Proof step 9 from proof validvals-putrkvs (previous step)

validvals(str, rkvs0, st), validvals(str, rkvs1, st), rkv ∈ rkvs0 ⊦ validval(str, rkv .1, rkv .2, st[rkvs1])

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 8:
rkv = rk × val, validvals(str, rkvs0, st), validvals(str, rkvs1, st), rkv ∈ rkvs0 ⊦ validval(str, rk, val, st[rkvs1])

Rule argument

[speclemmaarg: ,rk = rkv .1 ∧ val = rkv .2 ↔ rkv = rk × val ,[rkv, rk, val] → [rkv, rk, val] ,T ,pair ,refkeyvalues ,elim ]
