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
- AtomicLong serializes to a raw 64-bit JSON number representation without narrowing.
- A numeric string above Integer.MAX_VALUE deserializes to AtomicLong without 32-bit truncation.
- A floating-point token above Integer.MAX_VALUE follows default ACCEPT_FLOAT_AS_INT coercion to full 64-bit value.
- A negative numeric string below Integer.MIN_VALUE preserves its 64-bit value.
- A large integral token near Long.MAX_VALUE deserializes accurately.
- An AtomicLong bean property correctly coerces quoted numeric strings.
- Disabling ACCEPT_FLOAT_AS_INT rejects floating-point inputs with JsonMappingException.
- Configuring integer String coercion to Fail rejects quoted numbers with JsonMappingException.
