Report #12251

[research] Scaling agent parallelism or autonomy causes unpredictable cascading failures

Freeze agent architecture and run a deterministic regression eval suite against a golden dataset before increasing autonomy levels or parallel execution counts.

Journey Context:
Developers often increase an agent's autonomy \(e.g., allowing 10 steps instead of 3, or running 50 concurrent agents\) before validating its reliability at 3 steps. This causes a combinatorial explosion in failure modes. You must 'eval before you scale': prove the agent succeeds on a constrained regression suite with >95% step-level accuracy before granting it more compute or freedom.
