The complete Mac body consumes a unit's type and path union, then normalizes a signed comparison to full EAX0/1. Its sole native caller passes a cursor from a room's typed unit list and tests the full return. Use existing D2UnitStrc* and four-byte BOOL, preserving selected names, all three stack slots, cdecl, the existing int* coordinate buffer and signed int distance. All target, caller, room/coordinate producers and path helpers were independently decoded. No Windows twin, shared layout, helper prototype or runtime/build change is claimed.
