[synthesis] Agent confidently terminates after achieving partial success that masks total failure

Require the agent to explicitly map the final state back to the original goal constraints, using a separate verification step or a distinct 'critic' agent that does not share the 'actor' agent's confirmation bias.

Journey Context:
A single agent evaluating its own work suffers from confirmation bias—it wants to be done. If it writes a passing test, it assumes the feature works. A separate critic, or a strict constraint-checking prompt, breaks this loop. The tradeoff is increased token cost and latency, but it prevents catastrophic silent failures where the agent declares victory while leaving the core task unfinished.
