868bd09397 feat(t1-live): examinateur avec interruption probabiliste pilotee backend (Sprint 7a) 
- Session T1 Live : monologue candidat + interruptions pilotees backend (VAD manuel).
- Voix examinateur native Gemini ; le backend decide le timing (tirage probabiliste 0-2, fenetre [25s,75s]), Gemini formule la relance sur signal d'injection (anti-TD-22).
- Injection : activityEnd -> clientContent -> activityStart ; signaux WS interruption_start/end.
- Fin de session : activityEnd final flushe le dernier segment candidat ; relance terminale coupee (audio non renvoye, texte jete) ; seul le texte candidat conserve pour l'evaluation.
- buildT1SystemPrompt : nouvel artefact, regle 7 du T2 NON propagee (questions autorisees).
- Route /t1/live : auth Premium reutilisee, contexte questionnaire dynamique, persistance EO_T1 (sujet_id null), evaluation via correctEO('EO_T1'), phonologie stub /4 (TD-08 gele).
- geminiLive.ts : exports additifs + buildSetupFrame parametrable VAD (T2 inchange).
- gitignore : exclusion des artefacts jetables de test/spike.

7cac057062 feat(eo): align correction EO on 3.6a format + Deepgram token + T1 presentation generation 
Sprint 4a:
- correctEO aligned on CorrectionRapport format (revelation, diagnostic, criteres, conseil_nclc, erreurs_codes)
- nclc_cible parameter (default 9, accepts 9|10)
- Fire-and-forget modele + exercices jobs (same pattern as EE)
- EO-specific DeepSeek prompt (oral transcript tolerance, 4 TCF criteria)
- Gemini transcribeAudio: 30s timeout + 1 retry
- POST /presentations/generate: 5-field questionnaire → DeepSeek generates oral presentation (~220-260 words, NCLC 7-8)
- Migration 006_sprint_4a_eo.sql (documentation only — no audio storage)

Sprint 4b:
- POST /transcriptions/token: Deepgram temporary API key (600s TTL)
- Removed audio storage pipeline (audioStorage.ts, XOR validation, 14MB limit)
- Backend receives transcript text only, no audio files
- TD-10/TD-11 resolved (Sprint 3.6c), TD-16/17/18 resolved (4b cleanup)

UptimeRobot pings GET / every 5 minutes. Previously static response
only kept Node process alive but let Supabase connection pool go cold.
Now executes a lightweight HEAD query (profiles, limit 1) to maintain
DB connection warmth. Always returns 200 with db status field for
observability.
