# E0001 — ArtifactNotFound

> The .thx artifact file could not be read from disk.

<Warning>E0001: artifact file not found</Warning>

## What happened

The `.thx` file at the specified path does not exist or cannot be read.

## Why

The path does not exist, the file was moved or deleted, or the current user lacks read permission.

## How to fix

1. Check the path: `ls -la <path>`. Confirm the file exists.
2. Check permissions: `stat <path>`. The file must be readable by the current user.
3. If you recently compiled the model, verify `thx.compile()` completed without error and the output path matches the path you are passing to `thrindex run`.
4. If the file is on a network drive, check that the drive is mounted.

## Example

```
E0001: artifact file not found: /tmp/model.thx
Why: the path does not exist or is not readable.
Fix: check the path with `ls /tmp/model.thx` and verify file permissions.
