The Answer

Formal proof of algorithmic fairness.

Applies Z3 formal verification to AI model decision outputs to prove — or disprove — that protected attributes causally influence outcomes under defined constraints. Produces machine-verifiable fairness certificates for EU AI Act Article 10, Canada's AIDA, and federal AI governance mandates.

§ SPECIFICATION
Input
  • AI model decision log (input features + output decisions)
  • Protected attribute definitions (PIPEDA / AIDA / EU AI Act)
  • Matched cohort definition for causal analysis
Constraints Verified
  • Causal sufficiency — protected attribute is causally sufficient for decision difference
  • Proxy independence — no legitimate feature mediates the causal path
  • Matched cohort validity — identical non-protected features
Output
  • Z3 causal proof or UNSAT certificate
  • Causal pathway from attribute to decision
  • Fairness certificate (machine-verifiable)
  • AIDA / EU AI Act compliance report
