A schematic destined for a 94V0 PCB must have explicit "net classes" for high voltage. Finally, he plugged the board into the test rig
Most hobbyist CM4 breakout boards use standard FR-4 (rated 94V0 by default from reputable fabs). However, many low-cost fabs use non-compliant materials. When reviewing CM4 schematics, insisting on ensures: insisting on ensures:
