During prerendering, the internal NuxtLink records the path of the page it links to. Custom links without an href and links with a target other than _self behave the same way.
prerender.crawlLinks: false disables this automatic recording and anchor crawling. Routes from prerenderRoutes() and the starter set (the root /, non-dynamic pages, and prerender.routes) are still prerendered.
If prerender.crawlLinks is not set, the crawler follows the hints. This flag only reads prerender.crawlLinks, and this is the default value. nitro.prerender.crawlLinks is no longer used.
A custom link with no anchor, and a link that opens in another tab, record their path while a page is prerendered. crawlLinks set to false turns the hints off.

Run npx skills add coldteadotai/pr-lens, then tell your coding agent: "Diagram the change you just made with PR Lens and attach it to the pull request."
Run npx @coldtea/pr-lens-cli analyze --base origin/main on a branch, then npx @coldtea/pr-lens-cli render .pr-lens/graph.json. Same lenses, your own model key, before the pull request exists

The CLI's render reads .github/pr-lens.yml and applies your renames, exclusions and lane pins at draw time
Set github.comment.collapsed: true in .github/pr-lens.yml to fold the comment behind one View architecture and data flow row. Drawing still runs as before

We've flagged this as a potential contribution without a human behind it. We welcome the thoughtful use of AI tools when contributing to Nuxt, but ask all contributors to follow two core principles:
Never let an LLM speak for you - all comments, issues, and PR descriptions should be written in your own words, reflecting your own understanding.
Never let an LLM think for you - only submit contributions you fully understand and can explain.

Walkthrough
During prerendering, eligible internal NuxtLink paths are added to the prerender route list. The generated hintPrerenderedLinks setting follows the prerender.crawlLinks option, falling back to nitro.prerender.crawlLinks. Tests cover a custom link target that has no local anchor, and the documentation describes the effect of disabling link hints.

Explanation
The description links issue #30870 and explains the change: NuxtLink records target paths during prerendering, the new prerender.crawlLinks: false behaviour, and that prerenderRoutes now lives in its own module. This matches the changeset, which adds prerenderRoutes in a new module and the hint logic in nuxt-link.ts, templates.ts and prerender-hints.ts. The description does not describe every file, such as the docs, fixtures and tests, but it is clearly related and specific.

Add a test for the generated hintPrerenderedLinks value.
The new tests call hintPrerenderedLinksEnabled directly. They do not check the value that the template writes to #build/nuxt.config.mjs. The expression that chooses that input is prerender.crawlLinks ?? nitro.prerender?.crawlLinks. A change to that expression can pass every current test while prerender.crawlLinks: false stops disabling the hints. For example, || in place of ?? turns an explicit false into the fallback value. A literal true in place of the call has the same effect. Add a test that renders the generated config and asserts hintPrerenderedLinks is false when prerender.crawlLinks is false, and true when it is unset.

Nitro leaves crawlLinks unset as off, so hinting every internal link aborted fixture prerenders. Routes from prerenderRoutes() and the initial seed stay eligible when crawling is disabled.
