What is the Regulatory Bulletin and where does its data come from?

The Bulletin continuously monitors authoritative sources — the Federal Register API first (rules, proposed rules, notices from the FCC, NTIA, and DoD-relevant agencies) — and classifies each item against spectrum bands, services, and topics. Every item carries: a severity level, the affected bands/services, extracted deadlines (comment close, effective dates) with countdowns, a grounded summary, and ALWAYS a citation linking to the primary document. The rule it lives by: it never invents a regulation, a date, or a citation. If it can't cite it, it doesn't say it.
