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. AddSigner accepts SignerInfoConfig with ExtraSignedAttributes and preserves custom signed attributes in DER output
  2. UnmarshalSignedAttribute decodes custom signed attributes added via SignerInfoConfig from parsed PKCS7
  3. UnmarshalSignedAttribute returns error when requested attribute is not present in SignerInfo
  4. Verify validates SignedData signature containing ExtraSignedAttributes configured through SignerInfoConfig
  5. AddSignerChain accepts SignerInfoConfig and includes parent certificate chain alongside custom signed attributes
  6. SignWithoutAttr accepts SignerInfoConfig with ExtraUnsignedAttributes to sign payload without authenticated attributes
