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

jmaxino ≠ 0, key.inode?, jro < jmaxino, fi.inos < jmaxino, pmaxino ≤ jmaxino ⊦ ⟪gjournal_orphans_insert#(key; jmaxino, jro)⟫ (jro < jmaxino ∧ pmaxino ≤ jmaxino ∧ fi.inos < jmaxino ∧ jmaxino ≠ 0)

Heuristic unfold applied rule call right

And obtained the following new goals

Proof step 4:
key.inode?, fi.inos < jmaxino, jro < jmaxino, pmaxino ≤ jmaxino ⊦ ⟪if key.inode? then {jro := jro ++ key.ino; jmaxino := max(key.ino + 1, jmaxino)} else abort⟫ (jro < jmaxino ∧ pmaxino ≤ jmaxino ∧ fi.inos < jmaxino ∧ jmaxino ≠ 0), jmaxino = 0

Rule argument

pos: right 1
