+- transforme le panneau de trophées en plaque verticale de chêne, corrige le texte auparavant masqué et utilise les quatre lignes pour le titre paginé ainsi que les trois places du podium ;
+- permet de passer à la page suivante d’un clic droit et de revenir à la précédente avec `Maj` + clic droit, sans changer les IDs, les sauvegardes Red-Stoner v4 ni le protocole réseau 7.
+- garantit sur chaque niveau de la Backroom un coffre par cellule de 3 × 3 chunks dans les nouveaux chunks, au lieu d’un coffre aléatoire réparti entre les cinq niveaux ;
+- resserre aussi la grille des lits de sortie de 10 × 10 à 3 × 3 chunks sur chacun des cinq niveaux afin qu’ils soient réellement trouvables ;
+- ne change ni le butin ordinaire des coffres, ni les données Sanctuary v15, ni le protocole réseau 24 ; les nouveaux coffres et lits apparaissent dans les chunks qui n’ont pas encore été générés.

+## `26.2.0-alpha.230`
+
+Modules modifiés : **Sanctuary `0.0.0-alpha.136`** et **Red-Stoner `0.0.0-alpha.17`**.
+
+- attribue les demandes de quêtes personnalisées terminées à leur preneur directement sur le panneau et dans les détails au clic, avec son pseudonyme et sa couleur conservés ;
+- répartit les lits de sortie rares sur chacun des cinq niveaux de la Backroom, avec exactement un lit par cellule de 10 × 10 chunks et par niveau dans les nouveaux chunks ;
+- conserve les IDs, les données Sanctuary v14 et le protocole réseau 24 ; les chunks Backroom déjà générés restent inchangés.
+- ajoute l’API publique Sanctuary de métriques et de classements persistants par UUID, avec import monotone des statistiques vanilla, podium borné et exclusion des actions créatives, spectateur ou simulées ;
+- ajoute `redstoner:trophy_panel`, panneau mural configurable par son propriétaire avec un item non consommé, pages publiques, rendu en monde et rafraîchissement serveur limité à une fois par seconde ;
+- passe Sanctuary aux données v15 et Red-Stoner aux données v4 sans nouveau payload ni changement de leurs protocoles réseau 24 et 7.
+- corrige la cape blanche décorée en projetant sa couleur et ses motifs avec les sprites de bouclier, aux proportions exactes de la cape ;
+- permet d’équiper une poule adulte avec l’armure de loup vanilla en écailles de tatou, de la réparer avec des écailles et de la retirer aux cisailles ; l’armure absorbe les dégâts et conserve son usure, ses teintures et ses enchantements ;
+- conserve les sauvegardes Sanctuary v15 et le protocole réseau 24 : l’armure utilise exclusivement le slot d’équipement vanilla de la poule.
+
+## `26.2.0-alpha.229`
+
+Module modifié : **Red-Stoner `0.0.0-alpha.16`**.
+
+- ajoute au terminal les tris alphabétique, par quantité croissante et par quantité décroissante, appliqués explicitement sans déplacer les objets sous le curseur lors des rafraîchissements périodiques ;
+
+## `26.2.0-alpha.228`
+
+Modules modifiés : **Sanctuary `0.0.0-alpha.132`** et **Red-Stoner `0.0.0-alpha.15`**.
+
+- étend `sanctuary:backroom` à toute la hauteur Y -64 → 383 et empile cinq niveaux thématiques de haut en bas : seuil modulaire, archives, ville, services et glitch ;
+- remplace les volumes ouverts par des pièces et couloirs raccordés, quatre angles de salle déclinés en cinq matériaux, des bibliothèques immenses, des tours plus serrées, des autoroutes continues et de rares parcs ;
+- ajoute au niveau inférieur une grille de prismes 3D et un labyrinthe déterministe connecté, avec portes physiquement ouvertes, salles fusionnées et trous volontaires vers le vide ;
+- fait correspondre exactement chaque ouverture entre le sol supérieur et le plafond inférieur, place une torche récupérable à chaque arrivée et raréfie fortement les lits de sortie ;
+- supprime le ciel, les astres, la lumière ambiante et tous les monstres, y compris ceux injectés par un autre système ;
+- conserve les IDs, les données Sanctuary v14 et le protocole réseau 24 ; seuls les nouveaux chunks Backroom utilisent la nouvelle architecture complète ;
+- rend le champ de recherche du terminal inactif à l’ouverture puis focalisable au clic, libère le focus au clic extérieur et laisse toujours la touche d’inventaire fermer le terminal ;
+- permet à la recherche du terminal de retrouver une boîte de Shulker par le nom ou l’identifiant d’un objet qu’elle contient, tout en conservant la boîte comme résultat afin que son aperçu vanilla reste directement consultable ;

-Version courante du pack distribué : **`26.2.0-alpha.226`**. Cette release distribue Sanctuary **`0.0.0-alpha.130`** ; les neuf autres modules conservent leur version issue de l'alpha.225.
+Version courante du pack distribué : **`26.2.0-alpha.230`**. Cette release distribue Sanctuary **`0.0.0-alpha.136`** et Red-Stoner **`0.0.0-alpha.17`** ; les huit autres modules conservent leur version issue de l'alpha.229.
+
+Le prochain Red-Stoner **`0.0.0-alpha.18`** présente le panneau de trophées comme une plaque verticale de chêne et rend enfin ses quatre lignes lisibles : titre et numéro de page, puis les trois places du podium. Un clic droit avance d’une page et `Maj` + clic droit revient à la précédente ; les données v4 et le protocole réseau 7 restent inchangés.
+
+L’alpha.230 attribue les quêtes communautaires terminées à leur preneur et répartit les lits de sortie rares sur chacun des cinq niveaux de la Backroom. Elle ajoute aussi les classements publics et le panneau mural `redstoner:trophy_panel`, corrige la projection des couleurs et motifs de la cape blanche avec les sprites de bouclier, et permet d’équiper une poule adulte avec l’armure de loup vanilla en écailles de tatou. Les sauvegardes restent compatibles ; Sanctuary passe aux données v15 et Red-Stoner aux données v4 sans changer leurs protocoles réseau 24 et 7.
+
+L’alpha.229 ajoute au terminal les tris alphabétique, par quantité croissante et par quantité décroissante. Le tri ne change que sur demande explicite et les rafraîchissements périodiques conservent l’ordre ainsi que les objets sous le curseur. Les sauvegardes, les données Red-Stoner v3 et le protocole réseau 7 restent compatibles.
+
+L’alpha.228 reconstruit la Backroom sur cinq niveaux empilés entre Y -64 et Y 383. Le monde devient entièrement noir et sans monstres ; l’arrivée est signalée par une torche récupérable. Les nouveaux chunks composent seuils modulaires, bibliothèques et bureaux, ville dense avec autoroutes et parcs, couloirs techniques, puis une grille 3D et un labyrinthe connecté dont certains trous mènent au vide. Red-Stoner corrige aussi le focus du terminal et permet de retrouver une boîte de Shulker par son contenu. Les chunks déjà générés et les sauvegardes existantes restent compatibles.
+
+L’alpha.227 ajoute la dimension persistante `sanctuary:backroom`. On y entre accroupi devant un lit et on n’en ressort que par un lit. L’équipement d’entrée est transféré atomiquement vers la Mailbox, tandis que les objets perdus ou abandonnés dans la dimension alimentent des coffres renouvelables sans duplication. Les anciennes sauvegardes sont migrées vers Sanctuary data v14 sans réinitialisation ; le protocole réseau reste en version 24.
 
 L’alpha.225 corrige quatre tickets : posséder un coffre-fort devient obligatoire pour en braquer un autre, les familiers temporaires ne donnent plus de butin, d’expérience, de lootbox ni de progression de quête, les seize variantes Canaplia survivent à tout leur cycle de culture, et le Magic Carpet retrouve la texture historique du Totem de Notch à la place de la laine violette. Les IDs, sauvegardes, formats de données et protocoles restent compatibles.

 L’alpha.219 porte l'île finie Minecraft Indev dans `sanctuary:alpha` : 128 × 128 × 64 blocs déterministes, plages, cavernes, minerais, fluides, végétation et maison historique, le tout borné sans chunks parasites. Le cadre 4 × 5 en cobblestone moussue est maintenant actif et crée une paire persistante à une arrivée sûre hors de la maison. Ambiance peut enfin composer localement Golden Days Base puis Alpha uniquement dans cette dimension, sans redistribuer leurs textures et en restaurant exactement la pile précédente. Voir le [contrat Alpha](sanctuary/ALPHA.md), le [contrat des portails](iliketomoveit/PORTALS.md) et le [guide Golden Days](ambiance/GOLDEN_DAYS.md).
 
-L’alpha.218 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.

Un bouton permet enfin de trier explicitement les résultats par nom, quantité croissante ou quantité décroissante.
 
 L’alpha.217 tentait de compenser la hauteur trop grave du disque blanc par un facteur OpenAL de `4/3`. Cette compensation est retirée par l’alpha.221, qui corrige directement la conversion stéréo vers mono.

+
+Le panneau mural `redstoner:trophy_panel` consomme l’API publique de classement de Sanctuary sans conserver les scores. Le joueur qui le pose peut ajouter des pages statistiques en cliquant avec un item, tandis que tous les visiteurs peuvent faire défiler les pages. Sanctuary importe une fois les statistiques vanilla existantes, garde les classements par UUID — champion déconnecté compris — et fournit seulement un podium borné à trois entrées. Les composants privés de l’item servant d’icône et la base complète des joueurs ne sont jamais synchronisés au client.
 
 L'ordinateur 8 bits et le contrôleur exécutent la machine virtuelle historique : programme assembleur borné à 4 096 caractères, RAM, inventaire, six ports redstone directionnels, impulsions et sortie comparateur. Le contrôleur dispose de 1 024 cellules de RAM contre 256 pour l'ordinateur. L'instruction destinée à la matrice d'affichage renvoie volontairement une erreur claire tant que ce périphérique reste différé.

-Les plans sont déterministes par grandes zones et utilisent cinq familles composées :
+La liste [Normal Levels I](https://backrooms-wiki.wikidot.com/normal-levels-i) sert uniquement de
+référence d’ambiance et de vocabulaire. Les plans, palettes et règles ci-dessous sont originaux au
+pack ; aucun texte ni visuel du wiki n’est embarqué.
 
-- mégalopoles en béton, verre, pierre et voirie ;
-- bureaux superposés en bois, clay, textile et éléments techniques ;
-- plaines naturelles avec arbres et rares ruines ;
-- agrégats de plateformes et de pièces flottantes reliées verticalement ;
-- pièces construites visuellement à 90° ou à l’envers, sans modifier la gravité globale.
+La dimension couvre maintenant toute la hauteur de **Y = -64 à Y = 383**. Ses cinq niveaux sont
+numérotés de haut en bas afin qu’une chute fasse toujours avancer vers le niveau suivant :
 
-Les matériaux très marqués d’Another World n’apparaissent que ponctuellement aux anomalies. Aucun

+- **niveau 0 — Seuil, Y 295 à 383** : cinq plans de pièces jaunes et sableuses, avec couloirs,
+  cloisons à 90°, colonnes et quatre angles de salle. Chaque angle possède cinq variantes de
+  matériaux ; des trous rares relient les plans superposés ;
+- **niveau 1 — Archives, Y 206 à 294** : quatre étages de bureaux et de bibliothèques pouvant
+  couvrir plusieurs chunks, avec longues rangées de rayonnages, grandes fenêtres intérieures,
+  salles de lecture et cloisons ouvertes ;
+- **niveau 2 — Ville, Y 117 à 205** : bâtiments rapprochés séparés par de petites ruelles,
+  autoroutes orthogonales continues, tours à plusieurs étages et rares parcs enfermés sous le
+  plafond de la dimension ;
+- **niveau 3 — Services, Y 28 à 116** : cinq plans de couloirs techniques en briques, grilles et
+  béton, dont toutes les jonctions de portes restent physiquement ouvertes ;
+- **niveau 4 — Glitch, Y -64 à 27** : prismes de briques en grille 3D autour d’un toit où l’on peut
+  tomber, puis réseau déterministe de salles et couloirs. Chaque cellule du labyrinthe conserve une
+  route ouverte vers son origine ; certaines cloisons disparaissent pour fusionner des salles de
+  tailles différentes. De rares trous dans le dernier plancher mènent au vrai vide.
+
+Les ouvertures entre deux niveaux sont calculées une seule fois puis appliquées à la fois au sol
+supérieur et au plafond inférieur : une chute annoncée ne débouche donc pas sur un bloc fermé. Les
+imperfections, morceaux suspendus et raccords volontairement cassés font partie de l’esthétique,
+mais les portes des couloirs restent traversables. Chacun des cinq niveaux génère exactement un lit
+de sortie par cellule de 3 × 3 chunks, sur un plancher praticable propre à sa zone. Il n’est donc
+plus nécessaire de parcourir une centaine de chunks ou de remonter jusqu’aux Archives pour ressortir.
+
+La Backroom ne possède ni ciel, ni soleil, ni lune, ni étoiles, ni lumière ambiante. Son biome ne
+déclare aucune créature et le serveur retire aussi toute entité de catégorie monstre qui y serait
+injectée par un autre système. Les matériaux très marqués d’Another World n’apparaissent que
+ponctuellement aux anomalies. Aucun bloc précieux ne sert de matériau structurel ; de très rares
+blocs de diamant restent cachés dans les fondations.
