A1. Pipeline Execution Logs Immutable records of every CI/CD pipeline run, capturing each discrete stage from data preparation through feature engineering, model training, evaluation, and deployment. Each record includes duration, resource consumption, convergence metrics, random seeds, evaluation results, gate pass/fail decisions, and any exception approvals. Generated automatically at every pipeline run; the pipeline is configured with discrete, auditable stages and each stage emits structured log events on entry, completion, and failure. Responsible party: CI/CD pipeline auto-generates. Technical SME configures the pipeline stages and logging specification. Regulations addressed: Article 12 (record-keeping); Article 17 (QMS); Annex IV(2)(b) (design and development process description). Key outputs

• Per-run structured log with stage-level granularity
• Gate decision records with exception approvals
