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
- jwt.NewWithClaims creates and signs a valid JWT token with HS256 HMAC-SHA256 method
- jwt.ParseWithClaims verifies token signature and decodes custom claims matching the original payload
- jwt.Parse rejects expired tokens and returns jwt.ErrTokenExpired
- jwt.NewNumericDate correctly sets IssuedAt and ExpiresAt timestamps for time-based claim validation
- jwt.Parse rejects tokens with invalid signature returning jwt.ErrSignatureInvalid
