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 unique constraint violation raises sqlalchemy.exc.IntegrityError with statement and params attributes
- assert NOT NULL constraint violation raises sqlalchemy.exc.IntegrityError
- assert foreign key constraint violation raises sqlalchemy.exc.IntegrityError when foreign keys are enabled
- assert CHECK constraint violation raises sqlalchemy.exc.IntegrityError
- assert ORM session commit with duplicate unique field raises sqlalchemy.exc.IntegrityError and allows session rollback
- assert IntegrityError is a subclass of DatabaseError and SQLAlchemyError and wraps underlying DBAPI exception in orig attribute
