Proof step 1 from proof abs-nodes-crash-h (conclusion)

⊦ abs-nodes(buf, m, x, lax, true) ∧ is-aligned(n, NODE_HEADER_SIZE) ∧ n ≤ # buf → (∃ x0, lax0. x0 ⊑ x ∧ lax0 ⊑ lax ∧ abs-nodes(subarray(buf, 0, n), m, x0, lax0, true))

System applied rule normalize

And obtained the following new goals

Proof step 2:
abs-nodes(buf, m, x, lax, true), is-aligned(n, NODE_HEADER_SIZE), n ≤ # buf ⊦ ∃ x0, lax0. x0 ⊑ x ∧ lax0 ⊑ lax ∧ abs-nodes(subarray(buf, 0, n), m, x0, lax0, true)

Proof step 1 from proof abs-nodes-crash-h (conclusion)
