Heuristic symbolic execution applied rule assign right

And obtained the following new goals

Proof step 14:
pebs[m3] = mkpeb(buf0, m1, false), err0 = ESUCCESS, m3 < # pebs[m3, pebs[m3].data:= copy(buf, n2, pebs[m3].data, m2, n)], m3 < # pebs, is-aligned(m2, EB_PAGE_SIZE), is-aligned(n, EB_PAGE_SIZE), mtd-cons(pebs), m1 ≤ m2, m2 + n ≤ PEB_SIZE, n2 + n ≤ # buf, m2 + n ≤ # pebs[m3].data, ⌊err0⌋ ∨ err0 = ESUCCESS ⊦ mtd-cons (pebs[m3, pebs[m3].data:= copy(buf, n2, pebs[m3].data, m2, n)] [m3, pebs[m3, pebs[m3].data:= copy(buf, n2, pebs[m3].data, m2, n)][m3].fill:= (m2 + n) ])
