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. assert client.writer().write_all() buffers in memory without writing bytes to transport until write_tls() is called
  2. assert client.read_tls() pulls raw TLS records but reader().read() yields WouldBlock until process_new_packets() is called
  3. assert process_new_packets() parses TLS record headers and rejects invalid messages that read_tls() accepts
  4. assert ServerName::try_from() rejects hostnames with ports or schemes but parses IP addresses as ServerName::IpAddress
  5. assert RootCertStore::add_parsable_certificates() returns a (valid, ignored) tuple count instead of returning an Err
