+ * F-144 — Reporting snapshots: store_id, shipping_cents, cost & VAT line snapshots
+ *
+ * Adds the snapshot columns needed to report multi-store sales without
+ * rewriting history (REPORTING_ARCHITECTURE.md §5 "store/VAT/cost/shipping"):
+ *   - orders_orders.store_id          -> uuid NOT NULL, FK -> pos_stores, default store.
+ *   - orders_orders.shipping_cents    -> integer NOT NULL DEFAULT 0 (shipping split out).
+ *   - orders_items.cost_at_sale_cents -> bigint  (nullable; NULL until backfilled).
+ *   - orders_items.vat_rate          -> text    (nullable snapshot of the VAT key).
+ *
+ * store_id gets a column DEFAULT of the well-known default store (seeded by
+ * migration 043_pos_basics), so both pre-existing rows and new inserts that
+ * don't specify a store inherit the default — no full table rewrite, no
+ * app-layer change to the order INSERT path. The FK is created with a `DO $$`
+ * guard (same idiom as 047/046) because PG16 does not support
+ * `ADD CONSTRAINT IF NOT EXISTS`; the guard makes `up` safely re-runnable.
+ *
+ * Idempotent: columns/index use `IF NOT EXISTS`; the FK is guarded by
+ * `DO $$ IF NOT EXISTS ... $$`. Reversible: down() drops everything.
+ *
+ * @param {import('node-pg-migrate').MigrationBuilder} pgm

-### AC1 — contrato de filtros
-- `GET /reporting/filters/schema` (admin) → 200 → `{ filterSchema, comparison, dataAvailability, permissions }`.
-- `comparison.modes` incluye `none`, `previous_equal`, `previous_calendar`.
-- `comparison.rangeBounds === 'inclusive_start_exclusive_end'`.
-- `dataAvailability` refleja el baseline F-142 (grossSales/discounts/tax/unitsSold/orders/customers `available`; netSales/margin/paymentMethod/refunds/shipping `unavailable`).
-- `filterSchema.filters` incluye `storeId` (repeatable, uuid), `compare`, `channel`, `groupBy`, `page`, `pageSize`.
+## AC1 — store_id multi-tienda (snapshot, no rewrite)
+- `orders_orders.store_id` es `uuid NOT NULL DEFAULT '00000000-0000-0000-0000-000000000001'::uuid`.
+- FK `orders_orders_store_id_fkey → pos_stores(id)` existe y es `VALID`.
+- Índice `orders_orders_store_id_created_at_idx ON orders_orders(store_id, created_at)` existe.
+- Filas existentes heredan el default store (no table rewrite de datos).
+- Un `INSERT INTO orders_orders DEFAULT VALUES` persiste `store_id = DEFAULT_STORE_ID`.
 
-### AC2 — RBAC (backend-authority)
-- `customer` (role customer) → 403 en `/reporting/filters/schema` y `/reporting/filters/validate`.
-- `admin` y `editor` → 200 en `/reporting/filters/schema` (tienen `REPORTING_VIEW`).
-- `admin`/`editor`/`pos_manager`/`pos_cashier` → 200 en `/reporting/filters/validate` (tienen `REPORTING_SALES`).
-- `customer` NO aparece en `REPORTING_ROLE_PERMISSIONS` con permisos.
+## AC2 — shipping_cents separado
+- `orders_orders.shipping_cents` es `integer NOT NULL DEFAULT 0`.
+- Filas existentes mantienen su `total_cents` (no se altera; shipping_cents = 0).
+- El `INSERT ... DEFAULT VALUES` registra `shipping_cents = 0`.
 
-### AC3 — parseo + rango `[from,to)`
-- `GET /reporting/filters/validate?from=2026-08-01T00:00:00Z&to=2026-08-31T23:59:59Z&compare=previous_equal` → 200 → `filters.range.from/to` normalizados; `comparison.range.from` < `filters.range.from` < `filters.range.to`; `comparison.range.to` === `filters.range.from`.
-- `pageSize` y `page` vienen por defecto (1 y 50) cuando no se pasan.
+## AC3 — snapshots de línea (cost_at_sale_cents, vat_rate)
+- `orders_items.cost_at_sale_cents` es `bigint`, nullable (NULL para filas históricas → margen `unavailable`).
+- `orders_items.vat_rate` es `text`, nullable (snapshot del tipo IVA aplicado; NULL → IVA-por-tipo `unavailable`).
+- No se reescribe la historia: columnas nuevas no tocan datos existentes.
 
-### AC4 — validación
-- `from > to` → 400 (`VALIDATION_ERROR` / 400).
-- `?storeId=<single uuid>` parsea a array de 1 elemento; `?storeId=a&storeId=b` a array de 2.
-- UUID inválido → 400.
+## AC4 — migración idempotente y reversible
+- `up()` es no-op si se re-ejecuta (DDL `IF NOT EXISTS` / `DO $$` guards).
+- `down()` elimina índice, constraint y columnas nuevas.
 
-### AC5 — comparison modes (unit)
-- `comparisonRange(range, 'none')` === `null`.
-- `previous_equal`: `to_prev === from_actual`, `from_prev === from_actual - duration`.
-- `previous_calendar`: ventana alineada a UTC, `to_prev <= from_actual`.

+  columnas, nullabilidad, defaults, FK (contype='f') e índice vía
+  `information_schema`/`pg_constraint`/`pg_indexes`, más un insert
+  `DEFAULT VALUES` con backfill de `store_id`/`shipping_cents`.
 
-### AC6 — granularidad de permisos
-- `REPORTING_FINANCIAL` concedido solo a `admin` (editor/pos_manager/pos_cashier → 403).
-- `requireReportingPermission` lanza AppError(403) para roles sin el permiso.
+## AC6 — verificación de gates

-## Estado
-Diseño aprobado (ver `work/artifacts/F-143/architect.md`). Implementación backend-only.
+## Reporting: snapshots de tienda, IVA, coste y envío
 
-## Producto (alcance)
-El módulo `reporting` expone el **contrato compartido** de filtros de reporte y la **matriz de permisos `REPORTING_*`** como código, para que los endpoints de reporte futuros (F-144+) consuman un parser único y estén consistentes. **No genera reportes ni lectura de datos** (esas son F-144+).
+**Alcance:** backend-only. Añade las columnas mínimas de *snapshot* que el
+módulo `reporting` (F-143↑, F-146 services) necesita para reportar ventas
+multi-tienda sin reescribir la historia (REPORTING_ARCHITECTURE.md §5).
 
-## Alcance (entregable)
-- Schema zod reusable `reportingFiltersSchema` (`from`, `to`, `compare`, `channel`, `storeId`, `terminalId`, `cashierId`, `paymentMethodId`, `productId`, `categoryId`, `brandId`, `customerId`, `state`, `groupBy`, `page`, `pageSize`, `sort`) con validación `from<to` y semántica `[from,to)`.
-- Parser `parseReportingFilters` + helper `comparisonRange` (`none | previous_equal | previous_calendar`).
-- Metadato `REPORTING_FILTER_META` (campos, modos de comparación, groupBy, paginación, `dataAvailability`) servido a `GET /reporting/filters/schema`.
-- Permisos backend `REPORTING_*` basados en roles (`requireReportingPermission`) con matriz `admin/editor/pos_manager/pos_cashier/customer`.
-- Rutas: `GET /reporting/filters/schema` (requiere `REPORTING_VIEW`), `GET /reporting/filters/validate` (requiere `REPORTING_SALES`).
+## Historias
 
-## Fuera de alcance (F-144+)
-- Lectura de datos transaccionales, agregaciones, dashboards, exportaciones, tabla de permisos en BD (F-142 §9 la marca como migración futura; hoy es role-based con los mismos call sites).
+- Como **analista multi-tienda**, quiero que cada pedido (`orders_orders`)
+  tenga `store_id` (tienda donde se vendió), para poder filtrar y agrupar
+  reportes por tienda sin reescribir histórico.
+- Como **reportista de márgenes**, quiero que el importe del envío
+  (`shipping_cents`) esté separado del `total_cents`, para poder exponer
+  “ventas de mercancía” y “net sales” con nombres correctos (§5.6).
+- Como **analista financiero**, quiero un *snapshot* del tipo de IVA
+  (`vat_rate`) y del coste (`cost_at_sale_cents`) por línea, para poder
+  calcular margen histórico e IVA por tipo (§5.2). Estos snapshots son
+  **nullable**: hasta que se poblén, margen/IVA-por-tipo permanecen
+  `unavailable` (nunca se publican como 0).
 
-## API (contrato HTTP)
-- `GET /reporting/filters/schema` → `{ filterSchema, comparison, dataAvailability, permissions: { role, grants } }`. Requiere `REPORTING_VIEW`.
-- `GET /reporting/filters/validate?from=...&to=...&compare=...&...` → `{ ok, filters, comparison: { range } }`. Requiere `REPORTING_SALES`.
+## Non-goals (fuera de F-144)
+- Poblar `cost_at_sale_cents`/`vat_rate` en el flujo de venta (F-146 /
+  reporting-service snapshots).
+- Crear la tabla de payment lines ni refunds (F-145 y el roadmap §5.3-4).
+- Cualquier endpoint de reporte ni cálculo de métricas (F-146).
+- Resolver explícitamente la tienda en el checkout (writes app-layered) — se
+  usa el DEFAULT de columna como mínimo; F-146 introduce la resolución de
+  tienda por request.
 
-## Seguridad (F-143 es parte de éste)
-- La matriz RBAC se impone en backend (`requireReportingPermission` sobre `CurrentUser.role`). El frontend no es autoridad.
-- `customer` → 0 permisos → 403 siempre.
-- Futuro: migrar a tabla `backoffice_permissions` sin cambiar `requireReportingPermission(user, permission)`.
-
-## Referencias
-- Arquitectura Reporting (F-142): `docs/reporting/REPORTING_ARCHITECTURE.md` (§4–§11).
-- Patrones: `src/modules/pricing/api/pricing.routes.ts`, `src/shared/auth.ts`, `src/shared/http-input.ts`.
+## Fuente de verdad
+`orders_orders` y `orders_items` en PostgreSQL (`postgres:16`). La tienda
+default (`id = 00000000-0000-0000-0000-000000000001`) es sembrada por
+`043_pos_basics` y reutilizada desde `src/modules/inventory/index.ts`
+(`DEFAULT_STORE_ID`).

+estilo `043_pos_basics`/`047_*`) idempotente y reversible. **No hay migración de
+datos costosa**: `store_id` usa column `DEFAULT` del default store (sembrado por

+table rewrite ni toque en el app-layer.
 
-## Boundaries (R1/R2)
-- `reporting` importa SOLO `shared/*` + `zod` → **ningún otro módulo**. ✓ R1.
-- `src/app/build-app.ts` importa `registerReportingRoutes` (+ tipos) desde `modules/reporting/index.js` (R2). ✓.
-- Registrado dentro de `if (deps.pool)` con `authenticate: combinedAuth` (backplane backoffice), junto al resto de módulos backoffice.
+## Columnas nuevas
 
-## Filter contract (F-142 §6)
-- Rango `[from,to)`: `from` inclusivo, `to` exclusivo → evita doble conteo.
-- `from`/`to`: ISO datetime with offset → `z.string().datetime({ offset: true })`.
-- Arrays repetibles de UUID aceptan single OR array vía `z.preprocess((v)=>Array.isArray(v)?v:v===undefined?undefined:[v], z.array(z.uuid()).optional())`.
-- `compare` default `none`; `channel` default `all`; `page` (1..); `pageSize` (1..200, default 50).
-- `from > to` → refine → AppError(400) (mapeado por `parseJson`).

-- `previous_equal` → shift ventana atrás por la duración exacta (`[start-duration, start)`).
-- `previous_calendar` → shift atrás por los días calendario transcurridos, alineado a UTC (`00:00`) → `[prevStart, prevStart+spanDays)`. Documented como aproximación calendar-aligned.

-- pos_manager → VIEW+SALES+PAYMENTS+CASH.
-- pos_cashier → VIEW+SALES.
-- customer → [] (403).
-- `requireReportingPermission(user, permission)` lanza AppError(403). Futuro: tabla `backoffice_permissions`; la firma no cambia.
+## Idempotencia + reversibilidad
+- Toda la DDL: `ADD COLUMN IF NOT EXISTS` / `DO $$ IF NOT EXISTS` sobre
+  `pg_constraint`. Re-ejecutar es no-op.
+- `down()`: `DROP INDEX`, `DROP CONSTRAINT`, `DROP COLUMN` por cada nueva
+  columna (orden inverso de dependencias).
 
-## Data availability (F-142 §4 baseline, server-truth)
-`grossSales/discounts/tax/unitsSold/orders/customers = available`; `netSales/margin/paymentMethod/refunds/shipping = unavailable`. Se expone via `REPORTING_FILTER_META.dataAvailability` (no cálculos aún — F-144+).
+## Por qué DEFAULT (no NOT NULL sin default + UPDATE)
+- `store_id` es una columna nueva: no hay histórico que "reescribir". Un
+  `DEFAULT` constante backfilla silenciosamente y evita un `UPDATE` table-scan
+  sobre tabla potencialmente grande — alineado con §11 "no añadir índices
+  duplicados indiscriminadamente" y con no-rewrite-history.
+- El app **inserta pedidos** vía `PgOrderRepository` (raw SQL `INSERT INTO
+  orders_orders (...)`). Con column `DEFAULT`, ese INSERT sigue funcionando
+  (la column no aparece en la lista) → cero regresión en checkout/orders.itest.
+  La resolución explícita de tienda (writes app-layered) se deja a F-146.
+
+## Test
+- itest `reporting-snapshots.itest.ts` (mirror `inventory.itest.ts`):
+  `recreateDatabase(url)` + `runMigrations(url,'up')` (aplica 048 contra
+  `mercadodevida_test`) + `createPool`, con `describe.skipIf(!hasDb)`.
+- Asocia columnas/nullabilidad/default/FK/índice vía `information_schema` /
+  `pg_constraint` / `pg_indexes`, e inserta `INSERT INTO orders_orders DEFAULT
+  VALUES RETURNING store_id, shipping_cents` → `store_id = DEFAULT_STORE_ID`,
+  `shipping_cents = 0`.
+- Harness: `TEST_DATABASE_URL=postgres://mdv:mdv_dev_only@localhost:5432/mercadodevida_test`
+  (verificado: `orders.itest.ts` recrea+migra+tests en ~450ms con el

+# F-144 — Architecture decision record
+
+## Context
+REPORTING_ARCHITECTURE.md §5 lista los *snapshots* mínimos necesarios para
+reportar ventas multi-tienda sin reescribir historia. `orders_orders` carece de
+`store_id` (§5.1 riesgo #1), no separa envío de `total_cents` (§5.6) y
+`orders_items` no guarda `cost_at_sale_cents`/`vat_rate` snapshots (§5.2, §5.9).
+
+## Decision
+Una migración idempotente `048_*` añade las columnas de *snapshot* como columnas
+nuevas de tabla:
+
+- `orders_orders.store_id uuid NOT NULL DEFAULT <default store>` con FK →
+  `pos_stores(id)` VALID. El default store (`00000000-0000-0000-0000-000000000001`)
+  está sembrado por `043_pos_basics` (ON CONFLICT), por lo que el backfill de
+  filas existentes y los inserts futuros sin store_id heredan el default sin un
+  `UPDATE` table-scan ni toque en el app-layer. La resolución explícita de tienda

+- `orders_items.cost_at_sale_cents bigint` y `orders_items.vat_rate text`, ambos

+## Consequences
+- Positivas: columna `DEFAULT` evita table rewrite y mantiene `PgOrderRepository`
+  (raw `INSERT INTO orders_orders (...)`) 100% compatible → cero regresión en
+  checkout/orders itests; el default store existe al subir la migración (043
+  precede a 048) → FK VALID siempre tiene un target válido.
+- Nuevas limitaciones: `store_id` no se resuelve por request en F-144 (usa el
+  default); `cost_at_sale_cents`/`vat_rate` quedan NULL (población en F-146).
+  Ambas son explícitas en `dataAvailability` del reporting contract (F-143).
+- Reversible: `down()` elimina índice/FK/columnas; idempotente vía `IF NOT
+  EXISTS`/`DO $$`.
+
+## Evidence of design
+- `orders_orders` esquema actual (16 columnas, sin store_id/shipping_cents) —
+  inspeccionado en `mercadodevida` dev DB.
+- `pos_stores` default store sembrado por 043; `DEFAULT_STORE_ID` reutilizado desde
+  `src/modules/inventory/index.ts`.

+# F-144 — Documenter evidence
+
+## Scope of documentation change
+**F-144 is schema-only (DB columns).** It does **not** change the reporting API surface or any user-facing behavior: `GET /reporting/filters/schema` and `GET /reporting/filters/validate` (F-143) are unchanged, and no new route is added.
+
+## What was already documented (no update needed)
+`docs/reporting/REPORTING_ARCHITECTURE.md` §5 ya describe los snapshots requeridos y el riesgo:
+- §5.1 (p.22): `orders_orders` "No tiene `store_id` directo" → cubierto por F-144 (ahora `store_id`).
+- §5.2 / §5.9 (p.23): `orders_items` "No guarda `cost_at_sale`, tipo de IVA, marca/categoría snapshot" → F-144 añade `cost_at_sale_cents` + `vat_rate` (marca/categoría postergados a F-145/F-146).
+- §5.6 (p.83-88): "Ventas netas sin portes" / "IVA por tipo" / "Margen histórico" → F-144 añade `shipping_cents` separado + snapshots de coste/IVA (nulos hasta F-146).
+- SQL esperado (p.97-98, 101-102, 194, 198): `store_id` NOT NULL + index, `cost_at_sale_cents`/`vat_rate` nullable, `shipping_cents`. Todo implementado tal cual.
+- dataAvailability sigue siendo metadata-only (F-138 §4 / F-143 §4): valores nulos se exponen como `unavailable`, NUNCA como 0 → invariante preservada.
+
+## Decision
+No se requiere update de docs/API/contracts/user-facing notes. El `document` stage se marca completo con este registro de alcance cero, consistente con el gate `document` (optional) de `harness/workflow.stages.yml`. La evasión intencional del `ADD CONSTRAINT IF NOT EXISTS` (no soportado por PG16) hacia el `DO $$` guard quedó registrada en `architect.md` §Consequences y en `work/artifacts/F-144/implementer.md`.

+# F-144 — Implementer evidence
+
+## What
+F-144 build evidence: an additive schema migration `048_*` adds the store/VAT/cost/shipping snapshot columns to `orders_orders` / `orders_items`, plus DB integration test `reporting-snapshots.itest.ts`. Backend-only, **no API or user-facing behavior change** (reporting routes are unchanged from F-143).
+
+## Design recap (architect-approved — see architect.md)
+- `orders_orders.store_id` `uuid NOT NULL DEFAULT <default store>` with guarded FK → `pos_stores(id)` + index `(store_id, created_at)`. Column DEFAULT backfills existing rows and future inserts without a table rewrite and without app-layer changes to the order INSERT path. FK resolución por request se posterga a F-146.
+- `orders_orders.shipping_cents` `integer NOT NULL DEFAULT 0` separa envío del total (sin sobreescritura: históricos → 0, `total_cents` intacto).
+- `orders_items.cost_at_sale_cents` `bigint` y `orders_items.vat_rate` `text`, **nullable** (snapshots → NULL hasta poblados; margen/IVA-por-tipo permanecen `unavailable`, nunca 0).
+- `up()` idempotente: `ADD COLUMN IF NOT EXISTS` (PG>=9.6) + `DO $$ IF NOT EXISTS ... $$` guard para el FK (PG16 no admite `ADD CONSTRAINT IF NOT EXISTS`). `down()` reversible (índice/constraint/columnas).
+
+## Files
+- `project/migrations/048_reporting_store_shipping_snapshots.js` (created) — `up`/`down` idempotent/reversible. El FK usa `DO $$` guard (convención 047/046) tras confirmar via psql que el bloque DO es SQL válido en PG16.15.
+- `project/src/app/tests/reporting-snapshots.itest.ts` (created) — recrea la DB (drop+recreate), migra `001→048`, verifica schema vía `information_schema`/`pg_constraint`/`pg_indexes`, e inserta revertindo el CHECK de 047.
+
+## Tests
+- NEW `reporting-snapshots.itest.ts` (3, real PostgreSQL): AC1 (store_id col NOT NULL + DEFAULT + FK contype='f' + índice + INSERT backfill store_id=DEFAULT_STORE_ID), AC2 (shipping_cents NOT NULL DEFAULT 0 + backfill=0), AC3 (cost_at_sale_cents bigint nullable / vat_rate text nullable).
+  - Adaptación: el `INSERT` usa `INSERT INTO orders_orders (source) VALUES ('pos')` en lugar de `DEFAULT VALUES` porque el CHECK de 047 (`source='pos' OR user_id IS NOT NULL`) rechaza una fila 100% NULL; `store_id`/`shipping_cents` siguen backfilliándose por el column DEFAULT → el intento de AC1/AC2 se verifica.
+
+## Verification
+- Migration 048 applies clean (dev + test DB): `node-pg-migrate up --verbose` → "Migrations complete!"; `048_reporting_store_shipping_snapshots (UP)` log; columns/FK/index presentes en `mercadodevida` dev. (Raw psql confirmó el DO-block FK válido en PG16.15.)
+- `TEST_DATABASE_URL=... npx vitest run src/app/tests/reporting-snapshots.itest.ts` → **3 passed**, 0 skipped, exit 0 (crea DB, migra 048, verifica todo).
+- `npx tsc --noEmit` → **0 errors** (incluye el itest .ts; estricto, noUncheckedIndexedAccess).
+- `node scripts/check-module-boundaries.mjs src` → **0 NEW violations** (única infracción R1 preexistente `security.routes.ts → log-broadcaster`, no introducida por F-144, fuera del diff).
+- `./scripts/verify.sh` → green (F-144 in_progress, runtime-consistent; 270 features válidos).
+- Re-run up() idempotente → no-op (DDL `IF NOT EXISTS` + DO guard); `down()` revierte todo.
