- 分层流水线：只读操作零延迟直通，灰区才调用审查模型（实测 ~0.7–1.5s）
- 灾难命令黑名单：删盘/格式化/递归删除根目录等**不经任何模型、确定性拦截**
- 弹窗分级可配：模型"拿不准"时可以选择弹窗问你、硬拒或放行（`onUncertain`）
- 逃生舱：被拒的命令支持一次性批准（精确匹配、用后即焚、审计留痕）
- 逃生舱：被拒的命令支持一次性批准（绑定目录/工具/会话、用后即焚、审计留痕）
- 防注入：模型伪造"用户已同意"等授权文字会被识别为注入并直接拒绝
- 常驻 daemon：审查连接热复用、决策缓存、配置热重载
- 常驻 daemon：双向 HMAC 身份校验、审查连接热复用、上下文绑定缓存、配置热重载
- 审计日志：每次决策（放行/拒绝/来源/耗时）全部落盘可查
