Proof step 7 from proof okbytearray-putrkvs (previous step)

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

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ validrefnotnull(str, r, mkarraytype(byte_type), st) ↔ okbytearray(r, st)
Proof step 6:
okbytearray(r, st), validvals(str, rkvs, st) ⊦ validrefnotnull(str, r, mkarraytype(byte_type), st[rkvs])

Rule argument

[crewrite-arg: validrefnotnull-bytearray , T , [str, r, st] → [str, r, st[rkvs]] ]
