Proof step 8 from proof prepost-encode-lpt (previous step)

buf = mkbuf(lptsize(# lpt, m0)), err = ESUCCESS, m0 = LEB_SIZE, n = 0 ⊦ n ≤ # lpt ∧ # buf = lptsize(# lpt, LEB_SIZE) ∧ (err = ESUCCESS ∨ ⌊err⌋ ) ∧ (err = ESUCCESS → is-encoded(lpt, buf, n))

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 9:
⊦ is-encoded(lpt, mkbuf(lptsize(# lpt, LEB_SIZE)), 0)

Rule argument

Additional information

Used simplifier rules: ⊦ # mkbuf(n) = n; (s)% ⊦ 0 ≤ m; (s)
