/**
|
|||
|
|
* **服务器实例的覆盖网络设备凭据**：平台侧代签 ＋ 投递到实例 home ＋ 续签（序47 · S4/S5）。
|
|||
|
|
*
|
|||
|
|
* ## 为什么必须是"平台侧代签"
|
|||
|
|
* 本版平台**不存在**「实例 → 平台」的身份通道（交接单序47 §②.1 取证，⛔ 不许改判）：
|
|||
|
|
* `requireAuth` 只认 `sid` cookie、`POST /api/auth/login` 只收 `username + password`
|
|||
|
|
* （而平台不存明文口令、也从不把口令投给实例）、实例启动时平台投递的 env 里没有任何平台身份凭据。
|
|||
|
|
* ⇒ 实例**不可能**自己去调那份"用户态签发端点"，只能由**控制面以 `userId` 归属为据代签**。
|
|||
|
|
* 签发本身走的是**唯一实现** `device-grant.ts#issueDeviceGrant`（⛔ 本文件不复制那段判据）。
|
|||
|
|
*
|
|||
|
|
* ## 三件事，各自只有一处
|
|||
|
|
* | 关注点 | 落点 |
|
|||
|
|
* |---|---|
|
|||
|
|
* | 怎么签、按什么顺序落四处、失败怎么具名 | `device-grant.ts#issueDeviceGrant`（序47 S4 已抽） |
|
|||
|
|
* | **何时**签 / 何时续签 / 凭据文件长什么样 | 本文件 |
|
|||
|
|
* | 何时触发（实例启动 / 定时续签） | `supervisor/orchestrator.ts` · `remote-spawner.ts` · `web/server.ts` |
|
|||
|
|
*
|
|||
|
|
* ## 🔴 五条硬纪律
|
|||
|
|
* ① **写实例 home 一律走 `UserFs`** —— 实例可能在 worker 上，直接 `fs` = **静默空操作**
|
|||
|
|
* （档案 138 §五：读回空串、不报错）。本文件**不 import `node:fs` 写用户卷**。
|
|||
|
|
* ② **密钥不落平台**：私钥由平台生成后**只写进实例 home**（§④ 决策 6），平台不留副本、
|
|||
|
|
* ⛔ 不进日志、⛔ 不进审计 detail；⛔ **绝不**走 `home-files.ts#backupHomeFile`
|
|||
|
|
* ——那会把私钥复制进平台备份目录，等于自建一份副本。
|
|||
|
|
* ③ **⛔ 不改判、不重建**：凭据文件存在但形状非法 ⇒ **具名拒绝**（`credential-file-corrupt`），
|
|||
|
|
* ⛔ 不"修一下再看"。原因：重建必然生成新密钥对 ⇒ **hostId 改变**（`d-<uid>-<公钥前8位>`）
|
|||
|
|
* ⇒ 换一台"设备"，会绕过针对旧 hostId 的停发（`status='revoked'`）并多占一个配额位。
|
|||
|
|
* 处置 = 人工确认后**删除该文件**，下一次触发即重新签发。
|
|||
|
|
* ④ **续签复用同一把 nodeKey**（读回文件里的私钥）⇒ hostId 不变 ⇒ 台账那一行是**同一条**
|
|||
|
|
* （`grant_renewals + 1`），⛔ 不产生"第二条实例设备"。
|
|||
|
|
* ⑤ **每用户至多一条活跃的 `kind='instance'` 设备** —— 平台本来就"一账号一个 main 实例"。
|
|||
|
|
* 因此新签发（换 hostId）时，把该用户名下**其它** `kind='instance'` 条目**收编**：
|
|||
|
|
* 台账置 `revoked` ＋ 从 registry 移除。⛔ 这不是"顺手多做"，而是 ②③ 的直接补偿：
|
|||
|
|
* 没有它，"删文件重建"这条**我们自己写进回滚/处置流程**的动作会静默烧掉配额位，
|
|||
|
|
* 并在用户网里永久留一台查不到主人的已批准设备。
