+## Partner collection administration
+
+The Partners list defaults to `name`, `tier`, `sortOrder`, `_status`, `active`, `showOnHomepage`, and `updatedAt`, so editors can review presentation order and visibility without opening every record. `tier` accepts only the numeric values 1, 2, and 3. Within each tier, lower `sortOrder` values render first; tiers remain separate presentation bands.

+The current published local CMS data was verified on 2026-07-31 in this client-review order:

+| 2 | WWK | 1 | 2 |

+| 10 | Deutsche Bank | 3 | 10 |
+| 11 | Bionorica | 3 | 11 |
+| 12 | Primus | 3 | 12 |
+
+Future sponsor order changes are CMS content operations: edit the relevant Partner records' `tier` and `sortOrder` values. They do not require frontend code changes.
