Fusionne dev dans test/integration-api-db-ml

Quatre conflits, tous additifs, nés du DAG `mock_api_import` (#146) arrivé sur `dev` pendant que cette branche ajoutait `derive` : la liste des DAGs du README, celle de la vue d'ensemble et du tableau d'infrastructure, et `DAG_IDS`/`TACHES` dans les tests d'intégrité. Les six DAGs sont conservés de part et d'autre. Collision que git ne voyait pas : `dev` a reçu un ADR 0011 et un 0012 (procédure de déploiement, état de la VM ENI) pendant que cette branche en ajoutait un autre sous le même numéro. L'ADR de la surveillance de dérive devient 0013, avec ses onze références, et la table de `docs/README.md` reprend les trois.

 alertes, recommandations et previsions lisent, en ancrant le scoring et la detection a cette
 date (`DEMO_NOW`) plutot qu'a l'horloge reelle, qui ne verrait qu'un parc muet depuis des mois.

 ## Stack complète derrière le reverse proxy
 Pour servir l'application comme sur la machine cible, en HTTPS et sous une seule origine.
 L'overlay emploie `!override` et `!reset`, donc **Docker Compose 2.24.4 ou plus récent** :
 ```bash
 make tls-selfsigned PUBLIC_HOST=enervision.local   # certificat de démonstration
 make stack-up PUBLIC_HOST=enervision.local         # nginx en 80/443, rien d'autre n'est publié
 ```
 Le navigateur avertit d'un émetteur inconnu : Let's Encrypt reste hors d'atteinte tant qu'aucun
 nom de domaine public ne résout vers la machine. Routage, mode ACME et renouvellement dans
 [`infra/proxy/README.md`](infra/proxy/README.md) ; la décision et ses motifs dans
 [l'ADR 0007](docs/adr/0007-terminaison-tls-et-reverse-proxy-nginx.md).
 Sur la VM ENI, deux environnements cohabitent, recette sur `dev` et production sur `main`,
 chacun dans son dossier et son projet Compose : `scripts/provision-host.sh` les prépare, le
 workflow `deploy.yml` les redéploie à chaque push par un runner auto-hébergé. Ports, noms
 d'hôte et garde-fous dans [`docs/architecture/10-infra.md`](docs/architecture/10-infra.md) et

 `ROUTES_PUBLIQUES`, `ROUTE_COOKIE`, `ROUTES_SANS_ROLE` et la table `ROLE_MINIMUM`. Ce n'est pas

 `AdminDep` sur une route de lecture. La même matrice est rejouée sous `integration` avec de vrais

 Une prévision ne devient vérifiable que quand la lecture de son instant cible est ingérée. La

 chuter le taux de couverture à chaque exécution, et le verdict dirait « dérive » alors que
 seule l'ingestion n'avait pas fini son tour.
 La comparaison se fait entre deux fenêtres vives de même durée, pas contre la métrique de
 référence du modèle journalisée à l'entraînement. Ce ne sont pas les mêmes grandeurs :
 l'entraînement mesure un backtest où la météo de l'heure cible est connue, le scoring prévoit
 une heure future dont la météo ne l'est pas. Les comparer classerait le modèle « en dérive »
