Proof step 20 from proof crash-neutral-read (previous step)

# buf = n1 + n0 + n, pebs[m3] = mkpeb(buf0, m1, false), m3 < # pebs, mtd-cons(pebs), m2 + n ≤ PEB_SIZE, n0 + n ≤ # buf ⊦ ∃ buf1. # buf1 = # buf ∧ range=(buf1, 0, buf, 0, n0) ∧ range=(buf1, n0 + n, buf, n0 + n, n1) ∧ ⟨buf := buf1⟩ true

User applied rule exists right

And obtained the following new goals

Proof step 21:
# buf = n1 + n0 + n, pebs[m3] = mkpeb(buf0, m1, false), m3 < # pebs, mtd-cons(pebs), n0 + n ≤ # buf, m2 + n ≤ PEB_SIZE ⊦ # buf = # buf ∧ range=(buf, 0, buf, 0, n0) ∧ range=(buf, n0 + n, buf, n0 + n, n1) ∧ ⟨buf0 := buf⟩ true
