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。

契约
- assert TestClient targets http://testserver, so the contract runs with network off and no DNS sockets
- assert jsonable_encoder([item], exclude_defaults=True) excludes default fields from items in top-level lists
- assert jsonable_encoder({'item': item}, exclude_defaults=True) propagates exclude_defaults into dict values instead of leaking default fields
- assert jsonable_encoder({'items': [item]}, exclude_defaults=True) propagates exclude_defaults through dicts containing lists
- assert jsonable_encoder({'data': {'items': [item]}}, exclude_defaults=True) propagates exclude_defaults through deeply nested dicts
- assert jsonable_encoder preserves default fields when exclude_defaults is False or omitted
- assert jsonable_encoder preserves non-default overridden fields when exclude_defaults is True
- assert exclude_defaults=True strips fields explicitly assigned their default value whereas exclude_unset=True retains them
- assert jsonable_encoder excludes defaults from nested Pydantic container models inside dictionaries
- assert jsonable_encoder({'data': null_model}, exclude_none=True) excludes None fields consistently
- assert FastAPI route responses returning dicts with exclude_defaults=True omit default fields over the wire
