Verifiable human-authorization evidence · for autonomous action

Everyone requires a human
in the loop.
No one can prove it.

Doctrine and law — DoD Directive 3000.09, EU AI Act Article 14, NIST AI RMF — all mandate meaningful human control over autonomous action. None of them provides an artifact that proves it. Today that proof is a log the operator controls: forgeable, backfillable, rubber-stampable. EMILIA Protocol produces an offline-verifiable receipt that a named human authorized the exact action — checkable by a third party without trusting the operator. EP turns human oversight from a policy promise into a cryptographic artifact — no irreversible autonomous action without a verifiable human receipt.

The evidence gap

The hard problem isn't the policy. It's the proof.

When an autonomous system acts, the record that a named, accountable human authorized that exact engagement — at the right scope, currently, under the right authority — is an operator-owned log. After an incident, no inspector general, court, coalition partner, or treaty-verification regime can confirm it without trusting the very operator under review. EMILIA closes exactly that gap.

At the authorization boundary

Not every cycle. The moments that matter.

Per-cycle human approval is incompatible with machine tempo. EMILIA issues receipts at the points where a human grants, scopes, or renews autonomous authority.

Human-in-the-loop
One receipt per action.

A human authorizes each consequential action before it executes. No valid receipt bound to the exact action — the system fails closed. For the highest-consequence decisions where machine tempo allows a human gate.

Human-on-the-loop
One receipt per envelope.

A human authorizes a bounded engagement envelope — effect class, target set, geofence, time window — and retains a halt authority. Autonomy operates only inside the envelope, only while unrevoked and unexpired.

It already does what the mission needs

Shipped mechanisms, mapped to the requirement.

A named, accountable human — not a shared console login
Device-bound signoff (WebAuthn + user verification)
Two-person rule / launch authority
Quorum — m-of-n distinct humans, ordered chain
Authority bounded by rules of engagement
Monotonic delegation constraints + signed ROE / policy reference
The order was current, not a stale standing authorization
Validity window + observed-evidence freshness (fail-closed)
Revoke or halt an autonomous envelope
Revocation + continuous evaluation
Contested, disconnected, classified operations
Fully offline verification; air-gap deployment
No verified human authorization → no effect
Fail-closed enforcement — "no receipt, no execution"
The requirement is already written

Four instruments mandate it. None can prove it.

DoD Directive 3000.09

"Appropriate levels of human judgment over the use of force" — plus auditable, traceable, governable AI.

A receipt proves a named human — or two-person quorum — authorized the exact engagement, within a defined envelope, verifiable offline by an inspector general or coalition partner without trusting the operator. (The primary U.S. defense hook.)

EU AI Act · Article 14

Civilian high-risk AI must be "effectively overseen by natural persons" who can decide not to use it and intervene.

The receipt proves a natural person authorized the action; fail-closed enforcement is the "decide not to use it"; revocation is the stop button. (Civilian tailwind — the Act excludes exclusively military/defense systems; there, DoD 3000.09 governs.)

NIST AI RMF

Documented, auditable human oversight across GOVERN / MAP / MEASURE / MANAGE.

Receipts are the auditable record of who authorized what, under which policy — verifiable, not asserted.

UN CCW · LAWS

The entire debate turns on demonstrating "meaningful human control."

EMILIA turns meaningful human control from doctrine into a cryptographic artifact a third party can check.

Stated plainly

It proves authorization. Not wisdom.

Serious programs will ask exactly where the line is. So we draw it.

Proves

A specific, pinned human — or quorum of distinct humans — authorized this exact action or bounded envelope, at a stated scope, within a validity window, under a referenced authority. Given signature soundness and uncompromised signing keys, the record cannot be forged, replayed, re-targeted, or repudiated, and anyone can verify it offline.

Does not prove

That the human understood the action (a display / WYSIWYS concern), that they were uncoerced, or that the action was lawful or wise. EMILIA is the evidence of authorization — a necessary, not sufficient, condition for meaningful human control. Over-claiming is how accountability tech loses trust.

Make meaningful human control checkable.
