## Source (`kind` YAML, verbatim)

```yaml
# yaml-language-server: $schema=../schema/kind.schema.json
# A disk with attachment semantics and per-volume performance, unlike object-store which is keyed and shared. encryptionAtRest, redundancy and iops carry no default so capacity and compliance rules can catch a volume that never declared them.
