Heuristic unfold applied rule call right

And obtained the following new goals

Proof step 7:
fs0 = fs, log0 = log, ro.inodes?, fo.inodes?, log-cons(log, fs), ri-cons(ri, fs), ri-inj(ri), ri-inj(fi) ⊦ ⟨choose kx, ax with ¬ dups(kx) ∧ ¬ dups(ax) ∧ new(ax, fs) ∧ kx.toSet ⊆ dom ri ∧ # kx = # ax ∧ ax.toSet ∩ log.toSet = ∅ in {fs[ax] := fs[ri[kx]], log := log + ax; ri[kx] := ax}; aubifs_core_gc_drop#(ri, log; fs); boolvar := ?⟩ (boolvar ∧ fs0 = fs ∧ log0 = log)
