Gemma3-270M-EU-Medical-CandidateSelector-LoRA
LoRA adapter for unsloth/gemma-3-270m-it.
This model is a candidate-conditioned German/EU medical terminology selector.
It is not a diagnostic model. It must not be used for treatment, prescribing, dosage, triage, or clinical decision-making.
Intended role
Verifier retrieves ICD/EMA candidates → 270M LoRA selects or flags ambiguity → Verifier confirms selected candidate → MedGemma explains verified facts.

Trust boundary
Trusted for:
- valid JSON
- candidate selection from provided lists
- ambiguity/non-terminal flagging
- terminology-only safe outputs
Not trusted for:
- free-generation of ICD codes
- free-generation of EMA metadata
- diagnosis
- treatment advice
- dosage advice
Production rule
The selected code or medicine must be verified against deterministic SQLite/EMA tables and must be present in the provided candidate list.
The verifier should overwrite metadata fields from deterministic sources:
