Prediction Archive · Signing Incident Disclosed
These rows preserve prediction payloads, claimed signing times, receipt IDs, and later outcomes. The legacy Ed25519 signer repeated the same R value across distinct messages. That nonce reuse means the key is cryptographically compromised, and these signatures must not be treated as trustworthy cryptographic proof. The archive remains public so the failure and the original record can be audited; no historical row will be silently re-signed.
