Proof step 6 from proof update-put (previous step)

∀ r, r0, st, sk, val. r = r0 ∨ (update(r0, fis0, st)[r -- sk, val]) = update(r0, fis0, st[r -- sk, val]) ⊦ r = r0, (update(r0, fis0, st)[r0 -- sk0, val0][r -- sk, val]) = (update(r0, fis0, st[r -- sk, val])[r0 -- sk0, val0])

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 ≠ r0 -- sk0, ∀ r, r0, st, sk, val. r = r0 ∨ (update(r0, fis0, st)[r -- sk, val]) = update(r0, fis0, st[r -- sk, val]) ⊦ r = r0, (update(r0, fis0, st)[r -- sk, val][r0 -- sk0, val0]) = (update(r0, fis0, st[r -- sk, val])[r0 -- sk0, val0])
