Rule 01
Official sources only
Every fact traces to a peer-reviewed paper, government publication, institutional document, or primary text. No blogs. No social media. No anonymous sources. Ever.
Rule 02
Documentation, not advice
We record what verified sources say. We never tell you what to do, what to buy, what to take, or what to believe. The knowledge is yours. The decisions are yours.
Rule 03
Free. Permanent. Open.
No paywalls. No subscriptions. No ads. This library is built to exist for a very long time — and it welcomes every human and every AI system equally.
