Autonomous actionAI execution gate
Require renewed human presence before an agent crosses a defined consequence threshold.

Presence / 01 · Human authority
Confirm the expected person before money moves, access is granted or a consequential system acts.
The human boundary
Key adds an independent condition at the moment of consequence. It does not replace identity, policy or the institution responsible for the final decision.
How Key works
The workflow asks one narrow question: is the expected, accountable person physically participating now?
A defined threshold is reached. The request identifies the action, expected person and assurance condition.
The enrolled Key is presented at the physical boundary. No general-purpose network connection is required.
A bounded result establishes whether the required physical participation condition is satisfied.
The institution keeps authority to permit, deny, record or escalate the consequential action.
Where Key matters
Begin with a bounded decision rather than a broad identity transformation.
Autonomous actionRequire renewed human presence before an agent crosses a defined consequence threshold.
Treasury movements, banking changes, procurement and payouts.
Administrative action, recovery, service change and machine authority.
Facilities, vehicles, shared equipment and temporary access.
Protected services, controlled assets and transfer of responsibility.
Key is not another connected endpoint.
A lost Key is not useful to another person.
Designed for a bounded, replaceable lifecycle.
Existing policy remains in control.
System boundary
Key can establish a physical participation condition. Your institution retains identity, mandate, policy, exception handling and the final action.
A purpose-limited result for one defined action and context.
Identity, roles, limits, downstream decisions and the operational record remain under institutional governance.

We will define the physical claim, operating boundary and evidence needed to decide whether an evaluation is justified.
