Enum ModalPreference 

pub enum ModalPreference {
    Default,
    Epistemic,
    Deontic,
}

Controls interpretation of polysemous modals (may, can, could). Used by compile_forest to generate multiple semantic readings.

Semantic Matrix: may: Default=Permission (Deontic, Root) Epistemic=Possibility (Alethic, Epistemic) can: Default=Ability (Alethic, Root) Deontic=Permission (Deontic, Root) could: Default=PastAbility (Alethic, Root) Epistemic=Possibility (Alethic, Epistemic)

Variants

Default

Default readings: may=Permission, can=Ability, could=PastAbility

Epistemic

Epistemic readings: may=Possibility (wide scope), could=Possibility (wide scope)

Deontic

Deontic readings: can=Permission (narrow scope, deontic domain)
