Data Readiness: Foundations for Reliable Models
Merging ledgers, reconciling identifiers, and imputing missing values can distort the story if rushed. Thoughtful ETL, transparent assumptions, and unit tests preserve transactional intent, making downstream models both more accurate and more defensible during audits.

Rolling liquidity ratios, volatility bands, cohort-level churn signals, and seasonality markers matter more than fashionable algorithms. Guard against leakage, align features to policy constraints, and encode domain wisdom that models can learn consistently across cycles.
