Judge ONE seed-candidate match for the seed-generation Elo tournament. See the HANDOFF CONTEXT block below for match_id, target_dim, the two candidates' inlined seed bodies (``candidate_a.body`` / ``candidate_b.body``), and per-candidate pilot dim_means. You are voter openai.openai-codex ('gpt-5.5'). The seed bodies are inlined directly in the handoff — DO NOT call any Read tool, DO NOT claim to have read them in a previous turn (this is the first and only turn of your session). Weigh the inl...
