peripheral machine
A model is denied the center of the image and must infer it from peripheral evidence while confidence becomes geometry rather than text.
surface
The visitor sees the full camera view while the machine sees everything except the center.
disturbance
Camera motion changes the peripheral evidence, causing the hidden interpretation to stabilize, fragment, or abruptly switch.
recognition
Both biological and machine perception can complete missing structure from context, but certainty does not guarantee direct evidence.
system
Camera masking, bounded vision inference, temporal confidence tracking, and a non-text procedural confidence field.
