01
Commit before play
Each session begins with a server seed hash so the runtime is committed before results are known.
Fairness
Trust is a product surface, not just a sentence in the footer.
Violet Hand treats fairness as part of the operator experience. Session logic is server-authoritative, deterministic, and built to be replayed and verified after the fact.
02
Deal deterministically
Cards are derived from canonical deck rules and deterministic session sequencing rather than ad-hoc browser state.
03
Reveal after the session
When the session ends, the seed can be revealed so retained sessions can be checked against what really happened.
What this means in practice
The web app animates outcomes, it does not decide them.
Gameplay, fairness, replay reconstruction, retention, and plan gating all stay on the authoritative runtime side.
Replay exists because the runtime is structured.
Retained sessions are reconstructed from real session and round data, not from a fake video layer.
