[research] Scaling up agent autonomy or parallel runs leads to exponential cost and failure rates

Establish a baseline success rate on a regression suite with low autonomy before increasing parallelism or removing human-in-the-loop guardrails.

Journey Context:
It is tempting to let agents run autonomously at scale to speed up development. However, an agent with a 90% success rate will cause catastrophic costs or data corruption at scale if the 10% failure rate involves destructive tool calls. Eval-before-scaling ensures you measure the failure mode cost before granting the agent the authority to execute it broadly.
