Plain-data structs and the seeded Rng alias from spec §7. Each lives in its own file under src/core/ with unit tests: - Direction, Objective, ObjectiveSpace (with as_minimization negating only Maximize axes) - Evaluation (is_feasible == constraint_violation <= 0.0) - Candidate<D>, Population<D> (concrete, public fields, From<Vec<...>>) - OptimizationResult<D> - type Rng = rand::rngs::StdRng + rng_from_seed, so no public trait is generic over the RNG (spec §2.5) All public types behind #[cfg_attr(feature = "serde", derive(...))] so the optional feature wires up without changing the default surface.
