| Claim | 当前状态 | 证据文档 | 关键缺口 |
| --- | --- | --- | --- |
| C1. Harness 将 raw knob search 转成 mechanism-guided intervention search，提升固定预算优化效果 | 已有强信号 | [Qwen27B 2x2](harness-ablation/qwen27b-tight-2x2-model-ablation-20260623.md), [Qwen30B SLO robustness](harness-ablation/qwen30b-slo-robustness-20260624.md) | 补 Qwen235B decode 2x2 aggregate；补 mechanism ablation |
| C2. 收益来自 harness-defined substrate，不依赖某个强 LLM | 部分已有 | [Qwen27B 2x2](harness-ablation/qwen27b-tight-2x2-model-ablation-20260623.md) | 做 `BO/heuristic + harness` vs `BO/heuristic + raw knobs` |
| C1. Harness 将 raw knob search 转成 mechanism-guided intervention search，提升固定预算优化效果 | 已有强信号 | [No-LLM harness mechanism](harness-ablation/no-llm-harness-mechanism-20260625.md), [Qwen27B 2x2](harness-ablation/qwen27b-tight-2x2-model-ablation-20260623.md), [Qwen30B SLO robustness](harness-ablation/qwen30b-slo-robustness-20260624.md) | 补 Qwen235B decode 2x2 aggregate；补 mechanism ablation |
| C2. 收益来自 harness-defined substrate，不依赖某个强 LLM | Qwen30B no-LLM 已完整闭环；Qwen27B 弱/强模型已有 | [No-LLM harness mechanism](harness-ablation/no-llm-harness-mechanism-20260625.md), [Qwen27B 2x2](harness-ablation/qwen27b-tight-2x2-model-ablation-20260623.md) | 做 `BO/heuristic + harness` vs `BO/heuristic + raw knobs` |
| C3. Weak planner + harness 可以匹配或超过 strong LLM naive | Qwen27B 已支持；Qwen235B 正在补 | [Qwen27B 2x2](harness-ablation/qwen27b-tight-2x2-model-ablation-20260623.md), [Qwen235B prefill progress](harness-ablation/qwen235b-prefill-2x2-progress-20260623.md) | 完成 Qwen235B decode 2x2；更新 prefill final doc |
| C4. Attribution 和 intervention grammar 有机制贡献，不只是 prompt 信息更多 | 设计已有，严格证据不足 | [AITuner summary](aituner-harness-summary.md) | 做 shuffled attribution / no attribution / no grammar / no topology-first / no validator ablation |
| C4. Attribution 和 intervention grammar 有机制贡献，不只是 prompt 信息更多 | 设计和 no-LLM case 已整理；严格 ablation 不足 | [No-LLM harness mechanism](harness-ablation/no-llm-harness-mechanism-20260625.md), [AITuner summary](aituner-harness-summary.md) | 做 shuffled attribution / no attribution / no grammar / no topology-first / no validator ablation |
| C5. AITuner 找到 near-optimal region，而不是只找到一个可行 config | Qwen30B 有解释性信号 | [Qwen30B SLO robustness](harness-ablation/qwen30b-slo-robustness-20260624.md) | 选 1-2 个 case 做局部 grid 或专家配置对照 |
| C6. AITuner 能随 SLO tightness 移动到合适 frontier | Qwen30B 已完成 | [Qwen30B SLO robustness](harness-ablation/qwen30b-slo-robustness-20260624.md) | 再选一个非同质 case 做 SLO sweep；同时画 SLO tightness -> frontier/regime transition |
| C7. Engine adapter 让 intervention grammar 可迁移到其他 serving engine | 设计上可行，暂不作为主实验 claim | `EngineLaunchSpec` / launch recipe / tunable schema | vLLM 主线完成后，再做 SGLang adapter 和一个低成本验证 case |
