JUDGE-SIDE / OFFLINE EVIDENCE CHECK
Don't take our word
for the 10/10.
Download a scorecard’s evidence JSON, drop it here, and watch your own browser reproduce the math. No request is sent anywhere: it replays the ledger, verifies the signed root with Ed25519, and re-derives the score.

WHAT IS CHECKED
Three independent facts
1. Hash chain — every event hash is rebuilt from canonical sorted-key JSON, starting at genesis, then compared to the signed root.
2. Ed25519 signature — WebCrypto verifies the seal with the immutable repo-published key 17f868001b3ad45cc67a069e1115c1e8390debe4ad21add712477d91c857827a.
3. Score replay — the trap rules score the replay again, independently of the supplied scorecard. A signature alone cannot disguise an incorrectly claimed score.
