feat(ai): Phase 22 OpenClaw + Nemotron 協作架構 (ADR-044)
統帥批准實作「仲裁-執行分工」架構:
- OpenClaw = 仲裁者 (Why + Risk Level)
- Nemotron = 執行者 (How + kubectl Command)

新增功能:
- config.py: ENABLE_NEMOTRON_COLLABORATION Feature Flag
- openclaw.py: generate_incident_proposal_with_tools()
- openclaw.py: _call_nemotron_tools() Nemotron 呼叫
- telegram_gateway.py: TelegramMessage Nemotron 欄位
- telegram_gateway.py: format_with_nemotron() 雙區塊格式
- decision_manager.py: 整合協作方法
- proposal_service.py: 整合協作方法

觸發條件:
- LOW 風險 → 僅 OpenClaw
- MEDIUM/HIGH/CRITICAL → OpenClaw + Nemotron 雙軌

首席架構師審查: 83/100 條件通過

# ADR-044: OpenClaw + Nemotron 協作架構
> **狀態**: ✅ **已批准**
> **決策日期**: 2026-03-31
> **批准日期**: 2026-03-31 18:30 (台北時區)
> **決策者**: 首席架構師 + 統帥
> **提案者**: Claude Code
> **相關**: ADR-036 Nemotron Tool Calling, Phase 18 自動修復
## 背景
AWOOOI 目前有兩個 AI 能力:
1. **OpenClaw** - 主要大腦,負責 Root Cause Analysis、風險評估、決策推理
2. **Nemotron** - Tool Calling 專家83.3% 精準度執行 K8s 操作
統帥需求:在同一個 Telegram 中同時看到兩者的分析結果。
## 問題陳述
如何讓兩個 AI 在 Telegram 中協作,而不會:
- 訊息混亂(誰說了什麼?)
- 責任不清(誰做的決策?)
- 無限迴圈(互相觸發)
- 增加過多延遲
## 決策
### 採用「仲裁-執行分工」架構
```
OpenClaw = 仲裁者 (Arbitrator) - 決定「為什麼」和「風險等級」
Nemotron = 執行者 (Executor) - 決定「怎麼做」和「具體指令」
```
### 職責分離
| 角色 | OpenClaw | Nemotron |
|------|----------|----------|
| **任務** | Root Cause Analysis | Tool Calling |
| **輸出** | 風險等級 + 責任團隊 + 原因推理 | kubectl 指令 + 參數驗證 |
| **模型** | Ollama/Gemini (RCA 任務) | Nemotron-mini (Tool 任務) |
| **信心度** | 0-100% (AI 分析品質) | 驗證狀態 (✅/❌) |
| **備援** | Expert System 規則 | Gemini Tool Calling |
### 流程設計
```
1. Incident 產生
2. OpenClaw.generate_incident_proposal()
→ 輸出: risk_level, reasoning, primary_responsibility
3. 判斷是否需要 Nemotron
├─ LOW 風險 → 跳過 Nemotron
└─ MEDIUM/HIGH/CRITICAL → 呼叫 Nemotron
4. NvidiaProvider.tool_call()
→ 輸出: tool_name, arguments, validation_status
5. 組合結果 → 推送 Telegram 卡片
6. 用戶簽核 → 執行
```
### 觸發條件
| 風險等級 | OpenClaw | Nemotron | 原因 |
|----------|----------|----------|------|
| LOW | ✅ | ❌ | 低風險操作不需要 Tool 驗證 |
| MEDIUM | ✅ | ✅ | 需要 Tool 驗證操作可行性 |
| HIGH | ✅ | ✅ | 高風險必須雙重驗證 |
| CRITICAL | ✅ | ✅ + HITL | 危險操作必須人工介入 |
## 實作規格
### 1. 擴展 TelegramMessage
```python
@dataclass
class TelegramMessage:
# 現有欄位...
# 新增 Nemotron 結果欄位
nemotron_enabled: bool = False
nemotron_tools: list[dict] | None = None # Tool Calling 結果
nemotron_validation: str = "" # "✅ 驗證通過" / "❌ 驗證失敗"
nemotron_latency_ms: float = 0.0
```
### 2. 擴展 generate_incident_proposal
```python
async def generate_incident_proposal_with_tools(
self,
incident_id: str,
severity: str,
signals: list[dict],
affected_services: list[str],
) -> tuple[dict | None, str, bool]:
"""
Phase 22: OpenClaw + Nemotron 協作
Returns:
(proposal_dict, provider, success)
proposal_dict 新增:
- nemotron_tools: Tool Calling 結果
- nemotron_validation: 驗證狀態
"""
# Step 1: OpenClaw 仲裁
proposal, provider, success = await self.generate_incident_proposal(
incident_id, severity, signals, affected_services
)
if not success:
return proposal, provider, success
# Step 2: 判斷是否需要 Nemotron
risk_level = proposal.get("risk_level", "low").lower()
if risk_level == "low":
proposal["nemotron_enabled"] = False
return proposal, provider, True
# Step 3: Nemotron Tool Calling
from src.services.nvidia_provider import get_nvidia_provider
nvidia = get_nvidia_provider()
tool_result = await nvidia.tool_call(
messages=[{
"role": "user",
"content": f"""
根據以下分析,生成對應的 kubectl 操作:
- Incident: {incident_id}
- 原因: {proposal.get('reasoning', '')}
- 目標資源: {proposal.get('target_resource', '')}
- 建議操作: {proposal.get('action', '')}
"""
}],
tools=K8S_OPERATION_TOOLS,
)
# Step 4: 驗證 Tool Calling 結果
validation = await self._validate_tool_calls(tool_result.tool_calls)
proposal["nemotron_enabled"] = True
proposal["nemotron_tools"] = [
{"tool": tc.tool_name, "args": tc.arguments, "valid": tc.valid}
for tc in tool_result.tool_calls
]
proposal["nemotron_validation"] = validation
proposal["nemotron_latency_ms"] = tool_result.latency_ms
return proposal, provider, True
```
### 3. Telegram 卡片格式
```python
def format_with_nemotron(self) -> str:
"""格式化含 Nemotron 結果的訊息"""
# OpenClaw 區塊
openclaw_block = f"""
🤖 <b>OpenClaw 仲裁</b>
├ 📊 信心: {self.confidence_emoji} {self.confidence_pct}%
├ 👥 責任: {self.primary_responsibility}
└ 💡 原因: {self.root_cause[:50]}
"""
# Nemotron 區塊 (如果啟用)
nemotron_block = ""
if self.nemotron_enabled and self.nemotron_tools:
tools_str = "\n".join([
f" {'' if t['valid'] else ''} {t['tool']}: {t['args'][:30]}"
for t in self.nemotron_tools[:3] # 最多顯示 3 個
])
nemotron_block = f"""
━━━━━━━━━━━━━━━━━━━
🔧 <b>Nemotron 執行方案</b>
{tools_str}
└ 驗證: {self.nemotron_validation}
"""
return f"{openclaw_block}{nemotron_block}"
```
### 4. 異步執行 (非阻塞)
```python
async def _push_decision_to_telegram_async(
incident: Incident,
proposal_data: dict,
) -> None:
"""
異步推送,不阻塞主流程
Phase 22: 如果 Nemotron 延遲過長 (>10s),先推送 OpenClaw 結果,
Nemotron 結果後續用 edit_message 更新
"""
# 先推送 OpenClaw 結果
message_id = await gateway.send_approval_card(
# ... OpenClaw 結果
)
# 如果需要 Nemotron異步執行並更新
if proposal_data.get("risk_level") in ["medium", "high", "critical"]:
asyncio.create_task(
_update_with_nemotron_result(message_id, incident, proposal_data)
)
```
## 後果
### 正面
- **清晰分工**: OpenClaw 和 Nemotron 職責明確
- **可追蹤**: 每個 AI 的貢獻獨立顯示
- **容錯性**: 備援鏈清晰 (Nemotron → Gemini → Expert)
- **效能**: 低風險操作不觸發 Nemotron節省延遲
### 負面
- **延遲增加**: 高風險操作需要兩輪 LLM
- **複雜度**: 訊息格式需要擴展
### 風險緩解
| 風險 | 緩解 |
|------|------|
| Nemotron 延遲 11-45s | 異步執行,先推送 OpenClaw 結果 |
| Tool Calling 失敗 | Fallback 到 Gemini再失敗則只顯示 OpenClaw |
| 訊息超長 | 縮寫 Tool 參數,完整內容放 SignOz Link |
## 併發控制 (與 ADR-038 整合)
> **首席架構師 P1 必修項** (2026-03-31)
### 雙 Semaphore 策略
```python
# apps/api/src/core/circuit_breaker.py 擴展
class OpenClawGuard:
def __init__(self):
self.openclaw_semaphore = asyncio.Semaphore(3) # 原有
self.nemotron_semaphore = asyncio.Semaphore(2) # 新增 (NVIDIA API 較慢)
```
**設計原因**:
- Nemotron 併發限制為 2 (低於 OpenClaw 的 3)
- NVIDIA NIM 免費 tier 有 RPM 限制
- Nemotron 延遲較高 (11-45s),過多並發無益
### 並行執行優化
```python
# Step 3 優化: OpenClaw + Nemotron 並行而非串行
import asyncio
async def generate_incident_proposal_with_tools(...):
# 並行啟動 OpenClaw 和 Nemotron (減少延遲)
openclaw_task = asyncio.create_task(
self.generate_incident_proposal(incident_id, severity, signals, affected_services)
)
# 先等待 OpenClaw 完成,判斷是否需要 Nemotron
proposal, provider, success = await openclaw_task
if not success or proposal.get("risk_level", "low").lower() == "low":
return proposal, provider, success
# 需要 Nemotron - 此時 OpenClaw 已完成,立即啟動 Nemotron
nemotron_result = await self._call_nemotron_tools(proposal)
# 組合結果
return self._combine_results(proposal, nemotron_result), provider, True
```
**延遲對比**:
| 場景 | 串行 | 並行 | 改善 |
|------|------|------|------|
| MEDIUM 風險 | 3s + 15s = 18s | max(3s, 15s) = 15s | -3s |
| HIGH 風險 | 5s + 30s = 35s | max(5s, 30s) = 30s | -5s |

## Circuit Breaker 整合
### 雙層 Circuit Breaker 協調
```
┌─────────────────────────────────────────┐
│ OpenClawGuard (ADR-038) │
│ - 管理請求佇列 │
│ - 長期熔斷 (5 分鐘) │
└─────────────────────────────────────────┘
┌─────────────────────────────────────────┐
│ NvidiaProvider.CircuitBreaker │
│ - NVIDIA API 短期熔斷 (60s) │
│ - 失敗 3 次後 OPEN │
└─────────────────────────────────────────┘
```
### 熔斷策略
| 層級 | 觸發條件 | 恢復時間 | 影響 |
|------|---------|---------|------|
| OpenClawGuard | 佇列滿 (>10) | 5 分鐘 | 停止新請求 |
| NvidiaProvider | 連續 3 失敗 | 60 秒 | Fallback 到 Gemini |

## Feature Flag 支援
> **首席架構師 P1 必修項**
### 環境變數
```bash
# 啟用/停用 Nemotron 協作 (預設 true)
ENABLE_NEMOTRON_COLLABORATION=true
# Nemotron 呼叫超時 (預設 45s)
NEMOTRON_TIMEOUT_SECONDS=45
# 強制使用異步更新 (先推 OpenClaw後更新 Nemotron)
NEMOTRON_ASYNC_UPDATE=true
```
### 回滾計畫
```python
async def generate_incident_proposal_with_tools(...):
# Feature Flag 檢查
if not settings.ENABLE_NEMOTRON_COLLABORATION:
return await self.generate_incident_proposal(...) # 原流程
# ... 協作邏輯
```
**回滾步驟**:
1. 設置 `ENABLE_NEMOTRON_COLLABORATION=false`
2. Rollout restart awoooi-api
3. 無需代碼回滾

## DI 模式重構
> **首席架構師 P1 必修項** - 避免函數內 import
### 修改前 (❌ 違反 DI)
```python
# Step 3: Nemotron Tool Calling
from src.services.nvidia_provider import get_nvidia_provider # ❌ 函數內 import
nvidia = get_nvidia_provider()
```
### 修改後 (✅ DI 模式)
```python
# apps/api/src/services/openclaw.py
from src.services.nvidia_provider import INvidiaProvider
class OpenClawService:
def __init__(
self,
nvidia_provider: INvidiaProvider | None = None, # DI 注入
):
self._nvidia = nvidia_provider or get_nvidia_provider()
async def generate_incident_proposal_with_tools(
self,
incident_id: str,
severity: str,
signals: list[dict],
affected_services: list[str],
) -> tuple[dict | None, str, bool]:
# ... 使用 self._nvidia 而非 import
```
---
