Project Overview We are building an agnostic, headless SvelteKit CMS designed for maximum flexibility. In our architecture, all collections are defined as JSON structures.

Hello My production MERN app needs immediate triage. The most critical blocker is that several React components refuse to refresh their local state, so the UI shows stale data even though the backend is correct. While you are inside the codebase, I also need you to stabilise a few other areas: • JWT sessions are dropping—tokens are set but the user is logged out on page reload, so persistence must be restored. • A handful of Express routes occasionally return different payload shapes for the same request. • MongoDB writes slide past the current validation rules, causing bad documents to sneak in. • Along the way, please clear the minor UI glitches and silence the console warnings we left behind during the last sprint. You will have access to ...
