Upstream MIT License copyright 2018-2024 Scott Sherman. The repository root LICENSE explicitly grants MIT; package.json contains a stale UNLICENSED package-publication field. Root license and GitHub API both identify MIT. Built with locked TypeScript 5.6.3 using npm ci --ignore-scripts, npm run build. 345 upstream specifications pass. flexagon-engine.js is the complete readable compiled original source, with only a missing source-map reference removed. No source engine changes. missions.js/app.js/style.css/index.html are original MIT interface and challenge code. Fixed regular hexaflexagon, no arbitrary scripts. Original rendering is a discrete state diagram, not a physical animation or collision simulation.
