MVP Demo Trace Acceptance

Result

Accepted for implementation scope.

Verification

Static Verification

• Command: mvn -q -DskipTests compile
• Result: passed
• Notes: New trace controller, service, DTO, profile, verifier fallback, and test sources compile with the project.

Script Verification

• Command: mvn -q "-Dtest=DiagnosisTraceServiceTest,ChatServiceSupervisorAgentTest" test
• Result: passed
• Notes: Covers successful trace aggregation, missing-session 404 path via SessionNotFoundException, low-confidence no-retry behavior, method-tool injection, and verifier fallback when Supervisor skips chat_verifier.

OpenSpec Verification

• Command: openspec validate mvp-demo-trace-acceptance --strict
• Result: passed

GitNexus Verification

• Result: skipped by user decision
• Notes: User requested subsequent project flow to bypass GitNexus.

Manual / Runtime Verification

• Steps: Follow mvp/demo/README.md with --spring.profiles.active=mvp-demo.
• Result: passed
• Notes:
  • Session mvp-demo-payment-timeout-20260703-rerun2 completed as SUCCESS.
  • Chat request returned code=200, success=true, and the same sessionId.
  • Chat duration was 96316 ms; persisted session duration was 95028 ms.
  • Trace API returned code=200, returnedSteps=13, returnedTools=12, hasVerifier=true, and verifierVerdict=LOW_CONFID.
  • Trace agents included planner,executor,verifier.
  • Trace tools included lookup_knowledge,query_logs,query_metrics.
  • Feedback submission returned success, and a follow-up trace query showed feedback=useful.
  • MySQL verification confirmed agent_step count 13 with agents executor,planner,verifier.
  • MySQL verification confirmed tool_invocation count 12 with tools lookup_knowledge,query_logs,query_metrics.

Completed Scope

• Added GET /api/diagnosis/{sessionId}/trace.
• Added read-only trace aggregation from persisted diagnosis tables.
• Added mvp-demo profile overlay.
• Added payment-timeout demo acceptance documentation.
• Added MVP note for interview storytelling.
• Added verifier fallback so runtime trace remains complete when Supervisor returns without verifier_output.

Known Limits

• mvp-demo is not a fully offline mock runtime.
• Runtime still depends on available MySQL, Redis, Milvus/Zilliz, model, and embedding configuration.
• Sensitive configuration cleanup remains intentionally deferred.
• Supervisor can still make inefficient routing choices inside a single round; ChatService now invokes chat_verifier as a fallback when Supervisor returns without verifier_output, so trace completeness is preserved for the MVP demo.

Handoff

• Runtime demo passed with current infrastructure.
• OpenSpec archive confirmation: requested by user after successful rerun.
