Proof step 5 from proof inv-orphans-insert (previous step)

key.inode?, jro < jmaxino, fi.inos < jmaxino, pmaxino ≤ jmaxino ⊦ ⟪jro := jro ++ key.ino; jmaxino := max(key.ino + 1, jmaxino)⟫ (jro < jmaxino ∧ pmaxino ≤ jmaxino ∧ fi.inos < jmaxino ∧ jmaxino ≠ 0), jmaxino = 0

Heuristic symbolic execution applied rule assign right

And obtained the following new goals

Proof step 6:
