[research] Scaling up agent compute/parallelism increases cost but not success rate

Implement eval-before-scaling: gate parallel branch scaling or increased token limits behind a baseline single-thread pass@1 eval. If pass@1 < threshold \(e.g., 30%\), scaling compute will only amplify failure modes. Fix the base prompt/tool first.

Journey Context:
It is tempting to throw more agents at a problem \(e.g., tree of thought, parallel rollouts\) when accuracy is low. However, if the base agent lacks the tools or context to solve the problem, parallelizing just creates expensive, concurrent failures. Eval-before-scaling forces you to prove the task is fundamentally solvable before optimizing the search strategy.
