- Add gRPC health check support to Consul registry
- Services are gRPC-only, not HTTP
- Consul was trying HTTP health checks which failed
- Now uses gRPC health checks via grpc.health.v1.Health service
- Update HealthCheckConfig to support both HTTP and gRPC
- Add GRPC field for gRPC service name
- Add UseGRPC flag to choose health check type
- Default to gRPC for services (use_grpc: true in config)
- Fix service address registration in Docker
- Services now register with Docker service name (e.g., auth-service)
- Allows Consul to reach services via Docker network DNS
- Falls back to localhost for local development
- Update default.yaml to enable gRPC health checks
- Set use_grpc: true
- Set grpc: grpc.health.v1.Health
This fixes services being deregistered from Consul due to failed
HTTP health checks. Services will now pass gRPC health checks.

Refactor core kernel and infrastructure to support true microservices
architecture where services are independently deployable.
Phase 1: Core Kernel Cleanup
- Remove database provider from CoreModule (services create their own)
- Update ProvideHealthRegistry to not depend on database
- Add schema support to database client (NewClientWithSchema)
- Update main entry point to remove database dependency
- Core kernel now provides only: config, logger, error bus, health, metrics, tracer, service registry
Phase 2: Service Registry Implementation
- Create ServiceRegistry interface (pkg/registry/registry.go)
- Implement Consul registry (internal/registry/consul/consul.go)
- Add Consul dependency (github.com/hashicorp/consul/api)
- Add registry configuration to config/default.yaml
- Add ProvideServiceRegistry() to DI container
Phase 3: Service Client Interfaces
- Create service client interfaces:
- pkg/services/auth.go - AuthServiceClient
- pkg/services/identity.go - IdentityServiceClient
- pkg/services/authz.go - AuthzServiceClient
- pkg/services/audit.go - AuditServiceClient
- Create ServiceClientFactory (internal/client/factory.go)
- Create stub gRPC client implementations (internal/client/grpc/)
- Add ProvideServiceClientFactory() to DI container
Phase 4: gRPC Service Definitions
- Create proto files for all core services:
- api/proto/auth.proto
- api/proto/identity.proto
- api/proto/authz.proto
- api/proto/audit.proto
- Add generate-proto target to Makefile
Phase 5: API Gateway Implementation
- Create API Gateway service entry point (cmd/api-gateway/main.go)
- Create Gateway implementation (services/gateway/gateway.go)
- Add gateway configuration to config/default.yaml
- Gateway registers with Consul and routes requests to backend services
All code compiles successfully. Core services (Auth, Identity, Authz, Audit)
will be implemented in Epic 2 using these foundations.
- Verified all acceptance criteria for Stories 1.1-1.6
- Updated Status fields from Pending to Completed
- Marked all acceptance criteria checkboxes as completed
- All stories in Epic 1 are now fully implemented and verified
- Add fx.Invoke in main.go to force database and HTTP server creation
- This ensures all providers execute and their lifecycle hooks are registered
- Clean up debug logging statements
- Database migrations and HTTP server now start correctly on application startup
Fixes issue where database migrations and HTTP server were not starting
because FX providers were not being executed (lazy evaluation).
Fixes:
- Added database connection logging with masked DSN
- Added migration progress logging
- Added HTTP server startup logging with address
- Fixed database provider to accept logger parameter
- Improved error visibility throughout initialization
Documentation:
- Moved Story 1.7 (Service Client Interfaces) to Epic 2 as Story 2.7
- Updated Epic 1 and Epic 2 READMEs
- Updated COMPLETE_TASK_LIST.md
- Updated story metadata (ID, Epic, Dependencies)
These changes will help diagnose startup issues and provide better visibility into what the application is doing.
Story 1.6: OpenTelemetry Distributed Tracing
- Implemented tracer initialization with stdout (dev) and OTLP (prod) exporters
- Added HTTP request instrumentation via Gin middleware
- Integrated trace ID correlation in structured logs
- Added tracing configuration to config files
- Registered tracer provider in DI container
Documentation and Setup:
- Created Docker Compose setup for PostgreSQL database
- Added comprehensive Epic 1 summary with verification instructions
- Added Epic 0 summary with verification instructions
- Linked summaries in documentation index and epic READMEs

- Created ErrorPublisher interface
- Added error bus provider with lifecycle management
Story 1.5: HTTP Server Foundation
