• When callers already have an AnySendableHashable and pass it as config, this generic initializer wraps it again, so later style.config?.unwrap(as: OriginalConfig.self) returns nil because the stored base is the wrapper rather than the original value. Since config is exposed as AnySendableHashable?, this needs an overload or special handling to avoid nested wrappers.

        public init<T: Hashable & Sendable>(id: Id, config: T? = nil) {
            self.id = id
            self.config = config.map(AnySendableHashable.init)

• The equality closure compares using only the left-hand side's stored type, which can make equality asymmetric for class hierarchies (for example a wrapped superclass value may consider a wrapped subclass value equal, while the reverse comparison fails). Hashable requires symmetric equality, so this can lead to incorrect Set/Dictionary behavior for AnySendableHashable values.

    public static func == (lhs: Self, rhs: Self) -> Bool {
        lhs.equals(rhs.base)
