feat(#92): implement Aggregated Dashboard View
Implement unified dashboard to display tasks and events from multiple federated Mosaic Stack instances with clear provenance indicators. Backend Integration: - Extended federation API client with query support (sendFederatedQuery) - Added query message fetching functions - Integrated with existing QUERY message type from Phase 3 Components Created: - ProvenanceIndicator: Shows which instance data came from - FederatedTaskCard: Task display with provenance - FederatedEventCard: Event display with provenance - AggregatedDataGrid: Unified grid for multiple data types - Dashboard page at /federation/dashboard Key Features: - Query all ACTIVE federated connections on load - Display aggregated tasks and events in unified view - Clear provenance indicators (instance name badges) - PDA-friendly language throughout (no demanding terms) - Loading states and error handling - Empty state when no connections available Technical Implementation: - Uses POST /api/v1/federation/query to send queries - Queries each connection for tasks.list and events.list - Aggregates responses with provenance metadata - Handles connection failures gracefully - 86 tests passing with >85% coverage - TypeScript strict mode compliant - ESLint compliant PDA-Friendly Design: - "Unable to reach" instead of "Connection failed" - "No data available" instead of "No results" - "Loading data from instances..." instead of "Fetching..." - Calm color palette (soft blues, greens, grays) - Status indicators: 🟢 Active, 📋 No data, ⚠️ Error Files Added: - apps/web/src/lib/api/federation-queries.ts - apps/web/src/lib/api/federation-queries.test.ts - apps/web/src/components/federation/types.ts - apps/web/src/components/federation/ProvenanceIndicator.tsx - apps/web/src/components/federation/ProvenanceIndicator.test.tsx - apps/web/src/components/federation/FederatedTaskCard.tsx - apps/web/src/components/federation/FederatedTaskCard.test.tsx - apps/web/src/components/federation/FederatedEventCard.tsx - apps/web/src/components/federation/FederatedEventCard.test.tsx - apps/web/src/components/federation/AggregatedDataGrid.tsx - apps/web/src/components/federation/AggregatedDataGrid.test.tsx - apps/web/src/app/(authenticated)/federation/dashboard/page.tsx - docs/scratchpads/92-aggregated-dashboard.md Testing: - 86 total tests passing - Unit tests for all components - Integration tests for API client - PDA-friendly language verified - TypeScript type checking passing - ESLint passing Ready for code review and QA testing. Related Issues: - Depends on #85 (FED-005: QUERY Message Type) - COMPLETED - Depends on #91 (FED-008: Connection Manager UI) - COMPLETED - Uses #90 (FED-007: EVENT Subscriptions) infrastructure Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
