Proof step 27 from proof payload-copy-right-upper (previous step)

payload(copy(zbrar, n0 + 1, zbrar, 2 + n0, nused0)[n0 + 1, zbrar[n0]], 2 + n0, nused0) = payload(copy(zbrar, n0 + 1, zbrar, 2 + n0, nused0), 2 + n0, nused0), n0 + nused0 + 1 < # zbrar, n0 + 1 < # zbrar, n0 < # zbrar, ∀ n, zbrar. n + nused0 < # zbrar → payload(copy(zbrar, n, zbrar, n + 1, nused0), n + 1, nused0) = payload(zbrar, n, nused0) ⊦ payload(copy(zbrar, n0 + 1, zbrar, 2 + n0, nused0), 2 + n0, nused0) = payload(zbrar, n0 + 1, nused0), zbrar[n0].entry?

Heuristic quantifier closing applied rule all left

And closed the goal!
