Rewrite the dataset card as a concise Desargues sample handoff, remove standalone sources and licensing sections, fix the download and task examples, and clarify environment delivery and validation. Align supporting documentation and package descriptions with the two-task subset; label full-release runtime reports as historical. Preserve task payloads and license files.
Include absolute profinite rigidity and algebraic integers from desargues-hf/annals-math-rl at 47c059fff6899b996f32aaaf12dc27a74a2cc7a3. Preserve README, documentation, licensing and selected mathematical files. Trim task indexes and all bundled challenge/source inventories to these two tasks.
