-> 「数据中心 / CGNAT / 境外 IP 高德返回空」的痛点，但**浏览器原生定位在非 localhost 的

 **Goal:** Add video upload/playback to special-folder photo walls, with asynchronous server-side ffmpeg compression for low-bandwidth playback.
 
+**Current status:** This is an implementation plan only. The current codebase does not yet include `Server/src/media.rs`, `/api/web/folder/{name}/media*`, `Client/src/api/folderMedia.ts`, or video rendering in `PhotoWallPage`.
+
 **Architecture:** Special folders move from photo-only endpoints to media endpoints. A new backend media module owns media ids, metadata files, multipart streaming, ffmpeg command construction, and one-at-a-time transcode coordination; `routes/web.rs` only exposes HTTP handlers. The React photo wall keeps personal `#photo` image behavior unchanged, while special folders use a new media API and render images, processing videos, ready videos, and failed videos in the same draggable wall.

-- [ ] **Step 5: Run backend tests**
+- [ ] **Step 5: Migrate shared wall state API to mediaLayout**
+
+The frontend task will save `mediaLayout`, but the current backend state model only accepts
+`photoLayout`. Update both `Server/src/folders.rs` and `Server/src/routes/web.rs` so the shared
+folder wall state supports the new key while preserving old saved state.
+
+Required behavior:
+- `PUT /api/web/folder/{name}/state` accepts either `mediaLayout` or old `photoLayout`.
+- `GET /api/web/folder/{name}/state` returns `mediaLayout`.
+- During one compatibility release, `GET` may also return `photoLayout` with the same value so older
+  frontend builds keep working.
+- Existing `wall-state.json` files that contain `photo_layout`/`photoLayout` must still load.
+
+Implementation direction:
+
+```rust
+#[derive(serde::Serialize, serde::Deserialize, Clone, Debug)]
+#[serde(rename_all = "camelCase")]
+pub struct WallState {
+    pub bg_index: usize,
+    pub decorations: Vec<Decoration>,
+    #[serde(default, alias = "photoLayout", alias = "photo_layout")]
+    pub media_layout: std::collections::HashMap<String, PhotoLayout>,
+    #[serde(default, skip_serializing_if = "std::collections::HashMap::is_empty")]
+    pub photo_layout: std::collections::HashMap<String, PhotoLayout>,
+}
+```
+
+When saving, normalize the layout once:
+
+```rust
+#[derive(Deserialize)]
+struct StateSaveRequest {
+    #[serde(rename = "bgIndex")]
+    bg_index: usize,
+    decorations: Vec<serde_json::Value>,
+    #[serde(rename = "mediaLayout")]
+    media_layout: Option<std::collections::HashMap<String, serde_json::Value>>,
+    #[serde(rename = "photoLayout")]
+    photo_layout: Option<std::collections::HashMap<String, serde_json::Value>>,
+}
+
+let layout_values = body
+    .media_layout
+    .or(body.photo_layout)
+    .unwrap_or_default();
+```
+
+Then save `media_layout` and, for the compatibility window, mirror it into `photo_layout`.
+
+Also add or update backend tests that deserialize:
