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. assert httpx2.__version__ is 2.10.0 and exports core client and transport interfaces
  2. assert Client with MockTransport dispatches requests, parses JSON, and passes custom headers offline
  3. assert response.raise_for_status() raises HTTPStatusError inheriting from HTTPError on 4xx status codes
  4. assert Headers and QueryParams provide case-insensitive access and URL-encoded query formatting
  5. assert ServerSentEvent parses event, data, id, and retry properties
  6. assert alias_httpx() aliases httpx and httpcore module imports process-wide to httpx2 and httpcore2
