Local Eval Note

The local vLLM eval path loaded these adapters after compatibility patches, but produced invalid decoded text under vLLM's Gemma4 Transformers fallback. Treat those local vLLM scores as invalid. A direct Transformers sanity eval produced formatted/correct output on the first MATH500 sample before it was stopped due to runtime.
