description: 'A single guardrail violation.
Attribution fields (``provider``, ``stage``, ``step``) identify which
pipeline stage produced the violation so callers running multi-provider
pipelines can tell regex matches from llama-guard classifications.
``reason`` is an optional human-readable explanation. Regex matches do
not populate it (the category is sufficient); ``provider_error`` and
richer providers may set it to surface why a step failed or matched.'
