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. Certificate.Empty returns true for zero-value struct and false when Certificate bytes are populated
  2. Certificate.HasTag checks for presence of arbitrary tags in the Tags slice
  3. Certificate.Lifetime calculates the total validity duration from Leaf NotBefore and NotAfter
  4. Certificate.Expired returns true when current time is after leaf expiration and false otherwise
  5. Certificate.NeedsRenewal evaluates whether a certificate is due for renewal under Config renewal window
  6. DefaultCertificateSelector selects the first non-expired supported certificate and returns error on empty choices
