+# Phase 04 Plan 01: Monitoring Service Layer and Components Summary
+
+**AdminService extended with typed monitoring API methods plus AlertBanner and AdminMonitoringDashboard React components ready for mounting in App.tsx**
+
+## Performance
+
+- **Duration:** 2 min
+- **Started:** 2026-02-24T21:33:40Z
+- **Completed:** 2026-02-24T21:35:33Z
+- **Tasks:** 2
+- **Files modified:** 3
+
+## Accomplishments
+
+- Extended `adminService.ts` with three new exported TypeScript interfaces (AlertEvent, ServiceHealthEntry, AnalyticsSummary) and four new typed API methods (getHealth, getAnalytics, getAlerts, acknowledgeAlert)
+- Created `AlertBanner` component that filters alerts to active critical types only and renders a red banner with per-alert acknowledge buttons
+- Created `AdminMonitoringDashboard` component with a 1x4 service health card grid (colored status dots) and a 1x5 analytics stat card panel with range selector and refresh button
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Extend adminService with monitoring API methods and types** - `f84a822` (feat)
+2. **Task 2: Create AlertBanner and AdminMonitoringDashboard components** - `b457b9e` (feat)
+
+## Files Created/Modified
+
+- `frontend/src/services/adminService.ts` - Added AlertEvent, ServiceHealthEntry, AnalyticsSummary interfaces and getHealth(), getAnalytics(), getAlerts(), acknowledgeAlert() methods
+- `frontend/src/components/AlertBanner.tsx` - New component rendering red banner for active service_down/service_degraded alerts with X Acknowledge buttons
+- `frontend/src/components/AdminMonitoringDashboard.tsx` - New component with service health grid and processing analytics panel with range selector
+
+## Decisions Made
+
+- AlertBanner renders only `status === 'active'` alerts of type `service_down` or `service_degraded`; `recovery` alerts are filtered out as informational
+- Type casing follows backend API response shapes exactly: AlertEvent is snake_case (raw model), ServiceHealthEntry/AnalyticsSummary are camelCase (backend admin.ts remaps them)
+- AdminMonitoringDashboard is self-contained with no required props, following existing Analytics.tsx pattern
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+
+None.
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+
+- All three files are ready to import in Plan 02 (App.tsx wiring)
+- AlertBanner expects `alerts: AlertEvent[]` and `onAcknowledge: (id: string) => Promise<void>` — parent must manage alert state and provide optimistic acknowledge handler
+- AdminMonitoringDashboard has no required props — drop-in for the monitoring tab
