 ### 2. Compatibility rules (base type vs candidate type)
 
 | Field base type| Support | How compatibility is checked|
 | - | :-: | - |
-| non-generic interface / abstract class |✅| `baseType.IsAssignableFrom(candidateType)`|
-| generic base type (Unity 2023.2+)|✅| candidate must implement/derive from the same generic definition and match type arguments (supports variance for `in` / `out`) |
-| generic base type (Unity < 2023.2)|⚠️| Unity engine limitations may prevent correct serialization of generic instances|
