Proof step 6 from proof abs-nodes-unique-weak-h (previous step)

x0 = [], abs-nodes(buf, m, x0, lax0, true), abs-nodes(buf, m, x1, lax1, true), ∀ buf0, m, x0, lax0, x1, lax1. # buf0 < # buf → abs-nodes(buf0, m, x0, lax0, true) ∧ abs-nodes(buf0, m, x1, lax1, true) → x0 = x1 ∧ lax0 = lax1 ⊦ x0 = x1 ∧ lax0 = lax1

And obtained the following new goals

Proof step 7:
abs-nodes(buf, m, [], [], true), abs-nodes(buf, m, x1, lax1, true), ∀ buf0, m, x0, lax0, x1, lax1. # buf0 < # buf → abs-nodes(buf0, m, x0, lax0, true) ∧ abs-nodes(buf0, m, x1, lax1, true) → x0 = x1 ∧ lax0 = lax1 ⊦ [] = x1 ∧ [] = lax1
