The working A prototype: use its controls to test the build question.
Let a smart environment act while preserving explanation, authorization, override and recovery.
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.
EXPLAINABLE SMART ENVIRONMENT
Let the smart home explain itself.
Change one exact synthetic state. The modeled action, authorization, override and recovery path recompute—without contacting or controlling a real device.
SIMULATION READY
REQUEST LOW → MODERATE · PURPOSE MODELED FOCUS SUPPORT · WHY THIS MODELED ACTION: CONTINUE
ACTOR SYNTHETIC-PERSON-01 · SCOPE THIS SYNTHETIC CHANGE · CONSENT CONFIRMED
OVERRIDE REMAINS AVAILABLE · STOP OR ASK DOES NOT SILENTLY CONTINUE
ROLLBACK PATH PRESERVED · RECORD WOULD BE REQUIRED BEFORE ANY REAL IMPLEMENTATION
Boundary: This is a fixed synthetic simulation. It does not observe, recognize, infer, authorize, actuate, secure, recover, or certify any real person, home, device, network, preference, disability, safety state, or legal right.
