Proof step 6 from proof inv-get-volume-size (previous step)

# buf = EB_PAGE_SIZE, # lpt = # avol, ebm-vol-inv(avol), bleb ≠ nobuffer → bleb.leb < # avol ∧ wbuf-cons(mkwbuf(buf, m0, m1), avol[bleb.leb], rofs) ⊦ ⟪apersistence_io_get_volume_size#(adr, m, plog, avol, lpt, ns; ; n)⟫ true

Heuristic unfold applied rule call right

And obtained the following new goals

Proof step 7:
# lpt = # avol, # buf = EB_PAGE_SIZE, ebm-vol-inv(avol), bleb ≠ nobuffer → bleb.leb < # avol ∧ wbuf-cons(mkwbuf(buf, m0, m1), avol[bleb.leb], rofs) ⊦ ⟪n := # avol⟫ true
