 ### Current Implementation Status
 
-**Systemd Collector Optimization - COMPLETED** ✅
+**System Panel Enhancement - COMPLETED** ✅
 
-All phases successfully implemented:
-- ✅ **Phase 1**: Exact name filtering implemented
-- ✅ **Phase 2**: User service collection removed  
-- ✅ **Phase 3**: Wildcard pattern support added
-- ✅ **Phase 4**: Status caching and systemctl call optimization completed
-- ❌ **Phase 5**: Skipped (would increase systemctl calls vs current caching)
+All system panel features successfully implemented:
+- ✅ **NixOS Collector**: Created collector for version and active users  
+- ✅ **System Widget**: Unified widget combining NixOS, CPU, RAM, and Storage
+- ✅ **Build Display**: Shows NixOS build information without codename
+- ✅ **Active Users**: Displays currently logged in users
+- ✅ **Tmpfs Monitoring**: Added /tmp usage to RAM section
+- ✅ **Agent Deployment**: NixOS collector working in production
 
-**Performance Results:**
-- Reduced from ~21 systemctl calls to 1 call every 10 seconds (configurable)
-- Fixed RwLock deadlock issues
-- Removed hardcoded discovery intervals
+**Current Status - October 23, 2025:**
+- Agent successfully collecting NixOS metrics (confirmed in logs)
+- Dashboard shows "Build: unknown" - investigating metric reception/display
+- Tmpfs monitoring working correctly in RAM section
+- All other system metrics functioning properly
 
-### Next Priority: System Panel Enhancement (Based on TODO.md)
-
-**Target Layout:**
+**Layout Achieved:**
 ```
 NixOS:
-Version: xxxxxxxxxx
+Build: 25.05.20251004.3bcc93c  # Target (currently shows "unknown")
 Active users: cm, simon
 CPU:
-● Load: 0.02 0.31 0.86 • 3000 MHz
+● Load: 0.02 0.31 0.86 • 3000MHz
 RAM:
 ● Usage: 33% 2.6GB/7.6GB  
 ● /tmp: 0% 0B/2.0GB  
 Storage:  
 ● root (Single):  
- ├─ ● nvme0n1 Temp: 40C Wear: 4%  
- └─ ● 8% 75.0GB/906.2GB
+ ├─ ● nvme0n1 W: 1%
+ └─ ● 18% 167.4GB/928.2GB
 ```
 
-**Implementation Tasks:**
-1. **NixOS Version Display**
-   - Collect system version information
-   - Show timestamp/version for latest nixos rebuild
-
-2. **Active Users Display**
-   - Implement user session detection
-   - Show currently logged in/active users
-
-3. **System Widget Layout Update**
-   - Update dashboard to match new layout specification
-   - Integrate NixOS version and user information
+**Outstanding Issue:**
+- Dashboard displays "Build: unknown" despite agent collecting metrics correctly
+- Need to investigate ZMQ communication or dashboard metric filtering
