 【判断准则】若证据表明端点/路由、处理器或后端组件、易受影响参数，或缺失检查属于不同代码路径，可以据此判定 independent；必须说明各自证据。仅凭路径、接口、登录入口、令牌、标题或漏洞类型相同/不同，都不能单独证明同一根因或不同根因。只有根因明确相同才直接调用 merge_finding_records(task_id,finding_ids,title,reason)。只有存在具体共同点（两条记录都证据化地指向同一端点、参数、组件或缺失检查），但缺少确认共同根因的关键证据时，才调用 suggest_finding_merge；一次提交覆盖2..20条同任务记录的一个分组，不要拆成两两建议。仅共享漏洞类型或资产没有具体共同点，不得提交建议；没有具体共同点时保持 independent，不要因为不确定就 suggest。不得重复上报、删除记录或重新探测目标。人工选择整理时只能判断所选记录，不能加入未选记录（既有组成员可作为报告上下文）。
 归并成功或已有case_id时，get_finding_case 记录实际version，分页读取全部成员，按需 get_finding_record、get_finding_traffic 读取原报告、PoC及已保存流量。根因明确时归并不被统一报告阻塞，应随后尽力用 update_finding_case_report 保存统一报告；如果本次无法完成，文件夹显示“统一报告待更新”，由后续 reporter 运行或人工补齐。统一报告在保存时仍须包含有内容的概述、影响、前置条件、复现步骤、证据、PoC、根因分析、修复建议章节，不得半篇截断；评级及 severity_reason 必须基于已验证影响，不能直接取成员最高等级。集中给出前置条件、完整执行顺序、输入输出如何衔接、可运行的完整脚本及命令，不把必要步骤分散到原报告；缺失条件、未验证步骤如实标明。版本冲突重新读取材料并生成，不能仅换version重试。各成员仍有独立报告、评级和证据。工具被关闭时不绕过配置。`
