-## 1. 安装前检查
+## 1. 推荐：二进制安装（无需 Node）

-**原则**：先执行检查；若 **Node / 包管理器 / 网络** 任一不满足下文要求，Agent 应 **在本机终端内主动完成安装或配置**（例如升级 Node、切换镜像、配置 `npm` 代理等），再继续 `bailian-cli` 安装。仅在无权限或环境无法自动化时，再向用户说明原因并请其配合。
+```bash

-1. **Node.js**
-   - 要求 **≥ 18.17.0**，执行 `node -v` 确认。
-   - 未安装或版本不足：由 Agent 自行安装或升级 Node。
+可选：正式安装读 CDN 上的 `manifest.json`。预发 / channel 验证一律读 `sync-release.json`（bailian-cli 的 channel 发版都会覆盖它）：

-2. **npm**（**唯一**允许的包管理器）
-   - 执行 `npm -v` 确认可用。
-   - 未安装或不可用：由 Agent **安装或修复 npm**（不要改用 pnpm/yarn 装 `bailian-cli`），再执行 `npm install -g bailian-cli`。
-   - 即使本机已安装 `pnpm`、`yarn` 等，**也仅用于其它项目**；装 `bailian-cli` 时仍必须用 `npm`。
+```bash
+curl -fsSL https://bailian.aliyun.com/cli/install.sh | bash -s -- --channel sync-release

 ### 推荐：浏览器登录（控制台会话）

-适用于本机交互式安装，无需用户手动复制 API Key：
-
 1. 执行 `bl auth status --output json`，判断是否已配置。
-2. 若未配置，在**用户本机终端**执行 `bl auth login --console`；命令会拉起浏览器完成阿里云控制台登录授权。

-3. 用户提供了 Key 之后，在**用户本机终端**执行（Agent 用终端工具跑，勿把 Key 写进回复正文）：`bl auth login --api-key <用户提供的_Key>`
-4. 登录成功后执行 `bl auth status --output json` 确认；汇报时只使用 masked 字段，**禁止**回显完整 Key。
-
-### 备选二：使用 Token Plan API Key
-
- 获取入口：[Token Plan 订阅详情](https://bailian.console.aliyun.com/cn-beijing?tab=plan#/efm/subscription/overview)
-
-1. 请用户从订阅详情页获取或复制 Token Plan API Key，勿要求用户发到公开渠道。
-2. 在用户本机终端执行：`bl auth login --config token-plan --api-key <用户提供的_Key>`。
-3. `token-plan` Profile 已内置默认 Base URL；登录命令会先测试 Key，通过后才保存并激活该 Profile，无需另行配置或重复测试。
-4. 执行 `bl auth status --config token-plan --output json` 确认；汇报时只使用 masked 字段。
-
-### 其他方式
-
- **环境变量**（不落盘到配置文件）：在 shell 中配置 API Key 环境变量；变量名见 `bl auth status --help`，勿在对话中向用户解释底层命名。
- **写入配置文件**（持久化，与 `auth login` 落盘相同）：`bl config set --key api_key --value <key>`（`--key api-key` 亦可）。**不会**像 `bl auth login --api-key` 那样先校验 Key 是否可用；Agent 引导安装时仍**优先**用 `auth login`。
- **命令行临时传入**：需要 API Key 的 `bl` 子命令可在**当次**执行附加全局 `--api-key <key>`，仅本次生效、不落盘（例：`bl text chat --api-key sk-xxx --message "你好"`）。与上文持久化方式不是同一用途。

 ## 4. 配置验证

-API Key 登录命令本身已经完成可用性测试，通过后只需确认配置状态：
-
 ```bash
 bl auth status --output json
 ```

-无需再执行重复的模型调用测试。若登录失败，根据 stderr / JSON 中的 `hint` 或 `message` 排查（网络、Key 无效、`base_url` 等）。DashScope 端点：使用 `--base-url` / `bl config set --key base_url` / `DASHSCOPE_BASE_URL`，默认中国大陆 `https://dashscope.aliyuncs.com`。

+ * Flow:
+ *   - Every mode uploads its assets to `<prefix>/<tag>/<basename>`; channel
+ *     mode also uploads `sync-release.json` to the prefix root (empty tag).
+ *   - After upload, every object is HEAD-verified against the local byte size
+ *     (reconciliation — the runner has the ground-truth artifacts on disk).
+ *   - Stable only: when the tag is a NEWER version than the current manifest
+ *     (compareVersions), rewrite `<prefix>/manifest.json` and the rolling
+ *     `<prefix>/latest.json` — both carry the SAME rolling-manifest body
+ *     written by binary-build.mjs. Channel mode never touches those two files.
+ *
+ * Zero-dependency: OSS V1 header signature (HMAC-SHA1) over plain fetch.
+ *
+ * Gating / failure model:
+ *   - BAILIAN_OSS_AK / BAILIAN_OSS_SK unset → warn + no-op (npm/GitHub publish
+ *     still succeed; set the secrets to enable the OSS channel).
+ *   - Once enabled, any upload/reconcile/manifest failure THROWS and fails the
+ *     release step — re-running the workflow is idempotent (uploads overwrite).
+ *
+ * Environment variables (all injected from GitHub repo Settings → Secrets;
+ * no OSS defaults are hardcoded in this repo):
+ *   BAILIAN_OSS_AK / BAILIAN_OSS_SK —— RAM AccessKey; needs oss:PutObject and
+ *                                      oss:GetObject on the release prefix
