Proof step 8 from proof inv-write-data (previous step)

pebs[m3] = mkpeb(buf0, m4, false), m3 < # pebs, is-aligned(m2, EB_PAGE_SIZE), is-aligned(n, EB_PAGE_SIZE), mtd-cons(pebs), m4 ≤ m2 + 2 * EB_PAGE_SIZE, m2 + n ≤ LEB_SIZE, n0 + n ≤ # buf ⊦ ⟪mtd_asm_write#(m3, m2 + 2 * EB_PAGE_SIZE, n0, n, buf; pebs; err)⟫ mtd-cons(pebs)

User applied rule insert program lemma

And obtained the following new goals

Rule argument
