Proof step 5 from proof orphans-cons-gc-one (previous step)

orphans-cons(fs, ri, ro), ri-cons(ri, fs), key ∈ ri ⊦ adr ∈ fs, ∀ ino. inodekey(ino) ∈ ri[key, adr] → (fs[adr, fs[ri[key]]][ri[key, adr][inodekey(ino)]].nlink = 0 ∧ ino ≠ ROOT_INO ↔ inodekey(ino) ∈ ro)

And obtained the following new goals

Proof step 6:
orphans-cons(fs, ri, ro), ri-cons(ri, fs), inodekey(ino) ∈ ri[key, adr], key ∈ ri ⊦ fs[adr, fs[ri[key]]][ri[key, adr][inodekey(ino)]].nlink = 0 ∧ ino ≠ ROOT_INO ↔ inodekey(ino) ∈ ro, adr ∈ fs
