# Session Log: GuruRMM v0.4.0 Build with Tray Icon
**Date:** 2025-12-20
**Focus:** Tray icon implementation, cross-platform builds

---

## Summary

Built GuruRMM v0.4.0 with new system tray application for Windows.

### Completed

1. **Tray Icon Implementation** (from previous session)
   - IPC infrastructure in `agent/src/ipc.rs` (Named Pipe for Windows)
   - TrayPolicy struct for admin-controlled visibility
   - Tray app crate with menu, icon states, IPC client
   - SVG icon assets (green/yellow/red/gray states)

2. **Compilation Fixes**
   - Fixed `device_id::get_device_id()` return type (String, not Result)
   - Added `TrayPolicyUpdate` match arm in WebSocket handler
   - Added `last_checkin` and `tray_policy` fields to Windows service AppState
   - Fixed tray-icon API change (`set_menu` returns unit now)

3. **Cross-Platform Builds**
   - Installed mingw-w64 via Homebrew on Mac
   - Added `x86_64-pc-windows-gnu` target to Rust
   - Configured cargo for Windows cross-compilation

```

- Named pipe: `\\.\pipe\gururmm-agent`
- Agent runs as SYSTEM, tray runs in user session
- Policy controls: visibility, menu items, allowed actions
