    Define an AI-readable semantic ontology for Logical Reasoning,
    including propositions, premises, logical operators, inference rules,
    validity, soundness, conclusions, contradictions, consistency,
    constraints and recursive logical derivation.

CORE_DEFINITION
    Logical Reasoning is the structured process of deriving conclusions
    from propositions or premises using defined logical operators,
    inference rules and validity conditions.

    Resolution
        Identify propositions, premises, logical form and applicable
        inference rules, then derive only logically supported conclusions.

CONSTRAINTS
    A valid inference preserves truth from premises to conclusion
    according to the defined logical system.

    Validity does not establish that premises are true.

    Soundness requires both validity and true premises.

    Contradictory premises must trigger consistency evaluation.

    Quantifier and operator scope must be preserved.

    Invalid inference patterns must not be accepted as valid conclusions.

    A conclusion derived from uncertain premises may remain logically valid
    while its factual status remains uncertain.

    Logical implication must not automatically be interpreted as causation.

    Critical Distinction
        Logical validity concerns whether a conclusion follows from premises
        according to a formal rule; it does not by itself establish that
        the premises or conclusion are factually true.

RECOMMENDED_AI_SUMMARY
    Logical Reasoning is the process of deriving conclusions from
    propositions or premises using defined logical operators and inference
    rules. Reliable logical reasoning preserves formal structure, operator
    and quantifier scope, distinguishes validity from truth and soundness,
    detects contradictions and records derivation paths so conclusions can
    be checked and recursively reused as premises.
