# Stateful Systems
**Domain:** Computing / Systems Architecture
**Doc Type:** Concept
**Maturity:** Developed
**Related:** [[Operational State Machines]], [[Enigma]], [[Self-Reference]], [[wiki/Bauhaus Architects of AI|Bauhaus Architects of AI]]
## Definition
Stateful systems retain information from prior operations so later behavior depends on both current input and accumulated state.
## Corpus Context
Statefulness is not self-reference. A machine may change behavior according to stored state without representing or describing itself.
