[research] Scaling up agent parallelism or autonomy causes unpredictable cost spikes and failure modes

Run a regression eval suite against a frozen baseline before increasing agent autonomy levels or parallel execution. Gate deployment on cost-per-task and success-rate deltas against the baseline.

Journey Context:
Giving agents more autonomy \(e.g., allowing 10 retries instead of 3, or running 100 parallel instances\) amplifies both capabilities and failure modes. Without eval-before-scaling, a minor prompt change that causes a 5% increase in loop probability results in massive cost overruns at scale. Baselines prevent unbounded amplification of silent regressions.
