The two-person rule for AI actions.
Some actions are too consequential for one signature. EMILIA Quorum holds a high-stakes, irreversible action until a quorum of named humans — M-of-N or in strict order, each bound to the exact action — has signed. The result is a cryptographic, offline-verifiable proof that the rule held for this exact action.
It is additive over single signoff: where one accountable human is enough, use FinGuard or GovGuard. Where the stakes demand more than one, require a quorum.
Where one approval is too small a target for the stakes.
A quorum either holds or it doesn’t.
A policy document that says “two people must approve” is only as strong as the system that enforces it. EMILIA Quorum makes the rule a fail-closed predicate, checkable by anyone:
Evidence, not testimony.
A decision log that says “three people approved” is testimony, controlled by the party who acted. A quorum receipt is evidence: an auditor, regulator, or counterparty can verify it offline, with open-source code, without trusting the system that issued it. To earn that, the verification is unambiguous enough that independent implementations agree — EMILIA ships three reference verifiers (JavaScript, Python, Go) that pass the same adversarial quorum vectors identically, on every change.
See it without trusting us. One command issues a dual-approval receipt, then verifies it offline — with EMILIA disconnected — and rejects a forged copy:

What’s real today.
Multi-party quorum is a verifiable protocol capability today: the three-language reference verifiers agree on it, the server-side enforcement that holds an action until the quorum is satisfied is built and merged into the authorization path, and a live in-browser demo runs an ordered three-party signoff and rejects a duplicate signer in front of you.
It is also verified end-to-end: an automated test drives three independent devices through an ordered signoff and proves a quorum-gated action cannot be consumed until every required human has signed. What is deliberately still ahead: a production deployment of that flow and — for defense — an accredited environment. We would rather state that plainly than overclaim a control this consequential. We are taking design partners now.
