The desk uses four source classes, in descending order: organizer feeds, team channels, credible reporters with a public track record, and unverified rumor. The desk only publishes a brief or a dossier that is anchored to the strongest source class it has. If the only available source is rumor, the desk labels the brief explicitly and does not promote the rumor to news.
Organizer feeds are first because they are the canonical publisher of the format, the schedule and the bracket. Team channels are second because they are the canonical publisher of the roster. Credible reporters are third because they are an aggregator layer and may paraphrase. Rumor is fourth because the desk has no way to verify it on its own.
The hierarchy is published so that readers can hold the desk to it. If a brief is labelled as a credible reporter or rumor, the desk expects the reader to weight it accordingly. The desk does not promote a brief to a higher source class retroactively.
