Unit 6 Wrap-Up: Which Topic Evidence Changed the Claim?

Use your Topic Communication Evidence Dossier. Respond in 75–125 words or make an equivalent one-minute recording. Use at least two exact labels from your artifact, such as /scan, sensor_msgs/msg/LaserScan, BEST_EFFORT, RELIABLE, 0.48 m, or 10 Hz.

1. Which topic or message observation gave you the strongest evidence that /scan was more than a visible topic name?
2. What changed when the reliable inspection subscription failed and you switched it to best effort?
3. Which Java-integration or physical-robot claim remains uncertain after the type, message, rate, and QoS evidence are all available?
