Stressor Event¶

A stressor event is a hypothetical or real disruption that places a software system under pressure and reveals which architectural elements are truly stable. In Residuality Theory, architects use stressor events as deliberate probes, imagining scenarios such as regulatory change, infrastructure failure, or a surge in user load, and asking "what would break if this happened?" before it does. The elements that survive across many different stressors become the residuals that form the reliable core of the system, turning future uncertainty into actionable insight about where the architecture is fragile.
