Proof step 66 from proof validref-putrkvs (previous step)

rkv = rk × val, validref(str, r, ty, st), validval(str, rk, val, st), validvals(str, rkvs0, st), ∀ str, r, ty, st. validref(str, r, ty, st) ∧ validvals(str, rkvs0, st) → validref(str, r, ty, st[rkvs0]) ⊦ validref(str, r, ty, st[rkv ' + rkvs0])

And obtained the following new goals

Proof step 65:
validref(str, r, ty, st), validval(str, rk, val, st), validvals(str, rkvs0, st), ∀ str, r, ty, st. validref(str, r, ty, st) ∧ validvals(str, rkvs0, st) → validref(str, r, ty, st[rkvs0]) ⊦ validref(str, r, ty, st[(rk × val) ' + rkvs0])
