docs: make K1 realtime map the primary lidar source

 looks plausible. It also keeps work reusable across Gazebo, Unreal, public
 datasets and future real onboard sensors.
 
+`Dataset` names an immutable experiment input, not one universal point-cloud
+representation. Mission Core keeps two evidence classes:
+
+- public labeled native-scan datasets such as GOOSE and RELLIS qualify
+  algorithms against independent answers;
+- private real-sensor datasets such as `RAVNOVES00` replay the exact K1
+  `lio_pcl`/`lio_pose` representation received during a physical session.
+
+`RAVNOVES00` is therefore a dataset for K1 local-world-model experiments even
+though it must never be relabeled as a native scan. Jobs bind its existing
+session/replay identity and create replaceable derivatives; they do not copy,
+rewrite or mix public points into the K1 source.
