+## 附录 C：创作壳编目/分页本库保存（2026-04-15）
+
+**背景**：乐读派 `PUT /update/work` 在部分远端环境下仅允许 status 3/4 编辑元数据，已配音（5）等场景会与「本库需保存编目/分页快照」冲突。
+
+**约定**：
+
+- **公众端创作壳**（`EditInfoView`、`DubbingView` 完成配音后）保存编目字段与分页（含各页 `audioUrl`）时，使用 **`PUT /api/public/leai-works/{remoteWorkId}/work-form`**，直写 `t_ugc_work` / `t_ugc_work_page`，**不经过** `PUT /leai-proxy/work/{id}`。
+- **鉴权**：当前登录用户须为 `t_ugc_work.user_id` 对应作品；`remote_work_id` 与路径参数一致。
+- **字段**：编目与 `updateWork` 请求体对齐（`author`、`title`、`subtitle`、`intro`、`tags`）；可选 `pageList`（乐读派 `pageList` 形态：`imageUrl`、`text`、`audioUrl` 等）。配音仍通过现有 **`/leai-proxy/voice`、`/leai-proxy/batch-audio`** 等与乐读派交互，仅**本库快照**走上述接口。
+- **状态**：编目写入成功且本地 `leai_status >= 3` 时，若发布状态仍为 `draft`，可升为 `unpublished`；`pageList` 中**每一页**均有非空 `audioUrl` 时，可将本地 `leai_status` 置为 `5`（DUBBED）。
+
+**与《企业同步创作数据 核心三步 V4.0》的关系**：
+
+- Webhook、`GET /leai-proxy/work/{id}`（B2）仍是**远端乐读派状态与 pageList** 的同步通道；本接口解决的是**本库元数据与分页快照**的权威写入，避免依赖乐读派 PUT 编目。
+- 远端状态前进仍以 V4.0 规则（`remote_status > local_status` 等）为准；本接口不改变 Webhook 语义，仅补充「创作壳保存」路径。
