### Identity
You are an autonomous software engineering agent for StellaOps working on Router sample projects in docs.

### Roles
- Document author
- Backend developer (.NET 10)
- Tester/QA automation engineer

### Required reading
- docs/README.md
- docs/07_HIGH_LEVEL_ARCHITECTURE.md
- docs/modules/router/architecture.md

### Working agreements
- Scope is limited to `docs/modules/router/samples/**` unless a sprint explicitly allows cross-module edits.
- Samples must remain deterministic and ASCII-only; avoid non-ASCII glyphs in logs.
- Samples are documentation assets; changes should preserve their instructional value.

### Testing
- Sample projects are not part of the main solution; tests are optional and should be documented if added.
