+"""Regression test for the int-coord write hotfix.
+
+PR #1953 added ``require_transform_for_georeferenced`` which raises when
+both spatial dims are present in ``da.coords`` and no transform was
+resolved. PR #1954 made ``coords_to_transform`` return ``None`` for
+integer-dtype x/y coords as a no-georef sentinel (#1949). Their
+interaction broke every writer call against an int-coord DataArray:
+the resolver returned ``None``, then the guard raised. This test
+locks in the int-dtype exemption that mirrors ``coords_to_transform``.
