Proof step 2 from proof abs-nodes-no-padding-one (previous step)

# buf = a '.flashsize ⊦ abs-nodes(buf, m, a ', lax, false) ↔ lax = @(m, # buf) ' ∧ abs-node(buf, a)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ a ' = a + []
Proof step 4:
# buf = (a + []).flashsize ⊦ abs-nodes(buf, m, a + [], lax, false) ↔ lax = @(m, # buf) ' ∧ abs-node(buf, a)

Rule argument

spec: list name: One seq: ⊦ a ' = a + [] subst: [a] → [a] flags: <all paths>
