+# Quick Task 260425-w2i: 区域转移概率统计
+
+## Plan
+
+1. **Model** — Add `getZoneTransition($periods)` method to `app\admin\model\History`
+   - Query latest `$periods` periods ordered by openTime ASC
+   - Divide numbers 1-49 into 5 zones: 1-10, 11-20, 21-30, 31-40, 41-49
+   - For each consecutive pair of periods, record (current_zone → next_zone)
+   - Return: `{zones: ['1-10','11-20','21-30','31-40','41-49'], matrix: [[count...]], probabilities: [[prob...]], total_transitions: N}`
+
+2. **Controller** — Add `zoneTransition()` method to `app\admin\controller\History`
+   - Accept `periods` param (default 100, range 10-500)
+   - Add to `$noNeedRight` list
+   - Call model method, return JSON response
+
+3. **Dashboard** — Include `zoneTransition` in `getDashboardData()` response
+
+4. **Frontend JS** — Add zone transition heatmap/table in `public/assets/js/backend/dashboard.js`
+   - Render as a 5×5 matrix table with color-coded cells showing count and percentage
+   - Append below existing heatmap section

+# Quick Task 260425-w2i Summary
+
+## Description
+在控制台页面新增区域转移概率统计功能：将1-49数字分为5个区域(每10个数一个区域)，统计每一区域出现特码后下一期出现特码的区域概率。
+
+## Changes
+- `application/admin/model/History.php` — 新增 `getZoneTransition($periods)` 方法，返回5×5转移矩阵和概率
+- `application/admin/controller/History.php` — 新增 `zoneTransition()` AJAX接口，加入 `$noNeedRight`
+- `application/admin/model/History.php` — `getDashboardData()` 增加 `zonetransition` 字段
+- `public/assets/js/backend/dashboard.js` — 渲染区域转移概率彩色表格
+
+## Commits
+- `28415a1` feat(dashboard): 添加区域转移概率统计功能
+- `6df33a6` docs(state): 记录区域转移概率统计 quick task 完成
