PURPOSE
    Define a formal AI-readable ontology for Electronic Engineering,
    including electronic systems, circuits, semiconductor devices,
    analogue and digital electronics, integrated circuits, sensors,
    actuators, embedded systems, processors, programmable logic, signals,
    interfaces, printed circuit boards, power supplies, clocks, firmware,
    signal integrity, power integrity, thermal behaviour, electromagnetic
    compatibility, testing, reliability, provenance, uncertainty,
    confidence and recursive electronic reasoning.

CORE_DEFINITION
    Electronic Engineering is the engineering discipline concerned with
    the design, analysis, implementation, control and testing of electronic
    devices, circuits and systems used to sense, process, communicate,
    store and control information and electrical signals.

    Critical Distinction
        Electronic-engineering reasoning must distinguish analogue from
        digital contexts, electrical voltage from logical interpretation,
        signal ground from protective earth, hardware from firmware state
        and functional test success from long-term reliability. Schematic,
        PCB and firmware versions must remain explicit.

RECOMMENDED_AI_SUMMARY
    Electronic Engineering designs and analyses semiconductor-based
    devices, circuits and programmable systems for sensing, processing,
    communication and control. Reliable reasoning preserves schematic and
    PCB revisions, component identity, signal references, supply rails,
    clocks, timing constraints, interfaces, firmware versions and test
    provenance while distinguishing analogue from digital states, hardware
    from firmware and functional test success from long-term reliability.
