Implements FED-010: Agent Spawn via Federation feature that enables spawning and managing Claude agents on remote federated Mosaic Stack instances via COMMAND message type. Features: - Federation agent command types (spawn, status, kill) - FederationAgentService for handling agent operations - Integration with orchestrator's agent spawner/lifecycle services - API endpoints for spawning, querying status, and killing agents - Full command routing through federation COMMAND infrastructure - Comprehensive test coverage (12/12 tests passing) Architecture: - Hub → Spoke: Spawn agents on remote instances - Command flow: FederationController → FederationAgentService → CommandService → Remote Orchestrator - Response handling: Remote orchestrator returns agent status/results - Security: Connection validation, signature verification Files created: - apps/api/src/federation/types/federation-agent.types.ts - apps/api/src/federation/federation-agent.service.ts - apps/api/src/federation/federation-agent.service.spec.ts Files modified: - apps/api/src/federation/command.service.ts (agent command routing) - apps/api/src/federation/federation.controller.ts (agent endpoints) - apps/api/src/federation/federation.module.ts (service registration) - apps/orchestrator/src/api/agents/agents.controller.ts (status endpoint) - apps/orchestrator/src/api/agents/agents.module.ts (lifecycle integration) Testing: - 12/12 tests passing for FederationAgentService - All command service tests passing - TypeScript compilation successful - Linting passed Refs #93 Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

Issue #72: Graph Visualization Component
Objective
Create interactive knowledge graph visualization component in Next.js web UI using the graph API from issue #71.
Approach
- Research and select graph visualization library
- Follow TDD: Write tests before implementation
- Create graph visualization component with:
- Force-directed layout
- Node sizing based on connections
- PDA-friendly status colors
- Click handlers for navigation
- Zoom/pan controls
- Layout toggle options
- Performance test with 500+ nodes
- Integrate with graph API
Library Selection
Evaluating options:
- react-force-graph: WebGL-based, high performance, good for 500+ nodes
- vis-network: Canvas-based, feature-rich
- d3-force: Low-level, full control but more complex
Decision: react-force-graph-2d
- Best performance for 500+ nodes (WebGL rendering)
- Simple API
- Built-in zoom/pan
- Easy to customize node appearance
- Active maintenance
Progress
- Create scratchpad
- Set up component structure
- Write tests (TDD) - 16 tests, all passing
- Implement basic graph rendering
- Add node sizing logic (based on connection count)
- Add status-based coloring (PDA-friendly colors)
- Implement click handlers (navigation to entry)
- Add layout controls (force, hierarchical, circular)
- Performance testing (supports 500+ nodes)
- Create display page at /knowledge/graph
- Add filters (status, tags, orphans)
- Type checking passes
- Linting passes
- Committed (commit
0e64dc8) - Issue #72 closed
Testing Strategy
- Unit tests for graph component
- Test node rendering
- Test interaction handlers
- Test layout switching
- Performance test with large datasets
PDA-Friendly Colors
From CLAUDE.md:
- 🟢 Active: green-500
- 🔵 Scheduled: blue-500
- ⏸️ Paused: yellow-500
- 💤 Dormant: gray-400
- ⚪ Archived: gray-300
Implementation Summary
Components Created
-
KnowledgeGraphViewer.tsx - Main graph visualization component
- Force-directed, hierarchical, and circular layout options
- PDA-friendly status colors (green=published, blue=draft, gray=archived)
- Node sizing based on connection count
- Interactive zoom/pan controls
- Click to navigate to entry
- Filters: status, tags, orphan visibility
- Legend panel showing color meanings
-
KnowledgeGraphViewer.test.tsx - Comprehensive test suite
- 16 tests covering all features
- 100% test pass rate
- Performance test with 500+ nodes
-
page.tsx - Display page at /knowledge/graph
API Integration
- Added fetchKnowledgeGraph() to knowledge.ts API client
- Fetches from /api/knowledge/graph endpoint (implemented in issue #71)
- Supports filtering by tags, status, and limit
Libraries Used
- @xyflow/react - Graph rendering and layout
- elkjs - Hierarchical layout algorithm
- Already in package.json, no new dependencies needed
Features Implemented
- ✅ Force-directed layout (default)
- ✅ Hierarchical layout (ELK algorithm)
- ✅ Circular layout
- ✅ Node sizing based on connections (40px - 120px)
- ✅ PDA-friendly colors by status
- ✅ Orphan node detection and highlighting
- ✅ Click to navigate to entry
- ✅ Zoom and pan controls (ReactFlow built-in)
- ✅ MiniMap for navigation
- ✅ Filters: status, tags, show/hide orphans
- ✅ Statistics display (total nodes, edges, orphans)
- ✅ Legend panel
- ✅ Performance tested with 500+ nodes
Notes
- Using @xyflow/react instead of react-force-graph (already in dependencies)
- Memoization implemented for filtered nodes/edges
- Layout calculations are async to prevent UI blocking
- All quality gates passed (tests, typecheck, lint)
