Merges develop (#820 version sync, #785 strip_noise + NORMALIZE_VERSION, #784 file locking) and addresses six concerns surfaced during PR review of the closet feature: 1. Closet append-on-rebuild bug — upsert_closet_lines used to APPEND to existing closets (mismatched the doc's "fully replaced" promise). With NORMALIZE_VERSION rebuilds on develop, this would have stacked stale v1 topics on top of fresh v2 content forever. Fix: - Drop the read-and-append branch from upsert_closet_lines (now a pure numbered-id overwrite). - Add purge_file_closets(closets_col, source_file) helper that wipes every closet for a source file by where-filter. - process_file calls purge_file_closets before upsert on every mine, mirroring the existing drawer purge. 2. Searcher returned whole-file blobs from the closet path while the direct path returned chunk-level drawers. Refactored: - _extract_drawer_ids_from_closet parses the `→drawer_a,drawer_b` pointers out of closet documents. - _closet_first_hits hydrates exactly those drawer IDs (chunk-level), not collection.get(where=source_file) (which returned everything). - Same hit shape as direct-search path; both now carry matched_via. 3. max_distance was bypassed on the closet path. Now applied per-hit; when every closet candidate gets filtered, _closet_first_hits returns None and the caller falls through to direct drawer search. 4. Entity extraction caught sentence-starters like "When", "The", "After" as proper nouns. Added _ENTITY_STOPLIST (~40 common false positives + day/month names + role words). Real names like Igor / Milla still survive — covered by tests. 5. CLOSETS.md drifted from the code (claimed "replaced via upsert" but code appended; claimed BM25 hybrid that doesn't exist; claimed a 10K char hydration cap that wasn't enforced). Rewritten to describe what actually ships, with explicit notes on the BM25 / convo-closet follow-ups. 6. Zero tests for ~250 lines. Added tests/test_closets.py with 17 cases: - build_closet_lines: pointer shape, header extraction, stoplist filtering (with regression case for "When/After/The"), real-name survival, fallback-line guarantee, drawer-ref slicing. - upsert_closet_lines: pure overwrite semantics (regression for the append bug), char-limit packing without splitting lines. - purge_file_closets: scoped to source_file, doesn't touch others. - End-to-end miner rebuild: re-mining a file with fewer topics fully purges leftover numbered closets from the larger first run. - _extract_drawer_ids_from_closet: parsing + dedup edge cases. - search_memories closet-first: fallback when empty, chunk-level hits with matched_via, no whole-file glue, max_distance enforced. Merge resolutions: miner.py imports combined NORMALIZE_VERSION/mine_lock from develop with the closet helpers from this branch. process_file auto-merged cleanly (closet block sits inside develop's lock body). 724/724 tests pass. ruff + format clean under CI-pinned 0.4.x.
