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
- In Europe/Dublin under tzdata 2026c, winter periods have dst? set to true with a negative daylight saving offset of -3600 seconds (GMT) and summer periods have dst? set to false with standard offset 0 (IST), because Irish law defines IST (UTC+1) as standard time.
- Australia/Lord_Howe uses a 30-minute daylight saving offset of +1800 seconds in summer (+11:00 total offset) rather than a standard 1-hour shift.
- Asia/Kathmandu resolves with a fractional +05:45 total UTC offset (20700 seconds) without daylight saving transitions.
- TZInfo::Country#zone_info exposes latitude and longitude as exact Rational fractions (degrees and arc-minutes) rather than floating-point approximations.
- Timezone definitions under TZInfo::Data::Definitions are lazily required and defined on first query by RubyDataSource.
