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

Contract
- pkcs7.NewSignedData creates signed data payload verifiable with Parse and Verify
- SignedData.Detach produces detached signature with empty content verifiable when original data is provided
- SignedData.AddSignerChain includes intermediate certificates in SignedData and verifies against a root cert pool
- SignedData with custom signed attributes embeds attributes unmarshable by PKCS7.UnmarshalSignedAttribute
- PKCS7.Verify fails when payload data is tampered or corrupted
