Transform all documentation from modular monolith to true microservices
architecture where core services are independently deployable.
Key Changes:
- Core Kernel: Infrastructure only (no business logic)
- Core Services: Auth, Identity, Authz, Audit as separate microservices
- Each service has own entry point (cmd/{service}/)
- Each service has own gRPC server and database schema
- Services register with Consul for service discovery
- API Gateway: Moved from Epic 8 to Epic 1 as core infrastructure
- Single entry point for all external traffic
- Handles routing, JWT validation, rate limiting, CORS
- Service Discovery: Consul as primary mechanism (ADR-0033)
- Database Pattern: Per-service connections with schema isolation
Documentation Updates:
- Updated all 9 architecture documents
- Updated 4 ADRs and created 2 new ADRs (API Gateway, Service Discovery)
- Rewrote Epic 1: Core Kernel & Infrastructure (infrastructure only)
- Rewrote Epic 2: Core Services (Auth, Identity, Authz, Audit as services)
- Updated Epic 3-8 stories for service architecture
- Updated plan.md, playbook.md, requirements.md, index.md
- Updated all epic READMEs and story files
New ADRs:
- ADR-0032: API Gateway Strategy
- ADR-0033: Service Discovery Implementation (Consul)
New Stories:
- Epic 1.7: Service Client Interfaces
- Epic 1.8: API Gateway Implementation
Epic 7: Testing, Documentation & CI/CD
Overview
Comprehensive test coverage (unit, integration, contract) for all services, complete documentation, production-ready CI/CD pipeline for multiple services, Docker images and deployment guides for each service, and developer tooling.
Note: Testing strategy covers unit tests per service, integration tests across services, and contract tests for service APIs.
