PURPOSE
    Define a formal AI-readable ontology for Processors, including
    instruction-set architectures, processor cores, pipelines, fetch,
    decode, execution, registers, arithmetic logic units, floating-point
    units, branch prediction, caches, memory interfaces, interrupts,
    privilege levels, clocks, parallelism, performance, power, thermal
    behaviour, faults, security features, testing, provenance, uncertainty,
    confidence and recursive processor reasoning.

CORE_DEFINITION
    A Processor is a programmable computing device that executes
    instructions defined by an instruction-set architecture using
    microarchitectural resources such as processor cores, pipelines,
    registers, execution units, caches and control logic.

    Critical Distinction
        Processor reasoning must distinguish processor hardware from the
        ISA it implements, processor packages from individual cores, core
        count from realised parallel speedup, clock frequency from measured
        performance and thermal-design ratings from actual power
        consumption. Performance evidence must retain workload and thermal
        context.

RECOMMENDED_AI_SUMMARY
    A Processor executes instructions defined by an instruction-set
    architecture using cores, pipelines, registers, execution units,
    branch predictors and caches. Reliable reasoning preserves processor
    model and revision, ISA and extensions, core and cache configuration,
    workload, clock, IPC, CPI, power and thermal state while distinguishing
    hardware frequency and core count from realised application
    performance.
