Report #76933

[frontier] Step-by-step observe-think-act loops accumulate 3-5s latency per step, making agents impractical for long tasks

Predict N future actions in a single inference call \(action chunking\), execute sequentially with lightweight state validation between steps

Journey Context:
Standard ReAct pattern is too slow for GUI tasks. OpenAI's CUA and leading implementations use chunking to amortize inference cost. Risk: if UI state changes unexpectedly \(popup appears\), the chunk is invalid. Mitigation: validate state after each sub-action or use short chunks \(2-3 actions\).
