# 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/`.
