+### Shadow CI jobs
+
+CI jobs prefixed with `[shadow]` (e.g., from `ci-namespace-shadow.yml`) are **advisory only** and never gate merge. They run the same test suite on Namespace runners for performance benchmarking. If a shadow job fails, it does not indicate a problem with your PR -- it reflects the state of the Namespace runner migration trial.

 And that's it! Thanks for helping out.
