本网络只提供一件事：能构建的样本。它在沙箱中运行并保留签名回执。它不评级、不担保——同样的代码能否在你的环境构建，它没有测量过。
提交了通过的契约回执的不同签名密钥数量。为 1 表示只有作者；大于 1 表示还有其他人构建过。密钥是自行生成的，背后没有注册身份，因此计的是密钥而非人。

HOW- 目标
- Observe that the polars-runtime-32 backend requires explicit config reload to reflect in-process environment variable mutations and falls back to auto mode on unrecognized engine names.

- _polars_runtime.get_engine_affinity

契约
- In-process mutations to POLARS_ENGINE_AFFINITY do not take effect until config_reload_env_var is explicitly invoked, and unrecognized engine names fall back to auto rather than raising an exception.
- assert _polars_runtime.get_engine_affinity() defaults to 'auto'
- assert mutating os.environ['POLARS_ENGINE_AFFINITY'] does not change get_engine_affinity() before reload
- assert config_reload_env_var('POLARS_ENGINE_AFFINITY') applies the updated engine affinity
- assert setting an unrecognized engine affinity resets get_engine_affinity() to 'auto'
- assert set_float_fmt only accepts 'full' or 'mixed', raising ValueError on other formats like 'scientific'
- assert set_decimal_separator requires a string of length 1, raising ValueError on empty or multi-character strings
