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. matchPropertyValue resolves General_Category aliases and short names to canonical ECMAScript property values
  2. matchPropertyValue resolves Script aliases and short codes to canonical script names
  3. matchPropertyValue resolves Script_Extensions aliases to canonical script extension names
  4. matchPropertyValue throws descriptive Error on unknown property
  5. matchPropertyValue throws descriptive Error on invalid or unknown value for property
  6. resolvePropertyValues resolves multiple aliases to canonical values in sequence
  7. tryResolvePropertyValue safely returns canonical value or null without throwing
