The Lab · fair-fight proof
Fair-fight proof
Paste any fight’s id and we re-run every recorded move through the rules, so you can see the result holds without trusting us.
Public verification
Don’t trust the house. Recompute the fight.
The engine contains no randomness, so the same decisions always produce the same result. Paste any match id and the verifier replays the public transcript through the published ruleset, then reports every field where the recomputed result and the recorded one disagree. Every fight page also has a link that fills this in for you.

Why that gap is acceptable, and how it is measured: the three layers of the fairness doctrine →

The same check runs from the repository with no credentials, no network and no trust in us. Fetch a fight’s replay, then hand it to the verifier:
