A single human-root keyholder and key pair that terminates a lineage chain. Every agent, tool, and service under that root carries signed derivation proofs — cryptographic ancestry, not personhood certification.
Collective identity through FROST threshold cryptography. No single human holds the full key. t-of-n participants required for every critical operation.
Organizational identity governed by multi-human threshold groups. Supports governance transitions, timelocked operations, and hierarchical descendant structures.
Three roots. One cryptographic chain. Privileged authority through typed lineage verification. Every action traceable to a human root.
