# `shared/singleton-risk`

- Category: **reliability**
- Default severity: **warning**

## Issue

Multiple framework runtimes can split global state, contexts, hooks, or renderers.

## How to fix it

Share stateful framework runtimes as singletons and align their versions.

Suppress or retarget with `rules["shared/singleton-risk"]` set to `"off"` or a severity, see [Suppressions and allowlists](https://mfdoctor.kevinbeier.com/suppressions.md).
