# DevOps Governance Rules Anchor (Sprint 33)
 | 
						||
 | 
						||
> **Scope** · Exit deliverable for `DEVOPS-RULES-33-001`  
 | 
						||
> **Audience** · DevOps Guild, Platform leads, service owners  
 | 
						||
> **Related** · `ops/devops/TASKS.md`, `docs/backlog/2025-10-cleanup.md`, `docs/modules/platform/architecture-overview.md`
 | 
						||
 | 
						||
This note consolidates the platform governance rules ratified on 30 October 2025.  
 | 
						||
Each rule captures intent, affected surfaces, enforcement actions, and references to the
 | 
						||
source-of-truth backlogs so that subsequent sprints do not re‑introduce conflicting work.
 | 
						||
 | 
						||
| Rule | Intent & Rationale | Enforcement & Ownership | Follow-ups |
 | 
						||
|------|--------------------|-------------------------|------------|
 | 
						||
| **Gateway is a proxy only; Policy Engine owns overlays/simulations.** | Keep Gateway thin and deterministic: it authenticates, authorises, and forwards requests. All overlay composition, simulation, and policy evaluation stays inside Policy Engine so we avoid duplicated logic and time-of-check drift. | *Owners:* BE‑Base Platform Guild + Policy Engine Guild. <br/>*Enforcement:* Gateway PR reviews block embedded overlay code, new endpoints require `Policy Engine` contracts, CI parity checks compare Gateway ↔ Policy overlay schemas. | - Update open tasks referencing “gateway overlay” work to point at `POLICY-ENGINE-20-00x`.<br/>- Close or rewrite backlog items `WEB-POLICY-20-00x` that attempted to compute overlays in Gateway. |
 | 
						||
| **AOC ingestion is canonical-only; no merges at ingest.** | Concelier/Excititor persist upstream truth plus provenance. Derived severity, merges, or dedupe belong to downstream Policy workflows. This keeps ingestion auditable and replayable. | *Owners:* Concelier & Excititor guilds, DevOps Guild for CI pipelines. <br/>*Enforcement:* `StellaOps.Aoc` guard library, Mongo validators, Roslyn analyzer backlog (`WEB-AOC-19-003`), CI job `stella aoc verify`. | - Ensure ingestion tasks reference the guard library (`StellaOps.Aoc`).<br/>- Retire legacy tasks that still mention merge-at-ingest (see backlog cleanup note). |
 | 
						||
| **Single graph platform: Graph Indexer + Graph API (Cartographer retired).** | Replace the historical Cartographer service with the Graph Indexer + Graph API pairing so graph storage, overlays, and explorer flows share one platform. | *Owners:* Graph Platform Guild, Scheduler Guild, DevOps Guild. <br/>*Enforcement:* New graph work lands in `docs/modules/graph/**` and `src/Graph/**`. Gateway/UI/CLI tickets reference the Graph API endpoints only. | - Archive Cartographer handshake docs and mark Cartographer backlog items as historical.<br/>- Update Scheduler/SBOM/Console tickets to depend on `GRAPH-*` IDs instead of `CARTO-*`. |
 | 
						||
 | 
						||
## Tracking & documentation
 | 
						||
 | 
						||
- ✅ Rules recorded in `docs/implplan/SPRINTS.md` (Sprint 33) and `ops/devops/TASKS.md`.
 | 
						||
- ✅ Repository-wide references to “Cartographer as active platform” updated (see backlog note amendment and doc banner).
 | 
						||
- ✅ Changelog entry (`docs/updates/2025-10-30-devops-governance.md`) captures reviewer acknowledgement.
 | 
						||
 | 
						||
Future adjustments to these rules must update this file and reference `DEVOPS-RULES-33-001`
 | 
						||
when proposing changes so the DevOps Guild can track history.
