## Citing other YAML from a comment

- Mark the block you cite with a comment line `# anchor: <name>` (kebab-case, unique in that file). If the block is inside a `|` block scalar, put the marker just above the key, never inside the scalar.
- Cite it as `path.yaml#<name>`, with the path relative to the citing file's directory or to the repo root. Never cite `path.yaml:<line>`, because line numbers go stale on any edit above them.
- `scripts/ci/yaml-citations.sh` enforces this in `ci-manifests-test.yml`: it fails on line-number citations and on citations whose file or anchor does not exist.
