+# 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.
+

+## 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.

+# 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.
+
+## Vérifications
+
+Le parcours natif `Sculpture125ClientChecks` passe en **1 min 2 s**, client
+Minecraft 26.3 sur macOS et serveur intégré jetable (graines 125 et 122).
+
+- 54 clics réels sur les six faces : centres, bords, coins et hauteurs.
+- 432 contextes de pose, coordonnées positives/négatives, quatre orientations,
+  rotations et miroirs ; 144 états valides.
+- 20 anciens états sans `vertical_anchor` conservent leur hauteur et marges.
+- Couleur exacte des éclats au point frappé, surfaces réellement occupées,
+  limite de 64 fragments, événement après suppression et particules normales
+  d'un bloc de pierre témoin.
+- Atelier : découvertes par rencontre, victoire et mort, transmission native
+  du menu, refus serveur d'une espèce inconnue, trois modèles natifs (vache,
+  mouton, cochon), paiement d'un bloc en survie et import GLB conservé.
+- Sauvegarde et reconnexion avec les nouveaux coins et hauteurs.
+- 576 formes comparées aux limites du maillage affiché, boîte unique partagée,
+  cache réutilisé et 12 arêtes ; 9 216 empreintes orientées sur grille entière.

+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.

+# 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

+# 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
+le rendu des minerais/du soleil sont inspectés.

+# SHADER-131 — émissifs indépendants et réglages initiaux
+
+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.
+
+Le futur effet demandé est une légère teinte diffusée depuis les blocs
+voisins, pas des reflets reconnaissables. Étude seulement pour ce ticket ;
+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.
+
+## Vérifications
+
+Suite client native réussie en **3 min 46 s**, monde plat neuf de graine 122,
+macOS / Apple M1 / OpenGL. Cinq précisions sauvegardées et chargées, bornes
+et seuils de normalisation, carte d'ombres plafonnée et arêtes CTM rendues
+à 64/128. Le gain mesuré des traits diminue de 0,02778 à précision 32 à
+0,02094 à 64, puis 0,01013 à 128 dans la même scène.
+
+Les inclusions restent nettes sans halo : le rendu Bloom OFF correspond
+au rendu intensité zéro. Aucun gain mesuré hors du masque source, ressources
+de diffusion absentes ; couper aussi les émissifs libère l'ensemble et
+restitue l'image initiale. Réactiver le bloom restitue son image précédente.
+Captures OFF/zéro inspectées. Valeurs initiales ON vérifiées ; un ancien
+choix explicitement OFF reste OFF. Les essais beta.130 (vingt masques,
+occultation, sources, rechargement), lune, feuillage et realtime passent.
+
+Le premier essai rencontrait une assertion historique attendant le highlight
+OFF lorsqu'une clé était absente. Elle attend désormais la nouvelle valeur
+ON ; les cas de préférences explicitement désactivées restent testés.

+
+## 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.
