Calculator 2 - Foundations

Foundations Calculator — Minecraft 1.21.1 — 0.1.0alpha.R2

Alpha prerelease. Built for this exact Minecraft/NeoForge target. Includes recipe allocation and lane-cache improvements, research packet batching, idle transfer fast paths, staggered nutrition scans and fewer scan lookups. R2 further reduces recipe-allocation objects using a flat graph and direct count loops, preserving slot order, recipe matching, timings, costs and scan schedules.

Native unit tests: 36. Runtime evidence is attached in release_checks.json. World-upgrade, broader client gameplay, multiplayer/protection and full-world performance acceptance remain incomplete. This is an experimental playable build. Use a backed-up or new test world. Requires Java 21.
