Enum Factorization 

pub enum Factorization {
    PerAxis(PerAxisMap<String>),
    Conjunctive(Vec<String>),
    Disjunctive(Vec<String>),
    Opaque(OpaqueReason),
}

Per-coordinate decomposition of a predicate.

comprehension_forms.md §10.9.3 defines the four variants. Opaque carries an OpaqueReason explaining why the analyzer couldn’t decompose further. R5 fires only on PerAxis.

Variants

PerAxis(PerAxisMap<String>)

Predicate factorizes per-axis: p ≡ p_a({a}) && p_b({b}) && … Each entry is the per-axis sub-predicate (as a string, matching the input predicate’s lexical form).

Conjunctive(Vec<String>)

Conjunction of sub-predicates where each may still cross-cut multiple axes.

Disjunctive(Vec<String>)

Disjunction of sub-predicates, each PerAxis or Conjunctive itself (§10.9.5’s disjunction rule).

Opaque(OpaqueReason)

Analyzer can’t structurally decompose. R5 doesn’t fire.
