Cross-project: four-graph architecture comparison + collaboration #1
Description
Hey @Grivn 👋
We crossed paths on openclaw/openclaw#13991 (the Associative Hierarchical Memory proposal). Your mnemon architecture caught our attention — the LLM-supervised pattern and four-graph knowledge store are philosophically very close to what we've built.
What We Have
We maintain an OpenClaw fork with a full cognitive memory stack (~150 files, 7 modules). Two of our modules directly overlap with mnemon's approach:
SYNAPSE — multi-model debate with graph-based reasoning (RAAC protocol: Reason, Argue, Arbitrate, Conclude). We use cognitive diversity scoring to decide when debate improves output vs. when it's overhead.
HIPPOCAMPUS — pre-computed concept index (500 anchors, 9500+ chunks). Instead of runtime vector search, we build the graph at consolidation time and retrieve at O(1). Similar to your importance decay + deduplication, but we front-load the computation.
Your four graph types (temporal, entity, semantic, causal) map interestingly to our modules:
| mnemon graph | Our module | Overlap |
|---|---|---|
| Temporal | ENGRAM (episodic timeline) | High — both track event sequences |
| Entity | HIPPOCAMPUS (concept anchors) | Medium — different granularity |
| Semantic | ENGRAM semantic store | High — both vector-based |
| Causal | SYNAPSE (debate chains) | Low — different purpose, potential synergy |
Research Papers
We've written academic papers for each module:
- ENGRAM: Context compaction as cache eviction (paper)
- CORTEX: Persistent agent identity through persona state
- HIPPOCAMPUS: Pre-computed concept indexing for O(1) retrieval
- LIMBIC: Humor detection via bisociation in embedding space
- SYNAPSE: Multi-model deliberation with cognitive diversity
Happy to share full PDFs if you're interested.
Collaboration Ideas
- Benchmark comparison — run both systems on the same long-conversation dataset and compare retrieval quality
- Graph type exchange — your causal graph could improve our SYNAPSE reasoning; our pre-computed index could speed up your recall path
- Joint OpenClaw integration — mnemon as external memory + our fork's cognitive layer = comprehensive agent memory
The fork is at globalcaos/clawdbot-moltbot-openclaw. Would love to exchange notes. 🤝
