- Hall detection — routes drawer content to `emotions` / `technical` / `family` / `memory` / `identity` / `consciousness` / `creative` halls, enabling hall-based graph connectivity within wings (#835)
### Bug Fixes
- Repair `max_seq_id` corruption caused by `_fix_blob_seq_ids` misinterpreting chromadb 1.5.x's sysdb-10 BLOB format (`b'\x11\x11'` + ASCII digits) as legacy 0.6.x big-endian BLOBs. The shim now skips the `max_seq_id` table entirely and guards the `embeddings` branch with a prefix check. New subcommand `mempalace repair --mode max-seq-id [--from-sidecar <path>]` restores affected palaces. Fixes silent drawer-write drops that began after chromadb 1.5.x upgrades on palaces that still had BLOB-typed `max_seq_id` rows at migration time.
- Set `hnsw:space=cosine` metadata on all collection creation sites — fixes broken similarity scoring under ChromaDB's default L2 distance (#807, #218)
- File-level locking prevents duplicate drawers when agents mine the same file concurrently (#784, #826)
- Hybrid closet+drawer retrieval — closets boost ranking, never gate results (#795)
