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.

recover_interrupted_tasks runs every 5 minutes, finds ImportTask rows
stuck in 'processing' for >30 minutes (well above any legitimate import
duration), and re-queues them. cleanup_old_tasks runs daily and deletes
finished tasks older than 7 days so the task table stays an operational
view rather than an archive.
Both thresholds match ImageRepo's precedent. The 30-min stuck threshold
is documented inline so a future reader can adjust it intentionally
rather than mistaking it for a 'magic number'.

scan_directory walks ImportSettings.import_scan_path, creates an
ImportBatch, enumerates supported files into ImportTasks, and enqueues
import_media_file per task. import_media_file moves the task through
its state machine (pending → queued → processing → complete/skipped/failed),
updates ImportBatch counters atomically (UPDATE ... SET col = col + 1),
enqueues a thumbnail task on success, and marks the batch complete when
the last task drains.
generate_thumbnail runs on its own queue (thumbnail) so big imports
don't starve thumbnail throughput; failure here is logged and does not
fail the import.

Cursor format: base64(iso8601_created_at|image_id). Pagination key is
(created_at DESC, id DESC) so we don't drift when new imports land between
page loads. Timeline groups by date_part(year, month) so the sidebar can
render year-month jump buckets. get_image_with_tags returns full image
detail plus prev/next ids so the modal viewer can navigate without an
extra round-trip per arrow press.

Single-file pipeline: validate as image, apply filter rules (min dimensions,
transparency), SHA256 hash dedup, atomic copy to /images/{subdir}/, create
ImageRecord with origin='imported_filesystem' and integrity_status='unknown',
auto-derive top-level folder name as Artist + artist tag.
Importer is intentionally sync (consumed by a Celery worker process); the
async Quart side uses the same ORM through its own async session. The
db_sync fixture in conftest.py was added in Task 3 to support these tests.
Thumbnail generation is NOT inlined; the calling Celery task enqueues a
separate thumbnail task so the import queue keeps moving on big batches.
pHash dedup is FC-2d, not here.

Generates 400px-max thumbnails: PNG with alpha preserved when source has
transparency, JPEG (q=85, progressive) otherwise. Storage layout is
/images/thumbs/{sha[:3]}/{sha}.{jpg|png} so each prefix bucket holds at
most ~4k files (16^3 buckets across all possible SHAs).
Video path uses ffmpeg's first-frame snapshot at ~5% offset; we have a
1-second floor for short clips. ffmpeg call has a 60s timeout. Video
tests are deferred to FC-2e's integration suite where transcoding is
also wired up.

Validates kind/fandom rules at the service layer: fandom_id only allowed
for kind='character', and must reference an existing kind='fandom' tag.
Autocomplete ranking: exact match > prefix match > substring, tie-broken
by image_count descending. Image-tag association uses INSERT ON CONFLICT
DO NOTHING for idempotent re-tagging.
conftest.py adds a transactional AsyncSession fixture; each test rolls
back so they don't pollute each other. Also includes a sync Session
fixture (db_sync) for the Importer tests in Task 5.

slugify() produces ASCII-only lowercase slugs from arbitrary text (used for
artist slugs and tag slugs). paths.derive_subdir/derive_top_level_artist
extract the destination layout and folder→artist convention from an import
source path. hash_suffixed_name builds IR-style 'stem__hash10.ext' filenames.

Adds Tag.kind enum (artist/character/fandom/general/series/archive/post/meta/rating),
Tag.fandom_id FK with CHECK constraint (only valid for kind='character'), and a
kind-aware uniqueness index so the same name can exist across kinds and the same
character name can exist in different fandoms.
Adds ImportBatch + ImportTask state-machine tables for scan tracking, plus a
single-row ImportSettings table (CHECK id=1) holding the importer's filter knobs.
Adds image_record.integrity_status column (defaults to 'unknown'); FC-2e
populates this via the integrity verifier.
Drops the unused tag.namespace column from FC-1 — superseded by kind.

The frontend blueprint is registered after the api blueprint so /api/*
routes are matched first; everything else falls through to the SPA.

Routes are pre-declared for FC-2/FC-3 task modules (import, ml, thumbnail,
download, scan, maintenance). Queue lanes match the ImageRepo pattern where
beat+maintenance run on a separate worker so long imports don't starve
periodic tasks. Smoke ping task confirms the wiring in eager mode for CI.

Implements the data model from spec §3 in one go so FC-2/FC-3 don't need
schema-adding migrations of their own. Artist is the unified entity for
both gallery 'artist:' tags and GallerySubscriber Subscriptions
(is_subscription flag). ImageProvenance is many-to-one, enabling the
enrich-on-duplicate rule for downloaded content that pHash-matches an
existing record.
The SigLIP embedding column uses pgvector(1152) for SigLIP-so400m;
swapping models in FC-2 will require a column-width migration.

Configures stable constraint naming so autogeneration produces clean diffs.
Alembic uses the sync psycopg driver while the runtime app uses asyncpg.
Also fixes a .gitignore bug caught during this task: the bare 'models/'
rule for the ML weights volume was matching backend/app/models/ (Python
package). Anchored all volume rules to repo root (/images/, /import/,
/downloads/, /models/, /postgres_data/, /redis_data/).

Config reads from env vars (12-factor); .env.example documents defaults.
Health endpoint is liveness-only (no DB/Redis touch). Test added for CI.

Pins runtime and ML deps separately so the regular web image stays lean.
Configures ruff for py312 with bugbear, async, and pyupgrade lints enabled.
psycopg sync driver included up-front for alembic.
