+#### **4.1.6 编译与分发说明（path 子包 vs 单包）**
+- 当前结构：插件（ai_chat_assistant）+ 仓库内 path 依赖（packages/ai_chat_core、packages/basic_intl）。
+
+- 下游集成（pubspec）仅需：
+  ```yaml
+  ai_chat_assistant:
+    git:
+      url: <repo_url>
+      ref: <branch_or_tag>
+  ```
+- Flutter 构建行为：
+  1. 克隆仓库 → 解析主插件 pubspec → 解析 path 子包 → 汇总全部 Dart 源码。
+  2. Debug：JIT，Release：统一 AOT 编译为一个 snapshot（无包边界差异）。
+- 性能与产物差异：将子包“内联”进 lib/ 与保持 path 组织，在编译后无本质差异（tree shaking 后输出等价）。
+- 适用场景对比：
+  | 目标 | 保持多包 | 合并单包 |
+  | ---- | -------- | -------- |
+  | 代码隔离 / 复用 | 优 | 弱 |
+  | 发布到 pub.dev | 需逐包发布 | 更简单 |
+  | 测试隔离性 | 优 | 一般 |
+  | 用户认知成本 | 稍高 | 低 |
+- 暂不需发布：保持 path 结构即可；若未来开放生态 → 发布次序：ai_chat_core → basic_intl → ai_chat_assistant。
+
+#### **4.1.7 AAR 与闭源分发说明**
+| 诉求 | 可行性 | 说明 |
+| ---- | ------ | ---- |
+| 给“另一个 Flutter App”仅提供预编译 AAR 使用 | 不推荐/不可行 | Flutter 仍需源文件参与整体编译流程 |
+| 给纯原生 Android App 内嵌使用 | 可用 `flutter build aar` | 适用于“原生 App 集成 Flutter 模块”，不是插件分发 |
+| Dart 逻辑闭源 | 官方未支持 | 只能转移核心到 native/FFI 或服务端 |
+
+结论：对 Flutter 使用方，直接 Git 依赖即可，无需 AAR。
