The top five leagues are a saturated market. The HNL column is the reason anyone comes here specifically — global platforms cover it thinly, and we treat it as first-class in and out.
| Layer | Source | How | Authority |
|---|---|---|---|
| Clubs, players, IDs | Wikidata (QIDs + multilingual aliases) | SPARQL + entity API | canon |
| Deal resolution | Club official channels | RSS / sitemap poll | canon |
| Claims and rumours | 100 outlets | poll → extraction | claim |
| Journalist wall | Fabrizio Romano + curated X reporters | RSS bridge → source seed → poll | claim |
| Source accuracy | our own ledger | computed on resolution | derived |
One rule holds the product together: every claim carries the URL of the original and we never reproduce the text — headline, one sentence, link out. Only an official club announcement can move a deal to Official; journalists raise confidence, clubs close it.
