The working A prototype: use its controls to test the build question.
Make environmental assumptions, modeled tradeoffs and unknowns visible without treating a fictional room model as evidence or prescription.
RN conceived the question, structured the evidence boundaries, designed the experience, implemented the prototype and documented its limits.
This independent prototype demonstrates an approach; it is not a deployed client system, professional advice or proof of real-world outcomes.
Work through the controls with a situation of your own rather than the sample values. The tool responds to what you put in, so the useful output comes from real input, and everything is processed in your browser as you go. Any sample content you find already loaded is there to show the shape of a filled-in state, and you can clear it and start again at any point.
The build overview sets out the question, the purpose, the role and the evidence status in one place, and the public record behind it states what changed, what another person can reuse and what supports the system. If you want to judge how far this build should be trusted, the record is the page to read, not this one.

Inspect a Room Model’s Assumptions
Change a fictional room and goal. Watch only the declared model move; no exposure, person, accessibility condition, or effect is measured.

Boundary: This interface exposes assumptions in a fictional room model. It does not measure a room or person, rate evidence, establish an environmental effect, prove causation, diagnose harm, determine accessibility, or prescribe design.
