Change
Change is what a field transform returns: Keep, Set, or Clear. Its zero value means Keep. Clear empties the callback's own logical value; it does not create an external patch command or durable scalar removal representation.
Value
Value carries an optional logical value. Its zero value is empty. For raw input, empty means omitted and Present(store.Null()) means explicit null. For typed scalars, empty is the portable empty state, not a durable absence encoding. T must follow its own ownership contract; this carrier does not deep-clone arbitrary mutable application values.
