# 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
### Build Results (v0.4.0)

## Architecture
```
┌─────────────────┐ Policy ┌─────────────────┐
│ RMM Server │ ──────────────► │ Agent Service │
│ (WebSocket) │ │ (Background) │
└─────────────────┘ └────────┬────────┘
│ IPC
│ (Named Pipe)
┌─────────────────┐
│ Tray App │
│ (User Session) │
└─────────────────┘
```
- Named pipe: `\\.\pipe\gururmm-agent`
- Agent runs as SYSTEM, tray runs in user session
- Policy controls: visibility, menu items, allowed actions

## Pending Tasks
1. **Deploy Windows binaries** to downloads server
2. **Implement tray launcher** in agent (auto-launch in user sessions)
