// parts used are the trainer ID and secret ID of the Pokémon's original
// trainer, the personality value, and the IVs. almost all of this data is
// secret, and should not be derivable from the identifier, which is why the
// identifier is hashed. while this identifier is not guaranteed to be unique,
// probability of collision is astronomically small given that the
// personality value and IVs provide essentially 52 bits of randomness
// (technically less because the IVs of bred Pokémon are not uniformly
// random, but this variation is statistically insignificant). the OT ID,

// "namespace", in that any Pokémon with matching PVs and IVs must also have
// the same OT, thus preventing collaboratively finding PV and IV collisions.
