 ## 登录恢复动作不得混用
 
+- `inspect-owner-ssh-login` 只回读 SSH 的有效密码认证、交互式认证和 root 登录策略，不读取密钥或密码。
+- `disable-owner-password-login` 关闭 SSH 密码认证与交互式认证，并把 root 登录限制为仅密钥；人格体仍只能通过主人批准的工单调用固定动作，不能取得任意 shell。
 - `restore-owner-password-login` 只恢复京东服务器的 SSH 密码认证开关；它不读取、不重置，也不验证光湖代码频道账号。
 - `restore-code-channel-owner-login` 只把京东本机旧第五域数据库中的 `bingshuo` 密码摘要恢复到新代码频道，同时校正启用、管理员和禁止登录状态。它不读取明文密码，不修改 SSH，并在变更前使用 SQLite backup API 生成一致性备份。
 - 登录问题先执行 `inspect-code-channel-owner-auth`。只有确认新旧频道凭证不一致时，才申请后一项恢复动作；不得绕到新加坡灾备节点，不得向冰朔索要密码。
