## The Archive verification object

The outcome of an archive comparison.

| Field | Type | Description |
| --- | --- | --- |
| `status` | enum | `clean`: every range matched. `diverged`: at least one did not. `unanchored`: the comparison could not be trusted or run; see `reason`. Values: `clean`, `diverged`, `unanchored`. |
| `target` | string | The target that ran, normalised (`raw`, `all`, `decode:<name>`, `subgraph:<name>`). |
| `against` | string | The manifest URL, as sent. |
| `signature` | object | Whether the manifest signature verified, and why not when it did not. |
| `coverage` | object | Lowest and highest height compared. Absent when nothing was compared. |
| `ranges` | array of object | One row per compared range. `status` is `match`, `digest-mismatch`, `count-mismatch`, or `missing` when this instance has no rows there. Digests are `null` for an empty range. |
| `reason` | string | Why the result is `unanchored`: `no public key`, the fetch error, the signature failure, or `no digests`. |
