Proof step 4 from proof inv-change (previous step)

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

Heuristic symbolic execution applied rule if positive right

And obtained the following new goals
