Trail uses a local model to choose rooms, devices, and operations from a home’s runtime registry rather than generate complete commands. It makes sequential typed decisions and refuses when path confidence falls below a threshold. On simulated Trek-Robust, exact-match accuracy is 85.3% versus 69.8% for finetuned Qwen3.5-4B, but Trail trails on Trek-Base; neither benchmark establishes deployment safety.
