Proof step 6 from proof prepost-decode-lpt (previous step)

# buf = lptsize(# lpt, LEB_SIZE), buf0 = buf, err = ESUCCESS, lpt0 = lpt, n = 0 ⊦ n ≤ # lpt ∧ # buf = lptsize(# lpt, LEB_SIZE) ∧ # lpt = # lpt ∧ (err = ESUCCESS ∨ ⌊err⌋ ) ∧ (err = ESUCCESS → is-encoded(lpt, buf, n))

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 7:
# buf = lptsize(# lpt, LEB_SIZE) ⊦ is-encoded(lpt, buf, 0)
