- providers overlay: new `[suppress] routes = ["provider:model_id", ...]` section hides broken or product-unsupported routes from the exported/served catalog artifact — the model row, its aliases, and any recommendation variant derived from it — without forking the baseline. Selectors split on the first colon (model ids may contain colons, e.g. Ollama image tags). Combined with whole-row `models` replacement this also expresses route renames (define the new id, suppress the old), letting embedders drop post-export catalog patching (#3267)
