- Simplify parseApkFilename to use version delimiter split
- Update tests to match new data structure with rawEnvironment
- Remove unnecessary test cases and assertions

+# APK Parsing Fix Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Fix APK filename parsing to use version number as delimiter and support configurable environment tabs.
+
+**Architecture:** Parse APK filenames by splitting on `_<version>` to extract prefix. If prefix has no underscore → product. If prefix has underscore → extract environment from last segment. Match against configurable tabs (env var), unmatched → other.
+
+**Tech Stack:** Next.js, TypeScript, environment variables
+
+---
+
+### Task 1: Add APK_TABS Environment Variable
+
+**Files:**
+- Modify: `lib/constants.ts`
+
+**Step 1: Add APK_TABS constant**
+
+```typescript
+// Add to lib/constants.ts
+export const APK_TABS = (process.env.APK_TABS || 'dev,sandbox')
+  .split(',')
+  .map(t => t.trim())
+  .filter(Boolean);
+```
+
+**Step 2: Verify no build errors**
+
+Run: `npm run build`
+Expected: Build succeeds
+
+**Step 3: Commit**
+
+```bash
+git add lib/constants.ts
+git commit -m "feat: add APK_TABS environment variable for configurable tabs"
+```
+
+---
+
+### Task 2: Rewrite APK Parser Logic
+
+**Files:**
+- Modify: `lib/apk-parser.ts`
+- Modify: `lib/__tests__/apk-parser.test.ts`
+
+**Step 1: Write failing tests for new parsing logic**
+
+Replace `lib/__tests__/apk-parser.test.ts`:
+
+```typescript
+import { parseApkFilename, detectEnvironment, getApkTabs } from '../apk-parser';
+
+describe('parseApkFilename', () => {
+  it('should parse product APK (no environment)', () => {

+
+  it('should handle invalid format without commit', () => {

+    expect(result.environment).toBe('other');
+    expect(result.commit).toBeNull();
+    expect(result.isValid).toBe(false);
+  });
+});
+
+describe('detectEnvironment', () => {
+  it('should detect product when no underscore in prefix', () => {
+    expect(detectEnvironment('ft', ['dev', 'sandbox'])).toBe('product');
+  });
+
+  it('should detect configured environment', () => {
+    expect(detectEnvironment('ft_dev', ['dev', 'sandbox'])).toBe('dev');
+    expect(detectEnvironment('ft_sandbox', ['dev', 'sandbox'])).toBe('sandbox');

+  });
+
+  it('should return other for empty prefix', () => {
+    expect(detectEnvironment('', ['dev', 'sandbox'])).toBe('other');
+  });
+});
+```
+
+**Step 2: Run tests to verify they fail**
+
+Run: `npm test -- lib/__tests__/apk-parser.test.ts`
+Expected: Tests fail with missing `getApkTabs` and wrong behavior
+
+**Step 3: Implement new parsing logic**
+
+Replace `lib/apk-parser.ts`:
+
+```typescript
+import { APK_TABS } from './constants';
+
+export type ApkEnvironment = 'product' | 'dev' | 'sandbox' | 'other';
+
+export interface ParsedApkMetadata {
+  environment: ApkEnvironment;
+  commit: string | null;
+  isValid: boolean;
+}
+
+export function getApkTabs(): string[] {
+  return APK_TABS;
+}
+
+export function detectEnvironment(prefix: string, configuredTabs: string[]): ApkEnvironment {
+  // Empty prefix → other
+  if (!prefix) {
+    return 'other';
+  }
+
+  // No underscore means product (e.g., "ft")
+  if (!prefix.includes('_')) {
+    return 'product';
+  }
+
+  // Extract environment from last segment after underscore
+  const lastUnderscoreIndex = prefix.lastIndexOf('_');
+  const env = prefix.substring(lastUnderscoreIndex + 1);
+
+  // Check if environment is configured
+  if (configuredTabs.includes(env)) {
+    return env as ApkEnvironment;
+  }
+
+  return 'other';
+}
+
+export function parseApkFilename(filename: string, version: string): ParsedApkMetadata {
+  // Use version as delimiter (with leading underscore)
+  const delimiter = `_${version}`;
+  const delimiterIndex = filename.indexOf(delimiter);
+
+  let prefix: string;
+  if (delimiterIndex > 0) {
+    prefix = filename.substring(0, delimiterIndex);
+  } else {
+    // Fallback: can't find version delimiter
+    prefix = '';
+  }
+
+  const environment = detectEnvironment(prefix, APK_TABS);
+
+  // Extract commit ID
+  const commitMatch = filename.match(/([a-f0-9]{7,})\.apk$/);
+  const commit = commitMatch ? commitMatch[1] : null;
+
+  return {
+    environment,
+    commit,
+    isValid: commit !== null,
+  };
+}
+```
+
+**Step 4: Run tests to verify they pass**
+
+Run: `npm test -- lib/__tests__/apk-parser.test.ts`
+Expected: All tests pass
+
+**Step 5: Commit**
+
+```bash
+git add lib/apk-parser.ts lib/__tests__/apk-parser.test.ts
+git commit -m "feat: rewrite APK parser to use version as delimiter"
+```
+
+---
+
+### Task 3: Update API Route to Pass Version
+
+**Files:**
+- Modify: `app/api/apks/route.ts`
+- Modify: `app/api/__tests__/apks.test.ts`
+
+**Step 1: Check existing API test**
+
+Read: `app/api/__tests__/apks.test.ts`
+
+**Step 2: Update API route to pass version**
+
+Modify `app/api/apks/route.ts` line 22:
+
+```typescript
+// Change from:
+const parsed = parseApkFilename(apk.name);
+// To:
+const parsed = parseApkFilename(apk.name, version);
+```
+
+**Step 3: Verify build succeeds**
+
+Run: `npm run build`
+Expected: Build succeeds
+
+**Step 4: Commit**
+
+```bash
+git add app/api/apks/route.ts
+git commit -m "feat: pass version parameter to APK parser"
+```
+
+---
+
+### Task 4: Update ApkList to Use Configured Tabs
+
+**Files:**
+- Modify: `lib/constants.ts`
+- Modify: `app/download/ApkList.tsx`
+- Add: `app/api/config/route.ts`
+
+**Step 1: Create config API endpoint**
+
+Create `app/api/config/route.ts`:
+
+```typescript
+import { NextResponse } from 'next/server';
+import { APK_TABS } from '@/lib/constants';
+
+export async function GET() {
+  return NextResponse.json({
+    tabs: APK_TABS,
+  });
+}
+```
+
+**Step 2: Update ApkList to fetch and use configured tabs**
+
+Modify `app/download/ApkList.tsx`:
+
+```typescript
+'use client';
+
+import { useState, useEffect } from 'react';
+import useSWR from 'swr';
+import { type ApkEnvironment } from '@/lib/apk-parser';

+# Download Page 可读性优化设计
+
+## 概述
+
+提高 `download` page 的可读性，解决两个问题：
+1. SearchForm 内填写/选择的文字颜色过浅
+2. ApkList 的 commit id 列需要显示环境标签
+
+## 修改项
+
+### 1. SearchForm 文字颜色修复
+
+**问题**: 下拉框选中后的文字和输入框内的文字颜色太浅，用户看不清。
+
+**解决方案**: 为 `select` 和 `input` 元素添加 `text-gray-900` 类。
+
+**修改文件**: `app/download/SearchForm.tsx`
+
+**改动点**:
+- 项目下拉框 (line ~61): 添加 `text-gray-900`
+- 版本下拉框 (line ~86): 添加 `text-gray-900`
+- Commit ID 输入框 (line ~112): 添加 `text-gray-900`
+
+### 2. ApkList commit id 列显示环境标签
+
+**问题**: 当前 commit id 列只显示 commit hash，无法直观看出 APK 的环境。
+
+**解决方案**: 在 commit id 后面添加彩色环境标签。
+
+**修改文件**:
+- `app/download/ApkTable.tsx` - 接收并显示 environment
+- `app/download/ApkList.tsx` - 传递 environment 属性给 ApkTable
+
+**标签样式**:
+| 环境 | 样式 |
+|------|------|
+| product | 蓝色背景 `bg-blue-100 text-blue-800` |
+| dev | 绿色背景 `bg-green-100 text-green-800` |
+| sandbox | 绿色背景 `bg-green-100 text-green-800` |
+| other | 灰色背景 `bg-gray-100 text-gray-800` |
+
+**显示效果示例**:
+```
+abc1234 [product]
+def5678 [dev]
+xyz9012 [other]
+```
+
+## 实现步骤
+
+1. 修改 `SearchForm.tsx` - 为 3 个表单控件添加 `text-gray-900`
+2. 修改 `ApkList.tsx` - 确保 Apk interface 包含 environment 并传递给 ApkTable
+3. 修改 `ApkTable.tsx` - 更新 Apk interface，在 commit 列显示环境标签

+# Download Page 可读性优化 实现计划
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** 提高 download page 的可读性：修复 SearchForm 文字颜色、在 commit id 列显示环境标签
+
+**Architecture:** 直接修改现有组件，为表单控件添加文字颜色类，为 ApkTable 添加环境标签显示
+
+**Tech Stack:** Next.js, React, Tailwind CSS, TypeScript
+
+---
+
+### Task 1: 修复 SearchForm 文字颜色
+
+**Files:**
+- Modify: `app/download/SearchForm.tsx:61,86,112`
+
+**Step 1: 为项目下拉框添加文字颜色**
+
+修改 `app/download/SearchForm.tsx` 第 61 行，为项目 select 添加 `text-gray-900`：
+
+```tsx
+className="w-full px-3 py-2 border border-gray-300 rounded-md focus:outline-none focus:ring-2 focus:ring-blue-500 text-gray-900"
+```
+
+**Step 2: 为版本下拉框添加文字颜色**
+
+修改第 86 行，为版本 select 添加 `text-gray-900`：
+
+```tsx
+className="w-full px-3 py-2 border border-gray-300 rounded-md focus:outline-none focus:ring-2 focus:ring-blue-500 disabled:bg-gray-100 disabled:cursor-not-allowed text-gray-900"
+```
+
+**Step 3: 为 Commit ID 输入框添加文字颜色**
+
+修改第 112 行，为 input 添加 `text-gray-900`：
+
+```tsx
+className="w-full px-3 py-2 border border-gray-300 rounded-md focus:outline-none focus:ring-2 focus:ring-blue-500 text-gray-900"
+```
+
+**Step 4: 验证修改**
+
+Run: `npm run build`
+Expected: Build succeeds without errors
+
+**Step 5: 提交**
+
+```bash
+git add app/download/SearchForm.tsx
+git commit -m "fix: improve SearchForm text visibility with darker color
+
+Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>"
+```
+
+---
+
+### Task 2: ApkTable 添加环境标签显示
+
+**Files:**
+- Modify: `app/download/ApkTable.tsx`
+
+**Step 1: 更新 Apk interface 添加 environment 字段**
+
+修改 `app/download/ApkTable.tsx` 的 Apk interface (约第 5-11 行)：
+
+```tsx
+import { formatFileSize, formatDateTime } from '@/lib/utils';
+import { type ApkEnvironment } from '@/lib/apk-parser';
+
+interface Apk {
+  name: string;
+  environment: ApkEnvironment;
+  commit: string | null;
+  size: number;
+  modifiedAt: string;
+  downloadUrl: string;
+}
+```
+
+**Step 2: 添加环境标签渲染辅助函数**
+
+在 interface 后、组件前添加：
+
+```tsx
+function getEnvironmentBadgeClass(env: ApkEnvironment): string {
+  switch (env) {
+    case 'product':
+      return 'bg-blue-100 text-blue-800';
+    case 'dev':
+    case 'sandbox':
+      return 'bg-green-100 text-green-800';
+    default:
+      return 'bg-gray-100 text-gray-800';
+  }
+}
+
+function formatEnvironment(env: ApkEnvironment): string {
+  return env;
+}
+```
+
+**Step 3: 修改 commit id 列显示环境标签**
+
+修改约第 48-52 行的 commit id 单元格：
+
+```tsx
+<td className="px-6 py-4 whitespace-nowrap">
+  <div className="flex items-center gap-2">
+    <span className="font-mono text-sm text-gray-900">
+      {apk.commit || '-'}
+    </span>
+    <span className={`px-2 py-0.5 text-xs font-medium rounded ${getEnvironmentBadgeClass(apk.environment)}`}>
+      {formatEnvironment(apk.environment)}
+    </span>
+  </div>
+</td>
+```
+
+**Step 4: 验证修改**
+
+Run: `npm run build`
+Expected: Build succeeds without errors
+
+**Step 5: 提交**
+
+```bash
+git add app/download/ApkTable.tsx
+git commit -m "feat: add environment badge to commit id column in ApkTable
+
+Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>"
+```
+
+---
+
+### Task 3: 验证 ApkList 传递 environment
+
+**Files:**
+- Verify: `app/download/ApkList.tsx`
+
+**Step 1: 检查 ApkList 是否已正确传递 environment**
+
+查看 `app/download/ApkList.tsx`：
+- Apk interface 已包含 `environment: ApkEnvironment` (第 12 行)
+- ApkList 传给 ApkTable 的 apks 来自 `groupedApks[activeTab]` (第 101 行)
+- 这些 apks 已包含 environment 字段
+
+**结论**: 无需修改，environment 已正确传递。
+
+**Step 2: 最终验证**
+
+Run: `npm run build && npm test`
+Expected: Build succeeds, all tests pass
+
+**Step 3: 最终提交（如有未提交的更改）**
+
+```bash
+git status
+# If clean, no action needed
+```
+
+---
+
+## 验收标准
+
+1. SearchForm 中选择项目/版本后，文字清晰可见（深灰色）
+2. ApkTable 的 commit id 列显示环境标签，如 `abc1234 [product]`
+3. 不同环境有不同颜色：product=蓝色, dev/sandbox=绿色, other=灰色
+4. `npm run build` 成功
+5. `npm test` 全部通过
