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. propertyAliases is an instance of Map exported by unicode-property-aliases-ecmascript
  2. propertyAliases.get maps property alias scx to canonical name Script_Extensions
  3. propertyAliases.get maps property alias gc to canonical name General_Category
  4. propertyAliases.get maps property aliases WSpace and space to canonical name White_Space
  5. propertyAliases.get returns undefined for unmapped or non-existent property aliases
  6. propertyAliases.has accurately reports existence of property aliases
  7. propertyAliases contains exactly 54 property alias entries
