Trust & evidence for autonomous machines

The independent trust layer for AI robots.

Lex Prima provides an independent, tamper-evident record of what a robot sensed, decided, and did — making autonomous machines safe, accountable, and insurable.

Request early access

A robot has a brain and a body, and nothing independent in between to prove what happened.

As robots powered by AI move into the physical world they can fail, be manipulated, or act in ways no one can later explain. When something goes wrong the only account of it belongs to the company that built the machine.

Lex Prima creates the other account —
the one nobody involved can quietly revise.

FILE 0001 · INCIDENT RECONSTRUCTION

What happens in the tenth of a second nobody was watching.

  1. T+0.000

    The robot acts

    A pick fails. The arm contacts a person. Whatever happened, it happened in a tenth of a second and nobody was watching.

  2. T+0.004

    We copy, we do not intervene

    Sensor, decision and actuator streams are tapped at the port. The robot’s own control loop is never entered — there is nothing of ours in the path that could have caused this.

  3. T+0.011

    The record is sealed

    Each segment is hashed and signed as it is written. Change one frame after the fact and the chain no longer verifies.

  4. T+later

    Somebody else can check

    An insurer, a regulator or a court re-verifies the signatures against a record the robot’s maker never held. That is the whole product.

SCHEDULE OF EXHIBITS

An evidence and trust layer, independent of the robot’s maker.

Evidence layer

Shipping

Records and cryptographically signs what a robot does, into an independent, tamper-evident record held where its maker cannot reach it.

Available now

EX-01 / SENSOR TAP
Sensor, decision and actuator streams copied at the port. The robot's own control loop is never entered.

Incident forensics

Shipping

When a robot is involved in an incident, produce an independent, court-ready account of what actually happened — a verified timeline and a defensible report.

Available now

EX-02 / RECONSTRUCTION
A verified timeline assembled from signed segments, re-checkable by anyone holding the public key.

Behavioural, privacy & memory validation

In development

Verifies that a robot acts safely, protects sensitive information, and resists tampering with its memory.

Roadmap

EX-03 / VALIDATION
Behaviour checked inside a boundary: does it act safely, protect what it sees, and resist tampering with its own memory.
WHY NOW

Lex Prima · position

Humanoids are deploying. Liability arrives with them.

Robots are moving from cages into shared space at scale. Safety, liability and insurance all require the same thing, and none of them can get it today: a provable record of what a machine did, created and held independently of the company that built it.

  • 01 Independent A neutral third party — not the robot’s maker.
  • 02 Provable Tamper-evident evidence of what actually happened.
  • 03 Safe Validation of behaviour, privacy and memory integrity. In development.
  • 04 Ready Built for the era of humanoid deployment, liability and insurance.
A driverless robotaxi stopped at a night crossing while a pedestrian crosses in front of it EX-05 / SHARED ROADS
The same problem wears different bodies: a pedestrian trusts a car with no one in it.
A driverless truck reversed up to a loading dock while a worker checks a pallet EX-06 / THE DOCK
A driverless truck at the dock. Nobody looks at the empty cab — until something goes wrong.
DISTRIBUTION
A humanoid robot carrying a tote waits at a marked walkway while two workers pass EX-04 / THE FLOOR
Where the evidence is made: shared space, mixed traffic, and nobody finding it remarkable.
  • Robot makers Ship with a record you did not write yourself.
  • Deployers & operators Answer for what happened on your floor.
  • Insurers Price and settle against evidence, not testimony.
  • Safety & compliance Audit behaviour without taking the maker’s word.

Safe. Provable. Insurable.
