✅ Steps & checkpoints
🗺️ Red pipeline triage
Stages run in order; the first red stage stops the run, and its log names the failing step.
The 2D diagram shows the exact flow, ports and trust boundaries. The 3D scene is a concept view of the same parts; packets travel along the same arrows.
🤔 Think about it
Why should a failed test stop the deploy stage?
🛡️ Safety & cost
Pipelines run in a simulator. No repository or cluster is changed.
🧹 Cleanup
Nothing to clean up.
