Arduino+a5+checkm8+exclusive

Kaelen had written a custom assembly shim. The Arduino would pull the A5’s debug enable pin low for exactly 17.3 nanoseconds, then blast a 512-byte payload over a serial clock line—a digital picklock for a ghost in the silicon.

Kaelen frowned. “Exclusive?” He typed ls -la / . arduino+a5+checkm8+exclusive
