 解读：开发构建成功；circular chunk 为仓库既有 Element Plus 分包警告，本次未改构建配置。

+## 2026-10-22 剧集转码面板组件拆分
+
+- 分支：`feature/transcode-panel-split`
+- 基线：`develop` / `origin/develop` = `52b10d3`
+- 计划：`docs/plans/2026-10-22-transcode-panel-split.md`
+
+已读取 `AGENTS.md` 与 `CODING_STANDARDS.md`。当前
+`EpisodeTranscodePanel.vue` 为 816 行，超过单文件 500 行红线。
+拆分将保持父组件的数据获取、轮询清理、分页请求与切集重置逻辑不变。
+
+### 拆分结果
+
+```text
+$ wc -l src/views/contentManagement/upload/EpisodeTranscodePanel.vue \
+  src/views/contentManagement/upload/EpisodeTranscodeStatusBadge.vue \
+  src/views/contentManagement/upload/EpisodeTranscodeStatusPanel.vue \
+  src/views/contentManagement/upload/EpisodeTranscodeRenditions.vue \
+  src/views/contentManagement/upload/EpisodeTranscodeFrames.vue \
+  src/views/contentManagement/upload/episodeTranscodeUi.ts
+266 EpisodeTranscodePanel.vue
+45 EpisodeTranscodeStatusBadge.vue
+155 EpisodeTranscodeStatusPanel.vue
+119 EpisodeTranscodeRenditions.vue
+315 EpisodeTranscodeFrames.vue
+93 episodeTranscodeUi.ts
+```
+
+解读：父面板只保留接口调用、轮询、请求序号、分页状态与组件组合；
+状态、清晰度、帧图分别独立，全部文件均低于 500 行。
+
+### 门禁
+
+```text
+$ pnpm ts:check
+> vue-tsc --noEmit --skipLibCheck
+（通过）
+
+$ pnpm lint:eslint
+> eslint --fix --ext .js,.ts,.vue ./src
+（0 error / 0 warning）
+
+$ pnpm build:dev
+ WARN  Circular chunk: element-plus -> vue-chunks -> element-plus.
+Build successful. Please see dist-dev directory
+```
+
+解读：组件 props/emits、类型检查、ESLint 和开发构建全部通过；
+循环 chunk 为项目既有警告。轮询启停、接口路径、分页参数和 locales 文案未改变。
