SOURCE REGISTER · VOL. I — 2026
Every named operator.
Every load-bearing number. Sourced.
This book makes specific claims about real people, real businesses, layoffs, lawsuits, revenue, and compensation. The trust contract is therefore higher than for a typical career book. To honor that contract, every numerical or attributed claim is sourced — in the book and here, where you can click through and verify yourself.
CAPTURED AS OF MAY 2026
The three evidence levels
LEVEL 1
Public record
Lawsuits filed in court, SEC filings, government labor data, recorded interviews, podcasts, published case studies, the verified press. When the book cites a revenue figure or quote, the default source category is this one.
LEVEL 2
Operator disclosure
Numbers the operator stated publicly themselves — in their own newsletter, public revenue dashboard, LinkedIn or X post. Self-reported and treated as their own word, dated.
LEVEL 3
Composite illustration
Anonymized or blended scenes built from interviews. Composites open chapters; they do not carry load-bearing claims. They are flagged at first appearance.
