Agent Trust Card system fixes bugs, enhances security against key compromise

The author addresses feedback on the Agent Trust Card (ATC) system, detailing fixes for canonicalization bugs that affected signature verification. The system now uses RFC 8785 for JSON Canonicalization Scheme, ensuring consistent key sorting and preventing nested object double-encoding across different programming languages. Additionally, the author outlines a three-layer strategy for handling Certificate Authority (CA) key compromise, including key rotation, a signed revocation list with a 60-second TTL, and planned multi-signature ATCs for high-value agents.
