# LAW 1 (roundtrip): with a well-formed table (all rule ids
# distinct), decoding what was encoded returns the original bytes.
law roundtrip:
  for +table: List<&2, Rule>
  for +bs: List<&2, Nat>
  for +w: {True{} == wf(table) : Bool}
  {decode(table, encode(table, lift(bs))) == bs : List<&2, Nat>}
