+# 项目记忆包 — go_win_template
+
+> 此目录为 AI 辅助开发项目的记忆索引。
+> 核心工具：**CodeGraph**（代码知识图谱），用于快速检索项目符号和调用关系。
+> 当 `.codegraph/` 目录存在时，优先使用 CodeGraph 探索代码，而非 grep/find。

+## 🕸️ CodeGraph 使用指南
+
+### 安装状态
+```
+已全局安装: @colbymchenry/codegraph@1.6.0
+项目索引: .codegraph/ (25 files, 431 nodes, 947 edges)
+MCP 集成: opencode (已配置)
+```
+
+### 核心命令
+
+```bash
+# 初始化/重建索引
+codegraph init [path]
+
+# 查看项目文件结构
+codegraph files
+
+# 查看索引状态和统计
+codegraph status
+
+# 搜索符号
+codegraph query <search_term>
+
+# 探索代码区域（源码 + 调用路径）—— 最常用的命令
+codegraph explore "<topic>"
+
+# 构建任务上下文（相关符号、关系、代码块）
+codegraph context "<task>"
+
+# 查看单个符号的源码和调用链
+codegraph node <symbol_name>
+
+# 查找谁调用了某个函数
+codegraph callers <symbol>
+
+# 查找某个函数调用了什么
+codegraph callees <symbol>
+
+# 分析修改某符号的影响范围
+codegraph impact <symbol>
+
+# 查找受影响的测试文件
+codegraph affected [files...]
+
+# 更新索引（增量同步）
+codegraph sync
+```
+
+### 典型工作流
+
+```bash
+# 开发新功能前，先构建上下文
+codegraph context "实现新的插件功能"
+
+# 查看关键入口函数的完整调用链
+codegraph node "App.Startup"
+
+# 探索某个模块的架构
+codegraph explore "payment service architecture"
+
+# 修改代码前确认影响范围
+codegraph impact "CreateUser"
+```
+
+### 在 AI 对话中的使用
+
+当需要理解或修改代码时，**优先使用 CodeGraph 而不是 grep**：
+
+```bash
+# ❌ 不要这样（慢且碎片化）
+grep -r "FunctionName" --include="*.go" .
+
+# ✅ 应该这样（精准且带上下文）
+codegraph explore "FunctionName"
+codegraph node "FunctionName"
+codegraph callees "FunctionName"
+```

+## 🔌 插件系统
+
+### 插件列表
+
+| 插件名 | Build Tag | 默认状态 | 功能 |
+|--------|-----------|----------|------|
+| `concurrent` | `-tags concurrent` | ✅ 启用 | 高并发工具集 |
+| `payment` | `-tags payment` | ✅ 启用 | 支付授权与订单管理 |
+| `iconfont` | `-tags iconfont` | ❌ 禁用 | 阿里IconFont图标库 |
+| `ai` | `-tags ai` | ❌ 禁用 | AI大模型集成 |
+
+### 运行时配置（无需重新编译）
+
+编辑 `config/plugin.json` 即可切换插件开关：
+```json
+{
+  "plugins": {
+    "payment": {
+      "enabled": true,
+      "params": { "app_id": "...", "api_key": "...", "base_url": "..." }
+    }
+  }
+}
+```
+
+### 编译时启用（完全排除二进制）
+
+```bash
+# 仅基础功能
+wails build
+
+# 加支付插件
+wails build -tags payment
+
+# 加 AI 插件
+wails build -tags ai
+
+# 全部启用
+wails build -tags "payment,ai,iconfont"
+
+# 环境变量覆盖
+PLUGIN_AI=true wails build
+```
+
+---
+
+## 💰 支付接口（IPC — 前端可调用）
+
+| Go 方法 | 说明 |
+|---------|------|
+| `PayLogin()` | 登录授权，获取 access_token |
+| `PayCheckAuth()` | 查询授权状态 |
+| `PayRefreshToken()` | 主动刷新令牌 |
+| `PayGetAccountInfo()` | 获取账号信息 |
+| `PayQueryOrder(orderID)` | 查订单 |
+| `PayQueryOrderByOutNo(outTradeNo)` | 按商户号查订单 |
+| `PayRequestRefund(orderID, amount, reason)` | 申请退款 |
+| `PayGetBill(page, pageSize)` | 分页账单 |
+| `PayGetBillByDate(start, end)` | 按日期查账单 |
+
+---
+
+## 🚀 开发命令
+
+```bash
+# 开发模式（热更新，自动选端口）
+wails dev
+
+# 构建 Windows exe
+wails build
+
+# 重新生成前端 JS 绑定（新增 IPC 方法后执行）
+wails generate module
+
+# 更新 CodeGraph 索引
+codegraph sync
+
+# 查看项目结构索引
+codegraph files
+```
+
+---
+
+## ⚠️ 重要注意事项
+
+1. **端口冲突**: Wails dev 模式 Vite 自动选可用端口（`strictPort: false`），多实例不冲突
+2. **生产模式**: 静态资源打包进 exe，无端口暴露，用户无法直接访问端口
+3. **托盘图标**: Wails v2 标准路径 `trayicons/icon.png`，名称即 ID（`Image: "icon"`）
+4. **支付插件**: 需在 `config/plugin.json` 的 `params` 中配置 `app_id`、`api_key`、`base_url`
+5. **CodeGraph**: 索引存储在 `.codegraph/codegraph.db`，修改代码后运行 `codegraph sync` 同步

+## About
+
+This is the official Wails React-TS template.
+
+You can configure the project by editing `wails.json`. More information about the project settings can be found
+here: https://wails.io/docs/reference/project-config
+
+## Live Development
+
+To run in live development mode, run `wails dev` in the project directory. This will run a Vite development
+server that will provide very fast hot reload of your frontend changes. If you want to develop in a browser
+and have access to your Go methods, there is also a dev server that runs on http://localhost:34115. Connect
+to this in your browser, and you can call your Go code from devtools.
+
+## Building
+
+To build a redistributable, production mode package, use `wails build`.

+# Build Directory
+
+The build directory is used to house all the build files and assets for your application. 
+
+The structure is:
+
+* bin - Output directory
+* darwin - macOS specific files
+* windows - Windows specific files
+
+## Mac
+
+The `darwin` directory holds files specific to Mac builds.
+These may be customised and used as part of the build. To return these files to the default state, simply delete them
+and
+build with `wails build`.
+
+The directory contains the following files:
+
+- `Info.plist` - the main plist file used for Mac builds. It is used when building using `wails build`.
+- `Info.dev.plist` - same as the main plist file but used when building using `wails dev`.
+
+## Windows
+
+The `windows` directory contains the manifest and rc files used when building with `wails build`.
+These may be customised for your application. To return these files to the default state, simply delete them and
+build with `wails build`.
+
+- `icon.ico` - The icon used for the application. This is used when building using `wails build`. If you wish to
+  use a different icon, simply replace this file with your own. If it is missing, a new `icon.ico` file
+  will be created using the `appicon.png` file in the build directory.
+- `installer/*` - The files used to create the Windows installer. These are used when building using `wails build`.

+-----------------------------------------------------------
+SIL OPEN FONT LICENSE Version 1.1 - 26 February 2007
+-----------------------------------------------------------
+
+PREAMBLE
+The goals of the Open Font License (OFL) are to stimulate worldwide
+development of collaborative font projects, to support the font creation
+efforts of academic and linguistic communities, and to provide a free and
+open framework in which fonts may be shared and improved in partnership
+with others.
+
+The OFL allows the licensed fonts to be used, studied, modified and
+redistributed freely as long as they are not sold by themselves. The
+fonts, including any derivative works, can be bundled, embedded, 
+redistributed and/or sold with any software provided that any reserved
+names are not used by derivative works. The fonts and derivatives,
+however, cannot be released under any other type of license. The
+requirement for fonts to remain under this license does not apply
+to any document created using the fonts or their derivatives.
+
+DEFINITIONS
+"Font Software" refers to the set of files released by the Copyright
+Holder(s) under this license and clearly marked as such. This may
+include source files, build scripts and documentation.
+
+"Reserved Font Name" refers to any names specified as such after the
+copyright statement(s).
+
+"Original Version" refers to the collection of Font Software components as
+distributed by the Copyright Holder(s).
+
+"Modified Version" refers to any derivative made by adding to, deleting,
+or substituting -- in part or in whole -- any of the components of the
+Original Version, by changing formats or by porting the Font Software to a
+new environment.
+
+"Author" refers to any designer, engineer, programmer, technical
+writer or other person who contributed to the Font Software.
+
+PERMISSION & CONDITIONS
+Permission is hereby granted, free of charge, to any person obtaining
+a copy of the Font Software, to use, study, copy, merge, embed, modify,
+redistribute, and sell modified and unmodified copies of the Font
+Software, subject to the following conditions:
+
+1) Neither the Font Software nor any of its individual components,
+in Original or Modified Versions, may be sold by itself.
+
+2) Original or Modified Versions of the Font Software may be bundled,
+redistributed and/or sold with any software, provided that each copy
+contains the above copyright notice and this license. These can be
+included either as stand-alone text files, human-readable headers or
+in the appropriate machine-readable metadata fields within text or
+binary files as long as those fields can be easily viewed by the user.
+
+3) No Modified Version of the Font Software may use the Reserved Font
+Name(s) unless explicit written permission is granted by the corresponding
+Copyright Holder. This restriction only applies to the primary font name as
+presented to the users.
+
+4) The name(s) of the Copyright Holder(s) or the Author(s) of the Font
+Software shall not be used to promote, endorse or advertise any
+Modified Version, except to acknowledge the contribution(s) of the
+Copyright Holder(s) and the Author(s) or with their explicit written
+permission.
+
+5) The Font Software, modified or unmodified, in part or in whole,
+must be distributed entirely under this license, and must not be
+distributed under any other license. The requirement for fonts to
+remain under this license does not apply to any document created
+using the Font Software.
+
+TERMINATION
+This license becomes null and void if any of the above conditions are
+not met.
