Multilingual DistilBERT Scope Intent Router

This full fine-tune of distilbert/distilbert-base-multilingual-cased routes requests into:

• DIRECT_RESPONSE: no external state or structured scope resolution is needed.
• REQUIRES_SCOPE_CONTRACT: tools or external state are needed, so a scope contract should be resolved first.

Use the conservative threshold stored in router_metadata.json.

Held-out synthetic-family evaluation

The split contains 3,000 examples from seed families excluded from training. These are synthetic results and do not establish production accuracy.
