</ResponseField>

<ResponseField name="learned" type="StrategyStat[]" required>
  Per-pair performance rows, one for each observed (query-class, strategy).

  <Expandable title="StrategyStat">
    <ResponseField name="mean_confidence" type="number (float)" required />

    <ResponseField name="mean_latency_ms" type="integer (int64)" required />

    <ResponseField name="query_class" type="string" required />

    <ResponseField name="samples" type="integer (int64)" required />

    <ResponseField name="strategy" type="string" required />

    <ResponseField name="success_rate" type="number (float)" required />

    <ResponseField name="trusted" type="boolean" required>
      True once the pair has enough samples for the bandit to exploit it.
    </ResponseField>
  </Expandable>

<ResponseField name="learned_pairs" type="integer" required>
  Number of learned (query-class, strategy) pairs in `learned`.
</ResponseField>
