## Tooling Note

The required `codebase-retrieval` and LSP tools were not exposed in this session. Impact analysis used `rg`, direct file reads, existing OpenSpec/devflow artifacts, and targeted tests instead.

## Implementation Evidence

- `src/main/java/com/superbiz/agent/service/ChatService.java`
  - Adds `prompt_audit` under `verifier_evaluation` through the shared `persistVerifierEvaluation(...)` path.
  - Uses compact metadata only: audit version, prompt names, prompt versions, and resource paths.
- `src/main/java/com/superbiz/agent/eval/DiagnosisTraceEvaluator.java`
  - Adds deterministic checks for `requirePromptAudit`, `expectedPromptAuditVersion`, `expectedPromptVersions`, and `requireGatekeeperRules`.
- `src/main/java/com/superbiz/agent/eval/DiagnosisEvalReportWriter.java`
  - Adds Prompt Audit and Gatekeeper rule count columns to Markdown reports.
- `mvp/eval/cases/diagnosis-cases.json`
  - Expands fixed baseline to 12 fixture-backed cases.
- `mvp/eval/fixtures/prompt-gatekeeper-audit-closure-pass.json`
  - Positive PASS fixture proving Prompt audit and Gatekeeper rule metadata closure.
- `mvp/eval/fixtures/audit-metadata-low-confid.json`
  - LOW_CONFID fixture proving safe answer behavior while audit metadata remains present.
- `mvp/demo/scripts/run-interview-demo-check.ps1`
  - Adds service readiness, Chat, Trace, feedback, and summary output for interview preflight.

## Verification Evidence

- OpenSpec:
  - `openspec validate interview-demo-quality-audit --strict`: passed before archive.
  - `openspec validate --specs --strict`: 10 specs passed after merging deltas into main specs.
- Unit/eval:
  - `mvn -q "-Dtest=DiagnosisTraceEvaluatorTest" test`: passed.
  - `mvn -q "-Dtest=ChatServiceSequentialAgentTest" test`: passed.
  - `mvn -q "-Dtest=DiagnosisTraceEvaluatorTest,DiagnosisEvalBaselineDiffTest,ChatServiceSequentialAgentTest,ExecutorGatekeeperServiceTest,VerifierInputHookTest" test`: passed.
- Compile:
  - `mvn -q -DskipTests compile`: passed.
- E2E:
  - Started `mvn spring-boot:run -Dspring-boot.run.profiles=mvp-demo`.
  - Ran `mvp/demo/scripts/run-interview-demo-check.ps1` against `http://localhost:9900`.
  - Summary recorded `chatSuccess=true`, `verdict=LOW_CONFID`, `gatekeeperRuleSetVersion=gatekeeper-rules-v1`, and `promptAuditVersion=chat-prompts-v1`.
