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.

Contract
- certifi.where returns an absolute path to an existing and readable CA bundle PEM file
- certifi.contents returns a non-empty UTF-8 string containing PEM formatted root certificates
- ssl.create_default_context accepts cadata from certifi.contents and successfully loads trusted CA certificates
