Proof step 5 from proof instore-rec-03 (conclusion)

⊦ instore(r, class, fv ' + fis, st) ↔ (r -- fv .1) × fv .2 ∈ st ∧ instore(r, class, fis, st)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 4:
⊦ instore(r, class, fv ' + fis, st) ↔ r -- fv .1 ∈ st ∧ st[r -- fv .1] = fv .2 ∧ instore(r, class, fis, st)
