Scope

Targets develop/1.20.1, not 1.21. Version: 20.2.4.6.

Backports the newer Useless Mod feature tree (source snapshot 19d1cc0) to Minecraft 1.20.1 / Forge 47.3.10 / Java 17, with the Create 2 Mekanism: Sky Edition 2 integration profile.

• Forge-native NBT/component, payload, capability, menu and recipe bridges; native recipe adapters for the supported pack integrations.
• Preserve typed AEKey ingredients/bookmarks instead of exposing generic wrapped-stack placeholders; adapt Mekanism chemicals and AE2 15 / AdvancedAE crafting state.
• Fix AE crafting-list pagination and world-space selection outlines.
• Remove temporary dispatch/GUI/stress diagnostics and console prints. Keep actionable failures with bounded, per-template rate limiting, and keep recipe-catalog build summaries.
• Replace workstation-local Maven/JAR inputs with pinned public dependencies. Add CI and permanent recipe, bookmark, pagination, logging and bytecode regression checks.
• Remove migration/probe clients, local binary dependencies, generated reports and ad-hoc changelogs from the checkout. Preserve upstream copyright/license notices.

Compatibility boundaries

This is a pack-focused backport, not a claim that every 1.21 optional integration has been ported. Dormant integration sources and exclusions are listed in gradle/forge1201-pack-profile.json.

Extended Crafting compiles against publicly available official 6.0.10. The pack's unofficial tier-5 / 11x11 extension is supported through its native recipe contract and registry lookup; its version-specific tier contract has a dedicated test fixture. No pack dependencies, configs or worlds are replaced by this PR.

Validation

• Java 17: gradlew.bat clean build --offline --console=plain — passed after removing local migration artifacts.
• Final gradlew.bat build --offline --no-build-cache --console=plain — passed.
• 155 JUnit tests + 9 release-bytecode/outline checks, no failures or skips.
• No temporary/probe code or bundled dependency JARs added to the release.
• This cleanup revision has not had a new full in-pack interactive acceptance run; the validation above is automated build/regression coverage.
