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

okbytearray(r, st), validvals(str, rkvs, st) ⊦ validrefnotnull(str, r, mkarraytype(byte_type), st[rkvs])

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ validrefnotnull(str, r, ty, st) ↔ r ≠ jvmref ∧ validref(str, r, ty, st)
Proof step 5:
okbytearray(r, st), validvals(str, rkvs, st) ⊦ r ≠ jvmref ∧ validref(str, r, mkarraytype(byte_type), st[rkvs])

Rule argument

[crewrite-arg: validrefnotnull-def , F , [st, ty, r, str] → [st[rkvs], mkarraytype(byte_type), r, str] ]
