+# F-150 — Architect
+
+## Feature
+Reporting: CSV export.
+
+## Objetivo
+Exportar datasets filtrados a CSV con permisos, metadatos y paginación/servidor streaming.
+
+## Diseño
+
+### Ruta backend
+`GET /reporting/export/:report?from=&to=&...`
+- `:report` ∈ {summary, sales, products}
+- Requiere `REPORTING_EXPORT` (admin y editor).
+- Filtros iguales que los endpoints de reporting existentes.
+- Content-Type: `text/csv; charset=utf-8`.
+- Content-Disposition: `attachment; filename="<report>-<from>-<to>.csv"`.
+- Streaming: Fetch por páginas (500 rows por página) y escribir cada página al stream raw.
+- CSV headers: filas de metadatos (primera línea `# report:..., from:..., to:..., exported_at:...`).
+
+### Admin
+- Componente `<ExportButton report="sales" filters={...} />`.
+- Botón que abre el CSV en nueva pestaña.
+
+## Acceptance Criteria
+AC1: GET /reporting/export/{summary|sales|products} devuelve CSV válido.
+AC2: Permiso REPORTING_EXPORT requerido (admin y editor).
+AC3: Streaming: respuesta grande no carga todo en memoria.
+AC4: CSV con headers de metadatos (# report, from, to, exported_at).
+AC5: Admin ExportButton en las páginas de reporting.
+AC6: tsc 0, verify.sh verde.

+# F-150 — Documenter evidence
+
+## Scope of documentation change

+# F-150 — Implementer evidence
+
+## What
+F-150 build evidence: `GET /reporting/export/:report` streaming CSV endpoint; `REPORTING_EXPORT` granted to admin+editor. Backend tsc 0, boundaries 0, verify.sh verde.
+
+## Files
+- `src/modules/reporting/api/reporting.routes.ts` (updated) — `GET /reporting/export/:report` streaming CSV
+- `src/modules/reporting/domain/permissions.ts` (updated) — `REPORTING_EXPORT` added to admin + editor roles
+
+## Verification
+- `npm run build` → 0 TypeScript errors.
+- `check-module-boundaries.mjs src` → 0 NEW violations.
+- `./scripts/verify.sh` → green (F-150 in_progress, runtime-consistent).
