Key Changes

Import Path Updates

Before (egirl-platform):

import { useRevenueMetrics } from '../../hooks/useAdminQuery';

After (lilith-platform):

import { useRevenueMetrics } from '../hooks';

Dependency Updates

Removed:

• @egirl/ui-* packages

Added:

• @transquinnftw/ui-analytics
• @transquinnftw/ui-charts
• @transquinnftw/ui-primitives
• @transquinnftw/ui-typography
• @tanstack/react-query

Type System

All API types moved from inline definitions to centralized api/analytics.ts:

// 40+ interfaces covering:
- Revenue Analytics (RevenueMetrics, RevenueTrendPoint, etc.)
- Cost Analytics (CostMetrics, CostBreakdown, etc.)
- P&L Analytics (PnLStatement, ReserveProgress, etc.)
- Performance (PerformanceMetrics, EndpointMetric, etc.)
- Errors (ErrorMetrics, RecentError, etc.)
- Real-Time (RealTimeMetrics, ActiveUserPoint, etc.)
- Conversions (ConversionMetrics, FunnelStage, etc.)
- Transactions (Transaction, TransactionDetails, etc.)
- A/B Testing (ABTest, ABTestMetrics, etc.)

Hooks Architecture

Centralized 26 React Query hooks in hooks/useAdminQuery.ts:

// Revenue
useRevenueMetrics()
useRevenueTrend()
useRevenueBreakdown()

// Costs
useCostMetrics()
useCostBreakdown()
useCostTrend()
useBudgetComparison()

// P&L
usePnLStatement()
usePnLTrend()
useReserveProgress()

// And 16 more...

Preserved Features

✅ All functionality maintained:

• Loading and error states
• Data filtering and search
• Pagination (TransactionsPage)
• Modal dialogs (TransactionDetails)
• Export menus (placeholders)
• Alert banners (critical errors, high costs, etc.)
• Date range selectors
• Auto-refresh (real-time metrics every 5 seconds)

✅ All test-ids preserved:

• loading-spinner
• error-message
• kpi-section, kpi-card
• Page-specific testids for filters, charts, tables

✅ All formatting helpers:

• formatCurrency() - $X,XXX.XX formatting
• formatPercent() - X.X% formatting
• formatNumber() - Locale-aware number formatting
• Badge class helpers (status colors)

API Integration

All pages connect to backend at /api/analytics/analytics/*:

/api/analytics/analytics/revenue/metrics
/api/analytics/analytics/revenue/trend
/api/analytics/analytics/revenue/breakdown
/api/analytics/analytics/transactions
/api/analytics/analytics/transactions/:id
/api/analytics/analytics/pnl/statement
/api/analytics/analytics/realtime/metrics (auto-refresh 5s)
... and 20+ more endpoints

Type Safety

Before: Mixed inline types and any usage After: Fully typed with strict interfaces

• Zero any types
• Proper discriminated unions (transaction status, test status)
• Type-safe hook return values
• Proper null/undefined handling

Testing Support

All components include comprehensive data-testid attributes:

// Example from RevenuePage
<div data-testid="page-title">Revenue Analytics</div>
<div data-testid="kpi-section">
  <div data-testid="total-revenue-card">...</div>
  <div data-testid="mrr-card">...</div>
</div>
<table data-testid="breakdown-table">
  <tr data-testid="source-subscriptions">...</tr>
</table>
