## What happened

TEE required for deterministic mode.

## Why it happened

Deterministic verification mode requires TEE but `tee_required` is not set.

## How to fix

Set `tee_required=true` on the job specification.

## Receipt example

```json theme={null}
{
  "code": 1612,
  "slug": "E1612",
  "category": "runner",
  "what": "TEE required for deterministic mode",
  "fix": "Set `tee_required=true` on the job specification.",
  "docs_url": "https://docs.cowboy.inc/errors/E1612"
}
```
