NEXUS infrastructure · NEXUS agent

AI checks every data point. Experts sign.

The NEXUS agent applies the protocol to all the data, prepares the verification file and flags what needs a human. Reviews in days, never signing in place of the verifier.

Three upright plates: data, the NEXUS agent checking every point, the verifier who signs

02Agentic infrastructure

Three modes. AI operates, it never seals.

  1. Reflex: calculates and checks, deterministic and reproducible code.
  2. Cognitive: prepares and assists, NEXUS agent reviewed by a human.
  3. Governance: validates and seals, verifier and standard-setting bodies.
Three execution modes: reflex, cognitive and governance

03What it does

The heavy lifting, on all the data.

  1. PDD, documents, data: the inputs, pre-reviewed by the agent.
  2. Every data point checked, not a sample.
  3. A verification file, ready for the verifier.
  4. Cases to review, flagged to a person.
The PDD, documents and data go into the NEXUS agent, which hands over a verification file and flags cases to review

04What it never does

The operator, not the authority.

The agent does not validate a project, sign a verification, issue a certificate or ever change a rule. Unit checks, formulas, anti-double counting and version freezing remain verifiable code; decisions remain human.

What the agent may do, separated from what is reserved to deterministic code and human governance

05Verified itself

An object of verification, never the verifier.

  1. Reflex: calculations reproduced identically, for every project.
  2. Cognitive: outputs sampled, against independent human review.
  3. Intensity: calibrated to the project’s uncertainty.
  4. Accredited verifier: also assures the agentic system.

Verifier check: all reflex nodes reproduced, a sample of cognitive nodes reviewed

06Governed like an instrument

Versioned and calibrated like a measuring device.

  1. Model, configuration, tools: part of the measurement system.
  2. Any change: new version, impact assessment, module registry entry.
  3. Every output: carries the version that produced it.
  4. Framework: aligned with ISO/IEC 42001.
Three successive versions, the one in service, an assessed change, an output carrying its version

07Get started

Review cycles in days, not months.

One pilot project is enough to see the agent prepare your first verification file.

+Questions

Does the AI sign certificates?

No. An accredited verifier signs. The agent prepares the evidence and flags what needs a human.

Does it check a sample of the data?

No. It tests every data point against the protocol.

What happens when the AI is unsure?

It flags the case for human review; scientists review flagged cases and sign off.

How is the AI model controlled?

Every output carries the version that produced it, and model changes are handled like recalibrating an instrument, under ISO/IEC 42001.

Can the agent change a rule?

Never. Rules change only through the standard's governance.
