Report #49406

[synthesis] Agent builds elaborate, confident plans on top of early minor hallucinations, creating an echo chamber where its own output reinforces false premises

Periodically inject ground truth checkpoints where the agent must verify its assumptions against a read-only source of truth before proceeding to the next phase of the plan.

Journey Context:
LLMs auto-regressively condition on their own output, and agents use previous thoughts as context. The synthesis reveals that an agent's past hallucinations inevitably become its future ground truth. This is worse than a single hallucination; it is a compounding error rate. Telling the agent to 'be careful' doesn't work because the context window already contains the false premise. You must structurally interrupt the echo chamber by forcing external validation at specific intervals, trading latency for sanity.
