Conservation of Interface Irreducibility
A Theory of Persistent Interfaces
Crest is a third place where users encounter the live state of artificial intelligence at the depth a smart friend would explain it. AGORA is the conservation-law paper that names what makes an interface a place: rhythm, friction, and style preserved under user and agent pressure. Crest is the apparatus: a daily issue engine where those laws are observable in the running surface.
The three eigenmodes
Rhythm structures time and attention. Friction shapes effort and decision. Style governs expression and tone. Together they form the irreducibility AGORA names as the conserved property.
