This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured. How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. assert zh-CN, zh-HK, and zh-TW parse abbreviated months '10月', '11月', '12月' to month indices 9, 10, 11
  2. assert zh-CN parses wide months '十月', '十一月', '十二月' to month indices 9, 10, 11
  3. assert full Chinese localized date strings parse correct year, month, and day components
  4. assert Portuguese (pt) locale defaults weekStartsOn to Sunday (0) and startOfWeek computes Sunday
