  • Adds an acceptance-test that essentially replicates the TestInteropFaultProofs action test scenario in a supernode devstack.
  • Restore the kona prestate build script for easier local development.

part of #19010

Looks good generally - but the first couple of tests are failing (in CI and for me locally).

I thought I checked this locally. I can confirm this. And it looks like a bug in kona (or divergence from op-program) where it handles the super state transitions unexpectedly when interop is disabled.

@ajsutton it should be fixed now. I've tweaked kona to follow op-program behavior -

block, err := deriveOptimisticBlock(logger, bootInfo, l1PreimageOracle, l2PreimageOracle, superRoot, transitionState, tasks)
if errors.Is(err, ErrL1HeadReached) {
return InvalidTransitionHash, nil
.
Which I believe is correct.
