Field notes
Entries pair a belief with a practical counter-rule: the distance item says to include the round-trip light-speed floor in latency budgets before tuning. The catalogue also separates status labels such as “falsehood,” “working belief,” and “unproven,” while its rating system is expressly described as editorial rather than measured. The homepage reports seven beliefs, five still under triage, alongside a coverage graph.
