"""
Shared test fixtures for the ais-check suite.

The tool ships as an executable named ``ais-check`` (no ``.py`` extension and a
hyphen), so it cannot be imported with a normal ``import`` statement. This shim
loads it from source as a module named ``ais_check`` and exposes it as a
session-scoped fixture.
