Sample
Modular routing with FastAPI APIRouter prefix nesting route dependencies response models and path precedence

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 APIRouter prefix concatenates with include_router prefix so child router routes are exposed under parent and app prefixes
- assert router-level dependencies execute before endpoint-level dependencies and block unauthorized requests with HTTPException
- assert nested routers inherit parent router dependencies and execute them in top-down hierarchical order
- assert static route registered before parameterized route matches exact path instead of capturing parameter
- assert route response_model on APIRouter filters dictionary output to declared Pydantic schema fields
- assert APIRouter status_code parameter sets HTTP status code on response
- assert app.dependency_overrides intercepts dependencies declared at the APIRouter level
- assert direct endpoint function call bypasses APIRouter dependency resolution and routing decorators
