AI Architecture Guide

Technical blueprint for a resilient, type-safe integration between Service-Alpha and Service-Omega within a Next.js 15 (App Router) environment. This architecture leverages the 2026 Stable SDK standards, focusing on Edge-compatible drivers and zero-latency connection pooling for serverless environments.
