Report #2351

[research] Agent silently degrades by taking longer paths or looping without explicit failures

Implement trace-level evals on step count and tool call duration. Set anomaly thresholds for step-count-per-task-type; alert on upward drift.

Journey Context:
Agents rarely fail loudly; they just retry or take suboptimal paths. Final outcome evals mask this because the agent eventually succeeds, but at 10x the cost/latency. Tracking step-count distributions over time catches silent degradation before it impacts SLAs or burns compute budgets.
