+# 检查点：测试线 Q · T-01（issue #3）已推送，未合入 main
+
+## 线 / 任务
+- 线：测试交付 Q
+- 任务：T-01（Gitea #3）测试 WS 客户端拆包/写锁，去掉群事件 20ms 绕过
+- 分支：`feat/fix-t01-ws-harness`（已推送 origin，未推 main，未关闭 issue）
+- 提交：`14f93dcf7584acd766235053011344626b89af73` fix: 测试 WS 客户端按字节流拆包并恢复群事件同步下发
+- 工作树：`E:\code\NixMsg-wt\r2-t`
+- 基线：`origin/main` = `4059a15`
+
+## 完成内容
+- `test/harness/mqtt.go`：Recv 按 MQTT 字节流缓冲拆包（含 continuation）；Send/PONG 互斥锁且整帧一次 Write
+- 新增 `test/harness/mqtt_test.go`：合帧 3 包、跨帧3、双 goroutine 各 Send 1000 次
+- `internal/app/group/app.go` 仅 `emit`：去掉 goroutine+20ms，同步 PublishDown QoS0
+- F15：去掉独立短进程，同一长会话 `group.add` + 当次对话密码
+- `docs/DEVIATIONS.md`：标注 Q accept-rest 2–4 与「死锁未修」已被 T-01 取代，文末 `### 复审修复 T-01`
+- `test/accept/ACCEPTANCE.md`：更正误判死锁的结论
+- 未改 `internal/broker/`、`cmd/nixmsg/`、`sdk/`、`web/`、`internal/admin/`；未合入 `feat/fix-3-downlink-deadlock`；未删 `E:\code\NixMsg-wt\fix3`
+
+## 验证
+- `go test ./test/harness/ ./internal/app/group/ ./cmd/nixmsg/ -count=1` 通过
+- `go test ./cmd/nixmsg/ -run TestUplinkDMOfflineGroupRecall -count=20` 通过（79.7s）
+- `go test ./test/accept/ -count=1` 通过
+- `task check` 通过（web build、golangci-lint 0 issues、go test ./...）
+
+## 下一步
+- 总控审阅后 ff-only 合并 `feat/fix-t01-ws-harness`
+- 不修 T-02/T-03；不强推 main
+
+## 给下个会话
+- issue #3 仍 open，可在评论看 commit
+- 勿删 `E:\code\NixMsg-wt\fix3`
+- 本工作树 `r2-t` 可在合并后清理
