[research] Scaling agent parallelism or complexity causes compounding errors and cost explosions

Gate agent scaling \(e.g., increasing max iterations, adding sub-agents, parallel tool calls\) behind a regression eval suite. Only scale if the pass@1 on the regression suite remains stable.

Journey Context:
It is tempting to give agents more autonomy to solve harder problems. However, agent error rates compound exponentially with each step. Without a regression suite, scaling autonomy just scales failure modes and token costs. Eval-before-scaling ensures you only increase complexity when the base reliability justifies it.
