1 · FIXED GROUPS OF SEVEN
The 35 Host Clusters form five permanent cohorts of seven.
Every Vicenio, the Championship returns home

Year 2 protects the continental-cup calendar: Category G stands alone.
Twenty years, organised as five four-year cycles. Each cycle contains one permanent cohort of seven Host Clusters; the same cohort returns every twenty years.
The years and Category assignments in the diagram are illustrative. The permanent cohort compositions and preferred windows are fixed. Within paired Category years, event order remains flexible according to season and geography.

Each cohort returns in the same four-year position every twenty years. Cycle 1: 2035–2038 → 2055–2058 → 2075–2078.
A new draw assigns Categories A–G among those same seven Clusters for the next Vicenio.
* Within its permanent seven-Cluster cohort, the event year follows the Category drawn. Actual hosting remains subject to activation and certification.
