+# 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.
+
+Commande : `./gradlew :sanctuary:runClientGameTest -PsanctuaryClientTests=true

+-PsanctuaryQuickTests=true`. Log `build/shader129-client.log`, captures sous
+`mods/sanctuary/build/run/clientGameTest/screenshots/`.
+
+`./gradlew check build assemblePack assembleTestPack -x :sanctuary:runGameTest`
+réussit en **2 min 17 s**, 126 tâches. Une dernière passe d’assemblage intègre
+la simplification du libellé de portée (2 min 18 s). Les archives sont vérifiées :
+**17 entrées de production** diffèrent de beta.128, limitées au shader et à ses
+interfaces. Même JAR dans normal/Test, sources archivées conformes, ressources
+du template exactes, assets des gemmes inchangés. Aucun monde ni test embarqué.
+Le serveur GameTest dédié
+reste exclu conformément au refus antérieur de son EULA. Aucun monde personnel
+utilisé pour les essais, aucun résultat Windows/Vulkan revendiqué.
+
+
+Archives vérifiées dans `build/` et recopiées dans le dossier de livraison
+habituel `sanctuary-beta/build/` :
