"""Checks of the integration sweep plan that need no Docker.

The sweep itself runs against a live Gitea (``tests/integration/test_sweep.py``). These
tests make sure the plan stays consistent with the catalog: every tool gets arguments that
pass its schema, every tool is called exactly once in a sensible order, and every override,
allowance and exclusion names a real tool.
