Контракт
- Deserializing into Option<T> via #[serde(flatten)] where T has all Option fields returns Some(T) with None fields even when no relevant keys are present in JSON
- Deserializing into Option<T> via #[serde(flatten)] where T has required fields without defaults fails inner parsing and returns None when keys are missing
- Branching logic relying on if let Some(...) on flattened Option structs silently executes unexpectedly when inner fields are optional
