"""报告末尾「分析范围」里的编号点得开（GET /runs/{id}/evidence/analyses/{alias}）：那份分析结论的出处链和点开正文里它的判定语
|
|
是同一条（api/evidence._scope_chain），正文没引用的结论（算不了的、可比性检查）也点得开；证据目录里没有的编号 404。
|
|
|
|
真运行、真算子：照 tests/test_analysis_e2e_claims.py 的虚构零售库 shop（数据目录标了地区、渠道是属性），Agent 查两次库、
|
|
做一次变化拆解、一次波动基线（两周历史不够，算不了）、一次可比性检查；写作模型只引用拆解的判定语。模型都换成脚本。
