Proof step 3 from proof onlymod-is-update (previous step)

∀ st2, r, st. # st < # st1 → (onlyModified(r, st, st2) → (∃ fis. st2 = update(r, fis, st) ∧ validFields(r, fis, st))) ⊦ ∃ fis. st1 = update(r, fis, st1) ∧ validFields(r, fis, st1)

Heuristic quantifier closing applied rule exists right

And obtained the following new goals

Proof step 1:
⊦ update(r, [], st) = st
Proof step 2:
⊦ validFields(r, [], st)
