Prerequisite Checkpoint: Verify Workspace Readiness

This bridge assumes ROS 2 workspace fundamentals from ros2-for-students.

Your task is to prove the workspace is ready before diagnosing higher layers.

Record:

workspace path:
src path:
expected package:
underlay sourced:
overlay sourced:

Then verify the package is visible from the current shell.

Bridge rule

A package that exists in source is not automatically installed or discoverable. A successful build is not automatically a sourced overlay.

Keep these boundaries separate:

source
→ build result
→ install result
→ shell visibility

If workspace anatomy or colcon is unfamiliar, return to ros2-for-students. This route is a readiness gate for later startup diagnosis.
