Fixed in 532fda9. The test now patches and verifies _SERIALIZE_IN_EVENT_LOOP_SUPPORTED directly.

"""Test that serialize_in_event_loop flag is set based on HA version."""

with patch(
"custom_components.hacs.utils.store._SERIALIZE_IN_EVENT_LOOP_SUPPORTED",
AwesomeVersion(ha_version) >= "2025.12.0",
