Intended Use

- Static QA generation for financial reasoning tasks
- Dynamic five-stage pipeline evaluation with realistic market replay
- Stress testing under historical crisis regimes

Point-in-Time (PiT) Constraint
All features strictly respect temporal integrity — no look-ahead bias. Any derived feature uses only information available at or before the corresponding date.
