David debugged: Investigated class group chat missing from university app header

David launched a parallel investigation:

please launch 6 claude opus 4.7 max agents to go investigate the class chat feature where theres a whatsapp-like groupchat for every course. see if its fully functional and deployed, because i cant see the chat button in the university app home page as an option in the university app header bar. why?

The investigation found that commit d440e2c0f Remove university home chat sidebar had deleted the chat button from UniversityHome.tsx and nothing on main had restored it. The re-introduction code was sitting in uncommitted working tree files.

David caught a concern during the merge:

what exactly are you merging? hoping youre not merging an old version of the product into main?

The chat feature was restored and deployed.
