AgentLineage

Why this is canonical

'Lineage' is a term of art in data engineering (data lineage, model lineage) that is now migrating to agent systems as auditability requirements intensify. Pairing it with 'agent' on .ai places this coordinate precisely at the emerging intersection of AI governance and chain-of-custody requirements.

Where it fits

A few directions this coordinate opens —

Regulated industry compliance
Demonstrating the full lineage of an agent's decision — which data, which model version, which tool call — to satisfy audit requirements.
Financial services, healthcare AI, legal-tech platforms
Model and data governance
Tracking the upstream lineage of model weights, training data, and fine-tuning runs that produced an agent's behavior.
MLOps vendors, enterprise AI governance platforms
