A 422 from Apollo's /encode_image (bytes it can't decode — corrupt
files, non-images with an image extension) left clip_embedding NULL,
so the drain re-sent the file and logged the same "permanent failure
(will retry next pass)" on every scan.
Permanent rejections now record a clip_failures marker scoped to the
row's content_hash; list_clip_unencoded_candidates skips the row while
the hash still matches, so a replaced file gets another try with no
cleanup. Only 422 (new ClipError::Rejected) marks: other 4xx are
deployment problems (auth, routing) and would otherwise blacklist the
whole library.

The CLIP encode failure reason was only ever returned in the HTTP response
body, never logged server-side, making 502s from /photos/search opaque. Log
the underlying cause — network error to the URL, or the Apollo HTTP status +
response body — so CLIP-service problems are diagnosable from the ImageApi log.

Pulls cargo fmt + clippy pass over the new files only — pre-existing
files left untouched even though fmt has drift on them. clamp(1,200)
swaps a manual min/max chain that clippy flagged. test AppState
constructor needed ClipClient::new(None) so the lib-test target
compiles.

Probe-phase scaffolding for CLIP semantic search. Adds the column
that will hold per-photo embeddings, the HTTP client to Apollo's
inference service, and a throwaway probe binary so we can eyeball
search-result quality on the live library before building the
persistence layer (backlog drain, /photos/search endpoint, UI).
- migrations/2026-05-14-000000_add_clip_embedding/ — adds
image_exif.clip_embedding (BLOB) and clip_model_version (TEXT),
plus a partial index on (clip_embedding IS NULL AND content_hash
IS NOT NULL) for the future backfill drain.
- src/database/models.rs — extends ImageExif struct to match.
- src/ai/clip_client.rs — encode_image / encode_text / health,
same Permanent/Transient/Disabled taxonomy as face_client.
- src/bin/probe_clip_search.rs — --query <q> --library N --limit M
--top K. Encodes a sample and prints top-K cosine similarities.
No DB writes.
