🎯 Session Objectives (Completed)​

  1. ✅ Resume from last session context
  2. ✅ Analyze existing V4 deployment (coditect.ai)
  3. ✅ Create V5 migration plan reusing serena infrastructure
  4. ✅ Plan V4/theia frontend integration
  5. ✅ Identify critical infrastructure blockers

📦 Deliverables Created​

1. V4 Integration Analysis​

File: docs/v4-analysis/V4-IMPORTS-AND-INTEGRATION-analysis.md Commit: 5601dae

Content:

  • Complete dependency analysis of v4 Rust/Node.js components
  • CODI2 binary build requirements and integration tasks
  • Authentication flow from v4 API to theia
  • GKE pod auto-provisioning architecture
  • Session management and FoundationDB schema

Key Insight: V4 has proven patterns for FDB multi-tenancy, auth, and pod provisioning that can be directly ported to V5.

2. V5 Migration Plan (Serena Reuse)​

File: docs/v4-analysis/v5-migration-plan-serena-reuse.md Commit: c1d8f7c

Content:

  • 6-phase migration strategy leveraging existing GKE/FDB infrastructure

  • Phase 2: CODI2 binary integration with FDB (Week 2-3)
  • Phase 3: V4 auth migration to theia (Week 3-4)
  • Phase 4: Pod auto-provisioning from v4 Kubernetes (Week 4-5)
  • Phase 5: Session management with FDB persistence (Week 5-6)
  • Phase 6: Zero-downtime blue-green deployment (Week 6)

Infrastructure Confirmed:

  • ✅ GKE cluster: codi-poc-e2-cluster (us-central1-a)
  • ✅ FoundationDB: 3-node StatefulSet at 10.128.0.8:4500
  • ✅ Domain: coditect.ai (34.8.51.57, SSL active)
  • ✅ Container Registry: gcr.io/serene-voltage-464305-n2
  • ✅ CI/CD: Cloud Build pipelines ready

Timeline: 6-8 weeks to V5 MVP with zero downtime migration

3. V4/theia Frontend Integration​

File: docs/v4-analysis/v4-theia-frontend-integration.md Commit: 54154c9

Content:

  • Wrapper architecture (V4 Header/Footer around theia)
  • Theme unification (Chakra UI + theia CSS synchronization)
  • Component integration strategy:
    • llm chat panel → theia sidebar widget
    • Model selector → theia statusbar
    • Workflow mode → theia toolbar
  • Docker persistence (gcloud SDK, kubectl, Rust toolchain)
  • 5-phase implementation plan (3 weeks)

Key Components:

  • theia-embed.tsx - Iframe wrapper for theia
  • side-panel.tsx - V4 sidebar with sessions/projects/models
  • use-theia-theme.ts - Theme sync between Chakra and theia
  • Updated Dockerfile - Persistent gcloud SDK and tools

4. Current Deployment Status​

File: docs/v4-analysis/current-deployment-status.md Commit: 54154c9

Content:

  • Live production analysis of coditect.ai
  • V4 React frontend operational (nginx/1.29.1)
  • Rust API operational (JWT auth required)
  • FoundationDB cluster active (double redundancy, 150GB storage)
  • 50+ documentation pages deployed
  • SSL certificates working (Google-managed)

Deployed Endpoints:

Missing for V5:

  • ❌ theia IDE not deployed
  • ❌ CODI2 not deployed to user pods
  • ❌ User workspace pods not auto-provisioned
  • ❌ WebSocket gateway not deployed
  • ❌ Multi-session support not integrated

5. Critical Infrastructure Roadmap​

File: docs/critical-infrastructure-roadmap.md Commit: b1592f2

Content:

  • Critical Issue #1: WebSocket pod OS connection (sidecar pattern solution)
  • Critical Issue #2: JWT authorization + FDB session integration
  • Critical Issue #3: Coditect server + Knowledge Base as a Service

Solutions:

  1. WebSocket Sidecar:

    • Deploy WebSocket gateway as sidecar container in workspace pods
    • Communicate via localhost (127.0.0.1) - no inter-pod networking
    • Eliminates OS-level networking issues

  2. JWT + FDB Integration:

    • JWT middleware validates token AND looks up session in FDB
    • Session expiration enforced
    • last_access_at updated on each request
    • Cleanup CronJob for expired sessions

  3. Coditect Server + KBaaS:

    • Centralized knowledge management
    • Vertex AI embeddings for RAG
    • Agent coordination registry
    • Cloud Storage backup (gs://serene-voltage-464305-n2-knowledge)

Timeline: 3 weeks to resolve all critical issues

6. Optimal Execution Order​

File: docs/optimal-execution-order.md Commit: b1592f2

Content:

  • Complete dependency graph analysis
  • 7 phases with hard dependencies mapped
  • Parallel execution opportunities identified
  • 3 execution options:
    • 2-person team: 10 days
    • 4-person team: 6 days
    • Solo developer: 15-20 days

Critical Path (7-9 days minimum):

Phase 0: Pre-requisites (Day 1)
    ↓
Phase 1: Auth + Sessions (Day 1-2)
    ↓
Phase 3: Pod Provisioning (Day 3-4)
    ↓
Phase 4: theia Integration (Day 4-6)
    ↓
Phase 6: Testing (Day 7-8)
    ↓
Phase 7: Deployment (Day 8-10)

Key Insight: Phase 1 (Auth + Sessions) is the bottleneck - everything depends on it. Focus resources there first.

Parallel Work:

  • Phase 2 (WebSocket) can run parallel with Phase 1
  • Phase 4.1-4.2 (theia base build) can start immediately
  • Phase 5 (Knowledge Base) can run parallel with Phase 4

🔑 Key Decisions Made​

1. Infrastructure Reuse ✅​

Decision: Use existing serene-voltage-464305-n2 infrastructure Rationale:

  • GKE cluster already configured and operational
  • FoundationDB cluster working with multi-tenant schema
  • SSL certificates active on coditect.ai
  • Container registry and CI/CD pipelines ready
  • Saves 2-4 weeks of infrastructure setup

2. WebSocket Sidecar Pattern ✅​

Decision: Deploy WebSocket gateway as sidecar, not separate pods Rationale:

  • Eliminates inter-pod networking issues
  • Simplifies deployment (localhost communication)
  • More reliable than service mesh
  • Faster to implement (1-2 days vs. 1 week)

3. JWT + FDB Session Validation ✅​

Decision: Validate JWT AND lookup session in FDB on every request Rationale:

  • Prevents token replay attacks
  • Enforces session expiration
  • Tracks last access time
  • Enables session termination (logout from all devices)

4. V4 Wrapper Around theia ✅​

Decision: Keep V4 Header/Footer, embed theia as iframe/component Rationale:

  • Preserves existing docs/auth/theme
  • Reuses 50+ documentation pages
  • Maintains brand consistency
  • Faster than rebuilding UI in theia

5. Phased Deployment (Blue-Green) ✅​

Decision: Deploy V5 alongside V4, gradual traffic migration (10%→50%→100%) Rationale:

  • Zero downtime
  • Ability to rollback if issues
  • Monitor metrics at each stage
  • Reduces risk for production users
