How can I verify if a data item has been altered?

You can use the `verify_item_integrity` tool. By providing the item ID and its current content, the system checks if the content matches the original deterministic hash recorded during transformation.

How do I see the history of a specific piece of data?

Use the `trace_item_lineage` tool with the specific itemId. This will return a chronological list of all transformations that led to that item.

What happens if a model produces a hallucination?

You can use `find_downstream_impact` with the sourceId of the hallucinated item. This identifies all descendant data items that were derived from that specific error.

Data Lineage Tracker provides a verifiable record of how data flows through LLM orchestration pipelines. It maintains a Directed Acyclic Graph (DAG) of transformations, allowing you to audit the history of any data item. Use trace_item_lineage to see the full ancestral path of a specific item, verify_item_integrity to ensure no tampering has occurred, find_downstream_impact to see how a specific error propagates, and register_transformation to log new steps in the lifecycle.
