| <a id="credentials" /> `credentials?`    | `RequestCredentials`          | Credentials mode for method-call requests. Defaults to `'include'`, which browser apps need for the cookie-based flows (password reset, magic link). Clients configured with token-in-body auth (React Native / Expo) never use cookies, so set `'omit'` there — on Expo Web a credentialed cross-origin request is otherwise blocked by any server answering `Access-Control-Allow-Origin: *`, surfacing as "TypeError: Failed to fetch". | [packages/modelence/src/client/clientConfig.ts:23](https://github.com/modelence/modelence/blob/0e072e44dd157ae8712ae82111cf4aa756460eba/packages/modelence/src/client/clientConfig.ts#L23) |
