Working theory 2 of 6 · revised October 16, 2026

Where does behavior belong when it lives between things?

What I think right now

In the relationships, modeled directly. Fundamental treats the things on a page as bodies and the behavior as a shared field between them. This site is the working test: every page runs on it.

What would change my mind

Evidence that relational models are consistently harder to reason about than local state for the people who maintain them.

Loose ends

  • How relational behavior should be inspected and debugged.
  • How much of it belongs in native platforms rather than the browser.

The trail

  1. System Fundamental Engine A shared relational field represents bodies, relationships, constraints, and feedback; host adapters connect that model to interfaces and other surfaces.
  2. On the bench Goopy toggle
  3. Public repo Particles ↗

Think I have this wrong? That is the most useful thing you could tell me.
