Jason Woltje 5d348526de feat(#71): implement graph data API
Implemented three new API endpoints for knowledge graph visualization:

1. GET /api/knowledge/graph - Full knowledge graph
   - Returns all entries and links with optional filtering
   - Supports filtering by tags, status, and node count limit
   - Includes orphan detection (entries with no links)

2. GET /api/knowledge/graph/stats - Graph statistics
   - Total entries and links counts
   - Orphan entries detection
   - Average links per entry
   - Top 10 most connected entries
   - Tag distribution across entries

3. GET /api/knowledge/graph/:slug - Entry-centered subgraph
   - Returns graph centered on specific entry
   - Supports depth parameter (1-5) for traversal distance
   - Includes all connected nodes up to specified depth

New Files:
- apps/api/src/knowledge/graph.controller.ts
- apps/api/src/knowledge/graph.controller.spec.ts

Modified Files:
- apps/api/src/knowledge/dto/graph-query.dto.ts (added GraphFilterDto)
- apps/api/src/knowledge/entities/graph.entity.ts (extended with new types)
- apps/api/src/knowledge/services/graph.service.ts (added new methods)
- apps/api/src/knowledge/services/graph.service.spec.ts (added tests)
- apps/api/src/knowledge/knowledge.module.ts (registered controller)
- apps/api/src/knowledge/dto/index.ts (exported new DTOs)
- docs/scratchpads/71-graph-data-api.md (implementation notes)

Test Coverage: 21 tests (all passing)
- 14 service tests including orphan detection, filtering, statistics
- 7 controller tests for all three endpoints

Follows TDD principles with tests written before implementation.
All code quality gates passed (lint, typecheck, tests).

ORCH-110: Git Operations (clone, commit, push)

Objective

Implement git operations service using simple-git library to support agent git workflows.

Acceptance Criteria

  • src/git/git-operations.service.ts implemented
  • Clone repository
  • Create branch
  • Commit changes with message
  • Push to remote
  • Git config (user.name, user.email from environment)
  • NestJS service with proper dependency injection
  • Comprehensive unit tests following TDD principles
  • Mock simple-git for unit tests (no actual git operations)
  • Test coverage >= 85%

Approach

Following TDD (Red-Green-Refactor):

  1. RED: Write failing tests first

    • Test git config setup
    • Test clone repository
    • Test create branch
    • Test commit changes
    • Test push to remote
    • Test error handling
  2. GREEN: Implement minimum code to pass tests

    • Create GitOperationsService with NestJS
    • Implement each git operation
    • Use simple-git library
    • Read config from ConfigService
  3. REFACTOR: Improve code quality

    • Extract common patterns
    • Improve error messages
    • Add type safety

Implementation Notes

Service Interface

class GitOperationsService {
  async cloneRepository(url: string, localPath: string): Promise<void>
  async createBranch(localPath: string, branchName: string): Promise<void>
  async commit(localPath: string, message: string): Promise<void>
  async push(localPath: string, remote?: string, branch?: string): Promise<void>
}

Dependencies

  • simple-git: Git operations
  • @nestjs/config: Configuration
  • ConfigService: Access git config (userName, userEmail)

Testing Strategy

  • Mock simple-git using vitest.fn()
  • No actual git operations in tests
  • Test all success paths
  • Test error handling
  • Verify git config is set
  • Verify correct parameters passed to simple-git

Progress

  • Create test file with failing tests
  • Implement GitOperationsService
  • All tests passing
  • Coverage >= 85%
  • Update git.module.ts
  • Create types file
  • Add index.ts exports

Testing Results

pnpm test src/git/git-operations.service.spec.ts --run
# Test Files  1 passed (1)
#      Tests  14 passed (14)

pnpm test src/git/git-operations.service.spec.ts --coverage --run
# Coverage: 100% statements, 85.71% branches, 100% functions, 100% lines
# Exceeds 85% requirement ✓

pnpm typecheck
# No errors ✓

Notes

  • simple-git already in package.json (v3.27.0)
  • Git config already in orchestrator.config.ts
  • Service uses dependency injection for testability
  • All git operations async
  • Error handling preserves original error messages
