Unit 6 Wrap-Up: What Did the Graph Actually Show?

Use your ROS Graph Evidence Record. Respond in 75–125 words or make an equivalent one-minute recording. Use at least two exact labels from your artifact, such as ROS_DISTRO=jazzy, /sensor_bridge, /motor_guard, /scan, /cmd_vel, or caution_distance_m.

1. Which shell and graph observations gave you the strongest evidence that the Jazzy runtime was ready to inspect?
2. What changed after the deliberate shell reset, and why was sourcing the environment the correct repair?
3. Which message-delivery or physical-behavior claim remains uncertain after all Week 11 graph and parameter evidence is available?
