PURPOSE
    Define a formal AI-readable ontology for Software Engineering,
    including software requirements, architecture, design, source code,
    modules, components, services, interfaces, APIs, data models,
    algorithms, repositories, commits, dependencies, configuration,
    builds, artifacts, testing, verification, validation, releases,
    deployments, runtime environments, monitoring, maintenance,
    reliability, performance, security, provenance, uncertainty,
    confidence and recursive software-engineering reasoning.

CORE_DEFINITION
    Software Engineering is the systematic engineering discipline for
    specifying, designing, implementing, testing, deploying, operating and
    maintaining software systems using controlled processes, versioned
    artifacts and evidence throughout the software lifecycle.

    Critical Distinction
        Software-engineering reasoning must distinguish requirements from
        implementation, source code from runtime software, build artifacts
        from deployments, verification from validation and test success
        from complete correctness. Exact source, dependency, configuration,
        build, test, release and deployment identities must remain explicit.

RECOMMENDED_AI_SUMMARY
    Software Engineering systematically connects requirements,
    architecture, source code, dependencies, builds, tests, releases,
    deployments and operational evidence across the software lifecycle.
    Reliable reasoning preserves exact versions and environments,
    requirement traceability and runtime provenance while distinguishing
