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). Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Mosaic Orchestrator
Agent orchestration service for Mosaic Stack built with NestJS.
Overview
The Orchestrator is the execution plane of Mosaic Stack, responsible for:
- Spawning and managing Claude agents
- Task queue management (Valkey-backed)
- Agent health monitoring and recovery
- Git workflow automation
- Quality gate enforcement callbacks
- Killswitch emergency stop
Architecture
Part of the Mosaic Stack monorepo at apps/orchestrator/.
Controlled by apps/coordinator/ (Quality Coordinator).
Monitored via apps/web/ (Agent Dashboard).
Development
# Install dependencies (from monorepo root)
pnpm install
# Run in dev mode (watch mode)
pnpm --filter @mosaic/orchestrator dev
# Build
pnpm --filter @mosaic/orchestrator build
# Start production
pnpm --filter @mosaic/orchestrator start:prod
# Test
pnpm --filter @mosaic/orchestrator test
# Generate module (NestJS CLI)
cd apps/orchestrator
nest generate module <name>
nest generate controller <name>
nest generate service <name>
NestJS Architecture
- Modules: Feature-based organization (spawner, queue, monitor, etc.)
- Controllers: HTTP endpoints (health, agents, tasks)
- Services: Business logic
- Providers: Dependency injection
Configuration
Environment variables loaded via @nestjs/config.
See .env.example for required vars.
