+# Session Resume Consolidé — Smart City Digital Twin
+
+## 2026-06-01 (Reprise après crash)
+
+### Objectif
+Reprendre après crash. Commits, sauvegardes, état des lieux infrastructure.
+
+### Actions réalisées
+
+| Action | Statut | Détails |
+|--------|--------|---------|
+| JupyterHub DB_path fix | ✅ | `sqlite:////srv/jupyterhub/jupyterhub.sqlite` (absolute path) |
+| JupyterHub user eric | ✅ | Créé id=2, admin, authorized |
+| JupyterHub spawn timeout | ⚠️ | Augmenté à 120s, mais spawn encore lent |
+| OR mbtiles bounds | ✅ | Metadata bounds → monde, center → Martinique |
+| OR map API | ✅ | center=[-61,14.5], minZoom=0, bounds=Martinique |
+| OR carte tiles | ⚠️ | Tiles Pays-Bas (fond gris Martinique), script génération prêt |
+| Hermes Dashboard | ✅ | WebUI+TUI sur localhost:9119, service systemd auto-boot |
+| Commit/Push | ✅ | `008f167` sur Gitea |
+
+### Problèmes actuels
+- **JupyterHub spawn**: timeout malgré 120s — le singleuser server met longtemps à démarrer
+- **OR carte**: fond gris car mbtiles = tiles Pays-Bas, pas Martinique
+- **Kafka**: restart loop (zookeeper.connect manquant)
+- **Trino**: restart loop (node.environment null)
+- **FROST**: exited 137 (OOM)
+
+### Infrastructure (86 conteneurs)
+- 82 UP, 4 restart loop, 2 exited
+- Traefik, OpenRemote, Grafana, InfluxDB, Simulateur, ODK, MindsDB, MapStore, GeoServer, EMQX, Ditto, ChirpStack, Node-RED, MinIO, Flink, Gitea, LocalAI, PHPIPAM, Honcho = UP ✅
+
+---
+
+## Historique Sessions Précédentes
+
+### 2026-05-29

+- 9 IOTSensor assets créés avec GEO_JSONPoint
+- Mapsettings configuré pour Martinique
+- VRE (JupyterHub + Zeppelin) ajouté au projet
+- Lakehouse stack (Gravitino, Flink, Kafka, Trino, MinIO) déployé
+
+### 2026-05-28
+- ODK Central déployé (https://odk.digitribe.fr)
+- Projet "Smart-City-Martinique" créé dans ODK

+- Grafana dashboard v7 avec données confirmées
+
+### 2026-05-26
+- Reprise après crash — snapshot + resume
+- 61 conteneurs UP
+- Stellio, ThingsBoard, Honcho, FROST, EMQX DOWN
+- Pipeline données confirmé ✅
+
+### 2026-05-23
+- Règle globale Docker: container_name explicite obligatoire
+- Keycloak 24.x: KC_HTTP_RELATIVE_PATH="/auth" requis
+- Simulator OOM (exit 137) — services non essentiels désactivés
+
+### 2026-05-21
+- Ne JAMAIS modifier configs OR par défaut sans permission
+- OR Manager sert UI sur /dashboard/ par défaut, pas /manager/
+
+### 2026-04-29
+- FROST-Server MQTT WebSocket configuré via Traefik
+- mbtiles metadata bounds modifié (Pays-Bas → monde) pour dézoom libre
+
+### 2026-04-24
