## Source (`kind` YAML, verbatim)

```yaml
# yaml-language-server: $schema=../schema/kind.schema.json
# Carries the allow/deny rule set a policy check reads, which load-balancer and network-fabric do not. defaultAction and logging have no default so a rule can flag a filter that never declared its posture.
