Three Mac roster getters have undefined returns and int pRoster inputs. Preserve each selected pRoster name, existing single Stack4 formal and cdecl convention; type the input D2RosterStrc*. Level00075558 zero-extends WORD+0x20 into full EAX or returns0. Loot00075602/listen00075642 return0 fornull, otherwise GetFlag’s full EAX masked with1/2. The complete native helper ANDs its32-bit mask with DWORD flags; loot yields0/1 and listen0/2. All return uint32_t, and all11 caller sites consume full EAX. Complete raw Mac memory matches separate assembly for targets, four callers and relevant producer/callee paths; all19 PIC switch entries and every input/return route were verified. Inputs resolve only to existing typed roster traversal ornull. Current roster GUID+0x10 and level+0x20 fields agree. No selected-name, unused-formal, shared-layout or implicit-register helper change; no Windows ABI, Mac runtime or build claim.
