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

# lpt = # avol, avol[m3] = mapped(buf0), err0 = ESUCCESS, n = 0, m3 < # avol, ebm-vol-inv(avol), is-aligned(m0, EB_PAGE_SIZE), is-aligned(n, EB_PAGE_SIZE), # buf0 ≤ m0, m0 + n ≤ LEB_SIZE, n2 + n ≤ # buf, ⌊err0⌋ ∨ err0 = ESUCCESS ⊦ ⟪skip⟫ (ebm-vol-inv(avol) ∧ # lpt = # avol)

Heuristic symbolic execution applied rule skip right

And closed the goal!
