Proof step 22 from proof validstatfields-subset (conclusion)

⊦ validstatfields(str, st) ∧ st ⊆ st0 ∧ init(str, st) ∧ init(str, st0) → validstatfields(str, st0)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 21:
init(str, st0), init(str, st), st ⊆ st0, validstatfields(str, st) ⊦ validstatfields(str, st0)

Rule argument
