## QA Verification Plan

After each wave completes:
1. Docker Compose rebuild: `docker-compose down && docker-compose up --build -d`
2. Health check all services: `curl http://localhost:{port}/health/live`
3. Run E2E tests: verify 38/41+ pass rate maintained
4. Security scan: verify hardcoded credentials removed
5. K8s dry-run: `kubectl apply --dry-run=server -f deployments/staging/kubernetes/`

---

## Success Criteria

- **Wave 1**: All 9 P0 blockers resolved, zero hardcoded credentials in git
- **Wave 2**: All 22 P1 items resolved, CI pipelines for all services
- **Wave 3**: Architecture improvements in place, test coverage >50%
- **Overall**: Project health score from 6.5/10 to 8.5/10
