Heuristic weak unfold applied rule call right

And obtained the following new goals

Proof step 6:
m4 + # lpt = # avol, avol[0] = mapped(buf), avol[m1] = mapped(buf0), avol[m0] = mapped(buf1), m = LEB_SIZE, disk-layout(mksb(adr, m5, m0, m1, m2, m3, m4), # lpt), is-encoded(log, buf1), is-encoded(lpt, lebs(avol, m3, lptlebs(# lpt, LEB_SIZE))), is-encoded(mksb(adr, m5, m0, m1, m2, m3, m4), buf), is-encoded-pad(orphans, m2, buf0), mapped-full?(avol, m3, lptlebs(# lpt, LEB_SIZE)), logoff ≠ LEB_SIZE → # buf1 = logoff ⊦ ⟪boolvar := logoff = m⟫ true
