Architecture (State 003 Containerized Compose Runtime)

State 003 preserves state 002 routing semantics while moving runtime to Docker Compose and NGINX ingress.

• Inherits architectural baseline from: 002-edge-proxy-uncontainerized
• Generated from: system/architecture.model.json
• Canonical flows: ../001-baseline-uncontainerized-parity/system/end-to-end-flows.md

Entry Points

• ingress: http://localhost:8080
• angular-debug: http://localhost:18093
