//! Semantic assertions for the cilium chart: the SPIRE agent and
//! server images are string-or-object type dispatches NESTED under outer
//! enable guards, and the string arm must stay valid with every outer
//! guard ACTIVE. A sparse values document does not exercise this — the
//! historical regression only appeared once the authentication, SPIRE,
//! and install guards were all enabled. Values validation and the
//! full-schema pin live in `chart_corpus.rs`.
