Report #4161

[bug\_fix] Data appears stale on refresh; fetch requests return cached data even though the source database has updated

Add \`cache: 'no-store'\` or \`next: \{ revalidate: 0 \}\` to the fetch options, or export \`const dynamic = 'force-dynamic'\` from the page to disable static generation and caching for that route.

Journey Context:
Developer builds a dashboard in a Server Component \(\`app/items/page.tsx\`\) using \`const data = await fetch\('https://api.example.com/items'\)\`. They expect fresh data on every page load. After deploying to Vercel, they update a record in the database via a mutation, then navigate back to the list. The list still shows the old data. Hard-refreshing the browser doesn't help. They check the Network tab and see the fetch request isn't even being made \(or returns 304\). They suspect React Query or SWR caching, but they're using raw fetch. Realizing Next.js extends the native fetch with a persistent Data Cache \(cached across requests and builds by default\), they understand that \`fetch\` responses are cached indefinitely unless configured otherwise. Adding \`\{ cache: 'no-store' \}\` forces Next.js to bypass the Data Cache and always fetch fresh data from the origin on every request.
