Explore's neighbour grid (/api/gallery/similar → gallery_service.similar) now
takes an Explore-only exclude_wip flag that drops `wip` system-tagged images
from the candidates, alongside the banner/editor presentation tags. The
gallery's own "similar" button is unchanged (keeps wip, #1274) — only the
Explore store passes exclude_wip=1. The anchor itself may still be a WIP; only
neighbours are filtered.

GET /api/gallery/hidden-review lists unresolved presentation auto-hide flags
(image + presentation tag + conflict tag/score), most-concerning first. POST
.../keep resolves the flag (the tag stays). POST .../unhide removes the
presentation tag (image returns to the gallery), records a TagSuggestionRejection
so the head learns it misfired, and resolves the flag. Tests for list/keep/unhide.
Frontend review strip (shown when Show-hidden is on) next.

The /similar route splats **filters into similar(), which doesn't take the new
include_hidden kwarg → TypeError → 500 (test_gallery_similar). Drop it like
post_id; similar() has its own presentation exclusion (#1274), so the
gallery-browse flag doesn't apply there.

The default gallery + facets now implicitly exclude images carrying a
presentation system tag (banner / editor screenshot), reusing the tag-scope
EXISTS machinery. Suppressed when the operator explicitly filters FOR a
presentation tag OR passes include_hidden (the Hidden view — step 2). `wip` is
NOT hidden (real, in-progress art). include_hidden threaded through
scroll/timeline/jump_cursor/facets + the gallery API _parse_filters. Test covers
default-hide, include_hidden, explicit-filter-shows, and wip-stays-visible.

The gallery's newest/oldest sort keys off image_record.effective_date =
COALESCE(primary post's post_date, created_at). The primary post is often the
repost/download the file came from, so the grid led with download dates rather
than when content was first posted (operator-flagged).
Add a second materialized sort key, earliest_post_date = MIN(post_date) across
ALL of an image's provenance posts (every post it appears in), else created_at —
the original publish date. Mirrors the effective_date pattern so the sort stays a
forward index scan.
- alembic 0071: add earliest_post_date + index (DESC, id DESC); backfill
created_at baseline then MIN over image_provenance ⋈ post.
- importer: recompute earliest_post_date whenever a dated post is linked (MIN over
the image's provenance, which now includes the just-added row).
- gallery_service: new sorts posted_new / posted_old key off earliest_post_date;
cursor + year/month grouping follow the active column transparently.
- api: accept posted_new|posted_old; DEFAULT is now posted_new so the grid leads
with original publish date. newest/oldest (effective_date) still available.
- frontend: sort dropdown gains "Newest/Oldest post date" (default Newest post
date); existing effective-date sorts relabelled "Newest/Oldest added".
- tests: service test asserts posted_new/posted_old key off earliest_post_date;
frontend default-sort omission test updated.

Cluster A, milestone #97. #5: clicking an image-modal tag chip's body now
closes the modal and opens the gallery filtered for that one tag (fresh
filter); ✕/kebab stay as the explicit remove/rename controls.
#6a (backend of OR/exclude filtering): gallery_service._apply_scope gains a
structured tag model — tag_or_groups (AND-of-OR: one EXISTS(tag_id IN group)
per group) + tag_exclude (NOT EXISTS(tag_id IN exclude)) — layered additively
on the existing tag_ids AND path so cursors/facets/deep-links are untouched.
Threaded through scroll/timeline/jump_cursor/facets/similar + facets common
dict; _require_single_filter rejects post_id combined with OR/exclude. API
parses tag_or (repeatable → one OR-group each) + tag_not (csv exclude).

GalleryService.similar() ranks images by pgvector cosine distance to a source
image's precomputed SigLIP embedding — no query-time ML inference. Composes
with the Phase-1/2 scope filters (AND) but replaces the date sort (always
nearest-first, bounded top-N, no cursor). Returns None for a missing source
(→404), [] for a source with no embedding (video / pending ML); excludes self
and NULL-embedding rows. New GET /api/gallery/similar?similar_to=<id>&limit=N.
Image-detail payload gains has_embedding so the UI can hide the surface.
Alembic 0036 adds an HNSW vector_cosine_ops index on siglip_embedding (1152<2000
dims) so the search is sub-50ms ANN instead of a full scan; one-time ~30-60s
build over existing embeddings on deploy. Shared _gallery_images/_image_json
helpers de-dup the scroll/similar builders.

Extend the composable gallery filter with platform / untagged / no_artist /
date_from / date_to, AND-composed with the existing tag/artist/media/sort
params and threaded through scroll, timeline, and jump_cursor.
Add GalleryService.facets() + GET /api/gallery/facets returning live counts
scoped to the current filter with per-group minus-self semantics: platform
counts (COUNT(DISTINCT image) incl. a null unsourced bucket), curation-flag
counts (untagged / no_artist), and effective_date min/max bounds. The
UNSOURCED_PLATFORM sentinel makes filesystem-imported content reachable via
the platform facet.

Phase 1 backend for the gallery filter bar. Extends scroll/timeline/jump
from a single mutually-exclusive filter to a composable one:
- tag_ids: image must carry ALL of them (one correlated EXISTS per tag —
AND, no row multiplication), replacing the single-tag JOIN.
- artist_id composes with tags; media_type ('image'|'video') narrows by
mime; post_id stays the exclusive post-detail path.
- sort ('newest'|'oldest') flips the effective_date/id cursor comparison
and ordering; the cursor value is unchanged (direction comes from the
request). jump_cursor honors sort too.
- Shared _apply_scope helper applied across scroll/timeline/jump so the
timeline sidebar reflects the filtered set. API _parse_filters parses
tag_id (comma list), artist_id, media, sort.
Tests: multi-tag AND, media filter, sort reversal (service + API);
post_id-excludes-others; single tag_id back-compat.

Five small G5 findings from the 2026-06-02 audit. Each is local and
follows an established FC pattern.
- download_service: replace hardcoded ('discord','pixiv') tuple with
auth_type_for(platform) == 'token'. A 7th token-platform now picks
up the right credential path without touching this site.
- /api/tags/<source_id>/merge enqueues recompute_centroid.delay after
merge so the target's centroid reflects its new image set
immediately. Daily list_drifted catches it within 24h, but eager
recompute closes the suggestion-quality dip in the meantime.
- backfill_thumbnails added to beat_schedule (daily). The task
docstring claimed periodic Beat but the entry was never registered,
so the library got no self-healing thumbnail repair; only the
manual admin-UI button fired it.
- modal.createAndAdd pushes a kind='fandom' tag into
tagsStore.fandomCache so FandomPicker sees the new fandom on next
open. Was: cache-gated load (length===0) skipped refetch, new
fandom invisible until full page reload.
- cleanup cluster:
- Drop .webp from cleanup_service.unlink — thumbnailer only writes
.jpg/.png; the third tuple member was dead code.
- Drop effective_date from /api/gallery/scroll response — no FE
consumer reads it. Service still computes the attribute for
timeline ordering; this just trims the JSON.
- Rename store.recentMinute → store.recentRuns across the
systemActivity store + three consumers (SystemActivitySummary,
QueuesTable, SystemActivityTab). The data is the last 200 runs
(not actually "last minute"), so the name lied.
NOT in this bundle: the duplicate tag-merge endpoint
(/api/tags vs /api/admin/tags) is harder — has 1 FE caller and 3 tests
on the admin variant; consolidation is its own change.
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
* timeline() year/month group-by
* jump_cursor() year/month filter
* _neighbors() prev/next ordering
- 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).

Thin Quart blueprint that delegates to GalleryService. Cursor-based scroll
returns images + a date_groups summary so the SPA can render year-month
headers without re-grouping client-side. Timeline returns year-month
buckets for the sidebar jump nav. Jump returns a cursor positioned at a
specific year-month so the gallery can scroll to historical periods.
