TL;DR. Best reward comes with the LoRA at 50% (0.521), beating BASE_P (0.496) and BASE (0.490), while higher merges fall apart (LoRA100 0.344, LoRA150 0.372). Recommendation: use the evolved prompt plus a 50% LoRA. The gain is a genuineness lift (0.140 to 0.172) with blend held roughly steady (~0.423); the trade-off is a small quality drop (0.551 to 0.503) and higher WER (0.196 to 0.302). One caution: the evolved prompt alone tends to make confusion sound irritated rather than doubtful (BASE_P correlates positively with Anger/Teasing and negatively with Doubt at -0.51), whereas the LoRA instead pulls in Fatigue and Fear and suppresses Concentration.
Without a LoRA
Best: evolved prompt, no LoRA → reward 0.50
GENERAL: A voice powerfully expressing confusion, a baffled, disoriented voice, struggling to make sense of things, hesitant and lost, pouring out.
