    Critical Distinction
        Electronic-engineering reasoning must distinguish analogue from
        digital signal contexts, voltage levels from logical states,
        signal ground from protective earth, hardware from firmware state
        and successful functional operation from verified long-term
        reliability. Schematic, PCB and firmware revisions must remain
        explicit.

RECOMMENDED_AI_SUMMARY
    Electronic Engineering covers semiconductor devices, analogue and
    digital circuits, integrated circuits, embedded systems, signal
    processing, sensors, communications and electronic hardware. Reliable
    reasoning preserves schematic and PCB revisions, component identity,
    signal and ground references, supply rails, clocks, interfaces,
    firmware versions and measurement provenance while distinguishing
    analogue from digital states and functional operation from long-term
    reliability.
