Governance of AI systems requires more than logging outputs. It requires tracing the decisions that shaped those outputs — what training data was selected, which model version was approved, what thresholds were set, and who authorized each change.
AI decision lineage connects these governance events to the artifacts they reference. When a dataset is certified, the certification decision is recorded. When a model is approved for deployment, the approval event links back to the certified datasets in the training record.
CertifiedData emits decision lineage records for every certification event, linking the certificate to the DecisionLedger — a tamper-evident log of AI governance decisions.
What AI decision lineage records
Decision lineage is a structured record of every governance-relevant decision in the AI lifecycle. Unlike raw system logs, lineage records are explicitly linked to the artifacts they describe — providing a navigable graph of how decisions and artifacts relate.
This graph allows auditors, model owners, and compliance teams to trace any artifact back to the decisions that produced it, and any decision forward to the artifacts it affected.
- Training data selection and certification decisions
- Model evaluation approval events
- Deployment authorization records
- Threshold and configuration change decisions
- Certificate issuance and revocation events
- Human review and sign-off records
Linking decisions to certified artifacts
The power of decision lineage comes from linking events to specific artifact versions. A training data selection decision references the exact dataset certificate ID. A model approval decision references the evaluation results and training data certificates.
This linking means that if a question is raised about a model — why was it trained this way, what data was used — the answer is traceable through the lineage graph to specific certified artifacts.
CertifiedData and DecisionLedger integration
CertifiedData automatically emits a lineage record to DecisionLedger for every certificate issuance. The record includes the certificate ID, artifact hash, signing key ID, and decision outcome.
This creates a publicly auditable transparency log of certification decisions — verifiable independently of the CertifiedData platform.
- Automatic lineage emission on certification
- Public decision log for enterprise and free-tier certificates
- Certificate ID linked to DecisionLedger decision ID
- Tamper-evident checkpoint anchoring
Compliance applications
The EU AI Act Article 12 requires that high-risk AI systems maintain logs enabling human oversight and ex-post evaluation. Decision lineage records satisfy this requirement by creating structured, navigable links between governance decisions and the artifacts they reference.
Organizations can export lineage records as part of conformity documentation, model risk management reports, or regulatory submissions.
Frequently asked questions
What is the difference between AI decision lineage and an audit log?
An audit log captures system events chronologically. AI decision lineage adds explicit links between decisions and artifacts — allowing governance teams to navigate from an artifact to the decisions that produced it, or from a decision to all the artifacts it affected.
How does CertifiedData emit decision lineage records?
Every CertifiedData certificate issuance automatically creates a signed record in the DecisionLedger. The record includes the certificate ID, artifact fingerprint, and governance metadata. Enterprise and free-tier certificates default to public transparency mode.
Can decision lineage records be used for EU AI Act compliance?
Yes. Decision lineage records provide the structured, machine-readable documentation needed for EU AI Act Article 12 compliance — linking training data certification decisions to specific artifact records with full provenance.
