Proof step 2 from proof is-encoded-pad-too-small (previous step)

# buf < ENCODED_NAT_SIZE ⊦ is-encoded-pad(ns, n, buf) ↔ ns = ∅ ∧ n = 0 ∧ is-aligned(# buf, EB_PAGE_SIZE)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 3:
# buf < ENCODED_NAT_SIZE ⊦ is-encoded-pad(ns, n, buf) ↔ ns = ∅ ∧ n = 0 ∧ is-aligned(# buf, EB_PAGE_SIZE)

Rule argument

Additional information

Used simplifier rules: ⊦ ENCODED_NAT_SIZE ≠ 0; (s)%f: ⊦ m < n → n ≠ 0; (forward) from specification nat-basic
