+避免线上包连到开发机。

 ## 生产打包（Android）

-生产包只包含以下两个 ABI，**打成一个 APK**，不做 split：
+两个渠道出两种产物，源码同一套：

-| ABI | 适用设备 |
-| --- | --- |
-| `arm64-v8a` | 现代手机（64 位） |
-| `armeabi-v7a` | 老 32 位机 |
-
-```bash
-flutter build apk --release --target-platform android-arm64,android-arm
-# 产出单个：build/app/outputs/flutter-apk/app-release.apk（约 37MB）
-```
+| 渠道 | 产物 | 命令 | 体积 |
+| --- | --- | --- | --- |
+| Google Play | AAB（按设备下发） | `flutter build appbundle --release` | 上传 28MB，用户下载约 8MB |
+| 国内各大市场 | 通用 APK（arm64 + v7） | `flutter build apk --release` | 约 13MB |

 说明：

 - `android/app/build.gradle.kts` 的 `release` 已配置 `abiFilters`，只保留 `arm64-v8a` 与 `armeabi-v7a`，插件也不会再带入 `x86_64` 原生库。
- `x86_64` 只用于模拟器，不进入生产包。
- 不要直接运行 `flutter build apk --release`：默认会编译三套原生库，包体约 57MB。
- 只有需要进一步压缩单机下载体积时，才考虑 `--split-per-abi` 出分架构包（arm64 约 21MB、armv7 约 19MB），默认不用。
+- `android/gradle.properties` 里固定了 `split-debug-info=build/symbols` 与 `dart-obfuscation=true`，**IDE 里点 Build APK / Build App Bundle 也会生效**：`libapp.so` 从 ~8MB/ABI 降到 ~1.1MB/ABI。
+- `useLegacyPackaging = true`：原生库以压缩形式存储，这是国内 APK 从 40MB 降到 13MB 的主要原因；代价是安装时解压。
+- **每次发版都要归档 `build/symbols`**，线上崩溃栈需要它还原。
+- release 仍在用 debug 签名（`build.gradle.kts` 的 TODO），上架前必须换成正式 keystore。
+- 不要用 `--split-per-abi`：与 `abiFilters` 冲突；Play 的 AAB 已经按设备拆好。
+
+## 生产打包（iOS）
+
+```bash
+# 正式签名（需要 iOS Distribution 证书 + App Store 描述文件）
+flutter build ipa --release
+
+# 只有 Apple Development 证书时：出开发签名 IPA，只能装已注册设备
+flutter build ipa --release --export-method development
+```
+
+产物在 `build/ios/ipa/*.ipa`。画中画依赖 `UIBackgroundModes` 里的 `audio` 与
+`AVPictureInPictureController`，改动 `ios/Runner/Info.plist` 或 `AppDelegate.swift`
+后要重新构建，热重载不会生效。

 ## 门禁

 ```bash
-dart analyze lib test
+dart analyze
 flutter test
 flutter build apk --debug
 ```

-测试文件按模块放在 `test/` 下，用例名使用
+当前基线：`dart analyze` 仅 1 条既存 info（`intl` 未在 `pubspec.yaml` 声明)；
+`flutter test` 全量 775 例通过。测试文件按模块放在 `test/` 下，用例名使用
 `should_<期望>_when_<条件>`。真实后端联调测试在服务未启动时会跳过。

 ## 当前边界

- 下载仅管理服务端授权，不落盘、不续传、不支持离线播放。
- 没有独立搜索接口，搜索能力尚未形成完整闭环。
+- 下载会落盘并支持离线播放，但不支持断点续传：中途失败会丢弃 `.part` 重下。
+- 支付与金币：客户端已有钱包、商品、下单接口与页面，商店票据校验依赖服务端配置凭据。
 - 站内通知没有已读/未读和红点状态。
- 支付、金币和会员权益尚未形成客户端闭环。
- Android 支持系统画中画；iOS 画中画尚未接入。
+- 播放清晰度切换会保留旧画面 500ms 掩盖闪屏，切换瞬间的进度以相对位置续播。
