+## CHIT & Geometry Bus Integration
+
+Archon is a **CHIT-aware form consumer** — it receives CGP packets via Agent Zero's MCP interface and can embed geometry context into prompt/form schemas.
+
+**Integration pattern:**
+- Archon does not connect to NATS geometry subjects directly
+- CGP data flows through Agent Zero MCP → Archon `external_tools` interface
+- Form schemas can reference CGP attribution for contributor-aware prompts
+- `persona_service.py` may consume CGP context for persona calibration
+
+**CGP Schema:** Uses canonical `chit.cgp.v1.0` format. See `pmoves/docs/audit/CHIT_INTEGRATION_STATUS.md`.
+
+**Extend:** Add `agent.graphiti.signed.v1` emission to Archon (currently only BoTZ gateway emits this).
