feat(query-tool): rewrite frontend with ECharts tree, multi-select, and modular composables

Replace the monolithic useQueryToolData composable and nested Vue component tree with a modular architecture: useLotResolve, useLotLineage, useLotDetail, and useEquipmentQuery. Introduce ECharts TreeChart (LR orthogonal layout) for lot lineage visualization with multi-select support, subtree expansion, zoom/pan, and serial number normalization. Add unified LineageEngine backend with split descendant traversal and leaf serial number queries. Archive the query-tool-rewrite openspec change and sync delta specs to main.

+# Reject 歷史績效表設計說明
+
+## 目標
+使用 `DW_MES_LOTREJECTHISTORY` 為主，輔以其他維度表，建立可直接用於報表的 `reject` 歷史績效表（按日彙總），解決原始資料直接查詢時的績效與一致性問題。
+
+## 使用資料表
+- `DWH.DW_MES_LOTREJECTHISTORY`: 不良/報廢事實表（主來源）
+- `DWH.DW_MES_CONTAINER`: 補齊 `PJ_TYPE`、`PRODUCTLINENAME`、`MFGORDERNAME`
+- `DWH.DW_MES_SPEC_WORKCENTER_V`: 對應 `WORKCENTER_GROUP` 與排序欄位
+
+## 資料評估重點（2026-02-13，近 30 天樣本）
+- `DW_MES_LOTREJECTHISTORY` 共 `230,074` 筆；`HISTORYMAINLINEID` 僅 `75,683` 個。
+- `HISTORYMAINLINEID` 多筆情況明顯（`30,784` 個主事件，平均每主事件 `6.02` 筆），代表同主事件會拆成多個 `LOSSREASONNAME`。
+- 若直接加總 `MOVEINQTY`，分母會被重複計算。近 30 天樣本中：
+  - `NAIVE_MOVEIN = 44,836,693,831`
+  - `DEDUP_MOVEIN = 35,658,750,247`
+  - 膨脹比 `1.2574`（約高估 25.74%）
+- 指標定義依業務規則分開處理：
+  - `REJECT_TOTAL_QTY = REJECTQTY + STANDBYQTY + QTYTOPROCESS + INPROCESSQTY + PROCESSEDQTY`（扣帳報廢）
+  - `DEFECT_QTY = DEFECTQTY`（不扣帳報廢）
+- `DW_MES_SPEC_WORKCENTER_V` 若直接以 `WORK_CENTER` join 會放大筆數；需先彙整為唯一 `WORK_CENTER -> GROUP/SEQUENCE` 對照表再 join。
+
+## 績效表欄位與計算邏輯
+- 粒度：`日 + 工站群組 + 工站 + 站點規格 + 設備 + 產品維度 + 不良原因`
+- 核心指標：
+  - `REJECT_EVENT_ROWS`: 原始 reject 紀錄筆數
+  - `AFFECTED_LOT_COUNT`: 受影響 lot 數（distinct `CONTAINERID`）
+  - `MOVEIN_QTY`: 以 `HISTORYMAINLINEID` 去重後的投入量
+  - `REJECT_QTY`: 原始 `REJECTQTY` 加總（五欄之一）
+  - `REJECT_TOTAL_QTY`: 五個 reject 相關欄位加總（扣帳報廢）
+  - `DEFECT_QTY`: `DEFECTQTY` 加總（不扣帳報廢）
+  - `REJECT_RATE_PCT = REJECT_TOTAL_QTY / MOVEIN_QTY * 100`
+  - `DEFECT_RATE_PCT = DEFECT_QTY / MOVEIN_QTY * 100`
+  - `REJECT_SHARE_PCT = REJECT_TOTAL_QTY / (REJECT_TOTAL_QTY + DEFECT_QTY) * 100`
+
+## 交付檔案
+- 建表 + 刷新 SQL：`docs/reject_history_performance.sql`
+- 可被應用層直接載入的查詢 SQL：`src/mes_dashboard/sql/reject_history/performance_daily.sql`
+
+## 建議排程
+- 每日跑前一日增量：
+  - `:start_date = TRUNC(SYSDATE - 1)`
+  - `:end_date = TRUNC(SYSDATE - 1)`
+- 每月第一天補跑前 31 天，避免補數漏失。

+## Context
+
+The query-tool ("批次追蹤工具") is the primary batch tracing page used by production engineers to trace LOT lineage, inspect production history, and query equipment records. The current implementation is a monolithic `App.vue` (343L) + `useQueryToolData.js` (448L) with custom CSS, no component decomposition, and flat `<ul>` lineage display.
+
+The backend is fully ready:
+- `/api/query-tool/resolve` — LOT/Serial/WO resolution (max 50/50/10 inputs)
+- `/api/trace/lineage` — LineageEngine genealogy (ancestors + merges, rate limit 10/60s)
+- `/api/query-tool/lot-history` — production history with workcenter filter
+- `/api/query-tool/lot-associations` — materials/rejects/holds/splits/jobs
+- `/api/query-tool/equipment-period` — 5 query types (status_hours, lots, materials, rejects, jobs)
+- `/api/query-tool/export-csv` — 11 export types
+
+All backend endpoints remain unchanged. This is a pure frontend rewrite.
+
+Existing design patterns from other modernized pages:
+- Tailwind tokens: `brand-500`, `surface-card`, `stroke-soft`, `state-*`, `rounded-card`, `shadow-panel`
+- Shared components: `SectionCard`, `FilterToolbar`, `StatusBadge`, `PaginationControl`, `TraceProgressBar`
+- Shared composables: `useAutoRefresh`, `usePaginationState`, `useQueryState`, `useTraceProgress`
+- Font: Noto Sans TC / Microsoft JhengHei, body 13px
+
+## Goals / Non-Goals
+
+**Goals:**
+- Complete frontend rewrite of query-tool with Tailwind + component architecture
+- Tab-based layout: LOT tracing / Equipment query as independent tabs
+- Lineage decomposition tree with auto-fire + concurrency control + growth animation
+- Production timeline (Gantt-style) for both LOT history and equipment activity
+- Left-right master-detail for LOT tab (tree left, detail right)
+- Per-sub-tab CSV export
+- URL state persistence for tab, filters, and selected lot
+
+**Non-Goals:**
+- No backend API changes
+- No new npm dependencies (timeline is SVG/CSS, no chart library)
+- No changes to other pages (mid-section-defect uses its own TraceProgressBar integration)
+- No real-time/WebSocket features
+- No pagination on lineage or association tables (datasets are bounded by single-lot scope)
+
+## Decisions
+
+### D1: Tab-based separation of LOT and Equipment
+
+LOT tracing and equipment query are completely unrelated workflows. Users never need both simultaneously.
+
+**Decision**: Two top-level tabs with independent state. Tab state tracked via URL `?tab=lot|equipment`.
+
+**Alternative considered**: Keep as single scrollable page → rejected because the page becomes too long and users lose context scrolling between sections.
+
+### D2: Lineage tree as left navigation panel
+
+The lineage decomposition tree serves dual purpose: it IS the lot list AND the genealogy visualization.
+
+**Decision**: After resolve, root nodes (resolved lots) appear in the left panel. Each root can expand to show ancestors. Clicking any node (root or ancestor) selects it and loads detail in the right panel.
+
+**Rationale**: Eliminates the need for a separate "lot list" component. The tree naturally represents the resolve results + their relationships.
+
+**Layout**: Left panel ~300px fixed width, right panel fills remaining space. Below 1024px, stack vertically.
+
+### D3: Auto-fire lineage with concurrency limiter
+
+After resolve, lineage is the primary value — users want to see the genealogy immediately.
+
+**Decision**: Auto-fire `POST /api/trace/lineage` for each resolved lot with `concurrency=3`. Results render progressively as they arrive, animating tree growth.
+
+**Concurrency calculation**: Rate limit is 10/60s. With concurrency=3 and avg ~1.5s per call, we'll sustain ~2 calls/s, comfortably below the limit. For 50 lots, all lineage completes in ~25s with continuous tree growth.
+
+**Alternative considered**: On-demand only (click to expand) → rejected because the user explicitly wants to see the full picture immediately. The auto-fire + animation creates an engaging "tree growing" experience.
+
+**Cache**: Per-lot lineage cached in a reactive Map. Cache cleared on new resolve.
+
+### D4: Progressive tree growth animation
+
+**Decision**: Use Vue `<TransitionGroup>` with CSS transforms:
+- Root nodes: `opacity 0→1` (fade-in on resolve)
+- Branch nodes: `translateX(-16px)→0` + `opacity 0→1` (slide-in from left)
+- Sibling stagger: 30-50ms delay between consecutive siblings
+- Level 2+ nodes animate when their parent's lineage data arrives (same animation)
+
+**Implementation**: `LineageNode.vue` is a recursive component. Each node wraps its children in `<TransitionGroup>`. When the reactive lineage cache updates for a lot, Vue reactivity triggers child insertion, which triggers the enter transition.
+
+### D5: TimelineChart as shared SVG component
+
+Both LOT production timeline and equipment timeline need the same Gantt-style visualization.
+
+**Decision**: Create a `TimelineChart.vue` component that accepts:
+```
+Props:
+  tracks: Array<{ id, label, layers: Array<{ bars: Array<{start, end, type}> }> }>
+  events: Array<{ trackId, time, type, label, detail }>
+  timeRange: { start: Date, end: Date }
+  colorMap: Record<string, string>
+```
+
+**Rendering**: Pure SVG with:
+- Sticky left labels (CSS `position: sticky`)
+- Horizontal time axis with auto-scaled ticks (hours or days)
+- Multi-layer bars per track (background layer + foreground layer)
+- Event markers as SVG icons (diamond shape) with hover tooltips
+- Horizontal scroll container for wide timelines
+
+**No external deps**: SVG + CSS only. Time calculations use native Date. No D3, no ECharts.
+
+### D6: LOT Timeline data mapping
+
+LOT production history records have TRACKINTIMESTAMP and TRACKOUTTIMESTAMP per station.
+
+**Decision**: Map lot-history rows to TimelineChart tracks:
+- Each unique WORKCENTERNAME = one track
+- Each row = one bar (track-in to track-out, colored by workcenter group)
+- Hold events from lot-holds = event markers
+- Workcenter filter shows/hides tracks
+
+### D7: Equipment Timeline multi-source composition
+
+Equipment timeline overlays three data sources on a single track per equipment.
+
+**Decision**: Fetch `status_hours`, `lots`, and `jobs` data, then compose:
+- Layer 0 (background): Status bars (PRD=green, SBY=amber, UDT=red, SDT=blue-gray)
+- Layer 1 (foreground): Lot processing bars (track-in to track-out)
+- Events: Maintenance job markers (JOBID + CAUSECODENAME as label)
+
+**Note**: This requires 3 API calls per equipment tab query. They can fire in parallel since they're independent.
+
+### D8: Composable architecture
+
+Split the monolithic `useQueryToolData.js` (448L) into focused composables:
+
+| Composable | Responsibility | State |
+|-----------|---------------|-------|
+| `useLotResolve` | Input parsing, resolve API, URL state for resolve params | `resolvedLots`, `notFound`, `loading.resolving` |
+| `useLotLineage` | Lineage auto-fire, concurrency limiter, tree expand/collapse state, cache | `lineageMap`, `expandedNodes`, `loadingSet` |
+| `useLotDetail` | Per-lot history + associations, sub-tab active state, sub-tab cache | `activeSubTab`, `historyRows`, `associationRows`, caches |
+| `useEquipmentQuery` | Equipment list, date range, 4 query types, sub-tab state | `equipment.*`, `activeSubTab`, query results |
+
+Each composable manages its own loading/error state. No global error banner — errors display contextually within each section.
+
+### D9: Delete legacy files
+
+- `frontend/src/query-tool/main.js` → rewrite to minimal Vite entry (3-5 lines: import App, createApp, mount)
+- `frontend/src/query-tool/style.css` → delete entirely, all styling via Tailwind
+
+## Risks / Trade-offs
+
+**[100+ lots from work order → tree overwhelm]** → The lineage tree with 100+ root nodes could be visually overwhelming. Mitigation: Virtual scroll or "show first 20, load more" pattern for the tree panel if needed. Start without it and evaluate.
+
+**[Lineage auto-fire rate limit pressure]** → With 50 lots and concurrency=3, we'll make ~50 requests within ~25s. Rate limit is 10/60s which means we'd hit the limit at lot #10. Mitigation: The concurrency limiter must respect 429 responses and back off. If rate limited, pause and retry after `Retry-After` header. Alternatively, batch multiple container_ids per lineage call (backend already supports arrays).
+
+**[Timeline SVG performance with large datasets]** → Equipment timeline spanning 90 days with 20 equipment could generate thousands of SVG elements. Mitigation: Aggregate status bars at coarse granularity for wide ranges, detailed view for narrow ranges. Start with naive rendering and optimize if needed.
+
+**[Left panel width on narrow screens]** → 300px fixed width may be too wide on 1024-1280px screens. Mitigation: Make the left panel collapsible/resizable, or use a narrower default (240px) with a expand-on-hover pattern.
+
+## Resolved Questions
+
+- **Q1 (Resolved)**: Lineage API calls SHALL be per-lot independent (not batched). This preserves the progressive tree growth animation — each API response triggers a visual branch expansion. With concurrency=3 and 429 backoff, this stays within rate limits while providing engaging UX.
+- **Q2 (Resolved)**: Equipment timeline SHALL use the `DW_MES_RESOURCESTATUS_SHIFT` aggregate table (8h shift granularity). This avoids querying raw status change events which are voluminous and not readily available via existing API. The 8h blocks are sufficient for timeline overview; users needing finer granularity can inspect the lots/jobs sub-tabs for exact timestamps.

+## Why
+
+The query-tool page ("批次追蹤工具") is the last major page still running as a monolithic Vue SFC with custom CSS. Its 343-line App.vue and 448-line useQueryToolData composable pack all three unrelated features (LOT tracing, LOT detail, equipment period query) into one vertical scroll with no component decomposition. Lineage visualization is a flat `<ul><li>` list, production history is a static table with no timeline view, and there is no progressive loading animation despite the staged trace API being available. The page needs a complete frontend rewrite to match the Tailwind + component-based architecture used by all other modernized pages, while significantly improving the tracing UX.
+
+## What Changes
+
+- **Complete rewrite** of `frontend/src/query-tool/` — new component tree, composables, and Tailwind-only styling (no style.css)
+- **Tab-based layout**: Split LOT tracing and equipment query into independent top-level tabs
+- **Lineage decomposition tree**: Replace flat ancestor list with an interactive tree that "grows" progressively as lineage API calls return (limited concurrency, animated node insertion)
+- **Left-right master-detail layout**: Lineage tree as left navigation panel, LOT detail (sub-tabs) on right
+- **Production timeline** (shared `TimelineChart.vue`): Gantt-style visualization for both LOT production history (stations over time) and equipment activity (lots + maintenance + status)
+- **Equipment tab redesign**: Replace 5 generic query types with 4 focused sub-tabs — production lots, maintenance records (with cause/repair/symptom codes), scrap records, and equipment timeline
+- **Auto-fire lineage with concurrency control**: After resolve, lineage API calls fire automatically with concurrency=3, tree grows as results arrive
+- **Per-sub-tab CSV export**: Each detail sub-tab has its own export button instead of one shared context-aware export
+- **Delete legacy `main.js`**: The 448-line vanilla JS module in query-tool is dead code superseded by the Vue SFC
+
+## Capabilities
+
+### New Capabilities
+- `query-tool-lot-trace`: LOT tracing tab — query bar, lineage decomposition tree with progressive growth animation, left-right master-detail layout, LOT detail sub-tabs (history with workcenter filter + timeline, materials, rejects, holds, splits, jobs), per-tab CSV export
+- `query-tool-equipment`: Equipment query tab — equipment/date selection, 4 sub-tabs (production lots, maintenance records, scrap records, equipment timeline), per-tab CSV export
+- `timeline-chart`: Shared Gantt-style timeline visualization component — horizontal time axis, configurable tracks with colored bars, event markers, tooltips, used by both LOT and equipment views
+
+### Modified Capabilities
+- `progressive-trace-ux`: Lineage tree now auto-fires with concurrency-limited parallel requests and animated progressive rendering (expanding the on-demand spec to support auto-fire mode)
+
+## Impact
+
+- **Frontend**: Complete rewrite of `frontend/src/query-tool/` (App.vue, composables, new component tree of ~15 files)
+- **Backend**: Zero changes — all existing `/api/query-tool/*` and `/api/trace/*` endpoints remain unchanged
+- **Shared UI**: New `TimelineChart.vue` component may live in `shared-ui/` or query-tool local components
+- **Dead code**: `frontend/src/query-tool/main.js` (448L) and `frontend/src/query-tool/style.css` deleted
+- **Dependencies**: No new npm packages — timeline rendered with SVG/CSS, tree with recursive Vue components + TransitionGroup

+## Why
+
+目前專案只有在 `query-tool` 的設備子頁籤提供報廢相關查詢，缺少一個可長期追蹤「報廢歷史」的專用報表頁。隨著既有架構已完成 portal-shell、route contract、Vite 多頁治理，現在適合用同一套架構新增 `報廢歷史查詢`，避免再引入獨立樣式或旁路流程。
+
+## What Changes
+
+- 新增 `報廢歷史查詢` 頁面路由 `/reject-history`，採用既有 pure Vite + portal-shell native route 模式。
+- 新增後端 `reject-history` API 群組（摘要、趨勢、原因 Pareto、明細、匯出），提供前端報表所需資料。
+- 新增 `reject-history` service + SQL 模組，統一計算：
+  - 扣帳報廢：`REJECT_TOTAL_QTY = REJECTQTY + STANDBYQTY + QTYTOPROCESS + INPROCESSQTY + PROCESSEDQTY`
+  - 不扣帳報廢：`DEFECT_QTY = DEFECTQTY`
+- 將新頁面納入既有導航與契約治理（page registry、drawer、routeContracts、nativeModuleRegistry、shell coverage）。
+- 補齊對應測試（API/服務單元測試、route contract 治理測試、必要的頁面整合測試）。
+
+## Capabilities
+
+### New Capabilities
+- `reject-history-page`: 新增報廢歷史查詢頁面，提供篩選、KPI、趨勢、原因分析與明細查詢/匯出。
+- `reject-history-api`: 新增報廢歷史 API 能力與資料聚合邏輯，定義扣帳報廢與不扣帳報廢的並列指標語義。
+
+### Modified Capabilities
+- `unified-shell-route-coverage`: 新增 `/reject-history` 後，路由契約清單與前後端契約對照規則需同步更新。
+- `vue-vite-page-architecture`: 新頁面需納入 Vite entry/output 與 Flask static HTML 服務規範，保持既有純 Vite 頁治理一致性。
+
+## Impact
+
+- 前端：
+  - 新增 `frontend/src/reject-history/`（`App.vue`、`main.js`/`index.html`、components、composables、style）
+  - 更新 `frontend/src/portal-shell/nativeModuleRegistry.js`
+  - 更新 `frontend/src/portal-shell/routeContracts.js`
+  - 更新 `frontend/vite.config.js`
+- 後端：
+  - 新增 `src/mes_dashboard/routes/reject_history_routes.py`
+  - 新增 `src/mes_dashboard/services/reject_history_service.py`
+  - 新增 `src/mes_dashboard/sql/reject_history/*.sql`
+  - 更新 `src/mes_dashboard/routes/__init__.py`
+  - 更新 `src/mes_dashboard/app.py`（`/reject-history` 靜態頁 route）
+- 導航/治理：
+  - 更新 `data/page_status.json`（drawer 與頁面可見性）
+  - 更新 shell route contract 對應治理資產與測試基準
+- 測試：
+  - 新增 `tests/test_reject_history_service.py`
+  - 新增 `tests/test_reject_history_routes.py`
+  - 補充 route coverage / contract parity / e2e smoke
+- 依賴：
+  - 不新增第三方套件，沿用現有 Flask + Vue + Vite + SQLLoader + QueryBuilder 架構
