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. package manifest defines main, types, exports, and depends on @jest/expect at version 30.4.1
  2. importing @jest/globals outside the Jest test environment throws runtime guard error
  3. exports expect symbol declared as JestExpect type imported from @jest/expect
  4. declares test runner lifecycle globals test, it, describe, beforeAll, and afterAll
