+The current public release is the `sentinel-01-pub` channel serving the `sentinel-mb-c-d11-20260424` artifact. The repository ships as a self-contained end-to-end model; the source encoder lineage is listed for transparency and Hugging Face discoverability, not because users need to load a separate encoder.
+
 The model was selected as a public, lower-capacity, limited-functionality variant. It is separate from Aurelex production channels and full-featured internal models.

-For reproducible evaluation, pin a reviewed Hub commit with `revision="<commit_sha>"`.
+`trust_remote_code=True` is required because this repository includes custom Transformers runtime files: `configuration_sentinel.py`, `modeling_sentinel.py`, and `pipeline_sentinel.py`. Those files register the `sentinel-stage-a` pipeline and the custom Sentinel model class used to interpret the serialized weights.

+Only use `trust_remote_code=True` for repositories you trust and whose code you have reviewed. For reproducible use, pin a reviewed Hub commit with `revision="<commit_sha>"` so the loaded runtime code and weights cannot change unexpectedly.
