# R6.f — Numeric bounds apply to numbers only

*GR-VAL (Part I) · level: core · profiles: storage-api · added in 1.0*

## The rule

> **Normative.** This is the rule.
>
> 1. A config value below its schema's `minimum` or above its `maximum` is refused with `R6_CONFIG_INVALID` at `node.{id}.config.{key}`.
>
> 2. Bounds are evaluated only for a value that is a JSON number; a string is never bounds-checked, even when it spells a number.
