Security. The embedded GPU could generate the bytes needed to encrypt data. A monitor watching for calls to a ChaCha20 library would miss the cipher rounds inside the model.

The model generated the tokens in this recording. The player decodes them into the warp, program block, instruction stages, four register lanes, and global-memory writes using the qwenGPU monitor's record format. A dot means the stream has not reported a register value. The left pane explains the experiment. The result card is an end-of-trial summary. Recorded compute time covers the launches and their checks; loading and compilation are separate. Guided playback speeds up long trials and advances between launches automatically.
