Proof step 3 from proof hasSharing-self (previous step)

st[r -- sks] = refval(r), fits(r, sks, st) ⊦ sks = [], r = jvmref, ∃ sks1, sks2. fits(r, sks1, st) ∧ fits(r, sks2, st) ∧ sks1 ≠ sks2 ∧ st[r -- sks1] .refval ≠ jvmref ∧ st[r -- sks1] = st[r -- sks2]

Heuristic quantifier closing applied rule exists right

And obtained the following new goals

Proof step 2:
⊦ fits(r, [], st)

Rule argument

[EXRARG : pos: right 3, [QUANTTERMLIST : ([], sks)]]
