Point-in-time features
Features are computed strictly from data available at each date to avoid look-ahead leakage.
Solutions
Inspect the machine, not just the output
Walk-forward folds, ensemble weights and disagreement, and estimated-versus-realised samples are all on the record.
Calibration
Probabilities and ranges are calibrated from measured out-of-sample results.
Governance
Immutable, versioned models with accuracy gates and an audit trail on deployments and rollbacks.
- Walk-forward accuracy
- Ensemble weights and disagreement
- Versioned model registry
- Audited promotion and rollback
