Compare Local Series With ROS Evidence Carefully

A local Java series and a ROS topic can describe the same sensing domain without being the same evidence source.

Compare only what is actually observable:

  • message type and field meaning;
  • units;
  • timestamps or sequence context;
  • value range;
  • publisher/subscriber evidence if available.

Do not infer a Java-to-ROS data path from matching values alone.

Checkpoint

Create a claim matrix with three columns: local Java evidence, ROS runtime evidence, and missing bridge evidence. Mark each claim as supported, unsupported, or unknown.
