+## 2026-07-14 10:55 — DB死锁根治：盘中脚本统一get_conn()
+
+### 发现问题
+price_monitor.py的`refresh_data_prices()`已有完善的重试机制(5次+指数退避+WAL checkpoint)，但其他盘中高频脚本仍然使用raw `sqlite3.connect()`，绕过`get_conn()`的WAL模式+busy_timeout=30s设置。
+
+### 修改了什么
+- `mofin_health.py` — get_db_stats()改get_conn()
+- `cron_health_monitor.py` — price_monitor新鲜度查询改get_conn()
+- `intraday_health_check.py` — 3处sqlite3.connect全部改get_conn()
+- `self_todo_executor.py` — sqlite3.connect改get_conn()
+- `mofin_db.py` — get_conn()每次新建连接时WAL checkpoint
+
+### 测试结果
+并发压力测试：3x price_monitor + 3x mofin_health同时运行 → 6/6通过，WAL仅32bytes

+## 2026-07-14 10:55 — 知微XMPP Bot断线不重连修复
+
+### 发现问题
+自愈执行器发现知微XMPP Bot离线。调查发现：
+1. Bot进程(3643320)由gateway产生，但无任何TCP连接（断线后slixmpp不会自动重连，因为`auto_reconnect`默认关闭）
+2. systemd的xmpp-zhiwei.service有2276次失败重启记录（PID文件冲突）
+3. Bot进程(3643320)始于04:28，presence=unavailable，但HTTP桥(5805)仍活着
+
+### 根因
+slixmpp ClientXMPP的`auto_reconnect`属性默认为False。断线（connection_lost）发生后，bot进程保持运行（HTTP桥继续工作）但从不尝试重新连接XMPP。在main()中`await bot.ready.wait()`已通过，asyncio.gather继续运行，bot看起来活着但实际上无法接收/发送XMPP消息。
+
+### 修改了什么
+- `/home/hmo/xmpp_agent_core.py`:
+  1. AgentBot.__init__()加 `self.auto_reconnect = True`
+  2. 新增 `connection_watchdog()` 看门狗协程——每15秒检查连接状态，断线超过120秒执行`os._exit(1)`让gateway重新spawn
+  3. main()启动connection_watchdog作为独立任务
+
+### 执行了什么
+1. Kill旧bot(3643320) → gateway自动spawn新bot(114609) → 新bot连接XMPP成功但被ejabberd重启踢下线
+2. Kill中间bot(114609) → gateway再spawn(122594) → 稳定连接
+3. Kill 122594后gateway spawn新bot(131908)加载修复代码，自动重连生效
+4. Stop systemd xmpp-zhiwei.service（2276次失败重启，不再需要，由gateway管理bot）
+5. 清理PID文件 /tmp/xmpp_zhiwei_bot.pid
+
+### 效果预期
+- 断线后slixmpp自动重连（最快5s，指数退避）
+- 看门狗兜底：120秒未恢复则进程退出→gateway respawn
+- systemd不再干扰（已stop，gateway管理bot生命周期）
+
+### 文件
+- Modified: /home/hmo/xmpp_agent_core.py
+- Stopped: systemctl stop xmpp-zhiwei.service (2276失败重启)
