DB:
- quiz_question gains `lang` ('fr' default) and `active` (true default); migration 0002
- only active questions are served to games (pool filter)
History:
- engine writes a game_history row at game end (modes + ranked results), fire-and-forget
- public GET /api/history/:code lists a room's recent games
- lobby shows a "Parties précédentes" collapsible (date, modes, winner/scores)
Back-office:
- create form has a FR/EN language select; lang stored
- per-question active toggle (PATCH /questions/:id) — disable without deleting;
inactive rows dimmed and labelled
- seeds set lang (opentdb=en, manual/pokemon=fr)
Verified e2e: migration applied; game played → /api/history returns it.
