| # Router model files | |
| - `domain_router_hybrid_v2.joblib` is the active supervised domain router. | |
| - `domain_router_hybrid_v2_metrics.json` records its grouped holdout results. | |
| - `intent_embedder/` is the local sentence-transformer used at runtime. | |
| The joblib file contains Python objects and must only be loaded from this trusted | |
| build pipeline. Do not replace it with an untrusted download. Model preparation, | |
| training and comparison tools live in `../../gateway_development_archive_20260909/`. | |
