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.

Case
HOW- Goal
- Demonstrate how Equatable.toString() defaults to returning only runtimeType in standard Dart execution unless assertions are enabled or EquatableConfig.stringify is explicitly set.

Contract
- Calling toString() on an Equatable instance without explicit stringify overrides returns only the runtimeType string 'DefaultItem' rather than 'DefaultItem(a, 42)' when assertions are not enabled.
- Explicitly setting EquatableConfig.stringify = true causes toString() to include properties regardless of assertion mode.
- Overriding get stringify => true on an Equatable class includes properties even when EquatableConfig.stringify is false.
