**Motivations:** - Implémenter le workflow complet de démonstration Collatz (commandes.md) - Permettre la reprise après interruption au palier D20 **Evolutions:** - Scripts 01-12 et run-full-workflow alignés sur commandes.md sections 1-10 - collatz_recover_noyau.py : recréation de noyau_post_D20 à partir du CSV candidats - Option --resume-from D20 dans collatz_k_pipeline pour reprendre sans recalculer D18-D19-F15 - Détection automatique : si candidats_D20 existe sans noyau_post_D20, récupération puis poursuite - Filtres --cible=critique et --modulo dans collatz_fusion_pipeline - ROOT par défaut = collatz_k_scripts (plus data/source vide) **Pages affectées:** - .gitignore (__pycache__, out/) - applications/collatz/collatz_k_scripts/*.py - applications/collatz/scripts/*.sh - applications/collatz/scripts/README.md
