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 schema type for an Ecto.Enum is a 2-element tuple {:parameterized, {Ecto.Enum, info}} rather than a 3-element tuple, Ecto.Type.parameterized? identifies it, and Ecto.Type.type returns the underlying primitive storage type
- assert casting an Ecto.Enum with mapped values accepts atom keys, string names, and raw mapped integers, while rejecting stringified integers with inclusion metadata
- assert Ecto.Enum reflections distinguish between Elixir value atoms, database dump values, and key-value mappings
- assert Ecto.Type.cast! returns normalized scalar values and raises Ecto.CastError on failure, while invalid composite arrays collapse to :error and changesets omit the failing element index
