+# 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,
+client macOS et serveur intégré, dans un monde plat jetable de graine 122 :
+
+- Pose par la commande native d'utilisation ; sélection du pilier et visée
+  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).
+- Le rendu reçoit la lumière réelle du monde : 15 au ciel, **0 dans une pièce
+  fermée et obscure**. Aucun rendu artificiellement lumineux.
+- Sauvegarde/reconnexion : modèle, collisions et lumière conservés sur les
+  deux côtés, sans fichier 3D source.

+# 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/`.
+Pas de validation Windows, de client distant ou de shader tiers.
+
+`./gradlew check build assemblePack assembleTestPack -x :sanctuary:runGameTest`
+passe en **2 min 19 s**, 126 tâches (103 exécutées, 23 à jour).
+Les sources des JAR correspondent aux sources du dépôt. La comparaison avec
+beta.122 limite les dix entrées de production modifiées aux classes des clés,
+aux libellés et aux ressources du nouvel objet. Les autres ressources,
+notamment les sculptures et la texture dorée, sont identiques.
+Les packs normal/Test contiennent le même JAR Sanctuary, sans sauvegarde ni
+fixture de test. Le template ZIP correspond exactement aux ressources du JAR
