Walkthrough

A data-backfill operation is added to mark old syncs as backfilled by setting supports_diff to 1 after completing the existing expansion backfill pass. This prevents the migration from re-running on subsequent opens.

Changes

Cohort / File(s)	Summary
Backfill State Update pkg/dotc1z/grants.go	Adds post-backfill operation to mark old syncs (where supports_diff is 0) as backfilled by updating the column to 1, using syncRuns.Name() to target the correct table.

Poem

🐰 Hops with glee through data rows,
Old syncs marked where migration goes,
No repeat work, just one swift dance,
The backfill blooms with gentle prance! ✨
