+1. **后台加人审计按实际插入数，全跳过不记 ok**  
    - 日期：2026-09-30  
-   - 原条款：Gitea #66；B-04 / B-08。  
-   - 实际做法：带断开的下行帧用本帧 `OnPacketSent` 完成信号（优先 packet id，否则按载荷匹配），不再用连接级 `sentPub` 总数。`Shutdown` 在 ctx 未取消时先等下行队列与 `wirePending` 排空，再 `DisconnectClient` 发 `0x8B` 并在截止前等连接拆掉；ctx 已取消则发完即 `Close`。`serve` 仍给 5 秒预算并记录非超时错误。未合 `feat/fix-3-downlink-deadlock`。  
-   - 原因：前面 PUBLISH 的 `OnPacketSent` 会让总数等待提前返回；`Shutdown` 对 ctx 非阻塞 select 使 5 秒预算用不上，有 outbound 积压时 `0x8B` 只进 outbuf 随 `Stop` 丢掉。  
-   - 备选方案：恢复固定 `Sleep`（否决）；改 `PublishDown` 签名（否决）。  
-   - 影响：队列/outbound 有积压时 fatal、logout 先到客户端再断开；停机在预算内尽量发出 `0x8B`，超时返回 ctx 错误而非空等。
+   - 原条款：Gitea #72；`AdminAddMembers` 对已是成员与请求内重复编号静默跳过；审计用 `len(member_ids)-len(failed)` 当成功数。  
+   - 实际做法：`handleGroupAddMembers` 用加人前后 `group_members` 行数差得到 `added`；审计 `result` 用 `added` 与 `failed`（全跳过且无失败记 `noop`，不记 `ok`）；响应增加 `added`，`failed` 仍只含真正失败项。前端按 `added` 提示，已是成员不改成错误码。  
+   - 原因：全是已有成员时旧逻辑审计成 ok、界面提示已加人，实际插入 0 行。  
+   - 备选方案：把已是成员写入 `failed`（否决，会改变客户端错误语义）；扩展 `group.AddResult` 返回插入列表（可后续做，本波不改身份线接口）。  
+   - 影响：管理 API 加人成功体多 `added` 字段；契约文档示例仍写 `{"failed":[]}`，以本偏差为准。
