Proof step 78 from proof validrefs-putbar-01 (previous step)

refs = r0 + refs0, okbytearray(r, st), validrefs(str, refs, ty, putByteArray(bytes, r, i, st)) ⊦ refs = [], junkref(str, r0, st), validrefs(str, refs, ty, st)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 77:
okbytearray(r, st), validrefs(str, r0 ' + refs0, ty, putByteArray(bytes, r, i, st)) ⊦ junkref(str, r0, st), validrefs(str, r0 ' + refs0, ty, st)

Rule argument
