[synthesis] Agent becomes confidently wrong for multiple consecutive steps because it uses its own previous outputs as the sole source of truth

Inject external grounding \(e.g., a fresh retrieval step or a read from the actual file system\) at fixed intervals, explicitly instructing the agent to verify its assumptions against the external state.

Journey Context:
In a long chain of thought, if the agent hallucinates a variable name in step 1, it will confidently use it in steps 2, 3, and 4. Because the context window only contains its own text, there is no friction. The synthesis is linking the 'echo chamber' effect in autoregressive generation with the lack of external grounding in long-horizon agent loops. It's not just that it hallucinates; it's that the loop architecture validates the hallucination by carrying it forward.
