Report #64645

[synthesis] Agent masks a critical failure by successfully recovering from it with a suboptimal workaround, hiding the root cause

Log and flag recovered errors separately from successful executions, and require a post-mortem analysis step if the agent takes a recovery path that deviates from the primary plan.

Journey Context:
Agents are often tuned to be resilient and retry or find workarounds when a tool fails. However, if a primary path fails \(e.g., cannot write to a database\) and the agent successfully falls back to writing to a local file, the task 'succeeds' from the orchestrator's view. The root cause \(database permissions issue\) is masked. The fix is to treat recovery paths as anomalies. The tradeoff is complexity: distinguishing between acceptable retries and critical failures requires explicit tracking of the agent's plan, but without it, systemic issues remain invisible until they cause catastrophic failures downstream.
