Reproducible

  • • Model version, method, method version and baseline are pinned in the record
  • • Reason codes come only from the factors the model scored
  • • A counterfactual changes mutable features only

Checked, not assumed

  • • Fidelity, stability, sanity and reason-code consistency run in CI
  • • A sample of stored records is recomputed against the pinned model
  • • Post-hoc methods can diverge from the model, so the test is the control

Reused for every duty

  • • One record answers a notice, an access request, an Art. 86 request and an appeal
  • • Appeal outcomes are counted by group and feed fairness monitoring
