PURPOSE
    Define a formal AI-readable ontology for the Software Lifecycle,
    including conception, requirements, planning, architecture, design,
    implementation, integration, verification, validation, testing,
    release, deployment, operation, monitoring, maintenance, evolution,
    retirement, lifecycle models, baselines, versions, changes, approvals,
    artifacts, traceability, risks, quality evidence, provenance,
    uncertainty, confidence and recursive software-lifecycle reasoning.

CORE_DEFINITION
    The Software Lifecycle is the complete sequence of controlled states,
    activities, artifacts and transitions through which a software system
    progresses from initial need and requirements through design,
    implementation, verification, deployment, operation, maintenance,
    evolution and eventual retirement.

    Critical Distinction
        Software-lifecycle reasoning must distinguish lifecycle stages from
        necessarily sequential phases, releases from deployments,
        deployments from operational states, development completion from
        lifecycle completion and planned retirement from actual retirement.
        Lifecycle model, artifact versions, baselines, transition criteria,
        approvals and evidence must remain explicit.

RECOMMENDED_AI_SUMMARY
    The Software Lifecycle describes the controlled evolution of software
    from stakeholder need and requirements through architecture, design,
    implementation, verification, release, deployment, operation,
    maintenance and retirement. Reliable reasoning preserves lifecycle
    model, artifact versions, baselines, changes, approvals and operational
    evidence while distinguishing releases from deployments, deployments
    from operation and development completion from the end of the software
    lifecycle.
