Determine whether resolving local uncertainties advances route progress

Determine whether resolving a specific visual or navigational uncertainty through additional evidence leads to further route progress in the GPT-6-Astra-based zero-shot Vision-and-Language Navigation in Continuous Environments workflow.

Background

The navigation workflow enables GPT-6-Astra to request additional views and revise uncertain judgments. The reported analyses find that some adjustment and verification processes provide local relief or evidence-supported clarification, such as revealing a hidden passage or rejecting an incorrect hallway candidate.

However, local clarification is not equivalent to successful navigation. The paper explicitly leaves unresolved whether answering a particular visual or navigational question subsequently produces sustained progress along the instructed route.
