Proof step 14 from proof onlymod-put-01 (previous step)

r -- sk ∈ st0, r ∈ st0 ⊦ sk = _length, sk = _type, (∀ rk. rk ∈ st ↔ rk ∈ st0[r -- sk, val]) ∧ (∀ r0, sk0. r0 ≠ r → st[r0 -- sk0] = st0[r0 -- sk0]) ∧ (r -- _type ∈ st → st[r -- _type] = st0[r -- _type]) ∧ (r -- _length ∈ st → st[r -- _length] = st0[r -- _length]) ↔ onlyModified(r, st, st0)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ onlyModified(r, st1, st2) ↔ (∀ rk. rk ∈ st1 ↔ rk ∈ st2) ∧ (∀ r0, sk. r0 ≠ r → st1[r0 -- sk] = st2[r0 -- sk]) ∧ (r -- _type ∈ st1 → st1[r -- _type] = st2[r -- _type]) ∧ (r -- _length ∈ st1 → st1[r -- _length] = st2[r -- _length])
Proof step 13:
r -- sk ∈ st0, r ∈ st0 ⊦ sk = _length, sk = _type, (∀ rk. rk ∈ st ↔ rk ∈ st0[r -- sk, val]) ∧ (∀ r0, sk0. r0 ≠ r → st[r0 -- sk0] = st0[r0 -- sk0]) ∧ (r -- _type ∈ st → st[r -- _type] = st0[r -- _type]) ∧ (r -- _length ∈ st → st[r -- _length] = st0[r -- _length]) ↔ (∀ rk. rk ∈ st ↔ rk ∈ st0) ∧ (∀ r0, sk. r0 ≠ r → st[r0 -- sk] = st0[r0 -- sk]) ∧ (r -- _type ∈ st → st[r -- _type] = st0[r -- _type]) ∧ (r -- _length ∈ st → st[r -- _length] = st0[r -- _length])
