API Latency Benchmarks
Measures response times for critical API endpoints using pytest-benchmark.
These tests establish baseline performance and enable regression detection through
historical tracking.
Target Metrics:
- Health check <10ms P50 (liveness probe must be instant)
- Agent list <100ms P50 (agent listing)
- Agent get <50ms P50 (single agent fetch)
- Governance check <20ms P50 (cached governance checks)
- Workflow execute <200ms P50 (workflow initiation)
- Canvas create <100ms P50 (canvas creation)
- Episode list <100ms P50 (episode listing)
- Analytics dashboard <500ms P50 (analytics aggregation)
