Proof step 7 from proof inv-change (previous step)

m < # avols[v], ebm-cons(avols), is-aligned(n, EB_PAGE_SIZE), v ∈ avols, n ≤ # buf, n ≤ LEB_SIZE, ⌊err0⌋ ∨ err0 = ESUCCESS ⊦ ⟪err := err0; if err = ESUCCESS then avols[v][m] := mapped(subarray(buf, 0, n) + mkempbuf(LEB_SIZE - n), n)⟫ ebm-cons(avols)

Heuristic symbolic execution applied rule assign right

And obtained the following new goals
