[synthesis] Long-horizon plan becomes detached from environment state
Re-ground the plan against observable state after every action and invalidate any plan step whose preconditions are not verifiable.
Journey Context:
STRIPS planning emphasized preconditions for a reason, yet LLM agents such as Voyager and Reflexion often generate a plan once and follow it until completion. As context windows shrink and details fade, the plan drifts from reality. Better initial prompting is not enough; the fix is continual re-verification of preconditions, which is more expensive but prevents cascading actions on false assumptions.
