Interface	Purpose	Notes
IAbilitySystemInterface	GetAbilitySystemComponent()	AMIPBasePlayerController, AMIPBasePlayerState, AMIPBasePlayerCharacter, AMIPBaseMob, UMIPBaseInventoryManagerComponent, UMIPItemInstance – used for GAS access.

Not MIP-specific; documented here for context. MIP uses it to resolve ASC from PC/PS/Pawn/Mob.
