+- Harness Control Plane 在 `tools/execute` 分发边界识别当前 Session 和在途请求。
- Harness Control Plane 禁止 `sandbox_permissions` 升级。
+- `write`、`edit`、`bash` 与 `pwsh` 固定拒绝，不能仅靠系统提示词保持只读。

- 工具不能自行更换工作区根。
+- DSH 本地 Filesystem、Bash 或 PowerShell Provider 直接使用 GoodBuddy 客户端当前用户的 OS 权限。

+- 工作区不是 containment 边界；绝对路径和命令可访问当前用户本来有权访问的主机资源。
- 只有真实沙箱拒绝后的同一操作，才可请求一次升级。
+- Main 代理的 MCP 工具继续执行分配、schema、活动请求、模式和 RuntimeAuthorizer 校验。
 - Main 不调用 `ToolApprovalBroker`，而是对当前 Execute 请求自动返回 `allow-once`；界面不进入等待审批状态，也不弹出审批对话框。
 - 所有工具调用仍作为活动事件记录；Ask 和 delegation 路径继续固定拒绝。
 - Harness Control Plane 不接受 `allow_always`，也不把未知结果解释为允许。
