Feature Pipeline Audit

When to use

Use after feature engineering or pipeline changes.

Inputs

• •Raw data
• •Feature generation cells or functions

Steps

1. •Trace inputs and outputs for each feature step.
2. •Validate alignment of features with targets.
3. •Check for leakage (future data, target contamination).
4. •Confirm stable schema and ordering.

Outputs

• •Feature list with provenance
• •Leakage check result

Failure conditions

• •Leakage risk detected
• •Misalignment between features and labels
