Proof step 12 from proof inv-read (previous step)

err0 = ESUCCESS, avols[v][m2].mapped?, m2 < # avols[v], ebm-cons(avols), v ∈ avols, n0 + n ≤ # buf, m1 + n ≤ LEB_SIZE, ⌊err0⌋ ∨ err0 = ESUCCESS ⊦ ⟪buf := copy(avols[v][m2].data, m1, buf, n0, n)⟫ true

Heuristic symbolic execution applied rule assign right

And obtained the following new goals
