Why the receipt matters

Every incumbent sells either raw documents (EDGAR mirrors) or opaque numbers (vendors). Signals Infra sells structured numbers that carry their own receipts — each row has a quote, a source URL, and an accession number, so you can always click through to the primary disclosure.
