-# Harmonic CMTS Manager - AI 開發守則與架構白皮書
+# Harmonic CMTS Manager - AI Architect Guidelines & System Blueprint
 
-## 1. 專案架構概覽與技術棧
-- **定位**: 專為有線電視網路終端設備 (CMTS) 設計的企業級 Web 管理系統。
-- **後端**: Python 3.10+, FastAPI (Async-first), AsyncSSH, Netmiko, asyncpg.
-- **前端**: 原生 Vanilla JS (ES Modules), HTML5, CSS3, Xterm.js.
-- **資料庫**: PostgreSQL (主要), JSON File Cache (高可用性降級備援).
+> **⚠️ AI 角色與絕對約束 (AI Persona & Absolute Directives)**
+> 你現在是一位資深的系統架構師與全端工程師。
+> 1. **唯一真理**：絕對禁止自行幻想任何不存在的模組、變數或第三方套件。所有修改必須基於現有架構。
+> 2. **語言規範**：註解、對話與 Git Commit 一律使用**繁體中文 (zh-TW)**。
+> 3. **無聲錯誤是原罪**：所有後端 API 必須使用 `try-except` 捕捉例外，並回傳標準 JSON `{"status": "error", "message": "..."}`，嚴禁 FastAPI 直接拋出 HTTP 500 導致前端崩潰。
 
-### 📂 目錄與檔案結構
-- **進入點**: `main.py`
-- **路由管理**: API 路由統一放置於 `routers/` 目錄。包含 backup.py, config.py, leaf_options.py, lock.py, query.py, terminal.py。
-- **前端介面**: `index.html` 與 `static/` 目錄。 包含 api.js, app.js, edit-mode.js, mac-domain.js, style.css, terminal.js, tree-ui.js, utils.js。
-- **核心邏輯**: 
-  - `cmts_scraper.py`: 負責底層爬蟲與資料處理。
-  - `shared.py`: 放置共用函式 (如兩階段解析法)。
-  - `config.py`: 配置轉譯器 (CLI Generator)。
-- **資料庫**: 連線與 ORM 邏輯在 `database.py`，初始化腳本為 `init_db.py`。
-- **併發控制**: `lock.py` (路徑階層鎖), `leaf_options.py` (SSE 頻道分流)。
+---
 
-## 2. 核心架構與業務邏輯 (Architecture & Logic)
-- **兩階段解析法**: 依賴「縮排」與「`!`」劃分區塊，並動態降維成深層巢狀結構，使用 `deep_merge` 確保資料不遺失。
-- **動態探測**: 透過發送 `[指令] ?` 動態學習資料結構，並採用 `BATCH_SIZE = 30` 搭配 `asyncio.sleep()` 進行非同步批次處理。
-- **絕對路徑與 Commit 機制 (Absolute Path)**: Harmonic CMTS 支援從 Global 模式直接寫入帶有完整上下文的絕對路徑指令（如 `cable mac-domain 13:0/0.0 ...`），無須層層進入子模式。所有變更指令發送完畢後，必須執行 `commit` 才能生效。
-- **智慧差異還原 (Smart Diff Recovery)**: 設備還原不採用盲目覆蓋，而是透過深度比對 (Deep Diff) 當前設備狀態與備份快照，動態生成包含 `no` 的反向刪除指令與新增/修改指令，確保配置精準還原且無殘留。
-- **併發與狀態廣播**: 支援「父子繼層攔截」的路徑階層鎖，並利用 `asyncio.Queue` 實作 SSE 頻道分流，即時推播進度。
-- **配置轉譯器**: 自動補齊父層級路徑，處理 `no [指令]` 刪除邏輯，並具備 `admin-state` 的生命週期防呆機制。
+## 🏗️ 1. 系統總體架構 (System Architecture)
 
-## 3. 🚨 AI 開發絕對約束 (Directives for AI)
+本系統為專為 Harmonic CableOS 設計的企業級 Web 管理介面，採用前後端分離架構，並透過 WebSocket 與 SSE 實現即時雙向通訊。
 
-### ⚙️ 系統與環境規範
-1. **套件管理**: 若需安裝新套件，請提醒我手動在 `cmts_api_env` 中安裝，並更新 `requirements.txt`。
-2. **資料讀取限制**: 請勿隨意讀取 `*_cache.json` 檔案的內容，若需了解資料結構，請參考 `cmts_scraper.py` 中的定義。
-3. **狀態同步**: 完成重大修改或一個 Phase 後，必須主動更新 `PROJECT_STATE.md` 記錄最新進度與待辦事項。
+*   **後端 (Backend)**: Python 3.10+, FastAPI (Async-first), `asyncssh` (核心連線引擎), `asyncpg` (資料庫連線池)。
+*   **前端 (Frontend)**: Vanilla JS (ES Modules), HTML5, CSS3 (CSS Variables, Content-Visibility), Xterm.js, Chart.js。
+*   **資料庫 (Database)**: PostgreSQL (`cmts_nms` 資料庫)。
 
-### 💻 程式碼風格與後端規範
-4. **語言與風格**: 註解與對話請一律使用**繁體中文**。Python 程式碼請遵循 PEP8 規範，並加上適當的 Type Hints (型別提示)。
-5. **Async-First (非同步絕對優先)**: 嚴禁使用阻塞的同步 I/O。同步函數必須封裝進 `await asyncio.to_thread()`。
-6. **嚴守「雙軌並行」**: 必須在任何 API 請求明確傳遞並驗證 `config_type` ('running' 或 'full')。絕對禁止 `running` 污染 `full` 快取。
-7. **無痛切換 (Feature Toggle)**: 必須保留 `USE_DB` 開關，若 DB 連線異常，必須能自動退回使用 JSON 檔案讀寫。
-8. **無聲錯誤是原罪**: 所有設備互動模組必須使用 `try-except`，並回傳標準 JSON `{"status": "error", "message": "..."}`。嚴禁 FastAPI 直接拋出 500。
-9. **CLI 執行策略 (Absolute Path Strategy)**: 針對設備寫入或還原設定時，一律採用「絕對路徑」指令，無需模擬傳統 Cisco IOS 的模式切換。寫入腳本的結尾或區塊末端，務必加上 `commit`。
-10. **精準 Prompt 偵測**: 透過 SSH 讀取設備回傳時，嚴禁盲目依賴 `timeout`。必須在 `read_until_quiet` 中傳入 `prompt_pattern` (如 `r"\(config\)#"` 或 `r"(?:#|>)"`) 進行正規表達式匹配，以最高速釋放資源。
+---
 
-### 🎨 前端規範
-11. **DOM 神聖不可侵犯**: 在前端 JS 中，嚴禁為了視覺美化刪除 `leaf-container`, `data-path`, `data-original` 等錨點。隱藏請用 `display: none`。
-12. **UI 狀態安全還原**: 動態修改 DOM 的 CSS 屬性（如 `flex`, `width`）後，若需恢復原狀，嚴禁寫死預設值，必須將屬性設為空字串 `''`，讓瀏覽器自然退回 HTML 定義的樣式，避免改 A 壞 B。
-13. **設備操作原子性 (Atomicity)**：任何涉及「讀取後寫入」或「備份後寫入」的設備操作，必須確保嚴格的先後順序（使用 `await`），嚴禁使用 `BackgroundTasks` 導致 Race Condition。若過程耗時，必須透過 SSE 或 ReadableStream 即時回報進度。
-14. **資料庫防膨脹原則**：實作任何會自動產生大量資料的功能（如自動備份、日誌），必須同時實作 Retention Policy（保留策略/定期清理機制），不可只寫入不刪除。
-15. **安全還原原則 (Safe Restore)**: 嚴禁直接將整份備份檔盲目寫入設備。任何還原操作必須遵循「三階段流程」：產生差異 (Diff) ➡️ 前端預覽 (Preview) ➡️ 授權執行 (Commit)。
-16. **前端防禦性編程 (Defensive Programming)**: 處理 API 回傳資料、DOM 元素取值或陣列過濾時，必須嚴格防範 Null/Undefined 情況（例如使用 `(item.description || '').toLowerCase()` 與 `?.` 運算子）。確保前端 UI 絕對不會因為單一欄位資料缺失或舊版快取而導致整個畫面或功能崩潰。
+## 🧩 2. 模組化切割與檔案關聯 (Module Map)
+
+### 🟢 後端核心模組 (Backend Core)
+*   `main.py`: 系統進入點。負責掛載靜態檔案、初始化 DB Pool (`lifespan`)，並將所有 API 路由統一掛載於 `/api/v1` 前綴之下。
+*   `database.py`: PostgreSQL 非同步連線池管理。嚴格區分 `running` 與 `full` 的 `config_type` 雙軌隔離設計。
+*   `cmts_scraper.py`: 底層 SSH 爬蟲引擎。負責發送 `?` 探測設備選項、解析終端機分頁 (`--More--`)，並清理 ANSI 控制碼。
+*   `shared.py`: 純邏輯共用區。包含核心的 `parse_cli_to_tree` (兩階段解析法)、`deep_split_tree` (降維展開)，以及全域的 `cmts_config_locks` (依 IP 隔離的非同步鎖)。
+*   `logger.py`: 具備 ANSI 色彩的自訂日誌系統，支援透過 API 動態調整各模組的 Log Level。
+
+### 🔵 後端路由模組 (Routers - `/routers/`)
+*   `config.py`: 負責抓取完整配置 (`/cmts-full-config`)、套用系統過濾器，以及將前端 Diff 轉譯為 CLI 腳本 (`generate_cli`)。
+*   `leaf_options.py`: 負責選項快取的背景掃描，並透過 `asyncio.Queue` 實作 SSE (Server-Sent Events) 頻道分流，即時推播掃描進度。
+*   `lock.py`: 實作 In-Memory 的路徑階層鎖 (`ACTIVE_LOCKS`)，支援 Heartbeat 續命與過期自動清理。
+*   `backup.py`: 設備快照與還原中心。實作 Deep Diff 演算法，並透過 `StreamingResponse` (NDJSON) 實作具備 Fail-safe (自動 `abort`) 的安全還原管道。
+*   `query.py`: 處理標準 `show` 指令查詢，以及 MAC Domain 的互動式解析。
+*   `diagnostics.py`: 深度解析 CM 狀態，包含 PHY 功率、SNR 與 OFDM MER 陣列。
+*   `terminal.py`: WebSocket 代理，將前端 Xterm.js 的輸入轉發至 `asyncssh` 的 PTY。
+
+### 🟡 前端模組 (Frontend - `/static/`)
+*   `app.js`: 主協調器 (Orchestrator)。負責頁籤切換、SSE 監聽初始化、全域鎖定狀態輪詢 (`startLockStatusPolling`) 與 God Mode 授權。
+*   `api.js`: 純粹的 Fetch API 封裝層，負責與後端 `/api/v1` 溝通。
+*   `tree-ui.js`: **效能核心**。負責將 JSON 轉換為 HTML 樹狀圖。採用「記憶體遞迴渲染」與「延遲載入 (`lazyLoadFolder`)」。
+*   `edit-mode.js`: 編輯狀態機。處理鎖定獲取、UI 狀態切換 (✏️ -> 🔒 -> ⏳)、生成 Diff 陣列，以及右側 CLI 預覽面板的控制。
+*   `mac-domain.js`: 獨立的 MAC Domain 狀態感知配置精靈邏輯。
+*   `terminal.js`: Xterm.js 實例化、WebSocket 連線管理與終端機字串上色 (`colorizeTerminalStream`)。
+
+---
+
+## 🚀 3. 核心演算法與開發規範 (Core Mechanisms & Rules)
+
+### ⚡ 3.1 前端極致效能規範 (Extreme DOM Performance)
+本系統的 DOM 節點可能高達數萬個，**嚴禁使用同步迴圈大量操作 DOM**。
+1.  **記憶體遞迴渲染 (In-Memory Rendering)**：在 `tree-ui.js` 中，必須先在 JS 記憶體中將 HTML 字串完全組裝完畢，最後只執行 **1 次** `innerHTML` 寫入。
+2.  **非同步 UI 保護**：任何大型渲染（如展開全部、初始載入），必須先顯示 `⏳ 載入中...` 並將游標設為 `wait`，接著使用 `setTimeout(..., 20)` 讓出主執行緒，確保瀏覽器不卡死。
+3.  **CSS 渲染隔離**：依賴 `style.css` 中的 `content-visibility: auto;`，嚴禁在 JS 中破壞 `.tree-folder-content` 的結構。
+
+### 🔒 3.2 併發與鎖定機制 (Concurrency & Locking)
+1.  **IP 隔離原則**：所有的鎖定 Key 必須是 `host@@path` 格式，確保不同設備間的鎖定互不干擾。
+2.  **父子階層鎖 (Cascading Lock)**：前端在輪詢鎖定狀態時，必須檢查「自身」、「父節點」與「子節點」的鎖定衝突。
+3.  **防閃爍冷卻 (Optimistic UI Cooldown)**：前端主動釋放鎖定後，必須將該 Key 寫入 `recentlyReleasedLocks` (冷卻 8 秒)，防止後端狀態未同步導致的 UI 閃爍。
+
+### 🛡️ 3.3 設備寫入與安全還原 (Safe SSH Execution)
+1.  **絕對路徑策略 (Absolute Path)**：寫入設備時，一律生成帶有完整上下文的絕對路徑指令（如 `cable mac-domain 13:0/0.0 admin-state down`），嚴禁依賴傳統的層層進入模式。
+2.  **Fail-safe 撤銷機制**：在 `backup.py` 與 `config.py` 的寫入迴圈中，只要偵測到設備回傳 `% Invalid`, `% Incomplete` 或 `Error`，必須**立即停止寫入**，並向設備發送 `abort` 指令放棄所有變更。
+3.  **精準 Prompt 偵測**：使用 `asyncssh` 讀取輸出時，嚴禁盲目等待 Timeout。必須在 `read_until_quiet` 中傳入精準的 `prompt_pattern` (如 `r"\(config.*\)#"` 或 `r"(?:#|>)"`)。
+
+### 🌳 3.4 樹狀圖解析與資料結構 (Tree Parsing)
+1.  **兩階段解析**：`shared.py` 中的 `parse_cli_to_tree` 必須先依賴「縮排」建立實體樹，再透過 `deep_split_tree` 將空白分隔的字串降維成深層巢狀 JSON。
+2.  **終極衝突保護**：在合併字典時，若遇到「資料夾」與「字串」的型態衝突，必須自動升級為資料夾，並將原字串保留至虛擬鍵 `[0]`, `[1]` 中，**絕對不允許遺失任何設備配置**。
+3.  **雙軌記憶體**：前端 `window.treeDataStore` 必須嚴格區分 `running` 與 `full`，切換視圖時純粹切換 CSS `display`，不銷毀資料。
