Proof step 16 from proof prepost-wl-get-used-min (previous step)

¬ boolvar ↔ used-ecs(wlar, m0) = ∅, wlar[vtblpnum] = wl-entry(m, stat), wlar[m0] = wl-entry(m1, used), m0 < # wlar, boolvar → vtblpnum < # wlar, boolvar → vtblpnum < m0 ∧ stat = used ∧ m = used-ecs(wlar, m0).min, ¬ boolvar ∨ m1 < m ⊦ m1 = (wlar[m0].status = used ⊃ used-ecs(wlar, m0) ++ wlar[m0].ec;used-ecs(wlar, m0)).min ∧ (wlar[m0].status = used ⊃ used-ecs(wlar, m0) ++ wlar[m0].ec;used-ecs(wlar, m0)) ≠ ∅

And obtained the following new goals

Proof step 17:
¬ boolvar ↔ used-ecs(wlar, m0) = ∅, wlar[vtblpnum] = wl-entry(m, stat), wlar[m0] = wl-entry(m1, used), m0 < # wlar, boolvar → vtblpnum < # wlar, boolvar → vtblpnum < m0 ∧ stat = used ∧ m = used-ecs(wlar, m0).min, ¬ boolvar ∨ m1 < m ⊦ m1 = (used-ecs(wlar, m0) ++ m1).min
