Proof step 10 from proof rm-vl-in-before-h (previous step)

eq-entry(n, lref) ∈ (lref0 = lref ⊃ q0 - lref;eq-entry(m, lref0) ' + (q0 - lref)), ∀ n, lref. ¬ eq-entry(n, lref) ∈ q0 - lref ⊦ lref0 = lref

And obtained the following new goals

Proof step 11:
eq-entry(n, lref) ∈ q0 - lref, ∀ n, lref. ¬ eq-entry(n, lref) ∈ q0 - lref ⊦ eq-entry(n, lref) = eq-entry(m, lref0), lref0 = lref

Rule argument

Additional information

Used simplifier rules: ⊦ eq-entry(m, lref) = eq-entry(m0, lref0) ↔ m = m0 ∧ lref = lref0; (ws)%a: ⊦ (q + q0) + q1 = q + q0 + q1; from specification list[erasequeue-base]% ⊦ eqent ∈ eqent0 ' + q ↔ eqent = eqent0 ∨ eqent ∈ q; (s)
