Proof step 6 from proof abs-orphans (previous step)

afs-cons(abs-dirs(fs, ri), abs-files(fs, ri)) ⊦ ino ∈ orphans(abs-dirs(fs, ri), abs-files(fs, ri)) ↔ inodekey(ino) ∈ ri ∧ fs[ri[inodekey(ino)]].nlink = 0 ∧ ino ≠ ROOT_INO, ino = ROOT_INO

Heuristic simplifier applied rule simplifier

And obtained the following new goals
