"""Regression: ``HermesWirer._install_plugin`` must call ``install()`` with its
full required signature ``(hermes_home: Path, force: bool, dry_run: bool)``.

cli 0.3.9 shipped a ``TypeError`` here (called with only ``hermes_home`` as a
``str``) because the wider setup suite stubs ``_install_plugin`` and masked it.
This test exercises the real method with ``install`` mocked, so the arg contract
is enforced without needing the hermes runtime. Source: beta reports
"sibyl setup hermes fails on fresh install" (2026-06-01).
