# Attested Computation (§10)

The `computation` field records a deterministic computation that can be re‑run to verify a document’s content. It typically includes a reference to a script or function and its inputs.

## Example

```yaml
computation:
  script: verify_hash.sh
  args: ["{{file}}", "{{expected_hash}}"]
```

When the computation succeeds, the document can be marked `verified: true`.
