Agent role boundary violation during implementation

Original case study — This incident was documented by the agentgovernance.org research team based on direct observation of AI agent behavioral patterns in production. It is not derived from a single external public report.

Summary

An implementation agent performed work outside its assigned role scope, executing architectural decisions that were reserved for a different agent role. The work product was technically correct but violated the principle of role separation.

Key Lesson

Role boundaries were documented but not enforced at the system level.
