POST /v1/uploads (Task 18, A03): @@unique(userId, clientTaskId) idempotency anchor — same params return the original session (201, no duplicate photo); param drift (album/bytes/contentType/extension) -> 409 UPLOAD_SESSION_CONFLICT. photos.objectKey is set to the FINAL originals key at init while the session holds the staging key; IDs come from an app-side cuid-like generator so both self-referencing keys are written in one transaction. Credential is a real MinIO presigned PUT (SIGNED_URL_TTL_SECONDS, lazily read). Permission order: album invisible 404 -> member 403 -> uploadEnabled 409 -> size/ext 400 -> category ownership 400. No audit on init (audit anchors on complete). Pre-step for Task 19: QUEUE_PHOTO_PROCESS contract constant + lazy-safe BullMQ queue producer (Redis down at boot must not crash the app; enqueue failure only logs — sweep compensates). e2e reset now also wipes the MinIO photo-live/dev prefix; jest maps @photo/storage to TS source.
