Two-Stage Path
• Recall cheaply narrows the catalog to a small set
• Ranking spends compute only on surviving candidates
• Labels name data assets, not generic API verbs
Compliance Boundary
• Eligibility and suitability are hard filters, not scores
• No protected attributes enter features or ranking
• Every surfaced offer carries an explanation
Measured Lift
• A holdout group never sees personalized offers
• Lift is the treated-minus-control difference
• Outcomes feed back as future training labels
