Editorial v1. Scores are derived from public design documents, NIST PQC literature (ML-KEM / ML-DSA / SLH-DSA), and project disclosures as of June 2026. Adoption and security weights are conservative; lower confidence means we have less independent evidence. Disagree with a score? Email support@quantumcryptorisk.com with sources.
