# Doctrine: core principles

Project principles

Based on “Doctrine (core)”

Academy edition

Engineering serves the support of life, human comfort and a manageable relationship with the environment.

## Light and living systems

Light is considered a factor in vision, biological rhythms and interaction with the environment. Mood, attention and subjective well-being are research topics. Each proposed effect requires defined conditions and a method of measurement.



## Natural dynamics

Dawn, daytime, sunset, night, clouds and shadows provide a starting point for design. Spectrum, intensity, direction and distribution can change. The value of each pattern must be tested for the activity and person.



## Spectrum and electromagnetic environment

The doctrine seeks a suitable spectrum and a controlled electromagnetic environment. This is a project principle. Turning it into a specification requires measurable quantities, operating limits and a review of applicable standards. “Full spectrum” alone does not establish quality or safety.



## AI, person and physician

The person sets goals, reports comfort and retains control. The agent uses permitted data, proposes actions and explains them. A physician participates in clinical tasks and defines medical constraints. Predictive control must account for error and verify outcomes.



## Goals and criteria

The project aims to reduce excessive strain and support sleep, performance and subjective well-being. These outcomes are assessed separately. Improvement in one does not establish improvement in the others.
