Questions fréquentes

Which YAML spec?

YAML 1.2 via js-yaml - the same parser Kubernetes tooling uses.

Does it preserve comments?

No. YAML comments are stripped on parse - this is a fundamental YAML → JSON limitation, not tool-specific.

What about YAML tags like !!str?

Standard tags are supported. Custom tags are not resolved and will error.
