Prerequisite Checkpoint: Verify Startup From Another View

After launch reports success, verify the runtime independently.

Use a separate shell or supplied evidence to inspect the expected graph:

ros2 node list
ros2 node info <node>
ros2 topic list

The important pattern is:

startup tool says it launched
→ independent runtime evidence says what is actually visible

Do not treat launch console text as a substitute for graph inspection.

Deliverable

Create a Startup Verification Note with:

• launch result;
• independently observed nodes;
• one expected relationship;
• any mismatch;
• the first layer you would inspect if the mismatch persists.

This bridge values independent evidence over optimistic startup output.
