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Drops the unused tag.namespace column from FC-1 — superseded by kind.

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.

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