| Name | Type | Description |
|---|---|---|
| items | array | Flat node list: tops (priority order) then leaves/providers (alphabetical). Hidden, unlinked, and zero-count nodes omitted. |
| totalEndpointCount | integer | Exact number of catalog-visible endpoints (with `q`: matching the query) — drives the All rail count. |
