mountycrawl/db.js

/* Base de référence MountyCrawl — SQLite natif de Node (node:sqlite), toujours
 * zéro dépendance npm. Elle contient les VALEURS DE RÉFÉRENCE du monde partagé :
 * bestiaire, équipement, fourchettes de puissance des potions et parchemins.
 * Chaque spawn/drop du serveur relit la base : une modification (page admin ou
 * n'importe quel éditeur SQLite sur le fichier) est prise en compte à chaud.
 * L'état vivant du monde (trolls, monstres actifs, objets au sol) reste dans
 * world.json — seule la référence vit ici.
 *
 * Au premier démarrage la base est créée et remplie avec les valeurs vanilla
 * (Mountypedia) ; ensuite les lignes existantes ne sont JAMAIS écrasées au
 * démarrage (les retouches survivent aux mises à jour du jeu, et les nouveaux
 * objets/monstres d'une future version sont ajoutés avec INSERT OR IGNORE). */
