- status: `in_progress`
- gap: `workflow:module_storage_recovery`
- ownerFamily: `STORAGE`
- targetImplementationClass: `LOCAL_BOUNDED`

## 目标

按功能模块验证 IndexedDB catalog v1/v2 migration、page/Worker restart、OPFS preview commit/dedup、corrupt quarantine 和 final-reference GC。

## 输入与范围

- Protocol: `web/protocol/storage.ts`, `web/protocol/storage-budget.ts`, `web/protocol/save-transaction.ts`, `web/protocol/recent-projects.ts`, `web/protocol/asset-preview.ts`, `web/protocol/asset-preview-decode.ts`
- Storage implementation: `web/app/src/storage/asset-catalog-indexeddb.ts`, `web/app/src/storage/asset-preview-opfs-commit.ts`, `web/app/src/storage/asset-preview-quarantine.ts`, `web/app/src/storage/asset-preview-reference-gc.ts`, `web/app/src/storage/opfs-files.ts`, `web/app/src/storage/migrations.ts`, `web/app/src/workers/storage.worker.ts`, `web/app/src/app/App.tsx`

## 验收

```bash
npm --prefix web run test:asset-catalog-restart
npm --prefix web run test:asset-preview-dedup
npm --prefix web run test:asset-preview-quarantine
npm --prefix web run test:asset-preview-reference-gc
npm --prefix web run typecheck
```

必须记录 migration/restart 正例、partial/corrupt/non-final reference 负例、OPFS replay、quarantine cleanup、deterministic GC 和 Chromium。存储容量与浏览器能力限制保持显式 BLOCKED，不推导完整 Media I/O parity。
