Can a Pilot doublecheck orders from a controlling persona to prevent spoofing?
Yes, but this is a horribly inefficient way to do things, as the agent/drone in question will not act until it receives verification. This means that the drone needs to take an action to ask for order verification, and the controlling persona needs to take an action to confirm the orders, which means losing at least 1 Initiative Pass every time you issue orders. Note also that the verification request could be intercepted, and the verification also spoofed.
