Arbiter.

Arbiter is the deterministic routing function at the centre of the Mickai cooperative. It inspects every inbound request, the operator's clearance, the active tenant, and the policy graph, and dispatches to the correct specialist brain or set of brains. For high-stakes actions it convenes a quorum. Determinism is the central property: the same request, in the same context, with the same policy, always routes the same way. That determinism is what makes the audit ledger replayable.

• 01Route every request to the correct domain or kernel brain
• 02Convene multi-brain quorums for high-stakes actions
• 03Enforce the deterministic routing contract for replay and audit
• 04Surface unanimous, majority, and conflicted outcomes to the operator

Authoritative external corpora and standards this brain treats as canonical. Every retrieval against these sources is signed into the audit ledger so a regulator can prove which evidence drove which output.

Mickai-native tooling primitives this brain implements internally. Codex for sovereign plain-text graph PKM, Lectern for spaced-repetition memory, Stele for citation-provenance, and domain-native primitives layered on top. No external services in the trust path; data stays on operator-personalised hardware.
