# R6.c — An unknown config key warns but does not block

*GR-VAL (Part I) · level: extended · profiles: storage-api, editor-client · added in 1.0*

## The rule

> **Normative.** This is the rule.
>
> 1. A key in a node's `config` that the node's derived config schema does not declare does not refuse the save.
>
> 2. It yields a warning at `node.{id}.config.{key}` saying the value is ignored at execution, and the workflow is stored.
