+# ENG-09 全包影响、文档与提交检查整合
+
+本任务整合三个已独立提交的子项：ENG-AUDIT-01（e0aacc5d）、ENG-IMPACT-01（6abac891）
+和ENG-COVERAGE-01（f35fb876）。不重复计算其单元测试，也不将工程门槛当作包发布验收。
+
+| 验收项 | 实际实现和限制 |
+| --- | --- |
+| 核心/共享变更触发全生态 | impact-policy及实际导入/manifest关系，核心影响22包；六类CI门槛保持执行，未知路径扩大范围 |
+| 每完成任务独立提交 | commit-audit读取真实Git状态迁移及证据；DOC-01至04仅有固定历史bootstrap例外 |
+| 契约与版本责任 | 12类契约×22包有归属，29个冻结版本对照点；不据此推断连续支持窗口 |
+| 测试与报告对应 | 固定ID、断言标题、真实Node事件和候选输入指纹；当前10项精确索引，255行仍需补录 |
+| 文档/CI一致 | 静态表检查、命令接入顺序及必需workflow检查可运行；大型/动态报告进入既有CI artifact目录 |
+
+本轮重跑提交审计、影响分析、契约/文档检查并保存结构化整合结果。完整主CI918项及
+44项重复观察执行沿用子项f35fb876对应的证据，未因本轮只改文档/状态重新宣称全套执行。
+精确来源见 [整合验证](../baselines/engineering-integration.json)。
+
+仍需后续各包契约任务逐成员映射与类型/浏览器/设备/SDK验证，CI-04负责真实远端运行；
+REVIEW/REL负责发布准入。当前统一安装消费者只有core/chapter，其他包的历史专属测试
+不能被统一脚本范围替代。本任务不推送或发布。完成后按独立commit审计本任务自身。
