-SQLAlchemy Event Listener 审计监听器（单体架构版）
-监听器亲自完成入库，不依赖 g 对象，不依赖装饰器回调。
-只要模型发生 INSERT/UPDATE/DELETE，监听器直接创建 AuditLog 并挂载到当前事务 session。
+SQLAlchemy Event Listener 审计监听器（业务友好版）
+
+设计要点
+--------
+1. **白名单制**：只审计核心业务表（WHITELIST_TABLES），不做全局 db.Model 监听。
+2. **请求上下文守卫**：仅在 has_request_context() 为真时记录，杜绝系统初始化 /
+   后台定时任务产生的 `username=system` 噪声日志。
+3. **同事务写入**：使用事件回调给的 connection 直接 INSERT，随主事务提交/回滚，
+   不影响业务事务；写入失败仅记日志，不抛异常。
+4. **业务友好**：target_name 优先取业务标识（单号/SKU/物料编码），
+   兜底格式为「中文表名 - 业务号或ID」，不再出现 `stock_buy ID:468`。
+5. **安全**：密码/令牌类字段在 IGNORE_FIELDS 中，绝不落入 details。
+6. **时区**：created_at 显式写入北京时间（beijing_time），与全系统口径一致。
