bvandeusenandClaude Opus 4.8	fac5ae6ce5	feat(explore): reach dial to escape dense clusters + anti-revisit (#1476) ... The Explore walk got stuck in dense signatures — neighbours all too similar, so forward-arrow couldn't escape and Random was the only exit. Root cause: MMR only diversifies WITHIN the nearest ~400 pool; in a dense cluster that whole pool is near-identical, so there's no escape route in it. - gallery_service.similar(reach=0.0, exclude_ids=None): reach>0 widens the pool (cap 400→1000) and _reach_sample strides across an outward-growing distance span so the set handed to MMR spans near→mid-far (guaranteed escape routes), not just the tight cluster. exclude_ids drops already-walked images. Gallery 'more like this' (reach=0) is unchanged. - api/gallery similar: parse reach + exclude_ids. - explore store: default reach 0.4 (auto-diversifies without touching the dial), pass the breadcrumb as exclude_ids, setReach action. - ExploreView: a Near↔Far reach slider in the trail. - tests: _reach_sample math (deeper ranks with higher reach, near kept); similar exclude_ids drops walked + reach path runs clean.

bvandeusenandClaude Opus 4.8	f8105046dc	feat(explore): exclude WIP-tagged work from the Explore rabbit-hole ... 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.

bvandeusenandClaude Fable 5	723f023e6a	feat(gallery): similar() hides presentation images (banner / editor screenshot) ... Step 3 of milestone #128. Presentation-tagged images cluster on UI chrome rather than content, so near any one of them they fill the whole more-like-this grid. Excluded from candidates in the ONE whole-image similarity surface (gallery similar mode, explore walk, and RelatedStrip all ride GalleryService.similar) — the anchor itself may be a banner, and wip stays surfaced: only the training pipelines exclude it.

bvandeusenandClaude Opus 4.8	0f472b2f9e	fix(explore): diversify "more like this" so it stops getting stuck (#1188) ... Pure nearest-cosine piled near-identical images into the neighbour grid — a reposted banner filled all 24 slots, and once you wandered into a B&W / comic-panel cluster every neighbour was more of the same with no way back to colour without the Random button (operator-reported, with screenshot). similar() now over-fetches a wide candidate pool (5x the requested limit, cap 200), then diversifies down to `limit`: - pHash near-duplicate collapse: drop candidates within 6 Hamming bits of the anchor or an already-kept candidate, so a repost (and the anchor's own clones) appears at most once. - MMR re-rank: greedily pick for closeness-to-anchor minus similarity-to-already -picked (lambda 0.55), so the result SPANS clusters instead of returning 40 variations of one image. Falls back to nearest-order on any failure / small pool, so existing nearest-first behaviour is unchanged when there's nothing to diversify. Frontend forwardTarget drops the now-redundant skip-nearest-third hack (the list is already diversified server-side) — plain random-over-unvisited gives the variance now.

bvandeusenandClaude Opus 4.8	79cd1234e2	feat(gallery): visual 'more like this' search (Phase 3 backend) ... 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. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-04 08:47:43 -04:00
