A cleanroom reimplementation of the par2 error-correction algorithm, library and cli in Zig, based only on publicly-available specs (NOT its source code), and with a more permissive license, a C ABI wrapper, and a LuaJIT FFI example. Full test coverage. NOTE: gpt-5.2-codex and Claude Opus 4.5 AI assisted in parts.
