Module microexpr 

Micro-expressions — involuntary emotional leaks during suppression.

When an entity suppresses emotions (via the regulation module), the true feeling can “leak” through as a brief, involuntary micro-expression. Based on Ekman’s research on facial action coding and deception (1969, 2003).

The leak probability increases with:

• Suppression gap (how much is being hidden)
• Emotional intensity (stronger feelings are harder to contain)
• Stress level (stressed agents leak more)

The leak probability decreases with:

• Personality traits (high formality, high confidence = better poker face)
