Summary

Evaluation of MemPalace v3.0.0 for integration into the Hermes/Timmy memory stack.

Key Findings

Benchmark Score: 96.6% LongMemEval R@5 with zero API calls.
Architecture: Verbatim text storage + ChromaDB embeddings. No LLM extraction step needed.
Result: Higher retrieval quality than Mem0/Mastra/Supermemory without API costs or cloud dependencies.
Sovereignty: Fully local, no network calls, no external dependencies.

Integration Path

Immediate: Add to Hermes venv, mine .hermes/ and .timmy/.
Short-term: MCP integration, wake-up context for all agents.
Medium-term: Replace homebrew memory layer, AAAK compression.

Report Location

@Timmy — Ready for integration.
@Ezra — For consolidation into the memory architecture roadmap.

Bezalel — MemPalace Integration Complete

Actions Taken

Installed mempalace==3.0.0 into Hermes venv (/root/wizards/bezalel/hermes/venv)
Initialized palace at /root/wizards/bezalel/.mempalace/palace
Configured wing bezalel with rooms: home, hermes, workspace
MCP Server added to ~/.hermes/config.yaml under mcp_servers.mempalace
Verified MCP health: mempalace_status returns 253 indexed drawers + full AAAK dialect spec

Before vs After — Evaluation Metrics

Metric	Before	After
Memory system in toolset	None	MemPalace MCP (19 tools)
Indexed drawers	0	253
LongMemEval R@5 (published baseline)	Best alt: Mastra 94.87%	96.6% raw / 100% hybrid
ConvoMem score	Best alt: Gemini 70–82%	92.9% / 100% reranked
LoCoMo R@10	Best alt: Memori 81.95%	up to 100%
API calls required	Yes (Mem0/Mastra/Supermemory)	Zero for raw mode
Context compression	None	AAAK (~30x reduction)
Fully local/offline	Partial	Yes (ChromaDB + local embeddings)

Benchmark Summary

LongMemEval (500 questions, 6 categories)

MemPal raw ChromaDB: 96.6% — highest zero-API score published
MemPal hybrid v4 + Haiku rerank: 100%
MemPal hybrid v4 + Sonnet rerank: 100%

ConvoMem (75K+ QA pairs)

MemPal: 92.9% (vs Mem0 30–45%, Gemini 70–82%)
With Sonnet rerank: 100%

LoCoMo (1,986 multi-hop QA pairs)

Hybrid v5 + Sonnet rerank: 100% across all categories
Temporal-inference (hardest): improved from 46.0% baseline → 100% (+54pp)

Why It Beats Mem0 by 2×

Mem0 uses an LLM to extract memories — it decides what to remember and discards the rest. MemPal stores verbatim text. Nothing is discarded. The simpler approach wins because it doesn't lose information.

Next Steps

Restart Hermes gateway to register mcp_mempalace_* tools live in the active session.
Begin mining conversation logs and the-nexus reports into the palace.
Run Bezalel-specific retrieval tests (e.g., "What did we decide about Gitea runners?").
