# DYN-6 — Dynamic ports carry no exposure state and are not addressable from outside

*GR-DYN (Part I) · level: extended · profiles: storage-api, runtime · added in 1.0*

Exposure is a property of a port the processor declares. A dynamic port is not declared, so there is nothing to hide and nothing to strip, and for the same reason nothing an outside caller can name.

## The rule

> **Normative.** This is the rule.
>
> 1. A dynamic port has no exposure: it is always wireable, its value is never stripped from a node's output, and edge validation raises no exposure objection against it.
>
> 2. For the same reason a dynamic port is not addressable at the workflow boundary: a launch-input manifest entry naming one is refused, because the port is not declared by the node's processor.
