| **Address**   | `https://api.hanzo.ai/v1/o11y/version` |
| **Method**    | `GET`                                  |

Reports the running build: its version, whether an enterprise
edition is present ("N" in this build), and whether first-user setup has
completed.

Open by design; the runtime's own gate is OpenAccess.

## Request

`GET /v1/o11y/version` takes no parameters and no body — the credential is the whole request.

## Response

| Status    | Body                | Meaning           |
| --------- | ------------------- | ----------------- |
| `200`     | o11y.O11yVersionOut | ok                |
| `202`     | Approval            | held for approval |
| `default` | problem-details     | refused           |

`200` body — 3 fields.

| Field            | In   | Type    | Always | Description                                                          |
| ---------------- | ---- | ------- | ------ | -------------------------------------------------------------------- |
| `ee`             | body | string  | —      | EE says whether an enterprise edition is present; "N" in this build. |
| `setupCompleted` | body | boolean | —      | SetupCompleted says whether the first user has been created.         |
| `version`        | body | string  | —      | Version is the build version.                                        |
