otool and dyld_info print the operand path before a slice's records, and the Mach-O parsers read that header as output. A file name holding `Load command` blocks or `(from lib)` lines therefore added a forged LC_MAIN entrypoint, corrupted the Mach header fields, and injected imports and exports into `inspect_macho`. Strip the exact echoed operand header (`<path>:`, `<path> (architecture <arch>):`, `<path> [<arch>]:`) before parsing. Output without that header, such as replayed captures, is parsed unchanged.
