Proof step 12 from proof validstatfields-initundone (previous step)

validstatfield(str, statfields(class) .first, st) ⊦ statfields(class) = [], initdone(class, st), tdname∃(str, class)

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 11:
statfields(class) = sk + sks, validstatfield(str, sk, st) ⊦ statfields(class) = [], initdone(class, st), tdname∃(str, class)

Rule argument

[speclemmaarg: sks ≠ [] ,sk = sks .first ∧ sks0 = sks .rest ↔ sks = sk + sks0 ,[sks, sk, sks0] → [statfields(class), sk, sks] ,T ,list-data ,storekeys ,elim-list-c ]
