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. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. TBSCertificate.Sign signs CA certificate details with an Ed25519 private key
  2. Certificate.MarshalPEM exports a signed certificate to PEM format
  3. NewCAPoolFromPEM initializes a CA pool from PEM certificate bytes
  4. TBSCertificate.Sign signs host certificate details using CA certificate and private key
  5. Certificate.VerifyPrivateKey verifies the private key corresponds to the certificate public key
  6. UnmarshalCertificateFromPEM parses a PEM encoded Nebula certificate
  7. CAPool.VerifyCertificate validates a certificate against a trusted CA pool
  8. Certificate.Expired returns true when evaluated outside validity dates
  9. CAPool.BlocklistFingerprint causes VerifyCertificate to reject blocklisted certificates
