Once Value Remediation Report

Apply at most one idempotent write and turn the accepted and skipped counts into a commit, skip, or retry remediation action.

idempotent write Only the first write is accepted and later writes are counted as skipped, so the remediation action is reproducible without a live one-shot value cache.
