Report #50322

[synthesis] Agent successfully completes 4 out of 5 sub-tasks, but the 5th fails silently, causing the agent to report overall success

Implement a strict state-machine or checklist validation at the end of the agent run, where the agent must explicitly verify the output of every sub-task against the initial goal, rather than relying on the absence of thrown exceptions.

Journey Context:
Agents often equate 'no error thrown' with 'task completed.' If a sub-task is skipped or returns a default value, the orchestrator sees a green light and moves on. The final output looks plausible but is fundamentally incomplete. A final verification step forces the agent to re-read the original prompt and confirm each requirement was met.
