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

+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
+utilise la couleur et la profondeur visibles pour des rebonds diffus ; voir
+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
+initiale, le SSGI avec ombres/highlight/bloom/émissifs actifs, ainsi que
+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.
