+# GEM-01 — Gemmes, argile et découvertes — beta.126
+
+Contrat du 17 septembre 2026, branche `codex/gems-beta126`, Minecraft 26.3.
+
+Deux gemmes natives complètent l'émeraude : `sanctuary:ruby` et
+`sanctuary:sapphire`. Chaque famille comprend un bloc de stockage, un minerai
+ordinaire et un minerai des abîmes. Les huit PNG du créateur sont copiés à
+l'identique ; leurs empreintes figurent dans `tools/gems-textures-beta126.json`.
+Les noms des fichiers français `saphir` sont associés aux identifiants anglais
+stables `sapphire`, sans modifier les pixels. Les deux items utilisent les fichiers de remplacement
+`Desktop/ruby.png` et `Desktop/saphir.png` fournis en fin de livraison.
+
+L'ordre créatif est émeraude, rubis, saphir : ingrédients, blocs de stockage,
+minerais ordinaires et minerais des abîmes dans leurs onglets natifs respectifs.
+Minage à la pioche de fer ou mieux, résistance et expérience comme l'émeraude,
+Fortune, Toucher de soie, cuisson/four à fusion et conversion 9 gemmes ↔ 1 bloc.
+Les blocs peuvent former un socle de balise et les gemmes servir de paiement.
+Les recettes rejoignent la collection actuelle de l'émeraude, sans ajouter de
+transactions de villageois. Libellés français et anglais, tags communs `c:`.
+
+## Génération procédurale et contrat de compatibilité
+
+Profil initial **gemmes 1 / beta.126** : quatre tentatives par chunk et par
+gemme, filons natifs de taille 3, hauteur uniforme Y0–256, probabilité de rejet
+au contact de l'air de 0,25. Ces nombres sont un réglage initial à équilibrer
+lors de la future refonte ; aucun quota de gemmes par chunk n'est garanti.
+Les variantes ordinaires remplacent les roches du tag vanilla
+`stone_ore_replaceables`, les variantes des abîmes celles de
+`deepslate_ore_replaceables`.
+
+Les fichiers `worldgen/feature/ore_<gemme>.json`,
+`worldgen/placed_feature/ore_<gemme>.json` et les tags de biomes
+`has_ore/<gemme>` séparent les cibles, la forme, la fréquence, la hauteur et
+les régions. Un datapack peut les remplacer sans recompiler le mod. Le code
+réutilise `OreFeature` et le hasard natif issu de la graine ; il limite ces
+filons aux mondes utilisant `SanctuaryChunkGenerator`. Les biomes vanilla
+partagés avec Sanctuary restent compatibles sans ajouter les gemmes aux
+mondes vanilla, au Nether ou à l'End.
+
+Cette évolution additive est autorisée pour les **nouveaux chunks uniquement**.
+Aucun remplissage rétrospectif, aucune régénération, aucun remplacement de chunk
+sauvegardé ni activation d'expansion. Les codecs du relief, les dimensions et
+le format des sauvegardes restent inchangés. Les filons suivent les protections
+existantes de la décoration native. Les anciens profils expérimentaux précédant
+le générateur Sanctuary unifié ne sont pas étendus.
+
+## Argile spéciale dans le Clay Workshop
+
+Le bloc d'argile vanilla conserve les couleurs échantillonnées sur le modèle
+original, animal découvert ou import GLB. Les argiles colorées et les autres
+blocs continuent à transférer leur palette de texture. Une même règle est
+appliquée à l'aperçu client et au résultat serveur. Le changement de matériau
+invalide le résultat même si les deux palettes sont identiques. Le texte de
+l'atelier explique l'exception en français et en anglais.
+
+Une sculpture coûte toujours un bloc ; aucune recette, découverte, donnée de
+sculpture déjà fabriquée ni règle de placement n'est modifiée.
+
+## Commande de découverte commune
+
+`/sanctuary discovery all` découvre tous les blocs, objets et espèces enregistrés.
+Les variantes `blocks all`, `items all` et `mobs all` ciblent une catégorie ;
+`block <identifiant>`, `item <identifiant>` et `mob <identifiant>` ciblent une
+entrée avec la complétion native. Un sélecteur de joueurs en fin de commande
+est facultatif ; sans cible, elle s'applique au joueur qui l'exécute.
+
+Exemples :
+
+```mcfunction
+/sanctuary discovery all
+/sanctuary discovery mobs all
+/sanctuary discovery block minecraft:stone
+/sanctuary discovery item minecraft:diamond
+/sanctuary discovery mob minecraft:cow
+/sanctuary discovery all @a
+```
+
+La permission suit « Autoriser les commandes » en solo et les droits opérateur
+sur serveur. La console doit préciser la cible. Les identifiants invalides,
+l'air et les types d'entités sans espèce découvrable sont refusés.
+
+Les blocs passent par le registre de découvertes et son événement existant ;
+les objets passent par `RecipeService.discover`. Les collections et recettes
+sont ensuite recalculées normalement. Les espèces rejoignent `seen_mobs`,
+la même donnée que l'observation naturelle, consommée par les familiers,
+le Métabli et le Clay Workshop. Il n'existe aucun drapeau de déblocage parallèle.
+Les catalogues déjà ouverts sont à rouvrir après la commande.
+
+La commande conserve les quantités possédées et les compteurs de combat,
+minage, pose et fabrication. Elle ne donne pas d'objets, n'achète pas les skills
+et n'attribue pas d'advancements. Les recettes réservées aux opérateurs gardent
+leurs règles. Les historiques personnels sont enrichis sans changer leur
+schéma ; la commande refuse les données illisibles plutôt que les remplacer.
+
+## Vérifications
+
+Client natif Minecraft 26.3 / Java 25, `Gems126ClientChecks`, réussi en
+1 min 08 s. Les mondes sont jetables, sans sauvegarde personnelle ouverte :
+
+- Les huit items et six blocs sont présents, avec les huit textures exactes.
+  Quatre groupes créatifs respectent émeraude → rubis → saphir, sans doublons.
+- Douze recettes natives, découverte du bloc de stockage, outil fer minimum,
+  Fortune III, Toucher de soie et balises passent les contrôles serveur.
+- Graine **126**, profil gemmes 1, 81 chunks autour de l'origine : 7 rubis dans
+  la pierre et 8 dans la roche des abîmes ; 15 saphirs dans la pierre et 10 dans
+  la roche des abîmes. La génération est refusée dans le monde plat vanilla.
+  Les minerais persistent à la reconnexion, et un minerai retiré ne réapparaît pas.
+- L'argile conserve exactement les couleurs des voxels d'une vache et d'un GLB
+  texturé. Bois et argile colorée transfèrent toujours leur palette. Le retour
+  à l'argile, l'égalité aperçu/résultat et le coût d'un bloc en survie sont vérifiés.
+- La commande native respecte « Autoriser les commandes », accepte une cible
+  et la console, refuse les identifiants invalides et permet une espèce, un
+  bloc, un objet, toutes les espèces ou tout le contenu. Les recettes liées
+  sont recalculées. La répétition est idempotente et les découvertes survivent
+  à la reconnexion sans inventer de compteurs de combat ou de possession.
+
+Logs et captures dans `build/gems126-client.log` et
+`mods/sanctuary/build/run/clientGameTest/screenshots/`. Le GameTest dédié
+reste exclu conformément au refus antérieur de son EULA. Le build complet et

+d'items ; les huit fichiers livrés sont vérifiés à l'octet près contre les
+sources, tous en 16 × 16. Les JAR de sources correspondent aux sources courantes.
+L'audit entre les binaires beta.125 et beta.126 ne trouve que les 112 entrées
+de production prévues. Les archives normal/Test contiennent le même mod et
+le template reproduit exactement ses ressources exportables.

+# TOOL-01 — Clé dorée et états de blocs — beta.120
+
+Contrat du 17 septembre 2026, branche `codex/golden-wrench-beta120`.
+Le créateur valide les gestes du debug stick : clic gauche choisit la propriété,
+clic droit parcourt ses valeurs, Maj inverse le parcours. L'orientation est
+proposée en premier, puis les propriétés de forme et les autres états natifs.
+La sélection est personnelle, par type de bloc, pour la session courante.
+Une indication dans la barre d'action affiche la propriété et sa valeur.
+La clé ne casse pas le bloc, y compris en créatif, et ne remplace pas son type.
+
+Les propriétés natives sont disponibles en survie avec la clé, sans condition
+opérateur, dans le respect des droits de construction, protections, portée et
+verrous de conteneurs. Comme avec le debug stick, les formes choisies restent
+en place immédiatement ; les mises à jour ultérieures du jeu peuvent recalculer
+les états dynamiques (redstone, connexions, cultures…).
+
+Les multiblocs assemblés gardent leurs commandes d'ouverture/dissociation et
+leurs propriétés techniques ne sont pas éditées individuellement. Un assemblage
+complet garde priorité au clic droit ; Maj permet de régler les composants
+non assemblés. Hors d'un assemblage complet, même un four, un baril, un piston
+ou un établi reçoit l'action générique.
+
+## Rotation de texture et contrat de stockage
+
+La terre n'a pas d'orientation dans son blockstate vanilla. Une propriété
+supplémentaire de la clé, « Rotation des textures », parcourt 0°, 90°, 180° et
+270° sur les faces des modèles de blocs. La géométrie, l'éclairage, les teintes,
+les ressources actives, le bloc, son inventaire et son butin restent natifs.
+Les rendus spéciaux d'entités de blocs ne sont pas transformés par ce réglage
+des faces ; leur orientation demeure modifiable par leurs états natifs.
+
+Nouvelle donnée facultative `sanctuary:wrench_textures_v1`, attachée au chunk :
+table immuable position entière → quart de tour (1 à 3). Une absence signifie
+0°. Elle n'est créée qu'après une action de clé ; revenir à 0° retire l'entrée,
+puis l'attachement s'il est vide. Aucun état vanilla ni format existant n'est
+modifié ; aucun parcours, conversion ou régénération des anciens mondes.
+Les modifications de blockstate du même type conservent la rotation. Casser,
+remplacer ou déplacer par piston retire la rotation à l'ancienne position ;
+les objets récupérés restent ordinaires. Les nouveaux clients la reçoivent
+après le chunk natif, par lots bornés de 1 024 entrées au maximum.
+Déconnexion, changement de dimension et déchargement libèrent le cache visuel.
+Revenir à une ancienne version du mod supprime seulement cet effet visuel ;
+les blocs conservent leurs identifiants, données et états natifs.
+
+## Vérifications et livraison
+
+Le parcours `Wrench120ClientChecks` passe en **47 s** sur Minecraft 26.3,
+client macOS et serveur intégré, dans un monde plat jetable de graine 120 :
+
+- **2 522 propriétés natives** parcourues, avec valeurs inverses et type conservé.
+- Vrais clics sur les escaliers : orientation, moitié supérieure et forme,
+  sans casser le bloc en créatif ; gestes inverses et sélection distincte.
+  Les doubles événements créatifs d'un même clic sont filtrés à la cadence
+  native de cinq ticks.
+- Terre en survie : rotation réelle des UV émis, positions des sommets et nombre
+  de faces identiques ; retour exact après quatre quarts de tour ou un inverse.
+- Rechargement des ressources conservant les UV tournés ; capture de terre relue.
+- Coffre tourné avec ses 23 diamants intacts, sans ouverture accidentelle.
+- Assemblage/dissociation par vrais clics des quatre familles : Métabli, Fût,
+  Fourneau et super piston. Un clic gauche sur un assemblage ne modifie pas
+  les numéros de composants ; barils et pistons isolés tournent normalement.
+- Refus en aventure, spectateur ou hors portée ; retrait des données visuelles
+  après remplacement, maintien lors d'un changement d'état du même bloc.
+- Sauvegarde/reconnexion : rotation de terre côté serveur et client, état
+  natif de l'escalier et inventaire du coffre conservés.

+# Préparation locale des ombres portées pixélisées (ancien numéro beta.122)
+
+Ticket du 17 septembre 2026, branche locale `codex/pixel-shadows-beta122`.
+Cette préparation n'a jamais été publiée sous le numéro beta.122, déjà utilisé
+par une autre livraison. Elle est intégrée au socle beta.126 et livrée en
+[beta.127](shader-beta127.md). Les chemins et mesures ci-dessous décrivent
+les essais historiques dans le dossier de préparation.
+Demande : ajouter aux réglages de Sanctuary · Vanilla Light des ombres portées
+pixélisées, avec une finesse et une distance réglables.
+
+## Utilisation
+
+Dans **Options → Shaders**, activer **Sanctuary · Vanilla Light**, puis
+**Ombres portées pixélisées**. L'option est désactivée par défaut pour conserver
+le coût et le rendu des installations existantes. Les choix sont :
+
+- finesse de **8, 16 ou 32 pixels par bloc**, défaut 16 ;
+- distance de **16, 32 ou 64 blocs**, défaut 32.
+
+Ces préférences sont conservées dans `config/sanctuary-shaders.json`, avec les
+anciens champs de couleur. Leurs valeurs numériques sont ramenées aux choix
+admis au chargement. Les libellés et explications sont disponibles en FR/EN.
+Les réglages s'appliquent sans recharger les ressources.
+
+## Rendu et périmètre
+
+Une carte de profondeur rend les formes d'occultation des blocs solides chargés
+autour de la caméra, indépendamment de leur présence à l'écran. Les dalles et
+escaliers conservent leurs formes. Le cache est invalidé par les changements de
+blocs, les paquets de chunks et les reconstructions du moteur natif.
+La direction solaire vient du ciel natif extrait par Minecraft, et respecte
+ainsi l'angle solaire de Sanctuary. L'effet s'atténue sous la pluie, à l'horizon,
+dans la brume et à la limite de sa portée. Il s'arrête la nuit, dans les dimensions
+sans soleil, dans les fluides et lorsqu'un moteur externe suspend Vanilla Light.
+
+La profondeur du monde est lue directement par le GPU après le rendu du monde,
+avant la main et l'interface. L'inverse de la projection réelle inclut les effets
+de caméra. Les points recevant l'ombre sont arrondis sur une grille ancrée dans
+le monde ; le plan de la face est conservé pour limiter les auto-ombres.
+La carte solaire utilise également une origine alignée sur ses texels.
+Le HUD, la main, les étoiles et les captures panoramiques techniques gardent leur
+chemin de rendu. Aucun niveau de lumière de gameplay, règle serveur, sauvegarde
+ou générateur n'est changé. Aucune dépendance de rendu n'est ajoutée.
+
+Cette première version couvre les **formes d'occultation des blocs** : les entités
+conservent leurs ombres natives ; les feuillages ajourés, modèles non occultants,
+block entities animés, eau et verre ne projettent pas de nouvelles silhouettes.
+Les transparences et particules déjà composées peuvent recevoir l'assombrissement
+du terrain derrière elles. Il n'y a pas d'ombres de lune ou de torches, ni de
+séparation de l'éclairage local émissif dans cette passe d'assombrissement.
+
+## Coût et cycle de vie
+
+Les maillages sont mis en cache par section de 16³, avec au plus quatre sections
+commencées par image et un budget souple de 3 ms pour leur construction. Les
+ombres apparaissent progressivement pendant la préparation après activation ou
+déplacement. Le volume des obstacles part de la portée choisie avec une marge de huit blocs,
+puis s’étend vers le soleil sur deux fois cette portée, arrondi aux sections.
+Les obstacles au-delà de ce volume ou dans des chunks non chargés ne sont pas
+représentés. Les mises à jour de lumière seule ne reconstruisent pas les formes.
+Le cache de sommets est plafonné à 96 Mio et omet les formes pathologiques qui
+dépassent ses limites. Les textures de profondeur font entre 512 et 4 096 pixels
+de côté selon finesse et portée. Le coût exact dépend de la scène et du GPU.
+
+Les ressources sont libérées à la désactivation, au changement de monde, à la
+reconstruction des ressources et à l'arrêt du client. Cette livraison est locale :
+aucun avancement du canal packwiz ni installation personnelle ne fait partie du
+ticket.
+
+## Vérification
+
+Validation native sur **Minecraft 26.3, Java 25, macOS / Apple M1, OpenGL 4.1**,
+dans un nouveau monde plat de développement, graine **122** :
+
+- Comparaison GPU activation/désactivation sur une plateforme blanche avec
+  pilier, dalle et escalier : **920 échantillons assombris**, 63 412 inchangés,
+  aucun éclairci sur les 64 332 échantillons de sol retenus.
+- Pilier entièrement hors du frustum : **42 048 échantillons** restent dans
+  son ombre. Le retrait du pilier restitue la lumière sur **42 048 / 42 048**
+  échantillons et préserve les 23 616 échantillons déjà éclairés. Sa repose
+  restitue la même ombre, sans désactiver le cache entre ces manipulations.
+- Les trois finesses et les trois portées sont appliquées en direct ; les cartes
+  GPU sont redimensionnées aux dimensions attendues. Désactiver l'option libère
+  la texture et ne soumet plus de passe d'ombres.
+- À minuit, activer ou désactiver l'option donne la même image et aucune passe
+  solaire n'est soumise. Au retour du jour, le rendu reprend.
+- Le rechargement des ressources restitue la même image. Les préférences
+  persistent à la relecture du fichier et leurs valeurs extrêmes sont bornées.
+- Menus FR/EN inspectés en capture ; les libellés tiennent dans les contrôles
+  natifs à la taille de test. Les vues de finesse 8/16/32 sont conservées.
+
+```sh
+./gradlew :sanctuary:runClientGameTest \
+  -PsanctuaryClientTests=true -PsanctuaryPixelShadows122ClientTests=true \

+`build/pixel-shadows122-client.log`. Captures inspectées dans
+`build/pixel-shadows122-evidence/final/`. Les pixels sont relus uniquement dans
+le test ; le code de rendu de production n'effectue aucune lecture CPU de GPU.
+Les premiers démarrages ont permis de corriger les identifiants de pipelines,
+la directive GLSL `#include` attendue par 26.3 et deux libellés répétés du menu.
+
+La commande de livraison est :
+
+```sh
+./gradlew check build assemblePack assembleTestPack -x :sanctuary:runGameTest
+```
+
+Le serveur GameTest dédié est exclu, conformément au refus de son EULA déjà
+consigné dans les livraisons précédentes. Le test graphique utilise le serveur
+intégré de son monde neuf. Aucun monde personnel n'est ouvert.
+La construction finale **réussit en 2 min 18 s** (126 tâches), journal
+`build/pixel-shadows122-build-final.log`. Le contrôle des archives confirme
+**868 sources Java** et **1 869 classes** identiques aux sorties construites,
+les ressources GLSL/FR/EN exactes dans le JAR et le template, et le même JAR
+dans les profils packwiz normal et Test. Aucune fixture cliente n'est embarquée.

+
+Pas de mesure de FPS, d'essai Windows/Vulkan, de pack Iris ni de silhouettes
+animées revendiqués. Le shader reste un assombrissement graphique appliqué au
+rendu opaque et déjà composé, avec les limites de transparence décrites plus haut.

+# RP-02 — Clé dorée et pack personnel — beta.121
+
+Contrat du 17 septembre 2026, branche `codex/resourcepack-template-beta121`.
+Le créateur fournit `golden_wrench.png` et valide un bouton qui crée une copie
+personnelle complète, modifiable et jamais écrasée par les mises à jour.
+
+## Résultat
+
+La clé dorée reprend exactement le PNG fourni, 16 × 16, sans conversion ni
+redessin. Le modèle reste un item plat `minecraft:item/handheld`. Empreinte :
+`a97570908db75caf8e6fc2f5ecabf12c54fd99bfea7be634df66c4310dca22af`.
+Le même fichier est fourni par le mod et par « Textures Sanctuary » ; désactiver
+le pack intégré conserve donc aussi la nouvelle clé.
+
+Dans **Options → Packs de ressources**, **Personnaliser Sanctuary** crée
+`resourcepacks/Sanctuary-Custom/`. Le bouton devient **Ouvrir ma copie**.
+La copie contient toutes les ressources client de Sanctuary : textures, modèles,
+étiquettes d'items, blockstates, sons, shaders, langues et remplacements Minecraft
+présents dans le pack intégré. Celui-ci prend priorité sur les assets de base
+lors de l'export. Un guide FR/EN, la licence et les crédits accompagnent la copie.
+
+Le joueur active sa copie avec les commandes natives et la place au-dessus des
+packs qu'il veut remplacer. Créer la copie ne change ni l'ordre ni la sélection.
+Une modification se recharge avec F3 + T ; désactiver le pack retrouve les
+ressources fournies par le mod. L'écran de sélection des datapacks n'est pas modifié.
+
+La copie est un **instantané**. Elle ne se synchronise pas avec les mises à jour :
+les fichiers personnalisés restent toujours intacts. Le guide recommande de
+supprimer les fichiers non personnalisés pour laisser les prochaines ressources
+du mod s'appliquer. Pour repartir d'un instantané récent, renommer le dossier
+existant puis créer une nouvelle copie. Aucun fichier utilisateur n'est écrasé.
+
+La copie s'effectue hors du fil de rendu, dans un dossier temporaire voisin,
+puis le résultat complet rejoint la liste native. Une erreur de copie est
+signalée par le bouton et le journal du jeu ; un chemin occupé par un fichier
+n'est pas remplacé. Aucune extraction au démarrage ni pendant les mises à jour.
+
+## Distribution
+
+`./gradlew assembleResourceTemplate` produit
+`build/Sanctuary-Template-beta.121.zip`, un pack personnel complet à décompresser
+dans `resourcepacks/Sanctuary-Custom/`. `assemblePack` le produit aussi.
+`build/Sanctuary-Resource-Pack-beta.121.zip` reste l'export du pack graphique
+intégré ; son manifeste versionné contient 151 fichiers et les images historiques
+sont conservées. L'identifiant intégré `sanctuary:textures` reste stable et son
+activation reste contrôlée par le joueur.
+
+Le template ne contient pas tous les assets vanilla ni ceux des autres mods.
+Il ne contient pas les recettes, règles serveur ou sauvegardes. Il conserve
+les crédits et conditions des ressources d'origine. Aucune génération, aucun
+identifiant de bloc et aucun format de sauvegarde ne changent.
+
+## Vérifications
+
+Le parcours `ResourceTemplate121ClientChecks` passe en **35 s** sur le client
+Minecraft 26.3 macOS, sans ouvrir de monde :
+
+- Bouton natif et disposition FR/EN aux échelles 2 et 3, captures relues.
+- Export complet de **1 202 fichiers**, empreintes identiques aux ressources
+  sources après application des priorités du pack intégré.
+- PNG fourni vérifié par SHA-256 et affiché avec sa transparence.
+- Création sans changer la sélection ni l'ordre des packs.
+- Modification d'une texture et ajout d'un fichier personnel : aucun octet
+  réécrit lors d'un second export ni au rechargement des ressources.
+- Priorité réelle de la texture personnalisée, puis retour à la clé fournie
+  après désactivation. Activation et désactivation conservées à la redécouverte.
+- Chemin occupé par un fichier refusé sans le modifier ; aucun bouton ajouté
+  à l'écran des datapacks.

+# SCULPT-10 — Une boîte par sculpture — beta.124
+
+Contrat du 17 septembre 2026, branche `codex/sculpture-bounds-beta124`.
+Le créateur choisit **une seule boîte pour la sélection et les collisions**.
+Ce ticket remplace la forme physique détaillée de beta.122.
+
+La boîte englobe exactement les dimensions occupées par la sculpture, après
+orientation et ancrage au centre ou au bord. Elle suit toujours la grille 1/16,
+y compris les tailles impaires et les modèles comportant des marges vides.
+Les trous et petits détails restent visibles mais n'ont plus leurs propres
+surfaces de collision : on ne grimpe plus sur leurs petites marches. Une arche
+se sélectionne et bloque désormais sur tout son volume englobant.
+
+La pose utilise la même boîte avant la création de l'entité de bloc : elle
+refuse une intersection avec le joueur, y compris dans les trous visuels.
+Les petites sculptures laissent libre le reste du bloc autour de leur boîte.
+La forme reste mise en cache par modèle et état ; elle ne se recalcule qu'après
+un changement de modèle, d'orientation ou d'ancrage. Les requêtes physiques et
+le contour partagent cette même forme native.
+
+Le calcul parcourt les cellules une seule fois, sans créer de copies tournées
+ni de grille de collisions 16³. Le contour émet toujours douze arêtes.
+Il s'agit d'une simplification du travail géométrique ; aucun gain de FPS global
+n'est annoncé sans mesure sur une scène représentative.
+
+Le rendu des sculptures et les règles de lumière de beta.122 restent inchangés :
+pas d'occlusion de cube plein, pas d'émission artificielle de lumière. Aucun
+identifiant, format d'item ou de sauvegarde ne change. Les anciennes sculptures
+utilisent la nouvelle forme à partir de leurs données existantes, sans réécriture
+des mondes ni régénération de chunks. L'atelier et les clés restent inchangés.
+

+**39 s** sur Minecraft 26.3, client macOS et serveur intégré jetable de graine 122.

+  orientations et cinq ancrages.

+# STAT-07 — Pose centrée des sculptures — beta.119
+
+Contrat du 17 septembre 2026, branche `codex/sculpture-center-beta119`.
+
+Viser le carré central de 8 × 8 pixels de la face supérieure ou inférieure
+du bloc place la sculpture au centre. Les limites de cette zone sont incluses.
+Autour, le bord horizontal le plus proche reste choisi ; une pose latérale
+continue à s'appuyer contre le bloc support. L'orientation suit le regard.
+L'aide du Clay Workshop explique les deux possibilités en français et anglais.
+
+Le centrage utilise l'emprise réelle des voxels après rotation, en ignorant les
+marges transparentes. Tous les sommets restent sur la grille de 1/16 de bloc.
+Une dimension impaire ne peut pas être parfaitement symétrique dans un bloc de
+16 pixels sans décaler ses voxels : elle prend donc le centrage entier le plus
+proche, avec un pixel de différence entre les deux marges. Aucune position à
+un demi-voxel n'est introduite.
+
+## Compatibilité
+
+La pose réutilise `anchor=center`, déjà présent depuis beta.113. Aucun nouvel
+état, identifiant, composant ou format de sauvegarde. Les sculptures existantes
+gardent leur ancrage ; casser et reposer choisit l'emplacement visé. Le rendu,
+les couleurs, les chapeaux et les collisions restent inchangés. Aucun parcours
+de monde existant, aucune régénération. Client et serveur doivent utiliser
+ensemble la nouvelle version pour le choix de pose.
+
+## Vérifications et livraison
+
+Le parcours natif `Statuary106ClientChecks`, avec `Sculpture113ClientChecks`,
+passe en **54 s** sur Minecraft 26.3/macOS :

+- Vrais clics de pose centrée dans quatre orientations, sur client et serveur,

+# SCULPT-11 — Placement, éclats et modèles découverts — beta.125
+
+Contrat du 17 septembre 2026, branche `codex/sculpture-placement-beta125`.
+
+Le point visé choisit neuf positions horizontales (centre, quatre bords et quatre
+coins) et trois hauteurs (bas, milieu et haut). Sur un support, la sculpture
+repose au bas de son bloc ; sous un plafond, elle touche le haut ; sur une face
+latérale, elle suit la hauteur visée et reste contre le support. Les sculptures
+restent debout et s'orientent selon le regard horizontal du joueur.
+La bande centrale occupe les huit pixels médians, limites incluses. Toute pose
+reste sur la grille 1/16 : une dimension impaire utilise le centre entier le
+plus proche, jamais un demi-voxel. Rendu, boîte unique de sélection et collision
+partagent les mêmes offsets. La lumière conserve les règles de beta.122.
+
+## Compatibilité additive des états existants
+
+Les cinq anciennes valeurs `anchor` gardent exactement leurs noms. Quatre
+valeurs de coin sont ajoutées. La nouvelle propriété `vertical_anchor` accepte
+`bottom`, `center`, `top` et `original`, valeur par défaut réservée à la
+compatibilité. La lecture d'un ancien bloc sans cette propriété conserve
+l'ancienne hauteur, même si le modèle a des marges transparentes en bas.
+Le bloc possède 144 états : 108 placements nouveaux et 36 états de compatibilité.
+
+Le schéma 1 des sculptures, leurs données de voxels et tous leurs identifiants
+restent inchangés. Aucun monde n'est parcouru ou réécrit, aucun chunk régénéré.
+Les nouveaux ancrages nécessitent beta.125 ; le retour à une version antérieure
+ne garantit pas leur position. Ce contrat autorise l'ajout compatible des états,
+pas une migration destructive des sauvegardes personnelles.
+
+## Particules
+
+Les coups et la casse émettent des éclats de la couleur des surfaces voxelisées
+réellement affichées, avec leur orientation et leur ancrage. Un coup vise la
+surface réelle la plus proche du point sélectionné, même devant un trou visuel.
+La casse échantillonne au plus 64 faces ; aucun calcul de texture n'est refait.
+Les éclats utilisent une taille de voxel, la gravité et la lumière natives.
+Une petite mémoire par monde (128 entrées de 64 faces, validité 40 ticks) conserve les
+surfaces si la suppression du bloc précède l'événement de casse. Les autres
+blocs gardent leurs particules habituelles.
+
+## Clay Workshop
+
+L'onglet Animaux utilise exactement les découvertes serveur du catalogue de
+statues (rencontre, victoire ou mort face à l'espèce). Le menu transmet cette
+liste à chaque ouverture, sans dépendre d'une visite préalable au Métabli.
+Le modèle natif et sa texture sont capturés localement, voxelisés en miniature,
+puis recolorés par la matière choisie. Le résultat reste fabriqué et payé côté
+serveur. Les sélections d'espèces non découvertes sont refusées. L'onglet Imports
+conserve les fichiers GLB. Aucun nouveau format de sculpture n'est introduit.

+# SCULPT-09 — Forme physique et lumière — beta.122
+
+Contrat du 17 septembre 2026, branche `codex/sculpture-shape-light-beta122`.
+Le créateur demande des bounding boxes adaptées aux sculptures et la suppression
+des ombres cubiques visibles lorsqu'on en pose plusieurs côte à côte.
+
+La sélection, le contact avec les entités et les collisions suivent les voxels
+occupés de chaque sculpture, y compris les creux. Le rendu et la forme physique
+partagent leur placement entier sur la grille 1/16, après orientation et ancrage.
+Le centre, les quatre bords et les dimensions impaires gardent leur alignement.
+La pose vérifie aussi les voxels portés avant que l’entité de bloc existe :
+elle refuse une intersection avec le joueur et autorise les espaces libres.
+La forme est construite directement sur une grille native 16³ et mise en cache
+par entité de bloc, modèle et état ; aucun calcul complet à chaque interrogation.
+
+Les sculptures transmettent la lumière et ne sont plus utilisées comme cubes
+pleins par l'occlusion ambiante. Leurs faces restent éclairées par le monde,
+sans émission de lumière et sans rendu à luminosité maximale. Cette règle est
+commune aux sculptures : l'éclairage natif stocké par bloc ne permet pas une
+ombre distincte pour chaque petit voxel. L'atelier d'argile reste inchangé.
+
+Aucun identifiant, blockstate, format d'item ou schéma sauvegardé ne change.
+Les formes sont recalculées à partir des voxels existants ; aucune migration,
+aucun parcours de monde ni régénération de chunk. Les données inconnues gardent
+leur conservation opaque et une petite base sélectionnable pour récupérer l'item.
+Le travail de documentation déjà présent dans l'autre branche reste intact.
+
+## Vérifications et livraison

+Le parcours `Sculpture122ClientChecks` passe en **37 s** sur Minecraft 26.3,

+  à travers le trou d'une arche jusqu'au bloc derrière, captures relues.
+- Requêtes natives de collision côté serveur et client : voxels occupés solides,
+  espace vide libre, aucune profondeur artificielle d'un bloc entier.
+- Pose refusée dans le joueur, sans consommer l'objet ; petite sculpture acceptée
+  dans la partie libre du même bloc, sans intersection avec le joueur.
+- **80 cas** confrontent le volume et les faces de collision au maillage réellement
+  émis : arche creuse, marges vides, cube de 4 096 voxels, voxel unique, quatre
+  orientations et cinq ancrages. Chaque interrogation répétée réutilise la forme.
+- Régression de **5 120 placements** du rendu existant : dimensions paires/impaires,
+  orientations et ancrages, plus marqueurs de direction et modèles avec marges.
+- Changement d'orientation/ancrage puis changement des voxels sur la même entité :
+  cache recalculé et forme client synchronisée.
+- **75 sculptures en trois couches** : skylight natif conservé à 15 partout.
+  Un toit de pierre témoin produit toujours une ombre. La lumière d'un bloc
+  traverse une sculpture avec l'atténuation de distance native (13 à deux blocs).

+les règles serveur, les sauvegardes et la génération ne sont pas modifiées.
+
+La préparation limite le cache à 96 Mio et sa construction à quatre sections
+par image dans un budget souple de 3 ms. L'intégration supprime seulement une
+invalidation de bord exécutée deux fois à l'identique dans le cache de terrain.
+Les formes non occultantes, feuillages ajourés, eau/verre et entités animées ne
+projettent pas de nouvelles silhouettes. Les transparences déjà composées
+peuvent recevoir l'assombrissement du terrain situé derrière elles. Pas
+d'ombres de torches/lune ni de mesure de FPS revendiquée.

+# SHADER-128 — stabilité, lune et feuillage
+
+Demandes du 17 septembre 2026 : réduire le jitter des bords et à midi, conserver
+des ombres de blocs nettes et un feuillage nuancé, ajouter une ombre lunaire
+fine et une transmission
+irrégulière du feuillage selon son épaisseur. Branche `codex/moon-foliage-beta128`,
+socle publié beta.127, Minecraft 26.3 / Java 25.
+
+## Résultat
+
+Les faces de voxels reçoivent l'ombre sur une grille fixe ; leur plan est
+stabilisé au 1/16 de bloc et les faces inclinées conservent leur normale. La
+carte de profondeur utilise un ancrage par 16 blocs avec alignement de ses
+texels. **Les ombres des blocs restent nettes** : le créateur a écarté leur
+adoucissement après l'essai visuel. Le filtrage est réservé au feuillage.
+Le soleil continue de se déplacer : ce mouvement naturel peut toujours faire
+avancer une ombre d'une case. L'objectif est de supprimer les oscillations
+liées à la caméra, pas de figer le temps.
+
+Entre une élévation solaire de 0,92 et le zénith, l'intensité diminue doucement
+jusqu'à 25 % de sa valeur habituelle : alpha maximal 0,095 au lieu de 0,38.
+La lune réutilise la même carte et son angle natif ; alpha maximal 0,10 selon
+sa phase, nul à la nouvelle lune. Horizon, pluie, portée et brume atténuent
+les deux lumières. Pas de seconde passe de carte lunaire simultanée.
+
+Les blocs du tag vanilla `leaves` projettent une couverture probabiliste fixe
+sur une grille de quart de bloc. Les faces internes restent présentes : plus
+le rayon traverse de couches, moins il a de chances de passer. Il s'agit d'une
+approximation statistique de l'épaisseur, pas d'un comptage des feuilles ni
+d'une lecture des trous de leur texture. Quatre échantillons bilinéaires sur
+un quart de bloc mélangent cette couverture
+en nuances, évaluées sur la grille pixélisée. Un masque R8 distingue feuilles
+et blocs dans la même passe de profondeur, pour garder les silhouettes opaques
+nettes. Les comparaisons suivent le plan récepteur pour éviter l'auto-ombrage
+sur les surfaces obliques. Le motif ne dépend ni du temps ni de la caméra et
+ne demande aucune lecture GPU côté CPU en production.
+Les budgets du cache restent 96 Mio, quatre sections et 3 ms souples par image.
+Le feuillage ajoute des faces ; son filtrage utilise seize comparaisons de
+profondeur et, selon le cas, autant de lectures du masque. Les ombres opaques
+pleines utilisent le chemin court. Le masque prend 4 Mio à la définition
+par défaut, 16 Mio au maximum ; aucune promesse de FPS n'est faite.
+
+Réglages existants et libellés FR/EN conservés/actualisés. Les ombres restent
+optionnelles et désactivées par défaut. Règles, éclairage de gameplay, mondes
+et génération inchangés. Les limitations de beta.127 concernant les entités,
+fluides, verre et autres formes non occultantes subsistent.

+# TOOL-02 — Clé dorée et clé de Steve — beta.123
+
+Contrat du 17 septembre 2026, branche `codex/wrench-safety-beta123`.
+Ce ticket remplace le contrat de la clé dorée de beta.120 : l'édition libre
+reste disponible dans un objet distinct, la **Clé à molette de Steve**.
+Le créateur précise que la clé de Steve reste utilisable en survie dès qu’un
+joueur la récupère, sans condition opérateur. Elle n’a pas de recette.
+
+## Clé dorée : orientations natives
+
+L'identifiant `sanctuary:golden_wrench`, sa recette et sa texture restent stables.
+Clic droit parcourt l'orientation native ; Maj parcourt en sens inverse.
+Clic gauche rappelle les gestes, sans casser le bloc ni sélectionner un état.
+Les familles de propriétés autorisées sont les orientations horizontales,
+les six directions, les trois axes, la rotation native des panneaux et
+l'orientation native des blocs qui la proposent. La règle porte sur les
+propriétés Minecraft, sans catalogue à maintenir pour chaque type de bloc.
+
+L'eau, la moitié d'un escalier, les inventaires, les états de croissance,
+les quantités, la puissance et les autres propriétés ne sont jamais proposées.
+Aucune transformation indépendante des textures n'est créée par la clé dorée.
+Les textures suivent seulement le modèle orienté par Minecraft.
+Les connexions et formes sont recalculées à partir des voisins réels, avec les
+mises à jour natives actives. Une orientation privée de support est refusée
+sans casser le bloc. L'eau déjà contenue dans un bloc est conservée.
+
+Les coffres doubles, portes, lits, étagères reliées, pistons sortis et leurs
+pièces mobiles ne peuvent pas être tournés individuellement. Ils restent dans
+leur état courant et une indication explique le refus. Il faut replacer les
+éléments concernés ou rétracter le piston ; ce ticket ne déplace pas un
+ensemble lié. Les coffres simples conservent leur entité et leur inventaire.
+
+L'assemblage, l'ouverture et la dissociation des Métablis, Fûts, Fourneaux et
+super pistons restent prioritaires avec les deux clés. Les parties techniques
+d'un multibloc Sanctuary assemblé ne sont pas éditées individuellement.
+
+## Clé de Steve
+
+Nouvel identifiant `sanctuary:steve_wrench`, dans la section créative des outils,
+sans recette de survie. La possession de cet objet donne accès à ses pouvoirs,
+y compris en survie sans commandes et sans statut opérateur, dans les deux
+mains. Les restrictions natives de construction, aventure, spectateur, portée,
+protection et verrouillage restent appliquées côté serveur.
+
+Les gestes de beta.120 sont conservés : clic gauche choisit la propriété,
+clic droit la modifie, Maj inverse le parcours. Tous les états natifs et la
+rotation indépendante des textures y restent volontairement accessibles.
+La clé de Steve est donc volontairement capable de produire des états non
+naturels, y compris pour le joueur qui la récupère en survie.
+
+La texture finale est le PNG 16 × 16 bleu fourni par le créateur dans ce ticket,
+copié sans transformation dans `assets/sanctuary/textures/item/steve_wrench.png`.
+SHA-256 : `0084c41e1f46958903075e21866facd97d85e03fb8e06742e25b2ab254956fa3`.
+Le modèle reste un objet Minecraft 2D tenu en main, avec rareté épique et reflet.
+La proposition imagegen intermédiaire n'est pas livrée. Les noms, messages et
+indications des deux outils existent en français et en anglais.
+
+## Sauvegardes et ressources
+
+Aucune migration, modification de génération ni parcours des mondes existants.
+Les transformations de texture précédemment sauvegardées sont conservées ;
+la clé de Steve permet de les modifier. Les états non naturels déjà présents
+ne sont pas automatiquement réécrits. Les clés dorées existantes reçoivent
+immédiatement les nouvelles restrictions par leur identifiant inchangé.
+Le template personnel inclut le nouvel objet à sa prochaine création ; une
+copie personnelle existante n'est jamais écrasée.
+
+## Vérifications
+
+Le parcours `Wrench123ClientChecks` passe en **1 min 12 s**, client macOS et
+serveur intégré, Minecraft 26.3, dans des mondes plats jetables de graines
+123 et 120. Il reprend le parcours avancé de beta.120 sur la clé de Steve :
+
+- Vrais clics dorés répétés sur escalier, coffre et terre : pas de nouvelle eau,
+  pas de sélection libre, pas de faux coffre double ni de rotation de texture.
+- Rotation inverse, eau existante conservée, formes recalculées selon les voisins,
+  trois axes de bûches et six orientations des pistons isolés.
+- Coffre double avec ses deux inventaires intacts ; portes, lits, pistons sortis
+  et pièces mobiles protégés ; torche murale sans support laissée intacte.
+- Vrais clics Steve en survie sans commandes : états et textures accessibles,
+  dans les deux mains. Créatif accessible aussi sans commandes ; restrictions
+  aventure/spectateur/portée conservées.
+- **2 522 propriétés natives** toujours réversibles pour Steve, UV réellement
+  tournés sans déplacer la géométrie, rechargement des ressources, inventaires
+  et sauvegarde/reconnexion conservés.
+- Assemblage et dissociation des quatre familles avec la clé dorée par vrais
+  clics ; le PNG de Steve apparaît en main et dans la barre rapide.
+
+Marqueurs `WRENCH123_SAFE_PASS`, `WRENCH123_PASS`, `WRENCH120_PASS` dans
+`build/wrench123-client.log`. Captures relues dans `build/wrench123-evidence/`.

+notamment les sculptures et la texture dorée, sont identiques.
