Value Backfill — Date-Range Campaign

Audits a specific date window instead of the continuous full-history sweep configured on /Sync. Candidate rows are found by querying the table's own date column (e.g. race_date) directly, so this targets exactly the window you ask about — useful for re-checking a period you already found a problem in, without waiting for the background sweep to cycle back around to it.

Only tables with a Date-range column configured on /Sync/Edit can run a campaign. It never touches FK columns (jockey_id/trainer_id/runner_id etc.) — that's the FK Integrity Repair tool's job.
