Create the three building blocks for Phase 4 frontend: extend adminService with typed monitoring API methods, build the AlertBanner component, and build the AdminMonitoringDashboard component.

Purpose: These components and service methods are the foundation that Plan 02 wires into the Dashboard. Separating creation from wiring keeps each plan focused. Output: Three files ready to be imported and mounted in App.tsx.

@.planning/PROJECT.md @.planning/ROADMAP.md @.planning/STATE.md @.planning/phases/04-frontend/04-RESEARCH.md @frontend/src/services/adminService.ts @frontend/src/components/Analytics.tsx @frontend/src/components/UploadMonitoringDashboard.tsx @frontend/src/utils/cn.ts Task 1: Extend adminService with monitoring API methods and types frontend/src/services/adminService.ts Add three exported interfaces and four new methods to the existing AdminService class in `frontend/src/services/adminService.ts`.

Interfaces to add (above the AdminService class):

export interface AlertEvent {
  id: string;
  service_name: string;
  alert_type: 'service_down' | 'service_degraded' | 'recovery';
  status: 'active' | 'acknowledged' | 'resolved';
  message: string | null;
  details: Record<string, unknown> | null;
  created_at: string;
  acknowledged_at: string | null;
  resolved_at: string | null;
}

export interface ServiceHealthEntry {
  service: string;
  status: 'healthy' | 'degraded' | 'down' | 'unknown';
  checkedAt: string | null;
  latencyMs: number | null;
  errorMessage: string | null;
}

export interface AnalyticsSummary {
  range: string;
  totalUploads: number;
  succeeded: number;
  failed: number;
  successRate: number;
  avgProcessingMs: number | null;
  generatedAt: string;
}

IMPORTANT type casing note (from RESEARCH Pitfall 4):

• ServiceHealthEntry uses camelCase (backend admin.ts remaps to camelCase)
• AlertEvent uses snake_case (backend returns raw model data)
• AnalyticsSummary uses camelCase (from backend analyticsService.ts)

Methods to add inside the AdminService class:

async getHealth(): Promise<ServiceHealthEntry[]> {
  const response = await apiClient.get('/admin/health');
  return response.data.data;
}

async getAnalytics(range: string = '24h'): Promise<AnalyticsSummary> {
  const response = await apiClient.get(`/admin/analytics?range=${range}`);
  return response.data.data;
}

async getAlerts(): Promise<AlertEvent[]> {
  const response = await apiClient.get('/admin/alerts');
  return response.data.data;
}

async acknowledgeAlert(id: string): Promise<AlertEvent> {
  const response = await apiClient.post(`/admin/alerts/${id}/acknowledge`);
  return response.data.data;
}

Keep all existing methods and interfaces. Do not modify the apiClient interceptor or the ADMIN_EMAIL check. cd /home/jonathan/Coding/cim_summary/frontend && npx tsc --noEmit --strict src/services/adminService.ts 2>&1 | head -20 Verify the file exports AlertEvent, ServiceHealthEntry, AnalyticsSummary interfaces and the four new methods adminService.ts exports 3 new typed interfaces and 4 new methods (getHealth, getAnalytics, getAlerts, acknowledgeAlert) alongside all existing functionality

Task 2: Create AlertBanner and AdminMonitoringDashboard components frontend/src/components/AlertBanner.tsx, frontend/src/components/AdminMonitoringDashboard.tsx **AlertBanner.tsx** — Create a new component at `frontend/src/components/AlertBanner.tsx`:

Props interface:

interface AlertBannerProps {
  alerts: AlertEvent[];
  onAcknowledge: (id: string) => Promise<void>;
}

Behavior:

• Filter alerts to show only status === 'active' AND alert_type is service_down or service_degraded (per RESEARCH Pitfall — recovery is informational, not critical)
• If no critical alerts after filtering, return null
• Render a red banner (bg-red-600 px-4 py-3) with each alert showing:
  • AlertTriangle icon from lucide-react (h-5 w-5, flex-shrink-0)
  • Text: {alert.service_name}: {alert.message ?? alert.alert_type} (text-sm font-medium text-white)
  • "Acknowledge" button with X icon from lucide-react (text-sm underline hover:no-underline)
• onAcknowledge called with alert.id on button click
• Import AlertEvent from ../services/adminService
• Import cn from ../utils/cn
• Use AlertTriangle and X from lucide-react

AdminMonitoringDashboard.tsx — Create at frontend/src/components/AdminMonitoringDashboard.tsx:

This component contains two sections: Service Health Panel and Processing Analytics Panel.

State:

const [health, setHealth] = useState<ServiceHealthEntry[]>([]);
const [analytics, setAnalytics] = useState<AnalyticsSummary | null>(null);
const [range, setRange] = useState('24h');
const [loading, setLoading] = useState(true);
const [error, setError] = useState<string | null>(null);

Data fetching: Use useCallback + useEffect pattern matching existing Analytics.tsx:

• loadData() calls Promise.all([adminService.getHealth(), adminService.getAnalytics(range)])
• Sets loading/error state appropriately
• Re-fetches when range changes

Service Health Panel:

• 2x2 grid on desktop (grid grid-cols-1 md:grid-cols-2 lg:grid-cols-4 gap-4)
• Each card: white bg, rounded-lg, shadow-soft, border border-gray-100, p-4
• Status dot: w-3 h-3 rounded-full with color mapping:
  • healthy → bg-green-500
  • degraded → bg-yellow-500
  • down → bg-red-500
  • unknown → bg-gray-400
• Service display name mapping: document_ai → "Document AI", llm_api → "LLM API", supabase → "Supabase", firebase_auth → "Firebase Auth"
• Show checkedAt as new Date(checkedAt).toLocaleString() if available, otherwise "Never checked"
• Show latencyMs with "ms" suffix if available
• Use Activity, Clock icons from lucide-react

Processing Analytics Panel:

• Range selector: <select> with options 24h, 7d, 30d — onChange updates range state
• Stat cards in 1x5 grid: Total Uploads, Succeeded, Failed, Success Rate (formatted as (successRate * 100).toFixed(1)%), Avg Processing Time (format avgProcessingMs as seconds: (avgProcessingMs / 1000).toFixed(1)s, or "N/A" if null)
• Include a "Refresh" button that calls loadData() — matches existing Analytics.tsx refresh pattern
• Use RefreshCw icon from lucide-react for refresh button

Loading state: Show animate-spin rounded-full h-8 w-8 border-b-2 border-accent-500 centered (matching existing App.tsx pattern). Error state: Show error message with retry button.

Import ServiceHealthEntry, AnalyticsSummary from ../services/adminService. Import adminService from ../services/adminService. Import cn from ../utils/cn. cd /home/jonathan/Coding/cim_summary/frontend && npx tsc --noEmit 2>&1 | head -30 Check that AlertBanner.tsx and AdminMonitoringDashboard.tsx exist and export their components AlertBanner renders critical alerts with acknowledge buttons; AdminMonitoringDashboard renders health status grid with colored dots and analytics summary with range selector and refresh

- `npx tsc --noEmit` passes with no type errors in the three modified/created files - AlertBanner exports a React component accepting `alerts` and `onAcknowledge` props - AdminMonitoringDashboard exports a React component with no required props - adminService exports AlertEvent, ServiceHealthEntry, AnalyticsSummary interfaces - adminService.getHealth(), getAnalytics(), getAlerts(), acknowledgeAlert() methods exist with correct return types

<success_criteria> All three files compile without TypeScript errors. Components follow existing project patterns (Tailwind, lucide-react, cn utility). Types match backend API response shapes exactly (camelCase for health/analytics, snake_case for alerts). </success_criteria>

After completion, create `.planning/phases/04-frontend/04-01-SUMMARY.md`
