One package that makes the POSIX assumptions measured in W0-W8 hold in every process vLLM / vLLM-Omni starts, and reports what it did: - provides fcntl (flock/lockf on msvcrt.locking; LOCK_SH served as exclusive) and uvloop (asyncio.run on a selector loop) when absent; - installs WindowsSelectorEventLoopPolicy and a signal.signal fallback for loop.add_signal_handler on the Windows loop classes; - replaces whole vLLM's get_open_zmq_ipc_path / find_loaded_library when the wheel lacks the branch patch and the upstream body hash is known; - verifies the wheel-only sites (sentinel poll, int64 seed) and reports wheel_required at the exact site instead of failing downstream; - shm_dir() replaces the /dev/shm literals; os.geteuid provided. Activated from vllm_omni/patch.py and as vllm.general_plugins / vllm_omni.general_plugins entry points (idempotent; no-op off Windows). prints the audit; the M0 placement report embeds it. 16 Linux tests through injected primitives.
