a
non-art file reused across posts only ever linked to the first one, and
_capture_attachment created the Post before that dedup check — leaving later
posts with no image and no attachment. Duplicate IMAGES had the mirror gap:
attach_in_place returned duplicate_hash/duplicate_phash before _apply_sidecar,
so the second post got no provenance row, and the feed only rendered via
primary_post_id (one post per image).
Operator requirement: a duplicate item must show on EVERY post it appears in.
Unify the fix as link-not-suppress:
- importer: on duplicate_hash / duplicate_phash(larger_exists), append an
image_provenance row for the new post (keep primary on the first). Both the
download path (attach_in_place) and the filesystem path (_import_media).
- post_feed_service: render thumbnails by image_provenance UNION primary_post_id,
so a cross-posted image shows on every post (and legacy primary-only images
still show).
- PostAttachment: per-post uniqueness — drop UNIQUE(sha256), add partial
UNIQUE(post_id, sha256) + partial UNIQUE(sha256) WHERE post_id IS NULL
(migration 0043); _capture_attachment dedups per-(post,sha) over the shared
sha-addressed blob, so no post is left bare.
- cleanup: new prune-bare-posts maintenance action (cleanup_service
_bare_post_conditions shared by preview/count/delete per preview/apply parity;
admin endpoint; PostMaintenanceCard). Deletes posts with zero image links
(primary or provenance) AND zero attachments. Run after the feed fix so a
hidden provenance link spares the post instead of deleting it.
Tests: dup image shows on both posts; dup attachment shows on both posts; feed
renders provenance-linked duplicates; prune-bare delete-path == preview.
Operator redeploys (migration 0043) then runs the prune to clear the shells.

The character pointing at the fandom had no image associations, so it was
itself unused and inflated the dry-run count to 2. Tag it on a real image so
it is used (the real-world shape) — the fandom survives via a live character.

The fandom/chapter exclusions added in fb05c5e only touched find_unused_tags
(the preview SAMPLE). prune_unused_tags re-implemented the predicate inline for
the dry-run COUNT and the live DELETE with only the image_tag + series_page
checks — so the preview showed a safe list of names while the delete removed
every fandom (and chaptered series). Operator-flagged 2026-06-08: real data loss
— assigned fandoms deleted, their characters SET-NULLed.
Extract _unused_tag_conditions() as the single source of truth and use it for
the preview, the count, AND the delete, so they can never diverge again. Added a
prune-commit test asserting the LIVE delete spares a character's fandom and a
chaptered series.

find_unused_tags only excluded tags with image_tag or series_page references, so
it flagged every fandom as 'unused' — fandoms are NEVER applied to images (a
character carries its fandom via tag.fandom_id), and the FK is ondelete=SET NULL,
so deleting one silently strips the fandom off all its characters
(operator-flagged 2026-06-08: artist-OC fandoms showing as unused).
Exclude tags referenced as a character's fandom_id, and (same class of gap) tags
referenced by a series_chapter (an all-placeholder series has chapters but no
pages yet). A genuinely orphaned fandom with no characters is still swept.

_create_protective_aliases scanned every image_record's tagger_predictions JSON
(unindexed full scan, ~59k rows) to find the categories a merged-away tag's name
was predicted under. That scan ran inside the merge transaction AFTER it had
locked series_page — on a large library it held that lock for minutes and is what
blocked migration 0040 (and starved the standardization task into its 40-min
timeout).
The scan was redundant: the tagger's tag_to_category map is one-to-one (a name has
exactly one category) and a tag's kind is set from that category when created, so
kind already IS the tagger's category for the name. The scan only ever rediscovered
the kind. Build the single protective alias from src_kind directly — no scan, no
lock-holding slow step in the merge.
Rewrote test_alias_per_observed_prediction_category (which encoded the
can't-actually-happen one-name-two-categories case) → test_protective_alias_uses_tag_kind.

Operator feedback: thumbnails too small to judge order, no obvious way to mark
'this installment is Part 2', and the permanent two-pane picker was busy and
competed with the ordering work.
- Full-width parts, each a card with a big page grid (150px, contain so whole
pages are visible) and drag-to-reorder; positional page number as a badge.
- Editable Part # (hero field) backed by new series_chapter.stated_part —
separate from the auto-managed chapter_number, mirroring the page_number vs
stated_page split so reorder/delete renumbering can't wipe a hand-set part.
Missing-Part hints when consecutive parts' stated_part jump >1.
- Each part labels its source post (derived from pages' primary_post_id) and
shows the printed-page range with clear labels.
- Picker demoted to an on-demand right slide-over ('Add pages') with a target-
part selector; part actions (move/merge/delete) collapsed into an overflow ⋮.
alembic 0042 adds series_chapter.stated_part (nullable int).

#739 — DB backups hung on NFS in uninterruptible D-state, defeating the 12-min
subprocess timeout AND Celery's hard limit, so a stuck pg_dump held the
concurrency-1 maintenance_long lane for hours — starving normalize_tags,
re-extract, audits, and the new series rescan (which is why #740 "never
applied"). Three fixes:
- _run_bounded: Popen + bounded post-kill reap; if the child is unkillable
(D-state) we stop waiting and re-raise TimeoutExpired, freeing the slot. The
orphan is reaped by the OS once its syscall clears.
- backup_db dumps to a LOCAL temp file then moves the finished .sql to the
(NFS) _backups dir — pg_dump's long phase is now a DB-socket wait + local
writes (killable) instead of an NFS write that hangs. backup_images keeps
bounded-kill (too big to stage locally).
- recover_stalled_backup_runs: split the stall window — db 40 min (was sharing
images' 7h), so a hung DB backup is flipped to error promptly.
#740 — Standardize tag casing showed "0 groups to change" the instant it was
clicked: onNormCommit overwrote the preview with zeros. Keep the real preview
visible and disable the button while queued; backend apply was already correct.
Tests: fake subprocess.Popen alongside run; bounded-kill fail-fast; local-temp
target; per-kind stall sweep.

Confirm-only "this post may continue this series" matcher.
- series_suggestion table (post_id, series_tag_id, score, signals jsonb, status
pending|added|dismissed, UNIQUE(post,series)); migration 0041 + two settings
knobs (series_suggest_enabled, series_suggest_threshold).
- series_match_service: weighted additive score (title-stem / same-artist /
page-continuity / shared-distinctive-tags), no single signal gating. The title
"pattern" is derived on the fly from the post titles already in a series, so it
sharpens as more are confirmed (no persisted state to drift). Candidates are
bounded to the post's artist. match_post upserts pending suggestions (UNIQUE +
on-conflict, respecting prior added/dismissed decisions).
- accept reuses add_post_as_chapter then marks 'added'; dismiss marks 'dismissed'.
- rescan_series_suggestions_task: settings-gated, time-boxed + self-resuming from
a post-id cursor (maintenance_long lane), like normalize_tags_task.
- API: GET /series/suggestions, POST .../<id>/accept|dismiss, POST .../rescan.
- Settings: enabled + threshold exposed via /settings/import.

series — series tag named after the post, one chapter, the post's images as

- SeriesService.add_post_as_chapter: append a post as the next chapter of an
existing series, titled after the post and slotted by parsed page number
(a "pages 1-4" post lands ahead of the "pages 9-12" chapter).
- SeriesService.list_series: browse cards — cover thumb, artist, chapter/page
counts, gap flag, last-updated; sort recent|name|size + filter by artist.
- API: GET /api/series, POST /api/series/from-post, POST /api/series/<id>/add-post.
- Resolver uses ImageRecord.primary_post_id (same linkage the posts feed renders).
Frontend (Add-to-series control + Series view + nav) lands next.

Adds an ordered chapter layer to series. Reading order becomes
(series_chapter.chapter_number, series_page.page_number); a chapter may be a
placeholder reserving a slot, and carries an optional parsed stated-page range
used to flag missing-page gaps. An image still lives in at most one series ⇒ one
chapter (image_id stays UNIQUE).
- models: series_chapter; series_page gains chapter_id (NOT NULL, cascade) +
stated_page. Migration 0040 backfills every existing series into one
auto-chapter holding its current flat pages — no data loss.
- SeriesService: chapter CRUD (create/update/reorder/delete/merge), page→chapter
assignment, reorder_pages, chapter-aware set_cover; list_pages now returns
chapters[] + gaps[] alongside a back-compat flat pages[]. Legacy series-wide
reorder operates on the single default chapter and rejects multi-chapter series.
- API: chapter endpoints under /api/series/<tag>/chapters; POST pages accepts an
optional chapter_id.
- TagService.merge now repoints series_chapter too, so a merged series' chapters
(and their pages) survive the source tag's deletion instead of cascading away.
- Tests: new chapter suite; updated the 4 direct SeriesPage(...) constructions to
supply chapter_id.
Frontend (chapter-aware manage view + reader) lands next; until then the
existing UI keeps working via the flat pages[] + single default chapter.

Solid-color members phash-collapse to distance 0, so the second archive's member
deduped away ("held no supported members") and members_imported was 0. Use
structurally distinct patterned jpegs so both members import — the resume cursor
mechanics were already correct.

reextract_archive_attachments loaded ALL PostAttachments and ran in one pass up
to a 30-min soft limit, then died without re-enqueueing — a large archive
backlog would only ever partially process. And a naive re-run can't advance: an
already-extracted archive is still an archive on disk, so it'd re-extract the
same first batch forever.
Give it a real cursor + time-box + self-resume (mirrors normalize_tags_task,
operator-asked 2026-06-07: reasonable timeout, then re-queue so other work keeps
flowing):
- service scans attachments with id > after_id in ascending order, time-boxes
the chunk, and reports partial=True + resume_after_id (last scanned id).
- task passes a 600s budget and re-enqueues itself from the cursor until the
scan is exhausted. Routes on the maintenance_long lane.
- This is independent of the maintenance_long lane isolation (already shipped) —
that stops long tasks starving the quick maintenance queue; this stops the
re-extract itself dying on a big backlog.

Even chunked, a single concurrency-1 maintenance lane is fragile — a 30-min DB
backup or a multi-chunk library audit holds the slot and delays the quick
self-healing recovery sweeps / vacuum (operator-flagged 2026-06-07: long runs
must never block quick maintenance).
Route the long one-shots — backup.*, admin.* (normalize/re-extract/cascade-
delete), library_audit.* — to a new `maintenance_long` queue served by a
dedicated worker (concurrency 1), added to docker-compose (+ dev override). The
scheduler keeps the quick `maintenance` lane (sweeps, vacuum, cleanup) for
itself, so a backup can no longer starve a 5-min vacuum. UI queue list +
routing tests updated.

scan_library_for_rule ran one 2-hour pass that timed out on large libraries and
held the concurrency-1 maintenance queue the whole time, starving vacuum/backup/
normalize (operator-flagged — it was the dominant entry in the 24h failures).
It now runs ~10-min chunks and re-enqueues itself until the library is
exhausted, matching the operator's preferred pattern (reasonable timeout → retry
queued → other things process between). New columns (alembic 0039):
resume_after_id persists the keyset cursor so a chunk continues where the last
left off; last_progress_at lets the recovery sweep tell a progressing multi-
chunk audit from a dead one (it now measures staleness from last_progress_at,
not started_at). Matches accumulate across chunks. soft/hard limits dropped
2h→15/16.7 min so the in-chunk budget fires first; a soft-limit backstop
re-enqueues to resume instead of erroring the whole run.
Tests: time-box → re-enqueue (status stays running); resume carries prior
matches and appends new ones. Existing full-scan tests unchanged (small sets
finish in one chunk).

normalize_tags_task timed out at the 40-min hard limit on a large back-catalog
(the first run recases the whole booru vocabulary) — operator-flagged, and it
monopolized the concurrency-1 maintenance queue while doing so.
normalize_existing_tags now takes time_budget_seconds: the live run stops
cleanly at the budget and reports {partial, remaining}. The task runs 600s
chunks and re-enqueues itself until nothing remains (idempotent — commits per
group, so the next chunk skips already-canonical groups). Short chunks let the
recovery sweep and other maintenance tasks interleave instead of being blocked
for 40 minutes.
Frontend: the Standardize button is now fire-and-forget ("Queued — runs in the
background; re-run Preview to confirm") instead of poll-until-done, which would
have falsely reported "complete" after the first chunk.

The native client treated a gallery image without `file_name` as schema drift
and raised "Patreon API changed — ingester needs update", failing the whole walk
(operator-flagged 2026-06-07: BlenderKnight post 73665615, kind=images). But the
resource had a valid URL, and the code already derives a filename from the URL
basename right below the raise — the same fallback gallery-dl uses. Patreon
legitimately serves some images without file_name, so this isn't drift.
Drop the require_file_name gate from _media_item: file_name is now optional for
every kind (images/attachments/postfile), falling back to the URL basename.
Genuine drift still raises — no resolvable URL, or a media id referenced by a
relationship but absent from `included`. Test updated to assert the fallback.

The mid-post time-box check (619e771) reads time.monotonic() once more per post,
so test_backfill_budget_cut_returns_partial_with_progress's discrete tick
sequence shifted — the >budget tick (200) landed on post1's first-item check
instead of post2's gate, cutting post1 to 0 files. Add the extra tick (20, still
under budget) so post1's item downloads, matching production where the gate and
the first should_stop are microseconds apart.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
A backfill chunk's time-box (BACKFILL_CHUNK_SECONDS=600) was only checked
between POSTS, but download_post downloads ALL of one post's media
synchronously — so a single media-heavy post could run the chunk far past 600s,
all the way to the Celery soft time limit (1350s), where it was killed and
finalized as error (Pocketacer, event #41330: ran the full 22.5 min).
download_post now polls a should_stop() deadline BEFORE each media item and the
engine passes `now - start >= time_budget_seconds`, so a heavy post stops at the
budget and the remaining media (never marked seen) re-fetch next chunk. Bounds
chunk overrun to one media download instead of one whole post.
Also genericized the soft-limit salvage message — it claimed the "gallery-dl
subprocess" failed, which is wrong for a native Patreon walk; it now describes
the time-budget overrun + per-page checkpoint resume in platform-neutral terms.

A source URL like https://www.patreon.com/posts/mimic-in-dungeon-158372536 is a
single-post permalink, not a creator page — the resolver grabbed "posts" as the
vanity and failed (operator-flagged 2026-06-07). Add a resolution path: extract
the trailing post id and follow it to the owning campaign via the Patreon post
API (/api/posts/<id>?include=campaign), so pasting any post URL subscribes to
that creator's whole feed. `posts/` is excluded from the vanity regex so it
can't masquerade as a creator slug.
Resolution order is now: cached override → id: URL → /posts/<id> → vanity
(campaigns API + creator-page scrape). Tests cover the post→campaign resolve
and that /posts/ URLs aren't treated as vanities.

A new enabled source is armed for run-until-done backfill (#693) but would sit
idle until the next scheduler tick (~60s). create_source now enqueues the first
walk right away (pending DownloadEvent + download_source.delay), skipping only
when the platform is in a rate-limit cooldown (the scheduler picks it up when
that clears). Disabled sources still don't dispatch.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Two concurrent Patreon walks could trip the server rate limit even with each
source pacing its own requests. The platform-cooldown handled the aftermath of
a 429; this adds the preventive half — a per-platform Redis lock so only one
Patreon walk runs at a time. Different platforms still run concurrently up to
the worker concurrency; only a second walk on the SAME serialized platform
waits.
download_source acquires fc:download_lock:<platform> (non-blocking) before the
run. On contention it re-enqueues itself with a short countdown (the pending
event stays — no new event, no log spam), bounded to ~15 min then runs uncapped
as a safety valve. The lock TTL sits just past the hard kill so a SIGKILL'd
worker auto-releases; a backfill chunk only holds it ~10 min, well under the
30-min DownloadEvent recovery sweep. A broker hiccup degrades to uncapped
(prior behaviour) rather than stalling downloads. SERIALIZED_PLATFORMS={patreon};
gallery-dl platforms are left uncapped (self-pacing subprocesses).

A source URL like https://www.patreon.com/cw/Atole resolved vanity='cw' — the
vanity regex only skipped a /c/ prefix, so Patreon's current /cw/ ("creator
workspace") form fell through to the bare-vanity branch and captured the prefix
instead of the slug. Every /cw/ source then failed campaign-id resolution
(API + page-scrape both looked up "cw"). Operator-confirmed 2026-06-07 via the
new error text: source_url='.../cw/Atole'; vanity='cw'.
Add cw/ to the optional prefix group (ordered before c/ so the longer prefix
wins), and have the creator-page fallback try the /cw/ form too. Test covers
bare / c/ / cw/ extraction and that id: URLs stay non-vanity.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Patreon's /api/campaigns?filter[vanity]= lookup returns empty data for creators
that plainly exist (operator-flagged 2026-06-06 — Atole etc. erroring at the
resolve step). gallery-dl never used that endpoint; it pulls the campaign id out
of the creator page's bootstrap JSON. Add the same as a fallback: when the API
misses, GET the creator page (bare + /c/ vanity paths) and scrape the first
campaign id from any known embedding ("id":"…","type":"campaign" /
"campaign":{"data":{"id" / /api/campaigns/<id> / "campaign_id"). API is still
tried first (cheap, structured); the page scrape only runs on a miss.
Tests: API-empty → page-scrape fallback resolves; _scrape_campaign_id pattern
coverage. Existing API-path tests unchanged (happy paths short-circuit before
the fallback; failure paths hit the guarded scrape and still return None).

normalize_tag_name now only capitalizes the first letter of each word and
leaves the rest of the word untouched (was lowercasing the tail, which turned
DC→Dc / NSFW→Nsfw). This matches ml/tag_name._title_word, so a Camie-suggested
tag keeps the exact casing the suggestion UI showed when it round-trips through
POST /api/tags on Accept — addressing "auto-suggested tags must obey
capitalization" and "don't mangle acronyms" in one rule.
Trade-off (operator-chosen): all-caps input no longer folds to Title Case, so
case-variant merging in #714 still folds the dominant lowercase-vs-Title case
but leaves all-caps stylizations distinct (protecting acronyms wins). Tests
updated + a new test documenting acronym preservation / non-folding.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Follow-up to #701: new tags are saved canonical, but the back-catalog keeps
whatever casing it was created with. This adds a maintenance action that
Title-Cases every existing tag (collapsing whitespace) and merges
case/whitespace-variant duplicates into one.
Backend:
- tag_service.normalize_existing_tags(session, *, dry_run): groups all tags by
(kind, coalesce(fandom_id,-1), canonical_name). Per group it picks a survivor
(prefer an already-canonical member → no rename/self-alias; else the
best-connected tag → fewest FK repoints; else lowest id), merges the variants
INTO it via the tested TagService._do_merge (image_tag/allowlist/embedding/
aliases/series_page repoints + protective ML aliases), then renames the
survivor to canonical. Losers are deleted before the rename so there's no
transient unique-index clash; commits per group and isolates failures per
group. Idempotent — an already-canonical lone tag is a no-op.
- normalize_tags_task (maintenance queue, asyncio.run + per-task NullPool async
engine, soft 1800/hard 2400) — recovery/timeout/duration covered by FC-3i.
- POST /api/admin/tags/normalize: dry_run=true returns a projection inline
(group/collision/rename counts + sample); dry_run=false enqueues the task.
Frontend: a "Standardize tag casing" section in TagMaintenanceCard (Cleanup
tab) — preview → apply (polls the activity dashboard to terminal status),
behind a back-up-first warning. admin store gains normalizeTags().
Tests: tests/test_tag_normalize.py — dry-run counts, live merge + image-tag
dedup/repoint, idempotency, same-name-different-fandom and -different-kind kept
separate, ML-known loser keeps a protective alias.

normalize_tag_name (per-word capitalize + whitespace collapse) is applied in
the POST /api/tags handler so operator-entered tags get clean display casing.
It is NOT applied in the shared find_or_create / rename paths — those are used
by the ML tagger and allowlist matching, which must preserve the booru
vocabulary's original casing (Title-Casing it broke apply_allowlist matching).
find_or_create / rename keep case-insensitive lookup + clash detection so a
differently-cased entry dedups onto the existing tag instead of forking.
Tests updated to expect Title-Cased create output (sunset→Sunset,
character:Saber→Character:saber, http://example.com→Http://example.com) and a
dedicated normalize_tag_name unit test.

Now that we own the walk, surface live counts on the in-flight download in the
Downloads view. ingest_core.run takes an event_id and does a TIME-THROTTLED
write (~5s, decoupled from page boundaries so it ticks steadily regardless of
how big/slow a page is) of {downloaded, skipped, errors, quarantined, posts} to
the running download_event's metadata.live (jsonb_set; short session; status
guard so a finalized event isn't clobbered). download_backends threads
event_id from ctx; the /api/downloads list surfaces `live`; ActiveDownloadsPanel
renders it beside the elapsed timer. Native (Patreon) only — gallery-dl is an
opaque subprocess; the row only shows when `live` is present. Phase 3 overwrites
metadata with run_stats on finish, dropping `live`.
Test: _write_live_progress updates a running event's metadata.live and leaves a
finalized (status != running) event alone.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Tags now normalize to Title Case + collapsed whitespace at the central
TagService.find_or_create (and rename) — so manual entry, the create API, and
anything routed through find_or_create produce the canonical form. The lookup is
case-insensitive, so a differently-cased entry finds the existing tag instead of
forking a case-variant duplicate ('hatsune miku' / 'HATSUNE MIKU' → one tag).
normalize_tag_name uses per-word capitalize (not str.title(), which mangles
apostrophes) and folds ALL-CAPS input. Existing tags keep their current casing
until touched — a retro-normalize maintenance pass (Title-Case + merge
case-collisions) is the follow-up to convert the back-catalog.
Test: create title-cases + collapses whitespace; case/whitespace variants dedupe
to one tag.
