+WBS_ID: V13-FE-011
+Date: 2026-08-09 (Asia/Seoul)
+
+Source:
+Browser inspection of /internal/ui-standard showed AG Grid's "No Rows To Show"
+overlay while the T01 catalogue rows were visible.
+
+Change:
+AgGridAdapter suppresses the no-rows overlay whenever the supplied row collection is non-empty.
+
+Commands and results:
+- pnpm test -- --run src/shared/ui/adapter/primevue/tests/AgGridAdapter.spec.ts
+  Test Files 1 passed (1); Tests 2 passed (2); exit 0.
+- pnpm typecheck
+  vue-tsc --noEmit; exit 0.
+- Playwright open/snapshot http://127.0.0.1:5173/internal/ui-standard
+  T01 rows remained visible and the stale "No Rows To Show" text was absent.
+
+Boundary:
+This evidence covers the shared-grid overlay only. It does not claim full component-catalogue, visual-baseline, accessibility, or MVP-A acceptance.
