+# LIGHT-139 — Lumières colorées
+
+Socle beta.138 + vérification Vulkan `9d84a02`, Minecraft 26.3 / Java 25.
+Branche `codex/colored-lights-beta139`, livraison beta.139.
+
+## Contrat
+
+Option locale « Lumières colorées » avec intensité. Les vrais blocs émetteurs
+teintent discrètement leurs environs, y compris hors champ. Torches/lanternes,
+lave et feu chauds ; sources des âmes bleues ; redstone active rouge ;
+froglights par variante ; sources Sanctuary selon leur texture/matière.
+Les blocs éteints n'émettent pas. Le bloom et les inclusions émissives des
+minerais restent indépendants ; aucune lumière de gameplay n'est ajoutée.
+
+Propagation RGB dans un volume local de blocs chargés, obstacles et formes
+natives, construction répartie entre les images, cache des couleurs de
+matériaux. Aucun chargement forcé de chunk, accès aux mondes personnels,
+changement de sauvegarde, réseau ou règles serveur.
+
+## Réalisation
+
+Dans les options du shader : « Lumières colorées », désactivées initialement,
+et une intensité de 0 à 100 %, réglée à 35 %. Zéro ou OFF libère les ressources.
+Les préférences existantes sont conservées. Libellés et aides FR/EN.
+
+Les familles vanilla demandées ont une palette dédiée. Les autres émetteurs,
+y compris ceux de Sanctuary, utilisent la couleur des pixels lumineux de leurs
+textures de modèle, calculée puis mise en cache. Ce repli suit les packs de
+ressources ; les palettes dédiées vanilla restent constantes. Une texture
+illisible ou sans pixels exploitables utilise du blanc. Les blocs purement
+émissifs du bloom, sans émission lumineuse native, ne deviennent pas des lampes.
+
+Le champ couvre un cube de 64 blocs de côté autour de la caméra. Une marge de
+14 blocs réserve la propagation aux sources présentes dans le volume ; le rendu
+s'atténue progressivement sur 4 blocs à sa périphérie. C'est donc un effet de
+proximité, pas une illumination de tous les chunks visibles. Les formes et
+l'opacité natives règlent le passage de la lumière. Les canaux utilisent des
+maxima indépendants, sans addition illimitée des sources superposées.
+
+Le calcul CPU est réparti avec un budget visé de 2 ms par image, plus les
+allocations et chargements ponctuels de matériaux ; aucun chiffre de FPS n'est
+garanti. Un monde immobile réutilise son champ. Les changements rapides et les
+déplacements peuvent présenter un bref retard, le temps de publier un champ
+complet. Aucun chargement forcé de chunk. Une texture 512 × 512 contient le champ.
+La passe GPU teinte les surfaces visibles, atténue l'effet au soleil et dans le
+brouillard, puis laisse agir le SSGI et le bloom. Les sources tenues, entités,
+particules et le rendu sous l'eau/lave ne sont pas couverts par cette option.
+
+## Vérifications
+
+Essais client natifs réussis dans des mondes neufs (graine 122) sur Apple M1 :
+
+- OpenGL 4.1 Metal : **1 min 46 s**, `build/colored139-opengl.log`.
+- Vulkan / MoltenVK 1.4.2, profondeur 0–1 et transparence améliorée :
+  **1 min 30 s**, `build/colored139-vulkan.log`.
+
+Les deux journaux contiennent `COLORED139_PASS` et le backend réellement actif.
+Torche et torche des âmes hors champ, trois froglights, pierre lumineuse dont
+la couleur vient de sa texture, intensité 35/100, cache statique, déplacement
+et retour de caméra, mur fermé puis ouvert, lampe redstone allumée puis éteinte,
+retrait de source, rechargement des ressources et OFF/zéro vérifiés.
+Les préférences persistantes et les libellés FR/EN sont contrôlés ; une dernière
+capture active conjointement PBR, SSGI, bloom, ombres, highlights et rayons.
+
+Les sommes d'écart entre OFF et 35 % sont presque identiques entre backends :
+torche 2 025 577 / 2 025 576 ; âmes 964 200 / 964 201. Il s'agit de mesures
+sur les pixels de cette scène, pas d'un indice de performance.
+Comparatif autonome : `build/Shader-beta.139-comparaison.html`.
+Pas de validation du pilote Vulkan Windows de l'utilisateur revendiquée.
+Le test fige uniquement le scintillement vanilla des torches afin de comparer
+les images ; cette sonde est exclue du JAR distribué. Aucun monde personnel ouvert.
+
+## Diagnostic des essais
+
+La première comparaison de stabilité détectait le scintillement natif de la
+lightmap des torches, même avec un champ coloré inchangé. La sonde de test
+stabilise ce seul facteur ; aucune désactivation de scintillement en production.
+La pièce d'essai est désormais construite après le chargement de ses chunks,
+et l'absence de lumière du ciel est vérifiée avant les captures.
+
+## Construction et archives
+
+`./gradlew check build assemblePack assembleTestPack -x :sanctuary:runGameTest`
+réussit en **2 min 22 s**, 126 tâches. Le serveur GameTest dédié reste exclu
+conformément au refus EULA antérieur. Log : `build/shader139-build.log`.
+La comparaison à beta.138 trouve **13 entrées de production** modifiées,
+limitées au shader, à son menu et aux aides FR/EN. Les sondes de test sont
+absentes du JAR distribué. Sources, archives normale/Test et template complets
+vérifiés ; textures des gemmes et clé de Steve conservées à l'identique.
+Reçu local : `build/shader139-artifact.json`.
+
+JAR SHA-256 : `7b958f6576adbabb2b1af589b866cb52b1a65600ea2fa505b05dd283f8d595df`.
