Proof step 16 from proof hasSharing-rec (previous step)

hasSharing(r, st) ∨ hasSharing(refs, st) ⊦ hasSharing(r ' + refs, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 8:
⊦ hasSharing(refs, st) ↔ (∃ r. r ∈ refs ∧ hasSharing(r, st))
Proof step 15:
hasSharing(r, st) ∨ (∃ r. r ∈ refs ∧ hasSharing(r, st)) ⊦ hasSharing(r ' + refs, st)
