+# beta.157 — photo obligatoire et galerie de captures
+
+## Contrat de migration communautaire v2
+
+La génération, les chunks et les sauvegardes Minecraft ne changent pas.
+Seul le document communautaire évolue : champ `photo`, JPEG encodé en base64,
+48 Kio binaires maximum, dimensions de 1 × 1 à 960 × 540 pixels.
+Les captures originales ne sont jamais modifiées. Les copies destinées à la Gazette
+sont redimensionnées et réencodées, sans métadonnées, avant transmission.
+
+Les nouveaux articles exigent une photo valide. Les articles v1 restent lisibles ;
+leur prochaine modification exige une photo. Avis, intendance et réponses restent
+textuels. La modération ne nécessite pas d'ajouter une photo à un ancien article.
+La photo est enregistrée atomiquement avec le texte, auteur et révision ; pas de
+référence à un chemin local, d'URL distante ou de média orphelin persistant.
+
+Fichier : v1 est lu sans modification. À la première écriture réussie, une copie
+exacte `sanctuary-community.json.v1.bak` est créée sans écrasement, puis le document
+v2 est écrit atomiquement. Un backup différent bloque la migration. La limite de
+64 Mio du document reste appliquée, photos comprises. Un retour à beta.156 exige
+de restaurer la copie v1 et perd les changements communautaires postérieurs.
+Ne pas restaurer pendant que le serveur tourne.
+
+MariaDB : arrêter les écritures du site et du serveur, sauvegarder la base, exécuter
+explicitement `community/schema-v1-to-v2.sql` ou la migration Laravel équivalente,
+puis lancer les deux applications v2. Migration additive : colonne `photo` nullable,
+aucune suppression ni réécriture des articles existants. Le mod n'exécute aucune
+migration SQL au démarrage. Les applications v1 refusent le schéma v2. Pas de
+rollback automatique destructif ; restaurer la sauvegarde avec les deux logiciels
+v1 si nécessaire. Aucun changement n'est appliqué aux bases ou mondes personnels
+par la préparation de cette livraison.
+
+Réseau : canaux v1 conservés, action `photo` par fragments de 8 000 caractères,
+au plus 9 fragments et 65 536 caractères, accusés un par un. Une seule photo
+transitoire par joueur, liée à l'UUID de publication, expire après deux minutes ;
+limite globale de 128 transferts. Les listes ne transportent pas les photos ;
+seul le détail d'un article les contient. Le plafond des réponses
+passe à 262 144 caractères pour une photo et une discussion complète ; les
+clients et le serveur doivent être mis à jour ensemble vers beta.157. Les
+anciens clients ne peuvent plus créer d'article sans photo.
+
+Galerie : grille de 2 ou 3 colonnes selon la taille d'interface, molette et barre
+native, 24 captures par page parmi les 4 096 PNG les plus récents par nom, lecture
+en arrière-plan. Aperçu puis assignation explicite ; Annuler conserve le brouillon.
+Les captures illisibles restent visibles mais désactivées. Limites sources :
+32 Mio, 8 192 pixels par axe et 32 millions de pixels. Textures libérées à la
+fermeture. Le site accepte PNG/JPEG et nécessite PHP GD ; le mod propose les PNG
+du dossier `screenshots` de son instance.
+
+## Vérifications
+
+- Tests natifs Vulkan Minecraft 26.3 : galerie FR/EN aux échelles 2/3/4,
+  molette, pagination, aperçu, annulation avec brouillon conservé, bouton Publier
+  désactivé sans photo, envoi fragmenté, photo visible et relecture après
+  réouverture de l'adaptateur. Parcours réussi en fichier et MariaDB.
+- Tests métier : photo manquante/invalide, révision, auteur, conservation après
+  modification, reprise idempotente, redémarrage fichier/SQL, ancien article v1,
+  copie de migration exacte, fragments hors ordre/incomplets/expirés.
+- Site : 17 tests HTTP, 97 assertions réussies ; photo obligatoire, faux fichier,
+  dimensions refusées, réduction, lecture, isolement serveur, auteur, masquage,
+  anciennes publications et conservation après modification.
+- Échange réel Java/PHP sur une MariaDB isolée : création en jeu lue par le site,
+  modification et réponse Web relues en Java, article/photo du site décodés par
+  Java. Migration Laravel et alternative SQL testées sur bases de développement.
+- `./gradlew check build assemblePack` : 252 GameTests serveur terminés en
+  3,457 minutes, 229 réussis et les mêmes 23 échecs que la baseline beta.154/155
+  (liste comparée intégralement, aucun nouvel identifiant en échec). La commande
+  générale échoue donc après 6 min 59 s ; cette limite préexistante reste ouverte.
+- Régression native du menu pause : FR/EN, échelles 2/3/4, carte, défilements
+  indépendants, pagination, article et avis longs, réponse, options et reprise :
+  réussie avec les articles munis d'une photo.
+- Construction et assemblage séparés, sans relancer les 23 GameTests connus :
+  `check build assemblePack -x :sanctuary:runGameTest` réussit (avec le parcours
+  client natif du menu pause), 2 min 56 s.
+
+Les captures d'essai sont des mires générées dans une instance de développement,
+sans accès aux captures ou sauvegardes personnelles. Pas de déploiement sur le
+site public, serveur personnel, canal packwiz ou Prism. Les JAR beta.154–156
+restent présents ; JAR et MRpack beta.156 gardent leurs empreintes antérieures.
+
+
+Le site correspondant est sur `codex/community-photos`, commits `e3ae3eb` et
+`9626e95`, sans push ni publication. Logs de développement :
+`build/photos157-client-file.log`, `build/photos157-client-database.log`,
+`build/photos157-interop-*.log`, `build/photos157-check-build.log` et
