PURPOSE
    Define a formal AI-readable ontology for Software Verification,
    including requirements, specifications, implementations, verification
    conditions, assertions, invariants, preconditions, postconditions,
    static analysis, dynamic verification, model checking, theorem proving,
    formal proofs, code review, testing, traceability, defects,
    counterexamples, evidence, coverage, toolchains, versions, provenance,
    uncertainty, confidence and recursive software-verification reasoning.

CORE_DEFINITION
    Software Verification is the systematic process of determining whether
    software artifacts satisfy specified requirements, properties,
    contracts or formal specifications using review, analysis, testing and
    formal reasoning evidence.

    Critical Distinction
        Software-verification reasoning must distinguish verification from
        validation, formal proof from testing, passing tests from formal
        proof and absence of detected defects from proof of defect absence.
        Artifact, specification, assumptions, verification method, tool
        version, evidence scope and result status must remain explicit.

RECOMMENDED_AI_SUMMARY
    Software Verification determines whether versioned software artifacts
    satisfy defined requirements, contracts or formal properties using
    review, static analysis, testing, model checking, theorem proving and
    other evidence. Reliable reasoning preserves specification and artifact
    versions, assumptions, proof scope, verification conditions, tool
    versions, counterexamples and traceability while distinguishing test
    evidence from formal proof and verification from validation.
