# NTP Pool Monitor Changes

## v4.0.3

### Monitor Selection
- **Performance-based replacement**: Testing monitors can replace worse-performing active monitors
- **Safety thresholds**: Prevent removing all monitors when performance is universally poor
- **Auto-pause for constraint violations**: Monitors with unchangeable constraints (subnet/account) are paused instead of repeatedly failing
- **Data point requirements**: Minimum 9 measurements for testing promotion, 60 for active promotion
- **Account limit fixes**: Allow monitor swaps at account boundaries
- **Priority 0 fix**: Optimal performance monitors can now be promoted correctly

### Scoring & Reliability
- **Deadlock retry**: Exponential backoff for database deadlocks with telemetry
- **Paused server scores**: Added support for paused status in scoring

### Developer Tools
- **Simulation mode**: `selector simulate` command for safe algorithm testing
- **Server targeting**: `--server-id` parameter for processing specific servers
