 ### Workflow Steps
 
 1. **Guard + metadata preparation** – the `Check if should proceed` and `Prepare metadata` steps compute the target tag, prerelease flag, whether the tag is the newest release, and a `safe_tag` slug used for branch names. When any rule fails, the workflow stops without touching the config.

+2. **Checkout source branches** – the default branch is checked out into `main/`, while the long-lived `x-files/app-upgrade-config` branch lives in `cs/`. All modifications happen in the latter directory.
 3. **Install toolchain** – Node.js 22, Corepack, and frozen Yarn dependencies are installed inside `main/`.
 4. **Run the update script** – `yarn tsx scripts/update-app-upgrade-config.ts --tag <tag> --config ../cs/app-upgrade-config.json --is-prerelease <flag>` updates the JSON in-place.  
    - The script normalizes the tag (e.g., strips `v` prefix), detects the release channel (`latest`, `rc`, `beta`), and loads segment rules from `config/app-upgrade-segments.json`.  
    - It validates that prerelease flags and semantic suffixes agree, enforces locked segments, builds mirror feed URLs, and performs release-availability checks (GitHub HEAD request for every channel; GitCode GET for latest channels, falling back to `https://releases.cherry-ai.com` when gitcode is delayed).  
    - After updating the relevant channel entry, the script rewrites the config with semver-sort order and a new `lastUpdated` timestamp.
-5. **Detect changes + create PR** – if `cs/app-upgrade-config.json` changed, the workflow opens a PR `chore/update-app-upgrade-config/<safe_tag>` against `cs-releases` with a commit message `🤖 chore: sync app-upgrade-config for <tag>`. Otherwise it logs that no update is required.

 ### Manual Trigger Guide
 
 1. Open the Cherry Studio repository on GitHub → **Actions** tab → select **Update App Upgrade Config**.
 2. Click **Run workflow**, choose the default branch (usually `main`), and fill in the `tag` input (e.g., `v2.1.0`).  
 3. Toggle `is_prerelease` only when the tag carries a prerelease suffix (`-beta`, `-rc`). Leave it unchecked for stable releases.

 You can run the same script locally via `yarn update:upgrade-config --tag v2.1.6 --config ../cs/app-upgrade-config.json` (add `--dry-run` to preview) to reproduce or debug whatever the workflow does. Passing `--skip-release-checks` along with `--dry-run` lets you bypass the release-page existence check (useful when the GitHub/GitCode pages aren’t published yet). Running without `--config` continues to update the copy in your current working directory (main branch) for documentation purposes.

 ### 工作流步骤

 3. **安装工具链**：安装 Node.js 22、启用 Corepack，并在 `main/` 目录执行 `yarn install --immutable`。
 4. **运行更新脚本**：执行 `yarn tsx scripts/update-app-upgrade-config.ts --tag <tag> --config ../cs/app-upgrade-config.json --is-prerelease <flag>`。  
    - 脚本会标准化 tag（去掉 `v` 前缀等）、识别渠道、加载 `config/app-upgrade-segments.json` 中的分段规则。  
    - 校验 prerelease 标志与语义后缀是否匹配、强制锁定的 segment 是否满足、生成镜像的下载地址，并检查 release 是否已经在 GitHub/GitCode 可用（latest 渠道在 GitCode 不可用时会回退到 `https://releases.cherry-ai.com`）。  
    - 更新对应的渠道配置后，脚本会按 semver 排序写回 JSON，并刷新 `lastUpdated`。
-5. **检测变更并创建 PR**：若 `cs/app-upgrade-config.json` 有变更，则创建 `chore/update-app-upgrade-config/<safe_tag>` 分支，提交信息为 `🤖 chore: sync app-upgrade-config for <tag>`，并向 `cs-releases` 提 PR；无变更则输出提示。

 ### 手动触发指南
 
 1. 进入 Cherry Studio 仓库的 GitHub **Actions** 页面，选择 **Update App Upgrade Config** 工作流。
 2. 点击 **Run workflow**，保持默认分支（通常为 `main`），填写 `tag`（如 `v2.1.0`）。  
 3. 只有在 tag 带 `-beta`/`-rc` 后缀时才勾选 `is_prerelease`，稳定版保持默认。  
-4. 启动运行并等待完成，随后到 `cs-releases` 分支的 PR 查看 `app-upgrade-config.json` 的变更并在验证后合并。
