About a quarter of leafphp.dev pageviews land on old phpDocumentor URLs under /api/classes/classes/*.html and get a 404 (bounce ~0.97). Most of that traffic is Google search for Eloquent/Illuminate classes.

This adds 301s to src/public/_redirects:

• The pages with the most traffic go to the closest docs page: Router to routing, Db-Core to database, App to the intro, Http-Request to request, Date to date, Exception-* to error handling, Aloe-Command to writing commands, Symfony Console Command to MVC console, and Illuminate Eloquent Model/Concerns (HasAttributes, HasRelationships, HasEvents and a few more) to database models.
• Every other Leaf class that still has an API page loses the doubled classes/ segment, so /api/classes/classes/Leaf-Auth.html goes to /api/classes/Leaf-Auth.html.
• Anything else under /api/classes/classes/ goes to /docs/.
• The Illuminate/Symfony names also get a 301 at /api/classes/<name>.html, because those vendor pages aren't in the current build.

Existing /api/classes/*.html pages aren't touched. Netlify serves an existing file before it applies a non-forced rule, and none of these rules are forced.

The doubled path probably comes from relative classes/... links combined with <base href="../"> when a page was reached with a trailing slash. If it keeps showing up, we can regenerate the API docs with absolute links.

Generated by a script, so the list can be rebuilt if the API build changes.
