Policy engine

Windows, eligibility, fraud thresholds, and legal-basis routing.

The policy engine decides what happens to every return — automatically, and auditably.

Rules

yaml

rule: auto-approve
when:
  - window <= 30d
  - reason != final_sale
  - fraud_score < 0.3
then:
  - approve
  - instant_credit

Every return carries a legal_basis: withdrawal, goodwill_return, warranty, or recall. The engine applies a different rule set per basis.

Fraud-flagged returns are automatically excluded from the fit-graph to prevent data poisoning.
