Chen and colleagues present RankEvolve, a harness that automates repeated proposal, implementation, training and evaluation of ranking-model changes while enforcing a predefined experimental process.

The authors encoded the research workflow as an Executable Operating Protocol, a state machine specifying phases, decision gates, branches and loops.
