Proof step 4 from proof inv-is-readonly (previous step)

# lpt = # avol, # lpt0 = # avol, isbuf0 ↔ isbuf, log = log0, 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) ⊦ ⟪awbuf_is_readonly#(adr, m, log, avol, lpt, ns, bleb, isbuf0; ; isbuf)⟫ true

Heuristic unfold applied rule call right

And obtained the following new goals
