Sample
Verify requests 2.34.2 HTTPAdapter connection pooling, retry policy integration with urllib3 Retry, and status-based retry exceptions without real network IO

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
- assert HTTPAdapter initializes with default pool size of 10 and a zero-retry urllib3 Retry instance
- assert custom urllib3.util.Retry configuration and pool sizes are preserved and configured on the pool manager
- assert HTTPAdapter.get_connection provisions HTTPConnectionPool and HTTPSConnectionPool matching target scheme and reuses instances for the same host
- assert HTTPAdapter.build_response converts urllib3 HTTPResponse into requests.Response with CaseInsensitiveDict headers and attached request reference
- assert HTTPAdapter.request_url returns relative path_url for direct requests and full URL for HTTP proxy requests
- assert Session.mount gives custom HTTPAdapter prefix precedence over default adapters
- assert HTTPAdapter.send translates urllib3 MaxRetryError caused by ResponseError into requests.exceptions.RetryError
- assert RetryError inherits directly from RequestException and is not a subclass of ConnectionError
