Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implémentation complète du MVP (Minimum Viable Product) : ✅ Module de capture : - Screenshots avec compression WebP (qualité 80%) - Métadonnées des fenêtres actives - Détection d'inactivité (pause après 10min) ✅ Module de stockage : - Base SQLite avec schéma optimisé - Chiffrement AES-256-GCM des données sensibles - Dérivation de clé PBKDF2-HMAC-SHA512 (100k itérations) - Nettoyage automatique après 30 jours ✅ Module d'analyse IA : - Classification heuristique en 5 catégories - Extraction d'entités (projet, outil, langage) - Patterns optimisés pour Development, Meeting, Research, Design ✅ Module de rapport : - Génération de rapports JSON - Timeline d'activités avec statistiques - Export chiffré des données ✅ CLI complète : - activity-tracker start : capture en arrière-plan - activity-tracker report : génération de rapport - activity-tracker stats : statistiques de stockage - activity-tracker cleanup : nettoyage des données - activity-tracker export : export complet 📚 Documentation : - README complet avec exemples d'utilisation - Configuration via settings.toml - Tests unitaires pour chaque module 🔒 Sécurité : - Chiffrement end-to-end des screenshots - Pas de stockage du mot de passe - Protection RGPD avec consentement explicite Conformité avec le design-journal.md pour le MVP. 🤖
