# QueuePriorityClass

Where a tenant's work waits relative to others when runners are scarce. Higher classes are admitted first, and work is fair within a class. Running work is never pre-empted. Enterprise sits above every tier sold through the price list.

**Kind:** a string enum, used in responses.

## Values

| Value | Description |
|---|---|
| `"Spare"` | Free: runs when no paid work is waiting, plus a small guaranteed share so it never starves. |
| `"Low"` |  |
| `"Normal"` |  |
| `"High"` |  |
| `"HighestShared"` |  |
| `"Enterprise"` |  |

New values can appear, so treat one you don't know as "something else", not as an error.
