Illustrative. Evidence passes four checks; some is turned away before a judgement is formed.

The question

Is the evidence offered about an AI system adequate for the decision it is being used to justify?

Abstract

A connected set of reproducible tools for deployment-conditioned risk analysis, executable regulatory reasoning, evidence adequacy scoring and adversarial stress testing, each deposited on Zenodo with a DOI.

Role

Sole author of each of the four software records, deposited on Zenodo with DOIs in May 2026.

Authors. Roy Saurabh

Trust is not a property of a model. It is a judgement about evidence, made by someone, for a decision.

Four instruments

  1. 01

    Context. CSA-Lite

    Codes public records of real deployments, so that risk is analysed as a function of where and how a system is used.

  2. 02

    Obligation. LEXON-Bench

    Treats regulatory obligations as executable statements that reasoning can be checked against, rather than prose.

  3. 03

    Adequacy. RCEA Passport Engine

    Scores whether audit evidence is adequate for a specific role and decision, with deterministic scoring and full traceability.

  4. 04

    Stress. Provena

    Stress-tests the ways that apparently adequate evidence can be assembled to mislead.
