Cache Components

Keep the project's caching mode unless migration is requested. Confirm the installed Next.js version and cacheComponents/partialPrefetching configuration before applying these patterns.

Read the relevant guide in node_modules/next/dist/docs/ first (bundled since 16.2; in a monorepo, use the app's own next package). Web paths map to files with numbered folders, so find them by name: .../functions/cacheLife is 01-app/03-api-reference/04-functions/cacheLife.md. Under 01-app/, start with 02-guides/migrating-to-cache-components.md, 01-getting-started/08-caching.md and 02-guides/instant-navigation.md. Error pages under /docs/messages are not bundled; next dev/next build print the fix options inline. Without local docs, use the official caching docs. Exact exports and signatures are also in node_modules/next/cache.d.ts. For static-output and staged-deferral questions in 16.4+, find the installed ensureStatic route-segment reference and navigation/prefetch function references by name.
