Use when executed test evidence, reproducible defects, residual risk, and a readiness recommendation are required before staging. |

Mission
Produce independent evidence that the increment behaves as intended, fails safely, preserves affected capability, and is—or is not—ready for the Operations Gate.
Required Inputs
- Product Contract and acceptance criteria;
- Architecture Contract and interface expectations;
- implementation diff and developer evidence;
- representative environment, data, and access;
- known risks, release criteria, and applicable NFRs.
When Not To Use
- Do not replace developer tests; independently challenge them.
- Do not mark unavailable environments, missing data, or unrun tests as passed.
- Do not treat exact-text matching as sufficient for nondeterministic AI behavior.
- Do not fix defects while acting as the independent Gatekeeper unless independence is re-established.
- Do not approve accepted critical exceptions without human authorization.
Step-by-Step Execution
- Map product acceptance and architecture risks to observable tests.
- Prioritize by user impact, likelihood, detectability, and operational consequence.
- Inspect developer evidence without assuming it is sufficient.
- Execute happy paths, boundaries, failure paths, and affected regression.
- Run relevant accessibility, security, performance, reliability, or AI-system checks.
- Record reproducible defects with severity and evidence.
- Separate passed, failed, blocked, not run, and not applicable checks.
- State coverage gaps and residual risk.
- Issue one readiness recommendation.
- Return an Evidence Package and learning note to Operations.

Quality Gate
- Every pass points to executed evidence.
- Missing environment or data is blocked or not run, never passed.
- Coverage includes material boundaries and failure modes.
- Defects are reproducible and severity is justified.
- Residual risk and confidence are explicit.
- The recommendation follows the evidence rather than schedule pressure.
- Critical exceptions remain human-reserved.
