Public-surface Decryption Blast Radius scores for the 20 largest US retail banks, updated nightly via Certificate Transparency log mining. Higher score = more harvested traffic unlocks when quantum decryption arrives in the 2030s. The most damning signal for this sector is cross-rotation private-key reuse: when a cert renews but the underlying key persists, every harvested handshake from that entire window shares one quantum-failure point.
