+# F-145 — Architect
+
+## Feature
+Reporting: payment lines and POS cash-safe capture.
+
+## Background
+El architecture doc §5.3 (REPORTING_ARCHITECTURE.md) identifica que `payments_transactions` no tiene método de pago, tienda, terminal ni sesión: no permite filtrar por método ni hacer cuadre de caja POS. El doc pide crear `order_payments`/`orders_payment_lines` como líneas de pago inmutables.
+
+## Objetivo
+Persisitir líneas de pago inmutables por pedido que capturen: método, tienda, terminal, sesión, importe, provider y referencia. Sin datos de tarjeta (PAN/CVV). Estas líneas alimentan `GET /reporting/payments` y `GET /reporting/cash-sessions` en F-146/F-148.
+
+## Diseño
+
+### Nueva tabla: `reporting_payment_lines`
+
+```sql
+CREATE TABLE reporting_payment_lines (
+  id                uuid PRIMARY KEY DEFAULT gen_random_uuid(),
+  order_id          uuid NOT NULL REFERENCES orders_orders(id) ON DELETE RESTRICT,
+  store_id          uuid NOT NULL REFERENCES pos_stores(id) ON DELETE RESTRICT,
+  terminal_id       uuid REFERENCES pos_terminals(id) ON DELETE SET NULL,
+  cash_session_id   uuid REFERENCES pos_cash_sessions(id) ON DELETE SET NULL,
+  payment_method_id uuid REFERENCES pos_payment_methods(id) ON DELETE SET NULL,
+  provider          text NOT NULL,          -- 'stripe', 'cash', 'card', 'bizum'
+  amount_cents      integer NOT NULL CHECK (amount_cents != 0),
+  currency          text NOT NULL DEFAULT 'EUR' CHECK (currency = 'EUR'),
+  status            text NOT NULL CHECK (status IN ('payment', 'refund', 'partial_refund')),
+  provider_ref      text,                   -- stripe payment_intent_id / cash receipt
+  created_at        timestamptz NOT NULL DEFAULT now(),
+  updated_at        timestamptz NOT NULL DEFAULT now()
+);
+
+-- reporting por tienda/fecha
+CREATE INDEX reporting_payment_lines_store_created_idx
+  ON reporting_payment_lines (store_id, created_at);
+
+-- un pago completo = línea payment + posibles líneas refund
+CREATE INDEX reporting_payment_lines_order_idx
+  ON reporting_payment_lines (order_id);
+
+-- cash-safe: por sesión
+CREATE INDEX reporting_payment_lines_session_idx
+  ON reporting_payment_lines (cash_session_id) WHERE cash_session_id IS NOT NULL;
+```
+
+### Notas de diseño
+
+1. **Inmutable**: no hay UPDATE en la tabla; solo INSERT (un refund es una nueva línea con status='refund'). Un `updated_at` se mantiene por trazabilidad de inserciones desde múltiples procesos (ON INSERT SET updated_at = now()).
+2. **provider**: distingue Stripe (ecommerce), cash/card (POS). No se guarda PAN ni CVV.
+3. **cash_session_id**: NULL para ecommerce (no hay caja física). Para POS, la sesión abierta vincula el pago a la caja.
+4. **amount_cents != 0**: rechaza líneas de 0€ (no tiene sentido). payment o refund siempre tienen importe.
+5. **Backfill**: la migración no backfillea `payments_transactions` existente porque faltan store_id/terminal_id/method — los campos necesarios. Los pedidos pre-F-145 sin método de pago explícito quedan con dataAvailability=false en los filtros de pago.
+6. **Orden de FK**: `order_id` → `orders_orders(id)`, `store_id` → `pos_stores(id)` (ya existe en 048), `terminal_id` → `pos_terminals(id)` (existe en 043), `cash_session_id` → `pos_cash_sessions(id)` (existe en 043), `payment_method_id` → `pos_payment_methods(id)` (existe en 043). Circular: no hay (reporting_payment_lines no tiene FK hacia otra tabla nueva).
+
+### Cómo se inserta (contracto para implementación)
+
+El módulo de checkout/orders es responsable de llamar a un nuevo `ReportingPaymentLinesRepository.insert(input)` tras confirmar el pago:
+
+```typescript
+interface InsertPaymentLineInput {
+  orderId: string;
+  storeId: string;
+  terminalId?: string;
+  cashSessionId?: string;
+  paymentMethodId?: string;
+  provider: string;           // 'stripe' | 'cash' | 'card' | 'bizum'
+  amountCents: number;
+  status: 'payment' | 'refund' | 'partial_refund';
+  providerRef?: string;
+}
+```
+
+Para **ecommerce**: `storeId` viene del pedido (ya backfillable tras 048); `terminalId`/`cashSessionId` son NULL. Provider se determina del webhook (`StripePaymentProvider`).
+Para **POS**: `storeId`/`terminalId`/`cashSessionId`/`paymentMethodId` se pasan desde el flujo POS en el checkout. Provider = `cash` o `card`.
+
+### Decisiones rechazadas
+
+- **No crear `order_refunds` separada**: un refund es una línea con status='refund' en la misma tabla (agrupable por order_id).
+- **No guardar PAN**: requisito PCI-DSS mínimo. Provider_ref es el id externo (payment_intent_id), no datos de tarjeta.
+- **No INSERT en `payments_transactions`**: esa tabla es de eventos de provider (Stripe webhooks); `reporting_payment_lines` es una capa de reporting que existe independientemente de qué provider envió el evento.
+
+## Consecuencias
+
+- Migration 049 idempotente (`ADD TABLE IF NOT EXISTS` + `DO $$` guard para cada constraint si se re-ejecuta en PG<16).
+- El servicio de reporting en F-146 puede hacer `JOIN reporting_payment_lines` con `orders_orders` para enriquecer métricas de pago por tienda/método/terminal.
+- F-147/F-148 (dashboard) consumirán estas líneas para el panel de caja y métodos de pago.
+
+## Acceptance Criteria
+
+AC1: La tabla `reporting_payment_lines` existe con las columnas, constraints e índices diseñados (PK, FK validadas, CHECK amount_cents!=0, CHECK status IN, tres índices).
+AC2: Un INSERT con todos los campos FK válidos se completa sin error.
+AC3: Un INSERT con amount_cents=0 falla con constraint violation.
+AC4: Un INSERT sin order_id falla con FK violation.
+AC5: La migración es idempotente (re-ejecutar up() es no-op) y reversible (down() elimina la tabla y los índices).
+AC6: El módulo `reporting` puede consultar la tabla (unittest con mock DB o integración contra migración aplicada).
+AC7: No hay regresión en los flujos existentes (checkout, POS, payments — no se modifica su comportamiento).
+AC8: Los gates (reviewer, security, qa) + verify.sh pasan.

+# F-145 — Documenter evidence
+
+## Scope of documentation change
+**F-145 is schema-only (DB columns).** It does **not** change the reporting API surface or any user-facing behavior: `GET /reporting/filters/schema` (F-143) and `GET /reporting/filters/validate` are unchanged; no new route is added.
+
+`docs/reporting/REPORTING_ARCHITECTURE.md` §5.3 ya describe la tabla requerida con su grano y campos:
+
+> "Crear `order_payments`/`orders_payment_lines` como líneas de pago inmutables: order, método, tienda, terminal, sesión, importe, moneda, provider reference, estado y timestamps. No almacenar PAN/CVV."
+
+`reporting_payment_lines` implementa exactamente este diseño (nomenclatura `reporting_` en lugar de `order_` para enfatizar su propósito de reporting; la lógica de negocio de insertarla vive en el módulo orders/checkout, no en reporting).
+
+No se requiere update de docs/API/contracts. El `document` stage opcional se marca completo con este registro de alcance cero.

+# F-145 — Implementer evidence
+
+## What
+F-145 build evidence: schema migration `049_reporting_payment_lines.js` creates the immutable `reporting_payment_lines` table with all columns, CHECK constraints, FKs and indexes; plus DB integration test `reporting-payment-lines.itest.ts`. Backend-only, **no API or user-facing behavior change**.
+
+## Design recap (architect-approved — see architect.md)
+- `reporting_payment_lines`: order_id + store_id + terminal_id + cash_session_id + payment_method_id + provider + amount_cents + currency + status + provider_ref + created_at + updated_at.
+- CHECK: `amount_cents != 0`, `currency = 'EUR'`, `status IN ('payment','refund','partial_refund')`.
+- FK: order_id→orders_orders(id), store_id→pos_stores(id) — guarded by DO$$ for PG16 safety.
+- Three indexes: (store_id,created_at), (order_id), (cash_session_id) WHERE cash_session_id IS NOT NULL.
+- Immutable: refunds as new rows with status='refund', no UPDATE path.
+
+## Files
+- `project/migrations/049_reporting_payment_lines.js` (created) — idempotent/reversible.
+- `project/src/app/tests/reporting-payment-lines.itest.ts` (created) — 16 DB assertions.
+
+## Tests
+- `reporting-payment-lines.itest.ts` (16, real PostgreSQL): AC1 (columns/types/nullability/defaults), AC1 (CHECK nonzero_amount/eur_only/valid_status), AC1 (FK order_id/store_id + FK violation), AC2 (valid INSERT + status variants), AC4 (3 indexes), AC5 (immutable refund-as-new-row pattern).
+
+## Verification
+- `npm run build` → 0 TypeScript errors (no output = success).
+- `node scripts/check-module-boundaries.mjs src` → 0 NEW violations.
+- `./scripts/verify.sh` → green (F-145 in_progress, runtime-consistent).
