Hi there 👋

It looks like this PR introduces broken links to the docs, please take a moment to fix them before merging:

Broken link	Type	File
/docs/15/app/api-reference/file-conventions/middleware	link	/docs/01-app/02-guides/authentication.mdx
/docs/api-reference/edge	link	/docs/01-app/02-guides/authentication.mdx

Thank you 🙏

	> - Proxy uses the Node.js runtime, check if your Auth library and session management library are compatible. You may need to use [Middleware](/docs/15/app/api-reference/file-conventions/middleware) if your Auth library only supports [Edge Runtime](/docs/api-reference/edge)

The line contains two broken documentation links: one references a non-existent versioned path with /docs/15/ and the other references deprecated middleware instead of proxy, and it also has an incomplete link to the Edge Runtime documentation.

Broken documentation links in authentication guide

What fails: Line 1124 in docs/01-app/02-guides/authentication.mdx contains two incorrect documentation links:

1. [Middleware](/docs/15/app/api-reference/file-conventions/middleware) - references non-existent versioned path and deprecated middleware naming
2. [Edge Runtime](/docs/api-reference/edge) - incomplete path missing /app segment

How to reproduce:

Examine docs/01-app/02-guides/authentication.mdx line 1124

Expected behavior: Links should follow the documentation structure used throughout the codebase:

• Proxy link should be: /docs/app/api-reference/file-conventions/proxy (14 instances of this correct format found across codebase)
• Edge Runtime link should be: /docs/app/api-reference/edge (7 instances found including line 564 in same file)

What was actually happening:

• Version number /15/ only appears in this one broken link (no versioning pattern used elsewhere)
• middleware file convention is deprecated and renamed to proxy per proxy.mdx documentation
• No middleware.mdx file exists in docs/01-app/03-api-reference/03-file-conventions/ directory

Fix applied:

• Changed [Middleware](/docs/15/app/api-reference/file-conventions/middleware) to [Proxy](/docs/app/api-reference/file-conventions/proxy)
• Changed [Edge Runtime](/docs/api-reference/edge) to [Edge Runtime](/docs/app/api-reference/edge)

Both links now match the established documentation patterns used consistently throughout the codebase.
