+### 业绩工具（2026-09-24 增补，`service/PerfTools.php`）
+
+线上发现“查业绩”很慢：模型为了排行逐部门、逐医助、逐天调用明细接口（一次问答 40 多次调用），还因为参数写法、未登记的子权限点和并发时的缓存读写失败而中断。业绩工具一次调用给出排名、合计和口径，并附带统计图：
+
+| 工具 | 数据来源（以调用账号身份执行后台原接口，口径与页面一致） | 权限（自身未登记时依次回退） |
+|---|---|---|
+| `zyt_perf_assistants` 医助业绩排行 | 业绩看板·医助排行榜 `YejiStatsLogic::assistantLeaderboards`：诊金、接诊诊单、接诊单数、预约诊单、被指派数、进线、接诊率；排名、合计、部门小计 | `stats.yejiStats/leaderboard` → `stats.yejiStats/tabLeaderboard` → `fans/yeji` |
+| `zyt_perf_doctors` 医生业绩排行 | 业绩看板·医生统计 `DoctorDailyStatsLogic::overview`：成交金额、接诊诊单、客单价、总挂号/完成/过号/取消、挂号率、系统/手动开方 | `stats.doctorDailyStats/overview` → `stats.yejiStats/tabDoctor` → `fans/yeji` |
+| `zyt_stats_performance` 部门业绩看板 | 业绩看板·甄养堂诊金 `YejiStatsLogic::overview`：各部门合计业绩、接诊诊单、接诊单数、预约、进线、被指派、投放成本、ROI | `stats.yejiStats/overview` → `stats.yejiStats/tabZyyt` → `fans/yeji` |
+| `zyt_perf_trend` 业绩走势 | 一条按日分组的只读聚合 SQL（在同样的只读事务里），按日/周/月归并，可对比最多 4 人。医助口径同排行榜诊金（订单创建人，剔除取消/拒收/退款）；医生口径同医生统计成交金额（开方医生，另剔除发生过退款的订单） | 按医助同医助排行，按医生同医生统计 |
+
+- 参数：`period`（today / yesterday / this_week / last_week / this_month / last_month / last_7_days / last_30_days，由服务器按当天计算）或 `start_date`/`end_date`；`dept` 可写部门名称（只在账号可见的部门里匹配）；`sort_by`、`top`、`name`/`*_id`；走势另有 `by`、`names`/`ids`、`granularity`、`metric`。
+- 数据范围：与后台一致（经理看本部门及下级、医助只看自己、医生统计只含可见医生）；走势指定的人必须在账号可见范围内。
+- 统计图：结果文字里带一个 ```` ```chart ```` 代码块（JSON：`type` bar/column/line、`title`、`subtitle`、`unit`、`labels`、`series`），行知把它画成统计图（可切换表格）；`structuredContent.chart` 同时提供。只有一行时不画图。
+- 权限回退（审核文件 `perm_fallback`）：子接口自身已登记时与后台完全一致；未登记时后台对该接口不校验、只靠 Tab/页面权限控制可见，这里改用第一个已登记的 Tab/页面权限，不会比后台页面更宽。同样的回退也加在了业绩看板的部门/渠道下拉和各明细子接口上。
+- 业绩看板、医生统计、提成结算、综合转化的单条 SQL 超时放宽到 30 秒（审核文件 `timeout`；后台控制器自己放宽到 120 秒）。
+- 同时修复：`params` 里写的 `page`/`page_size` 自动当作分页；限流与每日行数计数在缓存读写出错时放行并记日志（文件缓存下并发调用可能读到写了一半的文件，之前会让整次查询变成“内部错误”）；内部错误提示带上异常类型，便于对照服务器日志。
 - 授权接口：`POST /mcp/auth/grant`、`POST /mcp/auth/revoke`（Bearer）、`GET /mcp/auth/whoami`（Bearer），返回与后台一致的 `{code, show, msg, data}`；失败时 `data.reason` 为 `invalid_credentials / disabled / need_change_password / need_bind_wecom / no_ai_permission / locked / feature_disabled / ip_not_allowed / invalid_request`。

+ * 业绩快捷工具：医助排行、医生排行、部门业绩看板、业绩趋势。
+ *  - 一次调用给出排名、合计与口径说明，并附带行知可直接渲染的统计图（```chart 代码块）；
+ *  - 排行与看板以调用账号身份执行后台原有统计接口（业绩看板·医助排行榜 / 医生统计 / 甄养堂诊金），
+ *    口径、数据范围与后台页面一致，数字可直接和后台对账；
+ *  - 趋势用与排行榜相同口径的一条按日分组 SQL，在只读事务里执行，避免模型逐日、逐人循环调用明细接口。
+ *
+ * 图表格式（行知 RichText 渲染 ```chart 代码块）：
+ *   {"type":"bar|column|line","title":"…","subtitle":"…","unit":"元","labels":["…"],"series":[{"name":"…","data":[1,2]}],"note":"…"}
+ *   bar=横向条形（排行），column=竖向柱形（少量时间段），line=折线（趋势）；同一张图只放同一单位的数据。
