-## 安装流程
+## 安装或更新流程
-### 1. 解析并固定最新 Commit
+### 1. 判断首次安装、更新或已有最新版
 先检查当前 MCP 客户端配置中的 `nocobase-crm` 条目、其启动命令和参数，以及推荐用户级安装目录中是否已有可执行文件。若存在 `<install-prefix>/install-receipt.json`，可以读取其中不含秘密的安装记录；只有 `schemaVersion=1`、仓库 URL 完全匹配、`commitSha` 为 40 位十六进制、`tarballSha256` 为 64 位十六进制且其余字段类型正确时才视为有效。无效或缺失的记录不能作为跳过构建的依据。不得打开、解析或输出凭证文件内容，只能在必要时判断凭证文件是否存在。
 按以下规则确定初始状态：
 - **首次安装：** 没有可用的 `nocobase-crm` 配置和已安装命令。默认只读，除非用户在本次任务中明确要求启用固定项目写入。
 - **更新：** 已有配置和可执行命令。沿用其安装前缀、CRM 配置路径及 `--enable-writes` 状态，除非用户明确要求变更；个人凭据始终原地保留。
 - **修复旧安装：** 只找到配置、命令或安装目录的一部分。说明检测到的不一致，然后按更新方式修复缺失部分，不删除仍可用的配置或凭据。
 记录检测结果、现有安装目录、当前版本、原读写模式，以及安装记录中的旧完整 Commit SHA（若存在）。旧版本没有安装记录不是错误，第一次更新时正常重建并补写记录。不得仅凭 npm 包版本判断 Commit 是否相同，因为多个 Commit 可以使用同一包版本。

+注册或重载完成后，**先调用 `crm_health`**。若返回 `ok=true`，说明现有登录仍然有效，直接完成验收；不得为了首次安装或更新流程的形式完整而调用登录工具、生成新链接或要求用户再次授权。
 只有 `crm_health` 明确返回 `nocobase_auth_failed` 时才进入登录：首次安装且没有可用凭据时调用 `nocobase_login({})`；更新/修复中已有凭据被 NocoBase 拒绝时调用 `nocobase_login({"force": true})`。如果 `crm_health` 返回 ACL、配置、网络或超时错误，处理对应错误，不能用重新登录掩盖它。

 - `user_code`：供用户在页面核对的确认码；
 - `expires_in_seconds`：剩余有效时间；
 - `browser_opened`：桌面浏览器是否已成功自动打开。

 - 尚未登录：让 Agent 调用 `nocobase_login`，把返回的 `login_url` 和 `user_code` 发给你；授权后调用 `nocobase_login_status`。

 - MCP 客户端暂时无法调用登录工具：可在本人终端运行安装程序的 `setup --no-browser`，这是备用入口。
 - 仅在 OAuth 暂时不可用且管理员明确要求时，才使用 `setup --manual-key` 的隐藏输入备用模式；不要把 Key 发到聊天中。
 - 返回 `NO_PERMISSIONS`：请检查本人 NocoBase 角色和数据权限。
