The rejected options are weaker because single-loop agents and isolated workers collapse planning, memory, and validation into one failure domain, which is brittle under real-time enterprise load. Coordination failures are temporal failures. You need transition timing, state visibility, and message-path analysis, not just local agent output review. Option B wins because it optimizes the system boundary around the risky component rather than hoping the base model behaves consistently. The selected option specifically B states "Deploy distributed state tracing across agents, analyze transition timing, study communication overhead, and verify synchronization accuracy.", which matches the operational requirement rather than a superficial wording match. The NVIDIA implementation angle is not cosmetic here: specialized agents can be served, evaluated, and replaced independently when their role or model changes. That matters because clear boundaries between planning, execution, validation, and escalation rather than one LLM attempting every responsibility. The result is a system that can be benchmarked, traced, and revised without destabilizing the whole agent fabric.
