SKILL: Arbitrary Write to Code Execution — Expert Attack Playbook

AI LOAD INSTRUCTION: Expert techniques for converting an arbitrary write primitive into code execution. Covers every major overwrite target organized by glibc version compatibility: GOT, __malloc_hook, __free_hook, _IO_FILE vtable, __exit_funcs, TLS_dtor_list, _dl_fini, modprobe_path, .fini_array, C++ vtable, and setcontext gadget. This is the "last mile" skill. Base models often target hooks that no longer exist (post-glibc 2.34) or miss pointer mangling requirements.
