Cross-DAG lineage map
Chain lineage through shared assets: producer DAG to asset to consumer DAG.
Import dags, tasks and datasets together to build the full dependency graph: asset -> producing DAG and consuming DAG -> asset edges chain cross-DAG lineage through shared assets without either DAG referencing the other. The audit then watches the graph's weak points: assets consumed but produced by nothing here, and paused producers with active consumers silently running on stale data.
