Proof step 16 from proof prepost-encode-lpt (previous step)

# buf = lptsize(n1 + n0, LEB_SIZE), # lpt = n1 + n0, is-encoded(lpt, buf, n0) ⊦ n1 = 0, n0 * ENCODED_LPROPS_SIZE + encoding-size(lpt[n0]) ≤ # buf ∧ buf = buf

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 17:
# buf = lptsize(n1 + n0, LEB_SIZE), # lpt = n1 + n0, # buf < n0 * ENCODED_LPROPS_SIZE + ENCODED_LPROPS_SIZE, is-encoded(lpt, buf, n0) ⊦ n1 = 0
