AI Architecture Guide

This blueprint establishes a type-safe, asynchronous connection between Next.js 15 (React 19) and a Managed Data Layer (Service A and Service B) using the 2026-specification Stable SDKs. It leverages Next.js 15's Async Request APIs and Server Actions to ensure zero-leak client/server boundaries.

10  // Next.js 15 dynamic APIs are now asynchronous
11  const { id } = await params;
12  const query = await searchParams;

14  // Using the 2026 Stable SDK v4.0.0 with native Top-Level Await
