Proof step 3 from proof inv-recover (previous step)

ro.inodes?, fo0.inodes?, log-cons(log0, fs0), ri-inj(ri), ri-inj(fi0) ⊦ ⟪aubifs_core_recover#(boolvar0; ax, ks, fi0, ro0, fo0, log0, fs0; ri0, boolvar1, err)⟫ (err = ESUCCESS → boolvar1 ∧ ri-inj(ri0) ∧ ri-inj(fi0) ∧ log-cons(log0, fs0) ∧ ro0.inodes? ∧ fo0.inodes?)

Heuristic nonrecursive calls applied rule call right

And obtained the following new goals
