feat(faces): let the photographer choose which photo represents a person (#1119)
Phase 1 of #1096. Clustering picks the cover, and its idea of a good one and a human's do not always agree. A cluster whose avatar is turned away or softer than the rest stays that way in the guest-facing people strip too, and nothing in the UI could change it. A picker reachable from each person row, reusing the face list the split dialog already loads — same query, same grid, different action on a click. Making the choice actually stick took four changes --------------------------------------------------------------------------- event_people.cover_face_id has existed since migration 177 and the PATCH already accepted it, so the first version of this was frontend-only. It was also a no-op: - facePeopleService.listPeople SELECTED cover_face_id and then discarded it, recomputing the cover as the best-scoring VISIBLE face on every read. The picker saved, said so, and the avatar reverted immediately. It now prefers the stored pick whenever this audience can see it, and falls back to the score-ordered choice otherwise — so visibility scoping still wins, and a guest is never handed a crop of a photo they cannot open. - recomputeCentroid overwrote cover_face_id unconditionally. It runs on rescan and on photo replacement, so any reprocessing silently undid a deliberate choice. It now keeps the chosen face while it is still a member of the cluster. - The face list is cached per person, and split/merge move faces between people. Until now the only reader closed itself after acting, so nobody saw the stale copy; the picker is a second reader of the same key. - cover_face_id meant two things. assignFaces seeded it with whichever face opened the cluster and recomputeCentroid overwrote it with the highest scoring one, so an automatic guess was indistinguishable from a deliberate choice — and honouring it would have pinned every UNCURATED person to that guess, which is worse than the fallback it replaced (the fallback is computed per audience and skips photos a guest cannot open). Both writers are gone, migration 179 clears the stored guesses, and the column now means one thing. That also removes the need to defend the choice against rescans: nothing overwrites it, and a dangling id self-heals to the derived cover. Clearing existing values is safe rather than destructive: no install has ever been able to SET a cover, so every stored value is an automatic guess by construction. Also fixes a PostgreSQL-only 500 --------------------------------------------------------------------------- GET /admin/events/:id/people/:personId/faces joined `photos` but did not table-qualify its WHERE, and photo_faces and photos BOTH have an event_id: column reference "event_id" is ambiguous Postgres refuses it, so the endpoint 500s and the Split dialog — its only consumer until now — has been broken on every PostgreSQL install since the join was added. SQLite resolves the ambiguity silently, which is why the suite stayed green. Reproduced against a real Postgres before and after. The query is now a named builder the route calls and the test imports, rather than a copy: an earlier version of that test re-declared the query, so the route could regress to the bare form while the assertions kept passing. Merge and recluster preserve the choice as well. Both already carried labels and privacy flags across; the chosen cover is human state of the same kind, so it now rides along — through a merge when the target has none, and through a recluster by following its FACE into whichever cluster ends up holding it, rather than the majority-descendant rule the label uses. The picker and the endpoint disagree past 500 faces, so the picker now says when it is showing a capped list rather than presenting it as exhaustive. Frontend suite 178 passing, backend 23 across the touched suites, build clean, no new type errors. Mutation-checked twice: dropping the cover preference fails the new listPeople test while the visibility-scoping test still passes, and restoring the auto-seed in assignFaces fails it too. |
