  "verdict": "A == B (4/4 prompts 产出文件 byte-identical, md5 全匹配)",
  "headline": "Claude (sonnet-4) 与 DeepSeek (deepseek-chat) 对这 4 个 prompt 产出了字面意义上一字节不差的文件。对比在 latency 上仍有 ~2x 差距（Claude 慢），但生成内容趋同。",
  "caveats": [
    "A 端是 Claude Code CLI (`claude -p`) 非交互模式，不走 ACP 协议",
    "B 端是 dsh (`dsh --profile headless`) 直接 CLI，不走 ACP 协议",
    "两路都是 CLI spawn → stdout，协议层对称，但都不是真 ACP",
    "Round 2 才会引入真 ACP（A 端装 @agentclientprotocol/claude-agent-acp）",
    "prompts 模板相对死，模型无自由发挥空间 → 重写 prompt 才能区分模型"
