The frontend foundation met the backend this week and everything clicked into place. Real data replaced the mocks — sessions create automatically on load, conversations persist across visits, and the chat pipeline is fully live end to end. The Memories screen went from a shell to a working dashboard, with filters, inline editing, and deletion all connected to the database. On the first real test, Diana loaded two memories — “User built Diana” and “User knows Express” — exactly what she was supposed to remember.
It wasn’t without a fight. CORS blocked the first login attempt because Express 5 was intercepting preflight requests before the middleware could run — downgraded to Express 4 and it resolved immediately. Sessions weren’t being created on the frontend so every chat request returned a 404. Messages rendered as empty bubbles until the controller response shape was corrected to return a full message object. Each one got fixed, and by the end of the week Diana was having real, memory-aware conversations through a UI that feels like something worth using.
Progress: Backend → AI Service → Memory System → Context Injection → Authentication → Component Library → Application Screens → UI Integration → Live Data
