What it demonstrates
Uncertainty should increase when a query moves away from the region supported by training and validation evidence.
L03 / Interactive laboratory
AI validity-range explorer
Explore why prediction uncertainty should grow outside the region represented by training and validation evidence.
Educational model
Values are synthetic and dimensionless unless labelled. This laboratory illustrates relationships; it is not a solver, design tool, validation result or client-project output.

What it does not demonstrate
The band is an educational construction, not calibrated probabilistic confidence and not evidence for a deployed model.
Practical question
Can the system recognize unsupported inputs, reduce its authority and route the decision to a safer fallback?
