// One trait pairing each managed command code with its request and reply wire
// types. Not a multi-implementor abstraction (there is one wire contract and one established
// band): a compile-time assertion that the code/type pairings match, giving
// the SDK one generic send path and LaserData Cloud's dispatch table a fixture test
// against the same pairings.
