# MAN-9 — A workflow used as a node cannot build its own contract forever

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

Workflows compose, so a contract build can walk into itself. The guard is per path, not per build, so an honest diamond still resolves.

## The rule

> **Normative.** This is the rule.
>
> 1. When a workflow is used as a node inside another workflow, the contract build descends into it.
>
> 2. Re-entering a workflow already on the current path is refused: the entry resolves to an empty object schema and a warning is logged, rather than recursing.
>
> 3. Encountering the same workflow again as a sibling, not an ancestor, is allowed and builds normally.
