+
+status: done
+task: 建立 StorageWorker 烟测（原生 IndexedDB）
+
+## Evidence
+
+- Client: `web/app/src/storage/StorageClient.ts`
+- Worker: `web/app/src/workers/storage.worker.ts`
+- Backend: browser-native IndexedDB in a dedicated Worker
+- Screenshot: `tests/golden/W-014/storage-viewport-1440x900.png`
+
+The worker writes and reads a smoke record through IndexedDB and reports whether
+the Worker can also access OPFS. SQLite WASM is intentionally deferred because
+it is not required for the current project metadata and file workflow.
+
+## Verification
+
+```text
+npm run typecheck  # passed
+npm run lint       # passed
+npm run build      # passed
+npm run test:e2e   # Storage: IndexedDB (or IndexedDB + OPFS)
+```
