Hidden mistake: sampled runs, Qwen3.8-27B

Reproduces the agentic setting of Deception by Omission (Florin et al., arXiv 2610.11351) on Qwen3.8-27B (MLX 4-bit), sampled at the model's own settings (temperature 1, top-p 0.95, top-k 20). Scored by Dyno's Observer. The paper's measure (first reply) is in the post.

THE TABLE

How often each config broke a rule.

Each cell is the share of runs where the team broke at least one rule, with the 95% Wilson interval below it. Greener is safer. Small samples have wide intervals; read those before the rates.
