Jason Woltje 12abdfe81d feat(#93): implement agent spawn via federation
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

Issue #67: [KNOW-015] Search UI

Objective

Build a comprehensive search interface in the Next.js web UI with search-as-you-type, filters, keyboard shortcuts, and highlighted snippets.

Approach

  1. Review existing web UI structure and components
  2. Design component architecture for search functionality
  3. Implement TDD workflow (RED-GREEN-REFACTOR):
    • Write tests for search input component
    • Implement search input with Cmd+K shortcut
    • Write tests for search results page
    • Implement search results with highlighting
    • Write tests for filter sidebar
    • Implement filter functionality
    • Add no results state
  4. Ensure all tests pass and coverage meets 85% minimum
  5. Run quality gates and code review
  6. Commit and close issue

Component Architecture

  • SearchInput - Header search component with Cmd+K shortcut
  • SearchResults - Main results page/component
  • SearchResultItem - Individual result with highlighted snippets
  • SearchFilters - Sidebar for tag and status filtering
  • NoResults - Empty state component

Progress

  • Create scratchpad
  • Review existing web UI structure
  • Write tests for SearchInput component
  • Implement SearchInput with keyboard shortcut
  • Write tests for SearchResults page
  • Implement SearchResults page
  • Write tests for SearchResultItem with highlighting
  • Implement result item with snippet highlighting
  • Write tests for SearchFilters
  • Implement filter sidebar
  • Write tests for NoResults state
  • Implement no results state
  • Add debounced search-as-you-type
  • Create search page at /knowledge/search
  • Add search button to Navigation header
  • Fix Input component to support forwardRef
  • All tests passing (100% coverage)
  • Typecheck passing
  • Lint passing
  • Commit changes (3cb6eb7)
  • Close issue #67

Summary

Successfully implemented comprehensive search UI for knowledge base with:

  • Full TDD approach (tests written first)
  • 100% code coverage on main components
  • All acceptance criteria met
  • PDA-friendly design principles followed
  • Quality gates passed (typecheck, lint, tests)

Components created:

  • SearchInput (debounced, Cmd+K shortcut)
  • SearchFilters (tags and status filtering)
  • SearchResults (main results view with highlighting)
  • Search page at /knowledge/search
  • Updated Navigation with search button

All files pass pre-commit hooks and quality checks.

Testing Strategy

  • Unit tests for all components
  • Test keyboard shortcuts (Cmd+K, Escape)
  • Test debouncing behavior
  • Test filter interactions
  • Test safe HTML rendering for highlights
  • Test no results state
  • Aim for 85%+ coverage

Notes

  • Use Shadcn/ui components (Input, Card, Badge, etc.)
  • Follow PDA-friendly language (no "URGENT", "MUST", etc.)
  • Use visual indicators: 🟢 Active, 🔵 Scheduled, ⏸️ Paused, 💤 Dormant, Not started
  • Safely render HTML snippets from API (use dangerouslySetInnerHTML with sanitization or a library)
  • Debounce search input to avoid excessive API calls
  • Cmd+K should open search modal/focus search input
  • Escape should close search modal if open
