Restore three `_pin_hnsw_threads` tests that the previous integrity-gate commit deleted. The function is still live code on develop (defined at chroma.py:207, called from chroma.py:705 + mcp_server.py), so the deletion left the import unused (ruff F401) and dropped coverage on a function unrelated to this PR's scope. Restored verbatim from main. Plus three nits @igorls flagged: - **Thread-safety doc**: `_quarantined_paths` mutation is lock-free; documented that idempotency of `quarantine_stale_hnsw` is the safety property (concurrent same-palace calls produce a benign redundant rename attempt that no-ops, no need for a lock). - **Pickle protocol assumption**: `_segment_appears_healthy` requires PROTO ≥ 2 (`0x80`). Documented; matches what chromadb writes today, and a future protocol-0/1 emission would conservatively quarantine + lazy-rebuild rather than mis-classify as healthy. - Class-level vs module-level scope: keeping class-level — the conftest reset is the controlled case, and module-level wouldn't remove the foot-gun, just relocate it. Conftest reset documented in the existing comment is the right pattern for test isolation. Style nit (`Path(marker).touch()` vs `open(marker, "a").close()`) deferred — that pattern lives in #1177's territory, not #1173's. 37/37 tests pass on the PR branch.

mempalace/ — Core Package
The Python package that powers MemPalace. All modules, all logic.
Modules
| Module | What it does |
|---|---|
cli.py |
CLI entry point — routes to mine, search, init, compress, wake-up |
config.py |
Configuration loading — ~/.mempalace/config.json, env vars, defaults |
normalize.py |
Converts 5 chat formats (Claude Code JSONL, Claude.ai JSON, ChatGPT JSON, Slack JSON, plain text) to standard transcript format |
miner.py |
Project file ingest — scans directories, chunks by paragraph, stores to ChromaDB |
convo_miner.py |
Conversation ingest — chunks by exchange pair (Q+A), detects rooms from content |
searcher.py |
Semantic search via ChromaDB vectors — filters by wing/room, returns verbatim + scores |
layers.py |
4-layer memory stack: L0 (identity), L1 (critical facts), L2 (room recall), L3 (deep search) |
dialect.py |
AAAK compression — entity codes, emotion markers, 30x lossless ratio |
knowledge_graph.py |
Temporal entity-relationship graph — SQLite, time-filtered queries, fact invalidation |
palace_graph.py |
Room-based navigation graph — BFS traversal, tunnel detection across wings |
mcp_server.py |
MCP server — 19 tools, AAAK auto-teach, Palace Protocol, agent diary |
onboarding.py |
Guided first-run setup — asks about people/projects, generates AAAK bootstrap + wing config |
entity_registry.py |
Entity code registry — maps names to AAAK codes, handles ambiguous names |
entity_detector.py |
Auto-detect people and projects from file content |
general_extractor.py |
Classifies text into 5 memory types (decision, preference, milestone, problem, emotional) |
room_detector_local.py |
Maps folders to room names using 70+ patterns — no API |
spellcheck.py |
Name-aware spellcheck — won't "correct" proper nouns in your entity registry |
split_mega_files.py |
Splits concatenated transcript files into per-session files |
Architecture
User → CLI → miner/convo_miner → ChromaDB (palace)
↕
knowledge_graph (SQLite)
↕
User → MCP Server → searcher → results
→ kg_query → entity facts
→ diary → agent journal
The palace (ChromaDB) stores verbatim content. The knowledge graph (SQLite) stores structured relationships. The MCP server exposes both to any AI tool.
