//! Semantic assertions for the sealed-secrets chart: the namespaced-roles
//! branch ranges `additionalNamespaces`, which iterates collections and
//! integer counts (Helm's `--set` channel delivers int64, which Go
//! templates range over) but fails on strings and non-integral numbers.
//! Values validation and the full-schema pin live in `chart_corpus.rs`.
