Proof step 7 from proof validstatfields-put-byteval-01 (conclusion)

⊦ ¬ validstatfields(str, st[r -- sk, byteval(by)]) ∧ r ≠ jvmref ∧ ¬ is_indexkey(sk) ∧ sk .fs .type = byte_type → ¬ validstatfields(str, st)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 6:
sk .fs .type = byte_type, validstatfields(str, st), is_fskey(sk) ⊦ r = jvmref, validstatfields(str, st[r -- sk, byteval(by)])

Rule argument
