# F-146 — Implementer evidence
## What
F-146 build evidence: `ReportingService` (summary + sales) con CTEs SQL parametrizados, rutas `GET /reporting/summary` y `GET /reporting/sales`, tests unitarios 44/44 (reporting-service.test.ts 14 + reporting.routes.test.ts 15 + existing tests). Backend-only, no schema migration.
## Files
- `src/modules/reporting/application/reporting-service.ts` (created) — ReportingService con métodos summary() y sales().
- `src/modules/reporting/api/reporting.routes.ts` (updated) — añade summary + sales endpoints.
- `src/modules/reporting/api/reporting.routes.test.ts` (updated) — 8 tests nuevos para summary/sales.
- `src/modules/reporting/tests/reporting-service.test.ts` (created) — 14 unit tests con mock pg.Pool.
- `src/modules/reporting/index.ts` (updated) — re-exports ReportingService y tipos.
- `src/app/build-app.ts` (updated) — pasa pool a registerReportingRoutes.
## Tests
- reporting-service.test.ts: 14 unit tests (mock pg.Pool) cubriendo summary(), sales(), filtros, paginación, groupBy (day/week/month/channel/store), dataAvailability.
- reporting.routes.test.ts: 15 route tests (7 pre-existentes + 8 nuevos para summary/sales con mock pool).
- Módulo completo: 44 tests passing.
## Verification
- `npm run build` → 0 TypeScript errors.
- `node scripts/check-module-boundaries.mjs src` → 0 NEW violations.
- `./scripts/verify.sh` → green (F-146 in_progress, runtime-consistent).
- Backlog: F-146 in_progress started via new_ticket.py --start F-146.
