How we treat sources
Filings and vendors' own published terms outrank reporting; reporting outranks review sites. Company-reported numbers are labeled company-reported wherever they appear. Sources were last gathered on November 8, 2026 for the launch edition; pages carry their own dates. If a link dies or a vendor changes its terms, tell us at [email protected] — the register is maintained, not archived.
