Proof step 13 from proof abs-nodes-at-least-flashsize (previous step)

lax.head = @(m0, m1), # buf1 + # buf0 < (2 * NODE_HEADER_SIZE + nd.alignedsize) + x0.flashsize, abs-nodes(buf0, m + # buf1, nd ' + x0, lax, false), abs-padding(buf1), ∀ buf2, x, m, lax. # buf2 < #(buf1 + buf0) → # buf2 < x.flashsize ∧ abs-nodes(buf2, m, x, lax, false) → x = [] ⊦

And obtained the following new goals

Proof step 14:
# buf1 + # buf0 < (2 * NODE_HEADER_SIZE + nd.alignedsize) + x0.flashsize, abs-nodes(buf0, m + # buf1, nd ' + x0, @(m0, m1) ' + lax0, false), abs-padding(buf1), ∀ buf2, x, m, lax. # buf2 < #(buf1 + buf0) → # buf2 < x.flashsize ∧ abs-nodes(buf2, m, x, lax, false) → x = [] ⊦
