-# MES Dashboard（README.mdj）
-
-本文件為 `README.md` 的精簡技術同步版，聚焦目前可運行架構與運維契約。
-
-## 1. 架構摘要（2026-02-08）
-
-- 後端：Flask + Gunicorn（單一 port）
-- 前端：Vite build 輸出到 `src/mes_dashboard/static/dist`
-- 快取：Redis + process-level cache + indexed selection telemetry
-- 資料：Oracle（QueuePool）
-- 運維：watchdog + admin worker restart API + guarded-mode policy
-- 環境設定：開發與正式環境統一使用專案根目錄同一份 `.env`
-- 啟動腳本：`./scripts/start_server.sh start` 會同時啟動 Gunicorn 與 `worker_watchdog.py`
-
-## 2. 既有設計原則（保留）
-
-- `resource`（設備基礎資料）與 `wip`（線上即時狀況）維持全表快取策略。
-- 前端頁面邏輯與 drill-down 操作語意維持不變。
-- 系統維持單一 port 服務模式（前後端同源）。
-
-## 3. P0 Runtime Hardening（已完成）
-
-- Production 強制 `SECRET_KEY`：未設定或使用不安全預設值時，啟動直接失敗。
-- CSRF 防護：
-  - `/admin/login` 表單需 token
-  - `/admin/api/*` 的 `POST/PUT/PATCH/DELETE` 需 `X-CSRF-Token`
-- Session hardening：登入成功後 `session.clear()` + CSRF token rotation。
-- Health probe isolation：`/health` DB 連通檢查使用獨立 health pool。
-- Shutdown cleanup：統一停止 cache updater、equipment sync worker，並關閉 Redis 與 DB engine。
-- XSS hardening：`hold_detail` fallback script 的 `reason` 改用 `tojson`。
-
-## 4. P1 Cache/Query Efficiency（已完成）
-
-- `resource` / `wip` 仍維持全表快取策略（業務約束不變）。
-- WIP 查詢改走 indexed selection，並加入增量同步（watermark/version）與 drift fallback。
-- `/health`、`/health/deep`、`/admin/api/system-status` 提供 cache memory amplification/index telemetry。
-- 新增 benchmark harness：`scripts/run_cache_benchmarks.py --enforce`。
-
-## 5. P2 Ops Self-Healing（已完成）
-
-- runtime contract 共用化：app/start_server/watchdog/systemd 使用同一組 watchdog/conda 路徑契約。
-- 啟動 fail-fast：conda/runtime path drift 時拒絕啟動並輸出可操作診斷。
-- worker restart policy：cooldown + retry budget + churn guarded mode。
-- manual override：需 admin 身分 + `manual_override` + `override_acknowledged` + `override_reason`，且寫入 audit log。
-- health/admin payload 提供 policy state：`allowed` / `cooldown` / `blocked`。
-
-## 6. Round-3 Residual Hardening（已完成）
-
-- WIP cache publish 改為 staged publish，更新失敗不覆寫舊快照。
-- WIP process cache slow-path parse 移到鎖外，降低 lock contention。
-- realtime equipment process cache 補齊 bounded LRU（含 `EQUIPMENT_PROCESS_CACHE_MAX_SIZE`）。
-- `_clean_nan_values` 改為 depth-safe 迭代式清理（避免深層遞迴風險）。
-- WIP/Hold/Resource bool query parser 共用化（`core/utils.py`）。
-- filter cache source view 可由 env 覆寫（便於環境切換與測試）。
-- `/health`、`/health/deep` 增加 5 秒 memo（testing 模式自動關閉）。
-- 高成本 API 增加輕量 in-process rate limit，超限回傳一致 429 結構。
-- DB 連線字串記錄加上敏感欄位遮罩（密碼 redaction）。
-
-## 7. Round-4 Residual Consolidation（已完成）
-
-- Resource derived index 改為 row-position representation，不再在 process 內保存 full records 複本。
-- Resource / Realtime Equipment 共用 Oracle SQL fragments，避免查詢定義重複漂移。
-- `resource_cache` / `realtime_equipment_cache` 型別註記風格與高頻常數命名收斂。
-- `page_registry` 寫檔改為 atomic replace，降低設定檔半寫入風險。
-- 新增測試覆蓋 shared SQL fragment 與 bool parser 不重複定義治理。

+## Context
+
+目前系統有 11 個頁面，全部使用 Jinja2 shell + Vite JS 混合模式。前端無 UI 框架（純 vanilla JS），ECharts 以靜態 minified 檔案引入（非 npm）。WIP 資料透過 Redis 快取，每 10 分鐘從 Oracle DWH.DW_MES_LOT_V 同步。
+
+QC-GATE 頁面將是第一個採用 Vue 3 + Vite 純前端架構的頁面，建立後續遷移模式。
+
+## Goals / Non-Goals
+
+**Goals:**
+- 提供 QC-GATE 站點即時 LOT 狀態報表（條圖 + 篩選清單）
+- 建立純 Vue 3 + Vite 頁面架構模式（不依賴 Jinja2）
+- 與現有 portal iframe 機制無縫整合
+- 複用現有 WIP Redis 快取，不增加 Oracle 查詢負擔
+
+**Non-Goals:**
+- 不遷移現有頁面到 Vue 3（本次僅建立模式）
+- 不引入 Vue Router 或 Pinia（單頁報表不需要）
+- 不修改現有 CSP 或安全策略
+- 不改動 WIP 快取更新機制
+
+## Decisions
+
+### D1: UI 框架選型 — Vue 3
+
+**選擇**: Vue 3 (Composition API + SFC)
+**替代方案**: React (JSX 轉換成本較高), Svelte (生態系較小)
+**理由**: Vite 原生支援、template 語法接近 Jinja 降低遷移門檻、vue-echarts 整合成熟、支持漸進式頁面遷移
+
+### D2: 頁面服務方式 — Vite MPA HTML entry + Flask 靜態服務
+
+**選擇**: Vite build 產出完整 HTML (`frontend/src/qc-gate/index.html`)，Flask 以 `send_from_directory` 服務
+**替代方案**: 最小 Jinja shell（仍有 Jinja 依賴）
+**理由**:
+- 完全脫離 Jinja2，建立乾淨的遷移模式
+- 此頁面為唯讀報表，只有 GET 請求，不需要 CSRF token 注入
+- Toast 功能由 Vue component 自行實作（不依賴 `_base.html` 的全域 toast）
+- Vite config 已有 `manualChunks` 設定，只需新增 HTML entry
+
+### D3: ECharts 引入方式 — npm + tree-shaking
+
+**選擇**: `npm install echarts vue-echarts`，使用 tree-shaking 只引入 bar chart 相關模組
+**替代方案**: 繼續使用靜態 minified 檔案（無法 tree-shake，~1MB）
+**理由**: 既有 Vite config 已有 `vendor-echarts` chunk split 邏輯；npm 引入後可 tree-shake 到只需 bar chart 模組（~200KB gzipped）
+
+### D4: API 設計 — 新增 `/api/qc-gate/summary` 端點
+
+**選擇**: 新建 `qc_gate_routes.py` blueprint + `qc_gate_service.py` 服務
+**替代方案**: 擴展現有 wip_routes（不符合 SRP）
+**理由**:
+- 從 WIP Redis 快取中讀取，篩選 `SPECNAME LIKE '%QC%GATE%'`
+- 使用 `DW_MES_SPEC_WORKCENTER_V`（已在 filter_cache.py 中快取）取得站點排序
+- 在後端完成 6HR 分級計算，前端只負責渲染
+- 回傳結構包含 summary（條圖資料）和 lots（清單資料）
+
+### D5: QC-GATE 站點識別與排序
+
+**選擇**: 從 WIP 快取篩選 `SPECNAME` 包含 "QC" 和 "GATE" 的 LOT，站點排序從 `DW_MES_SPEC_WORKCENTER_V` 的 `SPEC` 欄位匹配取得 `SPEC_ORDER`
+**理由**: SPECNAME 是 LOT 層級的製程步驟名稱，DW_MES_SPEC_WORKCENTER_V 是維度主表提供排序資訊
+
+### D6: 等待時間分級
+
+**選擇**: 四級分組
+- `< 6hr` — 正常（綠色）
+- `6-12hr` — 注意（黃色）
+- `12-24hr` — 警告（橙色）
+- `> 24hr` — 超時（紅色）
+
+**計算**: `wait_hours = (SYS_DATE - MOVEINTIMESTAMP)` 以小時為單位，在後端計算
+
+### D7: 自動刷新 — 複用 wip-overview 模式
+
+**選擇**: 10 分鐘 `setInterval` + `visibilitychange` 即時刷新
+**理由**: 與 WIP 快取同步週期一致，避免無效請求；tab 隱藏時跳過刷新

+
+## Vite Config Changes
+
+```js
+// vite.config.js additions
+import vue from '@vitejs/plugin-vue';
+
+export default defineConfig({
+  plugins: [vue()],
+  build: {
+    rollupOptions: {
+      input: {
+        // ... existing entries ...
+        'qc-gate': resolve(__dirname, 'src/qc-gate/index.html')  // HTML entry
+      },
+      output: {
+        manualChunks(id) {
+          if (!id.includes('node_modules')) return;
+          if (id.includes('echarts')) return 'vendor-echarts';
+          if (id.includes('vue')) return 'vendor-vue';  // 新增 Vue chunk
+          return 'vendor';
+        }
+      }
+    }
+  }
+});
+```
+
+## Risks / Trade-offs
+
+- **[Vue plugin 影響既有 build]** → `@vitejs/plugin-vue` 只處理 `.vue` 檔案，不影響現有 `.js` entry points。已驗證 Vite plugin 系統為 additive。
+- **[ECharts npm vs 靜態檔案共存]** → 新頁面用 npm echarts，舊頁面繼續用靜態檔案。`vendor-echarts` chunk 只被 qc-gate 引用，不影響舊頁面 bundle size。
+- **[SPECNAME pattern 可能變動]** → 篩選邏輯集中在 `qc_gate_service.py` 單一位置，易於調整。
+- **[純靜態 HTML 無法使用 Flask template context]** → 此頁面為唯讀報表，不需要 CSRF、不需要 session 資料。認證由 portal iframe 外層處理。

+## Why
+
+目前系統缺乏 QC-GATE 站點的即時 LOT 狀態監控。QC-GATE 是製程中的品質關卡，LOT 在此站點的等待時間直接影響生產效率。需要一個視覺化報表即時呈現各 QC-GATE 站點的 LOT 分佈與等待時間，讓管理者快速識別瓶頸。
+
+此頁面同時作為前端架構遷移的起點 — 第一個完全脫離 Jinja2 的純 Vue 3 + Vite 頁面，為後續頁面遷移建立模式。
+
+## What Changes
+
+- 新增 QC-GATE 即時狀態報表頁面（`/qc-gate`），使用 Vue 3 + ECharts 實作
+- 新增後端 API endpoint（`/api/qc-gate/summary`），從 WIP Redis cache 篩選 QC-GATE 相關 LOT
+- 前端引入 Vue 3 和 ECharts npm 套件，建立純 Vite 頁面架構模式
+- 頁面以 Vite HTML entry 方式建置，完全不使用 Jinja2 template
+- 頁面註冊至「報表類」drawer，狀態為 released
+- 使用 `DW_MES_SPEC_WORKCENTER_V` 取得 QC-GATE 站點清單與排序
+- 等待時間以 6 小時為基準分為四級：<6hr, 6-12hr, 12-24hr, >24hr
+- 支援 10 分鐘自動刷新與 visibilitychange 即時刷新
+
+## Capabilities
+
+### New Capabilities
+- `qc-gate-status-report`: QC-GATE 站點即時 LOT 狀態報表 — 包含 API 端點、Vue 3 前端頁面、圖表互動、清單篩選
+- `vue-vite-page-architecture`: 純 Vue 3 + Vite 頁面架構模式 — 脫離 Jinja2 的前端建置模式、CSRF/auth 處理、與 portal iframe 整合
+
+### Modified Capabilities
+- `page-drawer-assignment`: 新增 qc-gate 頁面至報表類 drawer 的 page_status.json 配置
+
+## Impact
+
+- **前端**: 引入 `vue`、`echarts`、`vue-echarts` npm 依賴；修改 `vite.config.js` 加入 Vue plugin 和新 entry point
+- **後端**: 新增 `qc_gate_routes.py` blueprint 和 `qc_gate_service.py` 服務；新增 Flask route serving 純靜態 HTML
+- **配置**: `page_status.json` 新增 qc-gate 頁面定義
+- **建置**: Vite config 需加入 `@vitejs/plugin-vue` 和 HTML entry

+## ADDED Requirements
+
+### Requirement: System SHALL provide QC-GATE LOT status API
+The system SHALL provide an API endpoint that returns real-time LOT status for all QC-GATE stations, with wait time classification.
+
+#### Scenario: Retrieve QC-GATE summary
+- **WHEN** user sends GET `/api/qc-gate/summary`
+- **THEN** the system SHALL return all LOTs whose `SPECNAME` contains both "QC" and "GATE" (case-insensitive)
+- **THEN** each LOT SHALL include `wait_hours` calculated as `(SYS_DATE - MOVEINTIMESTAMP)` in hours
+- **THEN** each LOT SHALL be classified into a time bucket: `lt_6h`, `6h_12h`, `12h_24h`, or `gt_24h`
+- **THEN** the response SHALL include per-station bucket counts and the full lot list
+
+#### Scenario: QC-GATE data sourced from WIP cache
+- **WHEN** the API is called
+- **THEN** the system SHALL read from the existing WIP Redis cache (not direct Oracle query)
+- **THEN** the response SHALL include `cache_time` indicating the WIP snapshot timestamp
+
+#### Scenario: No QC-GATE lots in cache
+- **WHEN** no LOTs match the QC-GATE SPECNAME pattern
+- **THEN** the system SHALL return an empty `stations` array with `cache_time`
+
+### Requirement: QC-GATE stations SHALL be ordered by spec sequence
+The system SHALL order QC-GATE stations according to the manufacturing flow sequence from `DW_MES_SPEC_WORKCENTER_V`.
+
+#### Scenario: Station ordering
+- **WHEN** the API returns multiple QC-GATE stations
+- **THEN** the stations SHALL be sorted by `SPEC_ORDER` from `DW_MES_SPEC_WORKCENTER_V` where `SPEC` matches the SPECNAME
+
+#### Scenario: Station not found in spec dimension table
+- **WHEN** a QC-GATE SPECNAME is not found in `DW_MES_SPEC_WORKCENTER_V`
+- **THEN** the station SHALL appear at the end of the list with a high default sort order
+
+### Requirement: QC-GATE report page SHALL display stacked bar chart
+The page SHALL display a stacked bar chart showing LOT counts per QC-GATE station, grouped by wait time bucket.
+
+#### Scenario: Bar chart rendering

+## 1. Frontend Toolchain Setup
+
+- [x] 1.1 Install npm dependencies: `vue`, `@vitejs/plugin-vue`, `echarts`, `vue-echarts`
+- [x] 1.2 Update `vite.config.js`: add Vue plugin, add `qc-gate` HTML entry point, add `vendor-vue` manual chunk
+
+## 2. Backend API
+
+- [x] 2.1 Create `services/qc_gate_service.py`: read WIP cache, filter SPECNAME by QC/GATE pattern, compute wait_hours and bucket classification, sort stations by SPEC_ORDER from filter_cache
+- [x] 2.2 Create `routes/qc_gate_routes.py`: blueprint with `GET /api/qc-gate/summary` endpoint
+- [x] 2.3 Register blueprint in `routes/__init__.py` and add Flask route `GET /qc-gate` serving static HTML via `send_from_directory`
+
+## 3. Vue Frontend Page
+
+- [x] 3.1 Create `frontend/src/qc-gate/index.html`: standalone HTML entry with Vue app mount point
+- [x] 3.2 Create `frontend/src/qc-gate/main.js`: Vue app bootstrap with createApp and mount
+- [x] 3.3 Create `frontend/src/qc-gate/App.vue`: root layout with header (title, cache time, refresh button), chart area, and table area
+- [x] 3.4 Create `frontend/src/qc-gate/composables/useQcGateData.js`: data fetching, 10min auto-refresh with visibilitychange, reactive state management
+- [x] 3.5 Create `frontend/src/qc-gate/components/QcGateChart.vue`: ECharts stacked bar chart (x=station, y=count, stacked by 4 time buckets with color coding)
+- [x] 3.6 Create `frontend/src/qc-gate/components/LotTable.vue`: sortable lot table with click-to-filter from chart, filter indicator, clear filter
+- [x] 3.7 Create `frontend/src/qc-gate/style.css`: page styling consistent with existing dashboard aesthetic
+
+## 4. Page Registration & Integration
+
+- [x] 4.1 Register qc-gate page in `page_status.json`: route `/qc-gate`, name `QC-GATE 狀態`, drawer_id `reports`, status `released`
+- [x] 4.2 Build frontend (`npm run build`) and verify output files exist in `static/dist/`
+
+## 5. Verification
+
+- [x] 5.1 Verify API endpoint returns correct data structure with QC-GATE filtered lots, wait time buckets, and station ordering
+- [x] 5.2 Verify page renders in portal iframe: chart displays, table populates, click-to-filter works, auto-refresh fires
+- [x] 5.3 Verify existing pages still build and function correctly (Vue plugin does not break vanilla JS entries)

+## Purpose
+Define stable requirements for qc-gate-status-report.
+
+## Requirements
+
+
+### Requirement: System SHALL provide QC-GATE LOT status API
+The system SHALL provide an API endpoint that returns real-time LOT status for all QC-GATE stations, with wait time classification.
+
+#### Scenario: Retrieve QC-GATE summary
+- **WHEN** user sends GET `/api/qc-gate/summary`
+- **THEN** the system SHALL return all LOTs whose `SPECNAME` contains both "QC" and "GATE" (case-insensitive)
+- **THEN** each LOT SHALL include `wait_hours` calculated as `(SYS_DATE - MOVEINTIMESTAMP)` in hours
+- **THEN** each LOT SHALL be classified into a time bucket: `lt_6h`, `6h_12h`, `12h_24h`, or `gt_24h`
+- **THEN** the response SHALL include per-station bucket counts and the full lot list
+
+#### Scenario: QC-GATE data sourced from WIP cache
+- **WHEN** the API is called
+- **THEN** the system SHALL read from the existing WIP Redis cache (not direct Oracle query)
+- **THEN** the response SHALL include `cache_time` indicating the WIP snapshot timestamp
+
+#### Scenario: No QC-GATE lots in cache
+- **WHEN** no LOTs match the QC-GATE SPECNAME pattern
+- **THEN** the system SHALL return an empty `stations` array with `cache_time`
+
+### Requirement: QC-GATE stations SHALL be ordered by spec sequence
+The system SHALL order QC-GATE stations according to the manufacturing flow sequence from `DW_MES_SPEC_WORKCENTER_V`.
+
+#### Scenario: Station ordering
+- **WHEN** the API returns multiple QC-GATE stations
+- **THEN** the stations SHALL be sorted by `SPEC_ORDER` from `DW_MES_SPEC_WORKCENTER_V` where `SPEC` matches the SPECNAME
+
+#### Scenario: Station not found in spec dimension table
+- **WHEN** a QC-GATE SPECNAME is not found in `DW_MES_SPEC_WORKCENTER_V`
+- **THEN** the station SHALL appear at the end of the list with a high default sort order
+
+### Requirement: QC-GATE report page SHALL display stacked bar chart
+The page SHALL display a stacked bar chart showing LOT counts per QC-GATE station, grouped by wait time bucket.
+
+#### Scenario: Bar chart rendering
+- **WHEN** the page loads and data is available
+- **THEN** the X-axis SHALL show QC-GATE station names
+- **THEN** the Y-axis SHALL show LOT counts
+- **THEN** each bar SHALL be stacked with four color-coded segments: <6hr (green), 6-12hr (yellow), 12-24hr (orange), >24hr (red)
+
+#### Scenario: Empty state
+- **WHEN** no QC-GATE LOTs exist
+- **THEN** the chart area SHALL display a "目前無 QC-GATE LOT" message
+
+### Requirement: QC-GATE report page SHALL display filterable LOT table
+The page SHALL display a table listing individual LOTs, with click-to-filter interaction from the bar chart.
+
+#### Scenario: Default table display
+- **WHEN** the page loads
