# 30 Oct 2025 — Governance rules anchor consolidated

**What changed**

- Published `docs/devops/contracts-and-rules.md` capturing the Sprint 33 governance rules:
  1. API Gateway remains a proxy; Policy Engine composes overlays/simulations.
  2. AOC ingestion persists upstream truth only (no merge/deduplicate logic).
  3. Graph platform standardised on Graph Indexer + Graph API (Cartographer retired).
- Updated backlog hygiene note (`docs/backlog/2025-10-cleanup.md`) and archived the Cartographer handshake plan to point at the new graph platform.
- Logged the rules in `ops/devops/TASKS.md` and `docs/implplan/SPRINTS.md`, removing duplicate references to Cartographer as an active service.

**Reviewers / acknowledgements**

- Platform Leads (DevOps + Graph) confirmed the retirement of Cartographer in favour of Graph Indexer + Graph API.
- Policy Engine Guild acknowledged the proxy-only Gateway posture and downstream overlay ownership.
