Proof step 34 from proof inv-add-log-leb (previous step)

# buf = EB_PAGE_SIZE, # lpt = # avol, rofs ↔ false, bleb = buffered(m0), m = m4, m0 = m3, wbuf = mkwbuf(buf, m1, m2), ebm-vol-inv(avol), bleb ≠ nobuffer → bleb.leb < # avol ∧ wbuf-cons(mkwbuf(buf, m1, m2), avol[bleb.leb], false), bleb = buffered(m3) ∨ (bleb = nobuffer ∨ m2 = 0) ∧ m3 < # avol ∧ avol[m3].mapped? ∧ m4 = # avol[m3].data ⊦ ⟪skip⟫ (# wbuf.content = EB_PAGE_SIZE ∧ (bleb ≠ nobuffer → bleb.leb < # avol ∧ wbuf-cons(wbuf, avol[bleb.leb], false)))

Heuristic symbolic execution applied rule skip right

And closed the goal!
