 - **No tabs**: use spaces for indentation in all source files.
 - **No `fetch()` in templates** for page data — all API calls must go through Go server-side handlers. JS is only for UI interactivity (modals, carousels, confirm dialogs).
 - **No inline `onclick` with complex quoting** — use `data-*` attributes + event delegation instead.
-- **Use `pwsh`** for PowerShell commands (v7.6.4 in PATH — `C:\Program Files\PowerShell\7`, not `powershell.exe`).
+- **Use `pwsh`** for PowerShell commands on Windows dev machine (PATH 中的 PowerShell 7，勿用 `powershell.exe`；不要硬编码版本号)。测试盒子上用 bash（Ubuntu）。
 - **重启服务**：统一用 `pwsh -File scripts/safesightd.ps1 restart`，它会先编译、停旧进程、再启动新进程并做健康检查。不要手动 kill + build + start。
 - **如无必要，不使用数据库事务**：SQLite 只允许一个写者，事务会阻塞所有其他写操作。单个 `Exec` 已是原子操作，绝大多数场景不需要包裹事务。仅模板重命名等必须原子完成的多步操作才用事务。
 - **调试时只加日志，不改代码**：遇到 bug 先用 `fmt.Printf` 全量打印关键路径的状态和数据流，定位根因后再动手修。不要猜测、不要加 workaround（重试、超时、锁之类）。

 ## Shell Environment Rules
 
-- For agent-run shell commands on this workstation, use PowerShell 7.6 (current: 7.6.4, installed at `C:\Program Files\PowerShell\7\pwsh.exe`, first in user PATH) instead of Windows PowerShell 5.1.
-- Prefer invoking `pwsh` from PATH (resolves to 7.6.4); do not hardcode old WindowsApps MSIX paths (`Microsoft.PowerShell_7.6.0.0` is obsolete).
-- Do not rely on the system-default `powershell.exe` resolving to the desired version.
+- **Windows 开发机**：PowerShell 命令用 `pwsh`（PATH 中的 PowerShell 7，勿用系统默认 `powershell.exe` 5.1）。不要硬编码具体版本号或 WindowsApps MSIX 路径——升级后即过时。
+- **Ubuntu 测试盒子**：脚本语言为 bash（设备端本身也是 bash），直接用 bash/sh 执行。
