The Ledger · Method
How the Ledger works
When an AI company announces a change to something people build on, we file it: what changed, the date, and a saved copy of the company's own page as proof. Every night we check their channels again for anything new.

How a change is found
Every night we check the companies' channels again for anything new.
Evidence
What an entry needs
Each entry gives the date, what changed in plain words, the company's own words, a link to their page, and a copy of that page saved by us with a fingerprint. If the company later edits or deletes the page, our copy still exists.
Corrections
How a correction is made
Errors are corrected in place with a dated note. The original error remains in the record.

This record starts in January 2026 and does not claim to be complete. It holds what we found and could prove. From 27 July 2026 the check runs every night.
