[research] Scaling agent parallelism increases error rates exponentially

Freeze agent architecture and run a regression eval suite \(pass@k\) before increasing autonomy or parallel execution. Never scale concurrency without a baseline eval pass rate > 90%.

Journey Context:
It is tempting to throw more compute or agents at a problem to speed it up. However, if an agent has a 10% failure rate per step, a 10-step parallel run has a massive compounding failure rate. Scaling amplifies existing flaws. Eval-before-scaling ensures you are multiplying success, not failure, and prevents cascading orchestration breakdowns.
