+- 误重启事故：PR #207 合入后 `make task-start` 再次以同名分支建卡（task-start 只校验本地分支可建，不查该名是否刚合入），空卡覆盖了 main 上的原卡；`3718f6c` 已恢复原卡，本轮复核证据行（被测 HEAD `c371815`：backend 四包 go test / examples / test-boundaries / make test 全 exit 0）追加于后，`make task-sync` 基线 63a62a7（tested `e37e0cd`）。
+- 本轮性质：**仅复核，不改公开面**——产品代码相对 origin/main 零差异（见证据行 no product diff）。
+- 待办移交：五仓 `v0.1.0` tag 与 `Agent-System-RDM` 建仓（12/13 号材料，owner 双钥匙）；MS0 评审时间待定（11 号对照包备好）。

+## 复核（2026-10-05）
+
+PR #207 合入后，`make task-start` 用同名分支在 main 之上重建，空模板覆盖了本卡。本提交把卡片恢复为 `63a62a79ac` 上已合入的正文。产品代码无新增差异（EXT-1 最小集已在该提交内）。P0 材料 11/12/13 同日按方案写在主检出 `.tmp/智能体系统/further-objective/`，不入库。下面的证据行是这次复核补记。
