# Kubernetes ValidatingAdmissionPolicy: "a declarative, in-process alternative to validating
# admission webhooks" that expresses admission rules in CEL ("Validating Admission Policy").
# Per that page it is `admissionregistration.k8s.io/v1`, stable since v1.30, and evaluated
# inside the API server with no webhook server to call. A policy does nothing until a
# ValidatingAdmissionPolicyBinding scopes it and names its validationActions; there is no
# default action, at least one of Deny, Warn or Audit must be declared, and Deny and Warn
# cannot be combined.
