// The model is intentionally a subset — we only declare properties we need to inspect
// or modify (ContentRoots, Children tree, ContentRootIndex). Properties like SubPath,
// Pattern, and Depth are preserved via [JsonExtensionData] during round-trip serialization,
// ensuring forward-compatibility as the SDK adds new fields across versions.
