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. pytest.approx performs tolerant float comparisons for scalar, sequence, and dictionary structures with custom abs and rel tolerances
  2. pytest.approx supports nan comparison when nan_ok is explicitly enabled
  3. pytest.raises verifies expected exception types, matches error messages with regex, and yields ExceptionInfo
  4. pytest.raises accepts multiple expected exceptions as a tuple and fails when no exception is raised
  5. pytest.MonkeyPatch context manager safely modifies environment variables and restores them on exit
  6. pytest.main executes test sessions programmatically and returns ExitCode enum values
