Proof step 6 from proof add-nput-01 (previous step)

∀ r, class1, sk, val, fis0, st. addobj(r, class1, fis1 + (sk × val) ' + fis0, st) = (addobj(r, class1, fis1 + fis0, st)[r -- sk, val]) ∨ sk ∈ fis1 ⊦ (addobj(r, class1, fis1 + (sk × val) ' + fis0, st)[r -- sk0, val0]) = (addobj(r, class1, fis1 + fis0, st)[r -- sk0, val0][r -- sk, val]), sk = sk0, sk ∈ fis1

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ rk ≠ rk0 → (st[rk0, val][rk, val0]) = (st[rk, val0][rk0, val])
Proof step 5:
r -- sk ≠ r -- sk0, ∀ r, class1, sk, val, fis0, st. addobj(r, class1, fis1 + (sk × val) ' + fis0, st) = (addobj(r, class1, fis1 + fis0, st)[r -- sk, val]) ∨ sk ∈ fis1 ⊦ (addobj(r, class1, fis1 + (sk × val) ' + fis0, st)[r -- sk0, val0]) = (addobj(r, class1, fis1 + fis0, st)[r -- sk, val][r -- sk0, val0]), sk = sk0, sk ∈ fis1
