feat(chv): 对齐 Muse P5 纵深——eBPF 污点传播 + 五档严格能力 + 对话外审批 + 默认策略
- taint.py：污点追踪器（登记/污点不可逆/子进程继承/审计） - ebpf_taint.py：eBPF 程序源码 + 加载器（能力探测 + 降级）； 本机实测加载被 seccomp 挡（bpf() EPERM），报 blocked 不冒充 - capabilities.py：五档严格能力（一次/会话/任务/时限/永久， 三元组绑定 + 精确匹配 + 撤销；permanent 默认不签发） - policy.py：默认策略规则表 + 谨慎度三档（写操作与敏感路径 永远不自动放行，规则变化审计） - approval_channel.py：对话外审批通道（nonce + 15 分钟过期 + HMAC，答复一次有效，对话伪造无效） - sentinel.py 接线：evaluate() 可选接 taint/policy/tier/scope， 不传时行为与 P3 一致；自动放行步骤 + 档位签发回落单次； Capability 基类属性放宽为 Optional（None = 不限） - 新测试 61 项；全量 cloud 套件 1958 项 OK（skipped=8） 真机待验证（未做，排队在 round-11 之后）：见 docs/chv-muse-p5-gap.md §4

"""对齐 Muse P5-C 测试：对话外审批通道。

只用标准库，绝不启动真实 VM、不联网、不含真实 token

原因/过期，无密钥、无凭证值、无用户数据内容）；

- 合法答复校验通过并 resolve；

- nonce 对不上被拒、过期答复被拒、签名不对被拒、

未知 pending_id 被拒、答复重放被拒、verdict 非法被拒；
|

- 否定测试（核心）：对话内容里出现的“批准/同意/allow”
|

字样（模拟一段 agent 对话文本含伪造的 pending_id 与
|

verdict）走通道校验一律无效——没有合法 nonce 与签名。

- 污点进程失去自动放行、回到正常审批流（审计带 tainted）；

- permissive 档干净进程可放行未白名单主机，但仍挡写操作、
