Enum EpistemicComponentMergeReason 

pub enum EpistemicComponentMergeReason {
    SharedHeadPredicate {
        predicate: String,
    },
    DerivedPredicate {
        predicate: String,
    },
    SharedModalPredicate {
        predicate: String,
    },
    Constraint {
        predicates: Vec<String>,
    },
}

Reason that two source rules were coalesced into the same dependency component.

These reasons make the split planner’s structural decisions explainable: a caller can read, for every component, why its rules could not be solved independently of one another through split-component diagnostics.

Variants

SharedHeadPredicate

Two rules share the same head predicate, so they jointly define one derived relation and must be solved together.

Fields

predicate: String

Head predicate defined by both rules.

DerivedPredicate

One rule’s body consumes a predicate that another rule derives in its head (an ordinary/negated derived dependency).

Fields

predicate: String

Head predicate produced by the producer rule and consumed by the consumer rule body.

SharedModalPredicate

Two rules reference the same epistemic (modal) predicate, so their world-view acceptance is mutually dependent.

Fields

predicate: String

Epistemic predicate referenced by both rules, with arity.

Constraint

An integrity constraint mentions head predicates owned by both rules, so the constraint coalesces exactly those components.

Fields

predicates: Vec<String>

Constraint-mentioned head predicates that forced the coalesce.
