Yueyue Modern Technology 1.13.1 — Minecraft 26.3 / Fabric / Java 25

Changes since the previously published 1.12.42:

• Expanded sawmill products with wooden doors, standing signs, composters, ladders, bowls, crafting tables, chests, barrels and chiseled bookshelves. Final 1.13.1 yields use 8 planks per chest/barrel/chiseled bookshelf, 4 per crafting table/composter, and 2 planks per bamboo block; existing other products remain available.
• Raw uranium and raw uranium blocks now require the diamond or netherite furnace. Added stackable containers and heat-resistant containers, recipes and advancements, and a dedicated container slot in the blast furnace and both advanced furnaces. Existing saved slot IDs remain unchanged.
• Each oil-processing batch consumes one ordinary or heat-resistant container. The blast furnace produces gasoline; both advanced furnaces produce the five oil products together. Oil buckets return an empty bucket. Blocked output or missing containers do not consume inputs; already lit fuel continues burning normally.
• Heavy-water buckets require a heat-resistant container in the netherite furnace and return an empty bucket. Heavy water no longer regenerates source blocks; existing sources remain and normal water is unchanged. Container slots support side-hopper input and product/empty-bucket extraction from below.
• Updated tooltips, advancements and REI presentation. Reorganized the creative tab while preserving existing items and IDs; the advancement tab uses the thermonuclear-bomb icon. Nuclear-bomb tooltips state the 10-second fuse, 128-block spherical radius, liquid clearing, staged destruction and mushroom cloud; the thermonuclear radius remains 256 blocks.
• Renamed the alloy container to the heat-resistant container and gave it a distinct silver/tungsten model. Enriched uranium-235 blocks emit light level 12 with a smoother self-lit uranium surface. The 1.13.1 presentation update preserves recipes, container-consumption rules and explosion logic introduced in the preceding implementation.

Validation: previously completed isolated native server and full-pack client checks cover processing, containers, menu transfer, automation, saved slots, source-block behavior and presentation. The final 1.13.1 full-pack client passed 243 checks, and the corresponding public source independently rebuilds with identical JAR entries. This upload repackages that verified release; it does not claim a new gameplay test or access to a player's production world.

中文更新：自已发布的1.12.42起，补齐锯木机木制品；最终箱子/木桶/雕纹书架按8木板、工作台/堆肥桶按4木板、竹块按2木板折算。新增普通及耐热容器与三种炉的独立容器槽；炼油每批消耗1容器，重水桶需下界合金熔炉和耐热容器并返空桶；粗铀仅高级炉可炼，重水不再生成无限源。同步自动化、进度、REI及提示，保留已有ID和存档槽号。1.13.1整理创造栏、核弹说明、耐热容器模型及铀235发光外观。最终隔离整包客户端243项通过，公开源码独立重建条目一致；未打开正式玩家存档。

The attached complete-source ZIP is not a playable mod. Windows execution helpers are omitted for CurseForge compatibility; production source and resources are unchanged. Build with JDK 25 using the Java-based Gradle wrapper command in CF_SOURCE_BUILD.md. Third-party dependencies retain their own licenses and are obtained separately.
