The verify path is the product
Verify this leaderboard
Anyone can re-verify the signed per-axis Elo leaderboard: the browser recomputes the canonical body, derives the content_id, and checks the Ed25519 signature against the recorded pubkey. No trust in us is required. Nothing leaves your machine.
1. Recompute
Canonical body → sha256 → content_id, in-browser.
2. Check key
Ed25519 verify against the recorded pubkey.
3. Trust nothing
No login, no key, no record left on the machine.
Measurement, not certification. Every score carries n + a 95% CI; a thin-n axis is reported honest ("not sufficient to rank"), never invented. This is the piece neither a usage-rank gateway nor a crowd-Elo board offers: a number a third party can re-verify, free.
