What is Lineage?
Lineage — The traced path of how data and decisions flow and transform as they move through an agentic system.
Lineage is the map of cause and effect inside a system: which inputs produced which outputs, through which steps. When an agent's decision is questioned, lineage is what lets you walk it backward to the source — essential for audit, debugging, and regulated decisions.
Where lineage sits in the stack
In the four-layer architecture of the agentic web, lineage is a Substrate (L1) concept — it the cited foundation every layer grounds in. See the thesis for how the layers compound.
