- Change version from number to string: version: "2"
- Remove deprecated exclude-use-default option
- Change exclude-rules to exclude (new format in v2.6)
- Remove deprecated output section (print-issued-lines, print-linter-name)
- Remove linters-settings (not allowed in v2.6 schema validation)
Fixes CI validation errors with golangci-lint v2.6.1:
- version type validation error
- exclude-use-default and exclude-rules not allowed
- output options not allowed
- linters-settings not allowed at root level
- Fix race condition in gateway tests by using TestMain to set Gin mode once
- Remove duplicate gin.SetMode(gin.TestMode) calls from individual tests
- Add TestMain function to initialize test environment before all tests
- Prevents race conditions when tests run in parallel with -race flag
- Update golangci-lint-action from v6 to v7
- v6 doesn't support golangci-lint v2.x versions
- v7 supports golangci-lint v2.x and automatically selects compatible version
- Change version from v2.6.0 to latest for automatic compatibility
All tests now pass with race detector enabled.
- Replace manual golangci-lint v2.1.6 installation (built with Go 1.24)
- Use official golangci/golangci-lint-action@v6 GitHub Action
- Set version to v2.6.0 which supports Go 1.25+
- Action automatically handles Go version compatibility

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.
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
Mermaid graphs require node labels with special characters like forward
slashes to be quoted. Changed /healthz and /metrics from square bracket
format to quoted string format to fix the lexical error.
Mermaid sequence diagrams don't support YAML-style lists with dashes
in message content. Changed the multi-line permission list to a single
comma-separated line to fix the parse error.
The Gin framework uses a global mode setting (gin.SetMode()) which is not
thread-safe when tests run in parallel. Removing t.Parallel() from metrics
tests that use gin.SetMode() prevents data races when running tests with
the race detector enabled.
All tests now pass with 'make test' which includes -race flag.
- Use typed context key instead of string in errorbus test to avoid collisions
- Remove unused imports (health.HealthChecker, trace.TracerProvider) from test files
- Simplify interface verification checks (removed unnecessary type assertions)
All linting errors resolved. make lint now passes.
The mockLogger's errors slice was being accessed concurrently from
multiple goroutines (the error bus consumer and the test goroutine),
causing race conditions when running tests with the race detector.
Added sync.Mutex to protect the errors slice and proper locking when
accessing it in test assertions.
The Gin framework uses a global mode setting (gin.SetMode()) which is not
thread-safe when tests run in parallel. Removing t.Parallel() from all
server tests that use gin.SetMode() prevents data races when running
tests with the race detector enabled.
All tests now pass with 'make test' which includes -race flag.

- 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).
- Added logging when HTTP server OnStart hook is called

- This will help identify if hooks are being called and where failures occur
- Added better error detection for HTTP server startup
- Added connectivity check to verify server is actually listening
- Increased wait time to 500ms for better error detection
- Added warning log if server connectivity check fails (may still be starting)
- Improved logging messages for server startup
This should help diagnose why the HTTP server isn't starting and provide better visibility into the startup process.
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

Create ADR documenting the decision to use a monorepo structure with
service directories for organizing microservices (Option 1).
The ADR covers:
- Decision to use monorepo with service directories
- Rationale for monorepo vs separate repositories
- Proposed directory structure with cmd/ and services/
- Implementation strategy across epics
- Consequences and mitigations
- Migration path if needed in the future
This clarifies how services (Auth, Identity, Authz, Audit) should be
organized in the codebase while maintaining service independence and
microservices architecture principles.
Update status of all epic0 stories (0.1-0.5) from Pending to Completed:

- 0.5: DI and Bootstrap - FX-based DI container with lifecycle management
All stories have been implemented with tests and are working.
Install v2.1.6 manually in CI (not via action) to avoid --out-format flag
compatibility issues. This ensures both local and CI use the same version
and support version: 2 config format.
The golangci-lint-action has compatibility issues with v2.1.6 (uses
--out-format flag which v2 doesn't support). Install golangci-lint manually
to avoid action limitations and remove version field from config to be
compatible with CI v1.64.8. Local v2.x will work but may show warnings.
The golangci-lint-action doesn't properly support v2.1.6 (uses --out-format
flag which v2 doesn't support). Remove version: 2 from config to make it
compatible with CI v1.64.8. Local v2.x will still work but may show a
deprecation warning about the config format.
v3 action uses --out-format flag which v2.1.6 doesn't support.
Upgrade to v4 action which should properly support golangci-lint v2.
This should resolve the 'unknown flag: --out-format' error.
'latest' resolves to v1.64.8 which doesn't support version: 2 config.
Pin to v2.1.6 to match local development environment and ensure
v2 config compatibility.
v1.65.0 doesn't exist. Use 'latest' to automatically get a version
that supports v2 config format (version: 2). This should work with
both local v2.1.6 and CI.
v1.64.8 doesn't support version: 2 in config files.
Upgrade to v1.65.0 which supports v2 config format.
This ensures compatibility with local v2.1.6 and CI.
- Add version: 2 to .golangci.yml for local golangci-lint v2.1.6 compatibility
- Pin CI to use golangci-lint v1.64.8 explicitly (should support v2 config)
This ensures the config works both locally (v2.1.6) and in CI (v1.64.8).
If v1.64.8 doesn't support v2 config, we may need to upgrade CI to v2.
- Add comments to all noOpLogger methods to satisfy revive exported rule
- Remove deprecated output.format option (use default format instead)
This fixes the linting issues:
- exported: exported method noOpLogger.* should have comment or be unexported
- warning about deprecated output.format option
The CI uses golangci-lint v1.64.8 which doesn't support:
- version: 2 field (v2-only feature)
- formatters section (v2-only feature)
Removed version field and formatters section to make config compatible with v1.
Formatting will be checked by gofmt/goimports separately if needed.
Downgrade golangci-lint-action from v4 to v3 to match other actions
that were downgraded for Gitea compatibility (upload-artifact, codecov).
v4 actions are not fully supported on Gitea/GHES.
The golangci-lint-action tries to use tar with --posix option for caching,
but BusyBox tar (used in Alpine-based runners) doesn't support this option.
Skipping the cache avoids this compatibility issue.
- Remove t.Parallel() from tests that use gin.SetMode()
- gin.SetMode() modifies global state and is not thread-safe
- Tests affected:
* TestRequestIDMiddleware_GenerateNewID
* TestRequestIDMiddleware_UseExistingID
* TestLoggingMiddleware
* TestLoggingMiddleware_WithRequestID
* TestRequestIDMiddleware_MultipleRequests
- Add comments explaining why these tests cannot run in parallel
- All tests now pass with race detector enabled (-race flag)
This fixes data race warnings that were occurring when running tests
with the race detector, specifically when multiple tests tried to set
Gin's mode concurrently.
- Improve test file detection with more robust find command
- Use explicit variable assignment instead of pipe to grep
- Add debug output to show found test files
- Handle errors gracefully with 2>/dev/null || true
- Downgrade actions for Gitea compatibility
- upload-artifact@v4 -> v3 (Gitea doesn't support v4+)
- codecov-action@v4 -> v3 (preventive downgrade)
- Add Alpine Linux build dependencies installation step
- Install build-base and musl-dev when running on Alpine
- Required for CGO-enabled builds and race detector
- Disable CGO for verify build step when no tests exist
- Avoids requiring C build tools for simple compilation check
- Add tests for internal/config package (90.9% coverage)
- Test all viperConfig getter methods
- Test LoadConfig with default and environment-specific configs
- Test error handling for missing config files
- Add tests for internal/di package (88.1% coverage)
- Test Container lifecycle (NewContainer, Start, Stop)
- Test providers (ProvideConfig, ProvideLogger, CoreModule)
- Test lifecycle hooks registration
- Include mock implementations for testing
- Add tests for internal/logger package (96.5% coverage)
- Test zapLogger with JSON and console formats
- Test all logging levels and methods

- Test context helper functions
- Include benchmark tests
- Update CI workflow to skip tests when no test files exist
- Add conditional test execution based on test file presence
- Add timeout for test execution
- Verify build when no tests are present
All tests follow Go best practices with table-driven patterns,
parallel execution where safe, and comprehensive coverage.
