Proof step 13 from proof validfieldlist-put-statfield (previous step)

rk .ref = jvmref, r ≠ jvmref ∨ ¬ rk .key ∈ sks ⊦ validfieldlist(str, r, sks, st[rk, val]) ↔ validfieldlist(str, r, sks, st)

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Rule argument

[speclemmaarg: ,r = rk .ref ∧ sk = rk .key ↔ rk = r -- sk ,[rk, r, sk] → [rk, r0, sk] ,T ,refkey , ,elim ]
