+
+## 核心職責
+
+### 1. 意圖分類 (Intent Classifier)
+
+```
+四大意圖類別:
+┌─────────────┬─────────────────────────────────┐
+│ RESTART     │ 重啟 Pod/Deployment/StatefulSet │
+│ SCALE       │ 擴縮容、HPA 調整                │
+│ CONFIG      │ ConfigMap/Secret/ENV 變更       │
+│ DIAGNOSE    │ 日誌查詢、健康檢查、RCA         │
+└─────────────┴─────────────────────────────────┘
+
+目標延遲: < 100ms (使用 qwen2.5:1b 或規則引擎)
+```
+
+### 2. 複雜度評分 (Complexity Scorer)
+
+```
+1-5 分級:
+┌───┬──────────────────────────────────────────┐
+│ 1 │ 單一資源、無狀態、可立即回滾             │
+│ 2 │ 多資源但同命名空間、低風險               │
+│ 3 │ 跨命名空間、需要上下文收集               │
+│ 4 │ 有狀態資源、需要 Multi-Sig               │
+│ 5 │ 跨叢集、資料庫操作、需要人工審核         │
+└───┴──────────────────────────────────────────┘
+```
+
+### 3. AI Router 決策邏輯
+
+```python
+def select_provider(complexity: int, intent: str) -> str:
+    """
+    動態選擇 AI Provider
+
+    決策矩陣:
+    ┌───────────┬─────────────────────────────┐
+    │ 複雜度 1-2│ Ollama (qwen2.5:7b)         │
+    │ 複雜度 3  │ Ollama → Gemini fallback    │
+    │ 複雜度 4-5│ Gemini → Claude fallback    │
+    └───────────┴─────────────────────────────┘
+
+    例外規則:
+    - DIAGNOSE 意圖: 優先 Ollama (本地日誌，隱私)
+    - 高峰時段: 考慮 Gemini (避免 Ollama 排隊)
+    """
+```
+
+---
+
+## 配置集中管理
+
+### 單一事實來源: `models.json`
+
+```json

+# ❌ 禁止
+model = "qwen2.5:7b-instruct"
+
+# ✅ 正確
+model = model_registry.get_model("ollama", "default")
+```
+
+---
+
+## Token 用量監控
+
+### SignOz Dashboard
+
+```
+關鍵指標:
+- llm.tokens.input: 輸入 Token 數
+- llm.tokens.output: 輸出 Token 數
+- llm.cost.usd: 估算成本 (Cloud Provider)
+- llm.latency.p99: 延遲 P99
+```
+
+### 成本警報閾值
+
+```yaml
+alerts:
+  - name: daily_token_budget
+    threshold: 100000  # tokens/day
+    action: switch_to_local
+  - name: monthly_cost_budget

+# Skill 09: Phase 16 Strangler Pattern Expert
+
+> 版本: v1.0
+> 建立: 2026-03-26 (台北時區)
+> 管轄: 絞殺者模式重構、API 分層架構、漸進式遷移
+
+---
+
+## 觸發條件
+
+修改以下檔案時自動載入:
+- `apps/api/src/api/v1/*.py` (Router 層)
+- `apps/api/src/services/*.py` (Service 層)
+- `apps/api/src/repositories/*.py` (Repository 層)
+- `apps/api/src/_archived/**` (封存區)
+- 任何涉及 **核心邏輯重構** 的任務
+
+---
+
+## 核心原則
+
+> **Why:** Phase 16 驗證了大型重構必須採用漸進式替換，而非一次性重寫。
+
+**三大保證:**
+1. **隨時可回滾** - 環境變數開關切換
+2. **功能不中斷** - 新舊邏輯並存
+3. **可驗證每個階段** - 48 小時觀察期
+
+---
+
+## 絞殺者模式四階段
+
+### Phase 1: Identify (識別)
+
+```
+目標: 標記現有違規代碼，建立 Service 介面，不改變行為
+```
+
+```python
+# 1. 標記需要遷移的代碼
+# @deprecated: Phase 16 - 待遷移至 XxxService (2026-XX-XX)
+def legacy_function():
+    ...
+
+# 2. 建立新 Service 介面 (不實作)
+class IXxxService(Protocol):
+    async def process(self, data: XxxInput) -> XxxOutput: ...
+```
+
+**產出物:**
+- [ ] 違規代碼清單
+- [ ] Service Interface 定義
+- [ ] 遷移計畫文檔
+
+---
+
+### Phase 2: Deprecate (標記棄用)
+
+```
+目標: 新代碼使用 Service，舊代碼加 @deprecated，監控舊路徑使用量
+```
+
+```python
+# 1. 建立環境變數開關
+USE_NEW_ENGINE = os.getenv("USE_NEW_ENGINE", "false").lower() == "true"
+
+# 2. 新舊邏輯並存 (Strangler Wrapper)
+if USE_NEW_ENGINE:
+    result = await new_service.process(data)
+else:
+    result = await legacy_engine.process(data)
+```
+
+**驗證期:** 48 小時觀察，無異常後才進入 Phase 3
+
+**監控指標:**
+- 舊路徑呼叫次數 (SignOz Counter)
+- 錯誤率對比
+- 延遲 P99 對比
+
+---
+
+### Phase 3: Migrate (遷移)
+
+```
+目標: 逐步遷移到 Service，每次遷移有測試覆蓋，回滾計畫就緒
+```
+
+```python
+# 1. 預設啟用新邏輯
+USE_NEW_ENGINE = os.getenv("USE_NEW_ENGINE", "true").lower() == "true"
+
+# 2. 保留舊邏輯作為回滾
+# 3. 封存死代碼到 _archived/
+```
+
+**封存指令:**
+```bash
+# 禁止直接刪除！必須移動到 _archived/
+git mv src/old_module.py src/_archived/old_module.py
+
+# 建立 README 說明回滾方式
+echo "# Archived Code - Phase 16 R2" > src/_archived/README.md
+```
+
+**回滾指令:**
+```bash
+git mv src/_archived/old_module.py src/old_module.py
+kubectl set env deployment/awoooi-api USE_NEW_ENGINE=false
+```
+
+---
+
+### Phase 4: Remove (移除)
+
+```
+目標: 確認無流量，移除舊代碼，更新文檔
+```
+
+**移除條件:**
+- [ ] 30 天觀察期無舊路徑呼叫
+- [ ] 所有測試通過
+- [ ] 統帥確認可刪除
+
+**移除後:**
+- 更新 ADR 文檔
+- 移除環境變數開關
+- 更新 MEMORY.md
+
+---
+
+## Router 層禁止清單 (ADR-024)
+
+```python
+# ❌ 絕對禁止在 Router 層出現
+
+# 1. 直接 Redis 存取
+from src.core.redis_client import get_redis  # ❌
+
+# 2. 直接 DB Session
+from src.db.base import get_session  # ❌
+
+# 3. 直接外部 API 呼叫
+async with httpx.AsyncClient() as client:  # ❌
+    response = await client.get(external_url)
+
+# 4. 內嵌 Lua 腳本
+LUA_SCRIPT = """..."""  # ❌
+
+# 5. 複雜業務邏輯 (>10 行)
+if condition1 and condition2:  # ❌
+    # 複雜處理...
+```
+
+**Router 層允許清單:**
+```python
+# ✅ Router 層可以做的事
+
+# 1. 參數驗證
+@router.get("/items/{item_id}")
+async def get_item(
+    item_id: str = Path(...),
+    limit: int = Query(default=10, ge=1, le=100),
+) -> ItemResponse:
+
+# 2. 權限檢查
+async def get_item(
+    current_user: User = Depends(get_current_user),
+):
+
+# 3. 呼叫 Service
+service = get_item_service()
+result = await service.get_item(item_id)
+
+# 4. 回傳轉換 (簡單)
+return ItemResponse.from_orm(result)
+```

-**問題**: CI LLM 測試全部超時失敗
+**問題識別**: 行動日誌只記錄失敗，沒有後續處理 (死路)
 
-**根因**:
-- Ollama (192.168.0.188) 使用 **CPU 推理**
-- VRAM = 0 GB (未載入 GPU)
-- 生成速度: 0.45 tok/s (正常應 10-20 tok/s)
+**首席架構師提案** (ADR-023):
 
-**待修復**: 需手動檢查 GPU 驅動/CUDA
+```

+```
 
-**決策**:
-- ADR-018 三層框架暫緩整合
-- 先修復 Ollama GPU 問題
-- 再實施方案 A (加 seed 參數)
+**核心元件**:
+- `FailureWatcher` - 監聽失敗事件
+- `RepairAnalyzer` - AI 分析失敗原因
+- `AutoRepairExecutor` - 執行低風險自動修復
+- `RepairLog` - 修復日誌模型
+- `authorization_channel` - 記錄授權來源
+
+**文件**:
+- Memory: `project_phase18_failure_loop.md`
+- ADR: `docs/adr/ADR-023-failure-auto-repair-loop.md`

+### 🔴 2026-03-26 Ollama 伺服器 GPU 診斷 (Day 8 下午 13:00)
 
-**發現問題**:
-- E2E 驗證時發現 AI 產生無效 kubectl 指令
-- 根因: Alert 的 target_resource 傳入 URL 而非 K8s 名稱
-- 例: `kubectl rollout restart deployment/https://api.awoooi.wooo.work` ❌
+**SSH 診斷結果 (192.168.0.188)**:
 
-**已完成 (18.1.1-18.1.5)**:
+| 檢查項目 | 結果 |
+|---------|------|
+| `lspci \| grep nvidia` | **無輸出 - 無 GPU 硬體** |
+| NVIDIA Driver | 未安裝 |
+| NVIDIA Libs | 未找到 |
+| VRAM | 0 GB |
+
+**結論**: 此伺服器為**純 CPU 機器**，無法加速 LLM 推理
+
+**選項**:
+1. 遷移到有 GPU 的主機 (192.168.0.110?)
+2. 接受 CPU 推理速度 (0.45 tok/s)
+3. 使用雲端 LLM 替代 (Gemini/Claude)

+# ADR-023: Phase 13.3 智能路由架構
+
+> **狀態**: 已接受
+> **日期**: 2026-03-26
+> **決策者**: CTO, CEO
+> **相關**: ADR-006 (AI Fallback Strategy), ADR-016 (Smart Routing)
+> **Phase**: 13.3
+
+---
+
+## 1. 背景與問題
+
+### 問題描述
+
+ADR-006 建立了固定順序的 AI 備援策略 (Ollama → Gemini → Claude)，ADR-016 引入了智能路由概念。然而，隨著 AWOOOI 從「告警響應」升級為「全方位 AIOps 平台」(Phase 13)，需要更完整的架構設計：
+
+1. **意圖分類不夠精細**: 缺少針對 K8s 操作的專屬意圖類型
+2. **複雜度評估不完整**: 缺少跨系統、有狀態資源的風險評估
+3. **Token 用量無追蹤**: 無法掌握成本分佈與趨勢
+4. **配置分散**: 模型選擇邏輯散落各處，難以維護
+
+### 目標
+
+- 建立完整的 **Intent → Complexity → Model** 決策流程
+- 定義 K8s 專屬意圖 (RESTART/SCALE/CONFIG/DIAGNOSE)
+- 建立 1-5 分複雜度評分系統
+- 整合 Token 用量監控 (SignOz + Langfuse)
+
+---
+
+## 2. 決策: Intent Classifier + Complexity Scorer + AI Router
+
+### 核心策略
+
+```
+Intent (意圖) + Complexity (複雜度) + Context (上下文) → Model Selection (模型選擇)
+```
+
+### 三元件架構
+
+```

+|------|------|------|
+| `service_count` | +0.5/服務 | 每增加一個受影響服務 |
+| `metric_count` | +0.3/指標 | 每增加一個相關指標 |
+| `cross_namespace` | +1.0 | 跨命名空間操作 |
+| `cross_cluster` | +2.0 | 跨叢集操作 |
+| `stateful_resource` | +1.0 | 有狀態資源 (StatefulSet, PVC) |
+| `database_operation` | +1.5 | 涉及資料庫操作 |
+| `critical_severity` | +1.0 | CRITICAL 嚴重程度 |
+| `has_playbook` | -0.5 | 有歷史 Playbook (降低複雜度) |

+| **4** | 高複雜 | 有狀態資源、需要 Multi-Sig | StatefulSet 操作 |
+| **5** | 極複雜 | 跨叢集、資料庫操作、需要人工審核 | 資料庫 Schema 變更 |

+## 9. 後果分析
+
+### 優點
+
+| 面向 | 效益 |
+|------|------|
+| **資源優化** | 簡單任務用小模型 (3B)，節省 GPU 資源 30%+ |
+| **品質提升** | 複雜任務自動升級到強模型，減少人工介入 |
+| **成本可控** | 只有真正需要時才使用雲端 API |
+| **延遲改善** | 簡單查詢回應 < 5s (llama3.2:3b) |
+| **可觀測性** | Token 用量透明，成本趨勢可預測 |
+| **隱私保護** | DIAGNOSE 意圖強制本地，敏感日誌不送雲端 |
+
+### 缺點
+
+| 面向 | 風險 | 緩解措施 |
+|------|------|---------|
+| **分類錯誤** | 意圖分類可能有邊界情況 | 關鍵字優先 + LLM 備援 |
+| **複雜度誤判** | 規則可能需要持續調優 | 收集數據 + 定期調整權重 |
+| **延遲增加** | 分類 + 評分 增加約 100ms | 限制 LLM 分類僅作備援 |
+| **維護成本** | 需維護關鍵字映射表 | 集中管理於 models.json |
+
+### 風險
+
+| 風險 | 等級 | 緩解策略 |
+|------|------|---------|
+| LLM 分類器 Timeout | 中 | 設定 100ms Timeout，fallback 到 UNKNOWN |
+| 全部 Provider 失敗 | 低 | ADR-006 靜態回應兜底 |
+| Token 預算超支 | 中 | 告警閾值 70%，超支自動切本地 |
+| 意圖覆寫邏輯錯誤 | 低 | 嚴格測試 + 監控路由決策分佈 |

+| **狀態** | ✅ 已採用 |
+| **日期** | 2026-03-26 |
+| **決策者** | 首席架構師 + 統帥 |
+| **Phase** | Phase 16 |
+
+## 背景
+
+Phase 16 架構大掃除需要明確的 API 分層規範，以支援絞殺者模式 (Strangler Fig Pattern) 的漸進式重構。
+
+當前問題：
+- Router 層存在業務邏輯 (32 項違規)
+- 配置分散在多處
+- 缺乏明確的層級邊界
+
+## 決策
+
+採用 **四層架構** 標準：
+
+```

+## Router 層禁止清單
+
+```python
+# ❌ 禁止在 Router 層做的事
+
+# 1. 直接 Redis 存取
+from src.core.redis_client import get_redis  # ❌
+
+# 2. 直接 DB Session
+from src.db.base import get_session  # ❌
+
+# 3. 直接外部 API 呼叫
+async with httpx.AsyncClient() as client:  # ❌
+    response = await client.get(external_url)
+
+# 4. 內嵌 Lua 腳本
+LUA_SCRIPT = """..."""  # ❌
+
+# 5. 複雜業務邏輯 (>10 行)
+if condition1 and condition2:  # ❌
+    # 複雜處理...
+```
+
+## Router 層允許清單
+
+```python
+# ✅ Router 層可以做的事
+
+# 1. 參數驗證
+@router.get("/items/{item_id}")
+async def get_item(
+    item_id: str = Path(...),
+    limit: int = Query(default=10, ge=1, le=100),
+) -> ItemResponse:
+
+# 2. 權限檢查
+async def get_item(
+    current_user: User = Depends(get_current_user),
+):
+
+# 3. 呼叫 Service
+service = get_item_service()
+result = await service.get_item(item_id)
+
+# 4. 回傳轉換 (簡單)
+return ItemResponse.from_orm(result)

+
+## 後果
+
+### 正面
+- 清晰的層級邊界
+- 可測試性提升 (每層獨立測試)
+- 漸進式遷移，低風險
+
+### 負面
+- 短期開發成本增加
+- 需要團隊學習新規範
