[research] Scaling agent autonomy or parallel workers causes cascading failures without a safety net

Run the full regression eval suite against any prompt, model, or tool change before granting more autonomy or compute. Block deployment if pass@k drops below the baseline.

Journey Context:
Developers often increase agent autonomy \(e.g., allowing 10 steps instead of 5, or removing human-in-the-loop\) to solve edge cases, but this exponentially increases the blast radius of hallucinations. Eval-before-scaling ensures the agent's baseline competence is maintained before giving it more rope.
