David debugged: Extension detection taking 30 seconds on signup completion

After users complained that the post-signup screen was slow to update after installing the Kerra Chrome extension, David commissioned a parallel investigation:

go investigate why it takes like 30 seconds for it to realise ive installed the extension. and further: this is what i see when i finished signing up. actually, initially, the courses werent even there. why??? and why, even now, does it still show the "I couldn't refresh your courses" message

David split the investigation: a dedicated sub-agent traced the extension detection polling mechanism end-to-end (poll interval, detection endpoint, event routing), while the primary agent investigated the university home page loading errors.

Separately, when a candidate workspace click timed out with a LIVE_VALIDATION_TIMEOUT from the extension, David kept probing:

no but that isnt the root cause of the issue. what was the root cause of the issue that caused the extension timeout cause my extension is connected

but again im confused. why was my extension not connected? that doesnt make sense. it seems fine. was it a transient disconnect? for how long?
