The limits, stated
Arthur does not make decisions, and it does not act autonomously. It does not generate investigative conclusions from a language model. It does not score people behind a model no one can inspect.
The officer decides. Arthur shows the working.
Oversight
An independent board, with the standing to say no.
Lockhouse is overseen by an independent Ethics and Integrity Board whose members have between them run Britain's intelligence, counter-terrorism and Home Office teams. Its purpose is challenge rather than endorsement, and it is constituted so that challenge carries weight.
The same people advise on how capability is developed and where it should not go.

Risk
The risks that decide whether a deployment holds.
These recur wherever AI has been introduced into policing. Each is a shared obligation, not a clause to transfer.
01 · Vendor lock-in
Your data and your exit stay yours
Open interfaces, documented schemas and no dependency that makes leaving impractical. A flexible ecosystem is a continuity requirement, not a preference.
02 · Super users
Limits understood by those who explain them
Super users and managers are trained on what the system cannot do, so that understanding reaches every user, and the people who receive the outputs.
03 · Tolerance for error
Agreed before go-live, against a human baseline
Error tolerance is set explicitly for each use, and compared with the existing manual process rather than with perfection.
04 · Data
The constraint on what can be asked
Data answers the question, and also determines which questions can be asked at all. Quality and coverage are assessed before capability is promised.
Standards
Clearance, conduct and commitments.
Staff hold security clearances at classified levels, appropriate to the environments in which Arthur is deployed. Handling conditions travel with the data, and with the people who see it.
Lockhouse is a signatory to the Armed Forces Covenant.
Questions of governance are best answered in person, and in detail.
