//! Semantic assertions for the traefik chart: the pod template ranges
//! `experimental.plugins` and explicitly fails unless each value is an
//! object carrying both `moduleName` and `version`, so those are
//! per-member validator requirements. Values validation and the
//! full-schema pin live in `chart_corpus.rs`.
