omena-refinement-trait 0.5.0

Interface-only refinement predicate contracts for Omena CSS
Documentation

omena-refinement-trait

Role

omena-refinement-trait is the interface-only cycle breaker for refinement predicates shared by cascade, refinement, and proof layers.

Contract

It defines PropertyIndexV0, RefinementPredicateV0, typed verdicts, provenance, witnesses, and refinement decisions without importing an implementation backend.

Consumers

Cascade, refinement, and proof crates exchange typed decisions through this small dependency.

Boundaries

The crate evaluates no CSS and runs no solver. Adding implementation dependencies here would recreate the cycle it is designed to prevent.

Verification

cargo test --manifest-path rust/Cargo.toml -p omena-refinement-trait
