Three coupled fixes from the first manual test pass:
1. Stale signed cookie no longer 500s. `rooms.me()` now raises KeyError
when the participant row is gone (the previous code deref'd None and
threw TypeError, caught by quiz.js's catch-all as 'link expired').
`/api/session/{sid}/me` translates KeyError into 401 + delete_cookie,
so the client falls back to the join form cleanly.
Returning a JSONResponse directly because `raise HTTPException`
discards Response.delete_cookie mutations (FastAPI middleware
composes a fresh response on exception).
2. Reset is now a soft restart from the student's perspective. Before
closing each student WS in `RoomManager.reset`, the server now sends
a `{"type": "session_reset"}` message. The student SPA tears down
local state and re-runs boot(); /me returns 401 (now that the
participant is gone) and the join form renders without the user
having to manually reload. The WS close handler suppresses its
"Disconnected" screen during a reset to avoid a flash.
3. "You" highlight on the student leaderboard is now matched by id, not
by name. `RoomManager.leaderboard()` accepts an optional
`you_student_id` and stamps `is_you: true` on the matching entry only.
No other students' ids leak over the wire (we still don't include
`student_id` in the public top5 payload). quiz.js's renderBoard
prefers `r.is_you` when any row is marked, falling back to name match
for backward compatibility.
41/41 tests pass. Two new tests cover (a) the 401 + cookie-clear path
after reset and (b) `is_you` marking only the requesting student.
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.
