v2.3.0

Web：访问令牌 10 分钟；活跃时自动轮换刷新令牌；连续无操作 30 分钟后清除登录并跳转登录页。
App：会话窗口 3 天；打开 App、恢复前台或请求接口时自动刷新并重新顺延 3 天。
普通登录和 SSO 使用同一策略。
刷新令牌只以 SHA-256 摘要入库，每次刷新都会轮换，旧令牌无法再次使用；退出登录会吊销刷新令牌。
网络临时故障不会误清登录状态，多标签页同时刷新也做了竞争处理。

+启用、角色和学院数据范围仍以本系统 Identity 数据为准。首次 SSO 登录会用
+`preferred_username`（可通过 `Sso__UserNameClaim` 修改）优先匹配已有登录账号并记录

+
+数据库指标包括 `jiaowu.db.command.duration`、`jiaowu.db.command.slow` 和
+`jiaowu.db.command.failed`。为关键 EF 查询添加 `TagWith("模块.查询名")` 后，日志和
+追踪会直接显示该稳定名称；无标签查询只显示操作类型和 SQL 模板哈希。默认
+`Observability__IncludeSqlText=false`，不会把 SQL、参数值或连接串发送到日志和追踪
+系统。仅在受控诊断窗口内临时启用完整 SQL 模板，并限制 Collector 权限与保留时间。
+
+应用侧阈值用于关联接口、TraceId 和查询名称；生产 MySQL 还应由数据库管理员启用慢查询
+日志，并将 `long_query_time` 设为与应用阈值一致。先按查询哈希/标签汇总高频慢查询，再
+对脱敏后的 `SELECT` 在测试库或只读副本执行 `EXPLAIN ANALYZE`，根据实际扫描行数和循环
+次数决定是否补组合索引或改写投影。`EXPLAIN ANALYZE` 会真实执行语句，不能直接用于生产
+写操作。参考 [MySQL 慢查询日志](https://dev.mysql.com/doc/refman/8.0/en/slow-query-log.html)
+和 [MySQL 8.4 EXPLAIN](https://dev.mysql.com/doc/refman/8.4/en/explain.html)。
+
+OpenTelemetry Collector 将指标写入 Prometheus 后，超级管理员可直接在“组织与权限 →
+运维与审计 → 系统性能”查看请求量、5xx 比例、HTTP/数据库 P95、慢查询趋势，以及最慢
+接口和数据库查询排行。报表由 API 使用固定 PromQL 只读查询 Prometheus，浏览器不会
+接触 Prometheus 地址或令牌；结果默认缓存 30 秒。原始 Trace 和更长时间范围仍建议在
+Grafana 中下钻，配置其地址后页面会显示跳转入口。
