# EDGE-6 — An error edge routes a failure instead of raising it

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

## The rule

> **Normative.** This is the rule.
>
> 1. An edge whose source handle ends with `-output-error` is an error edge.
>
> 2. When a node that has one fails, the failure is routed rather than raised: the node's job is recorded as failed and marked as having been routed, the node yields an error payload of `{message, code, node_id, retryable}`, and the run continues along the error edge.
