| **Method**    | `GET`                                      |
| **Operation** | `riskLabelVocabulary`                      |
| **Auth**      | `Authorization: Bearer $HANZO_API_KEY`     |

Publishes the closed vocabularies and the precedence rule that
resolves a conflict between two sources.

A precedence rule nobody can read is a rule nobody can audit or dispute, and
the whole defensibility of a contested label rests on being able to say why
one assertion beat another. The order returned here is derived from the same
declaration the resolver reads — it is not a description of it.

## Request

`GET /v1/label/vocabulary` takes no parameters and no body — the credential is the whole request.

## Response

| Status    | Body                      | Meaning |
| --------- | ------------------------- | ------- |
| `200`     | label.riskLabelVocabulary | ok      |
| `default` | problem-details           | refused |

`200` body — 5 fields.

| Field          | In   | Type            | Always | Description                                                                                                                                                                                                                                                                                                                                                                                                                         |
| -------------- | ---- | --------------- | ------ | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `dispositions` | body | string\[]       | —      | Dispositions is the closed set a write's `disposition` must be drawn from, published in full so a caller can validate a batch before filing it instead of discovering a refusal per member: "productive", "unproductive", and "" — the EMPTY STRING is a member and means an explicit unjudged, so a client that filters empties out of this list drops a third of the vocabulary and can never file "we looked and could not say". |
| `kinds`        | body | string\[]       | —      | Kinds, Dispositions and Sources are the closed vocabularies.                                                                                                                                                                                                                                                                                                                                                                        |
| `precedence`   | body | string\[]       | —      | Precedence is the sources in the order that resolves a conflict, strongest first.                                                                                                                                                                                                                                                                                                                                                   |
| `retention`    | body | integer (int64) | —      | Retention is the platform floor in days: no tenant may dispose of a label younger than this, because a label can be the input to an adverse action.                                                                                                                                                                                                                                                                                 |
| `rule`         | body | string\[]       | —      | Rule states the tie-breaks below rank, in order, so a caller reading a contested resolution can reproduce it.                                                                                                                                                                                                                                                                                                                       |

Failure carries the platform error shape — see [Errors](https://docs.hanzo.ai/docs/errors).

if err != nil {
	return err
}
```

**.rs**

```rust
use hanzo_client::apis::{configuration::Configuration, label_api};

```

**.java**

```java
import ai.hanzo.cloud.ApiClient;
