The original Mac callback is registered through pointer slot3962b0, whose original value is2bb344 and whose sole read forwards it to MessagePump. Full original producer/dispatcher bodies prove that exact route and an intentional one-DWORD frame index starting at0 and incrementing. Existing int(int) frame-pump metadata and the paired Windows callback's RET4 corroborate the interface. This implementation ignores its frame argument but always writes fullEAX1 at its sole normal exit. Recover int __cdecl(int nFrameIndex), preserving the already-identical selected function name and locals. Mac RET0 and dispatcher-owned outgoing area establish its own convention; Windows stdcall is not imported. No shared funcdef, pointer slot, other callback, virtual interface, global or behavior edit.
