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?
