Proof step 4 from proof lookup-1init-01 (previous step)

∀ r, r0, j, st, sk. r = r0 ∨ (addarray(r, vals0, j, st)[r0 -- sk]) = st[r0 -- sk] ⊦ r = r0, (addarray(r, val + vals0, j, st)[r0 -- sk]) = st[r0 -- sk]

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
⊦ addarray(r, val ' + vals, i, st) = (addarray(r, vals, i + 1, st)[r -- i ', val])
Proof step 3:
∀ r, r0, j, st, sk. r = r0 ∨ (addarray(r, vals0, j, st)[r0 -- sk]) = st[r0 -- sk] ⊦ r = r0, (addarray(r, vals0, j + 1, st)[r0 -- sk]) = st[r0 -- sk]

Rule argument
