App Router Audit

Audit Next.js 15 App Router patterns across the codebase.

Scan Areas

1. Server vs Client Components

   • Find all 'use client' directives
   • Verify each is necessary (needs interactivity/hooks/browser APIs)
   • Flag unnecessary Client Components

2. Data Fetching

   • Locate all useEffect with fetch calls → should be Server Components
   • Check fetch() cache configuration
   • Verify no waterfalls (sequential awaits)
