The division registry defines stable RFFL division codes and how those codes map to names, eras, and ESPN platform IDs.
Current Division Codes
| Code | Canonical name | ESPN divisionId |
|---|
| AA | Aggressive Antics | 0 |
| BB | Beyond Blacked | 1 |
| CC | Combative Chirps | 2 |
| DD | Drunkle Debauchery | 3 |
Naming Eras
| Era | Years | Status |
|---|
| Legacy | 2002-2020 | historical |
| Transition | 2021 | historical |
| Canonical | 2022-present | current |
Rules
| Rule | Meaning |
|---|
| Codes are immutable | Store AA, BB, CC, DD as stable identifiers |
| Names are era-aware | Display names depend on season year |
| ESPN IDs are converted | Convert divisionId 0-3 to RFFL codes |
