 ### 7.1 高价值问题独立专区（2026-10-20）
 
-- 平台管理员独立发布问题、悬赏整数分金额及截止时间；工单关联可选，不建占位工单。独立问题公开为“平台发布”，关联问题为匿名提问人，答案题内匿名，发布人不默认获得提问奖。
+- 平台管理员独立发布问题、悬赏整数分金额及截止时间；工单关联可选，不建占位工单。独立问题公开为“平台发布”，关联问题为匿名提问人，发布人不默认获得提问奖。
+- 高价值问题取消回答者匿名机制：答案列表、最佳解答、管理员最佳回答选项和社区优选结果展示回答者用户显示名，优先 `name`、为空时回退 `username`、账号不存在时显示“未知用户”；历史答案同步适用。发布前提示展示用户名，草稿仍仅本人可见，问题相关身份及正文敏感信息继续保护，不改变点赞、奖励及实名人员榜规则。（2026-10-26调整）
 - 状态及结果管理仅允许原admin身份或全局“超级管理员/管理员”角色；服务端派生 `can_manage_knowledge_challenges`，前端不能通过普通内容审核/财务角色或按钮标记获得管理权。首页高价值问题卡片向全部登录用户展示，公开内容及参与接口仍要求有效登录；开放可见性不等于授予发布、状态变更或最终结果管理权限。
 - 到期无内容审核、无专家派审、无全量管理员确认；按有效答案赞降序、首次正式提交时间升序、答案ID升序选出唯一最佳，零赞同样排序。无已提交合规答案则结束且无解答奖，草稿不参评。
 - 题赞只决定问题榜热度；普通问题、关联同题、独立问题共用北京时间每日5题额度，取消不返额、跨入口不重复占额。答案另计每日5条，不得自赞；用户行锁序列化额度检查。
