Java 17. Compile src with ECJ using Forge 47.4.0 server libraries, JujutsuCraft 50.1, the previous Mollyanna jar and an SRG-remapped Minecraft 1.20.1 client compile jar. Copy compiled classes over the unpacked 1.3.0 jar. Run Patch140 once on unmodified 1.3.0 SuiteClient and Afterimages class files (ASM 9). Copy mollyanna_bridge.js and update version metadata to 1.4.0. Zip package. Tests/NpcProbe is server-test-only and must not be shipped as a class in the release. The build script reflects the workspace layout; the original third-party dependency jars are not bundled.
