Report #56056

[frontier] Agents lose track of authoritative information source when DOM and screenshot conflict \(e.g., DOM says button enabled, screenshot shows it greyed out\)

Implement Ground Truth Pinning: tag every observation with source modality, timestamp, and confidence; prefer DOM for structural truth \(hidden/visible\) and screenshot for rendered state \(disabled styling\), reconcile using temporal logic \(screenshot lags DOM by ~50-100ms\)

Journey Context:
In SPAs like React apps, DOM updates immediately on state change but screenshot captures browser render pipeline \(layout, paint, composite\). Mind2Web datasets show agents double-clicking because DOM said 'ready' but screenshot showed 'loading'. The fix requires understanding the browser event loop timing.
