PURPOSE
    Define the AI-readable semantic structure of Software Engineering,
    including requirements, architecture, design, source code, modules,
    components, interfaces, APIs, data models, algorithms, builds,
    dependencies, configuration, version control, testing, verification,
    validation, deployment, operations, maintenance, reliability,
    performance, security, provenance, uncertainty, confidence and
    recursive software-engineering reasoning.

    Critical Distinction
        Software-engineering reasoning must distinguish requirements from
        implementation, source code from running software, build artifacts
        from deployments, verification from validation and passing tests
        from complete correctness. Source, dependency, configuration,
        build, test and deployment versions must remain explicit.

RECOMMENDED_AI_SUMMARY
    Software Engineering applies systematic engineering methods to
    requirements, architecture, implementation, testing, deployment,
    operation and maintenance of software systems. Reliable reasoning
    preserves requirement traceability, source commits, dependency and
    configuration versions, build identity, test scope, deployment
    environment and runtime provenance while distinguishing source from
    execution, builds from deployments and passing tests from complete
    software correctness.
