兩項目評估報告
- EvalRun: #140（suite #78
auto-e875a090-r1-053958866）
- Target: #2 production-canary
- Cases: 28（N=1, attempts=28/28）
- Generated: 2026-05-16T13:29:22+08:00
本報告含兩個獨立評估項目。項目一 評估 bot 進入「知識與產品查詢」fallback
後的撈取 + 回答能力；項目二 評估 bot 跨全 enabled scenarios 的 routing →
tool → answer 三段 funnel 健康度。
項目一: 知識庫精準度
評估範圍 (prerequisite: 進對 scenario)
- 進對 scenario 的 attempts: 10 / 28 (35.7%)
- 只對這些 attempts 算 retrieval + answer
- 沒進對 scenario 的 attempts → 排除（routing 失敗不該污染 KB 訊號）
Per-scenario 評估
| Scenario |

| 知識與產品查詢 |
10 / 10 |
❌ 20.5% |
✅ 91.7% |
待修方向（worst-3）
- 知識與產品查詢 × retrieval_relevance = 20.5% — 撈到的 KB chunks 不夠相關 — KB content gap，跟 Neptune team 提 enrichment
- 知識與產品查詢 × answer_correctness = 91.7% — 回答內容有問題 — 細看 hallucination_rate vs answer_quality 哪邊低
