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. endpoint.Chain wraps an Endpoint with multiple Middlewares in outer-to-inner execution order
  2. endpoint.Chain propagates context values, request arguments, and response values through the chain
  3. endpoint.Chain short-circuits execution when an outer Middleware intercepts without invoking next
