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. define a model and validate a correct payload with model_validate
  2. assert the v1 helpers still exist but warn, so a silent upgrade is not a completed migration
  3. assert an invalid payload raises ValidationError with a typed error list
  4. assert model_dump returns plain data
