5. STATUTORY INTEROPERABILITY & CLEANROOM SPECIFICATION NOTICE
================================================================================

Pryzma is an independent compatibility engine designed to restore visual resource pack
and shaderpack functionality in modern Minecraft runtimes.

All format parsers, runtime adapters, and specification handlers for legacy resource pack
features (including `.properties` files, CTM tile connection rules, CIT item matchers,
and CEM skeletal models historically popularized by OptiFine and MCPatcher) are independent
cleanroom implementations developed solely for technical interoperability. Pryzma contains
no proprietary source code or binaries from OptiFine or MCPatcher.

Interoperability and technical adaptation are established and protected under:
