 ## 后端补齐优先级
 
+## 和旧题库相比仍缺的明确功能
+
+这些是旧项目中已经出现过、但新后端还没有完整业务闭环的功能：
+
+1. 题目反馈：学生提交题目纠错、租户后台处理、状态流转、处理通知。
+2. 签到积分：每日签到、积分流水、连续签到、积分和活动/兑换的关系。
+3. 排行榜：刷题、模考、背单词排行榜，以及防刷、租户/地区/班级维度。
+4. 考试倒计时：`exam_dates` 表已有，但还缺学生端查询和后台维护 API。
+5. 订单状态轮询和激活码预检查：订单列表和兑换已有，但旧商城体验需要更细的状态查询/预检接口。
+6. 账号设置完整流：头像上传、绑定/更换手机号、微信/QQ 账号合并、密码/邮箱能力。
+7. 题库导出：PDF/Word/JSON 导出、水印、导出审计和权限控制。
+8. 导入扩展：Excel/CSV、分数线、视频批量导入和大批量异步 worker。
+9. 公共题库商业化：平台公共/地区题库披露、租户采纳、套餐授权、版本同步。
+10. CRM/销售结算：真实 CRM worker、轮询/定向分配、分佣规则、结算单、审核和导出。
+
 ### P0：前端联调到云端前
 
 1. 正式鉴权：API 已支持 Supabase Auth JWT；继续补真实云端 Auth/JWKS 回归、RLS 深测和自定义角色权限细化。

 # 多租户与鉴权安全契约
 
-更新时间：2026-06-28
+更新时间：2026-06-29
 
 这个系统后续要卖给同行作为题库 SaaS，因此租户隔离、鉴权、资源权限和审计是商用红线。前端可以先按迁移期接口联调，也可以按 Supabase 官方推荐使用 publishable key + RLS 的客户端能力管理 Auth/session，但正式上云验收前必须完成本文件的 P0 项。
