# SIFR-PYTRUST-0004: Dynamic Python import requires an explicit trust annotation.

> Dynamic Python import requires an explicit trust annotation.

`SIFR-PYTRUST-0004` belongs to the **Embedded Python trust** diagnostic family. It means: dynamic Python import requires an explicit trust annotation.

## Why It Happens

An embedded Python import or native extension is blocked or untrusted under the project trust policy. Declare trust explicitly for the required Python surface.
