Report #44678

[frontier] Agent generates text plans like 'click the red button' but loses spatial grounding when executing, clicking wrong red button in a grid or dense layout after intermediate reasoning

Enforce that every text reasoning step must reference explicit visual coordinates or SOM IDs, maintaining a 'grounding chain' where text plans are always anchored to specific pixel regions or bounding boxes, never abstract descriptions, and validating that reasoning chains remain spatially consistent across steps

Journey Context:
Standard chain-of-thought allows pure text reasoning \('the submit button should be clicked'\). In dense UIs \(data tables, dashboards with multiple similar buttons\), this leads to coordinate hallucination because the text model forgets which specific instance it was referring to. The grounding chain pattern forces the agent to 'point' at what it's talking about via coordinates or SOM IDs during the reasoning phase, not just the action phase. This creates an audit trail of visual attention that prevents 'reference drift' when the agent gets distracted by intermediate calculations.
