Proof step 1 from proof inv-change (conclusion)

v ∈ avols, v = default-volid, ebm-cons(avols), m < # avols[v], n ≤ LEB_SIZE, n ≤ # buf, is-aligned(n, EB_PAGE_SIZE) ⊦ ⟪ebm_vol_change#(m, n, buf, v; avols; err)⟫ (v ∈ avols ∧ ebm-cons(avols))

System applied rule normalize

And obtained the following new goals
