Phase 18: Final Deployment & Monitoring
- CI/CD: ci-build-and-deploy.yml (test→build→scan→push→staging) - CI/CD: ci-canary.yml (canary rollout + auto-rollback) - Observability: Prometheus alerting rules (7 alerts) - Observability: 3 Grafana dashboards (latency, buffers, resources) - Observability: scrape config documentation - Metrics: store metrics collector (src/infra/metrics.ts) - Secrets: docs/deploy/SECRETS.md - Scripts: deploy-local.sh, bench-prod-like.sh - Runbooks: deploy-rollback.md, incident-playbook.md - DR: ops/DR-checklist.md - Security: OCI image signing docs (deploy/oci-signing/) - Perf: results-prod-like.json (100msg/s × 60s, 3 symbols) - Report: PHASE_18_FINAL_REPORT.md Verification: tsc clean, 209/209 tests pass, latency KPIs met (median 0.13ms, p95 0.24ms), zero gaps, zero buffer overflow.
