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

⊦ abs-nodes(buf0, x, lax, false) ∧ abs-nodes(buf1, # buf0, x0, lax0, false) ∧ # buf1 = x0.flashsize ∧ x0 ≠ [] → (abs-nodes((buf0 + buf1).align↓, x + x0, lax + lax0, boolvar) ↔ is-aligned(# buf0 + x0.flashsize, EB_PAGE_SIZE))

System applied rule normalize

And obtained the following new goals

Proof step 2:
# buf1 = x0.flashsize, abs-nodes(buf0, x, lax, false), abs-nodes(buf1, # buf0, x0, lax0, false) ⊦ abs-nodes((buf0 + buf1).align↓, x + x0, lax + lax0, boolvar) ↔ is-aligned(# buf0 + x0.flashsize, EB_PAGE_SIZE), x0 = []
