+## Automatismes
+
+Dans **Réglages → Automatismes**, chaque comportement a son interrupteur :
+
+| Option | Comportement |
+| --- | --- |
+| Ouverture | Démarrer aux horaires et jours prévus. Activée par défaut, comme auparavant. |
+| Début de journée | Au bouton « Arrivé sur site », proposer la dernière tâche de travail de la précédente journée enregistrée, hors repas et transport. |
+| Pause déjeuner | Ouvrir la pause à l'heure habituelle et reprendre la tâche précédente après la durée réglée. Reprendre le type de repas et le restaurant de la précédente journée enregistrée. |
+| Arrivée sur chantier | Lors du repas automatique, transformer un transport initial non renseigné en un transport de 1/5/15/30 minutes, selon l'arrondi, suivi de la tâche précédente. |
+| Fin de demi-journée | À la pause ou à la clôture, remplacer une plage automatique non renseignée par la dernière tâche de travail connue. Conserver tout poste manuel. |
+| Fin de journée | Clôturer à l'heure prévue sans confirmation. |
+
+Les cinq nouvelles options sont désactivées par défaut. Elles sont conservées
+dans les sauvegardes et rétablies lors d'un import en remplacement. L'option
+**Arrivée sur chantier** intervient seulement avec un repas automatique.
+Sans cette estimation de transport, **Fin de demi-journée** peut remplacer le
+transport initial non renseigné par du travail sur toute la plage. Une tâche de
+travail déjà présente suffit : aucun doublon n'est ajouté à la demi-journée.
+
+« Précédente » désigne la dernière journée terminée enregistrée avant la date
+courante, y compris après un week-end. La complétion utilise la dernière tâche
+de travail connue ; sans historique de travail, elle utilise **Travaux sur site**.
+Les postes produits automatiquement portent la mention **Auto**. Les corriger
+les rend manuels et les protège des déductions suivantes. Les saisies anciennes
+sans cette information sont considérées comme manuelles.
+
+Une pause commencée ou corrigée manuellement n'est pas terminée par l'automatisme
+de déjeuner. Un choix manuel du type ou du restaurant est conservé. Une pause
+supprimée n'est pas recréée. Désactiver l'option arrête les transitions suivantes ;
+cela ne supprime pas les postes déjà enregistrés. Une durée de déjeuner nulle
+n'ajoute aucune pause automatique. La durée d'une pause automatique déjà commencée
+est conservée si le réglage change ensuite.
+
+L'app vérifie l'horloge toutes les 30 secondes et au retour à l'écran. Une PWA
+fermée ou suspendue ne peut pas exécuter du code à heure fixe : à la réouverture,
+les étapes manquées sont rattrapées avec leurs horaires prévus, sans écraser une
+action manuelle plus tardive. Les journées déjà clôturées restent intactes et les
+dates entièrement absentes ne sont pas créées. Pour une journée sans intervention,
+activer les options voulues et ouvrir l'app au moins une fois pour cette journée.
+
+Les prolongations et la reprise d'une journée sont respectées. Un démarrage
+manuel laisse au moins une heure avant une clôture automatique. Les transitions
+automatiques sont transactionnelles : une erreur annule toute l'opération et
+des appels simultanés ne créent pas de doublons.
