Proof step 4 from proof add-okbar (previous step)

⊦ r = r0, okarray(r, byte_type, addobj(r0, class, fis, st)) ↔ okbytearray(r, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ okbytearray(r, st) ↔ okarray(r, byte_type, st)
Proof step 3:
⊦ r ≠ r0 → (okarray(r, ty, addobj(r0, class, fis, st)) ↔ okarray(r, ty, st))

Rule argument

[speclemmaarg: ,okbytearray(r, st) ↔ okarray(r, byte_type, st) ,[st, r] → [st, r] ,F ,okfuns , ,okbytearray-01 ]
