[research] Scaling agent parallelism causes cost explosions and cascading failures

Enforce a minimum pass@k score on a deterministic regression suite before allowing an agent to scale to parallel runs or higher autonomy levels. Block deployment if base success rate is below threshold.

Journey Context:
Teams often try to solve agent unreliability by running them multiple times in parallel \(majority vote\). This multiplies costs and hides the root cause: the base agent is unreliable. If the base success rate is low, parallel execution yields diminishing returns and high cost. Eval-before-scaling forces fixing the underlying prompt/tool logic first.
