The probe daemon runs as root outside every sandbox profile. After its GPU test it writes the unified log since boot as gzip text into m2v/zz-oslog, which the cache export ships with the UFS log, so the host sees every process's os_log lines without another export channel.

// Adreno probe daemon: started by launchd from an owner job (a union view over /System/Library/LaunchDaemons, see the boot-time addon

// mount), so it runs outside every sandbox profile. It waits for the Adreno accelerator service to appear, runs the shared userspace GPU
|

// test once, then writes the system log for the UFS log export (NativeOsLogExport.mm) and exits. The test result reaches the kernel through

// the driver's progress markers and SetMetadata.
