## Title

    Recompute the basis, compare-and-swap every row, and roll back the whole batch

## Body

    Load and validate the complete manifest before mutation. Recompute each row's current basis before classifying a no-op, and keep a distinct stale-basis outcome when the stored target value is not backed by current payload. Apply updates with a compare-and-swap predicate containing the basis verified in phase one; any failed swap, row error, identity divergence, or safety-gate mismatch must abort the batch and roll back all writes in one transaction. Execute the same fail-closed gates in dry-run and commit, and couple the zero-write receipt to the transaction outcome.
