Live C1 (live smoke) ~5 tests (opt-in, nightly) Live

Coverage Gaps & Recommendations

Current Gaps

  1. Performance Testing: Only Scanner has PERF model

    • Recommendation: Add PERF to Policy (policy evaluation latency), Concelier (merge performance), Scheduler (scheduling overhead)

  2. Transport Testing: Only Router/Messaging has T1 model

    • Recommendation: Scanner has T1 in TEST_CATALOG.yml but should validate Valkey transport for job queues

  3. Live Connector Tests: Only 5 modules have C1 live smoke tests (opt-in)

    • Recommendation: Run weekly, not nightly; treat as early warning system for schema drift

Recommended Additions (Future Sprints)

Module Missing Model Justification Priority
Policy PERF Policy evaluation latency critical for real-time decisioning HIGH
Concelier PERF Merge performance affects ingestion throughput MEDIUM
Scheduler PERF Scheduling overhead affects job execution latency MEDIUM
Scanner T1 (validate) Job queue transport (Valkey) should have compliance tests HIGH
Authority S1 Token storage/revocation should have migration tests MEDIUM
