Adversarial / negativeepiphenomenal-templateQwen/Qwen3.6-27B-Instruct2026-05-11 · by caiovicentino

L55 CoT-Integrity probe is template-locked epiphenomenal (Qwen3.6-27B)

N=240. AUROC 0.91. Bidirectional steering up to α=+200 (>‖residual‖) produces ZERO behavioral change for probe AND random direction. Mechanism: enable_thinking=False chat template injects <think></think> in input tokens — thinking decision is not in residual stream.

Reproduce this in your agent

In an agent session attached to your Colab via openinterp-mcp:

from openinterp_mcp.atlas import load_entry

entry = load_entry("a0c01e67c9")
print(entry.methodology_check)

# Re-run the causality protocol against the linked HF artifact:
