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. SnapshotFormat provides the JSON schema definition for Jest snapshot options
  2. validateSnapshotFormat validates compliant snapshot formatting options including indent and theme
  3. validateSnapshotFormat accepts empty configuration as all SnapshotFormat options are optional
  4. validateSnapshotFormat rejects invalid option types and negative indentation values
  5. validateSnapshotFormat rejects unrecognized top-level and nested theme properties
