-```bash
-git tag v0.1.0
-git push origin v0.1.0
-# CI 自动打包并发布到 Gitea Package Registry（见 .github/workflows/publish.yml）
+Skill 的桌面端到端测试应通过宿主 IPC 获取**真实**当前用户数据目录，不要在 pytest 进程里手工设置 `JIANGCHANG_USER_ID` / `CLAW_USER_ID` 来伪造用户（否则会回退到 `_anon`）。
+
+推荐 preflight 流程：
+
+1. `require_logged_in_skill_data_dir(page, skill_slug)` — 经 `jiangchang:resolve-skill-data-dir` 解析路径，并断言已登录（非 `_anon` / `anon` / `anonymous`）。
+2. `assert_skill_env_file(ctx, ["API_KEY", ...])` — 检查 `{skill_data}/config/.env` 中必填项已配置且非占位符；E2E 不会自动生成真实密钥。
+3. `send_prompt_via_composer(page, prompt)` — 普通文本逐字键入；内容中的 `\n` / `\r\n` / `\r` 用 **Shift+Enter** 输入换行；最后用 **Enter** 发送（禁止 DOM 注入、剪贴板、JS 伪造 input/change）。
+
+诊断时可调用 `get_runtime_env(page)` 查看主进程解析的环境，**不要**用它拼用户数据路径。
+
+```python
+from jiangchang_desktop_sdk.e2e_helpers import (
+    assert_skill_env_file,
+    require_logged_in_skill_data_dir,
+    send_prompt_via_composer,

+## 共享媒体资源
+
+`jiangchang_skill_core.media_assets` 提供共享媒体资源解析能力。默认会从：
+
+`{JIANGCHANG_DATA_ROOT}/shared/media-assets`
+
+读取背景音乐、字体、水印和 ffmpeg 工具。
+
+如果目录不存在，会优先通过 ZIP 下载公开仓库：
+
+`https://git.jc2009.com/client-commons/media-assets/archive/main.zip`
+
+这不依赖用户电脑安装 Git。
+
+可通过环境变量覆盖：
+
+`MEDIA_ASSETS_ROOT=/path/to/custom/media-assets`
+
+### 录屏合成（`screencast`）
+
+`run_screencast()` / `compose_video()` 通过 `jiangchang_skill_core.media_assets` 解析 ffmpeg 与背景音乐，**不使用系统 PATH 中的 `ffmpeg`**。
+
+- **默认**：不传 `media_assets_root` 时，使用 `{JIANGCHANG_DATA_ROOT}/shared/media-assets`（或进程环境中已有的 `MEDIA_ASSETS_ROOT`）。
+- **覆盖**：传入 `media_assets_root="/path/to/media-assets"`，或在 `compose_video(..., media_assets_env={"MEDIA_ASSETS_ROOT": "..."})` 中设置；参数 `media_assets_root` 优先于 `media_assets_env` 里已有的 `MEDIA_ASSETS_ROOT`。
+- `run_screencast(media_assets_root=...)` 会把该路径原样传给 `compose_video()`；`music_subdir` 已废弃（会触发 `DeprecationWarning`），音乐选择统一由 `pick_background_music()` 完成。
+
+```python
+from screencast import run_screencast
+
+run_screencast(
+    skill_slug="demo-skill",
+    subtitle_script=[("PASSED", "测试通过")],
+    pytest_args=["-q", "tests/test_demo.py"],
+    output_dir="./out",
+    media_assets_root="/path/to/media-assets",  # 可选
+)
+```
+
+## 5. 发版流程（维护者）
+
+### main 分支自动预发布
+
+每次推送到 `main` 会触发 `.github/workflows/publish.yml`，自动构建并发布 **post 预发布版本**（仅供 CI 流水线内部使用，**不是**正式版本线）。
+
+正式版本线使用 **1.0.x** semver，通过 git tag 发布。
+
+```bash
+git push origin main
+```
+
+测试人员升级安装（始终安装当前正式 tag 对应的版本，例如 `1.0.9`）：
+
+```bash
+python -m pip install --upgrade \
+  --index-url https://git.jc2009.com/api/packages/client-jiangchang/pypi/simple/ \
+  --extra-index-url https://pypi.org/simple \
+  jiangchang-platform-kit
+```
+
+### 正式版本（tag）
+
+打 tag 并推送后，发布 **去掉 `v` 前缀** 的正式版本号（例如 `v1.0.9` → PyPI 包 `1.0.9`）：
+
+```bash
+git tag v1.0.9
+git push origin v1.0.9
+```
+
+### 安装后验证
+
+```bash
+python -c "from jiangchang_desktop_sdk.e2e_helpers import send_prompt_via_composer; print('e2e_helpers OK')"
+python -c "from screencast import run_screencast; print('screencast OK')"
+```
+
+仓库内还保留 `examples/`、`tools/`、`python-runtime/` 目录及既有 Skill / 前端相关的 GitHub Actions 工作流，与本 PyPI 包的发布彼此独立。`tools/screencast/` 为兼容薄壳，pip 包内实现位于 `screencast` 包（`src/screencast/`）。
+
+## v0.2.0 — data-jcid migration (internal refactor)
+
+### TL;DR
+
+本次内部重构:SDK 不再依赖匠厂主仓库的 `data-jcid` 属性。
+所有公开 API(`ask` / `read` / `new_task` / `wait_gateway_ready` 等)
+**签名与行为保持不变**,只有内部选择器实现切换到新的语义锚点 + ClawX testid。
+
+### 改变了什么
+
+- `client.py` 内所有 `[data-jcid="..."]` 选择器已移除
+- 改用匠厂主仓库为 SDK 承诺的语义锚点:`data-role` / `data-message-id` /
+  `data-streaming`(在 ChatMessage 上)、`data-sending` / `data-message-count`
+  (在 chat-page 根上)
+- `window.__jc_sending__` 仍是核心 sending 信号,保持不变
+- 这些锚点由匠厂主仓库的以下机制守护:
+  - `docs/JIANGCHANG_CUSTOM_ANCHORS.md` 中央清单
+  - 源码内 `JIANGCHANG CUSTOM ANCHOR` 边界注释
+  - `harness/specs/jiangchang-custom-anchors.spec.ts` E2E 守护测试
+  - Gitea CI grep 检查 step
+
+### 已知限制
+
+- `send_file()` 暂未实现,抛 `NotImplementedError`。
+  原因:附件上传走 Electron IPC,SDK 需要主仓库提供新 hook。
+- `_gateway_state()` 永远返回 `'unknown'`。
+  原因:gateway 状态不再暴露 DOM data-state;本方法已预留未来通过
+  `window.__jc_gateway_state__` 读取的实现路径。
+
+这两个限制对常规 ask/read 工作流**无影响**,sending 完成判定依靠
+`window.__jc_sending__` + `data-sending` + 文本稳定性合流即可。
+
+### 升级影响
+
+- 在 jiangchang v2.0.17(含)以上版本上跑:应正常工作
+- 在 jiangchang v2.0.16(及更早含 data-jcid 的版本)上跑:不再兼容
+  如果需要在旧版本上跑,固定 SDK 版本到 v0.1.x
+
+### 验证清单(集成方建议跑一次)
+
+打开匠厂客户端 → 用 SDK 跑下面 3 步,确认基础流程通:
+
+```python
+from jiangchang_desktop_sdk import JiangchangDesktopClient
+
+with JiangchangDesktopClient() as c:
+    c.ensure_app_running()
+    c.wait_gateway_ready()
+    c.new_task()
+    answer = c.ask("你好,请回复确认 SDK 可用")
+    assert answer, f"Empty answer: {answer!r}"
+    print("OK:", answer[:200])
+```

+## 4. 临时限制说明
+
+### send_file
+- 状态:抛 NotImplementedError
+- 原因:Electron IPC stage-paths,SDK 无 DOM 入口
+- 恢复条件:匠厂主仓库暴露 `window.__jc_stage_paths__` 或带 testid 的隐藏 input
+
+### _gateway_state
+- 状态:永远返回 'unknown'
+- 原因:HEAD 上 gateway 状态不暴露 DOM
+- 行为影响:_wait_for_streaming_done 中 `if gw not in ("running", "unknown")` 
+  实质 no-op,但保留以便未来生效
+- 恢复条件:匠厂在 main / store 暴露 `window.__jc_gateway_state__`

+
+- 是否运行了 platform-kit 自带的任何测试?
+  - [ ] 跑过 → 结果
+  - [x] 未跑 → 原因:本包无针对 desktop_sdk 的自动化集成测试;需实机 CDP
+
+## 7. 未触及的事项
+
+- `examples/`、`tools/screencast/`:未在本阶段验证;预期不直接依赖已移除的 data-jcid 选择器
+- platform-kit stash 中的 `runtime_env.py` 改动:本阶段未碰,仍在 stash(`stash@{0}: wip: claw env var fallback...`)
+- `D:\AI\jiangchang` 主仓库:未修改
+- 模块级 / 部分 helper / `ask()` docstring 中 data-jcid 历史措辞:保留,见 §9
+
+## 8. 自检
+
+- [x] grep 'data-jcid' 在可执行代码中 → 0 命中
+- [x] 公开 API 签名表逐项核对一致
+- [x] send_file 抛 NotImplementedError 而非静默
+- [x] _gateway_state 含 TODO 注释

+- [x] 未触碰 platform-kit 非 client.py / README.md / 本回执 的文件
+- [ ] git status 显示工作区干净(除本阶段预期修改 + 已有 stash) → 见 §1,未 commit
+
+## 9. 给验收方的备注
+
+1. **docstring 历史 data-jcid**: 模块顶 docstring(L10–L29)、`_last_user_node_index`(L526)、`_latest_assistant_after` 内联说明(L561)、`_chat_root_sending`(L610)、`ask()` docstring(L796) 仍描述旧 UI 模型;不影响运行。若需文档一致性,可单独开文档清理 PR。
+2. **send_file**: 调用即 `NotImplementedError`,无连接检查(按规格整段替换方法体)。
+3. **wait_gateway_ready**: 仅等待 `SEL_CHAT_PAGE` 可见,不保证 Gateway 进程已 ready。
+4. **建议验收**: 在已安装 v2.0.17+ 匠厂 + Playwright 环境跑 README 末尾脚本;并确认 `send_file(...)` 按预期抛错。
