companyfacts — the SS4 walk
The fundamentals backbone: 123.8 million reported facts from the SEC's own XBRL archive — every value a company ever filed, kept as filed. The walk proved the seven-part key duplicate-free across all 123,831,691 rows, found the provider's garbage (period ends in the year 6016 — really), and tagged every flaw with a signed screen instead of a quiet fix. Restatements are never averaged away: the filing date is the truth-clock, so you get each number as it was known, not as it was corrected later.
One source per sheet; every step CERTIFIED or OWED by BrainTrust Staff, matched against the book’s page.
