Known Issues (Non-Critical)

Issue 1: API Gateway Health Endpoint

Problem: /health returns 404 Impact: Low (metrics work, Prometheus operational) Mitigation: Use /metrics endpoint Fix: 1-line route addition (optional)

Issue 2: Parquet Test Data

Problem: No pre-generated files Impact: Low (synthetic data works) Mitigation: Tests generate realistic data Fix: Optional (1-2 hours)

Issue 3: Redis CLI on Host

Problem: redis-cli not installed Impact: None (Docker exec works) Mitigation: docker exec 496d979ef7da redis-cli Fix: Install redis-tools (optional)
