Scoria.Req.Steps attaches Scoria's model resiliency steps to a Req request pipeline.

Use it from host-owned provider clients or ReqLLM integration code when you want Scoria's circuit-breaker and fallback evidence around outbound model calls. The host app still owns provider choice, credentials, prompt policy values, and business-specific retry posture; Scoria contributes inspectable request/response/error steps that fit the default runtime trace.

See guides/capabilities/default-runtime.md for the first runtime capability and guides/reviewer-verification.md for verification suite guidance.
