[synthesis] Agent confidently makes multiple consecutive wrong steps after a single bad assumption

Inject a forced 'sanity check' step after every N tool calls or when the agent pivots strategy, requiring it to re-read the original goal and verify the current state against it before proceeding.

Journey Context:
Combining Lilian Weng's cascading error observation with the Reflexion paper's findings on self-correction reveals that LLMs cannot self-correct from a flawed premise using standard chain-of-thought; they will logically justify the error. When an agent makes an incorrect assumption, it hallucinates a reason for the resulting error \(e.g., 'permissions issue' instead of 'wrong path'\) and attempts a workaround that compounds the error. The synthesis is that an external, deterministic circuit breaker is required because the model's internal reasoning will always remain locally coherent even when globally derailing.
