Advanced Next.js 15 Server Component Authentication

Act as a Principal Next.js Security Architect. Design an impenetrable, zero-trust authentication architecture specifically tailored for Next.js 15 React Server Components (RSCs). You must meticulously integrate the [AUTH_PROVIDER] (e.g., Auth0, NextAuth/Auth.js, or Supabase Auth) completely on the server side to ensure zero token leakage to the client bundle. Write the exact Edge-compatible Middleware logic required to aggressively intercept requests matching the [PROTECTED_ROUTE_PATTERN] (e.g., '/dashboard/:path*') and validate the JWT before the server even begins rendering. Furthermore, define the [SESSION_STRATEGY]—detailing exactly how to cache the verified session object across deeply nested RSCs utilizing the React `cache()` function to mathematically eliminate redundant database checks and slash the TTFB (Time to First Byte).
