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
