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. Policy::none returns the original 302 response without treating the redirect as an error
  2. Policy::limited(0) rejects the first 302 response with an error for which is_redirect returns true
  3. On the first redirect, RedirectAttempt::previous contains exactly the initial request URL
  4. A custom policy can follow the redirect and receive the final 200 response while observing the initial URL in previous
