Acceptance

Implementation Result

Implemented stage four of Executor Structured Output V2:

• Added chat_composer prompt and Agent.
• Final answers for PASS, LOW_CONFID, and REJECT now use Composer when Verifier decision is valid.
• Composer input is filtered from Verifier decision and Executor structured output.
• Unsupported, external-unknown, and contradicted claims are excluded from confirmed final-answer material.
• REJECT Composer input has allowed_hypotheses=[].
• Malformed Composer output uses deterministic safe fallback.
• Fallback does not expose raw Composer JSON, raw Executor JSON, or Executor user_facing_answer.
• composer_output is persisted in verifier audit.

Static Verification

• Reviewed implementation diff for stage-four scope.
• cmd /c openspec validate executor-composer-final-answer passed.
• cmd /c openspec validate --specs passed before archive.

Script Verification

Passed:

mvn "-Dtest=ChatServiceSequentialAgentTest" test
mvn "-Dtest=ExecutorGatekeeperServiceTest,VerifierInputHookTest,ChatServiceSequentialAgentTest" test

Coverage:

• Composer prompt loading and invocation.
• valid Composer output as final answer source.
• malformed Composer output fallback.
• PASS no raw Executor JSON leakage.
• LOW_CONFID separation of confirmed material, possible directions, and gaps.
• REJECT safe output without raw Executor answer.
• Gatekeeper and Verifier stage compatibility.

Browser / Manual Verification

Not run. This stage changes backend prompt, routing, parser, audit, and tests only.

Remaining Risks

• Stage five still needs broader eval fixture coverage for full evidence-attribution regressions.
• Composer prompt quality can be improved after real run traces are collected.
• Existing Maven warnings about duplicate test dependency and Lombok builder defaults remain outside this stage.
