From 4b96524964d9c314a094e980771a995dd143189b Mon Sep 17 00:00:00 2001 From: Dom Date: Mon, 19 Jan 2026 15:34:51 +0100 Subject: [PATCH] feat(system): Ajouter gestionnaires backup et version pour Dashboard MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit BackupExporter (backup_exporter.py): - Export complet (workflows, correction packs, coaching sessions, configs) - Export sélectif (workflows only, configs only, etc.) - Export modèles entraînés opt-in (embeddings, FAISS anonymisés) - Sanitisation des configs (masquage des secrets) - Statistiques de backup disponibles VersionManager (version_manager.py): - Suivi de version avec composants - Vérification des mises à jour (manifest local) - Vérification intégrité packages (SHA-256) - Création/restauration de backups pour rollback - Information système complète Ces modules supportent les fonctionnalités Dashboard: - Téléchargement sauvegardes par le client - Mise à jour du système - Rollback en cas de problème Co-Authored-By: Claude Opus 4.5 --- core/system/__init__.py | 61 +++ core/system/api_admin_autoheal.py | 179 +++++++ core/system/api_admin_security.py | 56 ++
