 ### 8.0 范围：这一节先固定协议和要求，extension 本身先不做
 
 - **web ssh、文件、抓包等 extension 现在都不实现**，Agent 和 Probe 一样（Probe 是节点，同样要在本地执行下面的要求）。这里只把「谁来强制」和「怎么证明」定下来，以后实现时不改信任链，也不用重装节点。
-- **已经固定在节点本地的字段**：`controllers`（允许授权本节点 extension 会话的 passkey 凭证 id，必须是操作员集合里的凭证）由安装命令带来，节点注册时保存在 `trust.json`，Backend 之后改不了；从集合里去掉的凭证不再有效。**每个 Agent 和 Probe 都必须有属主，至少一把**：属主是节点敏感内容（extension 会话、加密数据）绑定的人——这些内容只有属主的 passkey 能授权、解密，没有属主的节点没有人能用它的敏感能力，也就不该存在。接收者名单（`recipients`）等做加密时再加。节点还没有 extension，所以现在只是被固定和保存，不起别的作用。

 ### 8.1 添加节点时选属主
 
-- API：`POST /api/admin/join-tokens` 的 `controllers: [credential_id…]`：不给就是操作员集合里的全部凭证；给了就必须非空，且每个 id 都是操作员集合里的凭证。**还没有建立信任根、或者一把属主都没有，都不能创建加入码**（400，字段 `controllers`）。`MoShiro__RequireOwner=false` 可以关掉（只给没有信任根的老部署）。
+- API：`POST /api/admin/join-tokens` 的 `controllers: [credential_id…]`：不给就是操作员集合里的全部凭证；给了就必须非空，且每个 id 都是操作员集合里的凭证。还没有建立信任根、或者一把属主都没有时，面板**提前拒绝**创建加入码（400，字段 `controllers`）——这只是尽早失败，免得装出一个起不来的节点；真正的强制在节点（上面）。`MoShiro__RequireOwner=false` 可以关掉这个提前检查（只给没有信任根的老部署）。
+- **逆推出绑定关系**：节点握手时把本地固定的属主（passkey 凭证 id）报给面板（hello 的 `owners`），面板顺着凭证 id 反查出它绑定在**哪个账户的哪把 passkey** 上，显示在「系统 → 版本」的「属主」列（对不上任何已注册 passkey 的显示「未知凭证」）。上报只是自述，真正的授权由节点自己校验 passkey 签名；以后给节点更多的接口和操作（extension 会话、加密内容）时，据此决定谁有资格用，不会越权到别人的节点。
 - 界面：「添加 Agent / Probe」对话框里一个「属主（passkey）」多选列表，**必选**（一把都不选时创建按钮不可用）；只是选，不用触碰。选定的写进安装命令，节点装上时固定。
 - 安装端也强制：`install.sh`、`install.ps1`、容器入口缺了 `MOSHIRO_GENESIS` 或 `MOSHIRO_CONTROLLERS` 就不装（只有没有信任根的老面板才用 `MOSHIRO_ALLOW_NO_OWNER=1`）；`fleet-enroll --genesis` 不带 `--controllers` 也拒绝。
 - 设计意图（还没做）：属主的 passkey 是敏感内容的钥匙。节点和 Probe 这一侧要在宿主侧拿到属主 passkey 的证明，才可以解密、才可以开 extension 会话；Backend 在这里只是搬运，见第 8.2、8.4 节。
