- 迁移 0022:problem_tag 加 category(knowledge / theme)和 category_confirmed; 存量 25 个题材、题集类标签归主题,其余归知识点,全部记为已确认 - 前台题目列表按两组显示标签,组内按题目数从多到少 - 后台标签管理:每行切换分类;出题时新建的标签默认知识点、标「待归类」并排在最前, 页头提示待归类数量,可点「确认」保留默认;加分类筛选 - 新接口 PUT /admin/problem-tags/:id/category,设置分类即视为确认 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
