The Program Said the Cage Was Locked. I Asked the Kernel.

The user verified a sandbox implementation by querying the kernel instead of relying on program reports. By checking /proc/status for processes 10920 and 10922, it was confirmed that the agent process lacked Seccomp filters while the worker process, designed to run model-written code, had a filter loaded. This verification confirmed the network block was applied specifically to the worker process, marking the first independent validation of the project's security framework.
