Proof step 6 from proof sources-interfere (previous step)

cdom(co) ⇒ d, ∀ co, d. co ∈ cl0 ∧ cdom(co) ⇒ d → cdom(co) ∈ sources(cl0, d), co ∈ cl0 → cdom(co) ∈ sources(cl0, d) ⊦ cdom(co) ∈ sources(co0 ' + cl0, d), co ≠ co0 ∧ ¬ co ∈ cl0

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ sources(co ' + cl, d) = (((∃ d0. d0 ∈ sources(cl, d) ∧ cdom(co) ⇒ d0) ⊃ sources(cl, d) ++ cdom(co); sources(cl, d)))
