11"""A development schema that exists only to exercise the fixtures CLI. 

12 

13``fixtures refresh`` acts only on schemas still in development, and every 

14schema is finalized during a release, so a test that named a real one would 

15stop exercising the path it claims. This double is never finalized. 

16 

17It is defined in the test tree, so ``available_schema_classes`` never returns 

18it for ``lsst.images``: it is never frozen, published, or part of shipped 

19data. Tests reach it by passing this module as the CLI's ``--package``, which 

20selects this schema and no other. 

21 

22This is a plain module rather than a test module so importing it registers the 

23schema deterministically, independent of pytest's collection order.
