The moderator-only UI was hidden from moderators. `/auth/me` never returned
`is_moderator`, and the whole frontend decides what to show by reading it —
which is why "Draft with AI" appeared to do nothing: the panel was never
rendered for the person who owns the button.
AI Mode, from the reports alongside it:
- An empty answer was stored and drawn as a blank card. Both the empty reply
and the reply that is empty once an invented citation is deleted are now
refused before anything is written, so the question comes back in the box
with a reason. Old blank cards render an "Ask again" instead of nothing.
- The model narrated its own retrieval — how many sources it had seen, what it
could go and fetch — when asked for more questions than it could cite. It is
now told to name what there is in one sentence and stop.
- A thread took its name from the learner's raw typing, so the rail read "hi,
how do i treat a febrile seizure?". Openers are trimmed, "i" is a capital,
and the cut falls on a word.
- A cited article opened somewhere else. It now gets the same hover card as a
cross-reference in prose — excerpt, new tab, and the pane beside the answer.
- A built session said "questions ready" with no number: the endpoint returns
`count`, not `questions_count`.
And a race the last of those exposed: the guard that stops the transcript
being fetched over an answer that has just arrived was cleared as soon as the
request finished, so whether the exchange survived depended on when React ran
the effect. It now tracks which thread is on screen.
