// TensorZero integration tests are not feasible in this crate because it lacks
// access to `awaken-ext-observability`. The observability pipeline is fully
// tested via InMemorySink in:
// crates/awaken/tests/observability_e2e.rs (agent-loop level)
// crates/awaken-ext-observability/tests/ (unit + integration)
//
// A live TensorZero e2e test would require the DEEPSEEK_API_KEY environment
// variable and a running TensorZero gateway. That is covered by manual
// validation rather than CI.
