Correct episodes exhibit higher variance slopes beta_t than incorrect episodes across all six task-LLM pairings. Separability is statistically significant (p < .001) for Math (Llama-3.1-8B), Code (Qwen3-14B), Retail (Qwen3-14B), and Retail (Qwen3-32B), but not statistically significant for Airline (Qwen3-14B, p=0.30; Qwen3-32B, p=0.057).
