 3. Preserve current CI gates while adding traceability/maturity checks.
 4. Update the alignment matrix whenever a vision capability changes maturity.

+## Readiness Conditions
+
+- Named maintainers must review and record accept/amend/supersede outcomes for the SAD and ADRs.
+- The adapter safety inventory, maturity consistency audit, and workload baselines remain Iteration 001 work; they are not described as complete controls.
+- Any implementation change follows the test and deployment gates; documentation-only readiness does not waive runtime verification.
