+## 存储线复审修复 D-01/D-02/D-04/D-05 完成
+
+- **线**：存储/配置/命令行/部署
+- **分支**：feat/fix-store-d01-d05
+- **工作树**：E:/code/NixMsg-wt/r2-d（未改主工作区，未删 fix3）
+- **基于**：origin/main @ 4059a15
+- **提交**：b6908cf fix: 修复写队列 busy 恢复、关闭安全、备份与配置构建问题
+- **已推送**：origin/feat/fix-store-d01-d05（普通推送，未推 main、未强推、未 merge）
+
+### 完成
+- **D-01 (#27)**：runBatch 提交成功后 markReady，busy 后一次成功 Do 恢复 IsReady
+- **D-02 (#28)**：Close 在写锁内关 channel，并发 Do 不 panic；关闭后 ErrQueueClosed。新增 ExecOnWriter/Checkpoint/Optimize。未改 message 包，checkpoint 调用留给 C-03
+- **D-04 (#30)**：backup 库不存在报绝对路径错误、不建空库；chmod 0600；OPS 绝对路径 + 恢复须移走 db/wal/shm。未做 restore 命令
+- **D-05 (#31)**：迁移备份 pre-migrate-v{from}-to-v{to}.db 复用；Taskfile/q.yml/Dockerfile ldflags 注入 Version（K-05 为 SDK 打包，无冲突）；显式 grace_seconds:0 按 0 生效；max_frame_bytes<=786432；admin set-password 清空 admin_sessions。healthcheck 在 TLS 且不允许明文时走 HTTPS
+
+### 未做
+- **D-03 (#29)**：读连接池上限，依赖 C-01/C-02，按指示跳过。OpenReader 未改
+- 未改 cmd/nixmsg/serve.go 的 messageLoops，未改 broker/message/group/web/sdk/listener 业务
+
+### 验证
+- go test ./internal/store/ ./internal/config/ ./cmd/nixmsg/ -count=1 通过
+
+### 给下个会话
+- rebase origin/main 后由总控 ff-merge；勿在 e:/code/NixMsg 主工作区改
+- D-03 等 C-01/C-02 后再做
