What would you lead?

Would you make a different lead on the identical auction but with the
explanation that 4NT was RKCB?

What evidence do you require from the declaring side to support their
agreements when there is a different explanation on each side of the
screen.  In particular at the end of the hand declarer said that 4NT
was RKCB but later changed is mind stating that it was waiting.  The
had no documentation to back up either agreement.
