+# 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.
+
+Commandes natives : `./gradlew :sanctuary:runClientGameTest
+-PsanctuaryClientTests=true -PsanctuaryPixelShadows122ClientTests=true
+-PsanctuaryClientNoVsync=true -PsanctuaryQuickTests=true`. Le test ciblé utilise
+`-PsanctuaryBloom130ClientTests=true` à la place de la propriété PixelShadows.
+Log complet : `build/shader130-client-full.log` ; captures sous
+`mods/sanctuary/build/run/clientGameTest/screenshots/`.
+
+`./gradlew check build assemblePack assembleTestPack -x :sanctuary:runGameTest`
+réussit en **2 min 24 s**, 126 tâches. Le serveur GameTest dédié reste exclu
+conformément au refus antérieur de son EULA. La comparaison au binaire beta.129
+trouve **24 entrées de production** modifiées, toutes limitées au shader et à
+ses interfaces. Gameplay et textures des gemmes inchangés ; aucun test,
+monde ou modèle GLB embarqué. Les sources archivées correspondent aux sources
+Java, les packs normal/Test embarquent le même JAR et le template contient
+exactement les ressources prévues.
