Two sources

  • • Audit log holds the decision's inputs and outcome
  • • Eval store holds scores and fairness checks
  • • Both are keyed by the same decision ID

Transform

  • • Builder joins evidence for one decision
  • • Technical signals become plain language
  • • Output is scoped to what Article 22 requires

Accountable

  • • Every explanation traces to stored evidence
  • • No new inference is run at explain time
  • • The requester receives a defensible record
