Without a time grain, the offset join columns that align shifted dates to original dates are never created. The join falls back to raw column values, producing silently wrong results (identical values instead of shifted data). Replace the existing dead-code validation with a check that raises a helpful error early. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
