pnpm add effect @yielded/auth foldkit-remote foldkit-remote-server foldkit-auth

@yielded/auth is a peer, pinned exactly while Yielded is in beta: install @yielded/auth@0.1.0-beta.47, since its latest tag is an older beta. Yielded needs effect 4.1, the minor foldkit 0.170 takes, and each @effect/* release peers on an effect at least its own, so an application pins every Effect package to one release in its package.json to keep one copy of each. With pnpm:

{
  "pnpm": {
    "overrides": {
      "effect": "4.1.0",
      "@effect/platform-browser": "4.1.0",
      "@effect/platform-node": "4.1.0",
      "@effect/platform-node-shared": "4.1.0",
      "@effect/sql-sqlite-node": "4.1.0"
    },
    "peerDependencyRules": {
      "allowedVersions": { "effect": "4.1.0", "@effect/platform-browser": "4.1.0" }
    }
  }
}

npm takes the same pins as overrides, and overrides a package the project depends on itself only where dependencies names that same release, so set those to it too. npx --legacy-peer-deps foldkit-plus setup prints the fields for the project's package manager.
