Proof step 54 from proof junkrefs-notin (previous step)

¬ (r0 ≠ jvmref ∧ (¬ is_valid_ref(str, r0, st) ∨ ¬ st[r0 -- _type] .type ≤ ty)), ∀ str, r, refs0, ty, st. (junkrefs(str, acc + r ' + refs0, ty, st) ↔ junkrefs(str, acc + r ', ty, st)) ∨ r ∈ st ⊦ junkrefs(str, (r0 ' + acc) + r ' + refs0, ty, st) ↔ junkrefs(str, (r0 ' + acc) + r ', ty, st), r ∈ st

And obtained the following new goals

Proof step 4:
⊦ ¬ junkrefs(str, jvmref ' + refs, ty, st)
Proof step 53:
is_valid_ref(str, r0, st), st[r0 -- _type] .type ≤ ty, ∀ str, r, refs0, ty, st. (junkrefs(str, acc + r ' + refs0, ty, st) ↔ junkrefs(str, acc + r ', ty, st)) ∨ r ∈ st ⊦ junkrefs(str, (r0 ' + acc) + r ' + refs0, ty, st) ↔ junkrefs(str, (r0 ' + acc) + r ', ty, st), r0 = jvmref, r ∈ st
