+/// Represents the resolved security state for an assistant plugin.
+/// The state intentionally separates two axes:
+/// 1. The audit risk classification, such as Safe, Concerning, or Dangerous.
+/// 2. The availability state imposed by local settings, such as Blocked, Audit Required, or Changed.
+/// This keeps the semantic audit outcome stable even when settings allow or deny usage independently.
