Nearby Chest Crafting

Minecraft 1.20.1 backport: nearby-container scanning, double-chest deduplication, recipe-book autofill, server-authoritative withdrawal and safe item return on close/disconnect. Item identity includes enchantment/name NBT. Settings distinguish local appearance from server search range. Optional JEI integration reserves the nearby panel area instead of overlapping the recipe viewer.

Java 17; Fabric Loader 0.19.5 and Fabric API 0.92.12+1.20.1 tested. Requires matching 1.20.1/Fabric SeamlessLib 2.x. Optional Mod Menu 7.2.2; metadata correctly uses the 7.x range. Optional JEI 15.62.0.219 + MezzConfig 0.6.8 tested. No runtime Architectury API.

Passed clean build, 16 unit tests, 11 required Fabric GameTests, independent client and two-client native multiplayer with/without JEI, actual autofill/return/disconnect NBT conservation, GUI scales 2/3/4, resource reload and server restart. Software OpenGL/copied fixtures do not guarantee every GPU, pack or historical save. GitHub CI did not run due to billing lock. Back up worlds/configs; never downgrade 26.x saves.
