[research] Scaling agent autonomy or parallelism causes exponential cost and failure rates

Run a lightweight regression eval suite on a single-threaded agent before increasing autonomy or parallel execution limits.

Journey Context:
Developers often try to fix bad agent behavior by adding more agents or letting them run longer. This just multiplies errors and costs. An agent must achieve a high success rate \(e.g., >90%\) on a constrained eval suite before granting it more autonomy or parallel runs. Eval-before-scale prevents runaway token spend and cascading failures in production.
