The thunk dispatches host_ui_interface vslot +4; the default host implementation at 0x431520 logs the raw text and calls age_show_message_box@0x409370. Flag 0x10000 appends `FILE=%s ADDRESS=%X LINE=%d COMMAND=%s(%d) DEPTH=%d`; low mode 4 formats `%s%s`, uses caption `エラーが発生しました`, and calls USER32 MessageBoxA with style 0x40 (MB_OK|MB_ICONINFORMATION). The optional command metadata at ctx+0x6ddac and source-line maps at ctx+0x6f798 are zero-initialized and have no writer in Himegari's release image, yielding `LINE=-1 COMMAND=-(436)` at this opcode. The opcode ignores the return, then calls msvc_string_erase(buffer,0,0xffffffff). SYSTEM4's sole site presents its invalid-execution-mode text and value; a following 0x1b3 appends CRLF to the now-empty accumulator."
