psalm-immutable

Declares the expected reply type for a request-style message used with ActorRef::ask(). The nexus-psalm AskReturnTypeProvider reads this attribute at the call site and rewrites the inferred return from Future<R> (where R is unconstrained) to Future<DeclaredReply> — giving the caller full type information at compile time without any runtime cost.

#[ReplyType(Order::class)] final readonly class GetOrder { public function __construct(public string $id) } }

// At the call site: $order = $orders->ask(new GetOrder('42'), Duration::seconds(2))->await(); // ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ // Psalm now infers: Order (not mixed)

The attribute is metadata only — the runtime never inspects it. The plugin's AskReturnTypeProvider does the work at static-analysis time.
