Proof step 35 from proof inv-read-gnd (previous step)

# lpt0 = # avol, # lpt = # avol, avol[m4] = mapped(buf1), m4 < # avol, abs-node(subarray(buf1, m3, m2), gnd), awbuf-inv(avol, bleb), buf-ro-rw-mode(isbuf, bleb, lpt0, avol), bufs-log-only(bleb, log0, lpt0), lpt-free-unref(lpt), lpt-leb-size(lpt), lpt-ram-flash(lpt0, lpt, log0), m3 + m2 ≤ # buf1, ⌊err0⌋ ⊦ ∃ buf. # buf = m2

User applied rule exists right

And closed the goal!
