+2026-10-12 用户通过本聊天选项明确批准“授权增加这项治理修复，继续完成全部交付”。新增范围限 scripts/svc.sh 版本目录唯一性/拒绝覆盖，以及 tests/test_svc_u2.py 固定时钟回归；不改分支保护、发布流程、存储/权限设计。根因：svc_release_id 秒级命名，同源同秒目录相同；svc_release_stage rm -rf 删除前一制品，回退 prev/new 为同一目录，旧版本已丢失。固定时钟最小重放已稳定复现，完整输出由 evidence 保存。方案：目录名加入调用进程身份；创建目标目录采用排他 mkdir，重复 ID 拒绝，不覆盖原目录。回归覆盖同一时刻成功版→失败版→恢复成功版与原字节。I2 按用户授权继续测试/Review/当前 HEAD CI/合入。
