Version Control Summary Five version-controlled artefact categories: code (Git), data (DVC/LakeFS), models (MLflow/Weights & Biases), configuration (version-controlled YAML/JSON), and the deployment ledger (immutable record of every deployment event). The composite version quad (code version, data version, model version, configuration version) is the version recorded in the AISDP, EU database, and Declaration of Conformity. See for the detailed treatment. Key outputs

• Five artefact categories under version control
• Composite version quad
• Deployment ledger
