Graph attention for tier-n risk propagation

The advanced question in graph attention for tier-n risk propagation is how the model behaves when assumptions fail. A sound design makes uncertainty, constraints and fallback actions explicit.

Practitioner lens

A model for graph attention for tier-n risk propagation should state its objective and feasible set explicitly. Hidden penalty weights or relaxed constraints can make an impressive result operationally impossible.

First experiment

Write down the objective, constraints, uncertainty set and decision horizon before selecting a solver or model.
