## Azure Resources Created
- ACR: socsocacr.azurecr.io (Operation, southeastasia)
- Container App Environment: soc-cae (Operation, southeastasia)
- Container App: soc-langgraph (Operation, southeastasia, port 2024)
  - Scale: 0-2 replicas, 0.5 vCPU / 1GB
  - Registry: socsocacr.azurecr.io (system-assigned managed identity)
- OIDC: oidc-msi-8ac6 granted Contributor on Operation resource group

## What's included
- Full langgraphjs-gen-ui-examples codebase under langgraph/
- Dockerfile: node:20-slim + pnpm, exposes port 2024
- .dockerignore, .gitignore
- GitHub Actions: .github/workflows/deploy-langgraph.yml
  - Trigger: push to main, paths langgraph/**
  - Uses az acr build (cloud build, no local Docker needed)
  - Deploys to soc-langgraph Container App
