    // kill the entire test binary process (not just this test), truncating
    // the whole `cargo test` run while still reporting exit code 0. Passing
    // a harmless real flag (`--buffer-size 256`, the documented default)
    // keeps `has_args = true` and exercises the same "activation not passed"
    // path without tripping that exit.
