Proof step 14 from proof add-putbar-rew (previous step)

¬ r1 ≠ r0 ⊦ r = r0, (r1 -- fs ' ∈ addobj(r0, class, fis, st) ↔ r1 -- fs ' ∈ addobj(r0, class, fis, putByteArray(bytes, r, i, st))) ∧ (addobj(r0, class, fis, st)[r1 -- fs ']) = (addobj(r0, class, fis, putByteArray(bytes, r, i, st))[r1 -- fs '])

And obtained the following new goals

Proof step 5:
⊦ r -- sk ∈ addobj(r, class, fis, st) ↔ ¬ ¬ (sk ∈ fis ∨ sk = _type ∨ r -- sk ∈ st)
Proof step 13:
⊦ r = r0, (addobj(r0, class, fis, st)[r0 -- fs ']) = (addobj(r0, class, fis, putByteArray(bytes, r, i, st))[r0 -- fs '])
