Proof step 16 from proof crash-neutral-read-buf (previous step)

# lpt = # avol, # buf = n0 + n, avol[m3] = mapped(buf0), m3 < # avol, awbuf-inv(avol, bleb), synced(avol0), avol0 ↓ avol, m0 + n ≤ LEB_SIZE ⊦ ∃ buf1. # buf1 = n0 + n ∧ range=(buf1, n, buf, n, n0) ∧ ⟨buf := buf1⟩ true

User applied rule exists right

And obtained the following new goals

Proof step 17:
# buf = n0 + n, # lpt = # avol, avol[m3] = mapped(buf0), m3 < # avol, awbuf-inv(avol, bleb), synced(avol0), avol0 ↓ avol, m0 + n ≤ LEB_SIZE ⊦ # buf = n0 + n ∧ range=(buf, n, buf, n, n0) ∧ ⟨buf0 := buf⟩ true
