+Paimon implements [FLIP-314](https://cwiki.apache.org/confluence/spaces/FLINK/pages/255070913/FLIP-314+Support+Customized+Job+Lineage+Listener) to expose lineage information through Flink's native `LineageVertexProvider` interface.

Review Comment:
@JingsongLi I have updated the note section and made it to a warning so that it is more explicit, can you please let me know if this is okay?
It will show as:

Review Comment:
This should probably scope the feature to Flink 2.x. In the Flink 1.x build Paimon only provides compatibility stubs for these lineage interfaces (`paimon-flink1-common/.../LineageVertexProvider` explicitly says the 1.x runtime never calls `getLineageVertex()`), so adding a `JobStatusChangedListener` there will not discover Paimon datasets. Could we mention the minimum Flink version / Flink 2.x requirement near the introduction or configuration section, so 1.x users do not expect this to work?

Review Comment:
This link currently points to FLIP-294 (the catalog modification listener), while the text says FLIP-314. Could we point it to the actual FLIP-314 job lineage listener page so readers land on the lineage proposal instead of a different FLIP?

Review Comment:
This reads as unconditional, but the note below says the Flink planner change needed to extract Paimon datasets from DataStreamScanProvider/DataStreamSinkProvider is still pending. Could we scope this to Flink versions that contain that upstream change, or phrase Table API/SQL lineage as partial until that PR is merged and released? Otherwise users may configure the listener and still get events missing the Paimon datasets.
