+# Tâches - Correction de la persistance des icônes de tâches
+
+## Contexte
+Les icônes de priorité et de statut "en cours" des tâches générales disparaissent après un rechargement de la page.
+
+## Mise au point actuelle
+Analyse de la structure des données des tâches et de leur persistance.
+
+## Plan Maître
+- [x] Analyser le frontend (`src/pages/Index.tsx`) pour identifier les champs de priorité et de statut.
+- [x] Analyser le backend (`server.js`, `routes/todos.routes.js`) pour vérifier si ces champs sont sauvegardés en base de données.
+- [x] Vérifier le schéma de la base de données et appliquer les migrations.
+- [x] Implémenter les corrections nécessaires (migrations ajoutées à `initDatabase` pour PG et SQLite).
+- [x] Vérifier la cohérence entre le frontend et le backend (types de données).
+- [ ] Vérifier la persistance après rechargement (à valider par l'utilisateur).
+
+## Log de progression
+- Initialisation du fichier `task.md`.
