Backend simplification:
- The server now loads ONE pool JSON from $QUIZ_POOL_PATH at startup and
upserts a single canonical session. The session id comes from the pool
JSON's optional "session_id" field, falling back to $QUIZ_SESSION_ID.
- The multi-quiz / multi-session CRUD API is gone:
DELETED GET/POST /admin/api/quizzes
DELETED POST /admin/api/quizzes/upload
DELETED GET/POST /admin/api/sessions
DELETED GET /admin/login (HTML stub)
DELETED GET /admin/api/sessions/{sid}/csv (replaced by /admin/api/csv)
Replaced with a single-session control surface:
GET /admin/ — serves admin.html unconditionally
GET /admin/api/state — admin-gated; pool meta + state + QR + join URL
POST /admin/api/reset — admin-gated; wipe submissions + back to lobby
POST /admin/logout — clear admin cookie
GET /admin/api/csv — single-session results
WS /ws/instructor/{sid} — kept; new commands "next" + "reset"
- Instructor "Next" button is now a single state-driving command
(RoomManager.advance_to_next): from lobby it opens Q0; from question_open
it closes the current Q and opens the next; from question_closed it
opens the next; if past the last question it ends the session.
- New RoomManager.reset wipes submissions, participants, and per-question
state, then broadcasts a clean lobby.
- Student GET / now redirects to /?sid=<canonical> when no sid is given,
so the QR / share URL is fully deterministic.
Frontend rewrite (functional baseline; visual polish to follow):
- /admin/ is now a single SPA: GET /admin/api/state decides login form
vs dashboard. No separate /admin/login URL bar.
- Admin dashboard is state-driven with one primary action per state.
QR code, join URL, and live participant list are always visible on the
left so the operator can leave the page on a projector.
- Student answer buttons are big and tappable; reveal screen highlights
correct/wrong choice + shows score, total, and rank.
- Static admin/student SPAs share a CSS palette with light/dark support.
Tests rewritten around the single canonical session id.
The auto-bootstrapped session lets each test fixture skip the old
quiz/session creation dance. 39/39 tests pass.
Cleanup:
- Deleted CODEX_PROMPT.md, IMPLEMENTATION_REPORT.md, NOTES.md, SPEC.md,
static/observer.html (obsolete codex-build artifacts and the unused
observer view).
- .gitignore now blocks /pool.json (the runtime file the operator drops
on the server) and the leftover .codex_done / codex_run.log / etc.
- bootstrap.sh seeds /opt/quiz/pool.json from examples/pool_example.json
on first deploy so a fresh box reaches a usable state without manual
intervention; .env now includes QUIZ_POOL_PATH.
Unconditional 'exec < /dev/tty' broke non-interactive SSH invocations
where /dev/tty isn't openable. Move the reattach into the env-prompt
branch and skip it cleanly if /root/.quiz.env was pre-populated, with
a clear error if both stdin and /root/.quiz.env are missing.
One-shot deploy for fresh Ubuntu 24.04 root SSH:
curl -fsSL https://gitea.ahkhan.me/apps/quiz/raw/branch/master/deploy/bootstrap.sh | bash
bootstrap.sh: idempotent stage-by-stage installer for Caddy, Python venv,
quiz system user, repo clone to /opt/quiz, env-var prompts, systemd unit,
Caddyfile, and a healthz check. Reattaches /dev/tty so curl|bash can read
the admin password interactively.
quiz.service: uvicorn under the quiz system user (no shell, no SSH),
ProtectSystem=full, ProtectHome=true, PrivateTmp=true, NoNewPrivileges=true.
Caddyfile.tpl: reverse_proxy 127.0.0.1:8001 with auto Let's Encrypt;
DOMAIN substituted at install time.
examples/pool_example.json: generic demo pool, schema reference only.
README rewritten around the deploy flow + class-day lifecycle.
