## Definitions

### `at.happyproto.fleet.getHostMix#coverage`

**Type**: `object`

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `of` | `integer` | Yes | A count over twelve of thirty instances is a different claim from a count over thirty. |
| `sharing` | `integer` | Yes |  |

### `at.happyproto.fleet.getHostMix#fact`

**Type**: `object`

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `instances` | `integer` | Yes |  |
| `key` | `string` | Yes |  |
| `value` | `string` | Yes |  |

### `at.happyproto.fleet.getHostMix`

**Type**: `query`

Categorical host facts across the fleet, with consent coverage. Keys whose values vary per instance, or that carry embedded documents, are named but not enumerated. Admin only.

#### Output

**Encoding**: `application/json`

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `coverage` | `ref` → `#coverage` | Yes |  |
| `facts` | `array` | Yes | Only keys whose values repeat across instances. A value seen once per instance is a measurement, not a category. |
| `have` | `integer` | No | History available, when accruing. |
| `need` | `integer` | No | History required, when accruing. |
| `status` | `string` | Yes | Why a figure is absent. Branch on this, never on field presence. |
| `unit` | `string` | No |  |
| `varying` | `array` | Yes | Host keys that are not a mix: values differ per instance, or are JSON documents. Named so a reader knows the key exists, without rendering one row per instance. |

#### Errors

- **AuthRequired**: This endpoint requires an authenticated caller.
- **Forbidden**: The caller is not a HappyProto admin.
- **Upstream**: The telemetry store could not be queried.

### `at.happyproto.fleet.getHostMix#varyingKey`

**Type**: `object`

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `distinctValues` | `integer` | Yes |  |
| `key` | `string` | Yes |  |
