Team codes are stable identifiers used across season files, registries, generated recaps, and lookup workflows.
Code Rules
| Rule | Meaning |
|---|
| Use canonical codes | Public pages should prefer registry-approved team codes |
| Resolve aliases first | ESPN variants and historical abbreviations map through the alias registry |
| Preserve season context | A code can be valid in one season and absent in another |
| Do not guess owner identity | Use the team registry before answering ownership questions |
