fix: download timeout + file validation + source indicator + stale APK

Root cause of "install doesn't update": gradle cached old APK, release
uploaded stale version. Fixes:
- Dedicated download OkHttpClient with 120s readTimeout (was 30s)
- 64KB buffer (was 8KB) for faster large-file download
- Post-download file size validation (Content-Length / release declared)
- Reject files < 1MB (likely HTML error pages)
- downloadSource StateFlow shows "Gitea" or "GitHub" during download
- UpdateDialog shows "正在下载更新…（来自 Gitea）"
- version 1.9.2 -> 1.9.3 (code 31 -> 32)

 # GotMsg ·有消息
 
-把安卓手机上的通知（短信、验证码、电话、微信、QQ、Telegram）实时转发到 iOS / Android / 鸿蒙等接收端。
+把安卓手机上的通知（短信、验证码、电话“有电话进来这个通知，不是电话呼叫转移”、微信、QQ、Telegram 等）实时转发到 iOS / Android / 鸿蒙等接收端。iOS 可通过 [Bark](https://github.com/Finb/Bark) 推送到 iPhone / iPad；Android 可用 ntfy；鸿蒙可用 Meow。在 iOS 上点击通知，还能一键跳转到对应的 App。
 
 适用于把安卓备机的消息同步到 iPhone 或其他安卓 / 鸿蒙手机，不漏验证码、不漏重要聊天。
 
 ![GotMsg 设置页](screenshots/overview.png)
 
----
+## 主要功能
 
-## 一、五分钟上手
+- **系统级通知监听**：接入 Android 通知监听服务，覆盖所有发出通知的 App。
+- **多通道推送**：支持 Bark、ntfy、Meow、电邮和短信兜底；每个通道可保存多个目标，勾选参与转发，并支持“发通一条就停”或全部广播。
+- **验证码自动提取**：自动识别通知中的验证码，收到即复制，也可点击复制。
+- **通知优化**：
+  - 广告关键词过滤（内置 + 自定义）
+  - 持续性通知过滤（音乐、下载、通话等 ongoing）
+  - 内容脱敏与去重
+  - 微信 / QQ / Telegram 专项优化（发送者作标题、按会话分组、重要消息提级、跳转 iOS 对应 App）
+- **应用级规则**：黑名单 / 白名单两种模式，可按 App 单独控制是否转发。
+- **失败自动重试**：发送失败的通知进入待重发队列，由 WorkManager 定期重试，也可手动触发。
+- **本地日志**：保留最近 300 条处理记录，方便排查为什么某条通知被过滤或发送失败。
+- **电话来电通知**：通过轮询 `getCallState()` 实时感知来电和未接来电（绕过 MIUI 对系统电话通知的限制，需授予"电话"权限）。
+- **断网短信兜底**：无网络时自动把验证码、来电用短信发到 iPhone。
+  - 自动识别运营商（移动/联通/电信/广电），发免费查询短信拿套餐内短信余量
+  - 余额 ≤5 条自动停用，下次打开 App 提醒
+  - 每 5 分钟最多发 1 条，避免刷屏
+  - 自动解析失败时回退手动额度计数
+- **应用内更新**：每天自动检查 GitHub 新版本，发现新版后一键下载并通过系统安装器升级，无需手动去网页下载。
+
+## 快速开始
 
 ### 1. 安装
-从 [Releases](../../releases) 下载最新 APK，安装到安卓手机（需 Android 14 / API 34+）。
 
-### 2. 选一个推送通道
-推荐三选一：
+从 [Releases](../../releases) 下载最新 APK，安装到安卓手机（需 Android 14 / API 34 及以上）。
 
-| 接收设备 | 推荐通道 | 难度 |
-|---|---|---|
-| iPhone / iPad | **Bark** | ⭐ 最简单 |
-| 安卓手机 | **ntfy** | ⭐ 推荐开源 |
-| 鸿蒙手机 | **Meow** | 鸿蒙专属 |
+### 2. 配置 Bark
 
-打开 GotMsg -> 「设置」-> 选对应通道 -> 点右上角 **i** 按钮 -> 按弹窗步骤配 -> 点该行「发送」测试。
+1. 在 iOS 上安装 [Bark](https://apps.apple.com/us/app/bark-customed-push/id1613210986)。
+2. 打开 Bark，复制你的专属推送地址，形如 `https://api.day.app/你的Key`。
+3. 在 GotMsg 的「设置」中添加服务器：
+   - 名称：随意，例如「我的 iPhone」
+   - 服务器地址：`https://api.day.app`（自建则填自建地址）
+   - Device Key：Bark 地址中的那段 Key
+
+如果接收端是 Android 或鸿蒙手机，也可以在「设置」里配置 ntfy 或 Meow；对应区块右上角有帮助按钮，按弹窗步骤填写服务器地址、Topic / Device Key 后点测试发送。
 
 ### 3. 授权通知监听
-首页会提示「需要授权通知监听」。点击「前往系统授权」，在系统的通知访问设置中开启 GotMsg。
+
+打开 GotMsg，首页会提示「需要授权通知监听」。点击「前往系统授权」，在系统的通知访问设置中开启 GotMsg。
+
+> 授权是一次性的，卸载后重新安装需要再次授权。
 
 ### 4. 开启转发
-首页打开「通知转发」开关。安卓收到通知后按配置自动推送到各通道。
 
----
+回到首页，打开「通知转发」开关。此时安卓收到的通知就会按规则推送到 iOS。
 
-## 二、推送通道配置详解
+## 使用建议
 
-每条配置都可独立勾选/删除/排序/测试。点「添加」时建议每条都先「发送」测试一次。
-
-### 2.1 Bark（iOS / iPadOS）
-
-[Bark](https://github.com/Finb/Bark) 是 iOS 上最轻量的推送方案，复制地址即用，**推荐所有 iOS 用户首选**。
-
-**配置步骤**：
-1. iPhone / iPad 上安装 Bark，首次打开允许通知权限。
-2. 复制 Bark 首页的推送地址，形如 `https://api.day.app/你的Key`。
-3. GotMsg「设置 -> Bark 服务器 -> 添加」：
-   - **名称**：随意，例如「我的 iPhone」
-   - **服务器地址**：`https://api.day.app`（自建则填自建地址）
-   - **Device Key**：Bark 地址中 `/` 后面的那段
-4. 保存后点「发送」测试；iPhone 收到「GotMsg 测试」即成功。
-
-**为什么推荐 Bark**：iOS 上点击 Bark 通知体验最自然；通知会附带 GotMsg 回复链接，点击可打开回复页；Bark 服务器在中国大陆可直接访问。
-
-### 2.2 ntfy（Android / iOS / 网页）
-
-[ntfy](https://ntfy.sh) 是开源的 HTTP pub-sub 通知服务，**支持 Android、iOS 和网页端**，无需注册项目。
-
-**配置步骤**：
-1. 接收端安装 ntfy：
-   - Android：[Google Play](https://play.google.com/store/apps/details?id=io.heckel.ntfy) / [F-Droid](https://f-droid.org/en/packages/io.heckel.ntfy/) / [GitHub](https://github.com/binwiederhier/ntfy)
-   - iOS：[App Store](https://apps.apple.com/us/app/ntfy/id1625396347)
-2. 打开 ntfy -> 添加订阅。服务器填 `https://ntfy.sh`（或自建地址）；Topic 用一串**随机难猜的名字**（如 `gotmsg_a8f3d2`）。
-3. GotMsg「设置 -> ntfy 转发 -> 添加」：
-   - **服务器**：与接收端完全一致
-   - **Topic**：与接收端完全一致
-   - **Token**：仅自建服务且启用了鉴权时填
-4. 保存后点「发送」测试；接收端收到「GotMsg 测试」即成功。
-
-> **安全提示**：公共 topic 谁知道名字就能订阅或发送。Topic 名**不要用**手机号、姓名、邮箱等可猜信息。
-
-### 2.3 Meow（鸿蒙 / HarmonyOS）
-
-Meow 是鸿蒙手机的推送接收方案。GotMsg 按你填写的 Meow 接口地址和 Device Key 发出 HTTP 请求即可。
-
-**配置步骤**：
-1. 鸿蒙手机上安装 Meow，确认 Meow 自身能正常接收推送。
-2. 在 Meow 里找到**推送接口地址**和对应的 **Device Key / Token**。
-3. GotMsg「设置 -> Meow 转发 -> 添加」：
-   - **名称**：按鸿蒙设备填写（方便区分多台）
-   - **服务器地址**：Meow 给出的完整 API 地址
-   - **Device Key**：Meow 给你的设备 Key（**不是**鸿蒙锁屏密码、华为账号密码）
-4. 保存后点「发送」测试；鸿蒙手机收到「GotMsg 测试」即成功。
-
-> 失败排查：检查 Meow 接口地址是否完整、Key 是否复制完整、鸿蒙手机是否允许 Meow 通知。
-
-### 2.4 电邮转发
-
-通过 SMTP 把通知发到邮箱（**适合无手机接收的场景**，如仅在桌面/平板查看）。
-
-**配置步骤**：
-1. 准备一个 SMTP 邮箱（QQ/163/Gmail/Outlook 都可），**开启 SMTP 服务并生成授权码**（不是登录密码）。
-   - QQ：设置 -> 账户 -> POP3/IMAP/SMTP/Exchange/CardDAV/CalDAV服务 -> 开启 SMTP -> 生成授权码
-   - 163：设置 -> POP3/SMTP/IMAP -> 开启 SMTP -> 设置授权码
-   - Gmail：账户 -> 安全性 -> 两步验证 -> 应用专用密码
-2. GotMsg「设置 -> 电邮转发 -> 添加」：
-   - **名称**：随意
-   - **服务器（SMTP 主机）**：`smtp.qq.com` / `smtp.163.com` / `smtp.gmail.com` 等
-   - **端口**：`465`（推荐，隐式 SSL）或 `587`（STARTTLS）
-   - **账号**：完整邮箱地址
-   - **授权码 / 密码**：上一步生成的授权码
-   - **发件人**：通常与账号相同
-   - **收件人**：接收通知的目标邮箱
-3. 保存后点「发送」测试；收件人收到「GotMsg 测试」即成功。
-
-> **国内邮箱推荐端口 465**（QQ/163 均支持）。Gmail 需要应用专用密码而不是账户密码。
-
-### 2.5 断网短信兜底
-
-**当安卓手机没有网络时**，把重要通知（验证码、来电）通过 **SIM 卡短信** 发到另一台手机（通常是你的 iPhone）。需要安卓卡里还有短信套餐余量。
-
-**配置步骤**：
-1. 在 GotMsg「设置 -> 短信兜底」点「授予短信权限」（安卓系统权限）。
-2. 点「添加」输入**目标手机号**（如 iPhone 号，接收端是另一台手机，**不是** GotMsg 本身）。
-3. 选运营商：
-   - 选了「自动识别」：GotMsg 会发免费查询短信给运营商服务号，解析回执获取余量。
-   - 选了「手动额度」：在「手动短信额度」填入当前套餐短信条数，每次发短信后自动减 1。
-4. 当余量 ≤ 5 时自动暂停，下次打开 App 提醒续费。
-5. 频率限制：每 5 分钟最多发 1 条（避免刷屏），同一条通知 5 分钟内不重复。
-
-> **适用场景**：安卓手机没 WiFi 时，验证码不会丢，漏不了重要登录。
-
----
-
-## 三、自建推送服务（可选）
-
-所有通道都支持自建，更好、更私密、可控。
-
-### 3.1 自建 Bark 服务器
-
-GotMsg 默认用 Bark 官方服务器（`https://api.day.app`），免费够用。自建适合追求完全控制。
-
-**Docker 一键部署**（推荐）：
-```bash
-docker run -d --name bark --restart=unless-stopped \
-  -p 8080:8080 \
-  -v /var/lib/bark:/data \
-  finab/bark-server
-```
-
-然后用 Nginx Proxy Manager 加 HTTPS 域名。详细三种方案对比请看 [Bark 官方文档](https://github.com/Finb/Bark)。
-
-**GotMsg 配置**：服务器地址填 `https://你的域名.com`（不要 `/push` 后缀），Device Key 填你在自建 Bark 上创建的 Key。
-
-### 3.2 自建 ntfy 服务器
-
-[ntfy](https://ntfy.sh) 是为自建设计的，**比 Bark 还简单**--官方直接提供 Docker 一行启动：
-
-```bash
-docker run -d --name ntfy --restart=unless-stopped \
-  -p 80:80 \
-  -v /var/lib/ntfy:/var/lib/ntfy \
-  binwiederhier/ntfy serve
-```
-
-推荐加 Nginx 反代上 HTTPS 域名。完整文档：[docs.ntfy.sh](https://docs.ntfy.sh/install/)。
-
-**GotMsg 配置**：服务器地址填 `https://ntfy.你的域名.com`，Topic 照旧。
-
-### 3.3 自建 Meow 服务器
-Meow 是鸿蒙客户端，服务端一般用 Meow 自带的。GotMsg 端无需配置服务端，只需填 Meow 给你的接口地址 + Key。
-
----
-
-## 四、通知远程回复（Bark / ntfy）
-
-v1.11.0 起，Bark 和 ntfy 转发通知会附带回复入口。接收端在 iPhone 或 Android 上打开回复页并输入内容后，会经 GotMsg 回复中继送回原 Android 手机。GotMsg 优先使用原通知的 Android `RemoteInput` 快捷回复能力。
-
-v1.12.0 起，可在 GotMsg「设置 -> 通知回复」中开启无障碍兼容回复。微信、QQ 等没有提供 `RemoteInput` 时，原 Android 手机会打开通知对应的聊天页面，填写回复并点击明确的发送按钮。该模式需要原手机已解锁，并在系统设置中手动开启「GotMsg 兼容回复」无障碍服务。
-
-Bark：通知点击目标会优先变成回复页，正文也会附带回复链接；普通消息不会再跳微信/QQ等原 App。ntfy：通知会带点击目标、动作按钮和正文里的回复链接；如果 iOS 点通知本体只进入 ntfy App，请点消息正文中的回复链接或通知动作。
-
-使用方法与限制见 [docs/notification-reply.md](docs/notification-reply.md)。接收端不需要安装 iOS 快捷指令，也不需要订阅额外的 `_reply` topic。
-
-> 链接 10 分钟内有效。原生快捷回复可在后台执行；无障碍兼容回复会亮屏并打开原 App，只适用于能从通知进入具体聊天且页面存在可识别输入框和发送按钮的消息。付款、订单、营销等非聊天通知不能回复。
-
----
-
-## 五、使用建议
-
-- **只想收验证码**：进入「过滤」页，开启「验证码自动提取」和「广告过滤」；再到「应用」页切到白名单模式，只勾选短信类 App。
+- **只想收验证码**：进入「过滤」页，开启「验证码自动提取」，把「广告过滤」等按需开启；再到「应用」页切到白名单模式，只勾选短信类 App。
 - **想同步聊天**：保持黑名单模式（默认），在「过滤」页开启「微信 / QQ / Telegram 优化」。
 - **通知没推过来**：先看「日志」页，每条通知（无论转发、过滤还是失败）都会记录原因。
-- **想让通知带图标**：见下方「应用图标」一节。
-- **电话通知不工作**：MIUI 不向第三方监听器分发系统电话通知，GotMsg 通过轮询 `getCallState()` 绕过此限制。需授予「电话」权限（设置 -> 应用 -> GotMsg -> 权限 -> 电话）。
-- **断网收不到通知**：开启「设置 -> 短信兜底」并填好 iPhone 号码、授予短信权限。断网时验证码和来电走短信（消耗套餐额度，5 分钟限 1 条）。
-- **想全平台通知**：可同时启用多个通道（勾选每个通道的多个条目），所有启用的会同时收到。
+- **想让通知带图标**：参考下方「应用图标」一节。
+- **电话通知不工作**：MIUI 会把系统电话通知限制为不向第三方通知监听器分发，本 App 通过轮询 `getCallonyState()` 绕过此限制。需要授予「电话」权限（设置 → 应用 → GotMsg → 权限 → 电话）。
+- **断网收不到通知**：开启「设置 → 断网短信兜底」，填好 iPhone 号码、授予短信权限、设好手动额度。断网时验证码和来电会走短信（消耗套餐额度，5 分钟限 1 条）。
 
----
+## 应用图标
 
-## 六、应用图标
+Bark 的 `icon` 字段需要一个公网可访问的图片 URL。GotMsg 支持把已安装 App 的图标批量导出到你选择的目录，方便上传到你自己的图床。
 
-Bark 和 ntfy 的通知 `icon` 字段需要公网可访问的图片 URL。GotMsg 支持把已安装 App 的图标批量导出，方便上传到你自己的图床。
-
-规则：转发时 `icon = 图标 URL 前缀 + 安卓包名 + .png`。在「设置 -> 应用图标」里：
+规则：转发时 `icon = 图标 URL 前缀 + 安卓包名 + .png`。在「设置 → 应用图标」里：
 
 1. 填写图标 URL 前缀，例如 `https://你的图床域名/icons/`。
-2. 选择一个目录，点「导出图标」，把该目录下所有 App 的图标以 `包名.png` 形式导出。
+2. 选择一个目录，点「导出图标」，会把所有 App 图标以 `包名.png` 的形式导出。
 3. 把导出的图片上传到你的图床对应目录。
 
 留空前缀则不显示图标。
 
----
+## 自建 Bark 服务（可选）
 
-## 七、界面截图
+GotMsg 默认用 Bark 官方服务器（`https://api.day.app`），免费够用。如果想完全自控、不限速、不依赖第三方，可以自建 Bark Server。下面是三种零成本方案：
+
+### 方案 1：Vercel 云托管（最适合新手）
+
+把 Bark 后端跑在 Vercel 的 Serverless 上，每次推送触发一个云函数，不挂进程、完全免费。
+
+- 平台：[Vercel](https://vercel.com) · 代码：[GitHub](https://github.com)
+- 在 GitHub 搜索 `bark-server-vercel`，项目 README 里通常有 **Deploy with Vercel** 按钮，一键克隆部署
+
+### 方案 2：Cloudflare Workers（最稳定）
+
+把轻量 JS 转发代码部署到 Cloudflare 全球边缘节点，免费额度每天 10 万次请求，个人用属于「溢出」状态。
+
+- 平台：[Cloudflare](https://www.cloudflare.com)
+- 在 GitHub 搜索 `bark-server-cloudflare` 或 `bark cloudflare worker`，在 Cloudflare 后台新建 Worker 粘贴脚本保存即可
+
+### 方案 3：免费 VPS + Docker（最高自主权）
+
+在永久免费的 Linux 虚拟机上用 Docker 跑官方 bark-server。
+
+- 官方服务端：[finab/bark-server](https://github.com/finab/bark-server)
+- 反向代理 + 免费 HTTPS 证书：[Nginx Proxy Manager](https://nginxproxymanager.com)
+- 免费 VPS：[Oracle Cloud 永久免费层](https://www.oracle.com/cloud/free/)、[AWS 一年免费套餐](https://aws.amazon.com/free/)
+
+### ⚠️ 防坑提示
+
+国内网络下，Vercel 的 `*.vercel.app` 和 Cloudflare 的 `*.workers.dev` 二级域名可能间歇性无法访问。**终极方案**：注册一个便宜的个人域名（或找免费域名），解析托管到 Cloudflare，然后把 Vercel / Worker 绑到**自定义域名**上——既稳定又秒达。
+
+自建完成后，在「设置 → Bark 服务器」里填自建地址即可。
+
+## 技术栈
+
+- Kotlin + Jetpack Compose（Material 3）
+- AndroidX DataStore（持久化设置与日志）
+- OkHttp（Bark / ntfy / Meow / 更新检查）
+- WorkManager（失败重试）
+- Navigation Compose（单 Activity 多页面）
+- 最低 Android 14（API 34），目标 Android 16（API 36）
+

-# A2iReply 快捷指令迁移说明
-
-v1.11.0 已移除旧的 iOS 快捷指令和 ntfy `_reply` topic 方案。请删除原有的 `A2iReply` 快捷指令；GotMsg 不再订阅或使用 `_reply` topic。
-
-新版本会在可回复的 ntfy 通知中直接附加一次性网页链接。iPhone 和 Android 都可点开网页输入回复，不需要额外配置。
-
-完整说明见 [notification-reply.md](notification-reply.md)。

-# 通知远程回复
-
-GotMsg v1.11.0 起支持从 iPhone 或另一台 Android 设备打开 Bark / ntfy 通知里的回复链接。回复会回到运行 GotMsg 的原 Android 手机。v1.12.0 起，除了原生通知快捷回复，还可选择使用无障碍兼容回复处理微信、QQ 等没有提供系统回复动作的聊天通知。
-
-## 使用方法
-
-1. 在原 Android 手机的 GotMsg 中启用至少一个 Bark 或 ntfy 配置。
-2. 保持 GotMsg 的通知读取权限，并让原手机联网。
-3. 如需回复没有系统快捷回复入口的微信、QQ 等通知，在 GotMsg「设置 -> 通知回复」中开启「无障碍兼容回复」，再到系统无障碍设置中开启「GotMsg 兼容回复」。
-4. 每条 Bark / ntfy 转发通知都会带回复入口。Bark 接收端直接点通知即可打开回复页，通知正文也会附带回复链接；普通消息不会再跳微信/QQ等原 App。ntfy 接收端可点通知、通知动作或正文中的回复链接；如果 iOS 点通知本体只进入 ntfy App，请点消息正文里的回复链接。
-5. 网页提交后，原 Android 手机先尝试原通知的 `RemoteInput`；没有该动作时才使用已启用的无障碍兼容回复。GotMsg 的「日志」页会记录结果。
-
-接收端无需安装 iOS 快捷指令，也无需创建或订阅 `_reply` topic。现有 ntfy server、topic 和 token 配置不需要改动。
-
-## 生效条件
-
-- 原生模式要求原 App 在该条通知上提供允许自由文本的 Android `RemoteInput` 动作，可以在后台完成。
-- 无障碍兼容模式会使用通知的会话入口打开原 App，只对白名单中的微信、QQ、支付宝、淘宝、钉钉生效。页面必须是聊天页，并存在可识别的输入框和明确的「发送」按钮。
-- 无障碍兼容模式要求原手机已解锁；执行时会亮屏、切换到对应 App。输入框已有草稿时会停止，不会覆盖草稿。
-- 付款、订单、验证码、营销和系统通知通常没有聊天输入框，即使带回复链接也不能发送回复。
-- 原通知不能被划掉或被新通知替换；进程未重启时 GotMsg 会短暂缓存通知入口，降低通知更新导致的失败概率。
-- 回复链接从通知转发起 10 分钟内有效，并且只能成功提交一次。
-- 原 Android 手机必须联网，GotMsg 进程和通知监听服务需要正常工作。
-- 某些 App 或定制系统不会向无障碍服务暴露聊天控件；这种情况下网页会显示具体失败原因。
-
-## 安全说明
-
-- 每条通知使用独立的 256 位随机回复令牌。令牌放在 URL fragment 中，不会随首次页面请求进入服务器访问日志。
-- GotMsg 安装时生成独立设备 ID 和密钥；原手机与中继 API 之间的注册、拉取和确认请求均需设备鉴权。
-- 中继只持久化设备密钥和回复令牌的 SHA-256 哈希。提交后的回复正文会在中继中短暂保存，处理完成后最多保留 24 小时用于状态查询和故障排查。
-- 拿到有效回复链接的人可在有效期内提交一次回复，因此不要转发或公开该链接。
-- 无障碍兼容回复仅在收到有效的一次性回复事件时运行，严格校验目标包名，并且只点击文字明确匹配「发送」的控件。该权限能够读取当前窗口内容，只应在你信任的原 Android 手机上启用。
-- 回复服务使用 `https://r.gotmsg.pp.ua`，不可在 App 设置中修改。部署或域名变更时需同步修改 `ReplyFeature.RELAY_BASE_URL` 并重新发布 APK。
-
-## 常见失败
-
-- `回复链接已过期`：通知转发已超过 10 分钟。
-- `原通知已消失`：原 Android 手机上的通知已被清除或替换。
-- `请在 GotMsg 设置中开启无障碍兼容回复服务`：应用内开关已打开，但系统无障碍权限尚未开启。
-- `原手机需解锁后才能回复`：解锁原手机后，重新从一条新通知发起回复。
-- `未找到聊天输入框` / `未找到明确的发送按钮`：通知没有进入可回复聊天页，或原 App 当前版本的界面需要重新适配。
-- `聊天输入框已有未发送内容`：GotMsg 为避免覆盖原手机草稿而主动停止。
-- `原手机未确认回复`：中继未在超时时间内收到原手机处理结果，检查原手机网络、后台限制和 GotMsg 通知读取权限。

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
