Feuille de route Phase 3 / Roadmap

✅ Whisper.cpp transcription (scaffolded + frontend wired)
virelangues, lis-evalue, G5/G6/G7 lockdown tests use it once the auroch service is up.
✅ Short-answer grader (Flask + Express proxy)
Stub backend ready; Mistral 7B once install_grader.sh runs.
✅ Pen-pal backend (Express router + SQLite)
setup-penpal.sh wires it up on auroch.
⏳ Wire grader into test_runner.html composition grading
After you validate the model on teacher_grader.html.
⏳ MFA + Goodness-of-Pronunciation phoneme scoring
Needs Kaldi install (~3 GB). Next session.
⏳ Wire grader into composition activity inline feedback
Suggestion-only mode; teacher confirms final.
