DPO pair generation summary
---------------------------
Date: Sat May  9 11:32:12 PDT 2026
Source: data/quality_dev.json (n=20 items, 40 debate tasks)
Debater: openai:gpt-4o-mini
Judge:   anthropic:claude-haiku-4-5  (offloads rubric scoring from OpenAI to avoid TPM saturation)
Samples per task: 3 (so 120 rollouts total)
Filter: cleanliness >= 0.6, gap >= 0.1
Pairs produced: 38
Pairs file (gitignored): dpo_pairs_pol.jsonl

Notes:
  - Wall clock: ~22 minutes
  - Tier 1 OpenAI quota active (rate-limit retries fired ~6 times during the run, all caught by tenacity layer)
  - Hybrid provider config keeps gpt-4o-mini debater outputs (the model we'll fine-tune) while routing the
    larger 30-call rubric scoring burst to Anthropic (different TPM bucket).
  - Replaces an earlier 31-pair haiku-only run from before Tier 1 activation.
