Scope comes before the label
Operator Originals, named games and third-party games can use different systems. Each listed record should be read with its documented scope: an Originals verifier says nothing by itself about a third-party slot catalogue.
What a useful verifier exposes
Strong documentation explains the server seed, client seed, nonce or cursor, the pre-bet commitment or hash, the result calculation, and how a player can reproduce the outcome after the seed is revealed.
What this ranking does not prove
We do not audit source code or verify live bets. The score rewards public technical documentation and clear boundaries. It is not a certification of implementation quality.
