Proof step 3 from proof crash-neutral-orphans-remove (previous step)

key.inode?, ro.inodes?, fo.inodes?, log-cons(log, fs), ri-inj(ri), ri-inj(fi) ⊦ ⟨aubifs_core_orphans_remove#(key, ri, fi, fo, fs, log, true; ro)⟩ true

Heuristic unfold applied rule call right

And obtained the following new goals

Proof step 4:
boolvar ↔ true, key.inode?, fo.inodes?, ro.inodes?, log-cons(log, fs), ri-inj(fi), ri-inj(ri) ⊦ ⟨if key.inode? then ro := ro -- key else abort⟩ true

Rule argument

pos: right 1
