Proof step 7 from proof vals-at (previous step)

n ≤ # bytes0, ∀ n0. ¬ # bytes0 ≤ n0 → (mkjavavalues(bytes0)[n0]) = byteval(bytes0[n0]) ∨ bytes0 = [] ⊦ (byteval(by) ' + mkjavavalues(bytes0))[n] = byteval((by ' + bytes0)[n])

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
n ≠ 0 ⊦ (by ' + bytes)[(* n)] = bytes[n -1]
Proof step 6:
n ≠ 0, n ≤ # bytes0, ∀ n0. ¬ # bytes0 ≤ n0 → (mkjavavalues(bytes0)[n0]) = byteval(bytes0[n0]) ∨ bytes0 = [] ⊦ (byteval(by) ' + mkjavavalues(bytes0))[n] = byteval(bytes0[n -1])
