WHY IT NEEDS A POLICY

Why set_track_mute needs a policy

This tool modifies the mute state of a mixer track in FL Studio, which is a reversible write operation — unmuting restores the previous state. No data is deleted, no code is executed, and no financial transaction occurs. Blast radius is low as it only affects audio playback state of one track.
