Architecture & Scope

​

What We’re Deploying

RELAY Subsystem (4,278 LOC)
├── EventBus (378 LOC) - Event publish/subscribe
├── RelayRouter (438 LOC) - Event routing orchestration
├── RelayService (403 LOC) - Unified service layer
├── WebSocket Manager (597 LOC) - Real-time connections
├── Session Manager (808 LOC) - Collaborative sessions
└── Tests (80+ tests, 100% pass) - Quality assurance

​

Integration Points

• SIFT: Quality assessment service (routes document edits)
• CAST: Semantic tagging service (routes annotations)
• SPAWN: Metadata extraction (event enrichment)
• STITCH: Content coordination (document sync)

​

Multi-Stage Build Plan

​

Stage 0: Strategic Blueprint (CURRENT)

​

Phase 1: Container & Orchestration (2-3 hours)

• Dockerfile: Multi-stage Go build optimization
• docker-compose.yml: Local development environment
• Kubernetes manifests: Base deployment configuration
• Kustomize overlays: Environment-specific configs (dev, staging, prod)

• Dockerfile (optimized for Go, <100MB final image)
• docker-compose.yml (dev environment)
• k8s/base/ (shared k8s resources)
• k8s/overlays/{dev,staging,production}/ (environment overrides)

​

Phase 2: Observability Stack (2-3 hours)

• Prometheus: Metrics collection from /metrics endpoint
• Grafana: Visualization dashboards
• Jaeger: Distributed tracing
• Loki: Log aggregation
• AlertManager: Alert routing

• monitoring/prometheus-config.yml
• monitoring/grafana-dashboards.json
• monitoring/jaeger-config.yml
• monitoring/loki-config.yml
• monitoring/alert-rules.yml

​

Phase 3: CI/CD Pipeline (1-2 hours)

• GitHub Actions: Build, test, push, deploy workflow
• Build: Compile Go code, run tests
• Test: Integration + performance tests
• Push: Docker image to registry
• Deploy: Kustomize to target environment

• .github/workflows/ci.yml (build & test)
• .github/workflows/cd-staging.yml (staging deploy)
• .github/workflows/cd-production.yml (production deploy)
• .github/workflows/performance-test.yml (SLA validation)

​

Phase 4: Validation & Verification (1 hour)

• Integration tests: 7 tests from TASKSET 7 ✅
• Performance tests: 6 benchmarks from TASKSET 7 ✅
• Failure scenarios: 12 tests from TASKSET 7 ✅
• SLA validation: Automated SLA assertions
• Production checklist: Pre-deployment validation

• tests/production-validation-suite.go (new)
• scripts/pre-deployment-checklist.sh
• TASKSET8_PRODUCTION_READINESS_REPORT.md

​

Implementation Strategy

​

Parallelizable Components

Phase 1: Container & Orchestration (Sequential, foundational)
├── Dockerfile (depends on Go code) [1 hour]
├── docker-compose.yml (depends on Dockerfile) [30 min]
└── Kubernetes manifests (depends on docker-compose) [1.5 hours]

Phase 2: Observability Stack (Parallel with Phase 1)
├── Prometheus config [30 min]
├── Grafana dashboards [45 min]
├── Jaeger config [30 min]
├── Loki config [30 min]
└── AlertManager rules [30 min]

Phase 3: CI/CD Pipeline (Can start after Phase 1)
├── Build workflow [30 min]
├── Test workflow [30 min]
├── Deploy workflows [1 hour]
└── Performance test workflow [30 min]

Phase 4: Validation (After Phase 1-3)
├── Production validation tests [30 min]
├── Pre-deployment checklist [30 min]
└── Report generation [30 min]

​

Efficiency Rationale

1. Container first (Phase 1): Enables everything else
2. Observability parallel (Phase 2): Independent of code
3. CI/CD after container (Phase 3): Builds on Phase 1
4. Validation last (Phase 4): Verifies all previous work

​

Key Deliverables

​

1. Container & Orchestration (Phase 1)

​

EXPOSE 8080 8081
HEALTHCHECK CMD wget --quiet --tries=1 --spider http://localhost:8081/health || exit 1
CMD ["relay-service"]

​

• Strategic plan reviewed
• All 4 phases understood
• Parallelization rationale accepted
• Deliverables scope approved
• Success criteria validated
• Ready to proceed with Stage 1

​

Dependencies & Prerequisites

​

External Dependencies

• Docker runtime (local or CI)
• Kubernetes cluster (target environments)
• Container registry (Docker Hub / ECR / GCR)
• GitHub Actions enabled
• PostgreSQL database (RELAY uses GORM)
• Redis (optional, for caching)

​

Internal Dependencies

• ✅ Docker installed locally

​

Assumed Infrastructure

• Kubernetes 1.24+ (supports HPA v2)
• Container registry credentials configured
• DNS resolution for service names
• Persistent storage for logs/metrics (optional)

​

Risk Assessment & Mitigation

​

High-Risk Items

1. Container Image Size
   • Risk: Image too large (>200MB)
   • Mitigation: Multi-stage build, Alpine base
   • Verification: Image scan confirms <100MB
2. Performance Regression
   • Risk: Production deployment slower than tests
   • Mitigation: Load testing before production
   • Verification: Performance tests in CI/CD
3. Downtime During Rollout
   • Risk: Zero downtime deployment fails
   • Mitigation: Rolling updates with PDB
   • Verification: Canary deployment test

​

Medium-Risk Items

1. Configuration Drift
   • Risk: Overlays not properly layered
   • Mitigation: Kustomize validation in CI/CD
   • Verification: Dry-run before deployment
2. Observability Blind Spots
   • Risk: Metrics/logs incomplete
   • Mitigation: Dashboard validation checklist
   • Verification: Load test with monitoring

2. Phase 2: Set up Prometheus, Grafana, Jaeger, Loki (2-3 hours, parallel)
3. Phase 3: Implement CI/CD workflows (1-2 hours, parallel)
4. Phase 4: Run production validation (1 hour, after Phase 1-3)

​

Post-Deployment

1. Monitor metrics in Grafana for 24 hours
2. Validate alert routing
3. Run load testing in production-like environment
4. Document operational procedures
5. Schedule team training

​

Questions for Approval

1. Container Registry: Where should images be pushed? (Docker Hub/ECR/GCR/Private)
2. Kubernetes Cluster: Which cluster for dev/staging/prod? (EKS/GKE/AKS/Self-hosted)
3. Monitoring Backend: Existing Prometheus/Grafana or new? (Cloud/Self-hosted)
4. CI/CD Platform: GitHub Actions OK or different? (GitLab/Jenkins/CircleCI)
5. Rollout Strategy: Blue-green, canary, or rolling? (Recommend: rolling with canary)
6. Runbook Owner: Who maintains operational documentation?
