+# Contributing Guide
+
+Thank you for contributing to this project.
+
+This repository follows a release-first workflow: `main` is the default public branch, while releases are prepared through `release/*` branches.
+
+---
+
+## Branch Model
+
+- `main`: stable release branch and default branch
+- `dev`: day-to-day integration branch for maintainers
+- `release/*`: release preparation branches for maintainers
+- Recommended branch names for external contributors:
+  - `fix/*`: bug fixes
+  - `feature/*`: new features or enhancements
+
+Maintainer release flow:
+
+```text
+feature/* / fix/* -> dev -> release/* -> main -> tag(vX.Y.Z)
+```
+
+---
+
+## How External Contributors Should Open Pull Requests
+
+Whether your branch is `fix/*` or `feature/*`, external contributors should **open pull requests directly against `main`**.
+
+Reasons:
+
+- `main` is the default branch, so the PR entry point is clearer
+- merged contributions are immediately visible on the default branch
+- maintainers can handle downstream sync and release preparation in one place
+
+Recommended flow:
+
+1. Fork this repository
+2. Create a branch in your fork (`fix/*` or `feature/*` is recommended)
+3. Make your changes and perform basic self-checks
+4. Push the branch to your fork
+5. Open a pull request against the `main` branch of this repository
+
+---
+
+## Pull Request Requirements
+
+Please keep each pull request focused, reviewable, and easy to validate.
+
+Recommended expectations:
+
+- one pull request should address one logical change
+- use a clear title that explains the purpose
+- include the following in the description:
+  - background and problem statement
+  - key changes
+  - impact scope
+  - validation method
+- include screenshots or recordings for UI changes when helpful
+- explicitly mention risk and rollback notes for compatibility, data, or build-chain changes
+
+---
+
+## Merge Strategy for Maintainers
+
+Pull requests merged into `main` should generally use **Squash and merge**.
+
+Reasons:
+
+- keeps `main` history clean and linear
+- maps each PR to a single commit on `main`
+- reduces release, audit, and rollback complexity
+
+---
+
+## Maintainer Sync Rules
+
+Because external pull requests are merged directly into `main`, maintainers must sync `main` back to development and release branches to avoid branch drift.
+
+### 1. Sync `main` -> `dev` (required)
+
+The automatic GitHub Actions sync workflow has been removed.
+Maintainers should sync `main` back to `dev` manually when needed:
+
+```bash
+git checkout dev
+git pull
+git merge main
+git push
+```
+
+### 2. Create `release/*` from `dev`
+
+Before a release, create a release branch from `dev`, for example:
+
+```bash
+git checkout dev
+git pull
+git checkout -b release/v0.6.0
+git push -u origin release/v0.6.0
+```
+
+### 3. Release from `release/*` back to `main`
+
+When release preparation is complete, merge the release branch back into `main` and create a tag:
+
+```bash
+git checkout main
+git pull
+git merge release/v0.6.0
+git push
+git tag v0.6.0
+git push origin v0.6.0
+```
+
+### 4. Sync `main` back to `dev` after release
+
+After the release, the same automation still applies. If needed, you can run the workflow manually (`workflow_dispatch`) or execute the fallback commands:
+
+```bash
+git checkout dev
+git pull
+git merge main
+git push
+```
+

+# 贡献指南
+
+感谢你对本项目的贡献。
+
+本项目采用“发布优先（`main` 为默认分支）+ `release/*` 分支发版”的协作模型。为减少分支漂移与 PR 处理成本，请在提交贡献前先阅读本指南。
+
+---
+
+## 分支模型
+
+- `main`：稳定发布分支，也是仓库默认分支
+- `dev`：日常开发集成分支，主要供维护者使用
+- `release/*`：发布准备分支，主要供维护者使用
+- 外部贡献者建议使用以下分支命名：
+  - `fix/*`：问题修复
+  - `feature/*`：功能新增或增强
+
+维护者发布流转如下：
+
+```text
+feature/* / fix/* -> dev -> release/* -> main -> tag(vX.Y.Z)
+```
+
+---
+
+## 外部贡献者如何提 Pull Request
+
+无论是 `fix/*` 还是 `feature/*`，**外部贡献者统一直接向 `main` 发起 Pull Request**。
+
+这样做的原因：
+
+- `main` 是默认分支，PR 入口更直观
+- 合并后贡献会直接体现在默认分支
+- 便于维护者统一做后续同步与发版整理
+
+建议流程：
+
+1. Fork 本仓库
+2. 从你自己的仓库创建分支（建议命名为 `fix/*` 或 `feature/*`）
+3. 完成代码修改，并进行必要自检
+4. 推送到你的远程分支
+5. 向本仓库的 `main` 分支发起 Pull Request
+
+---
+
+## Pull Request 要求
+
+请尽量保证 PR 单一、清晰、可审核。
+
+建议遵循以下要求：
+
+- 一个 PR 只解决一类问题，避免混入无关改动
+- 标题清晰说明改动目的
+- 描述中说明：
+  - 背景与问题
+  - 变更点
+  - 影响范围
+  - 验证方式
+- 如涉及 UI 调整，建议附截图或录屏
+- 如涉及兼容性、数据变更或构建链路调整，请明确说明风险和回滚方式
+
+---
+
+## PR 合并策略（维护者）
+
+`main` 分支上的 PR 建议使用 **Squash and merge**。
+
+原因：
+
+- 保持 `main` 历史干净、线性
+- 每个 PR 在 `main` 上对应一个清晰提交
+- 降低发布排查与回滚成本
+
+---
+
+## 维护者同步规则
+
+由于外部 PR 会直接合入 `main`，维护者必须及时将 `main` 的变更同步到开发与发布分支，避免分支漂移。
+
+### 1. main → dev 同步（必做）
+
+仓库已移除 GitHub Actions 自动回灌 workflow。
+当前统一采用手动方式将 `main` 同步回 `dev`：
+
+```bash
+git checkout dev
+git pull
+git merge main
+git push
+```
+
+### 2. 发版前从 dev 切 release/*
+
+发布前由维护者基于 `dev` 创建发布分支，例如：
+
+```bash
+git checkout dev
+git pull
+git checkout -b release/v0.6.0
+git push -u origin release/v0.6.0
+```
+
+### 3. release/* → main 发版
+
+发布准备完成后，将 `release/*` 合并回 `main`，并打标签发布：
+
+```bash
+git checkout main
+git pull
+git merge release/v0.6.0
+git push
+git tag v0.6.0
+git push origin v0.6.0
+```
+
+### 4. main 回流到 dev（发版后必做）
+
+发布完成后，仍沿用同一套自动化流程；如有需要，也可以手动触发 `workflow_dispatch`，或执行以下兜底命令，确保开发线与发布线一致：
+
+```bash
+git checkout dev
+git pull
+git merge main
+git push
+```
+
+---
+
+## 提交建议
+
+建议保持提交信息简洁、明确，便于维护者审查与后续追踪。
+
+推荐格式：
+
+```text
+emoji type(scope): 中文描述
+```
+
+示例：
+
+```text
+🔧 fix(ci): 修复 Windows AMD64 下 DuckDB 驱动构建工具链
+✨ feat(redis): 新增 Stream 类型数据浏览支持
+♻️ refactor(datagrid): 优化大表横向滚动与渲染结构
+```
+
+---
+
+## 其他说明
+
+- 文档、构建链路、驱动兼容性相关改动，请尽量附带验证结果
+- 若改动较大，建议先提 Issue 或 Draft PR，先对齐方案再实施
+- 如提交内容与项目当前架构方向冲突，维护者可能要求收敛范围后再合并
+
+感谢你的贡献。

-# HighGo 可选代码优化建议
-
-## 一、sslmode 配置优化
-
-### 当前状态
-
-**文件**：`internal/db/highgo_impl.go:43`
-
-**当前代码**：
-```go
-q.Set("sslmode", "disable")
-```
-
-### 建议修改
-
-根据瀚高官方文档，sslmode 的默认值应该是 `require`。建议修改为：
-
-```go
-q.Set("sslmode", "require")
-```
-
-### 修改原因
-
-1. **符合官方规范**：瀚高官方文档明确指出默认 sslmode 为 `require`
-2. **安全性提升**：启用 SSL 加密可以保护数据传输安全
-3. **生产环境最佳实践**：生产环境应该启用 SSL 连接
-
-### 是否需要修改？
-
-**不一定需要修改**，取决于您的实际环境：
-
-#### 保持 `disable` 的场景：
-- ✅ 开发/测试环境
-- ✅ HighGo 服务器未配置 SSL 证书
-- ✅ 内网环境，不需要加密传输
-- ✅ 快速测试连接功能
-
-#### 修改为 `require` 的场景：
-- ✅ 生产环境
-- ✅ HighGo 服务器已配置 SSL 证书
-- ✅ 跨网络连接，需要加密保护
-- ✅ 符合安全合规要求
-
-### 如何修改
-
-如果您决定修改，可以使用以下命令：
-
-**方式 1：直接修改（固定为 require）**
-```go
-// 文件：internal/db/highgo_impl.go 第 43 行
-q.Set("sslmode", "require")
-```
-
-**方式 2：可配置（推荐）**
-
-如果希望让用户可以选择 sslmode，可以修改为：
-
-```go
-// 在 getDSN 方法中
-sslmode := "disable" // 默认值
-if config.SSLMode != "" {
-    sslmode = config.SSLMode
-}
-q.Set("sslmode", sslmode)
-```
-
-然后在 `internal/connection/connection.go` 的 `ConnectionConfig` 结构体中添加字段：
-
-```go
-type ConnectionConfig struct {
-    // ... 现有字段
-    SSLMode string `json:"sslMode,omitempty"` // SSL 模式：disable, require, verify-ca, verify-full
-}
-```
-
-前端 UI 也需要相应添加 sslmode 选择控件。
-
-### 测试建议
-
-修改后请务必测试：
-
-1. **SSL 启用测试**：
-   - 连接配置了 SSL 的 HighGo 服务器
-   - 验证连接成功
-
-2. **SSL 禁用测试**：
-   - 连接未配置 SSL 的 HighGo 服务器
-   - 验证是否会报错（如果设置为 `require` 会报错）
-
-3. **兼容性测试**：
-   - 测试现有的 HighGo 连接配置是否仍然可用
-
-## 二、其他可选优化
-
-### 1. 默认端口提示优化
-
-**文件**：`frontend/src/components/ConnectionModal.tsx`
-
-**当前状态**：HighGo 的默认端口已正确设置为 5866
-
-**建议**：无需修改，已符合官方规范
-
-### 2. 默认数据库名称
-
-**文件**：`internal/db/highgo_impl.go:33`
-
-**当前代码**：
-```go
-if dbname == "" {
-    dbname = "highgo" // HighGo default database
-}
-```
-
-**建议**：无需修改，已符合官方规范（默认数据库为 `highgo`）
-
-### 3. 默认用户名
-
-**当前状态**：未在代码中硬编码默认用户名
-
-**瀚高官方默认**：`sysdba`
-
-**建议**：
-- 可以在前端 UI 的 HighGo 连接表单中，将用户名输入框的 placeholder 设置为 `sysdba`
-- 但不建议硬编码默认值，让用户自行输入更安全
-
-## 三、总结
-
-### 必须修改的项目
-- ✅ **无**（当前代码已基本符合规范）
-
-### 建议修改的项目
-1. **sslmode 配置**（根据实际环境决定）
-   - 开发环境：保持 `disable`
-   - 生产环境：修改为 `require`
-
-### 可选优化的项目
-1. 将 sslmode 改为可配置（需要修改前后端）
-2. 前端 UI 添加 sslmode 选择控件
-3. 用户名输入框添加 `sysdba` 提示
-
-## 四、修改优先级
-
-**优先级 1（高）**：
-- 集成瀚高 SM3 驱动（参考 `HighGo_SM3_Integration_Guide.md`）
-
-**优先级 2（中）**：
-- 根据部署环境调整 sslmode 配置
-
-**优先级 3（低）**：
-- 将 sslmode 改为可配置
-- UI 优化（placeholder 提示等）
-
-## 五、下一步行动
-
-建议按以下顺序执行：
-
-1. **先集成 SM3 驱动**（参考集成指南）
-2. **测试基本连接功能**（使用 sslmode=disable）
-3. **如果生产环境需要 SSL**，再修改 sslmode 配置
-4. **验证所有功能正常**后，考虑可选优化项
-
----
-
-**注意**：所有代码修改都应该在集成 SM3 驱动并验证基本功能正常后再进行。

-# HighGo SM3 国密驱动集成指南
-
-## 一、背景说明
-
-HighGo（瀚高）数据库需要使用支持 SM3 国密认证的 PostgreSQL 驱动。瀚高官方提供了基于 `lib/pq` 的安全增强版本。
-
-## 二、集成步骤
-
-### 步骤 1：下载瀚高 pq 驱动
-
-1. 访问百度网盘链接：
-   ```
-   https://pan.baidu.com/s/1xuz6uJz0utRgKWecXhpOiA?pwd=o0tj
-   ```
-
-2. 下载驱动源码压缩包
-
-### 步骤 2：放置驱动源码
-
-1. 在项目根目录创建 vendor 目录（如果不存在）：
-   ```bash
-   mkdir -p vendor/highgo-pq
-   ```
-
-2. 解压下载的驱动源码到 `vendor/highgo-pq/` 目录
-
-3. 确保目录结构如下：
-   ```
-   GoNavi/
-   ├── vendor/
-   │   └── highgo-pq/
-   │       ├── go.mod
-   │       ├── conn.go
-   │       ├── ... (其他 pq 驱动源文件)
-   ```
-
-### 步骤 3：修改 go.mod
-
-在 `go.mod` 文件末尾添加 replace 指令：
-
-```go
-replace github.com/lib/pq => ./vendor/highgo-pq
-```
-
-完整示例：
-```go
-module GoNavi-Wails
-
-go 1.24.3
-
-require (
-    // ... 现有依赖
-    github.com/lib/pq v1.11.1
-    // ... 其他依赖
-)
-
-// 在文件末尾添加
-replace github.com/lib/pq => ./vendor/highgo-pq
-```
-
-### 步骤 4：更新 HighGo 连接配置（可选）
-
-根据瀚高官方文档，建议修改 `internal/db/highgo_impl.go:43` 的 sslmode：
-
-**当前代码**：
-```go
-q.Set("sslmode", "disable")
-```
-
-**建议修改为**（瀚高默认）：
-```go
-q.Set("sslmode", "require")
-```
-
-> ⚠️ 注意：如果您的 HighGo 服务器未配置 SSL，保持 `disable` 即可。
-
-### 步骤 5：验证集成
-
-1. 清理依赖缓存：
-   ```bash
-   go clean -modcache
-   ```
-
-2. 重新下载依赖：
-   ```bash
-   go mod download
-   ```
-
-3. 编译项目：
-   ```bash
-   go build ./...
-   ```
-
-4. 测试 HighGo 连接：
-   - 启动应用
-   - 创建 HighGo 连接
-   - 测试连接是否成功
-
-## 三、重要说明
-
-### ⚠️ 影响范围
-
-使用 `go.mod replace` 会**全局替换** `github.com/lib/pq` 驱动，这意味着：
-
-1. **PostgreSQL 连接也会使用瀚高驱动**
-2. **需要验证瀚高驱动对标准 PostgreSQL 的兼容性**
-
-### 兼容性验证
-
-集成后，请务必测试：
-
-1. ✅ HighGo 数据库连接（SM3 认证）
-2. ✅ 标准 PostgreSQL 连接（确保仍然可用）
-
-如果标准 PostgreSQL 连接失败，说明瀚高驱动不完全兼容，需要考虑其他方案。
-
-### 回滚方案
-
-如果集成后出现问题，可以快速回滚：
-
-1. 删除 `go.mod` 中的 replace 指令
-2. 删除 `vendor/highgo-pq/` 目录
-3. 运行 `go mod tidy`
-4. 重新编译
-
-## 四、瀚高驱动特性
-
-根据官方文档：
-
-- **包路径**：`github.com/lib/pq`（与标准版相同）
-- **驱动名**：`postgres`（与标准版相同）
-- **SM3 支持**：自动启用国密认证
-- **默认端口**：5866
-- **默认数据库**：`highgo`
-- **默认用户**：`sysdba`
-- **sslmode 默认**：`require`
-
-## 五、故障排查
-
-### 问题 1：编译失败
-
-**现象**：`go build` 报错找不到 `github.com/lib/pq`
-
-**解决**：
-1. 检查 `vendor/highgo-pq/` 目录是否存在
-2. 检查 `go.mod` 中 replace 路径是否正确
-3. 运行 `go mod download`
-
-### 问题 2：HighGo 连接失败
-
-**现象**：连接 HighGo 时报认证错误
-
-**解决**：
-1. 确认瀚高驱动已正确替换（检查 `go.mod`）
-2. 确认 HighGo 服务器支持 SM3 认证
-3. 检查用户名、密码、端口是否正确
-
-### 问题 3：PostgreSQL 连接失败
-
-**现象**：集成后标准 PostgreSQL 无法连接
-
-**解决**：
-1. 这说明瀚高驱动不完全兼容标准 PostgreSQL
-2. 需要考虑条件编译或其他隔离方案
-3. 临时回滚：删除 replace 指令
-
-## 六、后续优化建议
-
-如果发现瀚高驱动与标准 PostgreSQL 不兼容，可以考虑：
-
-1. **条件编译**：使用 Go build tags 分别编译两个版本
-2. **动态驱动注册**：如果瀚高驱动支持自定义驱动名
-3. **联系瀚高技术支持**：咨询官方兼容性方案
-
