fix(server): 按 S01–S10 评测修复读标抽取(F1–F8、口径 Q1–Q4)
- 合并时待确认条目不再借正式条目进清单,没通过的类别记在 pending_categories - 结构识别:章(按章跳过不相干的部分)、表后「上述……否则无效」说明、★ 节标题 - INVALID 补写法;输出用到上限 92% 按截断处理,拆到底时采用已有输出 - 格式范本正文、整表概括句不收;项目信息多看评标方法所在分块 - WPS 旧版 DOC 直接修正字体表字符集;表格按单元格切句(s3-v4) - 口径:★ 节继承实质性、★ 定义为计分项时降为重要、「必须/应」声明记 keyword 规则、 政府采购资格条件按 87 号令第六十三条带无效类别 - 提示词 substantive v5,qualification / schedule / tech_param v4 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
