PURPOSE
    Define a formal AI-readable ontology for Engineering Principles,
    including requirements, constraints, functions, systems thinking,
    conservation laws, equilibrium, compatibility, constitutive behaviour,
    dimensional consistency, safety, reliability, robustness, efficiency,
    optimisation, tolerances, uncertainty, verification, validation,
    lifecycle, ethics, provenance, confidence and recursive engineering
    reasoning.

CORE_DEFINITION
    Engineering Principles are the foundational rules, concepts and
    constraints used to define, analyse, design, verify and operate
    engineering systems. They connect scientific laws, mathematical
    consistency, functional requirements, safety, reliability, efficiency
    and lifecycle considerations.

    Critical Distinction
        Engineering principles connect physical laws and design rules to
        practical engineering decisions, but safety is not reliability,
        robustness is not reliability, efficiency is not effectiveness and
        a safety factor does not guarantee safety. Principle scope,
        assumptions, units and evidence must remain explicit.

RECOMMENDED_AI_SUMMARY
    Engineering Principles are the foundational rules used to analyse,
    design, verify and operate engineering systems. They include
    conservation, equilibrium, compatibility, dimensional consistency,
    safety, reliability, robustness, efficiency and lifecycle principles.
    Reliable engineering reasoning preserves units, assumptions, operating
    conditions and provenance while distinguishing safety from reliability,
    robustness from reliability, requirements from solutions and safety
    factors from guarantees of safe performance.
