merge(chv-muse-round12): 合入 P6 privsep worker + 确定性安全检查层 (81e4eaf)
唯一冲突是文档 §15 撞号：P6 一节顺延为 §17，基线说明更新 （P3 已在树里，接线走真实代码）。chv-sync.sh 自动合入正确： P6 的 worker 路径与 P3 的 authd 路径（useHttpPath）都在。 P6 测试 43 项全过（skipped=1 是 root 下 uid 否定测试）。

"""对齐 Muse P6 测试：privsep worker + 确定性安全检查层。
|
||||
|
||||
只用标准库与 mock，绝不启动真实 VM、不联网、不含真实 token
|
||||
（测试值全是假值）。覆盖：
|
||||
- 安全检查层：注入规则每档至少一个 block/flag/allow 用例（含中英）、
|
||||
真实 git 输出样式不误报、脱敏全模式、来源标记随数据走、审计里
|
||||
绝无密钥值、审计失败不中断；
|
||||
- privsep 协议：请求/响应校验、白名单（客户端与服务端各拒一次）、
|
||||
仓库 confinement、超时与 worker 崩溃 → 类型化失败；
|
||||
- worker 真 socket 回路：pull/push/status/ping、唯一仓解析、helper
|
||||
缺失 fail-closed、git argv 里只有 helper 配置绝无 token、输出先
|
||||
扫描后返回、block 阻断、flag 标记；
|
||||
- chv-sync.sh 委托：worker 在时走 worker、不在时走旧路径 + 警告；
|
||||
- 执行器推理边界审计钩子：只记指纹、不记值、失败不中断。
