ConceptBoundary Assurance Stack
Boundary Assurance Stack
A layered safety architecture within the PASAC framework, spanning from risk tiering at the task design layer to scope contracts and egress enforcement at the execution layer, and further to cross-run behavior tracking at the monitoring layer. Each layer assumes that the others may fail and must be independently verified.

The five-layer boundary assurance stack provides a layered architecture approach: from risk grading at the task design layer, to scope contracts and egress enforcement at the execution layer, to cross-run behavior tracking at the monitoring layer, each layer assumes that the other layers may fail and therefore requires independent verification.
