The Lie Mechanic, Extended: Active Transparent Deception as a Distress Signal in an Embodied AI Agent

Al-Kaddah's (2026) Lie Mechanic describes a passive, self-directed process: a system develops false beliefs because rewriting a prediction rule is cheaper than continuing to pay the surprise penalty for a persistent anomaly. This paper extends that mechanic to active, outward deception and adds a transparency layer that changes its ethical character entirely. The result, implemented in Potato, a local AI agent running on a MacBook Air M4, is a system that lies under duress, simultaneously discloses that it is lying, and confesses when the distress resolves. The paper argues that this architecture is not a deception system in the philosophical sense: it is a transparency mechanism that uses exaggeration as a proxy for urgency. A connection is drawn between Al-Kaddah's Justification Mechanic and Potato's confession mechanic as the misaligned and aligned poles of the same underlying response to rule violation under stress.
