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. extend dayjs with updateLocale, localizedFormat, and relativeTime plugins
  2. override a single format token like L in the de locale via updateLocale
  3. assert updated format L reflects the new custom pattern
  4. assert unmentioned format tokens like LT retain locale-specific 24-hour formatting
  5. override a single relativeTime token like s in the en locale via updateLocale
  6. assert unmentioned relativeTime tokens like hh and past remain intact and format correctly
