 - Les versions ci-dessous ont été reconstituées à partir des JAR archivés, des packs locaux et du code source actuel. Les dates n'étant pas enregistrées de manière fiable, elles ne sont pas inventées.

 - conserve les données Red-Stoner v3, Only Fun v2 et Sanctuary v11 ; seul le protocole réseau Red-Stoner passe de 5 à 6, sans nouveau monde ni réinitialisation des sauvegardes.

+- corrige la hauteur trop grave et la vitesse trop lente du disque blanc en compensant la cadence du flux AAC YouTube par un facteur OpenAL exact de `4/3` ;
+- réapplique cette hauteur pendant toute la lecture afin qu’aucune mise à jour du canal audio ne la ramène à la valeur ralentie ;
+- valide la correction sur le lien signalé en comparant vingt secondes décodées par Lavaplayer au flux AAC direct, puis conserve les tests PCM 48 kHz et de niveau sonore ;
+- conserve les données Ambiance v2, le protocole réseau 6, les IDs et les sauvegardes existantes ;
+- distribue Ambiance `0.0.0-alpha.20` dans Packwiz et le `.mrpack` partagé client/serveur, sans exiger de nouveau monde ni réinitialiser les sauvegardes.

 La migration [CANA-01 à CANA-09](CANAPLIA.md) porte Canaplia vers Minecraft 26.2. It's Alive **`0.0.0-alpha.35`** enregistre les seize familles, les découvertes, hybridations, résines, effets serveur et le Livre interdit personnel, partageable temporairement sur un pupitre. Ambiance **`0.0.0-alpha.14`** compose les profils visuels bornés avec ses réglages d'accessibilité, et Only Fun **`0.0.0-alpha.21`** exclut explicitement Canaplia et les raccourcis de progression du Shop.
 
-L’alpha.217 ajoute le terminal de stockage Red-Stoner : cette demi-dalle verticale se fixe sur un coffre, un coffre piégé ou un baril et donne accès, par pages défilantes de 54 types, à un réseau contigu borné à 128 conteneurs chargés. Les retraits et dépôts sont validés par le serveur, les composants d’items restent strictement séparés et le terminal endgame est exclu du Shop, du Black Market et des récompenses Only Fun.

+L’alpha.217 corrige définitivement la hauteur trop grave du disque blanc : la cadence AAC mesurée sur la vidéo signalée est compensée par un facteur OpenAL exact de 4/3, maintenu pendant toute la lecture.
 
 L’alpha.216 corrige la lecture lente et dégradée du disque blanc : les quatre tampons PCM initiaux de Minecraft sont maintenant remplis continûment à 48 kHz, avec une vitesse OpenAL normale, au lieu d’être majoritairement complétés par du silence. Les packs Modrinth, Prism et Packwiz sont mis à jour sans exiger de nouveau monde ni réinitialiser les sauvegardes.
