The locked identity, rebuilt from client-supplied ground truth. Every asset is scored against the reference canon before it ships — the score sits on each tile, and nothing passes silently.
Eighteen reference tiles cropped from the two client-supplied biometric sheets that carry no annotation text. Internal cohesion measures 0.76–0.81 frontal-to-frontal, confirming one consistent individual. These tiles are the sole identity source for every generation; the annotated sheets are excluded so no label artifact can bleed into a render.
