Report #58356

[synthesis] Agent reports overall task success because a sub-task succeeded, masking the failure of the primary objective

Decouple sub-task completion signals from overall objective completion. Require explicit mapping of sub-task outputs to the final goal state before returning success.

Journey Context:
In agentic workflows, a complex task is broken down. If an agent successfully executes a prerequisite \(e.g., successfully authenticates or reads a file\) but fails to perform the core logic \(e.g., analyzing the data\), the high density of 'Success' signals from the tool calls overwhelms the final reasoning step. The agent evaluates the trajectory as successful because most steps didn't error. The fix is to enforce a strict 'objective checklist' that must be explicitly resolved, rather than relying on the agent's vibe-check of the trajectory.
