+
+## What
+F-148 build evidence: Admin reporting dashboard with sales trends (SVG bar chart), channel breakdown (ecommerce/POS/admin), and top stores/terminals tables. Built on F-147 DateRangePicker and F-146 ReportingService.
+
+## Files

+- `apps/admin/src/components/reporting/TrendChart.tsx` (created) — SVG bar chart
+- `apps/admin/src/components/reporting/ChannelBreakdown.tsx` (created) — channel cards
+
+## Verification
+- `npx tsc --noEmit` (admin app) → 0 TypeScript errors.
+- `./scripts/verify.sh` → green (F-148 in_progress, runtime-consistent).
