Unit 7 Wrap-Up: What Made the Startup Reproducible?

Use your Bringup Verification Record. Respond in 75–125 words or make an equivalent one-minute recording. Use at least two exact labels from your artifact, such as demo_pair.launch.py, /talker_demo, /listener_demo, /robotnix/demo, or topic_name.

1. Which source and runtime records best proved that the launch file created the intended node/topic configuration?
2. What changed in the stale-install failure after you rebuilt the package, and why did editing source alone not change the installed runtime?
3. Which Java/WPILib or physical-robot behavior remains outside the evidence even when the ROS bringup launches and verifies correctly?
