Proof step 5 from proof refine-get-buf (previous step)

# avol0 = # avol, # lpt0 = # avol, # buf = EB_PAGE_SIZE, abs(avol, bleb, mkwbuf(buf, m, m1), avol0, rofs), awbuf-inv(avol, bleb), ebm-vol-inv(avol0), bleb ≠ nobuffer → bleb.leb < # avol ∧ wbuf-cons(mkwbuf(buf, m, m1), avol0[bleb.leb], rofs) ⊦ ⟪wbuf_get_buf#(bleb; ; bleb1)⟫ ⟨awbuf_get_buf#(adr0, m0, plog0, avol, lpt0, ns0, bleb, rofs; ; bleb2)⟩ (bleb1 = bleb2)

Heuristic unfold applied rule call right

And obtained the following new goals

Proof step 6:
# buf = EB_PAGE_SIZE, # lpt0 = # avol, # avol0 = # avol, bleb0 = bleb3, abs(avol, bleb3, mkwbuf(buf, m, m1), avol0, rofs), awbuf-inv(avol, bleb3), ebm-vol-inv(avol0), bleb3 ≠ nobuffer → bleb3.leb < # avol ∧ wbuf-cons(mkwbuf(buf, m, m1), avol0[bleb3.leb], rofs) ⊦ ⟪bleb := bleb0⟫ ⟨awbuf_get_buf#(adr0, m0, plog0, avol, lpt0, ns0, bleb3, rofs; ; bleb2)⟩ (bleb = bleb2)
