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 Bidi.isRtlLanguage recognizes Kurdish Sorani ckb and ckb_IQ as RTL
  2. assert verifiedLocale resolves deprecated language codes like iw and in to modern supported equivalents he and id and vice-versa
  3. assert DateFormat.tryParseUtc parses timestamp strings strictly into UTC DateTime without local offset drift
  4. assert NumberFormat.compact formats negative values with negative sign prefix and respects explicit positive signs
  5. assert NumberFormat.tryParse returns null on non-numeric input instead of throwing FormatException
