O — OBJECTIVE
Waterson 的業務人員在回覆客戶信件時，不再只是報產品型號和價格，而是讓每一封回信都展現專業洞察 — 客戶收到信的第一反應是「這家公司真的懂我的問題」，而不是「又一封制式報價」。
G — GOAL
Bizbase AI Helper 從「產品配對報價工具」升級為「智能銷售顧問」— 每封自動產生的回信都包含三層價值：產品推薦 + 專業知識引用 + 即時運費報價，讓業務回信時間從 15 分鐘降到 2 分鐘，同時回信品質從「制式模板」提升到「Challenger + Peak-End 結構」。
Realistic Processing Time Breakdown (5-layer pipeline):
| Layer | Operation | Target Time |
|-------|-----------|-------------|
| 1 | Knowledge-index query (knowledge-index.json lookup) | <0.5s |
| 2 | Shipping calculation (3-formula module) | <0.5s |
| 3 | Marketing target judgment (decision tree) | <0.3s |
| 4 | Claude Opus rewrite (3-layer enrichment) | ~45s |
| 5 | Gemini Flash fact verification | ~15s |
| Total pipeline | | ~62s |
| +Buffer | Network latency + API retries | +58s |
| Wall-clock target | | ≤2 min |
Note: The "2 minute" target is achievable but requires all APIs responding within normal latency. If Opus or Flash experience >2x normal latency, total may exceed 2 min. In that case, show a progress indicator ("Generating smart reply…") and do not time out before 3 min.

Input: Upgrade task request + phase completion signals from Agents 1–4
