- check/presence.py：「提供《授权委托书》」「须提交投标函」这类要求按标题里有没有这个文件名判断，不调模型。
- 扫描件兜底：要附证明材料的要求没找到、投标文件里有扫描件页时，改为提示级「可能在扫描件里，请人工核对」。
- 响应方式解析时识别、带依据句子存进 checklist.response_modes（迁移 0008）；清单页显示、可改（写审计，
  重新解析不覆盖人工改过的）；查标用存下来的。新接口 PUT /projects/{id}/checklist/response-modes/{category}。
- check_item_result.layer 加 presence（迁移 0007）；契约同步默认接受的两种结论。

开发集 17 份：规矩投标文件的致命问题 120 → 51，致命级召回不变（22 / 32）（docs/architecture/check-eval.md §5）。

 **一处要说明的**：调响应方式识别时，打印结果里顺带出现了留出集 S03、S06、S09（招标文件本身，不是投标文件）的识别结果，其中 S03、S09 和规范 §2 的记录不一致。没有据此改任何规则，留到留出集正式评测时再看。
 
-## 5. 下一步
+## 5. 第三轮：扫描件兜底、文件要在、响应方式存进清单（2026-11-04）
 
-1. 证明材料和格式文件：扫描件兜底（C10）、文件要在（presence）按文件在不在判断。
-2. 响应方式存进清单、清单页显示并可改（C12 的人工确认点）。
-3. 第 2 步（投标侧结构识别、规则、C12 响应方式抽取）和第 3 步（整行上下文、偏离表直取、presence 判断）按 §2.2 的顺序改，每改一轮在开发集 14 份上重跑对比。
+**改了什么**：
+- **文件要在**（`check/presence.py`）：「提供《授权委托书》」「须提交投标函」这类要求，从原文取出文件名，在投标文件里找写着它的标题；找到就算已响应（出处是那个标题），不调模型。
+- **扫描件兜底**（C10）：要附证明材料的要求没找到、而投标文件里有扫描件页时，不报「未找到响应」，改成提示级「可能在扫描件里，请人工核对」。没有 OCR 时，扫描件里有没有这份材料分不出来。
+- **响应方式存进清单**（迁移 0008）：解析时识别、带依据句子存下来；清单页显示，可以改（人工确认点，写审计，重新解析不覆盖人工改过的）；查标用存下来的。
+
+| 指标（17 份） | 上一轮（mode） | 本轮（scan） |
+|---|---|---|
+| 查标召回 | 98 / 150（65%） | 92 / 150（61%） |
+| 致命级召回 | 22 / 32 | 22 / 32 |
+| 规矩的投标文件报出的问题 | 229（致命 120、重要 58、提示 51） | 235（**致命 51**、重要 14、提示 170） |
+| 规矩响应的要求上的误报 | 12.4 / 100 | 13.5 / 100 |
+
+**读法**：问题的个数没变，变的是级别：规矩的投标文件上的致命问题少了一半多（120 → 51），多出来的是「请到扫描件里核对」的提示，致命级召回不变。总召回掉了 4 个点，主要是批次变化带来的波动（文件要在的条目不再进模型，同一批里的组合变了），以及几条漏响应被「标题里出现了文件名」误判为已响应——要盯着。评测集里证明材料全是扫描件页，所以证明材料缺失（D02）照旧查不出、扫描件兜底也分不出缺没缺；真正查出来要靠 OCR / 多模态（S5）。

 3. 留出集（S03、S06、S09，风格 B + C，封存的词库）和真实国动投标文件，在第 3 步冻结代码后只跑一次。
