And obtained the following new goals

Proof step 31:
# buf = EB_PAGE_SIZE, # lpt = # avol, avol[m3] = mapped(buf0), m3 < # avol, ebm-vol-inv(avol), bleb ≠ nobuffer → bleb.leb < # avol ∧ wbuf-cons(mkwbuf(buf, m1, m2), avol[bleb.leb], false), bleb = nobuffer ∨ m2 = 0 ⊦ bleb = buffered(m3), is-aligned(# buf0, EB_PAGE_SIZE)
