# EXPO-17 — Port display order is cosmetic

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

## The rule

> **Normative.** This is the rule.
>
> 1. A port's declared display order is presentational metadata for whatever draws the node.
>
> 2. No execution, resolution, validation or exposure decision may depend on it, and reordering ports must not change what a workflow does.
