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.

Contract
- assert attrs.validators.disabled() context manager is nestable and preserves disabled state across nested context exits
- assert validator failures raise ValueError outside disabled context
- assert field_transformer receives pre-resolved alias names and alias_is_default booleans on Attribute objects
- assert attrs.fields accepts instance objects directly and matches class field definitions
- assert frozen classes accept on_setattr=attrs.setters.NO_OP without error
