+Corrección mínima en `ReportingService.runSalesQuery`:
+
+1. `selectExpr` representa cuatro columnas dimensionales y debe terminar con coma antes de métricas agregadas.
+2. Para dimensión `terminal`, el resultado incluye tienda y terminal; ambas columnas deben estar en `GROUP BY`.
+3. Las expresiones dinámicas permanecen limitadas al enum `GroupBy`; filtros siguen parametrizados `$1..$8`.
+4. Verificación runtime autenticada de `day`, `channel`, `store` y `terminal` mediante proxy admin.

+# F-160 — Implementer
+
+## Fix
+- Añadida la coma ausente entre columnas dimensionales y agregados en `runSalesQuery`.
+- `groupBy=terminal` agrupa por `store_id, terminal_id` porque ambas columnas se seleccionan.
+- Añadidos 2 tests de regresión sobre SQL generado.
+
+## Evidencia
+- Reporting service: 16/16 tests PASS.
+- TypeScript PASS.
+- Runtime autenticado vía `:3004`: day=200, channel=200, store=200, terminal=200.
+- Filtros continúan parametrizados; dimensiones proceden de enum controlado.
