A consistency check is needed to ensure that the full ecc op table constructed at step $i$ of the merge protocol is identical to the "previous" ecc op table utilized at step $i+1$. This can be done via a commitment consistency check in the circuit that recursively verifies the $i+1$th merge proof. The mechanism is similar to that used for the Databus consistency checks.
