Research direction
Start by reviewing the linked Jira issue BEAM-1029 for the missing context, then locate the ParDo, window-merging, and StateSpec validation entry points in the Java codebase. Add or update tests that demonstrate the invalid combination and confirm that validation occurs when window merging is used with a non-auto-combinable StateSpec.
