Proof step 3 from proof abs-nodes-nospace-header-h (previous step)

# buf < 2 * NODE_HEADER_SIZE + align↑(m, 2 * NODE_HEADER_SIZE), abs-nodes(buf, n, x, lax, weak), is-encoded(nodeheader(m, boolvar0), subarray(buf, 0, NODE_HEADER_SIZE)), NODE_HEADER_SIZE ≤ # buf ⊦ abs-failed(buf) ∧ x = [] ∧ lax = [] ∧ weak

User applied rule constructor cut

And obtained the following new goals

Proof step 4:
x = [], # buf < 2 * NODE_HEADER_SIZE + align↑(m, 2 * NODE_HEADER_SIZE), abs-nodes(buf, n, x, lax, weak), is-encoded(nodeheader(m, boolvar0), subarray(buf, 0, NODE_HEADER_SIZE)), NODE_HEADER_SIZE ≤ # buf ⊦ abs-failed(buf) ∧ x = [] ∧ lax = [] ∧ weak
Proof step 12:
x = nd + x0, # buf < 2 * NODE_HEADER_SIZE + align↑(m, 2 * NODE_HEADER_SIZE), abs-nodes(buf, n, x, lax, weak), is-encoded(nodeheader(m, boolvar0), subarray(buf, 0, NODE_HEADER_SIZE)), NODE_HEADER_SIZE ≤ # buf ⊦ abs-failed(buf) ∧ x = [] ∧ lax = [] ∧ weak
