+- shared 直连健康检查：10/10 HTTP 200；总耗时 p75 0.24 秒。
+- 本机系统代理开启；代理路径曾出现约 5 秒的 URLError，没有取得服务端 HTTP 状态。不能据此宣称服务器又返回 503。绕过代理的页面仍慢，代理不是全部原因。

+# 维护恢复后的性能诊断与优化方案
+
+日期：2026-11-14。状态：**诊断与方案，不包含上线批准。没有部署代码或修改生产配置。**
+
+## 测量口径与证据边界
+
+- 真实老师、学生会话，各覆盖首页与当天课表；一页一页访问，没有并发压测，没有操作开课、结课、取消预约、充值或扣费。
+- Chrome，390×844，Asia/Shanghai；每次新浏览器上下文，冷缓存，Fast 4G（增加 20ms 延迟、4Mbps 下行、3Mbps 上行），CPU 不限速。数字包含实际线路延迟，不等同于真实学生手机的 RUM。
+- “可用”要求关键统计、列表和刷新按钮加载完成，没有对应错误状态，统计/条数稳定 500ms；不以页面外壳或标题出现为终点。该 500ms 稳定窗口包含在报告耗时内。
+- 四种页面各十次，交替测量。先测系统默认代理路径，再绕过系统代理复测；两组不能当成优化前后 A/B，也不能将差额全部归因于代理，因为测量时段不同。
+- 分位数使用 nearest-rank：排序后第 ceil(n×p) 个值；n=10 时 p95 是该组最大值。失败单独统计，不作为快速样本。
+- 页面使用现有业务接口；学生复习的既有读取接口自身会执行旧系统同步，本次没有改写这一行为。未新增诊断云函数或修改公共服务。
+- 只覆盖两个账号的代表性页面。未进行全体账号、真实低端手机、课堂切词/语音、后台所有模块或高并发验收；不能据此宣布全系统性能已经达标。
+
+具体测量数值和脱敏原始样本见本目录 BASELINE.md、baseline.json。账号、token、接口原文保存在本机私有诊断目录，不入 Git。
+
+## 已证实的链路问题
+
+1. **学生首页复习读取依赖旧系统同步完成。** 回读当前生产网关，`appReviewPage` 先 `await syncLegacyReviews`，然后才能启动本地复习列表/统计查询。`performLegacyReviewSync` 先拉旧系统第一页 500 条，缺数时可继续拉页；单次旧接口请求的超时上限是 12 秒。随后 `applyLegacyReviewRecords` 开启事务、获取学员 advisory lock、比对记录并按需补写。即使已有记录，也需要完成旧系统请求及比对。这条依赖关系已确认，但本轮没有插入服务端计时，不能将接口总耗时全部算作旧系统网络等待。
+2. **一个页面读取会触发多项数据库汇总和版本查询。** 复习接口包含 summary、count、rows、可选 dates/students/income，以及 review/account 版本；学生端默认还取日期元数据。教师“今天”请求的列表限定今天，但汇总基于过滤今天之前的范围；每页又重复计算汇总/版本。课表也读取日期汇总、人员选项、总数、列表和版本。SQL 次数和范围是确定的优化对象，哪条 SQL 最慢仍需执行计划及阶段计时。
+3. **浏览器加载有固定成本，但不是多秒接口波动的充分解释。** 冷启动资源下载、路由模块加载在业务接口前；应优化首屏资源，同时避免把服务等待误判成动画或 CSS 问题。
+
+直连复测还捕获了学生复习的 `legacyReviewSync.state=unavailable`，以及多次 `conflict`（同一测试学生拉取 60 条、冲突 3 条、写入 0 条）。这是现有来源保护机制的结果，不能为了提速强行覆盖或删除冲突。当前学生首页没有展示该同步状态；因此“页面已显示已有数据”和“旧系统数据同步成功”必须分别计数、分别提示。应给冲突生成可核对的处理记录，避免每次打开首页都重复等待同一批比对。
+
+生产网关仍包含今早的运行环境兼容标记 `XIAOSHU_ISOLATED_RUNTIME_COMPAT_V1`，两条网关的 updatedAt 为 2026-11-14T00:38:27.640Z。本轮没有发现兼容补丁被覆盖。
+
+## 必须继续核实的运行环境因素
+
+今早事故记录曾捕获业务连接池 max=2、连接超时 5 秒，以及实际连接获取超时；这属于**维护完成前的证据**，不是现在的配置结论。维护方需要提供恢复后的：
+
+- 小树租户所在实例/worker 数量、重启与冷启动时间线，入口 upstream connect/header/response time；同一请求的 request ID。
+- 各实例数据库池 max、active/idle/waiting、获取连接耗时、超时数；数据库总连接预算、慢查询、锁等待和资源利用率。
+- 旧系统请求耗时，以及云函数中认证、旧系统同步、连接获取、SQL、序列化各阶段耗时。
+- 当前函数执行器是否每次请求重新创建函数作用域。今早 worker 快照使用 `new Function(...code...)`；若仍如此，网关顶层 Map 的 10 秒缓存不能可靠跨请求复用。当前运行语义需维护方确认。
+
+不要直接把连接池从 2 大幅调高。先核算“实例数×每实例连接数”的总预算，确认等待来自连接获取还是慢 SQL/锁，再小范围验证。不得改动其他租户服务。
+
+## 优化顺序
+
+| 优先级 | 工作 | 具体方案 | 正确性与验证 |
+|---|---|---|---|
+| P0 | 恢复后的稳定性与定位 | 维护方补齐上述阶段计时和连接池指标，区分入口、worker、数据库与旧系统 | 先消除连接超时/503；任何配置调整单独评审、回滚，不以健康检查 200 代替业务恢复 |
+| P1 | 学生复习读写解耦 | 首屏先读小树已同步数据；旧系统增量同步由有租约的任务承接，合并同一学员的同步请求并限制并发；新增可见的更新时间/同步状态 | 不能悄悄显示陈旧结果；完成复习、开结课、取消预约等写入以服务端最新状态核验，保留来源保护、冲突记录、事务和幂等键。未同步的新数据有明确状态与补偿重试 |
+| P1 | 减少查询数量及扫描范围 | 首页专用轻量读模型；今日任务统计按正确口径计算，分页后续页复用同一版本的统计；日期/人员元数据按需；合并 count/summary 或复用查询结果；版本查询改为可失效的轻量版本记录 | 先在隔离数据跑 EXPLAIN (ANALYZE, BUFFERS) 和结果对照，再决定索引；不得盲加索引或删掉学生需要的逾期/未来统计。验证任务总数、顺序、日期边界、收入与账本一致 |
+| P1 | 降低突发请求压力 | 按租户/接口限制数据库并发，合并相同读取；确认缓存生命周期并采用有界缓存；轮询增加抖动、隐藏页暂停、恢复事件合并、故障退避 | 保留跨设备排课更新；写入后精确失效；重试有总预算。已有首页缓存、隐藏暂停、并发限制不能当作本次新增成果 |
+| P2 | 冷启动与页面响应 | 分析首屏 bundle，延后非首页模块；优化 logo 等静态资源；检查版本化资源缓存；各面板独立可用，返回页面先展示明确标注的已有数据再校验 | 使用同一 ready 条件；不把旧数据冒充新数据，不隐藏接口错误；不通过延长超时或只改提示文案冒充提速 |
+
+## 验证与发布门槛
+
+1. 先在本地/隔离环境实施候选，一次只验证一个主要机制；同数据、同网络、同设备交替 A/B、B/A，每组至少 10 次，同时记录 p50/p75/p95、失败率、API 次数、SQL 次数、连接等待与长任务。
+2. 初步目标：核心四页面 Fast 4G 冷启动 p75 ≤3秒、p95 ≤5秒，热返回 p75 ≤1秒；关键轻量 API p75 ≤800ms、p95 ≤2秒。这是候选验收目标，**不是已达到或保证的收益**。数据新鲜度与跨设备一致性另设指标，不能用无限缓存换速度。
+3. 回归已授权真实身份的只读页面；隔离环境验证开课、结课、重复提交、预约取消、旧系统同步冲突、课时预留/释放、来源流水，保证没有重复扣课时或教师收入变化。
+4. 扩展到后台登录后加载、会员搜索、排课及批量操作结果核对，并补充多教师/多学生、低端手机、正常教学负载；不在生产做无边界压测。
+5. **等用户明确通知上线后**，再备份当前函数/静态版本、选择性发布、分批回读和业务验收；发现错误率上升、账务差异或 p95 退化立即回滚本批。当前只保存诊断与方案。
