NIST 800-53 Rev 5 — the canonical control taxonomy.
Every regulatory framework KYE Protocol™ maps to crosswalks INTO this hub. When a procurement form asks "do you map to PCI DSS 4.0?" or "Annex III of the EU AI Act?", the answer is deterministic: follow the crosswalk to the NIST control(s), then to the KYE™ artefact that binds it. One hop, machine-readable, no N×M explosion.
JSON: /.well-known/nist-800-53-hub.json. Schema: kye.nist_800_53_hub.v1.
The pattern — N + M, not N × M
Without a hub, every framework-to-framework crosswalk is N × M (170 frameworks ⇒ 380 directed pairs). With NIST 800-53 as the hub, it is N + M — one hop per side.
EU AI Act Art 6 → NIST 800-53 RA-3 + PM-9 → KYE Risk Engine + canonical Implementation Registry entry
GDPR Art 30 → NIST 800-53 PT-3 + AU-2 → data_use_manifest.v1 + audit-chain emission
SOC 2 CC6 → NIST 800-53 AC-2/3/6, IA-2/5 → Entity Engine + Authority Engine + PDP
HIPAA §164.312 → NIST 800-53 AC-2/3, AU-2, SC-8/12 → per-tenant signing-kid registry + TLS 1.3 floor
