# OTEL trace smoke

```yaml qa-scenario
id: otel-trace-smoke
title: OTEL trace smoke
surface: telemetry
coverage:
  primary:
    - telemetry.otel
  secondary:
    - harness.qa-lab
objective: Verify a QA-lab gateway run emits bounded OpenTelemetry traces, metrics, and logs through the diagnostics-otel plugin.
successCriteria:
  - The diagnostics-otel plugin starts with trace, metric, and log export enabled.
  - A minimal QA-channel agent turn completes.
  - The trace includes the selected agent harness lifecycle span.
  - The run emits low-cardinality OpenTelemetry signals without content or raw diagnostic identifiers.
plugins:
  - diagnostics-otel
