HarnessMutation

Governed Evolution of Agent Runtimes through Executable Operational Cognition

This paper proposes a framework for governed runtime evolution in multi-agent systems, formalizing agent-generated code artifacts as persistent runtime capabilities rather than transient outputs. It introduces HarnessMutation, a lifecycle-aware mechanism for runtime adaptation operating under explicit validation, traceability, evaluation, and rollback constraints. The framework models agent self-modification as a bounded, observable, and auditable process over persistent operational memory, building on prior 'Code as Agent Harness' work.
