Git PR 工作流
The real friction is usually not library usage. It is validation, time allocation, and task framing.
难点不只是实现一个几何功能，而是在特殊退化情形下同时保证鲁棒性、精度和性能，并按要求提交可运行代码、测试与设计材料。多数题目还以 ACIS 的结果或耗时作为对照，且初赛代码须以 PR 方式提交到仓库。
This guide is the best pre-read if you want a cleaner start instead of trial-and-error.
