+- 本轮基线 `35ca7299c`。删除前独立审计发现：主 Skill/MCP 入口无直接引用，不等于台账无读者。证据包索引仍登记全部拟删台账，完整性检查会验证目标路径；派生视图和研究矩阵也保留引用。原清单直接删除会造成缺失路径回归，初期因此暂缓；产品补充授权后已完成精确删除与引用修复，索引缺失路径仍为零。交付状态见本轮进度记录。
+- 防复发：资料删除清单必须同时追踪索引、派生视图、泛扫描生成器和测试；保留 blocked/reference-only 等声明限制，不能为清理而抹掉限制。详见 `docs/tasks/TASK-owner-case-purge-fix-20260919.md`（补充范围已授权）。另发现完整性校验器不支持索引内 12 个既有状态，基线与当前一致；未将其改为通过，另留验收缺口。
+- 本机预检远端 verified，但 focused tests 有一条既有碎片分类断言失败；Python 全量收集缺 mcp/hypothesis；快速门缺 mcp。前端基线构建因外部依赖 junction 边界失败，webpack 补验因 Windows symlink EPERM 失败，Static/gzip 无完整产物。均不得写成通过。验收清单在 `docs/testing/owner-case-purge-20260919.md`。
