The core ideas, before the 170 chapters
Short, single-concept pages — for the full topic maps with chapter and simulation links, see Research Programs.
The Core Principle
What all five books share: reality selected by stability, not postulated.
Structural Selection
The Ξ-functional formalism (Books I and V).
Structural Stability
The independent stability-criterion formalism (Books II–IV).
Temporal Closure
Gravity as a closure criterion on system history, in one page.
The Reaction–Diffusion Field
The one equation both Books I and II build on.
Unification Map
What's proven, simulated, assumed, conjectured, or open — across all five books, at once.
