The working A prototype: use its controls to test the build question.
Build a private sensory and context profile from preferences, sensitivities, goals and past responses.
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.
PRIVATE CONTEXT INSTRUMENT
What works for you?
Recompose one synthetic sensory profile as setting and goal change. The output is a prompt for reflection, not a verdict about a person.

What changed in this setting? Which support should be tested first?
Private by design: this synthetic demonstration persists nothing in the app, sends nothing, and names no person. A profile is context-dependent—not a diagnosis, fixed identity, fitness judgment, or substitute for professional or community-led support.
