- Dual sign-off is now the default (thesis_required_approvals defaults to 2).
- Entity-merge review queue (migration 0003): the fuzzy/Qwen tier no longer
auto-merges — it writes CANDIDATES (entity_merge_candidates) with a same/different
suggestion + confidence + reason for a human to approve (merge) or reject (keep
separate). entity_merge.py applies/rejects (durable via entity_merges, soft-delete,
repoint links+edges); decided pairs aren't re-surfaced.
- entity_jobs.py: UI-triggered background index jobs (rebuild/update/find-duplicates)
as subprocesses with a one-at-a-time lock; status in /api/system/status.
- server.py: /api/index/{rebuild,update}, /api/entities/find-duplicates,
/api/entities/merge-candidates [+ /{id} decide] — admin-gated.
- docs/thesis-seed-v2.md: concrete, plain-English rewrite per Grant's feedback.
Backend verified end-to-end on synthetic data (candidate gen -> approve/reject).
