If a Sprite uses Trap on Patrol IC, can the Patrol IC even make Perception checks? Would the Host know about the Trapped Patrol IC and launch other IC?

Can the Complex Form Diffusion be used against an entire Host?

Can Editor be used on Encrypted Files?

No the Patrol IC is locked and can't do anything that requires an action ..
 includes perception ... but yes the host would know and could launch more IC ... Trap is not subtle

Diffusion can be used against a host, but only one attribute at a time

The encryption needs to be best first
