Proof step 30 from proof sharing-twopaths (previous step)

st[r -- sks0] = refval(refs0 .last), validrefs(str, st[r -- sks] .refval ' + refs0, mkclasstype(`java.lang.Object' .class), st), fits(r, sks, st), fits(r, sks0, st) ⊦ refs0 .last = jvmref, st[r -- sks] .refval = jvmref, sks0 = [], sks = [], sks = sks0, r = jvmref, refs0 = [], hasSharing(r, st), sks ⊑ sks0

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 29:
st[r -- sks] = refval(r0) ∧ is_referencevalue(st[r -- sks]), st[r -- sks0] = refval(refs0 .last), validrefs(str, r0 ' + refs0, mkclasstype(`java.lang.Object' .class), st), fits(r, sks, st), fits(r, sks0, st) ⊦ refs0 .last = jvmref, r0 = jvmref, sks0 = [], sks = [], sks = sks0, r = jvmref, refs0 = [], hasSharing(r, st), sks ⊑ sks0
