### Learnings
- Services should follow ProjectManagementService pattern: plain constructor injection with factory parameter
- Direct `factory.graphql()` calls appropriate for complex GraphQL mutations not exposed via repositories
- Test mocking simpler without DI container setup
- Leaf services (SubIssue, Milestone) can be extracted in parallel with no inter-dependencies
- useFactory pattern needed for services without @injectable decorator
- reflect-metadata required for tsyringe DI to work properly
- For unit tests: create mock factory with graphql method BEFORE service instantiation
- For mocked classes: pass mockService directly instead of calling `new MockedClass()`
- MCP SDK 1.25+ has "Type instantiation is excessively deep" errors with complex schemas
- Use type assertion `(server.setRequestHandler as any)` with explicit CallToolRequest/CallToolResult types
- CallToolResult format: `{ content: [{ type: 'text', text: string }], structuredContent?: {...} }`
- Zod exports class constructors that work with instanceof (ZodOptional, ZodString, etc.)
- Helper type guards improve readability and enable proper type narrowing without `as any`
- MockPRD interface allows tools to create typed mock objects without full PRDDocument
- Union types (BaseType | ExtendedType) provide flexibility when a function can accept either
- Type guards that narrow types also serve as runtime validators for external input
- E2E tests need credential guards to skip gracefully when credentials are missing
- createTestSuite must always register tests (skip inside) to avoid "no tests" Jest error
- AI service mocking: mock factory BEFORE service instantiation; mock 'ai' package's generateObject
- Fallback path testing is more deterministic than AI path testing (no mock response shaping needed)
- For 100% branch coverage, test edge cases like missing IDs, non-Error thrown objects
- Validation tests: ensure test data has keyword overlap with task for relevance validation to pass
- Completeness score: all 4 optional fields needed for 100% (including dependencyContext)
- jest.resetAllMocks() needed in addition to clearAllMocks() for proper test isolation
- Fallback behavior testing: verify fallback provides useful defaults, not null returns
- CircuitBreakerService: wrap Cockatiel with state tracking and stderr logging
- CorrelationContext: startTrace() wraps operations with correlation ID propagation
- CachePersistence: JSON file persistence with atomic writes and expired entry filtering
- AIResiliencePolicy: composes fallback, retry, circuit breaker, timeout with Cockatiel
- TracingLogger: ILogger with correlationId in every JSON log entry
- ResourceCache persistence: opt-in with enablePersistence(), periodic saves every 5 minutes
- HealthService: aggregates GitHub/AI/cache health into overall status (healthy/degraded/unhealthy)
- health_check MCP tool: returns structured HealthStatus with readOnly annotation
- AIServiceFactory resilience: opt-in via enableResilience(), executeWithResilience() wraps AI calls
- Infrastructure test location: tests/infrastructure/{domain}/ for resilience, observability, cache, health
- TypeScript mock typing: Use `c[0] as string` cast when mapping mock call arrays to avoid type errors
- graphqlWithFeatures enables preview header injection for sub-issues API
- resolveIssueNodeId helper converts issue numbers to node IDs for GraphQL mutations
- Sub-issues require 'sub_issues' feature flag in GraphQL-Features header
- Status updates use 5-value enum: ON_TRACK, AT_RISK, OFF_TRACK, COMPLETE, INACTIVE
- Status update tools follow AI task pattern: standalone executors creating their own factory
- Status update output schemas use nullable() for optional status field
- Sub-issue tools resolve issue numbers to node IDs internally in executors
- Parallel Promise.all for resolving multiple issue numbers (e.g., parent + sub-issue)
- State normalization: OPEN/CLOSED to open/closed in MCP output
- Template schemas: 4 input (mark/unmark/copy/list) + 4 output (project/copied/listItem/list) schemas
- Linking schemas: 6 input (link/unlink repo/team + list repo/team) + 6 output schemas
- Schema pattern: PageInfo schema reusable for all paginated responses
- Tool tests follow pattern: Input Schemas, Tool Definitions, Executors in 3 describe blocks
- Mock GraphQL responses with mockResolvedValue/mockResolvedValueOnce for sequential calls
- Test error handling: missing GITHUB_TOKEN, org/repo/team not found, project not found
- Pagination tests: verify first, after, hasNextPage, endCursor handling
- Phase 8 lifecycle schemas: close/reopen use single ProjectLifecycleOutputSchema
- Draft conversion needs itemId (PVTI_) not content ID, plus repository resolution
- Item position mutation: afterId optional (omit to move to first position)
- Search uses ISSUE_ADVANCED type for AND/OR query support
- Filter tool requires client-side filtering (GitHub API has no server-side filter)
- Project lifecycle tools: close/reopen use same updateProjectV2 mutation with closed boolean
- convertDraftIssueTool needs repository node ID (resolveRepositoryId helper)
- Annotation pattern naming: updateIdempotent not update
