+`MediaAdapter` is the package's complete persistence boundary. Implement its asset queries, folder operations, uploads, updates, and deletes with the product's storage service.
+
+```ts
+import type { MediaAdapter } from "@workspace/media"
+
+export const mediaAdapter: MediaAdapter = {
+  listAssets: (query) => api.media.list(query),
+  listFolders: () => api.media.listFolders(),

+  updateFolder: (input) => api.media.updateFolder(input),

+  updateFavorite: (id, favorite) => api.media.favorite(id, favorite),
+  deleteAsset: (id) => api.media.delete(id),
+}
+```
+
+## Separate display and reference URLs {#separate-display-and-reference-urls}
+
+Use `resolveUrl` for short-lived signed URLs or image transformations used while rendering. Use `resolveReference` for the value returned by the picker and stored in another document. When `resolveReference` is absent, images use `defaultMediaReference`, which preserves intrinsic dimensions in the URL.
+
+## Preserve query semantics {#preserve-query-semantics}
+
+Treat `MediaAssetQuery` as an immutable request. Apply `allowedKinds`, `filter`, `folder`, and `keyword` before pagination, then return `hasNextPage` based on the filtered result. This keeps desktop and mobile filters consistent.

+
+## Package role {#package-role}
+
+`@workspace/media` provides reusable media-library and asset-picker surfaces. The host application supplies persistence through `MediaAdapter`; Media owns browsing, filtering, pagination, uploads, folders, selection, and asset actions.
+
+## Capabilities {#capabilities}
+
+- Browse images and videos with search, filters, folders, favorites, and pagination.
+- Upload to local or cloud storage targets exposed by the adapter.
+- Create, rename, nest, and delete organizational folders.
+- Select one or multiple assets through `MediaPickerDialog`.
+- Resolve display URLs and stable references independently.
+- Ship `en-US` and `zh-Hans` message catalogs.
+
+## Design boundary {#design-boundary}
+
+Media does not choose an API, database, object store, CDN, or signing strategy. The application implements those decisions behind `MediaAdapter` and can replace them without changing the interface components.
+
+> Folders classify assets inside the library. They do not need to mirror object-storage paths or change public URLs.

+
+## 区分展示与引用 URL {#separate-display-and-reference-urls}
+
+使用 `resolveUrl` 返回渲染时需要的短期签名 URL 或图片转换地址。使用 `resolveReference` 返回选择器写入其他文档的值。未提供 `resolveReference` 时，图片会使用 `defaultMediaReference`，在 URL 中保留固有尺寸。
+
+## 保持查询语义 {#preserve-query-semantics}
+
+将 `MediaAssetQuery` 当作不可变请求。在分页前依次应用 `allowedKinds`、`filter`、`folder` 和 `keyword`，然后根据筛选后的结果返回 `hasNextPage`。这样可以保持桌面端与移动端筛选行为一致。
