Proof step 2 from proof abs-nodes-mkbuf0-empty-h (previous step)

⊦ abs-nodes(mkbuf(0), m, x, lax, weak) ↔ x = [] ∧ lax = []

User applied rule constructor cut

And obtained the following new goals

Proof step 3:
x = [] ⊦ abs-nodes(mkbuf(0), m, x, lax, weak) ↔ x = [] ∧ lax = []

Rule argument

var: x
