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
- Cancel button on JobsPage for running jobs
- Celery task checks Redis status at each chunk boundary and exits cleanly
- Fixes DB lock on restart caused by cancelled jobs leaving open transactions
Admin UI:
- 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")
- Navbar correctly excludes cancelled/failed jobs from "extracting" count
README:
- Added Rebuild & Restart section with commands
- Updated embedding model reference

Two-phase extraction improvements:
- Auto-detect answer section boundary by scanning in 10-page steps for
'Preferred Response:' — finds exact page where questions end and answers begin
(PREP 2013 answers start at page ~68, not at the end of the file)
- Restrict Phase 1 question chunks to pages BEFORE the answer section
- Extract answer key from answer section in CHUNKS (50 pages each) to handle
large answer sections — accumulates all item→letter mappings
- Previous version used last 40% which missed items 1-~135 for PREP 2013
README: full CLI extraction documentation:
- list-sections: find document and section IDs
- extract <section_id> [--bg] [--title] [--mode] [--user]
- jobs / jobs --user <email>
- Explanation of auto-format detection (inline vs separate answer key)
