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. language.Parse and language.NewMatcher match requested BCP 47 language tags against supported preferences
  2. cases.Title, cases.Upper and cases.Lower apply language-aware case transformations
  3. norm.NFC, norm.NFD and norm.NFKD perform canonical and compatibility Unicode normalization
  4. width.Fold normalizes fullwidth characters to standard halfwidth ASCII forms
  5. transform.String applies chained transformers to transform text across normalizations and casing
