This is very courtesy-of-claude, but the existing test here fails a lot of checkers for the wrong reason — a lot of them are failing because the meta line has no lean field, and nanoda would decline without that because of the strict ordering requirements it imposes on ndjson numbering and ordering.

This modified test provides the recursors, and MyBool.rec's recursor is the one a buggy kernel might provide, instead of the correct Prop-restricted one.

rpylean fails to reject the proof (on account of trusting the provided recursors) and accepts a proof of false. (And zignodamus declines where it could just reject, due to panicking.)
