Magnitude Authority Engine

The operators' library on AI answer optimization

How pages get lifted, cited, and linked by AI answer engines — documented by the team at Magnitude that builds and runs three production authority sites. Everything here is a rule we actually operate under, enforced by build gates, not a best-practices listicle.
