Proof step 13 from proof inv-read (previous step)

# lpt = # avol, avol[m3] = mapped(buf1), m3 < # avol, ebm-vol-inv(avol), n2 + n1 ≤ # buf, m0 + n1 ≤ LEB_SIZE, ⌊err0⌋ ∨ err0 = ESUCCESS ⊦ err0 = ESUCCESS, ∃ buf1. # buf1 = # buf ∧ range=(buf, 0, buf1, 0, n2) ∧ range=(buf, n2 + n1, buf1, n2 + n1, # buf - n2 + n1)
