Manage Cypress through the frontend npm lockfile instead of the Nix shell. Approve its install script and align the Oxlint package pair so npm can resolve dependencies without overrides.
Stop invoking the unavailable formatter and remove factory usage for the missing user factory. Give PHPStan workers the same memory allowance as the development shell.
Update the AI guidance for the scaffolded npm application, its actual validation scripts, and its independent runtime boundary. Record the current lack of frontend test tooling without inventing commands.
