Open-Ended Discovery Harnesses

Harness designs for hours-long agent runs on problems with no known optimum, where the recurring failure is idea collapse — committing to one approach early and micro-optimizing it forever; SwarmResearch's two moves (a global-context Shepherd steering branch-isolated Search Agents, one worktree per agent) match or beat EvoX/CORAL on 13/15 tasks, though all methods sit well below human SOTA on contest heuristics.
