SOURCE PRECEDENCE

What wins when records disagree

  1. Owner RED / HOLD decisionsExplicit authority and scope constraints
  2. Live GitHubMainline, PR heads, diffs, reviews, migrations and exact-head CI
  3. Canonical program controlMaster Plan and A–F Expanded Execution Pack
  4. Architecture and current reportsMandates, workstreams and final evidence reports
COLLISION CONTROL

Execution rules

One concern per PROne semantic owner and one evidence chain

Mainline owns migration indexThe later branch refreshes and yields

REUSE → EXTEND → ADAPT → CREATENo parallel importer or duplicate contract

Exact reviewed head onlySuperseded and swallowed runs do not count

ARCHITECTURE INTEGRITY

Five-layer assurance spine

01Platform & Trust

Identity, tenant isolation, audit, migrations and operations.

02Intelligence & Integration

AI, RAG, MCP, providers, connectors and event boundaries.

03Shared Assurance

Catalog, controls, evidence, assessments and risk semantics.

04Business Domains

Privacy, regulatory change, AI governance and adoption.

05Continuous Assurance

Drift, findings, actions, reassessment and executive evidence.

Boundary contract Vendor Console and Client Space remain separate, as do Vendor AI and Client AI, Global Catalog RAG and Tenant RAG, Vendor MCP and Client MCP.
