/// <summary>
/// Thrown when an operation names a code group that is not present in the cache.

/// <remarks>
/// Distinct from a bare <see cref="KeyNotFoundException"/> so that callers can map "the caller asked for
/// something that is not cached" (a 404) without also catching the dictionary lookups that fail inside the
/// cache's own loading code (a defect, which must surface as a 500 with a traceId rather than being
/// disguised as a not-found answer). It derives from <see cref="KeyNotFoundException"/> so the narrower
/// contract stays source-compatible with any caller still catching the base type.
