Prerequisite Checkpoint: Pass the Workspace Gate
Close this route with a Workspace Readiness Record that proves:
- the expected source/package location;
- package metadata was inspected;
- a build result exists;
- install output exists where expected;
- the current shell has the intended overlay state;
- package discovery succeeds in the sourced environment.
Then classify the workspace:
READY
PARTIALLY READY
NOT READY
If the workspace is not ready, name the first failed boundary: source, metadata, build, install, or shell visibility.
Do not proceed to launch diagnosis by guessing around a broken workspace baseline.
If these mechanics are not already familiar, return to ros2-for-students. This route verifies readiness rather than teaching workspace fundamentals again.
