//! [`ScoringPort`] — domain-agnostic aggregation of validator reports
//! into a single [`Score`] for a proposal.
//!
//! Keeping scoring behind a trait lets operators plug their own policy
//! (weighted average, fail-fast on any failed report, learned
//! combinator, …) without touching the core.

    /// pass-fraction scoring) has nothing to discriminate. A judge-aware

    /// judge-free ranking would have picked. `None` means "do not record",
