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
- z.string() and z.number() validate primitive values and reject invalid types
- z.object() validates structured objects and applies default values for missing optional fields
- z.discriminatedUnion() dispatches validation based on discriminator tag and validates matching member schema
- z.string().pipe() executes schema transformation pipelines and validates refined output
- z.coerce converts string representations into primitive numbers and booleans
- safeParse() returns structured error issues and field-level error mapping upon validation failure
