Proof step 6 from proof validsubset-okbytearray (previous step)

okbytearray(r, st), ∀ r. ¬ r ∈ st ∧ r ∈ st0 → ¬ junkref(str, r, st0), validref(str, r, mkarraytype(byte_type), st) → validref(str, r, mkarraytype(byte_type), st0) ⊦ okbytearray(r, st0)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ validref(str, r, mkarraytype(byte_type), st) ↔ okbytearray(r, st) ∨ r = jvmref
Proof step 5:
okbytearray(r, st), ∀ r. ¬ r ∈ st ∧ r ∈ st0 → ¬ junkref(str, r, st0), okbytearray(r, st) ∨ r = jvmref → validref(str, r, mkarraytype(byte_type), st0) ⊦ okbytearray(r, st0)

Rule argument

[crewrite-arg: okbytearray-validref, F, [st, r, str] → [st, r, str]]
