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. resolveALPN negotiates and returns the selected ALPN protocol from a TLS server
  2. resolveALPN destroys the socket by default and resolves with alpnProtocol and timeout status
  3. resolveALPN with resolveSocket enabled returns the active TLSSocket alongside alpnProtocol
  4. resolveALPN supports custom connect functions for custom socket factory integration
  5. resolveALPN rejects when the socket connection encounters an error
  6. resolveALPN sets timeout to true when socket times out
