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. urllib3.util.parse_url parses URL strings into structured Url objects with scheme, host, port, path, query, and fragment
  2. urllib3.util.Url constructs and formats normalized URL strings and relative request URIs from individual components
  3. urllib3.util.make_headers generates standard HTTP request headers for basic authentication, custom user agent, accept encoding, and keep-alive
