+# 检查点：总控 L-UPLINK 完成（ready-to-merge）
+
+## 线 / 任务
+- 线：总控 L
+- 任务：HandleUplink 分发到 message/identity/presence/group
+- 分支：`feat/l-uplink`（已推送 origin，未推 main）
+- 工作树：`e:\\code\\NixMsg-wt\\uplink`
+- 提交：`b8569b0` feat: 接线上行帧分发到 message/identity/presence/group
+- 基线：`origin/main` = `0efcfbb`
+
+## 完成内容
+- `appUplink.HandleUplink` 分发：send/ack/receipt_ack/recall/status、unlock、self.get/update/talk_password/login_password、presence.get/watch、directory.list、group.create/add/remove/leave/transfer/rename/dissolve/list/get
+- Session 仍处理 hello/logout 与未握手 not_ready；结果经 PublishDown 回 resp
+- `presence.EncodeGetData` 薄封装；serve 注入 identity/group/presence + Downlink
+- DEVIATIONS「总控 L」增补 L-UPLINK 节，保留其他节；未改 PRD
+
+## 验证
+- `task check`：通过
+- 集成测 `TestUplinkDMOfflineGroupRecall`：单聊、离线 keep、群发不含发送者、延迟内撤回对方无回调
+
+## 仍没接上的帧 / 未覆盖
+- 上行不处理（非请求或由 Session/下行服务发）：hello、self.logout、msg、receipt、revoked、presence 通知、group_event、fatal、resp
+- A3 管理注册设置 HTTP 未挂
+- presence.watch 通知与全部 group.* 变体未在集成测穷尽
+
+## 给下个会话
+- 总控可审阅后 ff-only 合并 `feat/l-uplink`
+- 勿强推 main
