  # When `CONDUKT_BASHKIT_DISABLE=1` is set at compile time the module is
  # generated as plain Elixir stubs that raise when called: no Rust
  # toolchain is invoked, no `.so` is mapped into the BEAM, and BEAM
  # teardown is unaffected. Use this on environments where the bashkit
  # NIF cannot be loaded safely (currently: GHA Linux runners, where a
  # loaded NIF triggers a teardown segfault under investigation).

    # don't get inferred as `none()` by the Elixir 1.19 typer (which
    # would mark every `case`/`with` clause that matched success as
    # unreachable, breaking --warnings-as-errors). The default test
    # suite excludes :virtual_sandbox so these are never invoked anyway.
