The @nestjs/* packages installed from npm (graphql, apollo, mongoose, typeorm) import @nestjs/core and @nestjs/common from where they are installed. When node_modules is linked to another checkout, as in a git worktree that shares the main checkout's node_modules, that is a second copy of every class. Dependency injection then failed (GraphQLModule could not resolve HttpAdapterHost), so every graphql-schema-first spec failed in such a checkout while CI passed. The integration config now dedupes the packages of this repository, so Vite resolves them from the project root whoever imports them. Nothing changes where node_modules is installed in place.
