Independent browser verification

Your browser can reproduce this draw.

This check downloads the immutable v2 evidence package and FACTID's separate signing-key registry, then recomputes the digest, signature, commitments, randomness and winner selection locally with WebCrypto. No server-side verification verdict is trusted.

The browser first commits to its 256-bit client seed without revealing it. FACTID then seals the participant snapshot and its own 256-bit server-seed commitment. Only after both commitments exist are both seeds revealed and combined, so neither side can adapt its committed contribution after learning the other secret.
