The Mac helper has an int pMsg formal and one-byte undefined result, while native ECX is the actual existing mouse-message pointer and every return defines fullEAX0/1. All3 callers forward their current D2UIMouseMsgStrc* formal unchanged in ECX and immediately TEST fullEAX; their native bHandled+24/dwResult+28 writes independently establish nominal record role. Use existing D2UIMouseMsgStrc* and4-byte BOOL, preserving pMsg, selected function name, soleECX4 slot, current __fastcc, arity and locals. Complete616Mac bytes across target/allcallers match separate assembly, each argument/return/branch checked. Normal MOVZX EAX,AL then XOR1 and explicit full-zero early return justify BOOL rather than1-byte bool. No ABI recovery, guessed second input, union/POINT alias, layout/global/caller changes, pending metadata premise, rename, Windows/runtime/build gain or withdrawn-claim refile.
