Introduce plugins/memory/mempalace/ — a native MemoryProvider that replaces the MCP bridge with direct Python API calls for lower latency and richer integration. Features: - Semantic search over the palace graph (L0 closets + L1 memories) - Knowledge Graph queries and updates (add/invalidate facts) - Automatic diary journaling at session end (AAAK format) - Turn archiving into the palace via background threads - Background prefetch that pre-warms recall for the next turn - Per-session turn counter with periodic diary checkpoints (every 25 turns) - 5 tools exposed to the model: mempalace_search, mempalace_kg_query, mempalace_kg_add, mempalace_diary_read, mempalace_diary_write - Crash-safe diary writes: flat file always saved first, ChromaDB ingest is best-effort (non-fatal on failure) Built for MemPalace v3.3.4. Backed by ChromaDB + Knowledge Graph.

Thanks for the contribution! Per the updated CONTRIBUTING.md, new memory providers are no longer accepted as in-tree additions to
Closing this in line with that policy. The path forward is to publish it as a standalone plugin so users can install it directly without touching the Hermes source tree. Once it's published, a small docs PR adding it to the Community plugins section of the README is welcome. Sorry for the bump — appreciate the time you put into this. |
