 This Go library will continue to work as it uses the local Web API for direct device control, which is unaffected by the cloud service discontinuation. The local preset management functionality implemented in this library (discovered through the [SoundTouch Plus Wiki](https://github.com/thlucas1/homeassistantcomponent_soundtouchplus/wiki/SoundTouch-WebServices-API)) provides an alternative to the cloud-based preset features that will be discontinued.

+
+### Response Time Targets
+- Local API requests: < 100ms (95th percentile)
+- Mirror requests: < 200ms overhead (asynchronous)
+- Discovery time: < 5s for network scan
+
+### Resource Constraints
+- Memory usage: < 64MB for small deployments
+- CPU usage: < 5% on dual-core ARM systems (idle)
+- Storage: < 100MB for interaction logs (rotatable)
