Proof step 4 from proof abs-nodes-aligned-headersize-h (previous step)

abs-nodes(buf, m, x, lax, weak), ∀ buf0, m, x, lax, weak. # buf0 < # buf → abs-nodes(buf0, m, x, lax, weak) → is-aligned(# buf0, NODE_HEADER_SIZE) ⊦ is-aligned(# buf, NODE_HEADER_SIZE)

User applied rule constructor cut

And obtained the following new goals

Proof step 5:
x = [], abs-nodes(buf, m, x, lax, weak), ∀ buf0, m, x, lax, weak. # buf0 < # buf → abs-nodes(buf0, m, x, lax, weak) → is-aligned(# buf0, NODE_HEADER_SIZE) ⊦ is-aligned(# buf, NODE_HEADER_SIZE)
Proof step 15:
x = nd + x0, abs-nodes(buf, m, x, lax, weak), ∀ buf0, m, x, lax, weak. # buf0 < # buf → abs-nodes(buf0, m, x, lax, weak) → is-aligned(# buf0, NODE_HEADER_SIZE) ⊦ is-aligned(# buf, NODE_HEADER_SIZE)

Rule argument
