Proof step 35 from proof validval-putrkvs (previous step)

¬ r -- _type ∈ rkvs, sk .fs = mkfs(class, ty, fieldvar), is_indexkey(sk), validvals(str, rkvs, st), validval(str, val, st[r -- _type] .type .type, st) ⊦ validval(str, val, st[r -- _type] .type .type, st[rkvs])

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 21:
⊦ validvals(str, rkvs, st) → ¬ r -- _type ∈ rkvs
Proof step 34:
sk .fs = mkfs(class, ty, fieldvar), is_indexkey(sk), validvals(str, rkvs, st), validval(str, val, st[r -- _type] .type .type, st) ⊦ validval(str, val, st[r -- _type] .type .type, st[rkvs])
