What Was Implemented
Phase 1 — Ownership Registry
| Asset | Path |
|---|---|
| Canonical registry | zaixos-engineering-platform/governance/architecture/ownership-registry.json |
| Registry index | zaixos-registry/registry/architecture/governance-index.json |
47 capabilities across PL-003, PL-004, PL-005, PL-006 — validated unique ownership.
Phase 2 — Dependency Rules
| Asset | Path |
|---|---|
| Executable rules | zaixos-engineering-platform/governance/architecture/dependency-rules.json |
| Product scanner | validation/src/Governance/ProductArchitectureScanner.php |
16 forbidden instantiations · 7 forbidden import prefixes · grandfathered PRD-001 legacy orchestrators.
Phase 3 — Architecture Tests
| Suite | Location | Result |
|---|---|---|
| Registry integrity | ZEP ArchitectureGovernanceRegistryTest | 7/7 PASS |
| PL-003 freeze | ArchitectureFreezeComplianceTest | 7/7 PASS |
| PRD-000 governance | ArchitectureGovernanceTest | 5/5 PASS |
| PRD-001 governance | ArchitectureGovernanceTest | 5/5 PASS |
| PL-003 full architecture | 68 tests | 68/68 PASS |
Phase 4 — CI Enforcement
| Repository | Workflow | Governance gate |
|---|---|---|
| ZEP | validate.yml | composer test:governance |
| PL-003 | validate.yml | composer test:governance |
| PRD-000 | validate.yml | test:governance + test:erp |
| PRD-001 | architecture.yml | ArchitectureGovernanceTest blocking |
Phase 5 — ADR Support
| Asset | Path |
|---|---|
| Template | governance/adr/TEMPLATE.md |
| Process | governance/adr/README.md |
| Decision record | docs/platform/adr/ADR-006-enterprise-architecture-governance.md |
Phase 6 — Certification
Auto-generated ownership matrix: docs/GOVERNANCE_CERTIFICATION_REPORT.md (this file).
Ownership Matrix (Summary)
| Platform | Capabilities |
|---|---|
| PL-003 | 14 runtime capabilities |
| PL-004 | 11 intelligence capabilities |
| PL-005 | 7 context/knowledge capabilities |
| PL-006 | 13 observability capabilities |
Products: business capabilities, tools, policies, UI, persistence only.
Violations Detected (Grandfathered — Not New)
| ID | Violation | Status |
|---|---|---|
| G-1 | PRD-001 legacy AI orchestrators (6 classes) | Grandfathered in registry |
| G-2 | PL-003 parallel entry surfaces | Documented; not used by products |
| G-3 | PL-003/PL-005 context overlap | Baseline exception |
| G-4 | PRD-000 observability routes unauthenticated | Not fixed (security gap) |
No new violations introduced by governance implementation.
Remaining Gaps (Honest)
| # | Gap | Priority | Owner |
|---|---|---|---|
| 1 | PL-004/PL-005 lack CI workflows | P1 | Platform repos |
| 2 | Registry validation CI in zaixos-registry | P1 | Registry |
| 3 | PRD-000 observability auth | P0 | PRD-000 |
| 4 | PR template Architecture Impact Report checklist | P2 | All repos |
| 5 | PRD-001 legacy orchestrator removal milestone | P2 | PRD-001 |
| 6 | Scan for new orchestrators outside grandfather list on every PR | P2 | ZEP scanner |
| 7 | OpenTelemetry / distributed tracing | P3 | PL-006 |
Test Execution Log (2026-07-04)
ZEP ArchitectureGovernanceRegistryTest 7/7 PASS
PL-003 Architecture (full) 68/68 PASS
PL-003 ArchitectureFreezeComplianceTest 7/7 PASS
PRD-000 ArchitectureGovernanceTest 5/5 PASS
PRD-001 ArchitectureGovernanceTest 5/5 PASS
PRD-000 EngineeringRuntimePlatform 48/48 PASSConstitutional Rules Now Enforced in CI
- Every capability has exactly one owner (registry test)
- Products must not
new ProviderGateway()/new MemoryRuntime()/ etc. - Products must not import forbidden platform classes outside adapters
- AI module orchestrators must match grandfathered allowlist
- Products must not define
*Runtimeclasses in AI module - PL-003 canonical classes must not duplicate
- Production agent path must use
*AgentOrchestrator→AgentTurnOrchestrator
Governance is now constitutional law. Extend the registry — do not redesign the architecture.
