sec_cik — the SS6 walk
The SEC's own identity register — 49,270 rows binding company names to CIK numbers. Identity is where financial data goes wrong first, so the resolver the star joins on is measured like a first-class source, not treated as a lookup.
One source per sheet; every step CERTIFIED or OWED by BrainTrust Staff, matched against the book’s page.
