Gölge Vadisi: Behavioral Digital Twin

An RPG that works as a behavioral digital twin. Candidates play a three-day story across a valley map of 16 locations, in Turkish or English; 93 of its 98 scenes are scored, and each choice becomes evidence for a Bayesian twin of 12 core traits and of the personality inventory's 22 sub-dimensions and eight main dimensions. Evidence rules tie every choice to target traits, context contrasts catch how the same behavior differs under different conditions, and the engine tracks witness gaps, engagement, manipulation and attempts to fake good. The twin is compared with the inventory through the inventory's own scoring code, a chance-corrected kappa with a permutation test and T scores from a norm table; random play scores 0.50. It complements the questionnaire rather than replacing it, carrying at most 30 percent of the combined score. Version 3.7 is live; an expert panel (content validity, CVI) and a playtest come first, then a pilot of 150 to 300 people for norms.
