+# 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
+les archives sont vérifiés séparément avant publication.
+
+
+Build final `./gradlew check build assemblePack assembleTestPack
+-x :sanctuary:runGameTest` réussi en **2 min 10 s**, 126 tâches. Les contrôles
+natifs de gameplay précèdent uniquement le remplacement final des deux PNG
+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.

+# 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 \
+  -PsanctuaryClientNoVsync=true -PsanctuaryQuickTests=true
+```
+
+Succès en **1 min 17 s**, marqueur `PIXEL_SHADOWS122_CLIENT_PASS` dans
+`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.
+Reçu : `build/pixel-shadows122-artifact.json`.

+`66987681cede1d2adc1dda449078e8fa85310eb2c3fecd7a905d772ce75739c9`.
+
+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.

+avait échoué dans l'aperçu du test qui créait un ItemStack avant connexion à
+un monde ; cet aperçu affiche maintenant directement la texture résolue.

+aux deux nouvelles classes, au hook d'interface, aux libellés et aux ressources
+prévues (12 entrées). Aucun changement de gameplay, de données serveur ou de
+monde. Les packs normal/Test contiennent le même JAR Sanctuary, sans fixture
+ni sauvegarde. Le ZIP du template et l'export natif ont exactement les mêmes
+1 202 fichiers et empreintes. Le pack intégré conserve ses 151 fichiers vérifiés.

+# 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.
+
+## Vérifications
+
+Le parcours `Sculpture122ClientChecks`, adapté au nouveau contrat, passe en
+**39 s** sur Minecraft 26.3, client macOS et serveur intégré jetable de graine 122.
+
+- Sélection native de tout le volume, y compris le trou visuel d'une arche ;
+  contour rectangulaire relu dans la capture.
+- Même boîte physique et de sélection sur client et serveur ; intérieur rempli,
+  dimensions exactes sans profondeur artificielle de bloc entier.

+  Arche, marges vides, cube de 4 096 cellules et voxel unique, dans les quatre
+  orientations et cinq ancrages.
+- **5 120 placements** de rendu toujours alignés sur la grille entière.
+- Pose refusée dans le joueur, y compris entre deux piliers séparés ; petite
+  sculpture autorisée à côté du joueur, hors de sa boîte physique.
+- Cache renouvelé après changement d'orientation/ancrage ou de modèle ;
+  conservation après sauvegarde/reconnexion.
+- **75 sculptures superposées** : ciel à 15 ; toit de pierre témoin sombre ;

+# 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.
+Libellés FR et EN.

+# 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 :

+  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).

+# SHADER-127 — intégration des ombres portées pixélisées
+
+Demande du 17 septembre 2026 : livrer le shader dans **beta.127**.
+Branche `codex/shader-beta127`, socle publié beta.126, Minecraft 26.3 / Java 25.
+
+La préparation locale [des ombres pixélisées](pixel-shadows-source122.md) est
+intégrée sans écraser les changements non publiés du dossier d'origine.
+Les gemmes, dernières textures de rubis/saphir, l'argile spéciale et les
+commandes de découverte de beta.126 sont conservées.
+
+## Utilisation
+
+**Options → Shaders → Sanctuary · Vanilla Light → Ombres portées pixélisées**.
+L'option est désactivée par défaut ; son activation reste un choix du joueur.
+Finesse : 8/16/32 pixels par bloc ; portée : 16/32/64 blocs. Défauts : 16 et 32.
+Les paramètres FR/EN s'appliquent immédiatement et persistent dans
+`config/sanctuary-shaders.json`. La mise à jour préserve les réglages personnels.
+Le rendu est natif au mod : aucun pack Iris, téléchargement supplémentaire ou
+nouvelle dépendance de rendu.
+
+## Périmètre
+
+Ombres solaires des formes d'occultation des blocs chargés, incluant dalles,
+escaliers et obstacles hors écran. Carte de profondeur GPU, grille ancrée dans
+le monde, atténuation selon soleil, pluie et brume. L'effet s'arrête la nuit,
+dans les dimensions sans soleil, dans les fluides ou avec un moteur externe.
+Le HUD et la main ne passent pas dans cet effet. La lumière de gameplay,
+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.
+
+## Vérifications et livraison

+- Pilier hors écran : 42 048 échantillons restent ombrés ; le retrait du pilier
+  restitue la lumière sur les 42 048 et conserve les 23 616 déjà éclairés.
+  La repose rétablit la même ombre sans désactiver le cache.
+- Trois finesses et trois portées, redimensionnement GPU, désactivation/libération,
+  arrêt nocturne, reprise diurne et rechargement des ressources vérifiés.
+- Préférences persistantes et bornées ; captures FR/EN inspectées, sans texte
+  tronqué. La scène pilier/dalle/escalier est également inspectée visuellement.

+# 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.

+# SHADER-129 — arêtes connectées et portées étendues
+
+Demandes du 17 septembre 2026 : highlight optionnel, puis raccordement CTM de
+tous les blocs coplanaires, portée indépendante 16–256 blocs, ombres à 128/256,
+suppression de l'atténuation au zénith et du réalignement cyclique des ombres.
+Branche `codex/edge-highlights-beta129`, socle beta.128, Minecraft 26.3 / Java 25.
+
+## Résultat
+
+Dans **Options → Shaders → Sanctuary · Vanilla Light**, les reflets sur les
+arêtes sont désactivés par défaut. L'intensité va de 0 à 100 ; la valeur 30
+éclaircit au maximum de 12 %. Leur portée se règle indépendamment des ombres :
+**16, 32, 64, 128 ou 256 blocs**. Les anciens réglages restent conservés.
+
+Le highlight raccorde les surfaces plates, y compris entre matériaux différents,
+sans dessiner les jonctions intérieures. Il suit les contours visibles du relief,
+y compris les dalles et escaliers. Il multiplie la couleur existante pour garder
+les pixels des textures et composer avec les ombres. Ce CTM géométrique utilise
+la profondeur déjà produite par Minecraft : aucune liste de blocs autorisés,
+aucun pack CTM à fournir, aucune exploration CPU du volume de 256 blocs.
+Une cassure/repose modifie le contour dès que le terrain natif est réaffiché.
+
+Le trait proche suit la grille de 1/16 de bloc. À distance, la couverture devient
+partielle pour limiter le scintillement des traits plus petits qu'un pixel.
+La portée choisie s'efface progressivement dans son dernier quart et respecte
+la brume ainsi que la distance de rendu. Une passe plein écran, quatre sondes
+de profondeur et un tampon uniforme de 176 octets ; aucun retour GPU vers CPU
+en production. L'arrêt de l'option ou une intensité nulle libèrent ce tampon.
+
+Ce n'est pas un remplacement des textures par des variantes CTM. Le calcul
+concerne les faces visibles alignées sur la grille : les faces hors écran,
+les surfaces transparentes absentes de la profondeur et les géométries
+arbitrairement inclinées ne sont pas reconstruites. À très grande distance,
+les détails plus petits qu'un pixel peuvent rester imperceptibles. Aucun
+chargement de chunk forcé, aucune promesse de FPS.
+
+Les ombres proposent les cinq mêmes portées. La carte reste plafonnée à
+4096 × 4096 : les grandes distances réduisent sa précision spatiale. Le cache
+garde ses limites de 96 Mio, quatre sections et 3 ms souples de construction
+par image ; la réconciliation des chunks est limitée aux ticks et changements
+de caméra/terrain plutôt qu'à toutes les images.
+
+L'intensité solaire reste pleine au zénith. Les contours opaques restent nets,
+le filtrage du feuillage et les ombres légères de la lune sont conservés.
+Le réalignement de la grille lumineuse a lieu au changement d'ancrage de la
+caméra, avec transfert de phase par texels entiers. La rotation du soleil ne
+réarrondit plus la projection de l'origine mondiale à chaque image, source
+de sauts périodiques amplifiés aux grandes coordonnées. Le soleil continue
+d'avancer ; une ombre pixélisée peut naturellement changer de case. Cette
+correction ne modifie pas l'horloge serveur ni sa cadence native.
+
+Textes FR/EN. Aucun changement de règles, sauvegardes, génération, gemmes,
+sculptures ou découvertes.
+
+## Vérifications et livraison
+
+Le client natif réussit en **2 min 41 s**, dans un monde neuf plat, graine 122,
+sur macOS / Apple M1 / OpenGL :
+
+- CTM : 596 échantillons éclaircis sur le contour et 65 068 conservés ; les
+  20 centres et 20 jonctions coplanaires ciblés restent intacts, y compris
+  au changement de matériau. L'intensité 90 produit environ trois fois le gain.
+- Ouverture d'un trou : 716 échantillons éclaircis ; la fermeture restitue
+  l'image connectée. Au-delà de 16 blocs, le réglage 16 supprime le contour ;
+  le réglage 64 le rétablit (254 échantillons éclaircis).
+- Cinq portées CTM et cinq portées d'ombres, persistance/clamp, migration des
+  anciennes préférences, arrêt/libération, rechargement, caméra et vue oblique
+  avec ombres. Captures françaises/anglaises inspectées ; suppression ensuite
+  d'un préfixe redondant dans le libellé de portée.
+- Soleil, lune, nouvelle lune, ombres opaques nettes à midi et transmission
+  du feuillage restent vérifiés. Casters hors écran et retrait/repose actifs.
+- 2 000 petits pas solaires aux coordonnées ±100 000 vérifient l'absence de
+  saut de translation de la carte ; changement d'ancrage par texels entiers.
+  La séquence du vrai service realtime suit 294 images : angle avancé de
+  0,000694 radian, aucun rebond dans les 65 664 échantillons de sol suivis.
+  Sur cette courte séquence, aucune case opaque n'a changé ; cela ne constitue
+  pas une mesure de mouvement visible sur une journée entière.
+
+La fixture initiale capturait parfois le terrain avant la fin de sa construction
+native : elle attend désormais la réception de toute la plateforme et la fin
+compilée des sections. Aucun changement de gameplay pour contourner ce problème.

+# SHADER-130 — bloom et précision commune
+
+Demandes du 17 septembre 2026 : bloom réglable du soleil et des sources
+lumineuses ; inclusions émissives du fer, cuivre, redstone, lapis, diamant,
+émeraude, rubis, saphir, quartz et or ; réglage commun « Précision » pour
+les ombres et le highlight. Branche `codex/bloom-beta130`, socle beta.129,
+Minecraft 26.3 / Java 25.
+
+## Résultat
+
+Dans **Options → Shaders → Sanctuary · Vanilla Light**, le bloom possède
+un interrupteur, une intensité et une diffusion réglables de 0 à 100.
+Les minerais ont leur propre interrupteur et intensité. Le bloom reste
+optionnel, désactivé initialement, avec une intensité préparée à 35, une
+diffusion à 50 et une émission des minerais à 50. Une intensité globale
+nulle arrête les passes et libère les ressources de cet effet.
+
+Les nouveaux réglages par défaut sont **Pixel Shadows activé**, distance
+des ombres **128 blocs**, highlight **32 blocs** et **Précision 16 pixels
+par bloc**. La précision unique propose 8, 16 et 32 et contrôle simultanément
+ombres et arêtes. La clé JSON historique `shadowPixels` est conservée :
+les préférences déjà personnalisées ne sont pas écrasées.
+
+Les vingt textures de minerais sont analysées depuis les ressources actives.
+La palette de pierre, de deepslate ou de netherrack est comparée aux pixels
+colorés des inclusions, avec un traitement du quartz et de l'or du Nether.
+Les reflets clairs accolés aux inclusions sont conservés. Le masque est
+calculé une fois par texture et conservé en cache jusqu'au rechargement des
+ressources. Une texture optionnelle `<nom>_e.png` peut préciser ce masque
+pour une texture candidate ; sa luminance maximale multipliée par l'alpha
+remplace la détection automatique. Les couleurs affichées viennent toujours
+de l'atlas Minecraft actif, y compris son animation.
+
+Les sources sont les faces visibles des modèles de blocs lumineux, la lave,
+le soleil et la lune. Les lampes éteintes ne produisent pas de halo. Le
+niveau lumineux natif pondère les sources ordinaires ; l'émission des minerais
+est purement graphique. La profondeur du terrain élimine les inclusions
+cachées et masque le soleil derrière les constructions. Le cœur émissif
+conserve ses pixels nets, tandis qu'un halo séparé est diffusé à résolution
+réduite puis composé sur l'image.
+
+Aucun niveau de lumière serveur, spawn, règle de jeu, format de sauvegarde,
+identifiant ou paramètre de génération ne change. Aucun monde personnel
+n'est ouvert pour les essais.
+
+## Coût et limites
+
+La géométrie suit uniquement les sections natives visibles et déjà chargées.
+Leur palette permet d'écarter rapidement les sections sans source ; le cache
+invalide les sections touchées lors des modifications. Construction répartie
+sur les images, au plus quatre sections démarrées et un budget souple de
+3 ms, cache GPU plafonné à 32 Mio et 16 384 faces par section. Une section
+qui dépasse les limites est omise. Aucun chargement de chunk forcé.
+
+Le masque GPU est plafonné à 256 textures, chacune échantillonnée au plus en
+64 × 64 ; les textures natives 16 × 16 conservent leurs texels. Les masques
+animés utilisent leur première image, tandis que la couleur reste animée.
+La carte d'émission est à la résolution de l'écran ; la diffusion séparable
+utilise deux cibles flottantes à 1/8 de largeur et de hauteur, sans retour
+GPU vers CPU en production. Les allocations sont libérées à l'arrêt, au
+rechargement et à la déconnexion, et recréées au changement de taille.
+
+Cette première version ne reconstruit pas les sources hors écran, les
+particules, les entités lumineuses ni les modèles dessinés exclusivement par
+un renderer de block entity. Les packs très différents peuvent demander un
+masque explicite. Les silhouettes des liquides sont approximées puis
+masquées par la profondeur native. Aucune promesse de FPS ni validation
+Windows/Vulkan ; les essais graphiques portent sur macOS / Apple M1 / OpenGL.
+
+## Vérifications
+
+Le test client ciblé réussit en **1 min 29 s**, dans un nouveau monde plat,
+graine 122. Il analyse les vingt textures, refuse les pixels gris de leur
+roche, mesure le gain nocturne et les variations réelles d'intensité/diffusion.
+Couvrir les minerais de pierre supprime toute source émissive. Retirer les
+blocs rétablit l'émission ; le rechargement des ressources fait de même.
+Torche, glowstone, lampe alimentée, lave et soleil sont vérifiés, ainsi que
+l'arrêt de la lampe et l'occultation du soleil par de la pierre. Les valeurs
+par défaut et la conservation d'anciens choix personnalisés passent.
+
+Log ciblé : `build/shader130-client-bloom.log` ; masques inspectables dans
+`mods/sanctuary/build/run/clientGameTest/bloom130-ore-masks.png` et son CSV.
+La suite shader complète réussit en **3 min 16 s** : casters hors écran,
+retrait/repose, trois précisions, cinq portées, lune, zénith, feuillage,
+realtime, caméra et rechargement restent vérifiés. Les arêtes CTM restent
+raccordées entre matériaux ; 1 295 échantillons du contour sont éclaircis
+à précision 8, 596 à 16 et 120 à 32. Les captures françaises/anglaises et

+Demande : activer par défaut bloom, minerais émissifs et highlight ; garder
+les émissifs avec halo coupé ou intensité du bloom à zéro, sans bouton ajouté ;
+ajouter 64 et 128 pixels/bloc en options. Précision initiale 16, distances
+highlight 32 et ombres 128 conservées. Préférences personnalisées préservées.
+Branche `codex/emissive-beta131`, socle beta.130, Minecraft 26.3 / Java 25.

+aucun SSR ou éclairage indirect expérimental activé.
+
+## Comportement et validation
+
+Le curseur à zéro et l'interrupteur Bloom coupent uniquement le halo.
+Le réglage existant des minerais contrôle leurs inclusions nettes séparément.
+Sans halo, les cibles de diffusion GPU sont libérées ; l'émission garde
+seulement les ressources nécessaires. Tout désactiver libère l'ensemble.
+La grille commune propose 8, 16, 32, 64 et 128, sans augmenter le plafond
+4096 de la carte d'ombres. Libellés FR/EN et essais clients natifs sur les
+inclusions, l'absence de halo, les transitions et les nouvelles précisions.
+Aucun changement de lumière serveur, de génération ou de sauvegardes.
+
+Le cœur émissif et le halo utilisent maintenant deux chemins indépendants.
+Les textures et leur analyse restent celles de beta.130. Avec le halo coupé,
+la carte d'émission est effacée avant les faces, le cœur net est composé,
+et les passes de ciel, réduction, diffusion et application du halo sont
+omises. Le retour au bloom recrée ses cibles. Aucun bouton ajouté, aides
+FR/EN adaptées et choix explicitement désactivés toujours conservés.

+## Piste suivante — diffusion des couleurs
+
+Choix confirmé : légère teinte des surfaces voisines. Une estimation SSGI

+la [documentation primaire Unity](https://docs.unity3d.com/Packages/com.unity.render-pipelines.high-definition@17.0/manual/Override-Screen-Space-GI.html).
+Proposition à expérimenter : faible intensité, courte portée autour des
+surfaces, calcul réduit, rejet par profondeur pour ne pas teinter au travers
+des murs. Vérifier les bords de l'écran, les blocs hors champ, la stabilité
+en mouvement et les textures avant de fixer une qualité. Cette piste n'est
+pas implémentée dans beta.131.

+# SHADER-132 — diffusion locale SSGI expérimentale
+
+Demande : légère teinte diffusée des surfaces voisines, sans reflets miroir
+ni shader d'eau. Branche `codex/ssgi-beta132`, socle beta.131, Minecraft 26.3 /
+Java 25. Aucun changement de génération, sauvegarde ou lumière serveur.
+
+## Résultat
+
+**Options → Shaders → SSGI · couleurs diffusées** active un rebond diffus
+local. L'effet expérimental est initialement OFF, avec une intensité préparée
+à **35 %** ; le curseur propose 0–100. À zéro ou OFF, ses cibles et uniformes
+GPU sont libérés. Les autres effets et leurs préférences sont conservés.
+
+La couleur d'une surface visible peut teinter les surfaces proches qui lui
+font face. Le calcul porte à **2,5 blocs** du récepteur et s'estompe entre
+24 et 32 blocs de la caméra. Il utilise une copie de la couleur native après
+les ombres, avec la profondeur et des normales reconstruites. Le premier
+obstacle arrête chaque rayon, même si son épaisseur empêche de retenir une
+intersection. Les plans coplanaires ne s'éclairent pas eux-mêmes.
+
+Douze directions hémisphériques fixes, au maximum dix étapes par rayon,
+sont évaluées à demi-résolution en largeur et hauteur. La reconstruction
+plein écran est guidée par la profondeur pour conserver les silhouettes et
+les détails des textures. Le cœur des émissifs, le highlight et le bloom
+sont composés ensuite : pas de halo réinjecté dans le rebond ni de boucle
+de rétroaction d'une image sur l'autre. Aucune lecture GPU vers CPU ni
+recherche de chunks en production. Pas de bruit temporel ou d'historique.
+
+Deux cibles, RGBA8 plein écran et RGBA16 flottant à demi-résolution, soit
+environ six octets par pixel de l'écran, plus 176 octets d'uniformes par
+segment du tampon natif. Redimensionnement, arrêt, déconnexion et
+rechargement libèrent/recréent les ressources possédées. Ce budget n'est
+pas une garantie de FPS ; le SSGI coûte davantage qu'un simple réglage de
+colorimétrie.
+
+## Limites de cette version
+
+L'estimation utilise seulement la couleur et la profondeur visibles. Les
+blocs hors champ ou cachés n'apportent pas leur couleur. Le résultat peut
+changer lorsqu'ils entrent ou sortent de l'image ; une atténuation près
+des bords limite la coupure. Les surfaces transparentes absentes de la
+profondeur ne sont pas reconstruites. Petits objets et intersections plus
+minces que l'échantillonnage peuvent manquer. Il s'agit d'une approximation
+diffuse locale, pas d'une simulation complète d'éclairage global ni de
+reflets spéculaires. Aucune modification de l'eau et aucune source hors
+champ déduite ou générée.
+
+## Vérifications
+
+Test ciblé natif réussi en **1 min** sur macOS / Apple M1 / OpenGL, nouveau
+monde plat de graine 122. À intensité 90, les échantillons du sol blanc
+montrent un gain rouge cumulé de 8 968 contre 20 bleu devant le mur rouge,
+puis 9 168 bleu contre 23 rouge devant le mur bleu. Le sol seul est inchangé.
+OFF/zéro restituent l'image de base et libèrent les cibles ; intensité 20
+réduit le gain. Changer la couleur du mur complètement occulté laisse
+l'image inchangée. Rechargement, caméra fixe, mouvement infinitésimal et
+retour à la caméra d'origine passent, sans accumulation de couleur.
+
+Deux ajustements de fixture ont précédé ce résultat : inclure dans les
+mesures le blanc légèrement bleuté par l'éclairage natif, et formater les
+petits angles de `/tp` en décimal car la commande refuse la notation
+scientifique. Aucun comportement du jeu modifié pour ces corrections.
+
+Log ciblé : `build/shader132-client-ssgi.log`. La suite complète réussit en
+**4 min 18 s** et vérifie aussi une fenêtre 961 × 541, le retour à sa taille

+l'arrêt global du shader. Les captures françaises et anglaises passent.

+# SHADER-133 — SSGI visible au réglage courant
+
+Demande : le rebond diffus de beta.132 est trop discret pour être distingué.
+Branche `codex/ssgi-strength-beta133`, socle beta.132, Minecraft 26.3 / Java 25.
+
+## Changement
+
+La collecte conserve douze directions, dix étapes, une demi-résolution et
+un rayon de 2,5 blocs. L'atténuation spatiale devient linéaire plutôt que
+quadratique. Le mélange est reconstruit en lumière approximativement linéaire,
+puis réencodé une seule fois. Un gain artistique plus fort rend la couleur
+lisible et une courbe progressive évite de couper brutalement les canaux
+à blanc. Les surfaces sans rebond restent intactes. La force demeure réglable
+de 0 à 100, avec le même réglage initial de 35 ; aucune préférence enregistrée
+n'est écrasée. SSGI reste optionnel, initialement désactivé.
+
+Aucun rayon, cible GPU ou texture de matériau supplémentaire. La composition
+ajoute une exponentielle et une racine carrée par canal ; le coût exact en FPS
+reste à mesurer sur la machine du joueur. Les normales de géométrie orientent
+déjà le rebond. Pas de PBR ni de normales procédurales de textures ajoutés.
+
+## Piste matériaux
+
+Pour une étape distincte, des normales de faible amplitude calculées au
+chargement des textures, mises en cache, et une rugosité par famille de matériaux
+permettraient d'étudier du relief et des reflets orientés. Une simple conversion
+luminosité → hauteur ne connaît pas le relief réel : un motif peint peut devenir
+une bosse artificielle. Commencer sur pierre, briques et bois avec une amplitude
+réglable serait préférable à une génération aveugle pour tous les blocs.
+La passe actuelle ne possède ni atlas de normales, ni identifiants de matériaux,
+ni albédo non éclairé ; des images seules ne suffiraient pas à les exploiter.
+
+## Limites conservées
+
+Approximation diffuse à partir de la couleur déjà éclairée, pas un transport
+physique complet. Seules les surfaces visibles contribuent, avec variations
+possibles aux entrées/sorties d'écran. Premier obstacle bloquant, pas d'historique
+ni de bruit temporel ; aucune modification d'eau, monde ou lumière serveur.
+
+## Vérifications
+
+Suite client native complète réussie en **4 min 29 s**, sur macOS / Apple M1 /
+OpenGL, dans un monde de test plat (graine 122). Les comparaisons ON/OFF à 35 %
+mesurent, sur les pixels neutres du sol :
+
+| Mur | Pixels avec gain ≥ 8/255 | Pixels avec gain ≥ 16/255 | Gain cumulé du canal dominant |
+| --- | ---: | ---: | ---: |
+| Rouge | 16 487 | 7 311 | 305 221 |
+| Bleu | 14 954 | 7 328 | 309 991 |
+
+À 90 %, les gains dominants atteignent 654 683 et 655 867, contre 8 968 et
+9 168 au même réglage dans la fixture beta.132. Ce rapport concerne uniquement
+cette scène et ces pixels, pas une promesse de gain uniforme dans tous les mondes.
+Les captures confirment une bande colorée au pied du mur. Un premier réglage
+intermédiaire a été rejeté car aucun pixel du sol ne dépassait 8/255 à 35 % ;
+un second a passé les contrôles ciblés, puis la force a encore été augmentée
+après examen visuel. Les valeurs finales sont celles de la suite complète.
+
+Le test impose maintenant plus de 5 000 pixels à 8/255 et plus de 500 à 16/255
+au réglage 35, pour les deux couleurs. Intensité, OFF/zéro, absence de rebond
+coplanaire, occultation d'un mur changeant de couleur, caméra fixe, déplacement
+infinitésimal, retour de caméra, redimensionnement et rechargement passent.
+Ombres, lune, feuillage, CTM, cinq précisions, bloom, émissifs indépendants et
+interfaces FR/EN restent validés, y compris avec le SSGI actif.

+# SHADER-134 — PBR procédural optionnel et herbe SSGI
+
+Demande : ajouter en option des normales calculées à partir des textures actives,
+avec rugosité des matériaux et reflets orientés. Retour : le SSGI renforcé
+éclaire artificiellement l'intérieur de l'herbe ; vérifier et corriger ce cas.
+Branche `codex/pbr-beta134`, socle beta.133, Minecraft 26.3 / Java 25.
+
+## Contrat
+
+PBR initialement OFF, intensité 50 réglable 0–100. Cartes de normales à partir
+des différences de luminance, amplitude limitée ; rugosité/métallicité par
+famille de blocs, repli rugueux pour les types inconnus. Analyse des ressources
+actives conservée en cache jusqu'à désactivation ou rechargement ; pas de fichiers
+écrits dans le pack personnel, pas de GPU readback en production.
+
+Portée 32 blocs, sections visibles construites progressivement. Budget de maillage
+24 Mio, atlas de 4 096 matériaux en 16 × 16 avec bordures (1 280 × 1 280 RGBA8,
+6,25 Mio), copie RGBA8 de l'image courante et uniformes. Les textures de plus haute
+résolution sont échantillonnées à 16 × 16 ; première image des textures animées.
+La couleur et l'animation restent celles de l'atlas natif. Pas de parallax ni
+de géométrie ajoutée aux blocs ; les motifs clairs peuvent donner un faux relief.
+
+La passe utilise une réponse spéculaire GGX (normales, rugosité, métallicité,
+Fresnel) et module l'éclairage diffus déjà rendu. Elle ne remplace pas tout le
+pipeline Minecraft par un moteur PBR physique. Soleil/lune, exposition au ciel et
+carte d'ombres active limitent les reflets ; pas de reflets miroir, d'environnement
+SSR, ni de direction locale déduite pour chaque torche. Aucun rendu PBR d'eau,
+d'entités, d'items ou de modèles spéciaux hors maillage de terrain.
+
+## SSGI
+
+Les normales des faces presque axiales sont stabilisées sur leur axe. Deux passes
+spatiales filtrent la lumière indirecte à demi-résolution, avec rejet des voisins
+hors du plan du récepteur et interpolation de l'échantillonnage. Les textures de
+l'image restent nettes. Un tampon RGBA16F supplémentaire à demi-résolution porte
+le budget des cibles SSGI à environ 8 octets par pixel plein écran (contre 6).
+Pas d'historique temporel ni de rémanence ajoutés.
+
+Un parcours de 12 blocs a reproduit des bandes sur un mur et un éclaircissement
+artificiel d'herbe à 35 et 100. Le filtrage seul ne suffisait pas : la collecte
+réinjectait aussi trop fortement la lumière ambiante neutre. Elle conserve
+maintenant la composante chromatique de la source, en soustrayant son canal
+linéaire minimum. L'éclairage ambiant neutre reste celui de Minecraft. Ce réglage
+vise le transfert de couleur voulu, pas une simulation physique complète du
+rebond blanc. Les sources hors champ/cachées restent absentes du SSGI ; le résultat
+peut encore varier lors d'un déplacement important. PBR et SSGI restent indépendants.
+
+## Vérification
+
+Test PBR ciblé réussi en 1 min 13 s : relief éclairé/ombré, intensités 20/50/100,
+soleil matin/soir, cache stable, préférences, OFF/zéro, mouvement infinitésimal,
+redimensionnement, rechargement et combinaison des effets. Le premier parcours
+SSGI est conservé comme reproduction ; résultats finaux ci-dessous.
+
+
+Le parcours corrigé a réussi en **2 min 47 s** avec 13 positions réparties sur
+12 blocs, à 35 et 100, chaque fois comparées à OFF. Un mob immobile, des brins
+d'herbe et un mur figurent dans la scène. Retour au point initial sans rémanence.
+Sur les captures de ce parcours, le maximum du gain vert moyen mesuré dans
+l'herbe passe sous 9,73 niveaux à 35 et 24,51 à 100. Le test impose ensuite
+respectivement des limites de 12 et 30 à chaque position. L'essai reproduisant
+le défaut atteignait notamment 23,68 et 49,20 à l'extrémité droite.
+Ces mesures décrivent cette scène, pas une garantie d'absence d'artefacts
+dans tous les mondes ni sur toutes les cartes graphiques.
+
+
+La suite client complète réussit en **7 min** sur macOS / Apple M1 / OpenGL.
+Elle inclut le parcours latéral et ses seuils de gain, les deux couleurs de rebond,
+le PBR, les ombres, le feuillage, les cinq précisions, le CTM, les émissifs, le
+bloom, les préférences et les écrans FR/EN. Log : `build/shader134-client-full.log`.
+Le contrôle PBR final réussit en **1 min 19 s** : placement/retrait d'un toit,
+invalidations de lumière/maillage et rendu combiné avec les ombres actives. Les
+reflets utilisent maintenant la grille des ombres pour leur test de visibilité. Aucun résultat Windows/Vulkan ni
+mesure de FPS revendiqués.

+# SHADER-135 — SSGI en contre-plongée et près des surfaces
+
+Demande : supprimer les déchirures horizontales sous une surface, notamment
+près de la lave, et atténuer proprement le rebond quand la caméra s'approche
+d'une source ou d'un mur. Branche `codex/shader-closeup-beta135`, socle beta.134.
+Minecraft 26.3 / Java 25 ; aucune modification de monde ou de gameplay.
+
+## Diagnostic et correction
+
+Le calcul des normales comparait l'aire du pixel en unités du monde à un seuil
+fixe. À courte distance ou à haute résolution, cette aire devient naturellement
+très petite : le rejet pouvait couper une surface continue. Les deux directions
+sont maintenant normalisées avant leur produit vectoriel. Les texels de bord
+sont bornés et les voisins sans profondeur ne créent plus de fausse surface.
+
+La composition utilise le centre exact du texel de profondeur. Le rebond
+s'atténue entre 0,4 et 0,06 bloc de distance au **plan** receveur, et lorsque la
+vue devient presque tangente. Cette distance évite une découpe circulaire sur
+un mur plat. L'image native reste nette ; aucune texture du décor n'est floutée.
+
+Les sondes sortant du volume de projection sont rejetées. Leur contribution
+s'atténue près du plan de caméra et de la limite d'épaisseur d'un impact, au lieu
+d'une contribution pleine jusqu'à cette limite. Trois ressources GLSL modifiées ;
+aucune passe, cible GPU, lecture CPU, histoire temporelle ou option ajoutée.
+Les 12 rayons × 10 pas et les deux passes de filtrage spatial restent inchangés.
+
+## Réglages initiaux
+
+Demande ajoutée pendant la livraison : **bloom 20 %**, **PBR ON** et **SSGI ON**.
+Les intensités PBR 50 et SSGI 35 restent inchangées. Les champs absents du fichier
+de préférences prennent ces nouvelles valeurs ; les choix explicites du joueur
+restent conservés. Aides françaises et anglaises mises à jour. Vérification
+native supplémentaire des préférences vierges, partielles et personnalisées.
+
+## Reproduction native
+
+Deux scènes isolées : stone au-dessus de la lave, puis coin à 0,5 bloc d'une
+paroi rouge. Caméra en contre-plongée, sept distances au plafond de 2 à 0,04 bloc,
+comparaisons OFF/35/100 avant/après. Dans la première scène, à 0,1 bloc et
+intensité 100, le saut maximal de gain rouge moyen entre lignes de pixels neutres
+passe de **14,88 à 0,052** niveaux sur 255. Dans le coin, à 0,4 bloc et intensité
+35, le rebond auparavant rejeté revient (gain moyen de **6,01** niveaux), puis
+s'atténue à l'approche du contact. Ces chiffres concernent ces scènes uniquement.
+
+Les deux essais ciblés corrigés réussissent en 1 min 18 s et 1 min 17 s sur
+Apple M1 / OpenGL. Images avant/après conservées dans `build/closeup-*` ;
+comparateur autonome `build/Shader-beta.135-comparaison.html`.
+
+## Régression et livraison
+
+Les contrôles natifs de la suite générale réussissent jusqu'au parcours SSGI :
+ombres, lune, feuillage, temps réel, CTM, émissifs/bloom, couleurs de rebond,
+occlusion, réglages, rechargement et déplacement latéral de 12 blocs à 35/100.
+Log : `build/shader135-client-main.log`. La suite n'est pas présentée comme
+entièrement réussie : elle s'est arrêtée sur une attente incorrecte du nouveau
+test, qui demandait du rebond alors que sa source était sortie du champ.
+
+Le scénario corrigé distingue la haute résolution avec source visible de la
+vue très relevée sans source visible. Le bassin possède un fond pour isoler la
+lave des essais suivants ; les particules du scénario précédent sont effacées
+avant la comparaison PBR statique. Une première tentative avait aussi rencontré
+le refus natif de remettre l'horloge à sa valeur actuelle ; la préparation de
+l'heure est désormais répétable. Ces changements concernent uniquement les tests.
+
+Le contrôle final ciblé **réussit en 2 min 52 s** : les deux scènes, 35/100,
+sept distances, 1280 × 720 avec source visible, source hors champ, mouvement
+minuscule, rendu combiné, puis contrôles PBR complets (cache, intensités,
+matériaux, soleil, toit, OFF/zéro, redimensionnement et rechargement).
+Log : `build/shader135-client-final.log` ; marqueurs `SSGI135_CLOSEUP_PASS` et
+`PBR134_PASS`. Les seuils de proximité et PBR sont conservés.
+Le contrôle supplémentaire des nouveaux défauts et du PBR **réussit en
+1 min 16 s** : préférences vierges, champs absents, valeurs personnelles conservées,
+puis rendu PBR et combinaison des effets. Log : `build/shader135-defaults-client.log`.
+`./gradlew check build assemblePack assembleTestPack -x :sanctuary:runGameTest`
+réussit en **2 min 18 s**, 126 tâches. Le serveur GameTest dédié demeure exclu
+conformément au refus EULA antérieur. Les classes des scénarios clients compilent
+aussi après leur isolation explicite des effets activés par défaut.
+Log : `build/shader135-build.log` ; compilation : `build/shader135-test-compile.log`.
+
+## Archives vérifiées
+
+Comparaison à beta.134 : **6 entrées de production** modifiées, limitées aux
+trois ressources SSGI, aux valeurs initiales et aux aides FR/EN. Gameplay et
+textures des gemmes inchangés. Packs normal/Test : JAR Sanctuary identique ;
+archives de sources et template conformes aux sources. Reçu local ignoré :
+`build/shader135-artifact.json`.
+
+
+## Limites
+
+Le SSGI utilise seulement les surfaces visibles : les sources hors champ restent
+absentes et un grand changement de vue peut modifier le rebond. L'atténuation
+proche est volontaire ; ce n'est pas une simulation volumétrique. Le brouillard
+natif de submersion continue de suspendre le SSGI, comme en beta.134. Aucun
+résultat Windows/Vulkan ni mesure de FPS revendiqués.

+# SHADER-136 — Lens flare rectangulaire doux
+
+Demande : ajouter un lens flare avec des rectangles dégradés, exclusivement
+pour le soleil et la lune. Socle beta.135, branche `codex/lens-flare-beta136`.
+Minecraft 26.3 / Java 25. Aucun changement de gameplay ou de monde.
+
+## Contrat
+
+Effet activé initialement à **30 %**, intensité réglable 0–100, indépendant du halo de bloom.
+Rectangles translucides aux bords doux, suivant la position de l'astre à l'écran.
+La visibilité provient de l'image émissive céleste native, avant les blocs :
+les murs masquent l'effet, les sources de terrain ne le déclenchent pas.
+L'astre sortant du champ doit s'atténuer sans sauter sur le bord opposé.
+Pas d'historique, ni lecture GPU vers le CPU, ni texture générée sur disque.
+
+## Rendu et budget
+
+Trois rectangles à dégradé doux par astre : un halo horizontal près de sa
+position et deux reflets plus petits le long de l'axe passant par le centre de
+l'écran. Teinte solaire chaude, lunaire légèrement bleue. Intégration de la
+lumière réellement dessinée par le ciel natif ; phases de lune conservées.
+Atténuation aux bords de l'écran et à l'horizon, sans projection derrière la caméra.
+
+Le masque céleste est mesuré avant l'ajout des émissifs de terrain. Réduction
+vers une texture 2 × 1 RGBA16F (512 échantillons au maximum au total), puis une
+passe de composition avec deux lectures de cette texture et des dégradés analytiques.
+La cible d'émission plein écran existante est réutilisée. Quand seul le flare
+fonctionne, aucun maillage d'émissif de terrain ni tampon de flou n'est construit.
+OFF et zéro libèrent la cible du flare ; les autres effets gardent leur autonomie.
+
+## Vérification
+
+Le scénario client natif réussit en **1 min 52 s** sur macOS / Apple M1 / OpenGL.
+Soleil OFF/30/80, lune et nouvelle lune, mur occultant, source hors champ,
+glowstone exclue, image statique, redimensionnement et rechargement des ressources.
+Le flare reste actif sans bloom ; OFF/zéro libèrent ses ressources. Préférences
+vierges, partielles, personnalisées, bornage et libellés FR/EN vérifiés.
+Les contrôles existants du bloom et des minerais émissifs passent également.
+Log : `build/shader136-client-final.log`, marqueurs `EMISSIVE131_PASS` et
+`LENS_FLARE136_PASS`. Les captures natives restent dans le dossier de tests ; comparatif autonome
+`build/Shader-beta.136-comparaison.html` (soleil OFF/30/80 et lune OFF/30).
+
+Une première tentative s'est arrêtée sur l'attente d'un angle de caméra :
+Minecraft normalise 180° en −180°. Le scénario utilise maintenant un angle
+canonique ; ce changement concerne uniquement le test.
+
+## Limites
+
+Effet optique en espace écran : il s'atténue quand l'astre quitte le champ et
+à l'horizon. Le masque natif du ciel contrôle l'occultation ; la lune reste
+volontairement beaucoup plus discrète. Le brouillard de submersion suspend
+l'effet comme le bloom existant. Aucun essai Windows/Vulkan ni mesure de FPS
+revendiqués.

+# 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.
+

+aux libellés et aux ressources du nouvel objet. Les autres ressources,
+notamment les sculptures et la texture dorée, sont identiques.
