+# 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

+puis rendu PBR et combinaison des effets. Log : `build/shader135-defaults-client.log`.
+`./gradlew check build assemblePack assembleTestPack -x :sanctuary:runGameTest`

+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

+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.

+# SHADER-137 — Rayons solaires volumétriques
+
+Demande validée : faisceaux légers découpés par les blocs, carte d'ombres partagée,
+feuillage perméable, rendu natif préservé, option et intensité indépendantes du bloom.
+Socle beta.136, branche `codex/sunshafts-beta137`, Minecraft 26.3 / Java 25.
+Aucun changement de monde ni de gameplay.
+
+## Contrat
+
+Soleil uniquement ; activé initialement à 35 %, intensité 0–100.
+Intégration de 16 segments par pixel à un quart de chaque dimension.
+Reconstruction guidée par la profondeur, sans historique ni bruit animé.
+Réutilisation du masque de feuillage déjà stable dans les ombres.
+La carte solaire peut fonctionner sans afficher les ombres sur les surfaces.
+Portée bornée à 64 blocs et à la moitié de la portée des ombres.
+Atténuation aux limites de la carte, à l'horizon et avec la météo.
+
+## Rendu et coût borné
+
+Deux passes : intégration dans une cible RGBA16F de largeur et hauteur divisées
+par quatre, puis reconstruction guidée par la profondeur. Seize segments
+quadratiques privilégient les premiers mètres ; quatre lectures fixes de la
+carte d'ombres par segment adoucissent seulement la lumière dans l'air.
+La dernière portion du rayon rétrécit continûment à l'approche d'une surface.
+La lumière utilise une teinte solaire chaude mélangée au brouillard natif.
+
+La carte d'ombres et ses maillages sont partagés, y compris les trous de
+transmission déterministes des feuilles. Aucune copie d'image plein écran,
+aucune duplication du terrain, aucune lecture GPU côté CPU ni accumulation
+entre images dans le rendu de production. OFF/zéro libèrent le volume ; la
+carte d'ombres reste seulement si les ombres de surface sont activées.
+Le soleil sous l'horizon et la submersion suspendent les rayons.
+
+## Vérifications
+
+Scénario natif réussi en **1 min 41 s** sur macOS / Apple M1 / OpenGL : pièce
+entièrement fermée, toit ajouré OFF/35/100, feuilles puis ciel ouvert, déplacement
+de quatre blocs et retour, caméra proche d'un mur à 0,5 puis 0,125 bloc,
+soleil hors champ, nuit, OFF/zéro, carte d'ombres partagée, effet combiné,
+redimensionnement à 961 × 541 et rechargement des ressources. Préférences
+vierges/partielles/personnelles, bornage et libellés FR/EN également vérifiés.
+Log : `build/shader137-client-final.log`, marqueur `SUNSHAFT137_PASS`.
+Comparatif autonome : `build/Shader-beta.137-comparaison.html`.
+
+La première tentative s'est arrêtée sur une comparaison de gain brut entre
+feuillage et ciel ouvert. La composition dispose de moins de marge sur un mur
+déjà clair : le test compare maintenant la contribution normalisée sur les mêmes
+surfaces, et les feuilles du scénario sont persistantes. Aucun seuil du rendu
+n'a été assoupli pour faire passer ce contrôle.
+
+Les contrôles natifs existants du bloom, des vingt textures de minerais émissifs
+et du lens flare réussissent également en **1 min 32 s**, avec leurs seuils
+inchangés. Log : `build/shader137-regression.log`, marqueurs `EMISSIVE131_PASS`
+et `LENS_FLARE136_PASS`. Les autres effets sont explicitement isolés dans les
+scénarios qui nécessitent une image témoin sans rayons.
+
+## Limites
+
+Le volume utilise les formes présentes dans la carte d'ombres existante :
+il n'ajoute pas de projection d'ombre des entités ou des nuages. Le feuillage
+reste une approximation par transmission déterministe. Portée maximale de
+64 blocs, atténuée à son extrémité. Le faible nombre de segments et la résolution
+réduite peuvent lisser les ouvertures très fines. Aucun résultat Windows/Vulkan
+ni mesure de FPS revendiqués.
