Fern docs monitoring

Draft. This outline will be expanded with verified, platform-specific detail.

How Fern sites typically break

• Navigation is declared in Fern's docs configuration file, and pages removed from the navigation become orphans.
• API reference pages generated from OpenAPI or Fern definitions move when operations are renamed.
• Heading ids are generated from heading text, so rewording a heading changes its anchor.

What Fern catches, and what it misses

• Fern validates the docs configuration when the site is generated; check Fern's docs for what link checking, if any, it performs.
• It misses external links, anchors from other sites, sitemap drift and orphans.

Setting up redirects on Fern

• Redirects are typically declared in the docs configuration; check Fern's docs for the exact syntax.

How PathIntact monitors a Fern site

• PathIntact detects Fern sites from platform-specific markers in the rendered HTML, then reads pages statically with a rendering fallback.
