   - Context-aware reasoning messages

DATABASE CHANGES:
- Added 4 new tables: muscle_group_recovery, workout_swaps, custom_workouts, custom_workout_exercises
- Extended workout_logs with: swapped_from_id, source_type, custom_workout_id, custom_workout_exercise_id
- Created 7 new indexes for performance

IMPLEMENTATION:
- Recovery service with 4 core functions
- 2 new route handlers (recovery, smartRecommendations)
- Updated workouts router with swap endpoints
- Integrated recovery tracking into POST /api/logs
- Full error handling and logging

TESTING:

Production Readiness Review — Phase 10-07, Task 5

Date: 2026-03-06
Status: IN PROGRESS
Owner: Architect / PM Autonomy
Target: Production launch sign-off

1. Security Review ✅ AUDITED

1.1 Secrets Management

Current State (Staging):

  • ✅ Template pattern (secrets-template.yaml) — safe to commit, never commit real values
  • ✅ Multiple deployment options documented:
    • Option A: Direct apply (dev/staging only)
    • Option B: Sealed Secrets (kubeseal recommended)
    • Option C: External Secrets Operator (production best practice)

Production Requirements (Sign-Off Gate):

  • MANDATORY: Use sealed-secrets OR External Secrets Operator (Vault/AWS Secrets Manager)
    • ❌ Direct secrets YAML not allowed in production
    • Recommendation: AWS Secrets Manager + External Secrets Operator (if AWS) OR Vault
  • JWT_SECRET generation verified (64-char hex minimum)
    • Example: openssl rand -hex 64
    • Rotation policy: Every 90 days
  • Database credentials use strong passwords (min 32 chars, random)
  • TLS private keys protected (encrypted at rest, RBAC restricted)
  • No hardcoded secrets in container images (scan before push)
  • Secrets rotation procedure documented

Status: ⏳ Awaiting implementation — recommend kubeseal integration pre-production

1.2 RBAC (Role-Based Access Control)

Current State (Staging):

  • ✅ Least-privilege design implemented
    • ServiceAccount: gravl-deployer (no cluster-admin)
    • Role: gravl-staging-deployer (scoped to gravl-staging namespace)
    • Permissions: Specific resources (deployments, services, configmaps, ingress)
    • ✅ Secrets: READ-ONLY (no create/delete)
  • ✅ ClusterRole for read-only cluster access (namespaces, nodes, storageclasses)
  • ✅ No wildcard permissions ("*") — explicit resource lists
  • ✅ No escalation paths (verb: "create" on rolebindings denied)

Production Sign-Off:

  • Principle of least privilege verified
  • No cluster-admin role binding found
  • Secrets operations restricted (no create/delete/patch)
  • Cross-namespace access explicitly allowed only for monitoring (ingress-nginx)
  • Additional: Review production-specific accounts (backup operator, logging sidecar)
    • Add LimitRange to prevent resource exhaustion
    • Add PodSecurityPolicy / Pod Security Standards enforcement

Status: ✅ APPROVED — RBAC baseline acceptable for production

1.3 Network Policies

Current State (Staging):

  • ✅ Default deny ingress (allowlist pattern)
  • ✅ Explicit rules for:
    • ingress-nginx → backend (port 3000)
    • ingress-nginx → frontend (port 80)
    • backend → postgres (port 5432)
    • gravl-monitoring scraping (port 3001 metrics)
  • ✅ Namespace-based pod selection (ingress-nginx selector)

Production Sign-Off:

  • Default deny verified
  • All inter-pod communication explicitly allowed
  • Monitoring namespace access restricted to scrape ports only
  • Additional rules needed:
    • Egress policies (if restrictive DNS/external access required)
    • DNS (CoreDNS access) — currently implicit, should be explicit
    • Logs egress (if using external log aggregation)
    • Recommendation: Add explicit egress for DNS (port 53 UDP/TCP)

Status: ⏳ CONDITIONAL — Needs DNS egress rule before production

1.4 Encryption & TLS

Current State:

  • ✅ TLS secret template provided (staging-tls)
  • ✅ Two options documented:
    • Self-signed for testing (90 days)
    • cert-manager with auto-renewal (recommended)
  • ❌ CRITICAL: TLS certificate generation NOT DOCUMENTED FOR PRODUCTION

Production Sign-Off:

  • MANDATORY: cert-manager installed on production cluster
    • ClusterIssuer configured (Let's Encrypt or internal CA)
    • Ingress annotated with cert-manager issuer
  • TLS enforced (HTTP → HTTPS redirect)
  • Ingress TLS termination verified

Status: ❌ NOT READY — Requires cert-manager setup pre-launch

2. Production Deployment Checklist

Item Status Notes
Staging deployment complete ✅ YES Prometheus, Grafana, AlertManager operational
All services healthy (0 restarts) ✅ YES Monitored via Prometheus
Database migrations validated ⏳ PENDING Verify on production cluster
DNS/ingress configured for prod ⏳ PENDING Staging: staging.gravl.app — Prod: ???
TLS certificate strategy ❌ NOT SETUP Action item: Install cert-manager
Backup procedure tested ❌ BLOCKED StorageClass missing (Task 4 blocker)
Secrets sealed ⏳ PENDING Awaiting sealed-secrets OR External Secrets
Network policies in place ⏳ PENDING Add DNS egress rule
RBAC reviewed ✅ APPROVED Least privilege verified
Monitoring dashboards ready ✅ YES Grafana dashboards operational
Alerting configured ⏳ PENDING Review production-specific thresholds

3. Critical Path to Production (Ordered by Dependency)

Immediate (Block Launch):

  1. Install cert-manager + create ClusterIssuer (security gate)
  2. Implement sealed-secrets OR External Secrets Operator (security gate)
  3. Add DNS egress NetworkPolicy (operational necessity)
  4. Load test on staging (p95 <200ms verification)

High Priority (Should block): 5. Set up image scanning (ECR/Snyk) 6. Configure production alerting thresholds 7. Create production runbooks

Medium Priority (Launch + 24h): 8. Remediate Loki storage + backup job (Task 4 blockers) 9. Implement secrets rotation automation

4. Security Sign-Off Summary

Approved ✅

  • RBAC: Least privilege, no cluster-admin
  • Network Policies: Default deny with explicit allowlist
  • Secrets template pattern: Safe for committed code

Conditional ⏳

  • Secrets management: Requires sealed-secrets OR External Secrets Operator
  • TLS/Encryption: Requires cert-manager setup

Not Ready ❌

  • Image scanning: Requires ECR/Snyk integration
  • Backup integration: Blocked on StorageClass

5. Recommendation

🚫 DO NOT LAUNCH until critical path items #1-4 are complete.

Estimated Time to Production Ready: 6-8 hours

Next Steps:

  1. Assign critical path tasks to DevOps engineer
  2. Parallel track: Complete load testing
  3. Parallel track: Finalize go-live & rollback procedures
  4. Reconvene for final security sign-off before launch

Document Version: 1.0
Last Updated: 2026-03-06 08:50
Next Review: Before production launch (within 24h)

Addendum: Load Test Configuration & Execution

Load Test Script Location

  • k8s/production/load-test.js (k6 script)

Load Test Execution (Pre-Production)

# Install k6 (if not already installed)
# macOS: brew install k6
# Linux: apt-get install k6
# Or use Docker: docker run --rm -v $(pwd):/scripts grafana/k6:latest run /scripts/load-test.js

# Run load test against staging environment
export GRAVL_API_URL="https://staging.gravl.app"
k6 run k8s/production/load-test.js

# Expected output (PASSING):
# p95 latency: <200ms
# p99 latency: <500ms
# Error rate: <0.1%

Load Test Results (Staging Baseline)

TO BE COMPLETED: Run load test on staging environment before production launch.

Expected throughput: >100 req/s Expected p95 latency: <200ms Expected error rate: <0.1%
