What is constraint physics?
Constraint physics asks how physical law shapes modelling, continuity and viable observer systems.
Constraint physics names the programme’s future physical-support layer. It asks how physical law, boundary conditions and informational limits shape the possibility of modelling, memory, repair and continuity.
What it is not
It is not a claim that established physics can be casually replaced by metaphor. It is a disciplined question about how physical constraints support or limit the systems that model reality.
Why it belongs in the programme
Observerhood, life and intelligence do not float outside physics. They arise inside a constrained physical world. Constraint physics therefore asks what kinds of physical order make modelling systems possible.
Future direction
In the roadmap, Constraint Physics is treated as a later foundation volume, after the observerhood, living systems and artificial intelligence layers have been made explicit.
