The deepest layer answers to no single authority.
Beneath every module, beneath Materia K itself, there exists a final layer of control. The Foundation is the root authority of the entire KEPOS framework — the layer that can override any module, revoke any credential, halt any process, and if necessary, initiate a complete system reset. It is the layer of last resort. Access to the Foundation is not granted through credentials or permissions. It is architecturally restricted to a specific operational context that can only be activated through a multi-party consensus protocol. No single person, no single key, no single command can invoke it. The Foundation exists because every system, no matter how autonomous, needs a final authority. But unlike conventional root access, the Foundation cannot be compromised through privilege escalation, social engineering, or insider threat — because the conditions for its activation are distributed, time-bound, and cryptographically enforced. It is the emergency brake that cannot be pulled accidentally and cannot be pulled by an adversary.
