Support triage + summaries
High-volume classification, summarization, and structured response drafts.
Candidate route
Decision
Route routine traffic. Keep Sonnet for low-confidence cases.
Evidence gate. Pass the frozen support-summary eval at the approved factuality and format threshold.
Fallback. Send low-confidence or policy-sensitive cases to Claude Sonnet 5.
Rollback. Restore the prior route with one policy change if quality or latency falls below threshold.
