Autoscaler (agent 2026-07-02.5): the buffer-occupancy signal alone would peg
downloaders at DL_MAX while the bandwidth CAP — not concurrency — is the real
constraint (8 streams sharing 8 MB/s move no more data than 4). Growth is now
gated on the pipe having headroom (net < 85% of cap) and a pipe pinned at the
cap (>= 95%) sheds streams down to 3; dead band prevents flapping. The UI hint
says 'holding at the bandwidth cap' and /status reports bw_capped, so the
behavior is legible without tests that need the ML stack.
Reset content tagging: stays a FULL-instance reset (operator's call), but now
lives in a fenced 'Danger zone' section on Cleanup and the apply is gated by a
preview-derived confirm token (mirrors the Tier-C bulk-delete pattern — stale
counts are rejected server-side). Copy no longer claims suggestions repopulate:
it says plainly the heads' training examples are deleted and re-tagging starts
fresh. Moved out of TagMaintenanceCard into DangerZoneCard.

- ml-backfill-daily: the CPU tag_and_embed backfill raced the GPU agent's
daily embed backfill for the same NULL-embedding images at ~100x the cost
(B1 audit verdict, milestone #124). The backfill TASK stays — the manual
/api/ml/backfill button remains the deliberate CPU fallback pending B3.
- purge-legacy: one-time IR-migration cleanup, dry-run verified 0 targets on
the live library before removal (A2 audit, milestone #123). Fully retired
per rule 22: tile, store action, route, service fn, tests.

Cluster B frontend, milestone #99.
#7c: AllowlistTable gains Applied + Covers columns and a live 'covers ~N at T'
projection as the operator drags a row's threshold (debounced coverage call,
then commits the threshold). allowlist store gains coverage(tagId, threshold)
and refreshes coverage_count after a save.
#7d: suggestions store surfaces a non-blocking toast when accept/alias newly
allowlists a tag — '<verb>: <tag> — allowlisted, auto-applying to ~N images'
(N is the projection; apply runs async). Falls back to the plain toast when
the tag was already allowlisted.
#8b: TagsView merge picker now previews the merge via usePreviewCommit before
committing — shows images moving / already-on-target / series pages / alias-or-
delete / a thumbnail sample, blocks the Merge button on an incompatible
kind/fandom. adminStore.mergeTags gains a dryRun option.

DRY pass follow-up (note #1026). All 13 admin-store actions repeated the same
lastError-capture/rethrow wrapper; the 6 Tier-A maintenance actions additionally
repeated the dry_run POST shape.
- _guard(fn): one copy of the lastError=null / try / catch(set lastError; rethrow)
wrapper, used by all 13 actions.
- _dryRunPost(url, {dryRun, ...extra}): the dry_run POST shape on top of _guard,
used by the 6 maintenance actions. reconcile maps sourceId -> source_id.
Public exports + every action signature unchanged (object-opts for Tier-A,
positional for cascade/bulk/tag ops), so no card/view changes. Behavior identical.
Added frontend spec (the admin store had none): _dryRunPost endpoint+body+default,
sourceId->source_id mapping, and _guard capturing lastError + clearing on success.

An artist first downloaded by gallery-dl gets Post rows keyed by the per-
attachment id; a later native walk keys the SAME real post by the post id. They
never dedup (uq_post_source_external_id is on external_post_id) → duplicate post
rows (cheunart: 943→1109). The real post id is recoverable in-DB from
raw_metadata['post_id'] (both eras store the sidecar there).
reconcile_duplicate_posts (cleanup_service): group posts by (source_id, canonical
post_id = raw_metadata.post_id else external_post_id); for each group >1, keep the
row already keyed by the post id (the format the CURRENT native downloader
produces, so future walks dedup and this can't recur), re-point
ImageRecord.primary_post_id / ImageProvenance / PostAttachment / ExternalLink onto
it conflict-safe (drop the loser's row where the keeper already has the equivalent,
per each table's uniqueness), backfill the keeper's empty date/title/body/raw_meta
from a loser, set external_post_id=post_id + derive post_url, delete losers.
IMAGES ARE NOT TOUCHED (content-addressed/deduped already; operator-confirmed).
Preview/apply share find_duplicate_post_groups (rule 93). API
/api/admin/posts/reconcile-duplicates (dry_run→{groups,posts_to_merge,sample};
apply→{groups,merged,sample}; optional source_id). UI: a second section on
PostMaintenanceCard (preview groups+sample → confirm merge). Tests: merge +
metadata backfill + image move, no-op when unique, provenance-collision dedup.
Design: milestone #73. Forensics: note #917. Out of scope (flagged): cheunart vs
Cheunart case-variant artist dirs/rows.

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.

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.

Wipe every general + character tag so the operator can re-tag from scratch via
the Camie auto-suggest, while PRESERVING fandoms, series (+ series_page order),
and each image's stored tagger_predictions (so suggestions repopulate
immediately). One set-based DELETE FROM tag WHERE kind IN ('general','character')
— the five tag-referencing tables all cascade, so applications + aliases +
allowlist + rejections + centroids clear automatically; series tags aren't
deleted so series survive; Tag.fandom_id is SET NULL so fandoms are untouched.
Reuses the established dry-run-preview -> confirm pattern: cleanup_service.
reset_content_tagging() + POST /api/admin/tags/reset-content +
TagMaintenanceCard section with a backup-first warning and a red confirm
showing exact counts (tags by kind + image applications). Irreversible except
via DB backup restore; the wipe only fires when the operator confirms.
Tests: service dry-run counts + live delete preserves fandom/series/series_page
while content tags + their image_tag cascade away; API dry-run wiring.

Operator-confirmed 2026-05-28: the BlenderKnight:* tags are `archive`
kind (caught by the kind purge), but the `source:patreon`-style tags
are IR's old `source` kind that fell back to `general` during migration
(FC's enum has no `source` kind) — so they can't be matched by kind.
Broadened the purge to a two-rule match and renamed it for accuracy
(all dev-only, unreleased):
- cleanup_service.purge_tags_by_kind → purge_legacy_tags. Predicate is
now `kind IN (archive, post, artist) OR name LIKE 'source:%'`
(LEGACY_NAME_PREFIXES). Preview classifies each row into by_kind OR
by_prefix (source:* counts once under the prefix bucket regardless of
its general kind).
- endpoint /tags/purge-retired-kinds → /tags/purge-legacy. dry-run
returns by_kind + by_prefix + count + sample.
- store purgeRetiredKindTags → purgeLegacyTags.
- Tag Maintenance card copy + breakdown updated to show both buckets;
button reads "Preview/Delete legacy tags".
Tests updated + extended: dry-run reports by_kind {archive,post,artist}
AND by_prefix {source:*}, plain general/character tags survive; commit
deletes both the kind-matched and source:*-matched rows and leaves the
rest.
Operator-flagged 2026-05-28, two asks.
**1. Provenance posts ate the panel.** Each post card rendered its full
description (180px scroll box) inline, so a few posts pushed everything
else off-screen. ProvenancePanel now collapses the description by
default behind a per-post "Show description ▾ / Hide ▴" toggle (state
keyed by provenance_id, reset when the viewed image changes). Cards stay
compact — platform/date/title/meta/actions — and the operator expands
only the descriptions they want.
**2. Purge tags of retired/system kinds.** The IR migration left
`archive`/`post`/`artist`-kind tags (e.g. `BlenderKnight:Hannah_BJ_Loops`)
that FC no longer creates — the tag input only makes
character/fandom/series/general, and provenance + artists are their own
systems now. (meta/rating were already hard-deleted by alembic 0023.)
- cleanup_service.purge_tags_by_kind(kinds=PURGEABLE_TAG_KINDS) — counts
(dry_run) or deletes tags whose kind ∈ (archive, post, artist).
CASCADE clears the image_tag / alias / allowlist / etc. rows.
- POST /api/admin/tags/purge-retired-kinds (Tier-A, dry-run preview
returns per-kind counts + sample names — the preview IS the
verification of exactly what'll be deleted before committing).
- Tag Maintenance card gets a second section: "Preview retired-kind
tags" → per-kind breakdown + sample → "Delete N retired-kind tag(s)".
Tests: dry-run counts by kind (general survives), commit deletes only
the retired kinds (general + character survive, retired count → 0).
NOTE: a dry-run preview will show exactly which kinds/counts are
present. If the operator's noisy tags turn out to be `general` (e.g. an
IR `source:patreon` that fell back to general during migration), they
won't be caught by the kind purge — the preview makes that visible so
we can decide on a name-based pass separately.
