Proof step 64 from proof junkref-update-equiv (conclusion)

⊦ ¬ path∃(str, r, r0, st) ∧ ¬ _type ∈ fis ∧ is_valid_ref(str, r0, st) ∧ validFields(r0, fis, st) → (junkref(str, r, update(r0, fis, st)) ↔ junkref(str, r, st))

And obtained the following new goals

Proof step 63:
validFields(r0, fis, st), is_valid_ref(str, r0, st) ⊦ junkref(str, r, update(r0, fis, st)) ↔ junkref(str, r, st), path∃(str, r, r0, st), _type ∈ fis
