Proof step 3 from proof inv-orphans-contains (previous step)

key.inode?, jro < jmaxino ⊦ ⟪gjournal_orphans_contains#(key, jro; jvalid)⟫ true

Heuristic weak unfold applied rule call right

And obtained the following new goals

Proof step 4:
key.inode?, jro < jmaxino ⊦ ⟪if key.inode? then jvalid := key.ino ∈ jro else abort⟫ true

Rule argument

pos: right 1
