Proof step 1 from proof abs-node-abs-node-append-subarray (conclusion)

⊦ abs-node(buf, nd0) ∧ 2 * NODE_HEADER_SIZE + nd1.alignedsize ≤ # buf + # buf0 → (abs-node(subarray(buf + buf0, 0, 2 * NODE_HEADER_SIZE + nd1.alignedsize), nd1) ↔ nd0 = nd1)

System applied rule normalize

And obtained the following new goals

Proof step 2:
abs-node(buf, nd0), 2 * NODE_HEADER_SIZE + nd1.alignedsize ≤ # buf + # buf0 ⊦ abs-node(subarray(buf + buf0, 0, 2 * NODE_HEADER_SIZE + nd1.alignedsize), nd1) ↔ nd0 = nd1
