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.
