Training

Establish and maintain documented provenance and lineage for all training, fine-tuning, and evaluation data used by AI systems, including legal basis, licensing, sensitivity classification, and transformations applied.

Ensure that every model promoted to production is uniquely versioned, traceable to its training data, evaluation results, and approval, and subject to controlled change-management with rollback capability.

Ensure that personal data used in training, fine-tuning, evaluation, and inference is minimized to the data strictly necessary for the stated purpose, processed under a defensible lawful basis, and subject to the rights of affected individuals.
