# SIFR-PACKAGE-0305: Trust policy names a backend crate that is not a direct dependency.

> Trust policy names a backend crate that is not a direct dependency.

`SIFR-PACKAGE-0305` belongs to the **Package management** diagnostic family. It means: trust policy names a backend crate that is not a direct dependency.

## Why It Happens

Sifr package or workspace metadata violates the package model. Inspect `sifr.toml`, Cargo metadata, source roots, trust policy, archive contents, package selectors, or projection files as named by the diagnostic.

<Info>
  Use `sifr --explain SIFR-PACKAGE-0305` locally to see the renderer's exact message template and any machine-applicable suggestions for the compiler version you are running.

## Erroneous Code

```toml theme={null}
[package]
name = "demo"
```

## How To Fix It

Repair the package manifest, workspace selection, projection files, archive rules, or publish options named by the diagnostic.

## Fixed Code

```toml theme={null}
[package]
name = "demo"
version = "0.1.0"

[sifr]
source-root = "src"
```
