- /api/payment/orders/{id}/pay requires the short-lived signature that paymentUrl carries;
without it (or with another order's) it is the same 404 as an unknown order
- Session.refresh_token stores the SHA-256 of the token; migration accounts.0007 hashes the
existing rows so tokens clients already hold keep working
- /api/leaderboard requires a token (guests have one); names of children were scrapable
- RAG mock only for `manage.py test`, not any command with an argument named "test"
- tools/loadtest: user factory, load generator, fake GapGPT+Qdrant, with method notes
- security-before-production.md lists only open items; closed ones become a guards table
with the tests that hold them. Comments describe current behaviour, not history

The first assistant round after a restart waited ~6 s before reaching the model on the
live server (later rounds ~1 s); locally a cold 10-ask burst took 7.5 s vs 6.1 s with
this hook (simulated model, 5.2 s). Workers are recycled by max_requests, so the delay
recurred. A failed warm-up is logged and does not stop the worker.

- gunicorn gthread 8 -> 32 threads per worker: each assistant stream holds a thread for
the whole answer; with 3x8, about 20 concurrent asks already queued ordinary page loads
for seconds (up to 23 s at 50 asks locally, 7 s at 20 asks on the live server). With 3x32,
75 concurrent asks kept page loads under 110 ms (laptop, simulated model and Qdrant)
- deploy.sh: new step closes the project dir to other accounts and sets the database and
backups to 0600/0700 on every release; user `nobody` on the shared server could read
db.sqlite3 and every backup
- requirements: python-dotenv 1.2.2, urllib3>=2.8.0 (known CVEs in the installed versions),
gunicorn pinned to the server's version (was only installed by hand)
- security-before-production.md: items 19-23 (file permissions, DEBUG=1 still in the systemd
unit, dependencies, frontend headers, guest AI cap per shared IP) and the reproduced
X-Forwarded-For spoof through the origin IP
- model-prices.md: 0.183 cents per answer from 50 answers in the live load test

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).
