ai_decide now samples 4 points across the section (start, 1/3, 2/3, end)
instead of just the first 30 + last 20 pages. This gives accurate strategy
detection on large documents where the answer format might be deeper in.
New ai_answer extraction mode:
- Extracts questions from Q&A-format PDFs that have no answer key
- AI picks the correct option from each question's choices
- Generates explanation using document context + medical knowledge
- Useful for PDFs like practice tests where answers were never included
- Available manually and as an ai_decide strategy
Flashcard decks can now be renamed:
- PATCH /flashcards/{deck_id} updates title
- Inline edit on FlashcardsPage with responsive layout (input full-width,
buttons wrap under it so Cancel never overflows the card)
- Title truncates with ellipsis when not editing
Note: generate mode (textbook -> MCQs) is unchanged per user request.

Suspend now pauses the timer instead of letting it run out:
- 'Suspend & Leave' sends suspended=true with time_left to backend
- On resume, backend re-anchors started_at to now with held time_left
- Closing tab without suspending continues to run the timer (unchanged)
Timer-expired auto-submits are marked with expired=1 and excluded from:
- Attempt history (GET /attempts/history)
- Dashboard stats (quiz count, total attempts, average score)
- Attempt list (GET /attempts)
- DDL: ALTER TABLE quiz_attempts ADD COLUMN expired INTEGER DEFAULT 0
Course-quiz decoupling is preserved — these changes only touch
non-course quizzes (Quiz.course_id IS NULL).

Local uploads appeared stuck at 0% because onUploadProgress
doesn't fire granularly on fast local networks or when network
buffering makes the browser report instant completion.
Changes:
- Animated indeterminate progress bar when percent unavailable
- Elapsed seconds counter so user sees activity
- Separate "Uploading" vs "Processing on server" stages
- Hint message about large PDFs taking time

Creators preview courses without enrolling, so markComplete and SCORM
onComplete were hitting the progress endpoint and getting 403. Now
guarded by enrollment check — buttons hidden and callbacks skipped
for non-enrolled users.

SCORM runtime data (bookmarks, scores, lesson position) now saved to
Redis via GET/PUT /courses/{id}/lessons/{id}/scorm/data endpoints.
Data loads before iframe renders and saves on Commit/Finish/Terminate.
90-day TTL on stored data.

SCORM content expects window.API (1.2) or window.API_1484_11 (2004)
on the parent frame. Without it, content fails to initialize.
Implements all 8 required methods for both SCORM versions:
- Initialize/LMSInitialize, Terminate/LMSFinish
- GetValue/LMSGetValue, SetValue/LMSSetValue
- Commit/LMSCommit, error methods
- Auto-marks lesson complete when content reports completion
- Removed iframe sandbox to allow parent frame API access

Embedding:
- Embedding model now configurable via Admin UI (More tab) or LITELLM_EMBEDDING_MODEL env
- Calls LiteLLM proxy directly via httpx (bypasses LiteLLM library param validation)
- Passes dimensions=1024 to proxy; Redis setting overrides env var
- Default model: ge-gemini-embedding-001 (Gemini AI Studio, 1024-dim)
- Test button in admin UI to verify model works
- Fixed vector_service to use httpx + Redis model (was broken with non-prefixed model names)
Polly:
- Global enable/disable toggle in Admin → More settings (stored in Redis)
- /tts/voices filters out polly/* when disabled
- /tts/speak rejects polly requests when disabled
Job cancellation:
- POST /quizzes/job/{job_id}/cancel endpoint

- Settings tab renamed to "More" (heading: More Settings)
- Model row overflow fixed (minWidth: 0 + ellipsis on model_id)
- Embedding model search shows all proxy models (no auto-filter by "embed")

Root cause: setQuizMode(mode) was called BEFORE the network fetch completed.
React immediately re-rendered showing the quiz, but quiz.questions still had
the initial load data (without correct_answer for study mode). On fast desktop
networks the fetch completed before the user could tap; on slower mobile
networks the user tapped an option while correct_answer was still null,
making every answer appear incorrect.
Fix: setQuizMode(mode) moved to AFTER setQuiz(quizRes.data) and
setAttemptId(). The ModeSelectScreen stays visible while data loads,
then switches to the quiz view only when all data (including
correct_answer) is ready.
Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>
Mobile touch fix:
- Added touch-action: manipulation and -webkit-tap-highlight-color: transparent
to .question-card .option CSS — prevents mobile browsers from interfering
with tap events (double-tap zoom, highlight flash, delayed clicks)
Documents hidden for regular users:
- Dashboard: stats card hides Documents count for non-moderators
- Dashboard: document list section completely hidden for non-moderators
- Documents API not called for non-moderators (saves a request)
Timer improvements:
- Custom timer input on ModeSelectScreen — set any number of minutes
for exam mode (overrides the quiz default, or add time to untimed quizzes)
- timeLeft saved to Redis progress every 1.5s (alongside answers, mode, voice)
- On resume: timer restarts from the saved remaining time
- Timer auto-submits when it reaches 0 (already worked, now also works on resume)
- Progress bar shows remaining time relative to what was left at resume
Nextcloud settings — server-side storage:
- GET /auth/me/settings — load user settings from Redis
- PUT /auth/me/settings — save settings to Redis (linked to user_id)
- SettingsPage loads Nextcloud config from server on mount
- Saves to BOTH server (cross-browser persistent) and localStorage (for UploadPage)
- Clear function wipes both server and localStorage
- Switching browsers and logging in restores Nextcloud settings
Also fixed: saved.attemptId → saved.attempt_id in ModeSelectScreen resume check
Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>
Root causes:
1. joinedload(Quiz.questions) was SLOWER (129ms vs 75ms) with the custom
secondary relationship — removed, back to lazy load
2. Redis progress could have stale attempt_id from a completed submission:
GET /attempts/progress now validates the attempt exists and is not completed
before returning; stale entries are auto-deleted
POST /attempts/{id}/submit now clears Redis progress server-side on submit
3. Navbar jobs polling was running every 4s even with no active jobs,
causing unnecessary requests — now polls every 30s when idle,
every 3s when jobs are actively running
Also cleared 3 stale Redis progress entries that were pointing to
already-completed attempts (which caused silent submit failures).

Extraction modes (no restart needed — code ready for next Celery deploy):
- New QuizCreate.extraction_mode field: standard|questions_only|two_step|regex|ai_decide
- extraction_modes.py: independent implementations that don't touch standard path
- questions_only: extract Q+options, correct_answer="PENDING" for manual fill
- two_step: separate answer key section scan + phase1/2/3 matching
- regex: AI detects answer pattern, generates regex, applies to full doc
- ai_decide: AI reads samples from start+end and picks strategy
- DocumentDetailPage: Extraction Mode dropdown with description per mode
- quiz_tasks.py: routes to correct mode, standard path completely unchanged
Database:
- Deleted 11 orphaned questions from PREP 2013 extraction (quiz 12 was already deleted)
- 268 questions remaining (all PREP 2012)
UI fixes:
- Nextcloud section in Settings now only shown to moderators/admins
(regular users can't upload PDFs so they don't need Nextcloud)
- Upload PDF already hidden in navbar for non-moderators (confirmed correct)
- Resume quiz: now async — study mode quiz data loaded BEFORE showing quiz
so correct_answer is available immediately for feedback
- Resume saves and restores voice selection
- voice field added to ProgressSave schema and Redis storage
- Progress save dependency includes selectedVoice
Attempts:
- POST /attempts/start: reuses existing incomplete attempt by default (fresh=false)
Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>
In-progress quizzes section (Quizzes page):
- Shows all incomplete (not submitted) attempts in an amber ⏸ panel
- Each shows quiz title, start date, question count
- Resume button → navigates to quiz (which loads saved answers from Redis)
- Delete button (ConfirmButton) → deletes attempt + clears reminders
Quiz navigation warning:
- beforeunload handler warns when closing browser tab/window mid-quiz
- Leave confirmation modal when navigating away via React Router
(shows "Your progress is saved — resume later" + Stay/Leave buttons)
Quiz progress:
- Scroll on Next/Previous REMOVED per user request — page no longer scrolls
- Progress saved to Redis on every answer/navigation (1.5s debounce)
- Works across browsers, survives logout
- ModeSelectScreen loads saved progress from API and shows Resume button
Attempt management:
- POST /attempts/start now REUSES existing incomplete attempt (no more
creating duplicate incomplete attempts on every quiz start)
Pass fresh=true to force a new attempt
- GET /attempts/in-progress — list incomplete attempts for current user
- DELETE /attempts/{id} — delete attempt + reminders
Cleaned up 10 duplicate incomplete attempts from the database
