Operational Recommendations
Three-tier decision policy the OFLC can adopt today, backed by the feature importance and denial-rate segments the model surfaced.
• Publish the model card, including feature list, training window, and test-set metrics, to every reviewer.
• Log every override (human decision ≠ model recommendation) and review monthly for drift.
• Re-train quarterly on the trailing 12 months of adjudicated cases.
• Do not use continent, gender, or any protected-class proxy without disparate-impact testing.
• Historical labels reflect past OFLC decisions — the model will replicate any historical bias unless audited.
• The dataset lacks free-text employer justifications; a real production system should incorporate document review.
• Random oversampling is a weak substitute for SMOTE; a full sklearn pipeline should be the production reference.
