# End-to-end: build the io_uring smoke binary, package it into an OCI image,
# run it inside Apple `container` (or any compatible runtime), and check the
# exit code.
#
# This validates that:
#   * zig/src/iouring.zig compiles for Linux
#   * std.os.linux.IoUring works on the kernel inside Apple's lightweight VM
#   * IORING_OP_ACCEPT_MULTISHOT delivers all expected accepts
#
# This is a correctness check, NOT a benchmark. Per AGENTS.md, no perf
# numbers should be cited from this script.
