+# F-146 — Architect
+
+## Feature
+Reporting: service summary and sales API.
+
+## Background
+F-143 set up the RBAC and filter contracts. F-144 added store_id/shipping_cents snapshots. F-145 added payment lines. F-146 wires up the ReportingService that reads the actual data using those columns.
+
+## Objetivo
+Implementar ReportingService con métodos `summary()` y `sales()` que:
+- Usan el CTE `filtered_orders` del architecture doc §7
+- Aplican todos los filtros del schema de F-143
+- Devuelven métricas con `dataAvailability` correcto
+- Soportan `groupBy`, `pagination` y `compare`
+
+## Diseño
+
+### ReportingService (application layer)
+
+```typescript
+// src/modules/reporting/application/reporting-service.ts
+
+interface ReportingServiceDeps {
+  pool: pg.Pool;
+}
+
+class ReportingService {
+  constructor(private deps: ReportingServiceDeps) {}
+  
+  async summary(filters: ReportingFilters): Promise<SummaryResponse>
+  async sales(filters: ReportingFilters): Promise<SalesResponse>
+}
+```
+
+### SQL base (CTE de §7 arquitectura)
+
+```sql
+WITH filtered_orders AS (
+  SELECT o.*
+  FROM orders_orders o
+  WHERE o.created_at >= $1             -- from (UTC)
+    AND o.created_at < $2              -- to (UTC)
+    AND o.state IN ('PAID','PROCESSING','SHIPPED','DELIVERED','COMPLETED')
+    AND ($3::text IS NULL OR o.source = $3)  -- channel
+    AND (cardinality($4::uuid[]) = 0 OR o.store_id = ANY($4::uuid[]))
+    AND (cardinality($5::uuid[]) = 0 OR o.terminal_id = ANY($5::uuid[]))
+    AND (cardinality($6::text[]) = 0 OR o.state = ANY($6::text[]))
+),
+filtered_items AS (
+  SELECT i.*, o.source, o.store_id, o.terminal_id
+  FROM orders_items i
+  JOIN filtered_orders o ON o.id = i.order_id
+)
+SELECT
+  COUNT(DISTINCT o.id)::int             AS orders,
+  COUNT(DISTINCT o.user_id) FILTER (WHERE o.user_id IS NOT NULL)::int AS customers,
+  COALESCE(SUM(i.unit_price_cents * i.quantity), 0)::bigint AS gross_sales_cents,
+  COALESCE(SUM(i.discount_cents), 0)::bigint             AS discounts_cents,
+  COALESCE(SUM(i.tax_cents), 0)::bigint                 AS tax_cents,
+  COALESCE(SUM(i.quantity), 0)::int                     AS units_sold
+FROM filtered_orders o
+LEFT JOIN filtered_items i ON i.order_id = o.id
+```
+
+### groupBy extension (sales endpoint)
+
+```sql
+-- Para groupBy=day (agrupación por día UTC)
+DATE_TRUNC('day', o.created_at) AS period
+```
+
+### dataAvailability (según modelo actual)
+
+```typescript
+const dataAvailability: DataAvailability = {
+  grossSales: 'available',
+  netSales: 'unavailable',      // sin shipping_cents aún (F-144 existe, service aún no lo usa)
+  discounts: 'available',
+  tax: 'available',
+  unitsSold: 'available',
+  orders: 'available',
+  customers: 'available',
+  margin: 'unavailable',        // sin cost_at_sale en orders_items
+  paymentMethod: 'unavailable',  // sin JOIN con reporting_payment_lines aún
+  refunds: 'unavailable',       // necesita state=REFUNDED/PARTIALLY_REFUNDED en filtro
+  shipping: 'available',        // shipping_cents en orders_orders (F-144)
+};
+```
+
+### Rutas
+
+- `GET /reporting/summary?from=&to=&channel=&storeId=&...` → SummaryResponse
+- `GET /reporting/sales?from=&to=&groupBy=day&page=1&...` → SalesResponse (con pagination)
+
+### Caching
+
+F-146 NO implementa caché (postergado a F-148 post-dashboard). La respuesta incluye `updatedAt: new Date().toISOString()` y `cache: { hit: false, maxAgeSeconds: 0 }` como placeholder.
+
+## Acceptance Criteria
+
+AC1: GET /reporting/summary devuelve métricas agregadas (orders, customers, grossSales, discounts, tax, units) con rango filtrado.
+AC2: GET /reporting/sales devuelve filas agrupadas por día/semana/mes/hora/store/channel.
+AC3: Filtros storeId/terminalId/state/channel se aplican correctamente.
+AC4: Paginación funciona (page/pageSize).
+AC5: dataAvailability refleja correctamente qué métricas son calculables.
+AC6: Compare previous_equal devuelve rango previo del mismo tamaño.
+AC7: Errores de validación (fechas invertidas, IDs inválidos) devuelven 400.
+AC8: Permisos RBAC aplicados (REPORTING_VIEW para summary, REPORTING_SALES para sales).
+AC9: tsc 0, itest pasa, verify.sh verde.

+# F-146 — Documenter evidence
+
+## Scope of documentation change
+F-146 implementa los endpoints `GET /reporting/summary` y `GET /reporting/sales`. La arquitectura en `docs/reporting/REPORTING_ARCHITECTURE.md` §6 (contrato API) y §7 (CTE base) ya describe estos endpoints con sus query params y respuesta. La documentación existente es correcta; no se requiere update adicional en este ticket.
+
+El único gap conocido es que `dataAvailability.paymentMethod` seguirá `unavailable` hasta que F-146+ haga JOIN con `reporting_payment_lines` (F-145) en el servicio. Esto se documenta vía el campo `dataAvailability.paymentMethod = 'unavailable'` en la respuesta — el cliente sabe que no está disponible.
+
+`docs/reporting/REPORTING_ARCHITECTURE.md` §8 (Frontend Admin) menciona los componentes del dashboard (`ReportingFilters`, `KpiCard`, etc.) y las rutas (`/reporting/sales`). Estas rutas están ahora implementadas en backend. El `document` stage opcional se marca completo con este registro de alcance.

+# 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.

+| AC8 RBAC | ✅ | customer forbidden 403 en summary y sales |
+| AC9 tsc/tests/verify | ✅ | tsc 0, 44 tests, verify verde |
