Found in a deeper pass over what the frontend's flow actually touches:
- Nothing in the app ever wrote StreakRecord: "days in a row" was 0 forever
for every real user. Answers and lesson/island completions now record the
day (Tehran time); a broken chain shows 0. A streak error never fails the
answer itself.
- /api/leaderboard only changed when someone ran rebuild_leaderboard by
hand. It is now computed live (60s cache); weekly counts island XP too.
- gunicorn ran 3 sync workers with a 30s timeout, so every "ask Pi" stream
pinned a whole worker (~10s, GapGPT buffers the answer) and three at once
queued the entire API. gunicorn.conf.py (read automatically from the
working directory) switches to gthread, 8 threads, 120s timeout.
- Every /api/ response now says Cache-Control: private, no-store, so turning
on caching in the ArvanCloud panel can never serve one student another's data.
- /api/user/summary named no active plan ever ("subscription app not
implemented yet" had long stopped being true).
